The Best Big Bass Slots to Play in the UK (2025 Guide)

Fishing slots don’t get bigger than Pragmatic Play’s Big Bass online slots series. What started as a simple 5-reel game back in 2020 has grown into one of the most popular slot franchises on the planet. UK slot players can now choose from more than a dozen versions, each with its own twist — from Megaways to Hold & Spinner, festive editions, and even Vegas neon specials.

At WinLottoJackpots, we’ve played them all. We know what makes each slot tick, and more importantly, we know where to play them. If you’re looking for the best Big Bass slots in 2025 and the top UK casinos to play them (including MrQ), this is your ultimate guide.

Why Big Bass Slots Are So Popular

The formula is simple but addictive:

• Classic fishing theme with bright, cartoon visuals.
• Free spins with the Fisherman Wild collecting cash fish.
• Progressive retriggers and multipliers that can turn small wins into serious payouts.
• Variations that keep the series fresh but familiar.

Each new Big Bass release builds on the original. Sometimes it’s extra features like Hold & Spinner. Other times it’s Megaways with 46,000+ paylines. Whatever the format, the hook is always the same: big potential wins and fun fishing vibes.

Best UK Slots Site to Play Big Bass Games

When it comes to fishing for wins, MrQ Casino is easily the best site to play Big Bass slots in 2025. The operator has built a reputation as one of the top UK online casinos thanks to its clean design, fast gameplay, and a library packed with Pragmatic Play hits. What really sets MrQ apart is the seamless mobile experience and transparent approach — no hidden catches, just pure slot action. Big Bass titles load quickly, bonus rounds trigger smoothly, and payouts land without hassle. Add to that frequent promotions, regular free spins deals, and a user-friendly platform, and it’s easy to see why MrQ Casino is the number one destination for UK slots players chasing those Big Bass jackpots.

The Best Big Bass Slots in 2025

Here’s our complete breakdown of the series, with key features and why we like each one.

1. Big Bass Bonanza

• Reels/Paylines: 5 reels, 10 paylines
• RTP: 96.71%
• Max Win: 2,100x
• Volatility: Medium-High

The original and still a favourite. Free spins are triggered by 3 or more Scatters. Fisherman Wilds collect fish Money symbols, and every 4th Wild retriggers spins with multipliers up to 10x. Simple, accessible, and perfect for new players.

Why we like it: A great entry point into the Big Bass series. Clear mechanics, solid RTP, and decent win potential.

Big Bass Bonanza is where it all started. Back in 2020, Pragmatic Play (with Reel Kingdom) cast their line into slot waters and hauled in what would become one of the most iconic UK slot series of the last decade. It’s easy to see why it hooked so many players. On the surface, Big Bass Bonanza looks like a simple fishing-themed slot, but under the waterline there’s enough depth to keep you spinning long after the first cast.

Graphics and Vibe

The design is pure blue skies and bright waters. Think cartoon fishing trip with bold, chunky graphics. The reels float in a glassy lake, and fish of all shapes and cash values swim across them. It’s cheerful, colourful and very easy on the eyes – the kind of slot you can play on mobile for a quick few spins or settle into for a longer session without getting screen fatigue. The fisherman character – bearded, green hat, rod at the ready – is central to the charm. He’s also your wild symbol, and he’ll show up in the free spins to scoop up your catches.

Base Game Play

Big Bass Bonanza keeps it simple. It’s a 5-reel, 3-row slot with 10 fixed paylines. The volatility is medium-to-high, so don’t expect constant payouts, but the rewards can come in chunky bursts when they do land. RTP sits at a respectable 96.71% – enough to keep it competitive with other MrQ slots in 2025. Bets start at just 10p, making it accessible for casual players, while max stakes push up to £59 for those who want more action.

Bonus Features

Here’s where Big Bass Bonanza really shines. Land 3 or more scatters and you’re into free spins. You’ll start with 10, 15, or 20 depending on how many scatters you triggered with. During free spins, those money fish symbols are key. Each fish carries a random cash value. Land a fisherman wild alongside them, and he collects the lot – sometimes filling your net with a surprisingly big win.

But it doesn’t stop there. Every 4 fishermen you collect retriggers the bonus and adds multipliers – 2x, 3x, and up to 10x on fish values. That progression is what keeps the adrenaline pumping. You’re always watching the top of the screen, hoping the next fisherman pushes you into the next stage. It’s classic, it’s simple, and it still feels exciting even years after release.

Why We Like It

Big Bass Bonanza is the perfect starting point for anyone new to fishing slots. It’s accessible, bright and fun, but with just enough volatility and bonus potential to keep seasoned slot players engaged. At MrQ Casino in 2025, it remains one of the best MrQ slots for players looking for a classic with genuine win potential.

2. Big Bass Splash

• Reels/Paylines: 5 reels, 10 paylines
• RTP: 96.71%
• Max Win: 5,000x
• Volatility: High

Big Bass Splash adds Wild West flavour. Before free spins begin, up to 5 random modifiers can boost your chances, such as extra fish, more Wilds, or guaranteed scatters. Retriggers stack up to 10x multipliers.

Why we like it: More variety than the original, with fun modifiers that can turn average bonus rounds into big wins.

When Pragmatic Play first announced Big Bass Splash, slot fans wondered: how do you improve a classic? The answer was simple – give it a Wild West twist and pile on the features. Big Bass Splash takes the proven Bonanza formula and cranks it up with fresh modifiers, stickier scatters, and a bigger max win of 5,000x your bet. This one isn’t just a fishing trip – it’s a rodeo on water.

