Three Dee Tee is a computer game for two players. It is loosely based on the Rubik's cube game and Tic Tac Toe. The object of the game is to color three cubes in a line either vertically, horizontally, or diagonally. The computer keeps track of every winning combination and displays a box score for each player.
Three Dee Tee was written by John Stuart and published as type-in source code in Byte Vol. 7, No. 9, September 1982. It placed seventh in the BYTE Game Contest.
