Symbols land on a 5x3 grid, and a win needs only two matching symbols that pay in a row from the leftmost reel across one of 10 paylines. The theme mixes fishing with Halloween, horror and zombies: lifebuoy rings, fishing hooks, a crow and tackle boxes sit beside the card symbols 10, J, Q, K and A. The small-fish cluster is the MONEY symbol, and each spin it carries a random cash value.
Three, four or five scatter symbols anywhere on the grid start free spins, for 10, 15 or 20 spins. In that round the wild appears on all reels and collects visible small-fish cash on each spin. A 12-cell ribbon adds 10 spins at the 4th, 8th and 12th collected wild, and lifts the money multiplier to 2x, 3x and 10x, up to three retriggers.
Extra spins, more cash
Unsure when the bonus starts? Each mode below states how it begins and what it changes.
Three, four or five SCATTER symbols land anywhere and start 10, 15 or 20 free spins. WILD collects visible MONEY cash on each spin. At the 4th, 8th and 12th collected WILD, 10 spins are added and the multiplier rises to 2x, 3x and 10x. Retriggers stop after 3.
Base Game spinsRetriggered free spins
SCATTER symbols land more often when Ante Bet is ON, which raises the natural chance of hitting Free Spins. The toggle lifts the total bet to 1.5x. While it is ON, Buy Free Spins is disabled.
Standard total betMore scatter chances
The reels open straight into Free Spins once you buy it, for 100x the current total bet. The round then plays out with the same WILD and MONEY rules as Free Spins won on the reels. Buy Free Spins is disabled while Ante Bet is ON.
Before any scattersInstant Free Spins
Each spin fills the fixed 5x3 grid, and wins run left to right across the 10 paylines. The small fish cluster MONEY symbol carries a random cash value of 2x, 5x, 10x, 15x, 20x, 25x, 50x or 2000x total bet.
The first spinWins and cash
The buy price is 100 times the total bet, so at the A$10 example bet the Free Spins round costs A$1,000.

Across the reels, the game pays back a share of staked money over time, and the table turns that share into cash per A$100 staked. The version running at Crownplay is listed in the game rules.

Inside the free spins
These screens show the grid, the money values and the progress ribbon before you decide on a stake.
Big Bass Halloween
Crownplay sets out each round in plain steps, so every limit is visible before any stake goes down.
Before the first spin, you pick a total bet from A$0.10 up to A$375. Every payout scales with that stake, so a A$0.20 bet and a A$10 bet pay different amounts.
Symbols pay from the leftmost reel across 10 paylines, on adjacent reels only. Two matching symbols are enough to pay, so a win can form early.
Each spin, the small fish money symbol lands with one cash value from 2x to 2000x the total bet, and it pays that value in cash.
Three, four or five scatters start the free spins with 10, 15 or 20 spins. Wild symbols then appear on every reel and collect the visible money values on each spin.
Each round ends when the reels stop, so set your limit before the first spin. Every outcome is random and cannot be predicted.
Each spin lands symbols at random on the 5x3 grid, so how often Free Spins arrive cannot be known in advance. Scatter symbols on one spin decide the trigger, and no run of empty spins signals the next one. Whatever the RTP of 96.06, the result of one session stays random, because the RTP describes returns across very long play, not one visit to the lobby.
The reels stop on one result, and the RTP version behind that result is shown only in the game rules. Open that section before the first spin and read which version is listed. The rules give the figure the game runs on, so it is the place to check before a bet is placed.
Top combinations on the reels can reach the maximum win of this slot, but that ceiling is reached very rarely. The figure marks the upper edge of the game, not an expected result, and it says nothing about how any single session will end.

Read this before your first spin, when you need the maximum win, the bonus price or the RTP.
The reels can pay up to x2,100 the total bet. At a bet of A$10 that is A$21,000, and at the highest bet of A$375 it is A$787,500.
Buying the Free Spins round starts it directly from the base game, for 100x the current total bet. On a A$10 bet that costs A$1,000. The purchase is disabled while Ante Bet is switched on.
Each spin on the reels can be as low as A$0.10, so the first rounds stay small. At A$0.20 the paytable shows what every symbol pays, and the money values scale with the bet you choose.
Spins on the reels return 96.06 percent of every A$100 staked across a very large number of rounds. This is the only RTP of the game, and it describes an average over many rounds, not the result of one session.
