Can you hear the siren’s song? Siren’s Spell is an online slot game designed and released by Habanero that takes you deep underwater to a mysterious kingdom. Visually, this is a modern release with original symbols in vivid colors, blue reels, and decorated frames. The background image depicts the underwater kingdom with ancient buildings.

Siren’s Spell is equipped with 5 reels and has 25 paylines. You should expect eight regular symbols: four shells in different shapes and colors, a sea turtle, a shark, a seahorse, and a jellyfish. Naturally, the siren is the slot’s wild symbol that replaces all regular symbols to help you form winning combinations. Any siren that will land partially on any reel will nudge down or up to cover that reel.

The clam with a pearl acts as a Scatter symbol. Players need three clams anywhere on the first, third, and fifth reels to start 15 Free Spins. During this round, landing in winning combinations with turtles, sharks, and seahorses contributes to the corresponding counter. Once you fill one of the counters, you will get 15 more free spins. In addition, every symbol is upgraded to the following higher-paying symbol. Lastly, this game has a super bet that boosts your chances of triggering free spins and a bonus buy feature that lets you purchase free spins and use them right away.
