About

Three in a row wins. Play two-player on the same screen, or pick a difficulty for a computer opponent. The hard mode plays a perfect game using minimax, so you can only ever draw against it.

How to use

  1. Pick a mode (two-player or vs computer).
  2. Click any empty square to mark it.
  3. First to three in a row wins.

FAQ

Can I beat hard mode?+

No. Hard mode plays a solved game. The best you can do is draw.

Does it remember my score?+

Yes, the win/loss/draw count for the current session sits below the board. It resets when you reload.
