About the game

Tic Tac Toe – MarketJS is a classic Board game where you race to line up three marks before your opponent does.

How to play

Pick 1 Player mode to play against the computer or choose 2 Players to play locally with a friend, then choose X or O. Tap an empty square on the 3×3 grid to place your mark, and take turns until someone gets three in a row across, down, or diagonally. Start in the center or a corner, block your opponent when they get close, and change the difficulty when you want a tougher match.

Tip Take the center if it is open, then try to set up two winning lines at once so your opponent cannot block both.
