About Tic Tac Toe
Line up three Xs or Os on a 3×3 board. Play solo with three difficulty levels or take turns with a friend on one device. The score counts wins and draws during your current session.
How to play Tic Tac Toe
Tap or click an empty square, or press 1–9 in reading order. X goes first. Complete a row, column or diagonal to win. In Moving Marks, each side keeps up to three marks: placing a fourth removes its oldest. A repeated position or 30 moves ends that mode in a draw.

Tic Tac Toe tips
