Big Fin Bay Slot Review

Thunderkick transports players to an idyllic fishing setting for Big Fin Bay. Although the slot shares a number of uncanny similarities with other titles, the provider has managed to create a unique experience that stands on its own.

The theme is very similar to other fishing themed video slots we’ve already seen. It maintains the old school vibe in both background and symbol designs, with very little in terms of animation going on. You’ll either love it bits or absolutely hate it.

But what lies under this video slot’s hood? Is this haul worth the effort or are you better off chucking it into the depths of the sea? Read our full review to find out.

Big Fin Bay Bonus Features

For Big Fin Bay, Thunderkick managed to build a set of video slot features that work in tandem to create a holistic, tiered experience. It’s a system that works brilliantly, layering one bonus on top of another to create a real sense of progression within the game.


Landing in the shape of a Marlin, the Wild symbol steps in to fill in any gaps needed to complete a winning combination. Additionally, the Marlin Wild will expand to cover its respective reels whenever it forms part of a winning set.

Big Fin Bay also offers the Mystery Wild feature. Randomly triggered during the main game, this mechanic turns up to three selected reels into full wilds for the duration of a given spin.

Scatter Symbol

Players will need to collect a minimum of 3 Scatter symbols to access the game’s bonus segment. Each reel can award players with up to 6 free spins, with a grand total of 36 free spins awarded to those lucky enough to land a Scatter symbol on every individual reel.

Free Spins / Respins

The main difference between the main game and free spins, is the fact that whenever a Wild symbol forms part of a winning set, apart from expanding to cover its respective reel, it also activates a re-spin.

During the re-spin, an additional Wild symbol is added to the wild reel, expanding the number of rows and betways. These expanded reels remain for the duration of free spins, reaching a maximum limit of 7 rows that offers a combined total of 117,649 ways to win. Every expansion also brings with it an additional 3 free spins.

Big Fin Bay Jackpot

Although Big Fin Bay sports a decent variety of features, it sadly does not include a jackpot prize.

RTP & Volatility

Big Fin Bay takes its volatility setting all the way up at an incredibly high level, while setting its return to player rate at 96.14%. Combined with the max win amount, the math model allows for great potential and some great wins. Then again, as delightful as the high volatility setting might be for hardcore players, it might also deter casual players who are looking for a more straightforward time on the reels.

Where to Play Big Fin Bay

You can enjoy the best that Thunderkick has to offer at a selection of licensed casinos. If you’re looking for a definite suggestion, we recommend playing Big Fin Bay at Pokerstars, the best place to play the provider’s offerings.

Big Fin Bay on Mobile

Want to take your fishing slot on the go? You’ll be happy to hear that Big Fin Bay is fully compatible with mobile devices, transferring the action to the small screen without compromising on any aspects of the desktop experience.
