How Big Bass Bonanza works
You need three or more matching symbols on one of 10 fixed paylines, starting from the leftmost reel. Low-paying symbols are card ranks, and higher pays come from fishing gear such as the rod, tackle box and dragonfly. Fish symbols carry random cash values, but those values can only be collected during free spins.
Free spins and the fisherman collect
Land 3, 4 or 5 scatter symbols to trigger 10, 15 or 20 free spins. During the feature the fisherman wild appears and collects the cash value of every fish on screen. Each fisherman also fills a meter:
- 4 fishermen: 10 more free spins and a 2x multiplier on collected values
- 8 fishermen: 10 more free spins and a 3x multiplier
- 12 fishermen: 10 more free spins and a 10x multiplier
The best results come when several fish and a fisherman land together late in the feature, with the 10x multiplier active. Without a retrigger, many bonus rounds end with a modest win, which is why the game is rated medium-high volatility.
RTP and volatility: what they mean for you
The standard RTP of 96.71% means the game is designed to pay back about $96.71 for every $100 bet over millions of spins, a house edge of 3.29%. That is slightly above the online average, but some casinos run lower RTP versions, so open the info screen to check. Medium-high volatility means wins in the base game are fairly regular but small; most of the value sits in the free spins. Compare it with other games in our highest RTP slots guide.
