Tic-Tac-Toe

The original quick-fire classic. Take turns marking a 3×3 grid; get three in a row — across, down, or diagonally — to win. You play X and go first. On Hard the AI plays perfectly (the best you can do is draw), so switch to Easy for a beatable opponent.

Your turn — place an X. AI:

Wins 0 · Losses 0 · Draws 0

How to play

Click any empty square to place an X. The AI replies with an O.
Line up three of your marks to win. Easy makes the occasional mistake; Hard never loses.
