About this Slot
Grimoire of the Deep is an action and adventure fantasy slot from 4phantom with an RTP of 96.02%, high volatility and a maximum win of 25,000x.
Cluster wins form when five or more matching symbols connect horizontally or vertically. Winning symbols cascade down the reel set, with new symbols falling in to create additional wins from a single spin. Multiplier positions on the board increase on repeat wins during cascades, starting at 2x and climbing up to 1024x. These base game multipliers reset after each spin and cascade sequence ends.
Three or more Scatters trigger Free Spins. Three Scatters award ten spins, four Scatters award twelve spins, five Scatters award fifteen spins, six Scatters award twenty spins, and seven Scatters award thirty spins. Multipliers earned during the Free Spins round persist across the entire feature. Scatters landing during Free Spins retrigger the feature and add more spins to your total.
Four bonus buy options let you enter Free Spins directly. The ENHANCED option costs 3x your bet and awards ten to thirty spins. POWER UP costs 64x your bet and follows the same multiplier and retrigger rules as the base Free Spins feature. Bonus costs 100x your bet, while Super Bonus costs 500x your bet. Super Bonus starts all multiplier positions with 2x multipliers and awards three to seven Scatters.
