Tic-Tac-Toe
Take turns placing X and O on a 3×3 grid; the first to line up three wins. Play the computer on Easy, Medium or Hard, or share the screen with a friend. Hard never makes a mistake, so the best you can do against it is a draw. The first move alternates each round, and the score is kept until you reset it or leave the page.
