How to play Big Bass Bonanza
- Set your stake. Minimum and maximum bets are configured by the casino.
- Spin. Wins are paid on 10 paylines according to the in-game paytable.
- Look for Scatters. 3, 4 or 5 Scatters trigger free spins.
Free spins and fish money symbols

3, 4 and 5 Scatters award 10, 15 and 20 free spins. During the feature, fish symbols carry cash values of up to 2,000x. When a Wild lands, it collects the value of every fish on screen.
Wilds are counted: every fourth Wild retriggers the feature with 10 more spins and a rising multiplier: 2x, then 3x, then 10x on the third retrigger.
RTP and maximum win
