Tic tac toe with AI and multiplayer

Tic tac toe with AI and multiplayer brings the timeless pencil-and-paper classic into the browser with two distinct ways to play. Challenge a friend sitting beside you, or take on an artificial opponent that won't let a single diagonal go uncontested.

The AI mode offers a genuine mental workout — careless moves get punished quickly, and finding a winning line requires actual foresight rather than luck. Multiplayer mode shifts the dynamic entirely, turning every match into a quiet battle of wits between two humans reading each other's intentions.

Clean, distraction-free, and immediately familiar. Sometimes the oldest games hold up best precisely because the tension never ages.
