Pragmatic Play's fishing game with money-collecting wilds in free spins, 96.50% RTP, high volatility, and a maximum win of A$1,500,000.

Grid and money symbols. Bigger Bass Splash runs on a 5-reel, 4-row grid with 12 fixed paylines reading left to right. The ocean theme centres on fish symbols that carry random money values each spin. You can toggle Ante Bet to increase scatter frequency, or buy Free Spins and Super Free Spins directly. Released in February 2025, this high volatility slot means wins arrive less often but can be significantly larger.
Who should play this. This slot suits players with a bankroll to absorb long dry spells and appetite for risk. Minimum bet starts at A$0.10, though example bets run A$2 to A$10, giving you control over session size. If you prefer frequent small wins or shorter rounds, the high volatility and paid bonus buys here work better for players chasing bigger payouts over extended sessions.
Bigger Bass Splash and the wild collector. The Free Spins round is where volatility peaks. You trigger it with 3 or more scatters: 3 awards 10 spins, 4 awards 15, and 5 awards 20. During free spins, each wild (the fisherman) collects all money values visible on screen and multiplies them by your current level (1x, 2x, 3x, or 10x). Every fourth wild collected adds 10 spins and advances the multiplier, turning a bonus into a potential cascade.

How free spins start. Land 3, 4 or 5 scatters to trigger 10, 15 or 20 free spins. During the round, each wild symbol collects all visible money values from fish symbols. Every 4 wildcards collected retriggered an extra 10 spins and advances your multiplier from 1x through 2x and 3x to 10x. Five random modifiers can activate before the round starts.
Standard free spins versus the super version. Buy this premium variant for 350 times your stake. All five pre-round modifiers active immediately: more fish, more fisherman, more hooks and dynamite, starting multiplier at level 2, and two bonus spins added to your count. Your round starts with 12 spins; retriggered spins also add 12 each. The wild collect mechanic works the same way.
Spinning between bonuses. During each base game spin, 5 reels and 4 rows hold 12 fixed paylines reading left to right. Fish symbols carry random money values on each spin. Toggle the Ante Bet on to increase scatter frequency; this costs 1.5 times your stake. You can also buy free spins or the super variant directly from the left panel.
Money values accumulate through multiplier levels. Every wild that lands during free spins collects all money symbol values currently visible on screen. The collected amounts stack across your entire bonus round and are multiplied by your current multiplier level—1x, 2x, 3x or 10x. Random dynamite, hook and wipeout events trigger to ensure fish and fisherman land together.
Scatter triggers remain random. The scatter that triggers free spins lands unpredictably. You might reach 100 spins without seeing three scatters, or land them twice in a row. No streak or pattern can tell you when the bonus round starts.
RTP measures the long run, not today. The RTP of 96.50% is an average across thousands of spins. Your single session could return far more, nothing at all, or anywhere between. One player's result tells you nothing about the next.
Maximum win remains an extreme outlier. Bigger Bass Splash can pay up to A$1,500,000 at maximum bet, but that ceiling is reached so rarely that planning around it is not reasonable. Wins much closer to average are far more likely.
The series ranges from 96.50% to 96.52% RTP and from x5,000 to x25,000 maximum win across eight titles released in 2025 and 2026.
Land three or more scatters to trigger free spins, or skip the wait and buy them outright. At a A$10 stake, this costs A$1 000 and grants you 10, 15 or 20 spins depending on scatter count.
All five pre-round modifiers start active in this enhanced version: more fish symbols, more wild fishermen, more random events, a level 2 multiplier head start, and two extra spins. At a A$10 stake, this premium package costs A$3 500 and begins with 12 spins.
Boost your scatter frequency and stay in the base game longer without buying the bonus. The ante bet multiplies your stake by 1.5—at A$10 it becomes A$15—and increases the chance scatters land on the reels naturally.

Luckygem Casino answers what matters most to players starting this fishing slot.
Stake what you can lose. Set a budget before you start playing and only use money you can afford to lose. Once that amount is spent, your session ends.
Win or lose: know when to go. Decide in advance when you will stop playing, even after a big win. Walking away at a set time keeps wins from becoming losses.
Set account limits now. Use deposit limits and loss limits on your account to enforce boundaries automatically. Reality checks and session reminders also help you stay aware.
