How Big Bass Bonanza plays

Big Bass Bonanza is the fishing slot that started one of the most copied series of recent years. It was developed by Reel Kingdom and is distributed by Pragmatic Play. The game runs on five reels, three rows and 10 lines.

The base game is a simple line slot. The feature is the free spins, triggered by scatters. During the free spins, fish symbols carry cash values and the fisherman wild collects the value of every fish on screen when he lands. Every fourth fisherman collected adds more free spins and raises the multiplier on what later fishermen collect, so a feature that keeps landing fishermen grows quickly.

Volatility in practice

Listed as medium-high. The base game pays small line wins, and almost all of the value sits in the free spins. Whether a feature pays well depends on fishermen and fish landing together, so many features end small. The 2,100x ceiling is modest compared with the later versions.

RTP settings

The top setting is 96.71%, and public listings show 95.67% at some casinos, roughly €10 less per €1,000 wagered. Check the info panel in the game client to see which setting your casino runs. The sequels, such as Big Bass Splash and Big Bass Bonanza 1000, have their own settings.
