Tic tac toe vs computer
One player. One AI. Pick a difficulty and tap. Easy leaves openings; Medium fights back; Hard punishes slips; Impossible plays perfect — expect draws if you also play well. The point is a clean single-player board, not a fake “unbeatable download.”
This URL loads vs computer. For a human across the table, use 2 player.
When
When to use
Solo practice; you searched vs computer / vs AI / against computer; you want difficulty you can feel.
When not
When not to
Two humans on one device → 2 player. You want win theory → how to win. You want ultimate → ultimate.
Defaults
Assumptions
Classic 3×3. You are X by default. AI runs locally in the browser. Impossible ≈ perfect play (minimax).
Steps
How
- Set difficulty (Easy → Impossible).
- Tap an empty cell; wait for the AI reply.
- Use Hint if you want a reasoned suggestion.
- New game to retry the same level or bump difficulty.
Worked notes
Examples
- Easy AI ignores a fork setup → you take the fork and win
- Impossible answers every threat → you both fill the board → draw overlay
Watch-outs
Gotchas
- “Hard” on random sites sometimes means nothing; here levels change move quality.
- This is not a Google Games / doodle mirror page — same genre, our board.
- If you only wanted pass-and-play, switch to 2 player.

FAQ
Common questions
