Tic-Tac-Toe: from controls to your first round
Start Tic-Tac-Toe by looking at the playing area and its controls. Complete a row, column or diagonal of three marks. If the board fills without a line, the round is a draw. Use the example below to understand a decision. Begin with the same-device two players mode shown on the page. Keep the game area visible while you use its controls.
One thing to notice as you play
After a move, check what changed. Decide which rule explains the new state before acting again. Notice the feedback after each input.
Your objective
Complete a row, column or diagonal of three marks. If the board fills without a line, the round is a draw. The feedback beside the game helps you follow the round. Check the rules when you are unsure.
Work through the instructions
- Player 1 places a cross in an empty cell.
- Player 2 places a circle in another empty cell.
- Take turns, watching both your winning opportunities and the opponent’s threats.
- The board stops accepting moves when a player wins or the game is drawn.
How to use the controls
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. Make sure you are interacting with the game rather than the surrounding page.
Learn from a sample situation
Two crosses in the top row threaten a win in the remaining top-row cell. Focus on why the action is allowed, not only its outcome. Choose a deliberate next step.
A useful caution
You cannot replace a mark that is already on the board. Check the rule before repeating the action. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
