Features
Monster Meter
The Monster Meter counts the number of collected symbols and awards random Monster features or random feature symbols when the meter is full. The fifth fill activates Shockwaves, which awards all Monster features.
Feature Symbols
Feature Symbols can drop in during any symbol drop or be awarded by the Monster Meter. The features are activated after the symbol refill and upgrade, replace or convert symbols of the game grid.
Zappy
Zappy is wild and jumps to a new random position when he is part of a win. He zap attacks all Dr Mayhem symbols off the game grid, leaving a Wild Symbol behind and increasing his multiplier. Zappy can expand up to 2x2, 3x3 or 4x4 during the last zap attack
