In Monument Valley, the player leads the player-character princess Ida through mazes of optical illusions as she journeys to be forgiven for something. The game is presented in isometric view and features puzzles based on visual tricks and dead-ends. The player interacts with the environment to find hidden passages as Ida progresses to the map's exit. Each level has a different central mechanic. Interactions include moving platforms and pillar animals, and creating bridges. The player is indirectly cued through the game by design elements like color.
