Tic Tac Toe

Tic-Tac-Toe is a 1993 Macintosh shareware implementation of the classic three-in-a-row pencil-and-paper game, written by Jordan Pinsker. The release supports both single-player matches against the computer and head-to-head games between two humans sharing the same Mac, packaged in a no-frills System 7-era interface.

Gameplay

The rules are the familiar ones: take turns claiming squares on a three-by-three grid and try to line up three marks in a row, column, or diagonal before your opponent does. Matches are short and reset quickly for another round.

Modes

Two play modes are offered. The computer opponent provides a quick solo game, while the two-player mode hands off control between players using the same mouse and keyboard.

System Notes

This is a small, lightweight program typical of early-1990s Macintosh shareware: it runs on black-and-white and color compact Macs of the era and makes minimal demands on RAM or disk space.
