Bigger Bass Splash - high volatility fishing game at Spincastle Casino
Pragmatic Play's fishing slot uses Free Spins and Money Collect to build wins across 12 paylines, with 96.50% RTP and wins that come less often and can be much bigger.
How does Bigger Bass Splash work?
The grid and the money symbols. Bigger Bass Splash is a fishing-themed slot with 5 reels, 4 rows and 12 fixed paylines reading left to right. Released in February 2025, it combines a high volatility setup where wins arrive less often but can be much bigger. The grid stays constant across every spin. Fish symbols carry random money values that change each round, adding unpredictability to the base game. Multiple features—wilds, scatters, multipliers and respin mechanics—create the structure of a round.
Who this slot is and isn't for. Bigger Bass Splash suits players who can afford longer dry runs between wins and who want the chance of a larger return. Stakes run from £0.10 to £5 per spin. At the top bet of £0.50, a winning round can pay up to £2,500; push to the maximum £5 stake and the ceiling reaches £25,000. High volatility means this game is less suited to players chasing frequent small wins or those with tight session budgets. The fishing theme and money-collection mechanic appeal to players who enjoy narrative-driven bonus rounds.
Wild symbols collect and multiply. Free Spins define how a round plays out. Land 3 or more scatter symbols to trigger the bonus: 3 scatters give 10 spins, 4 give 15, and 5 give 20. During free spins, every wild that lands collects all the money values showing on screen. Each collection moves you towards a multiplier boost—every 4th wild collected bumps the multiplier (1x to 2x to 3x to 10x) and retriggers 10 more spins. The accumulated money total gets multiplied by your current level before being added to your round total.

From bet to payout: the complete round
Walk through each stage of a spin, from setting your stake to triggering the bonus.
From scatters to collected cash: the bonus at work
Three scatters unlock the spins. Land 3 or more scatters to start: 3 gives 10 spins, 4 gives 15 spins, 5 gives 20 spins. Each time a wild lands during free spins, it collects all money values visible on screen. Every 4th wild collected retrigggers 10 extra spins and pushes your multiplier up (1x to 2x to 3x to 10x).
Money values in every spin. The base game runs across 5 reels and 4 rows using 12 fixed paylines, paying left to right. Fish symbols carry random money values each spin, creating different rewards even when the same symbols land. Three matching fish on a payline form a win.
How the wild builds your total. When the wild (fisherman) lands during free spins, it instantly collects every money value showing on screen at that moment. All collected amounts add together through the entire bonus round and then multiply by your current level (1x, 2x, 3x or 10x) to determine your final payout.

From basic to extreme: how the Big Bass series scales

Unpredictable outcomes and rare ceilings
Scatters decide the bonus timing. Bonus rounds arrive by chance on each spin. The 96.50% RTP covers all spins over millions of rounds, but yours may not trigger Free Spins at all.
One session tells you nothing. Your next session is random regardless of RTP. One player may see £2,500 in a day; another may stake £500 and get nothing back. RTP is the long average only.
When you see that top figure, know it's rare. The maximum win of £25,000 is a ceiling, not a target. At your top bet of £0.50, you'd need perfect conditions across multiple bonus retriggerings to reach it.

Bigger Bass Splash works on chance alone
Bigger Bass Splash starts with a budget. Choose a stake you can afford to lose completely in one session. Your budget is the most important decision you make before spinning.
Control when the session ends. Decide before you play when you will stop, whether you win or lose. A win is a signal to walk away, not a signal to keep playing.
Deposit and loss limits: before and after. Use your account's deposit limits and loss limits to cap what you spend. These tools work in the background to keep you in control.
Step away when you need to. Take a break or use self-exclusion if the game stops being fun or you cannot stick to your limits. GamCare, BeGambleAware and GAMSTOP are there to help.