Graphics and Presentation

The vibe here is louder, bolder, and unapologetically cartoonish. The fisherman’s swapped his quiet day at the lake for a cowboy hat and monster trucks on the reels. It’s still instantly recognisable as part of the Big Bass series, but the detail has been ramped up: sharper visuals, more colourful animations, and a cheekier energy.

Backgrounds are brighter, the soundtrack feels punchier, and overall there’s more “arcade” to the presentation than the chilled-out tone of the first game. On mobile, it holds up brilliantly – portrait or landscape, you’re always in for a smooth ride.

Core Gameplay

The bones are the same: 5 reels, 10 paylines, high volatility, and an RTP of 96.71%. Bets range from 10p up to £25, making it slightly less broad on the upper end than the original, but still very accessible. What you notice quickly is how fast-paced it feels – scatter nudges, sticky reels, and modifiers keep you on edge even in the base game.

Bonus Features

This is where Big Bass Splash pulls ahead of the original.

• Scatter Nudge: Land 2 scatters and you’re not done – they can stick and trigger a re-spin to potentially land a 3rd. That extra bite at the cherry is a lifesaver.
• Free Spins: Three or more scatters activate free spins, as expected, but before the round begins, you’re handed up to five random modifiers. These could mean more fish symbols, extra wilds, guaranteed Money symbols, or even starting the round from a higher multiplier level. It’s like supercharging the classic free spins with new twists every time.
• Wild Collect Trail: Just like before, fishermen collect fish values, but here the trail feels more dynamic thanks to those added modifiers. Hitting retriggers feels less like a grind and more like an event.

Why We Like It

Big Bass Splash is where the series started evolving. It keeps everything that worked about the first slot but adds more chaos, more rewards, and more fun. The random modifiers ensure no two bonus rounds feel the same, and the cowboy theme gives it a shot of personality. At MrQ Casino in 2025, this one stands out as one of the best Big Bass slots for players who want that bit more bite from their bonus features.

3. Big Bass Bonanza Megaways

• Reels/Paylines: 6 reels, 46,656 paylines
• RTP: 96.72%
• Max Win: 4,000x
• Volatility: High

The Megaways upgrade brings cascading reels and over 46,000 ways to win. Free spins work like the original, but with more chaos and potential. Multiple Fisherman Wilds collect fish values separately, doubling or tripling payouts.

Why we like it: Huge paylines, cascading wins, and a supercharged version of the classic.

Big Bass Bonanza Megaways is where the series flexes its muscles. Pragmatic Play has taken the original fishing classic and dropped it into the Megaways engine, instantly turning a straightforward slot into one of the most exciting variations in the Big Bass franchise. On paper, it’s simple: six reels, cascading wins, and up to 46,656 paylines on every spin. In practice, it’s a high-voltage fishing trip that keeps you hooked from the very first cast.

The visuals stick to the familiar Big Bass aesthetic. You’re back on the open water, with bubbling reels, rods, floats, and of course, the fisherman himself waiting to step in and snag your prizes. It’s colourful without being cartoonish, and that’s a big part of the charm. The action feels tight and modern, which matters when you’re chasing cascades across thousands of paylines.

Gameplay is where Megaways earns its stripes. Wins don’t just land — they trigger cascades, where matched symbols disappear and new ones fall into place. That opens the door to consecutive wins in a single spin, a mechanic that keeps the pace snappy. When the fisherman joins the reels in free spins, things shift into top gear. He acts as the Collect symbol, grabbing all the values from the Money fish symbols. The kicker? If more than one fisherman lands, they all collect the total values, essentially doubling (or tripling) your catch.

The free spins round is where the real magic happens. Land three or more Scatters and you’re in. Collect fishermen during the round and the bonus upgrades with retriggers and multipliers. Four fishermen means 10 extra spins and a 2x multiplier. Eight fishermen? Another 10 spins and a 3x multiplier. Go all the way to 12 fishermen and you’re looking at a 10x multiplier on every Money symbol catch. It’s a structure that builds tension brilliantly, and every spin has that edge-of-your-seat anticipation.

Volatility sits firmly in the medium-to-high bracket, so expect dry spells followed by sudden bursts of action. RTP is a strong 96.72%, and the maximum payout is 4,000x your stake — more than enough to keep you fishing for the next big one.

Why we like it: Big Bass Bonanza Megaways delivers the best of both worlds — the charm of the original with the firepower of Megaways. It’s fast, punchy, and offers enough depth to satisfy experienced slots players while still being easy to grasp for newcomers. If you want the biggest version of Big Bass with more ways to win than ever, this is the one to play. And where better to spin it than MrQ Casino, one of the best UK online casinos for Pragmatic Play slots?

4. Big Bass Crash

• Type: Crash game
• RTP: 95.50%
• Max Multiplier: Up to 5,000x

Not a slot, but a crash game. Place your bet, watch the multiplier rise, and cash out before the net breaks. Autobet and 50% cashout features add strategy.

Why we like it: Fresh twist for fans of crash games, with the Big Bass charm still intact.

The Big Bass series has never been afraid to reinvent itself, but with Big Bass Crash, Pragmatic Play throws out the reels entirely and dives headfirst into the crash-game craze. Forget paylines and spinning symbols — this is a game about risk, timing, and knowing when to cash out. It’s bold, fresh, and easily one of the best MrQ slots for UK players looking for something different in 2025.

At its core, Big Bass Crash is beautifully simple. You place your bet, the fisherman casts his net, and the multiplier starts climbing. Each passing second pushes the multiplier higher, and the tension builds with it. Do you cash out at 2x for a safe win? Hold on until 10x and risk it all for a bigger payday? Or do you shoot for the moon and pray the net doesn’t snap? The crash can come at any moment, and when it does, the round ends.

