Symbols land on a 5x4 grid of reels, and wins form along 12 fixed paylines read left to right on adjacent reels from the leftmost reel. A line pays from as few as two matching symbols. The theme is fishing: a boat, a rod and reel, a lure, a tackle box and the cards A, K, Q, J and 10 fill the grid. Fish and regular symbols with money values pay per the paytable.
Three to five Scatter symbols on the reels start the Free Spins round. In that round the fisherman Wild appears, substitutes for every symbol except Scatter, and runs Money Collect when it lands, taking the cash values of all money symbols on screen. Each fourth collected Wild retriggers with ten more spins and a Multiplier on the money collected, three retriggers at most.

Many players want to see the free spins screen before committing any money.
Bigger Bass Bonanza guide
The first worry is what a bet costs and when free spins start.
Each spin on the reels uses the bet you pick, from A$0.12 up to A$240. The paytable is set for A$0.50, and A$2 and A$5 are used as examples here.
Wins form when matching symbols land left to right on adjacent reels, across 12 fixed paylines. Fish and regular symbols pay what the paytable shows for their line.
On the reels, money symbols carry cash values, and the Scatter starts the bonus round. Each fourth collected Wild adds 10 spins with an x2, x3 or x10 money collection multiplier.
Three, four or five Scatter symbols on the reels start the free spins, giving 10, 15 or 20 spins. The Wild fisherman appears only during those spins.
A spin on the reels takes the chosen bet from your balance. Set your stop point before the first spin, and keep it.
Bonus rules
Spinbet Casino sets out the bonus rules in full, so you know each step before the first spin.
Three, four or five Scatters start 10, 15 or 20 free spins. The Wild appears only in this mode, replacing all symbols except Scatter. It collects the cash values of all Money symbols on screen. Every fourth collected Wild retriggers 10 spins with a x2, x3 or x10 multiplier.
Base Game spinsCollected cash
Every spin starts on the leftmost reel of the 5x4 grid. Wins are read left to right across adjacent reels on 12 fixed paylines. Fish and regular symbols with a Money value pay as the paytable shows.
Choosing a betWins in money
Every spin returns part of the stake, and return to player counts that part per A$100 staked over a very long run. The version Spinbet Casino runs is shown in the game rules.

Trial Version
After reading this, you will know whether to start in the demo or open a real account.
Reels spin in the demo without any money and pay nothing, while real play needs an account at Spinbet Casino and the legal age of 18+.
Start playingThree to five Scatter symbols landing on the reels start the free spins, and how often that happens is not known in advance. The result of one session is random, whatever the RTP. The RTP describes the average over a very large number of rounds, not the outcome of the next spin or the next hour of play.
Each spin on the reels follows the RTP of one version of the game. Which version runs here is shown only in the game rules, so read them before the first spin if the version matters to your choice.
A top combination on the reels can reach the cap of x4,000 the bet, which is the most a round can pay. That ceiling is reached very rarely, and no one can plan a session around it.
Players must be 18+. For support, call the National Gambling Helpline on 1800 858 858, or use BetStop, the national self-exclusion register.
Set a session budget before the first spin, and treat that amount as the most you will lose. Do not add money to chase a loss.
Decide when you will stop before the session starts, and keep to it after a win. A win does not change your planned budget.
Use the deposit and loss limits in your account to cap spending. Set them before you open the game, not during a losing run.
Step away when the game stops being fun. A longer break or self-exclusion is open to you if short pauses do not help.
Before you pick
Spinbet Casino sets each game's rules out in the same plain format, so comparing titles stays simple.
Know what to expect
Spinbet Casino sets out each slot's figures in plain terms before you play.
Bigger Bass Bonanza is a high volatility slot, so results can swing widely between small and large amounts. How often a large win comes cannot be known in advance by any player.
The lowest bet on Bigger Bass Bonanza is A$0.12 and the highest is A$240. The bets A$0.50, A$2 and A$5 used on this page are examples only, and they are not the limits of the game.
Bigger Bass Bonanza has a higher RTP than each other version of the series, 96.71% against 96.50% to 96.52%. Its maximum win is x4,000 of the bet, below the x5,000 of four series versions and the x25,000 of Big Bass Splash 1000.
The game's RTP is 96.71%, which is the share of all stakes returned to players over a very long run. It says nothing about the outcome of one session, which can end well above or below the stake.
Three, four or five SCATTER symbols start the free spins, giving 10, 15 or 20 spins. The fisherman WILD appears only during the free spins, and every fourth collected WILD adds 10 more spins with a multiplier of x2, x3 or x10, for up to three retriggers.
