Queen of Sirens

Queen of Sirens is a video slot from Evoplay with an underwater theme where you encounter a siren with an azure blue tail and shimmering shells among corals and dark underwater ruins. The game features a compact playing field of 3×3 positions without traditional paylines; instead, Bonus or Ultra Bonus rounds are activated when enough Bonus symbols appear on the central row, often in combination with the Octopus symbol. Sticky Coin symbols can land in the main game and "stick" until a bonus round starts, carrying a high random value with them.

In both the Bonus Game and Ultra Bonus Game, each spin brings new Bonus symbols that remain in place and reset the number of spins to three when a new Bonus symbol falls; the game continues until spins run out or the entire playing field is filled with Bonus symbols. Ultra Bonus differs by starting with three or more symbols on the central row and the Luck of Aurora feature always activating at the beginning and occurring more frequently during the round. Luck of Aurora shoots 1 to 9 water splashes on random cells, leaving x2 multipliers that can stack; if a water splash hits a cell that already has a multiplier, the value increases by +1.

Mystic Chest appears during bonus rounds and contains secret rewards, while Mystic Jackpot symbols grant access to one of three fixed jackpots – Mini, Minor, or Major. If the playing field is completely filled with Bonus symbols during a Bonus round, you are rewarded with the Grand Jackpot, which is the highest of the fixed jackpots. Bonus Buy is available for players who want to skip the main game and directly purchase access to one of the bonus rounds.
