Loki's Maze was first introduced in October 16, 2015 as "Loki's Maze of Mayhem".
Loki's Maze is a gigantic cavern filled with 4 mini-games for the player to overcome to reach the reward and Tuff and Ruff's Trade (which are 3 Surprise Chests of all the 3 different kinds). At first, it was a small mini-game that the developers added, however, it later became a thing. Loki's Maze will be on Berk at an exclusive amount of time until the developers develop a new Loki's Maze based on the current theme (ex: Christmas -> Loki's Maze of Cheers).
