The Witness

The Witness is a 3D puzzle video game developed and published by Thekla, Inc. In the game, the player explores an open world island filled with natural and man-made structures. The player progresses by solving puzzles, which are based on interactions with mazes presented on panels around the island or hidden within the environment. The player will have to determine the rules of each puzzle from visual clues and audio recordings scattered around the island. The game includes about 650 puzzles, though the player is not required to solve them all to finish the game.
