Laboratory of Madness
The ZapLab online slot is the brainchild of ELK Studios, a slot provider known for unique themes and innovative mechanics.
The action in this game unfolds in Dr Mayhem’s lab, which is full of strange science experiments and glowing lights. A collection of monster characters serve as symbols in the ZapLab slot machine, each with its own unique look and personality.
Unleash the Monster Features
This new slot has high volatility and an RTP of 94%. You can place bets of between 0.20 and 100 coins.
The ZapLab online slot uses a cluster pay mechanic, with five or more connected symbols triggering wins. Winning symbols will disappear, with new symbols dropping down to fill the gaps.
The Monster Meter drives the action. Scoring wins will fill the meter and, once full, it unlocks special features. Monster Reload provides symbol redrops, Wild Flip converts random symbols to wilds, Monster Chunks creates 2x2 symbols, Monstrous expands symbols up to 5x5, and Zapocalypse drops Dr Mayhem symbols for Zappy to zap.
Zappy himself acts as a roaming wild as you play the ZapLab slot online, jumping to new positions after wins while leaving wilds behind. He attacks Dr Mayhem symbols on sight, increasing his multiplier and potentially expanding up to 4x4 size.