Visually, this isn’t a flashy slot. Instead, it leans into clean, minimalist graphics with the fisherman and his trusty net at the heart of the screen. It feels more arcade than casino, and that’s the point — it’s about gameplay tension rather than visual excess. Still, Pragmatic Play adds subtle flourishes like fish darting across the waterline and smooth animations that give the game polish and character.

What makes Big Bass Crash shine are its features built for strategy. The 50% Cash Out option lets you hedge your bets, banking half your winnings while keeping the rest in play. Autobet and Auto Cash Out tools add another layer, letting you set a target multiplier and play with discipline rather than instinct. And for data-hungry players, the statistics panel is a gift — showing up to the last 500 rounds so you can study patterns, spot streaks, or convince yourself to hold your nerve a little longer.

The RTP sits at 95.5%, slightly lower than traditional Big Bass slots, but that’s expected with crash mechanics. The volatility is high, meaning streaks of small wins punctuated by massive multipliers if you hold your line. It’s not for the faint-hearted, but that’s what makes it so addictive.

Why we like it: Big Bass Crash takes everything that makes crash games popular — simplicity, tension, and massive win potential — and injects it with Big Bass personality. For UK players, it’s a refreshing break from reels without losing the excitement of chasing a big catch. Add in smart features like 50% Cash Out and Autobet, and it becomes a perfect pick-up-and-play option. And if you’re looking for where to try it, MrQ Casino is one of the best UK sites for Big Bass Crash, offering smooth gameplay, instant payouts, and a line-up of Pragmatic Play favourites to keep you hooked.

5. Big Bass Keeping It Reel

• Reels/Paylines: 5 reels, 10 paylines
• RTP: 96.07%
• Max Win: 10,000x
• Volatility: High

Adds a “Golden Net” feature where uncollected fish values stack and can be claimed with Golden Wilds. Each Wild retriggers free spins and boosts multipliers.

What’s good? The Net Collect mechanic keeps every spin exciting. Great for players chasing bigger volatility.

When Pragmatic Play named this one Big Bass Keeping It Reel, they weren’t joking. This slot takes the familiar fishing formula and adds a clever new twist: a feature net that collects every unclaimed fish. The result? A game that feels familiar but still manages to keep things fresh for even the most seasoned slot anglers.

At first glance, it’s classic Big Bass territory. The fisherman’s back, the reels are filled with rods, tackle, dragonflies, and those ever-present money fish. You’ve got a standard 5×3 reel setup and 10 paylines, but under the surface, there’s a lot more going on.

The headline feature here is the Golden Net mechanic. Every time a fish symbol lands without being collected by a Wild, it doesn’t just vanish — it gets stored in the net. That net sits teasingly on the side of the reels, growing bigger with every missed catch. Then comes the Golden Wild, a rare but beautiful sight. When it lands, it scoops up the lot, awarding you the entire value of the net in one big haul. The catch? Fish are slippery. At the start of each spin, one of them can wriggle free and knock some value off the net. It’s a brilliant risk-reward mechanic that adds an extra layer of tension to every spin.

Free spins are here too, triggered by the trusty scatter. You’ll start with up to 20 spins, and during the bonus round, fish symbols carry cash values just like always. Wilds collect them instantly, and every fourth Wild retriggers the feature with extra spins and multipliers of up to 10x. Combine that with the Golden Net and you’ve got some seriously juicy potential on the table.

Visually, Keeping It Reel looks the part. Bright waters, crisp animations, and that cheeky fisherman grinning as you rack up wins. It has a polished, cartoony charm that matches its light-hearted fishing theme. The soundtrack is chilled but upbeat — think lazy summer afternoons by the water, only with thousands of pounds potentially on the line.

The RTP is set at 96.07% with high volatility, so expect stretches of quiet reels punctuated by big splashes when the net pays out or multipliers kick in. It’s the sort of game designed for players who like a bit of suspense and are happy to wait for those high-impact wins.

Why we like it: Big Bass Keeping It Reel is more than just another sequel. The Golden Net mechanic is a clever addition that keeps every spin interesting, while the free spins and retriggers make sure the big wins are still there for the taking. It’s a smart evolution of the Big Bass formula and proof that this series still has plenty of bite left.

6. Big Bass Bonanza Amazon Xtreme

• Reels/Paylines: 5 reels, 10 paylines
• RTP: 96.07%
• Max Win: 10,000x
• Volatility: High

Set in the Amazon, this version introduces the Pot Pick feature before free spins. Pick modifiers like guaranteed fish, extra Wilds, or multipliers up to 50x.

What’s Good?: The Pot Pick adds strategy and unpredictability, making it one of the most engaging versions.

Just when you thought the Big Bass series had covered every fishing hole worth casting a line into, Pragmatic Play takes us deeper — into the wilds of the Amazon. Big Bass Bonanza Amazon Xtreme doesn’t just bring a fresh backdrop, it introduces new mechanics, higher volatility, and a whole lot more drama. It’s the jungle expedition of the Big Bass universe, and if you’re a UK slots player looking for adrenaline-packed gameplay, this one’s right at the top of the list.

The setup is instantly recognisable: 5 reels, 3 rows, and 10 paylines. But the jungle theme sets a different tone. Vivid greens, exotic birds, and flowing river animations replace the coastal calm of earlier titles. The soundtrack is more adventurous too — jungle drums and atmospheric effects keep you on edge as you spin. This isn’t a lazy day on the water; it’s a full-on expedition.

The big twist comes with the Pot Pick feature before free spins. Land 3 or more scatters and you’ll be asked to pick from a series of pots. Each pot contains a bonus modifier, from guaranteed Money symbols to extra free spins, starting Wilds on the progressive trail, or even the removal of the lowest-value fish. The suspense here is brilliant — you’re setting up your free spins adventure before it even begins, and those modifiers can make all the difference.

