What are the main Big Bass Bonanza features?
This game has a number of features, including a wild, scatter, money symbol feature, and free spins. The fisherman is the wild and can substitute for any symbol except the scatter. The scatter symbol is a fish jumping out of the water on a hook.
The money symbol is a pile of fish and it acts as a multiplier. It takes a random value at the start of each round, which can be won in the base game and during the free spins round.
Landing three or more scatter symbols will activate the free spins round in this game. Players will receive 10 free spins if they land three scatters, 15 for four scatters, and 20 for five scatters.
If any wilds land during this round, they are collected. Every fourth wild will retrigger the round and award 10 more free spins. This can happen up to three times, and the multiplier of the money symbol will increase by 2x for the first trigger, 3x for the second, and 10x for the third retrigger.

Our top tips for playing Big Bass Bonanza
Here are our Big Bass Bonanza slot top tips:
- Set a sensible bankroll: It’s easy to get carried away when you’re playing, so setting a bankroll will give you a method of assessing when it’s time to stop.
- Don’t chase losses: Although the outcome of slots is completely random, it is possible to have losing streaks. When this happens, it can be tempting to bet more to try and get a win. However, the best approach is to take a break, as betting more is not a guarantee of winning.
