About this Slot
MUTAGENESIS MAYHEM is a horror and sci-fi themed slot with an RTP of 96%, high volatility and a maximum win of 10,000x.
The game uses cluster pays and cascading reels, where winning symbols fall away to allow new ones to drop into place. Each cascade during a single spin increases the Chain Reaction Multiplier by one, up to a maximum of 20, before resetting on the next spin.
Green orbs trigger Mutation Spread, transforming adjacent symbols upward into Unstable Wilds. These wilds carry multipliers of x2, x3 or x5 naturally, with potential to reach x128. When Mutation Spread affects existing Unstable Wilds, it doubles their multipliers instead of replacing them.
Mutation Overload is a rare trigger that rewrites a section of the grid with premium symbols and 1 to 3 additional wilds, creating extra winning opportunities.
Landing three or four scatters activates free spins and grants one guaranteed mutagen to start. During free spins triggered via CONTAINMENT BREACH, sticky wilds persist between spins. Free spins triggered via HOT ZONE retain the chain multiplier between spins, allowing it to build beyond a single spin's cap.
Four bonus buy options are available: LAB SURGE at 1.25x bet, SUPER SURGE at 3x bet, CONTAINMENT BREACH at 100x bet, and HOT ZONE at 250x bet.
