How to play Tic Tac Toe
Play Tic Tac Toe online for free. Place X and O, plan your moves, and be the first to make three in a row on any device.
Objective, rules, and result
Players alternate placing X and O in empty cells. The first horizontal, vertical, or diagonal line of three wins; if all nine cells fill without a line, the game is a draw.
How to play
- Choose an empty square to place your mark.
- Take turns placing X and O on the board.
- Make three marks in a row, column, or diagonal to win.
Controls
Keyboard and mouse: Click an empty square.
Touch: Tap an empty square.
Shortcuts: U: undo.
Strategies to try
- Take the centre when it is available because it participates in four winning lines.
- Before attacking, check whether the opponent already has two marks in one line and block the open cell.
Device and accessibility notes
Select cells by click or tap and use U to undo an eligible move. Marks use both letters and visual position, so play does not depend on colour or audio.
Use the Settings control above the game to turn sound or vibration off and to reduce interface motion. Expand mode can provide a larger play area. Records are stored only in this browser when storage is available.
