Whack the moles before time runs out!
You're X. Beat the computer!
Classic Tic-Tac-Toe: take turns placing marks on a 3x3 grid and try to line up three of your own in a row, column, or diagonal before the computer does. You're always X and the computer is O — who moves first is randomized each game. Be warned, this computer opponent plays perfectly, so the best possible outcome is a draw.
