The sequel bought its 5,000× ceiling out of the base game. Splash lets the multiplier fisherman land in ordinary play, which Big Bass Bonanza never did — and pays for it with longer gaps. Offshore the bonus buy costs around 100× stake; on UK sites it does not exist.

What Big Bass Splash actually is
The sequel raised the ceiling from 2,100× to 5,000× and let the multiplier fisherman appear during the base game.
How the UK version differs
Bonus buy is available offshore at roughly 100× the stake. It does not exist on any UK-licensed site.
Pragmatic ships this title in multiple configurations and picks per operator, exactly as it does with Bonanza — but the builds do not carry across between the two games. Two Pragmatic titles sitting side by side in the same lobby can be running different return settings. These band figures are reported by operators and slot databases and have not yet been confirmed against a studio document, so treat them as the shape of the spread rather than exact settings. Open each game's own information screen separately: how to read the paytable.
What the sequel actually changed
Two changes, and they are the same change viewed from either end.
The multiplier fisherman can now appear during the base game rather than only inside free spins, which is the headline feature and genuinely new to the family. And the ceiling moved from 2,100× to 5,000×.
Those are not two independent improvements. A slot's return is a fixed percentage, so a higher ceiling and a new base-game event both have to be paid for out of the same pot — and they are paid for by the ordinary rounds. The base game is quieter than Bonanza's, the gaps between anything interesting are longer, and the feature does more when it arrives.
The trade, stated plainly. Splash is not a better version of Bonanza. It is the same expected cost per spin arranged into a longer, flatter middle and a further-reaching tail. Which one suits you depends entirely on whether your bankroll can sit through the middle.
The fisherman in the base game
In Bonanza the multiplier only exists inside free spins and only climbs by retriggering. Splash lets a multiplier fisherman land in ordinary play, which changes the texture of the base round — there is now something that can happen outside the feature, rather than a pure wait for three scatters.
It also changes what a good session looks like. On Bonanza, essentially every meaningful result comes from a retriggered feature. On Splash a base-game sequence can produce a real win on its own, which is why the game reads as more volatile despite carrying the same headline return.
The catch is frequency. The event is rare enough that most base-game play still feels like waiting, and now the waiting is quieter than it was on the original because the return funding that new event came out of the small wins.
Who the higher ceiling is actually for
5,000× is more than twice Bonanza's 2,100×, and the number does a lot of marketing work. It is worth being precise about who benefits.
Reaching anywhere near a 5,000× outcome requires a deep feature with high money values at a high multiplier — an event most players will never see, at any stake, across years of play. Meanwhile the cost of funding that possibility is paid on every single spin by everyone, in the form of a thinner middle.
That makes Splash the right choice for a player deliberately buying a lottery ticket with a defined budget, and the wrong choice for a player trying to make a bankroll last. Bonanza's lower ceiling puts more of the same return into the rounds you will actually experience. The volatility explainer covers why this trade exists on every slot rather than being specific to this family.
The bonus buy at 100×, and the arithmetic
Offshore sites sell direct entry to the free spins round at roughly 100 times your stake — £200 on a £2 spin, £500 on a £5 one. UK-licensed sites have not offered feature buys since 2021.
The price is not arbitrary. A buy is priced so that its expected return is at or slightly below the game's ordinary return, which means buying in does not improve what you keep. It compresses time: you skip the quiet base game and go directly to the part of the machine that holds the variance.
On this title that compression is unusually severe, because the base game is deliberately quiet and the feature is where nearly everything lives. Buying a hundred features in a row at 100× stake is a fast, expensive way to sample the distribution — and it is the reason the buy sells better on Splash than on almost anything else in the lobby. Our bonus buy guide works through when a buy is and is not defensible.
Where Splash sits in the family
Reel Kingdom has built more variants of this brand than of anything else in modern slots. Splash is the high-ceiling entry; the others trade the same fixed return into different shapes.
| Version | Layout / engine | Max win | What actually changes |
|---|---|---|---|
| Big Bass Splash | 5×3, 10 paylines | 5,000× | This page. Multiplier fisherman can land in the base game — the family's only structural addition to ordinary play. |
| Big Bass Bonanza | 5×3, 10 paylines | 2,100× | The 2020 original. Multiplier only inside free spins. Steadier, and the better choice for a smaller bankroll. |
| Bigger Bass Bonanza | 5×4, 12 paylines | Varies | Taller grid and a different scatter count, so the feature arrives on a different rhythm. |
| Big Bass Bonanza Megaways | 6 reels, variable heights | Varies | Ways-based rather than payline-based. See Megaways slots not on GamStop. |
| Hold & Spinner | 5×3 with hold-and-win | Varies | Replaces the free spins round entirely. The furthest departure in the family. |
| Halloween, Christmas Bash, Floats My Boat, Keeping It Reel | 5×3 variants | Varies | Look like reskins, are separately certified games with their own feature rules. |
The practical rule across all of them is the one that applies to every family on this site: the figures on any page describe exactly one build of exactly one title. Two games with almost the same name, in the same lobby, from the same studio, are not interchangeable.
“Varies” means we have not confirmed it. Every title in these tables is separately certified, and studios ship most of them in more than one return configuration. We publish a figure only where this site can stand behind it, and the game's own information screen is the only place the loaded build appears — how to read the paytable.
What The Reduced Build Of Big Bass Splash Costs You
Big Bass Splash is advertised at 96.71%. If the operator has loaded a lower configuration instead, this is the difference in pounds over a realistic run of play — change the inputs to match yours.
Configuration bands shown here are reported by operators and game databases; we have not yet read them off a studio document, so treat them as orientation rather than fact.
Worked example. Big Bass Splash at £2 a spin, 600 spins an hour for 10 hours is 6,000 spins and £12,000 staked.
| Configuration | Expected loss |
|---|---|
| 96.71% | −£395 |
| 96.50% | −£420 |
The lower build costs £25 more over the same play.

What A Session On Big Bass Splash Actually Looks Like
Splash pushes more of its return into the feature than Bonanza does, so expect a quieter base game and a wider spread of session outcomes.
RTP describes the long run; it says nothing about an evening, which is what you are actually buying. Ten thousand sessions are simulated below at the advertised 96.71% — the spread is the answer, not the average.
Worked example. £200 played at £2 a spin for 1,000 spins is £2,000 of turnover — more than the bankroll, because winnings are staked again.
| Starting bankroll | £200 |
| Turnover if the money lasts | £2,000 |
| Expected cost of that turnover | −£66 |
