Big Fin Bay Features

Big Fin Bay features are extremely well-thought and diverse, creating unique gameplay for everyone who enjoys sea fishing and seeks exciting rewards.

You have the lucrative Mystery Wild and Expanding Wilds and the Bonus Game, which is reasonably lavish on free spins. Read below for a detailed description of each Big Fin Bay feature.

Mystery Wild

The Mystery Wild feature is a great way to form winning combinations. The Mystery Wild symbols appear randomly during your game and can turn up to 3 reels into full wilds. Note, however, that the scatter symbol is disabled while this feature is on.

Expanding Wilds

You can activate the Expanding Wilds feature when you land a wild in a winning combination. The idea is that the wild will expand to fill the entire reel and enhance the probability of hitting a winning combo.

Bonus Game Feature

Big Fin Bay’s Bonus Game feature is skillfully crafted for your maximum enjoyment and success. Landing 3+ Anchor scatter symbols triggers this feature, which can award you with as many as 36 spins at the start.

Further, each wild expands to turn the reel into a full wild, rewards a respin, and lengthens the reel by adding more symbols. All of these functions serve to increase your winning potential.
