Mazes are events where players can earn monsters and other cool rewards by moving through different paths in the maze.  To progress, you need maze coins.

Maze coins can be collected by performing various actions in the game like collecting gold and food, fighting in multiplayer mode, breeding, hatching, and feeding monsters.

•   Maze coins earned during one event will not carry over into another maze event.
•   Players have a "pool" of maximum maze coins they can collect for each action in the game. The pool refills over time reaching a maximum after 4 hours.
