Many providers have slots about mermaids, because players like them. Those games mostly have classic mechanics and easygoing gameplay. This one is classical only partially due to 3x3 board. But nudging and sticky wilds do not sound like something classical.
The slot title says it all. 3 Mermaids are main heroes and main symbols. They act as wild, and each has unique feature. You’ll be catching them pretty often, and if you catch 2 of them at the same time – a big win is guaranteed.

3 Mermaids is rather simple 3x3 slot, that might seem quite boring, but in fact is the opposite. When it comes to overall appeal and slot's environment, it excels. There is no sufficient risk to your balance, since it does have medium volatility and an alright max win potential, that exceeds 1300x. There are no free spins or bonus rounds, however, there is a re-spin feature, whenever you land a mermaid. In order to win big, you need to aim for landing 3 mermaids, hence the name of the slot.
