XO mimics x's and o's. Played on a three by three game-board the player must get three in a row before the opponent.
XO is designed to improve the players ability to "think ahead", the players ability to mentally anticipate different/multiple outcomes, and finally the ability to respond in a flexible and adaptive manner when presented with relevant information.
Thank you for downloading XO, we hope you enjoy the application.
