Learn the rules of Tic-Tac-Toe

Bring this focus to a round

After a move, check what changed. Decide which rule explains the new state before acting again. Keep the objective visible.

Your goal

Complete a row, column or diagonal of three marks. If the board fills without a line, the round is a draw. An attractive position is not enough unless the goal is met. Review the board or playing area as it changes.

A walkthrough of the rules

  1. Player 1 places a cross in an empty cell.
  2. Player 2 places a circle in another empty cell.
  3. Take turns, watching both your winning opportunities and the opponent’s threats.
  4. The board stops accepting moves when a player wins or the game is drawn.

The controls to know

Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. Check any mode label before starting.

A useful example

Two crosses in the top row threaten a win in the remaining top-row cell. Use the example as a guide rather than a substitute for reading your board. Keep the game’s format in mind.

Check this before moving on

You cannot replace a mark that is already on the board. Compare the situation with the worked example. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
