What is XO?
Check out XO! It is a modified version of the classic table game Gomoku (5 in a row). It is like a tic-tac-toe game but in XO you have to make 5 continuous X's or O's instead of 3 as in a classic tic-tac-toe game. XO is fun to play and is also a bit brain teasing, so beware of some mental exercise!
