About this Slot
Lab Breach by Sunnie Gaming is an alchemy and sci-fi themed slot with 7 reels and 7 rows using cluster pays mechanics. The game has an RTP of 96.7%, high volatility and a maximum win of 20,000x.
Winning clusters leave patches on cleared cells, with each patch carrying a single multiplier across its entire footprint. Normal patches grow by cluster size after each win, and their multipliers increase as they expand. Patches merge when their footprints overlap, creating a shared multiplier value from the combined patches.
Mutated Patches are a special variant that double in size as they grow, with no growth cap applied. This removes the standard multiplier ceiling and allows Mutated Patches to reach a maximum of 2,500x.
Three Containment Breach Alarm scatter symbols trigger the free spins bonus round. Landing exactly three of these symbols awards five extra spins. Active bonus patches remain in play throughout the free spins, and bonus mode persists if the bonus retriggered with more scatter symbols.
Mutagen Vial symbols mutate any unmutated patches containing exactly three cells, converting them into Mutated Patches. When no eligible patches exist, Mutagen Vial acts as a wild symbol instead.
The game offers three feature buy options that guarantee access to the bonus round without requiring a natural trigger from scatter symbols.