Once free spins kick off, it’s classic Big Bass chaos but with extra teeth. Wild Fishermen collect Money symbols as usual, and every 4th Wild retriggers the feature with more spins and higher multipliers — climbing all the way up to a massive 50x. The Waterfall feature can also trigger at random, flooding the reels with fresh Money symbols when you least expect it. Add that to the modifiers from the Pot Pick and you’ve got one of the most dynamic bonus rounds in the series.

The volatility here is high, and the RTP sits at 96.07%, which feels about right given the swings. You’re not going to see constant small payouts, but when things align, Amazon Xtreme can deliver some jaw-dropping hits. It’s a slot for players who like tension, risk, and the thrill of going big.

For UK players, MrQ Casino is one of the best places to play Big Bass Bonanza Amazon Xtreme. Not only do they have the full Big Bass series lined up, but they also back it with free spins offers and regular promotions that fit perfectly with high-volatility slots like this one. If you’re hunting for the best Big Bass slots at MrQ, Amazon Xtreme should be one of your first stops.

Why we like it: Big Bass Bonanza Amazon Xtreme elevates the formula with jungle visuals, smart modifiers, and extreme multipliers that can reach 50x. It’s more volatile, more suspenseful, and more rewarding than most sequels, and at MrQ, it’s one of the standout fishing slots you’ll want to reel in.

7. Big Bass Xmas Xtreme

• Reels/Paylines: 5 reels, 10 paylines
• RTP: 96.07%
• Max Win: 10,000x
• Volatility: High

Festive edition with snowy graphics, penguin symbols, and Christmas bonuses. Modifiers during free spins include guaranteed fish, multipliers up to 50x, and random waterfall reels.

Why we like it: Seasonal fun with serious win potential. Great for December spins, but still works year-round.

Every year, slot developers roll out festive editions of their most popular titles. Some feel like quick reskins, while others genuinely add to the experience. Big Bass Xmas Xtreme, Pragmatic Play’s seasonal spin on their fishing phenomenon, is definitely the latter. This isn’t just Big Bass with a dusting of snow — it’s a fully fleshed-out holiday edition with extra features, multipliers, and that festive sparkle.

The first thing you’ll notice is the art direction. The reels are frozen in a shimmering lake, with frosty edges, snow-topped trees in the background, and even a bundled-up fisherman in his winter coat. Classic Big Bass symbols like the fishing rod, tackle box, and float are here, but they’re joined by holiday extras like ornaments and a penguin wrapped in Christmas lights. It’s bright, colourful, and instantly gets you into the festive spirit.

Gameplay sticks to the trusted 5 reels, 10 paylines format, but Big Bass Xmas Xtreme packs in more volatility than usual. At its core, it’s about Money symbols (fish) combined with Wild Fishermen, who collect all cash values in view. But here, modifiers push things further. Land 3 or more Scatters, and you’ll trigger Free Spins. Before the round begins, you’ll get a Pick a Box feature, where you choose presents to reveal bonuses — guaranteed fish, extra spins, or even pre-collected Wilds on the progressive trail.

Once inside Free Spins, multipliers escalate. Each set of 4 Wilds collected retriggers the round and pushes the multiplier higher, all the way to a jaw-dropping 50x on the eighth retrigger. That’s far more extreme than the standard Big Bass titles and really justifies the “Xtreme” in the name. Add in features like the Waterfall, which can flood the screen with fresh Money symbols, and every spin feels loaded with potential.

RTP sits at 96.07%, and the high volatility means it won’t always be consistent, but the thrill of hitting those stacked multipliers makes this one of the most exciting Big Bass entries to date. And because it’s a holiday edition, it works just as well in December as it does in July — the design holds up year-round.

For UK players, MrQ Casino is a brilliant place to play Big Bass Xmas Xtreme. Not only do they offer regular free spins bonuses that can be used on Big Bass slots, but their selection of Pragmatic Play titles is second to none. It’s one of the best MrQ slots for players who want volatility with festive charm.

And if you’re chasing the festive theme beyond slots, don’t forget that some of the best scratch cards at Giant Lottos also offer that same instant-win buzz with a holiday twist. Mixing the thrill of online scratch cards with the power of high-volatility slots is a smart way to diversify your play this season.

Why we like it: Big Bass Xmas Xtreme is more than just a holiday rebrand — it’s the ultimate festive fishing slot with stacked modifiers, a progressive multiplier trail up to 50x, and enough charm to last beyond Christmas.

8. Big Bass Mission Fishin’

• Reels/Paylines: 5 reels, 10 paylines
• RTP: 96.5%
• Max Win: 5,000x
• Volatility: High

Adds choice: when triggering the bonus, pick between Free Spins or Stack the Cash. Both feature multipliers, cash collects, and Fisherman Wilds.

What’s Good?: Player choice adds variety, keeping the bonus rounds fresh.

Pragmatic Play have proven time and again that they know how to keep a hit slot series fresh. Big Bass Mission Fishin’is one of the boldest entries yet, taking the familiar fishing formula and cranking it up with a brand-new set of bonus mechanics. It’s not just a reskin or a festive variant — this is a title that feels like it belongs in the future of the Big Bass franchise.

Visually, Mission Fishin’ nails the atmosphere. You’re plunged into shimmering blue depths, with bubbles rising past symbols that include dragonflies, fishing gear, and the all-important Fisherman. There’s even a hint of sci-fi with robo-crabs and golden fish coins making appearances. The soundtrack adds to the tension, with reels bubbling like sonar pings before rewarding hits.

