You can tap the Activity Overview on the top right, and select Moving Maze under the Get Stronger tab as illustrated below:


You need to defeat randomly generated monsters in each room, find the exit leading to the next room and repeat. At the end of each level, you will need to defeat the final boss to complete the level.

You can select a buff among 3 random ones after defeating the monsters in each room. These buffs are stackable and will make you increasingly stronger throughout the level.

Defeating the boss of any level will reward you with the First Time Completion Reward of that level to your mailbox. Revisiting completed levels will only yield basic completion rewards.
