In Tic-Tac-Toe you take turns placing X and O on a 3×3 grid, trying to get three of your marks in a row, column or diagonal.
X moves first. The first to complete a line wins the round, and a full board with no line is a draw. Good play means blocking the moment your opponent has two in a line and setting up two threats at once, which is why the centre and corners are valuable. Play the computer on three levels: Easy mostly plays at random, Medium sees wins and blocks, and Impossible searches every line and never loses, so a draw is the best you can do. Choose X or O (the computer opens if you pick O), or play a friend on the same device. X wins, O wins and draws are kept on the scoreboard.
