How to play Big Fin Bay mobile slot

Time to go fishing for the biggest catch of the year as this Big Fin Bay slot may pay out as much as 15,040x your bet, thanks to Free Spins, Wilds and a decent 96.14% RTP.

Set in a small fishing village off the coast of Maine, this New England village has crystal clear water and blue skies that go on forever.

Big Fin Bay mobile slot is an unusual game when you open it up – you might even think it has the same mechanics as a Megaways slot as each reel has 2, 3, 4, 5, 6, and 7 symbols.

Like a Megaways, the rows of the symbols shift from spin to spin. Unlike the Megaways, the reels ALWAYS have 2, 3, 4, 5, 6, and 7 symbols – giving you a total of 5040 ways to win on each spin. It’s different, but still a whole load of fun.

The Big Fin Bay slot has expanded reels and respins

The wild is the big win symbol in the base game, mostly because it will always expand to cover the whole reel and add an extra symbol to the reel.

So if you get the wild on a 2-row reel, it will expand to give you 3 symbols (and slightly more ways to win) and then give you a free re-spin of the reels to catch another win. Each and every time.

It’s exciting to watch, and you can get up to 3 wild reels on any spin. That’s half the Big Fin Bay slot, which is full of wilds and full of respins.

Expands to 117,649 ways to win slot machine

Now it is impossible to get that kind of expansion in the base game because you can only have 2 reels expanded to 7 symbols high, logically.

But in the Big Fin Bay slot free spins, things are a little different. The reels lock and when you get a wild on the reel, the row will expand on that reel for the duration of the free spins.

That means that if you get enough wilds on each of the reels, you could expand all the reels to 7 rows high and get that max win. There are no multipliers, but that makes the top win of 15,040x your bet on this Big Fin Bay online slot all the more impressive.

Fans of Bonanza slot and the Fruit Shop Megaways review will enjoy this light and breezy Big Fin Bay.

Bonus Features

Expanding Wilds and Respins: The golden fish is the wild symbol and will substitute for all other symbols except the scatter. A maximum of 3 reels may contain Wild symbols on the same spin.

When the wild lands it will expand and cover the reel. You'll then get one free re-spin of the reels, and expand the reel by one symbol, up to 7 symbols high.

Mystery Wilds: In the base game up to 3 reels become Wild symbols. No Scatter symbols can appear during this feature.

Reel Height: In the base game the reels have set heights of 2, 3, 4, 5, 6 and 7 symbols, which randomly changes on each spin. The number of bet ways in set as 5,040 ways to win. However, in the bonus game, the reel height of each reel can expand up to 7 symbols each, giving you 1117,649 ways to win.

Scatters and Bonus Games: 3 or more Scatter symbols will trigger the free spins. Each of the scatters will then give you a random number of spins. For example, one can give you 4, the other 6, and the other 2 giving you a total of 12 free spins.

The reel heights in the spin that triggers the bonus game will lock into place - again one with 2 symbols, the other with 3, then 4, then 5, 6 and 7.

When a wild lands on the screen, it will expand to cover the reel, give you a free re-spin of the reels as usual. Except for this time around it will also expand the reel it lands on by one, up to a 12 row high.
