About this Slot
CRABS LABS is a sci-fi themed slot by Crabz Labz with an RTP of 96.5%, high volatility and a maximum win of 48,000x. The game uses a 5x5 grid with Cluster Pays, awarding wins when eight or more matching symbols land anywhere on the reels.
Cascading Reels remove winning symbols and drop new ones into place. Each cascade win creates exactly one new Wild and increases a shared multiplier that starts at 1x and doubles after each cascade. Wilds disappear along with winning symbols after the payout is calculated.
Mythic Specimen transforms groups of symbols into a single symbol or a Wild. This feature can also turn positions into Scatters, creating additional winning opportunities.
Three Scatters award eight free spins, four Scatters award ten free spins, and five Scatters award fifteen free spins. Additional Scatters landing during the trigger improve the bonus tier.
During free spins, Toxic Reactions resets the multiplier to 1x on each spin. Chain Reaction carries the multiplier between free spins in succession. Critical Mass carries the multiplier across spins and guarantees one Wild lands on each spin.
Bonus Boost increases the chance of landing Scatters at a higher cost than standard play. Mythic mode can trigger a normal spin or one of three bonus tiers. Direct purchases skip to free spins.
Reactor Release reveals the outcome after a preview board displays. Green pulses release Wilds, purple releases Mythic Specimen, and cyan releases Scatters. Wild Burst adds one to three Wilds with a 6% chance and can appear after any winning cascade.
