How to play Tic‑Tac‑Toe
Tic‑Tac‑Toe (also called Noughts and Crosses or the XO game) is played on a 3×3 grid. Players take turns placing X or O in an empty square. Make three in a row row, column, or diagonal to win. If the board fills and no one has three in a row, it's a tie.
- First move: center or a corner are strongest.
- Block lines of two immediately.
- Create a fork (two threats at once) to force a win.
Tic‑Tac‑Toe is a zero‑sum game: with perfect play from both sides the result is a draw.
