On the 5x3 grid, a win forms when matching symbols land on one of 10 paylines. Two matching symbols are enough to pay, and every symbol pays from left to right on adjacent reels, starting from the leftmost reel. The fishing theme meets a Halloween setting with horror and zombie touches. Each spin is a single round, and every result is random, so nothing here shows what the next spin will bring.
Three, four or five Scatters on the reels start the Free Spins round. Inside it, Wild appears on every reel and collects the cash values of visible MONEY symbols on each spin. A progress ribbon fills with each collected Wild, retriggering spins and lifting the multiplier. The Ante Bet raises the total bet to improve Scatter chances, while Buy Free Spins starts the round directly.

Bonus rounds
After this section you will know how each bonus round starts and what changes inside it.
Three, four or five SCATTER symbols landing anywhere on the reels trigger 10, 15 or 20 free spins. WILD then appears on all reels and collects the visible MONEY cash values each spin. Each 4th, 8th or 12th collected WILD adds 10 spins, up to 3 retriggers.

Before any wager
This section settles what the demo shows you before any money goes on the line.
The reels turn in the demo with no money at stake, and it pays nothing. The real game needs a Mybet Casino account and players aged 18+.
Play for realScatter symbols land on different reels and positions with each spin, so the free spins round can arrive early or not at all in a session. Nobody can know in advance when the next trigger will fall. The result of one session is random whatever the RTP, and the high volatility of this game means the session can end well below or above the stake.
Each spin on the 5x3 grid pays across 10 paylines, starting from the leftmost reel. Which RTP version runs on this game is shown only in the game rules, so read those rules before the first spin.
Winning combinations on the reels pay from two symbols up to the game ceiling, set as a multiple of the bet. The maximum win of Big Bass Halloween is a ceiling, not a target, and no one can say in advance whether a session will come near it. The money amount depends on the stake you pick.
Big Bass Halloween FAQ
Handy when you are choosing a bet and want to know what the game pays.
Big Bass Halloween keeps the fishing theme of its series and adds Halloween, horror and zombie themes. Its maximum win sits below Big Bass Splash 1000, which is the version with the highest ceiling in the series.
Each spin can be staked from A$0.10 up to A$375 in total bet. The A$0.40 and A$1 bets used on this page are examples, not limits. Pick a lower stake to keep each spin small while you learn the grid.
You can start at the minimum bet of A$0.10 and learn the 5x3 grid and its 10 paylines before raising your stake. The paytable shows what each symbol pays at A$0.40, so you can read the payouts before you spin.
Three, four or five SCATTER symbols anywhere on the grid start Free Spins, with 10, 15 or 20 spins. WILD symbols then appear on all reels and collect the MONEY cash values, and the 4th, 8th and 12th WILD add 10 spins each, capped at three retriggers.
RTP is a long-run average, so it says nothing about how one session will end. The versions table lists each Big Bass version with its RTP in money per A$100 staked. Compare the rows to see which version returns more over the long run.
The maximum win is 2,100 times your total bet, which makes it a ceiling rather than a target. Its money value rises with the stake, so check the bet before you spin. Nobody can know in advance whether, or when, a win that size will land.
