About The Game

The theme of this slot is a mix of fantasy and underwater, as our mermaid protagonist takes the lead role here.

Animations are smooth and you like, flowing like water itself, whilst reels are made, symbols detailed and the backdrop is visually pleasing as well. The ocean floor is the setting, with bubbles, coral and seaweed decorating the deep blue. Bubbles are multicoloured and come in purples, pinks and greens, adding some variety and vibrancy to a game that could have easily been quite dark, what with the ocean bed setting.

As for the symbols, they all have a sea theme. Playing card symbols of between A and 10 have undersea plantations wrapping themselves around them. These act as the lower paying symbols in Siren’s Kingdom and as you’d expect, their value is represented by their value as a card, with A being the best of them.

As for the higher payers, seashells, clam shells and starfish come into play. All made of a golden sandy colour, the best of them will pay up to 13.33 times your stake should you land 5 of them on the same pay line. As for the wild, this is represented by the red-haired siren, the mermaid.

Whenever a mermaid wild lands, it fills the entire row and she will also substitute for any other symbols apart from the scatter. Landing multiple sirens on one spin will lead to a rewarding multiple wilds. The scatter symbol is the integral to the main feature here and is represented by an octopus holding a pearl. This will reward free spins should you land at least 3 of them, with up to 36 free spins available if you land 5.
