About this Slot
Slime Lab is an alchemy and sci-fi themed slot with high volatility, an RTP of 96.5%, and a maximum win of 10,000x. The game features six reels, five rows and 15,625 ways to win.
Cascading reels trigger after each win, removing winning symbols and dropping new ones into empty spaces. Matching groups upgrade by one tier during cascades, with two tiers gained during an Overreaction.
Catalyst Vial identifies the largest symbol group it touches and upgrades that group by one tier. Specimen Tube tracks the total number of upgrades across all cascades and releases a Mega Goo wild when each mark is reached.
Mega Goo wilds substitute for any symbol and remain in place through subsequent cascades. Mega Goo anchors winning chains that begin from the leftmost reel.
Reactor Core scatters trigger Free Spins only on their initial reveal. Three Reactor Cores award 8 Free Spins, four Cores award 10 Free Spins, and five Cores award 12 Free Spins. Additional Reactor Cores that land during Free Spins retrigger the round and add more spins. During Free Spins, the upgrade ladder extends to create Mega Goo wilds, which remain sticky across the additional spins earned through retriggers.
