Tic-Tac-Toe is the classic 3x3 grid game of X's and O's — quick to learn, impossible to fully solve if both sides play well. Take turns placing your mark, and be the first to line up three in a row, column, or diagonal.
Click or tap any empty square to place your mark. Play against a friend on the same screen, challenge a computer opponent across three difficulty levels, or start an online match and share a room code with a friend to play from separate devices.
Take the center if you can, otherwise a corner. Always check whether your opponent has two in a row before making your own move; a perfect game from both sides always ends in a draw.
Versions of this three-in-a-row game were played in the Roman Empire, and it is still known as noughts and crosses in many countries.
