Pick a bet and spin a 5x4 grid on the water, with fishing and ocean symbols on every reel. The game has 12 fixed paylines that read left to right, so a win needs three matching symbols in a line starting from the first reel. Fish symbols carry a random money value on each spin, and those values feed the bonus round.
Chase the free spins with three or more Scatter symbols, which award 10, 15 or 20 spins. The Money Collect mechanic sets this slot apart: during those spins, each landing fisherman WILD collects every money value visible on screen. Each fourth WILD adds 10 spins and lifts the Multiplier from 1x to 2x, 3x and 10x. Random pre-round modifiers and Respin add more variety.
When the bonus lands
Extreme Casino lists each mode with its exact figures before you play.
Chase 3+ Scatters: 3 give 10 spins, 4 give 15, 5 give 20. A Wild, the fisherman, collects the Money values of fish on screen. Every fourth Wild adds 10 spins and lifts the multiplier 1x, 2x, 3x, 10x. Modifiers, 0 to 5, are picked at random first.
Base game reelsSpins and multipliers
Buy Super Free Spins at 350x the bet. All 5 pre-round modifiers are active from the start: more fish, more fisherman, more hooks, dynamites and wipeouts, start from level 2, +2 spins. It starts with 12 spins, and each retrigger adds 12. Wild and multiplier rules match Free Spins.
Base gamePremium free spins
Pick a bet from A$0.10 to A$300 and spin the 5x4 grid. The 12 fixed paylines run left to right. Fish symbols carry random Money values on every spin. Hit three or more Scatters to trigger Free Spins.
Game lobbyMoney on fish
Land Wilds during Free Spins and each one collects all Money symbol values on screen. Collected values build across the round and are multiplied by the current level: 1x, 2x, 3x or 10x. Random Dynamite, hook and wipeout events make fish and fisherman appear together.

Know every step
You will know how each round runs, from setting your bet to stopping your session.
Choose your bet from A$0.10 up to A$300 before the first spin. Each spin is paid on that stake, so an A$5 bet and an A$10 bet pay different amounts.
Line up three or more matching symbols on the 5x4 grid, read left to right across 12 fixed paylines. Fish symbols carry random money values each spin.
Look for Scatter symbols, since three or more start the free spins. The Wild fisherman then collects fish money, and the multiplier rises from 1x to 2x, 3x and 10x.
Land three, four or five Scatter symbols to start 10, 15 or 20 free spins. Every fourth Wild collected adds 10 more spins and moves the multiplier up a level.
Set your limit before the first spin, then stop when you reach it. Results are random, so nobody can know in advance how a session will end.
During the bonus
Most players worry about missing what a win or bonus looks like on screen.
Pick a bonus buy and pay a multiple of the bet; at a A$10 bet, Free Spins cost A$1,000 and Super Free Spins A$3,500.
| Ante bet | Cost A$ | RTP |
|---|---|---|
| Buy Free Spins at 100x | x100 · A$1,000 | – |
| Super Free Spins at 350x | x350 · A$3,500 | – |
Stake A$100 and the return to player of 96.50% means A$96.50 returns to players on average over a very long run. The version running here is listed in the game rules.

Learn Before Betting
The usual worry is losing cash before you understand the reels, and the demo removes it.
Play the demo first, since it needs no money and pays nothing. The real game needs an account at Extreme Casino and a player aged 18 or older.
Play for realYou decide to play Bigger Bass Splash for the bonus round, but nobody can say when it will land. How often the free spins trigger is not known in advance. Each spin is random, so one session can finish far above or below its starting balance, whatever the RTP shows.
You want to know which RTP version Extreme Casino runs before you stake. That answer appears only in the game rules, so open them before the first spin and check the version listed there. Each version carries its own figures, so read the listed RTP next to the money tables.
You look for the biggest possible payout before you bet. The maximum win of Bigger Bass Splash is a ceiling reached very rarely, set at x5,000 of the bet. Treat it as the upper limit of the payout, not as a target for any single session.

Plain facts
After this, you can judge the buy costs, versions and maximum win before you wager.
Yes. The Free Spins buy costs A$1,000 at a A$10 bet, and Super Free Spins costs A$3,500 at the same bet. The Ante Bet toggle raises the stake to A$15 at A$10.
Bigger Bass Splash carries an RTP of 96.50 and a maximum win of x5,000. Big Bass Splash 1000 pays back 96.52 and reaches x25,000, so the two differ on both figures.
The highest prize is x5,000 times the bet, which is A$50,000 at the A$10 top bet and A$1,500,000 at the A$300 maximum bet. Reaching it depends on luck, and nobody can predict when a round will get there.
Three or more SCATTER symbols start the Free Spins. Three give 10 spins, four give 15 and five give 20. Nothing in advance shows how often this happens.
Volatility is high on this slot. That means results swing widely, so a session can go long without a large win and one round can change the balance sharply. How the swings fall is unknown before you play.
The RTP is 96.50 percent, based on A$100 staked over the long run. Other versions in the series sit between 96.50 and 96.52, so the gap is small and results still vary from session to session.
