Learn the game before you place a bet

Pick this slot if you want a fishing game with a horror twist. Big Bass Halloween 3 runs on a 5x3 grid with 10 paylines that run left to right. A win needs only two matching symbols on a payline. Symbols include Zombie Van, Axe and Zombie Bass, plus card symbols A, K, Q and J. Fish symbols show random money values each spin, visible but not collectible in the base game.

Pick it for bonus rounds built on fish trackers. Three, four or five Scatter symbols start Free Spins of 15, 20 or 25 spins. Each Wild collects the money values visible on the fish. Every fourth Wild of one colour adds 10 spins and climbs the multiplier 1x, 2x, 3x, then 10x. Super Free Spins retrigger on three Wilds of any colour.

Five steps per round

Steps of one Big Bass Halloween 3 round

Most newcomers fear they will miss what happens after the first spin, so each step explains it.

  1. A$0.10 to A$375 range

    Choose a bet from A$0.10 up to A$375 before the first spin. Every payout and feature cost on this page scales with the bet you pick.

  2. Line up matches across the paylines

    Look for matching symbols on the 10 paylines, which run left to right across the 5x3 grid. A payline pays from as few as 2 matching symbols.

  3. When you add 1.5x

    Watch the Ante Bet, which costs 1.5x the bet and turns off the buy options. Money values on the fish stay visible but cannot be collected in the base game.

  4. Free Spins by purchase

    Land 3, 4 or 5 SCATTER symbols to start 15, 20 or 25 free spins. Or use Buy Free Spins to start the round at once.

  5. Helpline when play turns harmful

    Set your limit before the first spin and stop once you reach it, win or lose. Need help with play? Call the National Gambling Helpline on 1800 858 858.

Purchase fees and the ante

Check the bonus buy price first: it is a fixed multiple of the bet, at A$10 Free Spins costs A$1,000 and Super Free Spins A$3,000.

How do the free spins begin?

Wondering how many spins a trigger gives and whether they can grow.

When SCATTER symbols land

Three to five SCATTER symbols start it with 15, 20 or 25 free spins. Each WILD collects visible MONEY values, and every fourth WILD of one colour adds 10 spins and lifts the multiplier from 1x to 2x to 3x to 10x. Wins cap at 5,000x the total bet.

Base gameExtra free spins

Three combined, not four per meter

Three or more SCATTER symbols trigger it naturally, and it runs on the same mechanics as Free Spins. The retrigger needs only three WILD FISHERMAN of any colour, counted across both trackers combined, instead of four of one colour in a single meter.

Base gameSuper Free Spins

Grid and paylines left to right

The game runs on a 5x3 grid with 10 paylines read from left to right. Fish symbols show random MONEY values on each spin. Those values are visible but not collectible in this mode.

Before your first session on Big Bass Halloween 3

Before you set a budget, know that the bonus round in Big Bass Halloween 3 cannot be timed. How often it appears is not known in advance, and the result of one session is random, whatever the RTP. Past spins say nothing about the next bonus. A long dry run is no sign of a hit, so set your budget for the session rather than for one feature.

Before you start, check which RTP version this site runs, because only the game rules show it. Different versions of a slot can pay back different shares of the stake. The version this page follows is the one listed in the figures, and the game rules show which one is in play.

Plan around the maximum win as a ceiling, not as a target. The top prize of Big Bass Halloween 3 is a fixed multiple of the bet, and it is reached very rarely. Read it as the upper limit of what the game can pay on one bet.

Account and age requirements for paid play

This block settles whether to try the game with no money before you deposit or play for real stakes.

Pick the demo to learn the game with no money, since it pays nothing. Real-money play needs a Star Casino account and a player aged 18 or older.

Play for real

How much are you prepared to lose?

You must be 18+ to play. Call the National Gambling Helpline on 1800 858 858, or register with BetStop, the national self-exclusion register.

Fix your loss amount first

Set the amount you can afford to lose before you open the game. A budget made in advance keeps the decision with you.

Stopping point before spinning

Choose your stopping point before the first spin and keep it after a win too. A win can tempt you to chase the next spin.

Account caps that stop losses

Set deposit and loss limits in your account before you play. Limits chosen in a calm moment are easier to keep during a session.

Stepping away while ahead

When the game stops being fun, pause and step away, even when you are ahead. If a pause does not help, self-exclude.

Read this before you set a bet, when the paytable and RTP still feel unclear.

How do I learn Big Bass Halloween 3 before betting real money?

Learn the rules before you stake real money. The paytable is shown at A$5, the grid runs 5x3 with 10 paylines left to right, and two matching symbols already pay.

What is the maximum win on Big Bass Halloween 3?

Decide your stake with the top win in mind. The maximum win is x5,000 of the total bet, so an A$10 bet caps at A$50,000. At the A$375 maximum bet, the ceiling reaches A$1,875,000.

What is the RTP of Big Bass Halloween 3 and its versions?

Compare the versions by RTP before you choose one. Big Bass Halloween 3 returns 96.50% over a long run, and the related releases range from 96.50% to 96.52%, so the gap between them is small.

How volatile is Big Bass Halloween 3 for a player?

Plan your budget for a high volatility slot. Results swing widely, and nobody can know in advance how often the bonus comes or how a session will end. Volatility here is high, so bigger swings are part of the game.

What bets can I place on Big Bass Halloween 3?

Pick a bet between A$0.10 and A$375 before you spin. A$5 and A$10 are only examples used on this page, and the Ante Bet costs 1.5x the stake, so A$10 becomes A$15.