The action is built on a 5×3 grid with 10 paylines and a respectable 96.5% RTP. It’s high volatility, which is exactly what fans of the series expect. But where Mission Fishin’ goes further is in its Bonus Choice mechanic. Trigger Free Spins by landing 3 or more Scatters and you’re given a decision: play the classic Free Spins mode, or opt for the Stack the Cash Bonus.

Free Spins bring back the Fisherman Wild, who collects all visible Fish Money values. Every 4 Wilds retriggers the feature, handing out 10 more spins and a boosted multiplier up to 10x. Meanwhile, the alternative Stack the Cash Bonus adds a fresh layer of risk and reward, as you watch Money symbols build into massive totals. The choice gives players genuine agency — do you stick with a proven formula or take the chance on something even more volatile?

The symbols carry solid payouts, with fishing rods and tackle boxes paying up to £100 and £50 respectively (based on a £1 stake). Combine those with the Money symbol mechanic and you’re looking at wins up to 5,000x your stake if the bonus features fall into place.

For UK players, this game really shines at MrQ Casino. Pragmatic Play titles run seamlessly here, and with MrQ’s clean, ad-free platform it’s easy to focus on the fishing action without distraction. It’s no exaggeration to call Mission Fishin’ one of the best MrQ slots in the UK right now — especially if you like volatility and features that feel more interactive than your average slot.

And if you’re the kind of player who enjoys variety, don’t stop at slots. Many of our readers also enjoy exploring some of the best UK lottery sites to balance long-term jackpot dreams with fast-paced spins. Mixing both gives you the best of both worlds — instant wins from slots, and the life-changing potential of a lottery ticket.

Why we like it: Mission Fishin’ introduces genuine player choice into the Big Bass formula. Whether you go Free Spins or Stack the Cash, there’s more strategy here than ever before. Add in a slick design and the huge win potential, and it’s a must-play for any fan of high-volatility slots.

9. Big Bass Hold & Spinner

• Reels/Paylines: 5 reels, 10 paylines
• RTP: 96.07%
• Max Win: 10,000x
• Volatility: High

Introduces the Hold & Spinner mechanic. Land 3 Money symbols to lock them in and respin for more. Each new symbol resets spins and boosts prizes.

What’s Good: Combines Big Bass classics with Hold & Spinner for an exciting hybrid.

Every once in a while, Pragmatic Play shake up the formula of their flagship fishing series, and Big Bass Bonanza Hold & Spinner is one of those moments. It keeps the DNA of the original Big Bass Bonanza intact — 5 reels, 10 paylines, money symbols, and the trusty Fisherman Wild — but introduces a Hold & Spinner feature that changes how the bonus game plays out. The result? A slot that feels both familiar and refreshingly new.

At first glance, Hold & Spinner doesn’t mess too much with the visuals. The reels are still set against that bright blue underwater backdrop, with dragonflies, fishing rods, tackle boxes and fish swimming across the reels. The music and sound effects are upbeat, creating the same sense of excitement as the original Bonanza. But it’s in the features where this title makes its mark.

The free spins mode is activated by landing 3 or more Scatters, with up to 20 spins on offer. This is where the Fisherman Wild comes into play, collecting all visible Cash symbol values as instant prizes. Every Wild is also collected into the Wild retrigger trail. For every 4th Wild collected, you gain 10 more spins and a bigger multiplier, climbing from 2x to 3x, and eventually up to 10x. That means free spins can last far longer than you expect, especially when luck is on your side.

The new twist is the Hold & Spinner bonus game. Land 3 or more Money symbols and you’ll trigger this round, with each Money symbol locking in place. You start with 3 respins, and every new symbol resets the counter back to 3. Each Money symbol carries a cash value of up to 2,000x your stake — and when the round ends, all of them are combined for a potentially huge payout. This feature is where Hold & Spinner truly earns its name, and it’s a cracking addition for players who love high-risk, high-reward gameplay.

In terms of payouts, the slot can deliver up to 10,000x your stake at its peak, which is enough to satisfy even the most seasoned slot fans. Combined with a solid 96.07% RTP, it’s a game that feels rewarding but still packs that Big Bass volatility punch.

For UK players, this is easily one of the best Big Bass slots at MrQ. MrQ Casino has built a reputation for showcasing the most popular Pragmatic Play titles, and Hold & Spinner is right up there as a fan favourite. It’s fast, fun, and fits perfectly into the Big Bass series line-up available on MrQ’s platform.

And if you’re curious about the odds and excitement of different kinds of jackpots, don’t miss our feature on Omaze vs Lottery – your chances of winning. It’s the perfect companion piece to a game like Hold & Spinner, giving you insight into how online slots stack up against life-changing lotteries.

Why we like it: Hold & Spinner adds a brand-new bonus feature without losing what made the original so good. It’s fast-paced, it’s rewarding, and at MrQ it ranks as one of the best Big Bass slots you can play right now.

10. Big Bass Hold & Spinner Megaways

• Reels/Paylines: 6 reels, 117,649 paylines
• RTP: 96.70%
• Max Win: 20,000x
• Volatility: High

The Megaways version of Hold & Spinner. Adds cascading reels, extra bonus rows, and progressive multipliers up to 50x.

What’s Good?: The biggest win potential in the series — a true high-volatility slot for thrill-seekers.

If you thought the Big Bass series couldn’t get any bigger, Pragmatic Play has proved otherwise with Big Bass Hold & Spinner Megaways. This 2025 release takes the Hold & Spinner mechanic introduced in the original, throws in the Megaways system, and cranks everything up to eleven. The result? A slot that’s all about scale, volatility, and big payout potential.

The first thing that hits you is the grid. Gone are the fixed paylines of the early games. Here, you’ve got up to 117,649 Megaways in play, which means almost endless ways to line up wins. Every spin can expand or shrink the number of active rows, keeping gameplay unpredictable and electric. If you’ve already checked out our Megaways slots guide, you’ll know why this system is one of the most popular innovations in slot gaming. Pairing it with Big Bass was a masterstroke.

