A Pragmatic Play fishing slot where wild symbols collect money values from other symbols during free spins, with an RTP of 96.50% and high volatility.

Bigger Bass Splash and its money mechanic. Bigger Bass Splash is a fishing-themed slot on five reels and four rows, released in February 2025. Fish symbols land with random cash values each spin, and a Wild fisherman character triggers the core mechanic: collecting those money amounts during the bonus round. The game runs 12 paylines, left to right. Its high volatility means wins come less often and can be much bigger. An Ante Bet toggle lifts your bet by 50 per cent to boost scatter frequency.
Know whether this volatility fits you. This slot suits players with a bankroll for longer dry spells and the patience to chase bigger payouts. Its A$0.10 to A$300 bet range lets you scale your stake, and both Free Spins and Super Free Spins can be bought to skip straight to the bonus. If you prefer regular small wins and shorter play sessions, the high volatility and the cost of triggering features through play will work against you.
When Free Spins start, what changes. Free Spins are triggered by three or more scatter symbols and run on the same five-by-four grid. What shapes each spin is the Wild landing: it instantly collects all money values visible on the reels, and those amounts are multiplied by your current level (1x, 2x, 3x or 10x). Every fourth Wild you collect retriggers ten extra spins and bumps your multiplier up. A random modifier before the round starts can shift what lands, stacking the odds in your favour.

From scatters to spinning. Three or more scatters trigger Free Spins: 3 scatters give 10 spins, 4 give 15 spins, 5 give 20 spins. Each wild that lands collects all money symbol values on screen. Every fourth wild collected retriggered 10 extra spins and advances the multiplier from 1x to 2x to 3x to 10x.
Pay to skip straight in. Buy Super Free Spins for 350 times your bet to start with all five modifiers active: more fish, more fisherman, more hooks and dynamite, level 2 multiplier from the start, and 2 bonus spins. You get 12 spins; retriggered spins add 12 more. The wild collect mechanic and multiplier progression work the same way.
Bigger Bass Splash between free spins. Five reels by four rows with 12 fixed paylines running left to right. Fish symbols carry random money values each spin. Toggle Ante Bet to multiply your stake by 1.5 and increase how often scatters land. Buy Free Spins and Buy Super Free Spins from the left panel whenever you want.
Bigger Bass Splash wild mechanic. During Free Spins, every wild landing collects all visible money symbol values at once. Those values build up throughout the entire bonus round and multiply by your current level (1x, 2x, 3x or 10x). Random dynamite, hook and wipeout events make sure fish and fisherman appear together on screen.
Read moreRTP is a long-run average calculated over a very large number of spins. The 96.50% figure applies to the standard game, the Ante Bet mode, and when you buy Free Spins; each condition uses the same RTP.
Don't count on the bonus. Free Spins trigger when three or more Scatter symbols land, but how often this happens varies with every spin. No player can forecast when the bonus round will arrive or guarantee it will come within any timeframe.
RTP is the long game. The RTP of 96.50 percent describes long-term results across many spins. Any single session can deliver far less, far more, or nothing at all. Short-term outcomes are random and independent of the average figure.
What is the real chance of hitting max win? The maximum win of A$1,500,000 is a theoretical ceiling reached extraordinarily rarely. Most sessions will settle well below this figure. Maximum wins are not typical results but mathematical extremes.
