About this Slot
Mutation Lab is a horror, alchemy and sci-fi themed slot from Tilt Room Games with an RTP of 95.1%, high volatility and a maximum win of 25,000x. The game plays across 4 reels and 4 rows, with 256 ways expanding to a maximum of 4096 ways.
Split canisters crack into two to four copies of a symbol, stretching the reels taller and expanding the grid towards the 4096 ways maximum. Strain mutates a symbol by converting up to three matching symbols directly above or below it on the board. Multiplier frames land randomly on the grid, doubling values from ×2 up to ×512. When symbols form winning chains, multipliers on covered cells are added to the total. Winning symbols then dissolve, triggering respins on the same board while boosted cells remain active.
Three scatters trigger the Bonus feature and award 5 free spins. Four or more scatters trigger the Super feature and award 7 free spins. During free spins, the grid carries over between each spin. The Bonus feature drops one to four multiplier frames per spin, while the Super feature drops two to five multiplier frames per spin and triggers Strain more frequently. Three or more scatters landing during the feature retrigger an additional three spins.
A Buy Feature option grants direct access to the bonus round or increases the trigger chances for scatter combinations.