Visually, Hold & Spinner Megaways feels like a modern update to the familiar formula. The underwater backdrop returns, with slicker animations and crisper sound design. Each cascade is a rush — as winning combinations explode and new symbols drop in, it feels like your catch of the day might be right around the corner.

As for features, there’s plenty to dive into. The Hold & Spinner bonus remains the showpiece. Land 3 or more Coin symbols and you’ll trigger this round with sticky coins locking into place. You start with 4 respins, but every new Coin resets the counter. Each Coin can carry a value up to 2,000x your bet, and when the feature ends, all prizes are combined. With extra rows unlocking during the bonus, the potential for mega payouts is very real.

Then there’s the free spins mode, activated by 3 or more Scatters. During these spins, the Fisherman Wild becomes the Collect symbol, bagging all Money symbol values in view. Each Wild also adds to the progressive trail, granting extra spins and multipliers that scale up to 50x. Combined with the Megaways cascades, this creates an exhilarating balance of frequent small hits and the chance of monster wins.

Big Bass Hold & Spinner Megaways can pay up to 20,000x your stake with a strong 96.7% RTP, making it one of the most generous titles in the entire Big Bass line-up.

For UK players, this is easily one of the top MrQ slots of 2025. The casino has fully embraced the Big Bass franchise, and with Hold & Spinner Megaways available alongside fan favourites like Splash and Bonanza, MrQ is building one of the best collections of Pragmatic Play’s work anywhere online.

And if you’re a jackpot hunter, you’ll want to read our Play US Powerball in the UK guide. It’s the perfect complement to a game like this, showing how slot payouts compare to one of the world’s most famous lotteries.

Why we like it: Hold & Spinner Megaways takes everything fans love about the series and dials it up. More paylines, more multipliers, and more adrenaline — and as a 2025 MrQ highlight, it’s unmissable for Big Bass fans.

11. Big Bass Floats My Boat

• Reels/Paylines: 5 reels, 10 paylines
• RTP: 96.07%
• Max Win: 10,000x
• Volatility: High

Free spins introduce reel multipliers that increase every time a Money symbol lands. Fisherman Wilds collect values and apply multipliers.

What’s Good?: Multipliers on reel spaces make every spin count.

By now, the Big Bass series has proven it can adapt to just about any theme — cowboys, Christmas lakes, Amazon rivers — and with Big Bass Floats My Boat, Pragmatic Play sets the fisherman adrift on a new kind of adventure. The result? A fresh spin on a familiar formula, and one of the most enjoyable Big Bass games we’ve played in 2025.

This slot sticks to the traditional 5×3 reel layout with 10 paylines, but don’t let the simplicity fool you. Floats My Boat adds clever twists to keep even seasoned Big Bass fans engaged. The backdrop is a sunlit river cruise, complete with animated waters and that unmistakable ripple effect that Pragmatic Play nails so well. Every spin feels breezy, with crisp graphics and a clean UI that make it easy to focus on the action.

The real hook lies in its Money Symbol mechanics. Fish symbols appear with random cash values, and on any spin, they can all be instantly collected thanks to a random feature that sweeps the reels. Even better, those collections can come with a surprise multiplier — up to 50x. It means you’re never just spinning for standard line wins; there’s always the sense that something big could trigger at any moment.

Land 3 or more Scatters and you’ll hit the Free Spins feature, where Floats My Boat really shines. Here, every reel space starts with a 1x multiplier that increases each time a Money symbol lands in that position. Stack this with the Fisherman Wild, which collects all Money symbol values and applies the space multiplier, and suddenly the game becomes a high-octane multiplier machine. Add in the progressive Wild trail — where every 4 Wilds collected adds extra spins — and it’s easy to see why this slot has quickly become a favourite.

With a 96.07% RTP and max win potential of up to 10,000x your bet, Floats My Boat balances volatility and reward beautifully. It’s less chaotic than Megaways titles, but the layered mechanics give it surprising depth.

For UK casino players, this is exactly why sites like MrQ have become the go-to destination for slots. The best MrQ slots aren’t just the latest branded titles; they’re games like Floats My Boat that blend easy-to-follow gameplay with explosive bonus features. MrQ has stacked its catalogue with Big Bass games for this reason — they’re proven fan favourites, and Floats My Boat is no exception.

And if you’re a jackpot chaser who likes your stakes even bigger, don’t miss our guide to the Mega Millions lottery. Comparing multi-million jackpots to slot max wins gives you perspective on just how big the swing for glory can be.

Why we like it: Floats My Boat isn’t just another fishing slot. It feels smoother, sharper, and more rewarding than many of its predecessors, making it one of the standout Big Bass titles in the MrQ library for 2025.

12. Big Bass Day at the Races

• Reels/Paylines: 5 reels, 10 paylines
• RTP: 96.07%
• Max Win: 10,000x
• Volatility: High

Themed around horse racing. Money symbols can be collected randomly with multipliers up to 50x. Free spins include bonus picks for guaranteed fish or extra Wilds.

What’s Good?: Quirky racing theme with strong multipliers and bonus picks.

The Big Bass series has always been about fishing rods, lures, and a trusty boat. But Big Bass Day at the Races rips up the tackle box and takes the fisherman somewhere unexpected — the racetrack. Pragmatic Play swaps bass for thoroughbreds, and it works better than you’d expect. It’s proof that the Big Bass formula can stretch far beyond the shoreline while still delivering those signature cash collect thrills.

