ZapLab

ZapLab from ELK Studios has an RTP of 94% with high volatility and a maximum win of 10,000x.

The Monster Meter fills by collecting winning pay symbols. When the meter reaches full, it awards either a random Monster modifier or a feature symbol. Modifiers are held and activated when no further wins remain on the current spin.

Five meter fills during a single round trigger Shockwaves, which activate all five modifiers in a fixed sequence: Monster Reload, Wild Flip, Monster Chunks, Monstrous, and Zapocalypse. If the meter fills again during Shockwaves, the sequence repeats.

Feature symbols land from regular play or from the Monster Meter and act as wilds on the grid. When a feature symbol lands, its special ability activates.

Zappy wild appears randomly and jumps across the grid after wins, leaving wild symbols behind as it moves. When Zappy zaps Dr Mayhem, its multiplier increases. Zapping Dr Mayhem also boosts the Monster Meter. On its final zap, Zappy may expand to a 2x2, 3x3, or 4x4 wild formation.

X-iter bonus modes provide special gameplay formats for alternative ways to engage with the game's mechanics.
