Siren’s Kingdom bonus, free spins & jackpot

This inviting view of under the sea is enhanced by the atmospheric music and relaxed atmosphere, created by the waters around a coral reef. The symbols are beautifully rendered and a pleasure to play. But as relaxing as it is, make no mistake, playing Siren’s Kingdom slot is exciting and entertaining. The wild, as expected, substitutes for all the other symbols bar the scatter. If it appears on any of the top reels, it will expand to cover the reel, making for some interesting winning combos. The sticky wild is what you have to watch for in the free spins to help you create some interesting payouts.

The golden octopus scatter is what you want swimming into view. Three of them will award 14 free spins, four will give you 25 free spins, and find five of the tentacled wonders of the deep and you get 36 extra spins. Siren’s Kingdom introduces you to mermaid royalty with the siren queen becoming the wild in the bonus feature. When the purple-haired siren glides into view, she can expand in two different directions and remain on the reels for the second spin. Her presence contributes to some potentially big wins, so behave yourself as a guest in her world, and maybe she will put in more than one appearance.
