Tic-Tac-Toe

The classic three in a row. Play against a friend and show your strategy.

1. Get three of your marks in a row: across, down or diagonally. Two players take turns on the same device.
2. Tap or click an empty square to place your mark. X always goes first in every round, and the line above the board shows whose turn it is.
3. If the board fills up with no line, it's a draw. The scoreboard tracks X wins, O wins and draws; Next round keeps the score and Reset all clears it.
4. Since X always starts, swap who plays X each round to keep things fair. Before chasing your own line, check whether your opponent has two in a row and block it.
