Big Fin Bay Slot (Thunderkick)

Big Fin Bay Slot (Thunderkick)The fishing theme is not a new thing, and this has been used many times before by game developers.

Thunderkick has decided to embrace it as a source of inspiration for their slot, titled Big Fin Bay.

On the shore of this fishing village, the developer has included saltwater fish, alongside an unusual setup.

Here are more details about Big Fin Bay:

Game Set-Up

Big Fin Bay has 6 reels and as many as 5,040 ways to win. The ways to win can increase to as many as 117,649 ways during free spins.

It’s a slot with great potential, and among its features are an expanding Golden Marlin Wild, Reel Expansions, Anchor Scatters, as well as Free Spins.

Betting and Prizes

Depending on your gaming budget, you can place bets from as low as $0.10 to as high as $100 per spin.

Big Fin Bay has massive payout potential, and the game can reward you with as much as 15,040x the stake.

However, these huge prizes are accompanied by very high volatility, but the RTP of 96.14% helps in taming this high risk.

Big Fin Bay Slot Features

Big Fin Bay uses an unusual set-up that consists of between 2 to 7 symbols on its 6 reels.

However, with the help of some of its features (free spins), these can expand to as many as 117, 649, on a 6x7 reels layout.

Just like is the case with many other modern slots, the wild symbol (Golden Merlin) is present, and it serves as a substitute for just one combo.

When it expands, the wild will offer a higher chance of landing much bigger prizes for the round.

It can only act as a replacement while forming new winning combos.

Mystery Wilds are the other great features that Thunderkick has used. With their help, you can transform between 1, and 3 regular reels into full wilds.

This is possible even with a single appearance of the Mystery Wilds.

Last but not least is my favourite feature, the free spins!

On Big Fin Bay, the free spins have a massive advantage, and with between 3 and 6 of such, you can get as many as 36 free games.

Theme & Design

Big Fin Bay will take you on a tour to the bay that appears between two fishing villages.

The surrounding area is dotted with white houses with high cliffs present on both sides.

In the middle is the game area that comes with a total of 6 reels.

At first, the slot will allow you access to 2-3-4-5-6-7 symbols, on its simple, yet fun cartoon-design.

In addition to the Golden Merlin (wild), and Anchors (scatter), other symbols on Big Fin Bay include Royals (9 to A), Fisherman, plus four varieties of fish.


Big Fin Bay is a good slot title, even though it uses a common theme. The features are great, and so is the payout.

Because of its high volatility, I can only recommend it to more experienced players.
