How to play Tic Tac Toe Ultimate

Take turns placing an X or O in an empty square. Click a square on desktop or tap it on mobile. Your goal is to complete a line before your opponent does.

In Classic mode, you need three matching marks in a row. On the bigger boards, you need four. Lines can run across the board or from top to bottom. Diagonal lines count too.

Before moving, check if you can finish your own line. If you can't, look for a square your opponent needs to win and place your mark there to block them.

Try placing a mark that leaves two different squares where you could finish a line next turn. Your opponent can block only one, leaving you another square to win.
