Our Verdict:

Siren's Kingdom is a really fun slot game with a lot of good things to offer.  The game is graphically excellent, and there has been a real eye for detail in the design. The game is set at the bottom of the ocean, and the reels sit against a background of underwater plant life and creatures. The transparent reels also help bring the scene to life, especially with the various sea creatures which have been used as symbols.  One of those symbols is the starfish, however, the real star attraction on Siren's Kingdom is the two bonus features, where 36 free spins can payout nice returns.

Wild Symbol:

On Siren's Kingdom there is the wild symbol which in this case is the red-haired Siren the mermaid. This symbol is a special symbol as she can complete combinations involving must other symbols on the game.  She will complete combinations involving the lower value playing card symbols of A, K, Q, J and 10.  She also completes combinations involving the higher value sea creature symbols including starfish, shells, and pearls.   The wild will not substitute for the scatter symbol.

Expanding Wild:

The wild Siren symbol on Siren's Kingdom is not a traditional wild, despite behaving like one and substituting to complete combinations. This wild symbol can not land on every position on the reels, instead, it is only possible to land her on the top position the reels.  When she lands, she will also expand and fill the entire reel, allowing for more opportunity for her to complete combinations. Players can also land multiple wilds at the same time, all of which will expand and can create combinations.

Free Spins:

The main bonus feature on Siren's Kingdom is the free spins bonus.  To trigger the bonus three, four or five of the scatter Octopus holding a pearl symbol must land in a single spin. If triggered by three it will award 14 spins, four triggering symbols will award 25 spins and a full house of five symbols triggering the bonus will award 36 free spins.  During the spins, the Wild Siren symbol will not expand when she lands, however it is a sticky wild.  What that means is the wild symbol will freeze in place and expand to adjacent reels. After a few spins, it will disappear.  You can also land multiple sticky Siren Wilds leading to  real potential for great wins.
