Big Bass Splash is a fishing-themed slot from Pragmatic Play, developed in partnership with Reel Kingdom. Released in June 2022, it sits in the Big Bass series alongside Big Bass Bonanza, and takes the core fishing mechanic underwater to an ocean setting. It runs on a 5x3 grid with 10 fixed paylines, an RTP of 96.71%, and high volatility.
Big Bass Splash RTP, Volatility and Max Win
The RTP on Big Bass Splash is 96.71% at the default setting, which is above the industry average. Pragmatic Play does offer lower RTP variants to some casino operators - typically 95.50% or 94.50% - so it is worth checking the paytable on the casino you are using. The volatility is high, meaning wins arrive in clusters rather than steadily. The maximum win is 5,000x your stake.
The bet range runs from £0.10 to £250 per spin. Given the high volatility and a hit rate of around 1 in 7 spins, bankroll management matters. Many players find the game is best approached with smaller stakes to give the free spins feature room to do its work.
Symbols and Base Game
The reel set sits in an underwater reef scene. The high-value symbols are fish of different species, each carrying a cash value on the face of the symbol. These money fish are the key to the game's main mechanic - their values are collected by the fisherman wild during free spins rather than paid out through standard line wins.
The fisherman is the wild symbol. In the base game he substitutes for all other symbols except the scatter. The scatter is a fishing float. Landing three or more scatters anywhere on the reels triggers the free spins round.
The base game also includes three random modifier features that can activate before a spin. The dynamite blast lands on random positions and converts symbols to higher-value fish. The hook pulls in a missing scatter or wild to complete a bonus trigger. The boat drops extra money fish onto the grid. These modifiers fire rarely but can set up free spins triggers from otherwise thin-looking boards.
Free Spins Feature
Landing three scatters awards 10 free spins. Four scatters gives 15, and five gives 20. This is where the game's main payout potential lives.
During free spins, every time the fisherman wild lands he collects the cash values shown on all money fish visible on the reels at that moment. The collected total is paid out at the end of that spin. The more money fish on the reels when a fisherman lands, the larger the payout.
The multiplier system increases each time you collect a fisherman. The first fisherman collected applies no multiplier. The second activates a 2x multiplier on all future collections. The third moves it to 3x, and collecting a fourth fisherman during the same free spins round locks in a 10x multiplier for the remainder of the feature. Getting to that 10x level with a board full of high-value money fish is where the larger wins come from.
Free spins can also be retriggered. Landing three more scatters during the bonus adds 10 extra spins. Crucially, the multiplier level you have reached carries over into the retriggered spins - you do not reset to zero.
How Big Bass Splash Compares to Big Bass Bonanza
Big Bass Bonanza uses the same fisherman collection mechanic in a pond-side setting. Big Bass Splash moves the action underwater and adds the base game modifiers, which Big Bass Bonanza does not have. The multiplier cap and free spins trigger work the same way in both games. Big Bass Splash is generally considered the more feature-rich of the two, though both carry the same 5,000x max win and high volatility profile.
The series has expanded significantly. Big Bass Splash 1000, released in December 2025, carries 1,000x money symbols and a 25,000x max win potential. Big Bass Trophy Catch followed in April 2026 with its own set of modifiers. The original Big Bass Splash remains one of the most played games in the series across European markets.
Mobile Play
Big Bass Splash runs in HTML5 and loads directly in a mobile browser without an app download. The interface scales cleanly across screen sizes. The free spins feature is equally playable on mobile, and the modifier animations translate well to smaller screens. Compatible with iOS and Android devices.
Is Big Bass Splash Worth Playing?
The 96.71% RTP is solid for a high volatility slot. The fisherman collection mechanic gives the free spins feature a clear escalation structure - you can track your multiplier progress through the feature rather than waiting on random outcomes. That transparency makes the bonus more engaging than a simple free spins respin.
The downside is that the base game is dry between bonus triggers. With a hit rate of roughly one winning spin in seven, and most base game wins being small line pays, the game can feel slow unless the modifiers fire. Players looking for more frequent base game action may prefer something with a lower volatility profile. For those happy to ride out drought periods for the free spins feature, Big Bass Splash delivers when the bonus hits.

Collecting multiple fishermen increases a multiplier: the second fisherman activates 2x, the third activates 3x, and the fourth locks in 10x for the rest of the feature.
