Pick this slot if you want a fishing theme on a 5x4 grid with a line-based mechanic. Wins run along 12 fixed paylines, from the leftmost reel to the right across adjacent reels. Two matching symbols are enough to pay, so smaller wins can happen. Fishing boats, rods, lures and tackle boxes sit alongside the cards A, K, Q, J and 10.
Choose it over other titles for bonus rounds built on collecting. Three, four or five Scatter symbols start Free Spins with 10, 15 or 20 spins. In free spins, the fisherman Wild substitutes for all but Scatter and collects the cash values of Money symbols on screen when it lands. Every fourth collected Wild retriggers 10 spins with x2, x3 or x10 Money multiplier.
Five steps in order
Walk through one round with us, from bet to payout, and see what each step asks of you.
You choose a bet from A$0.12 up to A$240 before the reels turn. The 12 fixed paylines stay the same at every stake.
You watch each payline from the leftmost reel, and a win can start with just two matching symbols on adjacent reels. Symbols pay the amounts shown in the paytable.
You keep an eye on money fish, which carry cash values, and on the Scatter, which opens the Free Spins. The Wild only appears in the Free Spins.
You land three, four or five Scatters, and the Free Spins begin with 10, 15 or 20 spins.
You set a limit before the first spin and stop there, since no one can know in advance how long a session will last.
Pick a bet and think in A$100: the return to player is the share of each A$100 staked that comes back as wins over time. The version running here is shown in the game rules.

Practise before staking
Here you settle whether to start with the demo or move straight to the real game.
Pick the demo to see the reels, since it needs no money and pays nothing. Real play needs an account and the legal age of 18+.
Start playingChoosing to start a session means accepting that the bonus round may or may not appear. How often it comes is not known in advance, and nobody can tell from earlier spins when it will land. The result of one session is random, whatever the RTP shown on this page.
Deciding how much weight to give the RTP starts with one question: which version does Highroller Casino run? That version is shown only in the game rules, so read them before your first spin, and treat the figures on this page as context rather than a promise.
Chasing the biggest prize starts with knowing the ceiling. The maximum win is 4,000 times the bet, and that ceiling is reached very rarely. A round win stops at that cap, however large the stake. Nobody can say in advance whether a given session gets close.
You must be 18+ to play. For support in Australia, call the National Gambling Helpline on 1800 858 858 or register with BetStop, the national self-exclusion register.
Decide your budget before you spin, and treat it as the most you can lose. Stop when the budget is gone, not when a win tempts you.
Pick your stopping point before the first spin, and keep it after a big win too. A win is not a reason to keep playing.
Set deposit and loss limits in your account before you play. They protect your balance when a session runs longer than planned.
Take a break or self-exclude as soon as the game stops being fun for you. BetStop is the national self-exclusion register.

Quick help
Most worries come down to what a spin costs and what it can pay out.
Choose this slot only if long stretches without a big win do not bother you. Its volatility is high, so wins come less often but can be larger than on lower-volatility games. Nobody can know in advance when the bonus will land, so set your budget first.
Compare the RTP before you choose a bet, because it shows the average return over a long run. Bigger Bass Bonanza has an RTP of 96.71 percent, so about A$96.71 comes back for every A$100 staked on average. A single session can end far above or below that average.
Set your bet first, because the top prize scales with it. The maximum win is 4,000 times the bet, which is A$20,000 at a A$5 bet and A$960,000 at the highest bet of A$240. Round wins stop at that cap however the features line up.
Start at the minimum bet of A$0.12 to learn the rules with the least money at risk. The example bets of A$2 and A$5 show how the payouts scale as the stake rises. Check the paytable at A$0.40 before you raise your bet.
Aim for three, four or five Scatter symbols for 10, 15 or 20 free spins. In the free spins, the Wild collects every Money symbol's cash value on screen when it lands. Every fourth collected Wild adds 10 spins with x2, x3 or x10 multipliers, up to three times.
Weigh versions by RTP and top prize before you pick one. This version has 96.71 percent and a 4,000x maximum win. Big Bass Splash 1000 pays 96.52 percent with up to 25,000x, while the other four versions sit at 96.50 to 96.51 percent with up to 5,000x.
