Pick this game if you want a fishing slot with a horror theme. Big Bass Halloween runs on a 5x3 grid with 10 paylines. The themes are Fishing, Halloween, Horror and Zombies. Wins come from symbols that line up left to right on adjacent reels, starting from the leftmost reel, and two matching symbols are enough to pay. The small-fish MONEY symbol carries a random cash value on each spin.
Choose this slot if you want cash collected during the bonus, not only line wins. Three, four or five SCATTER symbols start Free Spins. In that round, WILD appears on every reel and collects the MONEY values. A progress ribbon retriggers the round at the 4th, 8th and 12th WILD. Ante Bet lifts the total bet to 1.5x and turns off Buy Free Spins.

Know each rule
The worry this block removes: not knowing how a bonus round starts or how it plays out.
Spin and land three, four or five SCATTER symbols for 10, 15 or 20 Free Spins. WILD appears on all reels and collects MONEY cash values. The 4th, 8th and 12th collected WILD add 10 spins and lift the multiplier to 2x, 3x and 10x, capped at 3 retriggers.
Base game spinsExtra spins
Switch on the Ante Bet and the total bet rises to 1.5x, so A$2 becomes A$3. It increases the natural chance of landing SCATTER symbols and hitting Free Spins. While it is ON, Buy Free Spins is disabled.
Standard total betMore scatter chances
Choose Buy Free Spins to start the Free Spins round at once, for 100x the current total bet. At A$2 the cost is A$200. The option is disabled while the Ante Bet is ON.

Five steps, one session
After reading, you will know how a round moves from bet to final payout.
Pick your total bet from A$0.10 up to A$375 before the reels turn. Every payout on this page scales with that figure.
Wins form on 10 paylines, read left to right from the leftmost reel. Two matching symbols on adjacent reels are enough to pay.
Each spin, the small-fish MONEY symbol draws a random cash value from 2x to 2000x your total bet. Those values are set by chance, not by your choices.
Three Scatter symbols give 10 Free Spins, four give 15 and five give 20. Wild appears on every reel and collects visible MONEY values each spin.
Set a money limit before the first spin and stop when you reach it. The result of a session cannot be known in advance.
Decide your budget before the first spin, because the timing of the bonus round is not known in advance. It may appear early or after a long run of base game spins, and nobody can predict which. Each session is random. The RTP of 96.06 is an average over a very large number of spins, so it does not describe what happens to you tonight.
Before you commit a bankroll, open the game rules and look for the RTP shown there. Only that screen confirms which version runs in this lobby, since versions of the same game can list different figures. The figures on this page apply to 96.06 only.
Treat the maximum win as a ceiling, not a target, when you choose your bet. Reaching the x2,100 cap is very rare, and no one can say in advance when it will happen. The cap scales with the stake, so a larger bet raises the money figure at that ceiling.
Before any spin
Casino Room lists what each mode costs and pays, so each choice rests on stated rules.
The demo needs no money and pays nothing. The real game needs a Casino Room account and a player aged 18 or over.

Four questions answered
These answers settle the top win, risk level, purchase and trigger before you play.
Big Bass Halloween pays up to x2,100 the total bet. At the highest bet allowed here, A$375, that comes to A$787,500. The example top bet of A$2 gives A$4,200 at the same multiple.
This slot runs at high volatility. High volatility means the wins are less frequent but can be larger when they land. How often the bonus comes cannot be known in advance.
Yes, the Free Spins round can be bought directly for 100x the current total bet. On the example top bet of A$2, that is A$200. The purchase is disabled while the Ante Bet is switched on.
Landing 3, 4 or 5 SCATTER symbols anywhere on the grid starts the Free Spins with 10, 15 or 20 spins. Switching on the Ante Bet raises the natural chance of landing SCATTER symbols, at 1.5x the total bet. Retriggers can add more spins during the round.
