Pragmatic Play's 5x4 fishing slot where wild fishermen collect money from fish symbols across free spins with multipliers up to 10x, paying 96.50% RTP on high volatility.

Five reels, money-carrying fish. Bigger Bass Splash takes you fishing across five reels and four rows, with twelve paylines running left to right. Fish symbols on each spin carry random money values that build your potential win. The game launched in February 2025 with high volatility, meaning wins arrive less often but can be much bigger. You'll find features including respins, multipliers, and the Wild fisherman symbol that collects money values from the screen.
Bankroll and bet range fit. This slot suits you if you're comfortable with longer dry spells between wins and have a bankroll to ride them out. The high volatility and maximum win of 5,000 times your bet attract players chasing substantial payouts. You can bet from NZ$0.10 to NZ$300, so both cautious and aggressive bettors find their level. If you prefer frequent small wins or limited session budgets, a lower-volatility game matches you better.
From scatter to multiplier climb. Free spins form the core of what shapes a round. You trigger them with three or more scatter symbols, earning 10 to 20 spins depending on how many land. During free spins, each Wild that lands collects all the money values visible on screen and multiplies them by the current level, which climbs from 1x to 2x to 3x and up to 10x as you collect more Wilds. This mechanic can turn a modest collection into a large win.

You'll know what to expect from the moment you place your first bet through bonus triggers and session limits.
How Free Spins start and grow. Land three or more Scatters to trigger Free Spins: three gives 10 spins, four gives 15, five gives 20. Each Wild that lands collects all visible Money symbol values. Every fourth Wild collected adds 10 spins and increases the multiplier from 1x to 2x to 3x to 10x.
What does the premium free spins option give you? Buy Super Free Spins for 350x your bet and start with all five pre-round modifiers active: more fish, more fisherman, more hooks, wipeouts and dynamites, plus a level 2 multiplier and two bonus spins. You begin with 12 spins; retriggered spins add 12 more. The Wild collect mechanic works the same way.
How do you set up a base game round? Spin five reels across four rows with 12 fixed paylines that run left to right. Fish symbols carry random Money values each spin. Toggle Ante Bet to increase how often Scatters land. Buy Free Spins and Buy Super Free Spins options sit in the left panel during every round.
How the Wild multiplier system builds wins. Bigger Bass Splash uses the Wild fisherman to collect Money values during Free Spins. All visible Money symbol payouts on screen are gathered when the Wild lands, then multiplied by your current level (1x, 2x, 3x, or 10x). Random Dynamite, Hook and Wipeout events ensure fish and fisherman appear together.
Start 10 to 20 Free Spins instantly without waiting for scatters. During the bonus round, a fisherman wild collects all money values from fish symbols on screen, with multipliers climbing as you land more wilds. Costs NZ$50 at a NZ$0.50 bet.
Begin with 12 Free Spins and all five pre-round modifiers active, giving you more fish, more fisherman, and random events that keep them paired on screen. The same wild collect and multiplier mechanic runs throughout. Costs NZ$175 at a NZ$0.50 bet.
Increase your stake by 50 percent to raise the frequency of scatters landing on the reels, making Free Spins trigger more often. At a NZ$0.50 bet, Ante Bet costs NZ$0.75 per spin.

Bonus arrival is unpredictable. When the Free Spins round arrives depends on the reels, not on timing or bet size. You might trigger it on your tenth spin or your hundredth. No pattern predicts when it comes.
Bigger Bass Splash and your next session. Bigger Bass Splash plays at 96.50% RTP over thousands of spins across many players. Your single session could be a win, a loss or breakeven. The RTP does not apply to your game today.
Bigger Bass Splash maximum wins are rare. The maximum win of NZ$1,500,000 is a ceiling that forms once in millions of spins. You will not reach it. Wins on most spins stay far below that figure.
RTP is the average return over thousands of spins. Each RTP figure applies only to the condition shown next to it: the standard game, when Ante Bet is active, or when you buy Free Spins. Your actual results in any session will differ.
