Pragmatic Play · 2023
Big Bass Halloween is a high-volatility 5x3 fishing slot from Pragmatic Play and Reel Kingdom, and this page lays out its figures, payouts, free spins and bet rules before you spin.
The demo is free; the real game needs an account and you must be 18+.
Symbols land on a 5x3 grid, and a win pays when matching symbols sit on adjacent reels from the leftmost reel. Two matching symbols are enough for a win. The theme blends Fishing, Halloween, Horror and Zombies: hooks, tackle boxes and a crow share the reels with the card symbols 10, J, Q, K and A, and a small fish cluster carries a random cash value on each spin.
Three, four or five Scatter symbols anywhere start Free Spins with 10, 15 or 20 spins. Inside Free Spins, Wild appears on all reels and collects the cash of visible money symbols. Each 4th, 8th and 12th Wild collected on the ribbon adds 10 spins and raises the multiplier. Ante Bet adds a chance of Scatters, but it turns Buy Free Spins off.

How a round runs
Read this when you are about to load the reels and want to know what each tap does.
Set your stake per spin anywhere from A$0.10 up to A$375. That range holds at every level of play, and each spin costs the stake you choose.
Ten paylines run left to right from the leftmost reel, and every symbol pays on adjacent reels. Line up matching symbols starting there and the win lands on screen.
Reels carry Wilds and a small fish MONEY symbol worth a random cash value each spin. Three, four or five Scatters anywhere launch the Free Spins round.
Landing three or more Scatters awards ten, fifteen or twenty spins. Wilds that appear on every reel sweep up the visible MONEY values as the ribbon fills.
Big Bass Halloween spins as long as you let it, so fix a loss limit and a time check before the first spin. Walk away when either one arrives.
Four modes to know
Wondering when free spins start and what a bigger bet changes?
3, 4 or 5 SCATTER symbols anywhere start Free Spins: 10, 15 or 20 spins. WILD appears on all reels and collects visible MONEY cash values. The 12-cell ribbon adds 10 spins at the 4th, 8th and 12th collected WILD, raising the MONEY multiplier to 2x, 3x and 10x. Max 3 retriggers.
Base Game spin10-20 free spins
Switch on the Ante Bet and the total bet rises to 1.5x. This raises the natural chance of landing SCATTER symbols and hitting Free Spins. While ON, Buy Free Spins is disabled.
Base Game betMore Scatter chances
Buy Free Spins starts the Free Spins round straight away for 100x the current total bet. At the A$1 example bet, that is A$100. It is unavailable while the Ante Bet is ON.
Base Game screenInstant Free Spins
Base Game uses a fixed 5x3 grid with 10 paylines. All symbols pay left to right on adjacent reels, starting from the leftmost reel. Each spin, every small fish MONEY symbol carries a random cash value of 2x, 5x, 10x, 15x, 20x, 25x, 50x or 2000x the total bet.
Game lobbyMoney symbol cash
Spinning the reels tells you nothing about when the next round of free spins lands, or how many you will see in a sitting. Scatters appear on their own schedule, not on yours. A high return to player is an average across millions of spins, so one session can end far above or below it. Treat every spin as an independent draw.
Which build of this slot sits behind the lobby is not something a preview can settle. The version in play is stated inside the game rules menu, and it is the only statement worth trusting. Before you raise your stake, open that menu and read the figure printed there.
The headline maximum of x2,100 marks a ceiling, not a target. It needs a full screen of wilds working with the biggest collectible values and the top multiplier tier in the same round. Most players finish a session without seeing anything close, and that is the ordinary course of play.
Every spin draws on your balance. You must be 18+ to play. For help in Australia, call the National Gambling Helpline on 1800 858 858 or join BetStop, the self-exclusion register.
Every spin of Big Bass Halloween takes from your budget, so fix the amount in cash before the first reel turns.
Scatter symbols can land on any spin, so set a stop point before the reels turn and keep to it after a win.
A run of dry reels can drain a balance quickly, so set deposit and loss limits in your account before the first spin.
Reels that stop being fun are the signal to take a break, and BetStop lets you self-exclude if the urge to chase keeps returning.
Big Bass Halloween FAQ
Settles whether you can try the game first, how swings feel, the top win and which bets apply.
Each spin of Big Bass Halloween can be placed from A$0.10, so that is the cheapest way to learn a round. The paytable on this page uses A$0.40 as its example bet. Raise the stake only after you know how Wild and Scatter symbols behave.
Each spin on the 5x3 grid runs at high volatility, so payouts can come in long gaps and then arrive in bursts. No one can tell in advance when a burst will land.
Wins on the reels can reach x2,100 times the bet, which is A$2,100 at the top example bet of A$1. At the highest bet allowed here, A$375, the same multiple reaches A$787,500.
Reels spin at a minimum bet of A$0.10 and up to a maximum of A$375, the highest bet allowed here. Switching on Ante Bet raises the total bet to 1.5 times, so A$1 becomes A$1.50.