The setup is familiar: a 5×3 reel layout with 10 paylines and an RTP of 96.07%. On the surface, the reels look clean, with champagne bottles, binoculars, and horse racing symbols providing a new theme for long-time fans. The animations are playful, with bursts of celebration when wins land, and the background hum of race day energy replaces the usual gentle water flow. Pragmatic Play has clearly had fun with the visuals here, and it shows.

The game introduces a clever Money Collect feature that keeps the tension high. During any base spin, Money symbols can land with cash values. Then, out of nowhere, a random trigger can activate, collecting all visible Money symbols and applying an extra multiplier up to 50x. It’s this unpredictability that makes each spin feel like the equivalent of backing a long-shot horse — there’s always the chance of something spectacular happening.

But it’s the Free Spins Bonus Picks that really elevate Day at the Races. Land 3 or more Scatters, and before free spins begin, you’ll pick from a selection of horses. These picks reveal modifiers such as additional free spins, guaranteed Money symbols, or extra Wilds already added to the progressive trail. It’s a neat pre-bonus layer that gives players a sense of control and adds genuine replay value.

Once free spins are underway, the real Big Bass DNA shines through. Fisherman Wilds transform into Collect symbols that bag all visible Money symbol values, while also pushing the progressive trail forward. Every few Wilds collected add more spins and multipliers — up to 50x. With the potential for cascading boosts and juicy Money values, the free spins round has the kind of high-volatility punch the series is famous for.

The max win is capped at 10,000x your bet, which puts it comfortably alongside the heaviest hitters in the series. Combined with its crisp race-day aesthetic and unique modifiers, this slot doesn’t feel like a lazy reskin. Instead, it’s a fresh theme that proves Pragmatic Play knows how to keep their flagship series relevant.

Why we like it: Big Bass Day at the Races blends the thrill of racing with the proven Big Bass formula. The pre-bonus picks add genuine strategy, while multipliers up to 50x keep the action high-stakes. It’s a surprising twist that pays off.

13. Big Bass Vegas Double Down Deluxe

• Reels/Paylines: 5 reels, 10 paylines
• RTP: 96.5%
• Max Win: 5,000x
• Volatility: High

Neon Vegas makeover with red and blue Wilds tracked separately. Each retrigger boosts multipliers up to 10x.

What’s Good?: Unique style with dual Wilds and strong retrigger potential.

The Big Bass fisherman has swapped quiet lakeside waters for the bright, chaotic glow of Las Vegas. Big Bass Vegas Double Down Deluxe is Pragmatic Play’s boldest twist on the series yet, throwing its trademark fishing action onto the neon strip. It’s a clever crossover — part fishing trip, part casino night — and it captures the vibe of Sin City perfectly.

The slot keeps the classic 5×3 reel setup with 10 paylines, but the design is pure Vegas. Neon fish symbols glow in hot pinks and electric blues. Flamingos, tackle, and rods shimmer under casino-style lighting. It’s flashy, playful, and immediately stands out from other entries in the Big Bass collection. That alone makes it one of the best Big Bass casino games for players who want something that feels familiar but still fresh.

Gameplay stays true to the series. Money symbols carry random cash values and, when collected by a Fisherman Wild, they pay out instantly. During the base game, special features like the Bazooka, Hook, and Dynamite modifiers can trigger. These shake up the reels by pulling in more Fishermen, adding extra fish, or blasting away symbols for a brand-new spin. It’s chaotic fun, and in Vegas-style fashion, everything feels bigger and louder here.

The real magic happens in the Free Spins round, unlocked by landing 3 or more Scatters. You’ll start with 10, 15, or 25 free spins depending on how many Scatters hit. During this mode, blue and red Wild Fishermen appear, each collected on their own progress bar. Every fourth Fisherman retriggers the feature, adding 10 more spins and a multiplier — 2x, 3x, or up to 10x — to Money symbol collections. It’s a clever twist that doubles the excitement, because you’re chasing two different progress tracks at once.

With an RTP of 96.5% and a max win of 5,000x your bet, this slot carries the high volatility punch you’d expect. It’s unpredictable, but when the multipliers align, Vegas Deluxe can deliver massive, adrenaline-charged payouts.

For UK players, this one shines as part of the growing catalogue of MrQ online slots. The mix of immersive visuals, bonus-packed features, and the proven Big Bass formula makes it stand out even among heavy hitters.

Why we like it: Big Bass Vegas Double Down Deluxe delivers the perfect blend of fishing fun and Vegas spectacle. The twin Wild meter system adds depth to free spins, and the neon visuals make it one of the most striking entries in the series. A must-play for fans chasing both style and substance.

14. Big Bass Secrets of the Golden Lake

• Reels/Paylines: 5 reels, 10 paylines
• RTP: 96.07%
• Max Win: 10,000x
• Volatility: High

Free spins split into Standard or Golden Lake mode. Golden Lake spins feature only Fish and Fisherman symbols for intense volatility.

What’s Good?: The Golden Lake bonus is pure adrenaline — just Fish and Wilds for max action.

The Big Bass fisherman has seen it all — icy lakes, Amazon rivers, even neon Vegas waters. But with Big Bass Secrets of the Golden Lake, Pragmatic Play takes things to a whole new level. This is fishing with a golden twist, offering players a shot at some of the most rewarding features in the series to date.

Visually, Secrets of the Golden Lake is a step up. The reels shimmer with golden accents, and beneath the calm blue water lies a treasure chest’s worth of sparkling fish. The familiar dragonfly, rod, and bait symbols return, but here they look richer and more refined. This subtle polish makes the slot feel like a premium entry in the series — a game that knows it’s special.

