There's no doubt that we've all wasted some time in class with a scrap of paper, a classmate, and a little game of tic-tac-toe.

XO is a computer version of this classic game, which challenges you to compete with the program's AI to line up 5 markers in a row.

XO allows you to import your own markers into the game, giving it a personal touch.

Whether you like games that make you think, or are just looking for something to kill time, XO is a good option.
