Pragmatic Play · 2023
Big Bass Halloween is a high volatility video slot from Pragmatic Play on a 5x3 grid. This page covers figures, bonus rounds and costs before your first spin.
Symbols land on a 5x3 grid, and wins come from 10 paylines. Every symbol pays left to right, starting from the leftmost reel and running across adjacent reels, and two matching symbols are enough for a win. The theme mixes fishing with Halloween, horror and zombies, and the reels show a fishing hook, a tackle box and a crow alongside the card symbols 10, J, Q, K and A.
Three scatters anywhere on the reels start Free Spins, and Wilds collect the cash values of visible small fish symbols. At the 4th, 8th and 12th collected Wild, the round adds spins and raises the multiplier, and retriggers stop after three. The Ante Bet raises the total bet and makes scatters land more often, and it switches off Buy Free Spins while on.

Five steps, one round
After this, you will have walked through a full round from bet to free spins.
The reels stay still until you set a bet between A$0.10 and A$375. Every payout on the grid is a multiple of the bet you choose.
Wins start on the leftmost reel and run right, one adjacent reel at a time. Two matching symbols are enough to pay on any of the ten paylines.
Each spin, the small fish cluster lands with a random cash value from 2x to 2000x your total bet. Its value is what Free Spins collects later.
Three, four or five SCATTER symbols anywhere on the grid trigger 10, 15 or 20 free spins. WILD then appears on all reels and collects the visible MONEY values each spin.
Reels keep turning spin after spin until you stop, so set a limit before the first spin. If play stops feeling fun, call the National Gambling Helpline on 1800 858 858.
Feature guide
Read this before your first spin, when you want to know how a bonus round begins.
3, 4 or 5 SCATTER symbols give 10, 15 or 20 spins. WILD appears on all reels and collects visible MONEY cash each spin. A 12-cell ribbon retriggers +10 spins at the 4th, 8th and 12th WILD, up to 3 times, with MONEY multipliers of 2x, 3x and 10x.
Base game spinsBonus spins
On the reels, the Ante Bet increases the natural chance of landing SCATTER symbols and hitting Free Spins. Switching it on raises the total bet to 1.5x. With A$10 as the top example bet, the total bet becomes A$15.
Normal betHigher scatter chance
Buy Free Spins starts the Free Spins round directly for 100x the current total bet. It is disabled while the Ante Bet is ON. At the example top bet of A$10, the purchase costs A$1,000.
Base gameFree Spins round
Each spin lands symbols on the 5x3 grid, and wins run along 10 paylines, left to right on adjacent reels from the leftmost reel. The small-fish MONEY symbol gets a random cash value of 2x, 5x, 10x, 15x, 20x, 25x, 50x or 2000x the total bet on each spin.
Game lobbyWins and cash
Three views, one round
Before you bet, see how the base game, a win and free spins look on screen.
Reels stop at random on every spin, so the free spins trigger follows no schedule. How often the bonus round comes is not known in advance, and the result of one session is random whatever the RTP. Long sessions can run without a single trigger, and short ones can open with one.
Each spin lands on the same 5x3 grid, but the RTP version behind it is a separate question. Which RTP version we run is shown only in the game rules, so check there before you start spinning. The table above shows what that means in money.
Symbols pay left to right from the leftmost reel, and the biggest hits reach the top multiple of the bet for Big Bass Halloween. That ceiling is reached very rarely, so read the maximum win as a limit, not a target.
Practice mode
Here is what the demo gives you, and what the real game needs before your first bet.

Big Bass Halloween basics
Royalreels explains the numbers first, so you can decide before you bet.
Three, four or five Scatter symbols anywhere on the reels start the free spins: 10, 15 or 20 spins. During the round, every 4th, 8th and 12th Wild collected adds 10 more spins, up to three times.
This slot has one RTP version, 96.06 percent. Other Big Bass titles run at 96.50 to 96.52 percent, so the RTP can differ between games of the series.
The paytable shows what each symbol pays at a bet of A$0.40, so the payouts can be read before the first spin. The minimum bet is A$0.10, so a first session can start small.
The top win is x2,100 of the total bet. At the example top bet of A$10 that is A$21,000, and at the highest bet of A$375 it is A$787,500.
Big Bass Halloween has high volatility. Wins can vary a lot in size from spin to spin. How often the bonus comes cannot be known before a session.
