How Bigger Bass Bonanza works
Wins pay on 12 fixed paylines across a 5×4 grid. The Fisherman is the wild and substitutes for paying symbols. Money Fish symbols carry random cash values, and the free spins round is where the Fisherman collects them.
Free spins and the multiplier ladder
Land 3, 4 or 5 scatters to win 10, 15 or 20 free spins. During the feature, every Fisherman wild that lands collects the value of every Money Fish on screen. Every 4th Fisherman collected retriggers 10 more spins and raises the multiplier on collected values (reported up to 10x on the final level). The biggest wins come from reaching the higher levels with plenty of fish on the reels.
Bigger Bass Bonanza vs Big Bass Bonanza
The original uses a 5×3 grid with 10 paylines and a 2,100x max win. Bigger Bass Bonanza adds an extra row, two more paylines and almost doubles the max win to 4,000x. Read our Big Bass Bonanza review for the original.
RTP and volatility: what they mean for you
The top RTP is 96.71%, a house edge of about 3.3%, which is good for a Pragmatic slot. Casinos can also run 95.67% or 94.62% versions, so check the info screen. Sources rate it high or very high volatility: the base game is quiet and most of the value sits in the free spins.
