About This Game

Three in a row never goes out of style. This clean digital version of the classic pencil-and-paper duel, known to many as Tic Tac Toe or Noughts and Crosses, pits you against a friend or the computer on a three-by-three grid. Claim X, place your marks, and race to line up three in any direction before your opponent blocks the path. The rules take ten seconds to learn, yet the strategy of forcing double threats can take much longer to master. With quick matches and zero setup, it is the perfect micro-battle for siblings, coworkers on break, parents and kids, or anyone with two minutes and a competitive streak.

How to Play

Click or tap an empty square on the three-by-three grid to place your mark. You play as X, and your opponent, whether a friend or the computer, plays as O. The first side to line up three marks across, down, or diagonally wins, and a full grid with no line is a draw. Tip: take the center square first whenever it is open, it touches the most winning lines. Tip: create two winning threats at once so your opponent can only block one.
