Infinite Tic-Tac-Toe
Infinite Tic-Tac-Toe
Each player keeps only their last three pieces, so the board never fills up.
Infinite mode changes one rule of the classic game: when you place your fourth piece, your oldest piece comes off the board. With never more than six pieces on nine squares, the board cannot fill up, so there are no draws from a full board.
That changes the strategy. A line that looks blocked now may open two turns later. The piece about to vanish is marked on the board so both players can plan around it.
Rules of Infinite mode
- Each player's first three pieces are placed as in normal Tic-Tac-Toe.
- Once you have three pieces, your oldest one is marked as the next to go.
- When you place a fourth piece on an empty square, the oldest is removed.
- You cannot place the new piece on the square of your own oldest piece: it is still occupied when you play.
- The game goes on until someone gets three in a row.
Tips for Infinite mode
- Watch the marked pieces: the square of a piece about to vanish becomes free right after the move.
- Do not rely on an old line: if one of its pieces is next to go, the line is about to disappear.
- Build threats from your two newest pieces: they will last the longest.

Frequently asked questions about Infinite Tic-Tac-Toe
Can Infinite Tic-Tac-Toe end in a draw?
Not by a full board, since there are never more than six pieces at once. In theory a game could drag on if both defend well, but in practice it usually ends quickly with a win.
Can I place on the square of my oldest piece?
No. That square is still occupied when you move; the piece is removed after you place the new one.
