Learn how Bigger Bass Splash plays

Choose a stake, then spin a 5x4 reel grid themed around fishing and the ocean. Bigger Bass Splash pays on 12 fixed paylines read from left to right, and three matching symbols are enough for a win. Money Fish symbols carry random money values that change on every spin, so the same fish can show a different amount from one spin to the next.

Chase three or more Scatter symbols to enter Free Spins, where a Wild fisherman collects the money of fish on screen. Each fourth Wild collected adds ten spins and lifts the multiplier from 1x to 2x, 3x and then 10x. Collected money adds up and is multiplied by the current level. Between zero and five random modifiers apply before each round.

Buy the bonus and skip the wait

Players who want the bonus now can buy it for 100 times the bet, which is A$500 at a bet of A$5.

Bigger rounds, clear rules

How do the free spins begin?

This block settles how each mode starts, what it adds, and where the money comes from.

Land three scatters to start

Three or more scatters start the round: 10 spins for three, 15 for four, 20 for five. Each landing WILD collects fish money on screen. Every 4th WILD collected adds 10 spins and steps the multiplier through 1x, 2x, 3x and 10x. 0–5 pre-round modifiers are picked at random.

Base gameFree spins round

Bigger Bass Splash premium spins

Starts with 12 spins, and retriggers award +12. All 5 pre-round modifiers are active from the start: more fish, more fisherman, more hooks, dynamites and wipeouts, start from level 2 and +2 spins. The same WILD collect mechanic and multiplier progression apply.

Base gamePremium free spins

Where do the 12 paylines run?

Each spin lands on a 5x4 grid with 12 fixed paylines, read left to right. Three matching symbols is the fewest that pay. Fish symbols carry random money values on every spin, so the same fish can pay differently from one spin to the next.

Game lobbyFish money values

Fish money stacked by the multiplier

A WILD landing in free spins collects every money symbol value visible on screen. Collected values build across the whole round and are multiplied by the current multiplier: 1x, 2x, 3x or 10x. Random dynamite, hook and wipeout events make fish and fisherman appear on screen together.

Know your payouts

How does a round of Bigger Bass Splash run?

Useful before your first spin, or when you want to follow one round from bet to payout.

  1. Bigger Bass Splash bet range

    Choose a bet between A$0.10 and A$300 before the first spin. Every win is a multiple of the stake, so a higher bet raises each payout.

  2. Bigger Bass Splash: fixed paylines

    Three or more matching symbols on a fixed payline, read left to right, make a win. Fish carry random MONEY values each spin, so the same fish pays different amounts.

  3. Know what starts Free Spins

    In the base game, fish carry MONEY values and three or more SCATTER symbols start the Free Spins. The WILD fisherman and multiplier belong to the Free Spins.

  4. Scatter count and spin total

    Three SCATTER symbols give 10 spins, four give 15 and five give 20. Between zero and five pre-round modifiers are picked at random before the first free spin.

  5. Keep the total spend in check

    Set the total you will spend before the first spin. Each round is random, so no session result can be known in advance.

What RTP does not predict in one run

Decide how much to stake knowing that the bonus round cannot be timed. How often it comes is not known in advance, and no count of spins predicts it. The result of one session is random, whatever the RTP. A short run can end in a large win or a loss, and the figures on this page do not change that.

Check the game rules before you stake, because only they show which RTP version Gwin77 Casino runs. A tile name or a series title does not tell you the version. Compare the rules of each version you see before you play.

Read the maximum win as a ceiling, not a goal you can plan around. It is reached very rarely, and no player can aim for it on a given spin. Judge the game by how each round plays and what the paytable pays.

After reading, you will have checked the RTP, volatility and top prize before your first bet.

How is Bigger Bass Splash different from Big Bass Splash 1000?

Bigger Bass Splash has a maximum win of x5,000 and an RTP of 96.50%. Big Bass Splash 1000 has an RTP of 96.52% and a maximum win of x25,000. Big Bass Blast, Big Bass Football Bonanza and Big Bass Trophy Catch match this RTP and maximum win.

What is the RTP of Bigger Bass Splash and its versions?

The slot has one RTP version, 96.50%. That means the game returns A$96.50 for every A$100 staked over a very large number of spins. No single session follows that average.

Can I try Bigger Bass Splash at the lowest stake first?

Players can start at A$0.10, the lowest bet in the game. A lower stake lets you watch how fish, wilds and free spins run before raising it. At A$0.10 each spin costs a small fraction of the A$5 example bet.

How volatile is Bigger Bass Splash, high or low?

Volatility here is high. Wins arrive less often than in low volatility games, but they can be larger. Long stretches of spins without a win are part of how this game plays.

What is the biggest win Bigger Bass Splash pays in Australian dollars?

The top win is x5,000 times the bet. At the A$5 example bet that comes to A$25,000. The game allows bets up to A$300, where the same multiple reaches A$1,500,000.
