A 5x4 grid with 12 fixed paylines frames Bigger Bass Splash, a Fishing and Ocean video slot. Wins are read from left to right, and a payline pays when at least 3 matching symbols land on it. Fish symbols carry random money values on every spin, so the same layout can pay a small amount or a large one. Four boat and tackle symbols sit alongside the card symbols A to 10.
Three Scatter symbols start 10 free spins, four start 15 and five start 20. During those spins the Wild fisherman collects every money value on screen, and each fourth Wild collected adds 10 spins and moves multiplier up from 1x to 2x, 3x and 10x. The Ante Bet increases Scatter frequency. Super Free Spins start with 12 spins and all five pre-round modifiers active.

Bonus guide
This block settles how many spins you get, how they start, and how the money is collected.
Three or more scatters start free spins: 10, 15 or 20 for three, four or five. Pre-round, 0 to 5 modifiers are picked randomly. Each WILD fisherman collects fish money values on screen. Every 4th WILD collected adds 10 spins, lifts the multiplier from 1x to 2x, 3x, 10x.
Base game spinExtra spins
All five modifiers are active from the start: MORE FISH, MORE FISHERMAN, MORE HOOKS/DYNAMITES/WIPEOUTS, START FROM LEVEL 2 and +2 SPINS. It begins with 12 spins, and each retrigger adds 12. WILD collection and multiplier steps work as in the standard free spins.
Base game betPremium free spins
Five reels by four rows, with 12 fixed paylines read left to right. Fish symbols carry random money values on each spin. Free spins open once you land three or more scatters.
Placing a betFish money values
During free spins, each landing WILD collects all MONEY symbol values visible on screen. Collected values build up through the whole 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 on screen.

A$500 buys Free Spins at the A$5 bet, which is 100 times the bet, and Super Free Spins cost A$1,750, or 350 times the bet.

Play guide
Ozwin Casino lays out each round in order, so you know the rules before your first bet.
A$0.10 is the lowest bet and A$300 the highest, so you pick a stake before each spin. Every stake pays the same 12 fixed paylines across 5 reels and 4 rows.
3 matching symbols pay on any of the 12 fixed paylines, read from left to right. Fish symbols carry a random money value that is set again on every spin.
3 or more Scatter symbols trigger the bonus, and the Wild fisherman collects fish money during the free spins. Multipliers climb from 1x to 2x, 3x and 10x during it.
3 Scatter symbols start 10 free spins, 4 start 15 and 5 start 20. Every 4th Wild collected adds 10 more spins and raises the multiplier one step.
A$300 is the highest bet, so set your limit before the first spin. The National Gambling Helpline is on 1800 858 858 if you want to talk.
3 SCATTER symbols start the Free Spins, but how often that bonus round comes is not known in advance. The result of one session is random even with a 96.50% RTP, because the RTP is a long-run figure over very many rounds, not a promise for a single visit.
96.50% is the RTP of the version described on this page. Which RTP version runs in the game you open is shown only in the game rules, so read them before you bet, and check how the version in play differs from the others.
x5,000 is the maximum win of Bigger Bass Splash, a ceiling that is reached very rarely. No player can count on it, and the figure says nothing about how any single session will end, so plan each bet with that in mind.
You must be 18+ to play. For help, call the National Gambling Helpline on 1800 858 858, or self-exclude through BetStop, the national self-exclusion register.
Decide how much you will spend before you open the game, and stop when that amount is gone.
Set your stopping point before the first spin, and keep it after a win as well as after a loss.
Use the deposit and loss limits in your account before you play, and do not raise them during a session.
If the game stops being fun, take a break or self-exclude through BetStop instead of chasing losses.

Four Short Answers
At Ozwin Casino we put the numbers first, so you know the rules before you spin.
96.50% RTP and a top win of x5,000 set this version apart. Big Bass Splash 1000 returns 96.52% and pays up to x25,000, so its top prize is five times larger.
96.50% RTP comes with high volatility, so wins arrive less often but can be large. Long stretches without a big win are part of how this slot plays.
x5,000 is the top prize as a multiple of the bet: A$25,000 at the A$5 example bet and A$1,500,000 at the A$300 maximum bet. It is a ceiling, not an expected result.
3 Scatter symbols trigger 10 free spins, 4 trigger 15 and 5 trigger 20. During those spins, each Wild collects the fish money on screen, and every 4th Wild retriggers 10 more spins.

I check each payment method and its limits against the cashier, from the A$12 minimum deposit to the A$28,900 withdrawal ceiling, and I work through the identity, address and payment checks myself.
