XO 对比 TicTacToe Ultimate Multiplayer 的使用情况和统计数据

You can play against the computer, a friend on the same device, or a real opponent. The goal is to make a row of three X's or O's before your opponent does. If you're looking for a new challenge, try the 5x5 or 7x7 versions, where the winning line must consist of 4 symbols instead of the usual 3.
