Bonus Rounds & Free Spins

8 

Free Spins

If you collect 3 or more scatters on any position on the reels this will trigger the bonus game with Free Spins. When this feature is activated every reel with a Scatter symbol will give you a random number of free spins up to 6/reel, which will be added together. The sum of these will be the total number of free spins that are awarded for the bonus game. So if, for example, a reel awards 4 free spins, another gives 5 and another 6 free spins, you will get 15 free spins in total.

Other than that, if the bonus game the wild symbol always expands and if during each free Spin one or more Wild lands on reels they will expand and trigger 1 respin.

Overall Rating

8.2
Big Fin Bay is a decent callback to retro 90s game design. The fishing theme is distinct and the gameplay is easy to pick up for beginners. There is perhaps a lack of features but that can be viewed as a positive if you’re looking for a straightforward, easy-to-grasp experience. On top of that, you have a shot at a very good max exposure, which is always good!
