  • Patent number: 4323242
    Abstract: An electronic maze game comprising a maze which is stored electronically in the memory of a microcomputer, a four bar display which indicates if there is a wall or an opening immediately above, below, right or left of the player's present position, and four push buttons which permit the player to make a move from his present position to the adjacent position lying above, below, to the right or left, provided that such move is not blocked by a wall. A number of different mazes are stored in the game, and the player may choose to play a "beginner", "intermediate" or "advanced" game, or repeat the last game played. A two digit display tells the player at the beginning of the game the minimum number of moves required to transit the maze, and during play of the game, the number of moves the player has made.
