Each spin lands on a fixed grid of five reels and three rows, and the theme blends fishing with Halloween horror and zombies. Ten paylines run across the grid, and a win needs two or more matching symbols that start on the leftmost reel and continue to the right on adjacent reels. The small fish cluster is the money symbol: each one carries a random cash value that changes on every spin.
Scatter symbols landing anywhere start Free Spins, with 10, 15 or 20 spins depending on how many appear. In that round, Wild symbols appear on every reel and collect all visible money values on each spin. The progress ribbon adds ten spins at the fourth, eighth and twelfth collected Wild, and the collection multiplier climbs to 2x, 3x and 10x. Retriggers stop after three.
The reels jump straight to free spins for 100 times the total bet, which is A$50 at the A$0.50 top bet.

Five steps, one round
Sportybet Casino shows each step of a round before you put money on the reels.
The reels stay still until you set a total bet from A$0.10 to A$375. Every win scales with that bet, and this page uses A$0.20 and A$0.50 as examples.
Wins form when matching symbols line up on adjacent reels, starting from the leftmost reel, across 10 paylines. Two matching symbols are enough to pay on this 5x3 grid.
On every spin, each small-fish MONEY symbol carries a random cash value of 2x to 2000x total bet. Scatter symbols anywhere on the grid count toward the bonus.
Three, four or five SCATTER symbols anywhere on the grid start Free Spins with 10, 15 or 20 spins. WILD symbols then appear on every reel and collect visible MONEY values.
Nothing on the reels shows when a session ends, so set a limit before spinning. If play is hard to control, call the National Gambling Helpline on 1800 858 858.

Scatters just landed
After reading, you will know how each mode starts and what changes once it runs.
3/4/5 SCATTER symbols anywhere on the reels start 10/15/20 free spins. WILD appears on all reels and collects all visible MONEY cash values each spin. The 12-cell progress ribbon retriggers +10 spins at the 4th/8th/12th collected WILD, raising the MONEY-collection multiplier to 2x/3x/10x, capped at 3 retriggers.
Base gameFree spins
SCATTER symbols land more often on the reels while Ante Bet is ON, which raises the total bet to 1.5x. The natural chance of hitting Free Spins goes up too. The toggle disables Buy Free Spins while it stays ON.
Standard betMore scatter chances
The reels go straight into the Free Spins round when you buy it for 100x current total bet. While Ante Bet is ON, this purchase is disabled. The bought round works like any other Free Spins round, with WILD collecting and retriggers.
Before any spinFree Spins round
Symbols land on a fixed 5x3 grid, and 10 paylines decide what pays. All symbols pay left to right, on adjacent reels starting from the leftmost reel. On each spin, the small-fish MONEY symbol carries a random cash value of 2x/5x/10x/15x/20x/25x/50x/2000x total bet.
Bet chosenLine wins
Each spin on the 5x3 grid lands a fresh set of symbols, and nothing on the reels shows when the Free Spins round will start. How often the bonus comes is not known in advance. The result of one session is random, whatever RTP the game runs at, so a long quiet stretch or a fast bonus says nothing about the next spin.
The reels show symbols, paylines and wins, but never which RTP version the game runs. That detail sits only in the game rules, so read them before you start a session. Sportybet Casino states the version there, and the RTP figures in money follow from it.
The top prize sits at the far edge of what the reels can pay, and only a rare run of spins gets close to it. The maximum win is a ceiling reached very rarely, so read it as the most the game can pay, not as a result to expect from any session.
Four questions, short answers
After this, you will know the bets, the bonus cost and the volatility before you spin.
Big Bass Halloween has a 5x3 grid, 10 paylines and four modes, all explained on this page. Check the paytable at the A$0.20 example bet before you choose a stake. Each mode explains how a round runs, so the rules are clear before any stake is placed.
Yes, the Free Spins round can be bought directly for 100x the current total bet. At the A$0.50 example top bet that costs A$50. The buy is disabled while Ante Bet is switched on.
The minimum bet is A$0.10 and the highest bet allowed here is A$375. The example bets on this page are A$0.20 and A$0.50. Ante Bet raises the total bet to 1.5x, so A$0.50 becomes A$0.75.
Volatility is high, so payouts come in uneven bursts rather than steady small wins. The maximum win is x2,100 the bet, or A$787,500 at the A$375 top bet. How often a bonus lands cannot be known in advance.
Players must be 18+. For help, call the National Gambling Helpline on 1800 858 858. To self-exclude, use BetStop, the national self-exclusion register.
Set a budget before you start and treat it as the most you will lose. Stop when it is gone, even if a bonus round looks close.
Pick your stop point before you begin, and keep it after a win too. A big win is no reason to play on.
Set the deposit and loss limits on your account before you play. Lower them whenever a session costs more than you planned.
Take a break when the game stops being fun, and self-exclude through BetStop if playing is no longer under your control.
