Diagonal is a game. The object is to move your three pieces to one of the two diagonals. You move your piece by mouse. "Mac" moves his piece automatically.
Requirement
You need System 7.0.1 or later. You don’t need a color monitor. Diagonal is best for 256 colors and BlackWhite (So DON'T use 256 Grays). I've tested it on a IIfx and PowerMac 6100.
Distribution
Diagonal is freeware. Report any bugs or suggestions for improvement to me at guoniu@math.u-strasbg.fr. Thank you.
