Big Bass Bonanza RTP explained
Pragmatic Play lists the Big Bass Bonanza RTP at 96.71%. That is a little above the 96.50% you see on many newer Pragmatic slots. The game is also offered with lower settings, so the figure at your casino can be lower. Check it in the game info screen.
Volatility is where sources differ. We found it rated low, medium and high. In practice the max win is 2,100x, which is modest, and the value is spread over more rounds than in games like Gates of Olympus 1000.
How the game works
Big Bass Bonanza is a 5x3 fishing slot with 10 paylines. Fish symbols can land with cash values on them. In the base game they pay only as normal symbols, so the real action is in the bonus.
Free spins and the fisherman
Three, four or five scatters give 10, 15 or 20 free spins. During free spins the fisherman wild collects the value of every fish money symbol on screen. Fish values go up to 2,000x.
Every fourth fisherman retriggers the round with 10 more spins. The first retrigger adds a 2x multiplier to collected values, the second 3x and the third 10x. Reaching the 10x stage is the main route to the top win.
Bigger Bass Bonanza and other versions
The game started a long series. Bigger Bass Bonanza uses a 5x4 grid, 12 paylines and a 4,000x max win with the same 96.71% RTP. Find more Pragmatic games and their RTP on our Pragmatic Play slots page.
