Theme and Graphics
Big Fin Bay is set in a beautiful, coastal location. The houses lining the reels have a distinctly Mediterranean look about them, so the game takes you on an exotic adventure in a beautiful locale.
The soundtrack of the slot is also quite nice, fitting the nautical theme with a little bit of quirk thrown in like we’re used to seeing from Thunderkick slots. Games like Pink Elephants 2, Beat the Beast Kraken’s Lair and Crystal Quest all have a fantasy element to them – so, while the theme for Big Fin Bay is a little more normal, the soundtrack gives the slot that little bit of the edge.
Big Fin Bay RTP and Variance
The RTP (return to player) of Big Fin Bay is 96.14%. This is about average for new releases today, since most slots have RTPs of about 96% to 95.6%.
This is also a highly volatile slot. So, you can expect larger payouts than are available in other slots but they don’t come around all that often. The top win in this game is worth over 15,000x, which you don’t really see all that often in Thunderkick games.
How to Win
There are 5040 ways to win in Big Fin Bay. It looks a bit like a Megaways game, with all reels featuring different sized symbols on every spin – but, you always end up with a total of 5040 winning ways.
Wilds and Mystery Wilds
The wild symbol in this slot is the sword fish. Whenever it appears on the reels, it will expand to fill up the entire reel and give players a better shot at potentially landing a payout.
Free Spins and Bonuses
When three or more scatters land on the reels, you’ll trigger the free spins bonus. To determine the number of free spins you’ll receive, each symbol that activated the bonus will reveal a number. The maximum number of initial free spins you can receive is 36.
During this round, wilds landing on reels will grant a respin and expand the reels they land on by causing more symbols to appear on it. If a reel ends up with 7 symbols, you’ll get an extra 3 free spins. Should you manage to expand all of the reels fully, you’ll have 117,649 ways to win.
Big Fin Bay Slot Review
Big Fin Bay is a high variance slot, and it really plays like it. Wins don’t really come around all that often during the base game, so you do have to wait a little while before you can bag any of the wins on offer.
Usually, we say that a game should have an additional feature to break up the monotony – but Big Fin Bay actually does have the expanding wilds and mystery wilds. They just don’t appear often enough to keep things very interesting in the base game.
However, once you’re in the free spins round, things get a lot more fun. You have the expanding reels feature available which helps to make wins appear more frequently. So, it’s a step up from the base game.
The theme is another good thing about this game. Big Fin Bay is just a very well-designed slot with detailed graphics and a unique setting – but, we’ve come to expect this from Thunderkick slots.
If you’re looking for something from this developer with a little more going on, then we’d recommend something like Esqueleto Explosivo. Although the top win on offer is significantly lower than in Big Fin Bay, it’s a lower variance slot where something interesting is happening on almost every spin.
