Abstract: A rotating cube game or puzzle which is displayed on a computer display screen in three dimensions and is manipulated in three dimensions to expose the respective faces during play of the game or solving of the puzzle. The game or puzzle is preferably implemented on the cube in such a manner that there is continuity among the respective edges. For example, individual crossword puzzle entries are designed to wrap around the edges as desired. The letters for the sides of the cube facing the user are drawn by reading the letters stored in the appropriate three of six total two-dimensional arrays (one array for each face of the cube), and the arrays are manipulated as the cube rotates so that the right and top sides of the cube facing the user will be displayed correctly. Entries in the arrays may be spun 90 or 180 degrees, as appropriate, and then drawn in each block at the correct perspective angle.
