Big Bass Splash Demo and Review

Big Bass Splash Slot Review

Released in June 2022, Big Bass Splash is a high-volatility, fishing-themed slot developed by Reel Kingdom and published by Pragmatic Play. It’s the fourth entry in the Big Bass series and carries the highest maximum win in the catalogue at 5,000x, compared to the original Big Bass Bonanza's 2,100x. Random modifiers give each free spins session its own unique identity, a good reason as any to play this over its predecessors.

Reel Kingdom, the studio behind the Big Bass series, consistently keeps each new entry easy to pick up while adding enough variation for it to feel one-of-a-kind. This is ideal for returning players who wish to stay on theme but are looking for something new.

Big Bass Splash Gameplay

Big Bass Splash has a steady base game, occasionally lifted by its bonus features, which is exactly what you’d expect from a slot with a high volatility rating and an above-average RTP. Payouts vary considerably in size, with longer stretches between wins a regular part of the experience.

The minimum bet per spin is £0.10, making Big Bass Splash accessible for a wide range of budgets.

Here's what you can expect to win for each symbol based on a £1 stake:

Symbol	2 on a payline	3 on a payline	4 on a payline	5 on a payline
Monster Truck (high)	£0.50	£5.00	£20.00	£200.00
Fishing Rod (high)	-	£3.00	£15.00	£100.00
Dragonfly (high)	-	£2.00	£10.00	£50.00
Tackle Box (high)	-	£2.00	£10.00	£50.00
Fish (Money symbol)	-	£1.00	£5.00	£20.00
Ace / King (low)	-	£0.20	£2.50	£10.00
Queen / Jack / Ten (low)	-	£0.20	£1.00	£5.00

The jump from three to five of a kind is noticeable throughout the table, which makes landing a full set feel more worthwhile. It also means three-of-a-kind hits in the base game rarely feel as rewarding, but still keep the session ticking along.

Theme and Story of the Big Bass Splash Slot

Big Bass Splash is played just below the water's surface, looking up towards a sunlit shoreline visible at the top of the screen. Coral, seaweed, and rising bubbles frame the reels throughout, and the whole setting has a warm, relaxed feel.

The symbol range is easy to read from the first spin. Card symbols at the lower end – topping out at £5.00 for five of a kind – barely scratch the surface against a £50 session budget, while the premium fishing symbols are where the real returns sit, with five Monster Trucks paying out £200.00 at a £1 stake.

Graphics, Sounds and Vibes

Reel Kingdom has built a consistent visual identity across the Big Bass series, and Big Bass Splash is its most refined entry into the catalogue. The turquoise underwater setting and warm, sunlit colour palette make the reels immediately inviting, and the crisp, cartoon-style symbols stand out clearly against the gently animated backdrop. The soundtrack is bubbly and light, built around a bouncy melody with a tropical feel that sets the outdoor adventure tone from the first spin.

When the Fisherman Wild appears during Free Spins, the catch animation fires up – his rod swings, the fish pulls against the line, and the collected value flashes up on screen in a way that makes every collection feel more impactful. When the Free Spins round triggers, the music lifts noticeably in pace, turning into more of a country jig anthem. Likewise, the reels feel sharper and more alert during this stage, making it clear you’ve triggered the bonus, without pulling you into a completely unfamiliar and confusing setting (which some slots are prone to).

I asked one of CasinoTopsOnline's top gaming experts to weigh in on Big Bass Splash's soundtrack and visuals. Here's what they had to say:

Big Bass Splash Slot on Mobile

Big Bass Splash slot has been optimised to run seamlessly on all devices, whether you're at home or playing on the go. It's playable in both portrait and landscape mode, but I’d say portrait is the more user-friendly of the two for this slot.

Many slots tend to arrange the layout in portrait mode to keep everything accessible, and Big Bass Splash does this well. The controls are easy to reach while the reels take up most of the screen, meaning you still have a clean view of each spin. Landscape gives the underwater backdrop more room and feels closer to the desktop experience, but the controls spread out as a result, making one-handed play less comfortable.

Below, another CasinoTopsOnline writer elaborated on their experience of using Big Bass Splash for mobile:

Big Bass Splash Slot Bonus Features

Big Bass Splash has fewer features than many other Pragmatic Play titles, but each one feeds into the same central mechanic and can produce potentially rewarding results, provided the conditions line up.

Money Fish Symbols

The Fish symbol does far more than pay standard line wins. During the Free Spins round, every Fish on the reels also carries a randomly assigned Money value, ranging from 2x to 5,000x your total bet. When the Fisherman Wild is triggered, those values are collected and paid out instantly as cash. If you have a higher progression multiplier running, even a modest Fish value can turn into a decent payout.

Random Modifiers: Dynamite, Hook, and Bazooka

For the Fisherman to collect these symbols, he needs Fish symbols on the same spin. These three features fire randomly when one appears on the reels without the other, giving a spin that would otherwise pay nothing a second chance. The Dynamite drops Fish symbols onto the reels when a Fisherman has landed, but when no Fish are present.

The Hook pulls a Fisherman Wild onto the reels when Fish are there, but no Wild has appeared. The Bazooka fires when a Fisherman is on screen but no Fish have appeared, clearing every other symbol from the reels and redrawing them from scratch.

