Developer Queen of Sirens is a video slot by Evoplay with a 3x3 reel layout, high volatility, and an RTP of 95.97%. The game includes a bet range from 1 to 75 and is built around an underwater theme with mermaid imagery, a golden seashell, and ocean symbols. Players looking to try the Queen of Sirens demo version can play for free and practice before playing for real money.
The slot features the Sticky Coin, which guarantees a reward during the Bonus game, while the Octopus can duplicate rewards across the reels. During the Bonus or Ultra Bonus game, Luck of Aurora places 1 to 9 water splashes on random cells, each carrying an x2 multiplier. The Mystical Chest adds another feature layer, while the Mystic Jackpot symbol can trigger one of three fixed jackpots.
According to the game information, the Grand Jackpot is awarded for filling the entire field during the Bonus game. Queen of Sirens also combines bonus buy and jackpot mechanics, making it a slot focused on feature-driven gameplay rather than a fixed payline structure.
