Big Bass Splash slot

Big Bass Splash: where it fits in the series

Reel Kingdom made its name with Big Bass Bonanza in December 2020, and the studio has since built an entire franchise on the same idea, distributed through Pragmatic Play. Big Bass Splash is one of the main follow-ups. It shares the 5×3 grid, 10 lines and fisherman-collects-fish mechanic, but lifts the published max win from 2,100x on the original to 5,000x.

That higher ceiling is the key to understanding the game. Both games publish the same 96.71% RTP, so the extra top-end potential has to be balanced somewhere, usually in how often meaningful features land. The two are compared in detail in Big Bass Bonanza vs Big Bass Splash.

How the Big Bass Splash slot machine works

The game's random number generator decides the outcome the instant you press spin. The reels, the splash animations and any reeling-in are presentation. A paid spin works like this:

1. Choose the stake; all 10 lines are fixed.
2. Spin. The RNG fixes the symbols on all five reels.
3. Line wins of three or more matching symbols from the leftmost reel are paid; some high symbols pay for two.
4. Fish symbols showing cash values can land; in the base game they pay only when they form a normal line win.
5. Three or more scatters start the free spins.
6. During free spins, any fisherman wild collects the cash values of every fish on screen.

That split between base game and free spins is why fish in the base game can feel frustrating. Without a fisherman to collect them, their cash values are just a preview of what the feature can do.

Fish money symbols and the fisherman wild

Each fish symbol shows a value expressed as a multiple of your stake. The fisherman symbol is a wild that, during free spins, collects the total of every fish visible on the reels. This is a classic cash collect mechanic.

Worked example at 20p a spin: a free spin shows three fish worth £1, £2 and £10 and one fisherman. The fisherman collects £13. If two fishermen land on the same spin, each collects, so the total is £26. Any normal line wins on the spin are paid as well.

Fish values in the game are shown in pounds at your current stake. They are set by the RNG on each spin; there is no way to influence them.

Big Bass Splash free spins and multipliers

Scatters trigger the free spins, with more scatters awarding more spins. Inside the round, a counter tracks every fisherman you collect. Each fourth fisherman retriggers the round with extra spins and raises a multiplier on the fish values the fisherman collects, a form of increasing multiplier in free spins.

Before the round begins, the game can also apply random modifiers that change the reels for that round, such as extra fish or extra fishermen. The exact list, the spins per scatter count and the multiplier at each level are in the help screen; read it before relying on any figure, because the Big Bass games differ in these details.

Big Bass Splash RTP and cost per 100 spins

The published Big Bass Splash RTP is 96.71%, a house edge of 3.29%. Pragmatic Play, which distributes Reel Kingdom's games, can offer lower-RTP versions to casinos, so the figure in the help screen at your casino is the one to trust.

With high volatility, most of the RTP is paid through the free spins. A session of 100 spins that doesn't trigger the feature will usually lose much more than the average shown.

Big Bass Splash max win at UK stake limits

The published Big Bass Splash max win is 5,000 times the stake. In pounds:

Stakes on online slots in Great Britain are limited to £5 a spin for players aged 25 and over and £2 for those aged 18 to 24, under the Gambling Commission's stake limit rules (opens in a new tab). Reaching the cap needs a free spins round that collects many fishermen and high-value fish at the top multiplier; most rounds pay far less.

How UK rules change Big Bass Splash

Versions played outside Britain may show a button to buy the free spins. Games supplied to Great Britain don't offer it, so the only way into the round is through scatters; see bonus buy in the UK.

The Commission's responsible product design standard (opens in a new tab), in force since 31 October 2021, also removes autoplay and turbo spins, sets a 2.5-second minimum per spin, bans slam-stop and stops the game celebrating a return no bigger than your stake. Our autoplay ban and net position rule pages explain what you'll see on screen.

Other Big Bass slots and similar fishing games

The franchise is large and each game has its own figures. Pages we cover include:

• Big Bass Bonanza: the 2020 original.
• Bigger Bass Bonanza: a larger-grid follow-up.
• Big Bass Bonanza Megaways: the formula on Megaways reels.
• Big Bass Hold & Spinner: adds a hold-and-win feature.
• Big Bass Amazon Xtreme: a jungle-river spin-off.

Outside the series, Fishin' Frenzy from Blueprint Gaming uses a similar fisherman-collects idea. Our guide to fishing slot machines explains how the genre developed.

Is Big Bass Splash worth playing?

It suits adults who already like Big Bass Bonanza and want more top-end range, accepting longer quiet spells. If you prefer a gentler game, compare it with our high-RTP slot machines list or browse all slot reviews.

Big Bass Splash myths

• "Lots of fish in the base game means free spins are close." Each spin is independent. Fish values in the base game don't build towards anything.
• "Reaching the third fisherman means the fourth is due." The counter only tracks what has landed; the next spin is still random.
• "Splash pays more than Bonanza because the max win is higher." Both publish the same RTP; the higher ceiling is balanced elsewhere in the maths.

Big Bass Splash demo play

You can usually try a Big Bass Splash demo after age verification, which UK operators have required before free play since May 2019. Under the Commission's play-for-free standard (opens in a new tab), a demo must reflect the real game. Pragmatic Play also lists its portfolio on its studio website (opens in a new tab). A demo shows the collect mechanic clearly, but its results won't predict a real session.

Where to play Big Bass Splash in the UK

The Big Bass games are widely stocked, but check the casino's lobby for Big Bass Splash before signing up, as availability changes. Note the difference between the two games when reading offers: PlayOJO's 80 no-wagering free spins, for new UK customers making a first deposit of £10 or more, are played on Big Bass Bonanza at 10p each, not on Splash; see our Big Bass Bonanza free spins page. Coral gives new players 100 free spins at 10p after depositing and betting £10 on slots, and Ladbrokes gives up to 500 free spins over 10 days after £10 of slot play; both use selected games. 18+, terms apply.
