About this Slot
Marine Mania is a fantasy-themed slot from High Rollers with an RTP of 96%, medium volatility and a maximum win of 5,000x.
The game features cascading reels, where winning combinations remove symbols and allow new ones to drop into place. Wins can occur anywhere on the reels, and scatter symbols pay regardless of position. Multiplier symbols accumulate during play to boost payouts.
Landing three FS Scatter symbols triggers Rising Pearls, a bonus round awarding ten free plays. During Rising Pearls, multiplier values build within each spin and reset when the next spin begins. Free plays within this round can retrigger to add additional rounds.
Landing four or more FS Scatter symbols instead triggers Tidal Rush, which also awards ten free plays. In Tidal Rush, multiplier symbols carry their value across all ten plays rather than resetting between spins. Free plays can retrigger to extend the round.
Bonus Hunt is a toggle option that can be switched on or off at any time, costing 2x the base play amount. When active, it increases the frequency of FS Scatter symbols by 3x.
Pearl Tide costs 50x the base play amount. It guarantees a minimum of three multiplier symbols on each spin and blocks FS Scatter symbols from appearing. The accumulated prize is multiplied by the total multiplier value achieved.
Rising Pearls is also available as a direct buy option for 100x the base play amount, awarding ten free plays with multipliers that build and reset within each spin.
Tidal Rush can be purchased directly for 200x the base play amount, providing ten free plays with multipliers that persist across all spins.
