Amaze (1976)

First, each player draws a maze on a 6x6 grid using the pads of blanks included with the game. Players then work their way through their opponent's maze by asking yes-or-no questions, Battleship style. For example, a player may ask "Is the entry square on the North side?" or "May I move from square 24 to 30?" You current location is marked by a figure. When a player runs into a roadblock, he puts up a wall on his grid. The player who finds his way to the end square first wins.
