How to play Tic-Tac-Toe

  1. Take turns marking empty cells — ✖ goes first.
  2. Classic 3×3: first to get 3 in a row (across, down, or diagonally) wins.
  3. Bigger boards change the goal: 5×5 needs 4 in a row, 7×7 needs 5 in a row.
  4. If the board fills with no line, the game is a draw.

Tic-Tac-Toe FAQ

Are there bigger boards?
Yes. 3×3 as standard, 5×5 where you need four in a row, and 7×7 where you need five.
Can I play against the computer?
Yes — add a bot. It takes a win, blocks yours, and prefers the centre.
How long does a game take?
Under a minute.
Do I need an account?
No. Type a name and play — no signup, no download, nothing to install. Making an account is optional and only exists to keep your stats, nickname and preferences across devices.
Is it really free?
Yes, all of it. Every game on Board Game Universe is free to play, with no premium tier holding anything back.
Can I play on my phone?
Yes. It runs in a mobile browser on phones and tablets as well as on a desktop — there is no app to download.
How do I play with my friends?
Start a table and send your friends the link. They open it, type a name, and sit down. Moves and table chat happen in real time.
Can I play against the computer?
Yes. Add a bot to any table and it plays a proper game — useful for filling a seat while you wait for a fourth.
