Pragmatic Play · 2025
Big Bass Halloween 3 is a high volatility 5x3 video slot from Pragmatic Play. Here are the figures, bonus modes and paid feature costs.
The demo is free. The real game needs an account and players aged 18+.
If you want a slot that mixes fishing with zombies, Big Bass Halloween 3 is a video slot on a 5x3 grid. Wins pay along 10 paylines read from left to right, and a line can pay from just 2 matching symbols. Its symbols include Zombie Bass, Zombie Van and the card ranks A, K, Q and J. Each spin, the fish symbols show random money values, visible but not collectible.
If you are comparing it with other Pragmatic Play titles, look at the bonus first. Free Spins start on 3, 4 or 5 Scatter symbols. Two Wild Fisherman trackers collect the visible money values. Every fourth Wild of one colour adds 10 spins and steps up the multiplier. Super Free Spins retrigger on 3 Wilds of any colour.

Round guide
Unsure what your bet does before the reels stop? Here is the round, step by step.
Set your bet anywhere from A$0.10 to A$375 before the reels start. Every win scales with the stake, so A$0.20 and A$10 bets pay in proportion.
Check the 10 paylines that run left to right across the 5x3 grid. Two matching symbols in a row on a line pay, so a win starts at the leftmost reel.
Watch the fish symbols, which show random money values on each spin. In the base game those values can be seen but not collected, so they add nothing to the win.
Land three, four or five SCATTER symbols on the reels to trigger Free Spins. Three give 15 spins, four give 20 and five give 25.
Set a session limit before the first spin and stop once it is reached. If play stops feeling fun, the National Gambling Helpline is 1800 858 858.
During Free Spins
Useful once the bonus starts, when the trackers and multipliers start counting.
Each buy costs a fixed multiple of your bet, so the price moves with the stake, as the figures show at the top example bet.

| Buy Super Free Spins at 300x | x300 · A$3,000 | – |
Return to player shows how much of the staked money comes back over time. For every A$100 staked, the long-run average return is A$96.50. The version we run is shown in the game rules.

Before you trigger
Read on and you will know how each mode starts and what it holds.
Land 3, 4 or 5 SCATTER for 15, 20 or 25 free spins. Two WILD FISHERMAN trackers run. Each WILD collects a visible MONEY value. Every 4th WILD of one colour adds 10 spins and lifts the multiplier from 1x to 10x. Wins stop at 5000x the total bet.
Base Game reelsMultipliers and spins
Three or more SCATTER symbols start it, with the same mechanics as Free Spins. A retrigger needs only 3 WILD FISHERMAN of any colour, counted across both trackers together. Standard Free Spins need 4 of the same colour in each meter.

The demo needs no money and pays nothing. The real game needs an account at Millionaire Casino and you must be aged 18 or over.
Play for realDeciding how long to stay on Big Bass Halloween 3 starts with one honest point. How often the bonus round comes is not known in advance. The result of one session is random, whatever the RTP shown on the rules page.
Deciding whether the RTP suits you begins with the game rules. The RTP version in use is shown only there, so check it before the first spin, and read the figure as a long-run average across many rounds rather than a promise for your session.
Chasing a big result on Big Bass Halloween 3 means knowing its ceiling first. The maximum win is x5,000 the bet, and it is reached very rarely, so treat it as a limit on the payout rather than a target for any session.
This game is for players aged 18+. Get support from the National Gambling Helpline on 1800 858 858, or self-exclude through BetStop.
Set the amount you can afford to lose before the first spin, and treat it as the limit for the session. Stop when it is gone.
Choose your stopping point before you spin, and keep to it even after a big win. A win does not change the limit you set.
Set deposit and loss limits in your account before you play. They cap what goes in and what you can lose.
Take a break as soon as the game stops being fun. If play no longer feels in your control, self-exclude through BetStop.

Clear facts for players
Millionaire Casino puts the rules and the costs in plain view before you bet.
Bets run from A$0.10 to A$375 per spin. The examples on this page, A$0.20, A$5 and A$10, are for illustration and are not the limits. A$375 is the highest bet allowed here.
The maximum win is 5,000 times your total bet. At the highest bet of A$375, that is A$1,875,000. Nobody can know in advance whether a session reaches it.
Read the rules on this page before your first real spin: the 5x3 grid, the 10 paylines, the three modes and the paid features. Use them to judge a bet from A$0.10 upward, since the paytable on this page uses A$0.20.
Big Bass Halloween 3 has high volatility. That means the size of wins can vary a lot from spin to spin, so a session can end far from where it started. Until you play, how a session goes stays unknown.
