How it plays

A 6×5 graveyard board on 50 lines, built on one idea: the Grave Grab. Wilds land as tombstones, each one cracks open, and a zombie hand rises up its reel grabbing every symbol on the way. Each grab adds that symbol’s multiplier to the hand’s tag, up to 8x, so a single wild can carry a whole spin. The three bonuses push that same mechanic rather than replacing it: Restless Night makes wilds land far more often, Soul Keepers hangs lanterns that hold every hand’s multiplier for the rest of the round, and Open Graves leaves the graves open so they grab on every spin. Double Chance and a mystery buy sit alongside them.

Across the 47 titles the max win runs from 1,000x to 100,000x and RTP from 94.99% to 96.70%. Grave Mistake sits at 25,000x and 96.70%, with high volatility. It also runs the joint-highest RTP across both studios.
