  • Patent number: 4572513
    Abstract: An educational game including a game board, at least one game piece and an audio recording. The game board has a serpentine path located on the top face thereof. The serpentine path is broken up into a series of connected squares. The game piece is designed such that it is moved along the path as the game is played. The audio recording contains a number of mathematical problems or other questions and the answers thereto. Each question or problem is separated from its answer by a pause of predetermined duration. Each time the player of the game answers a problem or a question correctly and within the time allowed, the player advances his/her game piece along the serpentine path. The number of squares on the path and the number of questions on the recording are equal so that if a player answers all of the questions correctly, his/her game piece exactly reaches the finish space.
