Let yourself be seduced by sea

You’ll travel to a fantasy, underwater marine world and journey through the deep blue sea, meeting intriguing characters as you go.


The moment you begin your game you’ll feel immersed in the undersea setting, backed by a soundtrack of bubbles, rushing water and surrounded by vibrant blue and vivid colourful scenery.


Activate each payline by wagering more coins. The more coins you bet per spin, the more paylines you open up. Playing with the maximum bet will give you the chance to win the game's jackpot – a treasure chest of 37,500 coins.


A beautiful mermaid acts as the Scatter symbol and if you land three or more of the fishy femme fatales you’ll be awarded with 10 Free Spins.


King Neptune is the game's Wild symbol, replacing all other symbols on the reels while also acting as a Multiplier. If he appears as part of your winning combination, the value of your win increases threefold.


If you land three or more treasure chest symbols you’ll activate the bonus game where you can choose from a number of sunken trunks to add bonus win values.


Players can bet for as little as 0.01 per spin, making this a perfect game for first timers but with the flexibility for more experienced players enjoy themselves too.


Let yourself be seduced by sea – check out Mermaid Millions now.
