Our rating:
  • A nice-looking game with enjoyable music
  • Base game has several wild features for extra wins
  • Free spins lets you add extra ways to win

Big Fin Bay slot comes to you from Thunderkick and it has a nautical theme catching fish. Sure, the graphics aren’t the best, but overall it’s a great-looking game that’s bright, cheerful and has some fun music too that doesn’t seem to get annoying. That’s quite an achievement. To start with on the reels you have 5,040 ways to win, but don’t worry as this can increase to 117,649 during the free spins bonus as we’ll soon see. All you need is a winning combination from left to right using the base symbols which are as follows, ranked in ascending order based on their value:

  • 9 or 10
  • Jack
  • Queen
  • King
  • Ace
  • Blue Fish
  • Green Fish
  • Purple Fish
  • Red Fish
  • Captain

You also have a wild symbol, shown as a golden fish, which substitutes for all other symbols in a winning combination apart from the scatter.

Big Fin Bay Slot Bonuses and Features

Expanding Wilds. If you get a wild symbol in a win, it will then expand to fill the entire reel.

Mystery Wild. This is a randomly triggered feature in the base game, where up to 3 reels can become fully wild for lots of extra wins. No scatter can appear in this feature though.

Free Spins Bonus. For this you need 3 or more scatter symbols anywhere on the reels, shown as a golden anchor. The number of free spins will vary, with each scatter symbol giving you up to 6 free spins each. In this bonus, whenever a wild symbol lands it will always expand and give you a respin. In the respin, an extra wild symbol will be added to that reel as well, increasing the number of ways to win and this will remain so until the end of the bonus. The maximum number of symbols you can get on a reel is 7, and doing this will give you another 3 free spins.
