MUTAGENESIS MAYHEM

About this Slot

MUTAGENESIS MAYHEM is a horror and sci-fi themed slot from Mutagen Labs with an RTP of 96%, high volatility and a maximum win of 10,000x. The game uses a 5x5 grid with cluster pays, where matching symbols score when they connect orthogonally anywhere on the board. The Wild Symbol acts as a regular substitute, while the Scatter Symbol lands on the initial drop to trigger bonus rounds. Cascading Reels apply after each winning cluster disappears, causing symbols to fall and new ones to drop in from above. Sticky Wilds remain in place across multiple cascades, and a Multiplier increases with each consecutive winning cascade. Mutation Spread fires before symbols are scored, with green Mutagen orbs transforming nearby lab tags into medium symbols, then premium symbols, then Unstable Wilds. Each transformation step is random within its tier, so the same orb reshapes the board differently on each spin. Unstable Wilds carry multipliers affecting cluster payouts. Natural wilds start at x2, x3 or x5, while mutation-promoted wilds begin lower and can climb to x128 when touched by Mutation Spread, which doubles them instead of transforming them. Chain Reaction Multiplier increases by one after each fresh cascade that pays, reaching up to 20 consecutive steps before resetting on the next spin. Mutation Overload is a rare random event triggering before Mutation Spread begins, rewriting a large section of the grid with premium symbols and wilds, then injecting 1 to 3 fresh wilds. Normal mutation and chain rules apply afterwards. Landing 3 or 4 biohazard scatters on the initial dropped board triggers free spins, each bonus starting with one guaranteed mutagen on the grid. Sticky Specimens persist between spins in Containment Breach, while the chain multiplier also persists in Hot Zone. Four bonus buy options accelerate access to the feature: LAB SURGE at 1.25x bet, SUPER SURGE at 3x bet, CONTAINMENT BREACH at 100x bet, and HOT ZONE at 250x bet.
