Play Mutagenes Slot by Peter & Sons for Free

Mutagenes by Peter & Sons takes you inside a high-variance research laboratory on a 6x4 grid with 4,096 ways to win. Avalanche cascades remove winning symbols and drop in new ones, while a rising win multiplier stays active throughout each chain of wins. Expanding wilds stretch to cover full reels, and two random in-game features — Infection and Mutation — can transform low-value symbols into higher rewarding ones at any point. A free spins round keeps the multiplier running without resetting. Play it free at Spree with Gold Coins, no purchase needed.
