About this Slot
Infection is a horror-themed zombie sci-fi slot from Knockout Labs with an RTP of 96.7%, high volatility and a maximum win of 2,500x. Wins form with five or more matching symbols connected horizontally or vertically in a cluster pays format.
When winning symbols clear, replacements tumble down to create further winning opportunities on the same spin. Each winning connection that does not include a wild generates one Infection Wild worth 1x, which moves into an open position on the grid.
Infection Wilds that are linked together merge and grow, accumulating multiplier value up to 2,500x. Each participating wild gains +1x for every connection it is part of, allowing multipliers to rise rapidly through cascading wins.
Three scatters award three free spins, four scatters award five free spins, and five scatters award eight free spins. Ten or more scatters award between ten and twenty free spins. Infection Wilds remain sticky throughout the free spins round.
Three or more scatters landing during free spins retrigger the feature. The H1 premium connection places an L1-L4 3×3 square after tumbles resolve. The H2 premium connection doubles all pre-existing wilds up to 2,500x. The H3 premium connection adds one extra 1x wild when eligible.
The Hazmat symbol places a random 3×3 square after tumbles resolve. The Virus symbol doubles all pre-existing wilds up to 2,500x. The Toxic Waste symbol adds one extra 1x wild when eligible.
