X and O – хрестики-нулики онлайн

Tic-tac-toe on squared notebook paper, but you draw your own mark by hand, in blue biro: anything you like. Against the computer or with a friend. Free.

Pick a square and draw your mark in it, with a finger, a mouse or a pen: a cross, a heart, a smiley, anything you like. Your ink is always blue, and your first drawing becomes your signature in the margin.

The computer answers in red, with a doodle of its own that changes every game: a spiral, a star, a little sun. Easy, or unbeatable. Two on the same phone, the second player draws their own mark too, in red. Three in a row gets struck through in pen, and the score is kept in tally marks.

Your drawings stay on your device.