If only two Scatters land, a random second-chance mechanic can kick in, meaning either the existing Scatters nudge down the reels while the remaining reels respin, or a hook animation pulls a new Scatter into view for another shot at triggering the feature. Before the round begins, up to five modifiers are randomly selected: MORE FISH, MORE FISHERMAN, a Level 2 Start, +2 Spins, and MORE DYNAMITE, Hooks and Bazookas.

Every fourth Fisherman Wild collected retriggers the round, adding 10 extra spins and stepping the collection multiplier up to 2x at level 2, 3x at level 3, and 10x at level 4. Keep in mind, the feature ends immediately if the total win reaches 5,000x, but the chances of this happening are very slim.

Here's the opinion of one of CasinoTopsOnline's expert writers when it comes to the bonus features:

Big Bass Splash Slot Wagering Details

Understanding the maths is the best starting point for a player getting started with a new title. Big Bass Splash is a high volatility slot with an above-average RTP of 96.71%, and knowing what those two figures mean together will determine whether this slot suits your budget and playing style.

RTP and Volatility

A slot's volatility controls how its payouts are shaped across a session. Games at the lower end pay out smaller amounts more regularly. At the high volatility end (where Big Bass Splash sits), those smaller wins thin out, and the payout potential concentrates into fewer, but possibly bigger moments. Be aware that the volatility of this slot can eat through a budget quickly without the right approach.

At 96.71%, the Big Bass Splash RTP sits above the UK industry average of 96%, so I'd recommend it to most players on that basis. Some operators run reduced configurations at 95.67% or 94.60%, so it is worth checking the paytable at your preferred casino before you start. Slot Tracker puts the base game hit frequency at 13.4%, or roughly one win in every seven and a half spins, which sits fairly average when compared to other high volatility slots on the market.

Bet Sizes and Variance

The minimum bet size is £0.10, making Big Bass Splash one of the more accessible high volatility options on the UK market. The slot best suits players who can afford to wait for the bonus round rather than those looking for a quick session on a tight budget, making it a better choice for high rollers.

Jackpots and Best Wins

Big Bass Splash has no fixed or progressive jackpot mechanic, meaning the maximum win is fixed at 5,000x your stake. This is modest compared to fishing slot alternatives such as Fishin’ Frenzy: The Big Catch’s 50,000x ceiling. According to Slot Tracker, the highest recorded community win stands at 2,034.6x at the time of writing.

Bonus Frequency

Slot Tracker community figures place the real-world rate bonus frequency rate at 1 in 134, which isn’t too bad for a high-volatility slot. For context, comparable high-volatility titles like Nolimit City's Breakout average 1 in 250, so Big Bass Splash is considerably more generous on that front.

Testing the Big Bass Splash Slot with a £50 Bankroll

I used the Big Bass Splash demo featured at the top of this review to run a hypothetical £50 session, playing 100 spins at £0.50 each to see how the slot actually behaves in practice.

Until spin seven, I had no luck. Then, three Scatters landed and the modifier screen rolled out Level 2 and +2 Spins, giving me twelve free spins with the 2x multiplier active. Although the round was all in all quite dry, the Fisherman Wild collected modest Fish values with no retrigger, adding £8.50 net and nudging my balance briefly to £55.10.

After this, my balance slowly drained across the next 38 spins. Small wins landed here and there, but nothing of any significance, and by spin 45, I was back down to £40.45 with more than half the session left.

The second Free Spins trigger arrived with the same two modifiers. Fortunately, this one played out with more luck compared to the last. The Fisherman landed frequently and produced two Big Win moments in quick succession, first £9.50 then £10.25. The feature paid out £21.10 net, taking my balance up to £61.55. The final 55 spins produced no further triggers and I finished with a balance of £35.80.

Slot	Developer	RTP	Max Win	Theme	Bonus Features
Big Bass Splash	Reel Kingdom / Pragmatic Play	96.71%	5,000x	Fishing / underwater	Free Spins, Money Fish, Fisherman Wilds, Modifiers, Progression Meter
Fishin' Frenzy: The Big Catch	Blueprint Gaming	96.12%	50,000x	Fishing / outdoor	Free Spins, Fish Collection, Symbol Upgrade, Multipliers
Piranha Pays	Play'n GO	96.20%	5,000x	Underwater	Free Spins, Trail Collection, Win Multiplier, Mystery Instant Win
Amazing Catch	Just for the Win	96.08%	5,000x	Fishing	Money Symbols, Super Bonus Wheel, Free Spins, Multipliers

If chasing the biggest ceiling is your priority, then Fishin' Frenzy: The Big Catch is the standout pick, offering 50,000x at medium volatility and a lower entry point to potentially win big. On the other hand, if you’re a player who wants the best RTP and minimum bet combination, Big Bass Splash leads the group at 96.71% and £0.10 per spin, making it the most accessible of the four for longer sessions on a tight budget.

Does CasinoTopsOnline Recommend Big Bass Splash Slot?

Without a shadow of a doubt. Big Bass Splash is a fishing slot for players who are happy to ride out the quiet stretches, knowing that the bonuses have the potential to change their luck in an instant.

The random modifier draw and the Fisherman collecting high-value Fish across the reels are what set it apart from the rest of the Big Bass catalogue. It’s also player-friendly for those who still enjoy the simple design of the Big Bass series. No two free spins rounds feel the same, adding value to a longer session.
