3dtictac

3D Tic-Tac-Toe 1.0.6 is a Macintosh take on noughts-and-crosses played in three-dimensional perspective, written by John Lindal at Caltech and posted to Info-Mac in October 1992. The board is rendered as a stack of grids, and players try to line up marks across rows, columns, columns of cubes, and the long diagonals.

Game Modes

You can play against a human friend, against the computer, or set the computer to play against itself for a hands-off demonstration of its strategy.

Compatibility

Version 1.0.6 was specifically updated to be compatible with the Quadra 040 cache, addressing a common source of crashes on early 68040 Macs running software written for earlier 68k chips.
