Tic-Tac-Toe

Classic noughts and crosses for two players sharing one device. X goes first, players take turns, and the first to line up three marks — across, down or diagonally — wins. The winning line lights up.

1. Player X taps or clicks any empty square.
2. Player O takes the next turn, and so on.
3. Using a keyboard, move between squares with Tab and place a mark with Enter or Space.
4. Press "Play again" to start a new round.
