About this Slot
Lab Leak is a pandemic-themed slot from Twist Gaming with an RTP of 96%, high volatility and a maximum win of 10,000x. The game plays on a 7x7 grid using a Cluster Pays system.
Cascading wins remove winning symbols, allowing new symbols to fall and create additional winning combinations. Virus Spread is triggered when a virus wild appears in a cluster win, expanding to adjacent cells via hold and spin mechanics. During expansion, prize symbols, virus symbols and multipliers land on the grid. The feature continues until no new prizes appear.
Free Spins are triggered by four or more bonus symbols landing on the grid. Four bonus symbols award 10 free spins, with each additional bonus symbol adding 2 free spins. Virus Spread remains active during the Free Spins round. Retriggers occur when two or more bonus symbols land during Free Spins, awarding the same number of extra spins as the initial trigger.
Four bonus buy options are available. FS Trigger Boost costs 2.5x your bet. Virus Boost costs 5x your bet. Virus Spread Boost costs 30x your bet. Free Spins Bonus costs 300x your bet.
