Bonus Features

This game offers players additional bonus rounds, where you can fish for free spins. You also stand a chance of entering a mystery jackpot.

Game Symbols

During your deep-sea adventure, you’ll come across 9 special symbols and card values. The scatter is a pair of dolphins, awarding a bonus round when you land 3 of a kind or more. At the same time, Neptune himself assumes the role of the wild icon.

The best symbol in the base game is the mermaid, rewarding a multiplier of 1,000 for 5 matching icons. Other valuable characters take shape as a treasure chest, an octopus, a blue tang, and a clownfish. 

Additionally, you’ll see an oyster, a starfish, and the usual low paying card values between 10 and ace. 

Bonus Rounds & Free Spins

This aquatic slot also has a bonus round with massive payouts and two unique super wilds. What’s more, players can win more spins to prolong their stay in the free game. The prizes all depend on which super wild you choose.

You’ll have the option to pick between the two characters before you start. If you trigger the super Neptune symbol, it awards 15 free spins. Every time you land on this icon, it changes the entire reel into a big wild. This gives you an additional free spin, allowing you to continue the round, maxing out at 300 spins.

On the other hand, if you choose the super mermaid wild, you’ll get 10 free spins. Every time the symbol turns up, it’s fixed in place, remaining there for the rest of the round. This character also rewards a free game but tops out at 100 spins.
