A Pragmatic Play slot where fish symbols hold money values that wilds collect during free spins, triggering multipliers up to 10x. High volatility, 96.50% RTP standard.

How do the reels work? Bigger Bass Splash puts you on a 5-reel, 4-row grid where fish symbols carry random money values every spin. The 12 paylines run left to right, and wins form when matching symbols land on a line. Released in early 2025 by Pragmatic Play, the game combines a fishing theme with a money-collect mechanic that triggers during free spins. The high volatility means wins come less often but can be much bigger when they land.
Who should play this slot? This slot suits players who enjoy waiting longer between wins for the chance at larger payouts, and who have a bankroll to support a high-volatility game. The flexible bet range from A$0.10 to A$300 works for most players, though the ante bet option (which costs 1.5 times your stake) is designed for those chasing bonus features faster. It is not ideal if you prefer frequent small wins or want to play on a very tight budget.
Bigger Bass Splash free spins explained. Free spins are the core of a session here. When 3 or more scatters land, you unlock 10, 15 or 20 spins depending on the scatter count. During free spins, the fisherman (wild symbol) collects all the money values visible on screen each time it lands. Every fourth wild collected boosts your multiplier and adds 10 more spins, climbing from 1x through 2x and 3x up to 10x. This collect-and-multiply cycle is what shapes every bonus round.

Scatter triggers, wild collects. Three or more scatters launch 10, 15 or 20 free spins depending on how many you land. The wild fisherman collects all money values visible on screen when it lands. Every fourth wild collected retriggers 10 additional spins and advances the multiplier through levels.
Premium free spins package. This premium variant starts with 12 spins and all five pre-round modifiers active from the beginning, including extra fish, extra fishermen and an immediate level 2 multiplier. Retriggered spins award 12 additional spins using the same collection and multiplier mechanics.
Before free spins arrive. Five reels across four rows hold 12 fixed paylines that pay left to right. Fish symbols carry random money values each spin. Toggle the ante bet to increase scatter frequency, or purchase free spins directly from the left panel before you spin.
Watch your multiplier climb. Each landing wild collects every money symbol value showing on the reels during free spins. Collected amounts accumulate throughout the entire round and multiply by your current level multiplier, which ranges from 1x through to 10x as wilds are collected.
Trigger free spins without waiting for scatters to land. You'll spin 10 to 20 free rounds depending on scatters collected, with wilds collecting money values and advancing your multiplier. Costs A$200 at your example bet.
Start with all five pre-round modifiers active and 12 free spins, giving you better odds of landing fish and fisherman symbols together. Wilds collect money across the entire round, multiplied by your advancing level. Costs A$700 at your example bet.
Multiply your stake by 1.5 and boost how often scatters appear during the base game. Your A$2 bet becomes A$3, but you'll trigger free spins more regularly. This changes your odds without buying the bonus outright.
RTP is the average amount returned over many thousands of spins. The 96.50% figure applies when you play the standard game, when you toggle the Ante Bet, or when you buy Free Spins—each condition uses this same return rate.
When free spins arrive. The free spins round may come early or take many spins to trigger. No amount of play guarantees when or whether scatters will land on your reels.
Session outcomes and probability. Even at 96.50% RTP, the result of your session is governed by chance. You might win significantly or lose your stake regardless of the long-term figure.
Maximum win ceiling. The maximum win of A$1,500,000 sits far above typical play. Reaching it stays exceptionally rare, not a realistic target for any single session.
The Big Bass series ranges from 96.50% to 96.52% RTP, with maximum wins from x5000 to x25000. Each game offers distinct themes and bonus mechanics.

Decide your limit first. Set a maximum amount you can afford to lose before you begin. Stick to it no matter how the session goes, whether you're ahead or behind.
Plan your exit point now. Decide when you'll stop playing before your session starts. Landing a big win doesn't mean you should keep spinning to chase something bigger.
