About Tic-Tac-Toe
Tic-Tac-Toe is a compact game of creating and blocking three-in-a-row lines. Play against a perfect computer or share one screen, and learn to recognize forks where one move creates two winning threats.
Tips for a better game
- Take the center when available because it belongs to four possible lines.
- Block a fork before it forms; blocking only one line afterward is too late.
