The beautiful Siren would love you to join her for this underwater adventure slot game Siren's Kingdom.  Set on the floor of the ocean, Siren the red-haired mermaid wants to show you around and take you on a journey towards big prizes.  Siren's Kingdom comes with five-reels and three rows, and the game can be played on mobile, tablet or desktop computers.  There are thirty paylines on the slot, which are fixed in place, and give a minimum bet of at least 30p, with a top bet of £500 also available. On the slot, there are two wonderful bonus features, a free spins feature with sticky wilds and the expanding wilds bonus, which can help you win the top prize of 4000x your stake.

Our Verdict:

Siren's Kingdom is a slot creation of NYX, in collaboration with Iron Dog Studios.   As NYX are involved, the design and graphics of the game you would expect to be on the money, and they certainly are.  Set beneath the waves, at the bottom of the sea, the game's reels are transparent and sit on a seabed backdrop with ocean life and creatures making up the scene.  There are also some pretty cool animations during the game, which work nicely alongside the nautical style sound effects. However, the most important ingredient to any slot is the gameplay, and on Siren's Kingdom you will get a fast-paced slot, with two interesting, but potentially rewarding special additions.

Wild Symbol:

Like a lot of slot games, the wild symbol on Siren's Kingdom is the main character herself, the red-haired mermaid Siren.  The Siren Wild is one of two bonus symbols on the game, and she will prove herself very value as you play the game.  As a wild symbol, Siren can help complete combinations by substituting for missing symbols in that combination when she lands in place of the missing symbol. She will complete the combinations involving all the standard symbols including the playing card symbols of A, K, Q, J and 10, as well as the sea creature symbols including pearls and starfish.  She won't complete combinations with the scatter symbol.

Expanding Wild:

The Siren Wild is also an important symbol as she is an expanding wild symbol.  This means that the Siren symbol can only land on the positions at the top of the reels, but when she lands will expand to fill the entire reel.

Free Spins:

The Siren's Kingdom bonus feature is the free spins bonus.  This feature is triggered when a player lands three, four or five of the scatter octopus symbols in a single spin.  This will reward 14, 25 or 36 free spins, depending on the number of triggering octopus scatters.  During the free spins there is no expanding wild feature, however, the Siren Wild symbol will become sticky.  This means when she lands she will freeze in place.  Although she is not an expanding to fill the entire reel, she will expand to the adjacent reels when she lands.
