Expanding Sirens
Sirens are wild symbols that expand upwards to the top of the grid when they would form part of a win after expanding. They carry multipliers up to 200x, applied to any win they pass through; multipliers on the same winline are added before being multiplied by the payouts. Only Yellow Sirens appear in the base game, and they disappear after each spin.
The Sirens' Call Bonus
Landing 3 FS symbols in the base game awards 10 Sirens' Call free spins, with greater odds of Sirens appearing throughout. Pink Sirens may also appear; they remain where they expanded, nudge off one row at a time until removed, and carry 2x to 200x multipliers.
The feature can be retriggered: 2 FS symbols award 2 extra spins, and 3 FS symbols award 3 extra spins.
Down Below Bonus
Landing 4 FS symbols in the base game triggers the Down Below bonus with 10 free spins. Expanding Wild Divers always fully expand to cover an entire Diver Reel; each gets 3 full Oxygen Charges and vanishes when its Oxygen reaches 0. Divers may move to adjacent reels at the start of every spin, consuming 1 Charge and possibly changing their multiplier value.
Divers carry multipliers up to 200x applied to every win they pass through; multipliers from multiple Divers in the same win are aggregated and applied to all corresponding wins, and at most 3 Divers may appear at once. During the feature, 2 FS symbols award 2 additional spins and 3 FS symbols award 4 additional spins.
Bonus Buy
The Bonus Buy feature lets you dive rapidly into one of the two bonus features.
FeatureSpins
FeatureSpins lets you activate one of the game's special features by increasing your bet size. BonusHunt FeatureSpins gives an increased chance of winning the bonus, and Siren FeatureSpins guarantees each spin has at least 2 Siren symbols land somewhere on the reels.