At its core, this is still a 5×3 slot with 10 paylines and an RTP of 96.07%, but it comes with a standout twist: the Golden Lake Free Spins mode. Land 3 or more Scatters to unlock free spins, but instead of diving straight in, you pick from a set of cards. Most will reveal standard free spins, but some reveal the coveted Golden Lake Spins. This upgrade removes regular paytable symbols entirely, leaving only Fish and Fishermen on the reels. That means every spin has real potential — no wasted lines, no filler symbols, just pure cash-collecting action.

Even in the standard Free Spins round, the familiar Big Bass progression mechanic is present. Fisherman Wilds collect all visible Fish values and are stored on a progressive trail. Every fourth Fisherman retriggers the round, awarding an extra 10 free spins and upgrading the multiplier — 2x, 3x, and up to 10x. In Golden Lake mode, it gets even better: with fewer symbols, the chance of landing Fisherman + Fish combos skyrockets, and the retrigger system makes those spins snowball into serious payouts.

With a maximum win of 5,000x your bet, this slot balances high volatility with enough bonus variety to keep the gameplay tense but rewarding. The design of the Golden Lake mode makes it one of the most exciting iterations of the Big Bass formula yet.

For UK slots players, this one sits comfortably among the best big bass slots to play at MrQ Casino. It’s the mix of innovative features and familiar mechanics that makes it shine. MrQ is already well-known for its strong lineup of Big Bass titles, but Secrets of the Golden Lake adds that extra prestige — the feeling of chasing something rare and exclusive.

Why we like it: Secrets of the Golden Lake is Big Bass with the volume turned up. The card-pick mechanic adds suspense, the Golden Lake upgrade keeps spins tight and focused, and the progressive multipliers ensure big-win potential. It’s a golden addition to the series — and one that deserves a place on your playlist.

15. Big Bass Q The Splash (Exclusive to MrQ)

• Reels/Paylines: 5 reels, 10 paylines

• Max Win: 5,000x
• Volatility: High

An exclusive MrQ version of Big Bass Splash. Branded symbols, extra modifiers, and unique bonus visuals.

What’s Good?: Exclusive to MrQ Casino, making it a must-play if you’re looking for the best MrQ slots in 2025.

Pragmatic Play’s Big Bass Q The Splash is something special. It’s not just another entry in the fishing-themed slot series — it’s an exclusive title you can only play at MrQ. That exclusivity alone makes it one of the most talked-about slot launches for UK players in 2025.

From the moment the reels load, you know this game is different. The familiar underwater backdrop is here, but with a MrQ twist. The symbols — from trucks to fish — proudly display the MrQ logo, and even the fisherman’s shirt pocket is branded. It’s a clever touch that immediately marks this as a one-of-a-kind slot. Add in the animated bubbles, swimming fish, and upbeat soundtrack, and you’re immersed in a colourful, ocean-themed world that feels both familiar and fresh.

Gameplay & Features
Big Bass Q The Splash uses the classic 5×3 reel setup with 10 paylines and a generous 96.71% RTP. At first glance, it mirrors Big Bass Splash, but a closer look reveals plenty of extras. Landing 3 or more MrQ Scatter symbols triggers the Free Spins feature, where modifiers add layers of excitement. You could get extra spins, more Fish, or even additional Fishermen to boost your winning chances.

During the free spins, the Fisherman Wild symbol does its usual work by collecting all visible Money fish values. Every fourth Wild retriggers the bonus, giving you more spins and increasing multipliers up to 10x. And just when you think it’s over, features like Dynamite, Hooks, and Bazookas can trigger at random, pulling extra symbols onto the reels or blasting away duds to create new winning combinations.

Why Play It at MrQ?
This is where things get exciting for UK players. Because Big Bass Q The Splash is exclusive to MrQ, it’s not just about the game itself, but also the value MrQ adds.

16. Big Bass Bonanza 3 Reeler

• Reels/Paylines: 3 reels, 5 paylines
• RTP: 96.5%
• Max Win: 5,000x
• Volatility: Medium-High

A stripped-down, retro version of Big Bass. Classic 3-reel design with Scatters triggering free spins. Fisherman Wilds still collect fish values.

What’s Good?: Old-school format with modern Big Bass features. Perfect for fans of traditional slots.

The Big Bass series is known for variety, and Big Bass Bonanza 3 Reeler proves that bigger isn’t always better. Instead of sprawling Megaways grids or endless modifiers, Pragmatic Play strips things down to a classic 3-reel format with 5 paylines. It’s a refreshing throwback that captures the nostalgic charm of old-school slots while keeping the signature Big Bass features intact.

Graphics & Atmosphere

The visuals are sleek and simple, perfectly matched to the smaller grid. You still get the bubbling reels, shimmering surface water, and the fish swimming in the background. The soundtrack has a light, playful quality, echoing the fun of retro slot machines but with the modern polish we expect from Pragmatic Play. It feels cosy — like playing a traditional slot in a seaside arcade, only with far bigger payouts on the line.

Gameplay & Features

Don’t let the minimal reels fool you — there’s still plenty happening under the surface. Big Bass Bonanza 3 Reelercarries an impressive 96.5% RTP and a maximum win of 5,000x your stake, putting it right up there with the best Big Bass online slots for payout potential.

The big draw here is the Free Spins round, triggered by landing 3 Scatter fish. Once activated, the familiar Fisherman Wild joins the action, collecting Money fish values just like in the other games in the series. Collect four Fishermen and you retrigger the feature, unlocking more spins and multipliers up to 10x.

Even in the base game, the random hook, dynamite, and bazooka features can spice things up, pulling in new Scatters or transforming reels when you least expect it. These surprises keep the gameplay lively despite the pared-back grid.

Why Play It

Big Bass Bonanza 3 Reeler is proof that Pragmatic Play knows how to innovate without overcomplicating things.
