For some fishing is a relaxing past time activity, for some fishing is their whole life. If you’re not so interested in fish, then you might be interested in fishing for some big wins, because that is what we are about to do on Big Fin Bay. The talented team of Thunderkick have come up with another brilliant slot, which introduces us to a whole new world. The fishing theme is not the most popular one, but we still get a couple of slots that use this setting, good examples being Fishin Frenzy, Fishin Reels and Old Fisherman. Are you ready to join the sailors?

Thunderkick tends to get overlooked from time to time. This is a provider that has brought us some gorgeous slots with some massive payouts. Fortunately, Big Fin Bay follows the footsteps of predecessors, being both, good-looking and well-paying. Big Fin Bay is actually very similar to Megaways slots. The game layout has been extended to match those same parameters and also the payline amount has been greatly increased. Big Fin Bay is a 6 reel slot, with row amount ranging from 2 to 7. During the base game, we get 5,040 paylines, while during the bonus game they skyrocket to 117,649. It’s a bold move from Thunderkick, let’s hope it works out.

Gameplay and Payouts

The presentation for Big Fin Bay definitely is a pleasant one. We haven’t seen anything like this in a long time. Big Fin Bay has that old school slot look to it. The coastal line reminds us of the Hellcatraz slot from Relax Gaming. We appear to be somewhere along the shores of the Mediterranean. The music is another interesting element, It creates this dramatic Italian Casa Nostra drama atmosphere, plus the sounds of the water and seagulls add another level of immersion. It’s actually pretty hard to mix the old school with modern in hopes to create something great, but Thunderkick did it, so kudos to them. Big Fin Bay may look like a Megaways slot, but the symbols, unfortunately, don’t tumble.

The symbol game is not that strong, but Big Fin Bay has a couple of nice ones regardless. The most plain surely are the low ones. These are symbols such as 9, 10, J, Q, K and A, styled in a simple colourful fashion. High-value symbols are four fishes that have been put on a display as trophies, but the fisherman, who is also the highest value regular symbol. And might we add, that he is a proper fisherman, with a white beard, a pipe and fisherman's hat, squinting his eye like Popeye. Big Fin Bay Wild symbol is a golden swordfish. This symbol has a big role when it comes to Big Fin Bay bonus features.

Big Fin Bay is a high volatility slot, so we are not looking at peaceful fishing by the pond, it’s more like fishing for king crabs in the stormy seas of Alaska. In all honesty, though, it’s not that bad, as the hit rate for wins is quite decent. The default RTP of the slot is 96.14%. Thunderkick is one of those providers that don’t shy away from big payouts, and we are glad to say, that Big Fin Bay has received that treatment also. The max win is 15,040x, which is really good for a day at the sea. Bet range is wide enough, being 0.10 – 100.

Bonus Features

The swordfish Wild is the main catch of Big Fin Bay. If a Wild symbol is included in a winning combination, it will expand, covering the whole reel with Wild symbols. Additionally, during the base game, a Mystery Wild feature can randomly activate. This will turn up to 3 reels into full wild versions. To even the odds, no scatters can appear during this bonus spin.

Big Fin Bay Bonus Free Spins are triggered by 3 or more scatters. Each scatter can bring up to 6 Free Spins, so you can get as much as 36 Free Spins. Like before, Wild symbols expand, but now they also trigger a re-spin. During this re-spin Wild symbol increases the number of symbols on its reel by one, which creates more paylines. If you expand the reel with up to 7 symbols, then additional 3 Free Spins are granted. So keep an eye out for those Wilds, because that’s where the money is made.

Big Fin Bay slot is a really pleasant release from Thunderkick. Often the presentation for fishing themed slots is rather boring, so it is great to see Big Fin Bay breaking this habit. We have to wonder, how much more appealing this game could be if it came with the actual Megaways engine, instead of just mimicking the model. Wild symbols are the main priority, so in a way, we are trying to catch them the same way fishermen try to catch fish. No matter if you do or don’t like fishing, Big Fin Bay is a great piece to play for all.
