How to Play â Tic-Tac-Toe
The classic game of Tic-Tac-Toe (noughts and crosses). Take turns placing your mark on the 3Ã3 grid â you are X and go first. Get three of your marks in a row, column, or diagonal to win. Choose vs Computer to play the AI at Easy, Medium or Hard (Hard uses the minimax algorithm and is literally unbeatable â the best you can do is force a draw!), or switch to 2 Players to play with a friend on the same device. Wins, losses and draws are tracked across rounds. Tap New Round to play again or Reset Scores to start fresh.
