  • Patent number: 8419432
    Abstract: The Tactile Sudoku Game Display for the Blind has 4 control buttons used by the blind game player to manually direct the attached computer to change the current game square up and down and left and right. The Game Display has 27 electromechanically raised and lowered dots similar to Braille dots arranged in 3 squares each with 9 dots arranged in 3 rows and 3 columns. The raised dots in the Game Display's lower-right square communicate the current status of 1 of the 81 Sudoku game squares to the blind game player by touch. And 1 raised dot in each of the Game Display's other 2 squares communicates the column number and row number of the current game square to the blind game player by touch. The game author's given starting game squares have only 1 of the 9 dots raised; and, the blind game player touches and depresses all but 1 of the 9 dots in each remaining game square to complete the game.
