Pragmatic Play's five-reel boxing slot with free spins, money collection and multipliers. 96.50% RTP. High volatility: wins come less often and can be much bigger.

Fishing and boxing on 10 paylines. Big Bass Boxing Bonus Round is a five-reel, three-row slot built around a fishing and boxing theme. You spin across 10 fixed paylines, and wins form left to right when matching symbols land on a payline. The game launched in June 2025 and carries high volatility, meaning wins come less often but can be much bigger. Its main pull is the Free Spins mode, where coloured Wild boxers appear and collect Money symbol values while multipliers build.
Smaller bets or bigger potential? This slot suits players who can handle stretches without wins and have a bankroll for the swings that high volatility brings. You can stake from £0.10 to £5, so smaller bets keep your session longer if that matters to you. Big Bass Boxing Bonus Round is less suited to players chasing frequent small wins or those who prefer to know bonus rounds will come regularly. The theme and boxer Wilds appeal most to players who enjoy sports-themed games.
Free Spins and the multiplier chase. Free Spins reshape how a round plays. Land 3 to 5 Scatter symbols to trigger 15, 20 or 25 spins. During this mode, Blue and Red Wild boxers appear on every reel and collect the value of Money symbols they land on. Every fourth Wild you collect per colour builds your multiplier from 1x upwards, and hitting four Wilds per colour again retriggers 10 more spins. This chaining can push your multiplier to 10x, giving Free Spins the real power in the game.

Trigger and collect. Three to five scatter symbols trigger 15, 20 or 25 free spins. Blue and Red Wild boxers collect Money symbol values on all reels. Every fourth Wild per colour retriggers 10 more spins and raises the multiplier from 1x to 2x to 3x to 10x. Up to four retrigger levels per meter.
Big Bass Boxing Bonus Round base game layout. The base game runs across five reels and three rows with 10 fixed paylines paying left to right. Standard symbols and scatters land on the grid. Wild symbols do not appear in this mode; they arrive only when free spins start.
RTP is the average return over thousands of spins played across many players and sessions. The 96.50% figure applies only to the standard game at Big Bass Boxing Bonus Round. This is a long-term average; any single session will differ.
The highest stake you can place is £5 per spin, with a maximum win of £25,000 at that bet level on Big Bass Boxing Bonus Round.
Autoplay is not available for this slot in your market, so you control each spin individually throughout your session.

Big Bass Boxing Bonus Round bonus timing. When the three scatters that trigger free spins will land is not guaranteed. A session may end without reaching the bonus round at all, no matter how long you play.
Your session is random despite the RTP. Your next spin's result follows no pattern and cannot be predicted. The 96.50% RTP describes long-term return to staked money across many players, not any one session.
The maximum win is not the typical outcome. The maximum win of £25,000 at your £5 bet is a ceiling reached extremely rarely. Most sessions will deliver results far below this figure.
The Big Bass series ranges from 96.50% to 96.52% RTP, and from £5,000 to £25,000 maximum win. Big Bass Splash 1000 stands alone with a £25,000 ceiling.
