About this Slot
SLIME OUTBREAK is a horror and sci-fi themed slot by Ryvex games with an RTP of 96%, high volatility and a maximum win of 25,000x. The game uses 6 reels, 5 rows and Cluster Pays mechanics, where matching symbols connect horizontally or vertically to form winning combinations.
Symbols cascade when matched, with slimes splitting and multiplying during the cascade sequence. Reel modifiers carry across spins while cascades are active, allowing effects to build across multiple drops.
The Ooze feature applies a global multiplier that starts at 1x and increases by one per cascade, never resetting until the round ends. A big slime drops on the first spin of this feature.
Infection is a base game feature where winning cells start at 2x and increase by one with each additional win. Infected cells never reset during the round, allowing multipliers to accumulate.
The Breeding bonus awards 10 free spins with slimes that persist between spins. Small slimes double when winning, up to a maximum of 16x.
The Mother bonus costs 500x bet and awards 10 free spins. The mother slime starts at 4x multiplier, while small slimes double up to 32x.
Slime Spin is a 30x bet buy option where 3x3 slime drops land each spin. Large slimes split when helping form winning combinations.
Toxic Spin guarantees a feature every spin, landing either a small slime, Slime Rain or Toxic Splash.
Boost mode activates on demand and triples the frequency of Free Spin triggers.
