Tic-Tac-Toe

Tic-Tac-Toe — noughts and crosses against a genuinely unbeatable minimax opponent, plus a beatable easy mode and two-player on one screen.

A faithful digital board game with a built-in computer opponent, rules help, and a clean single-file build. No account, no ads, no tracking; works offline once loaded.
