ZapLab Slot Overview
A mad professor, Dr Mayhem, and a wild fuzzy ball called Zappy are the main characters in this feature-filled offering from ELK Studios. The base game grid is 7x7, and wins are created by five or more identical symbols connected orthogonally. When they do so, winning symbols apart from Zappy and feature symbols are removed and replaced in an avalanche, whilst remaining symbols except Zappy and Dr Mayhem move upwards until they reach a resting position.
There are a number of special symbols which create features in the absence of a standard scatter symbol. These features include an extra symbol drop, extra wilds, 2x2 symbols, expanded wild or payout symbols, and additional Dr Mayhem symbols that get zapped.
There is also a monster meter at the side of the reels that counts collected symbols and awards features once full. These are indicated by the colour of the meter and on the fifth fill awards all monster features via Shockwaves.
