About the game
Classic noughts and crosses over three rounds. The first to line up three of their symbols wins the round. Three rounds decide who is better, so one lucky game is not enough.
Noughts and crosses, also called tic tac toe, is the game everyone knows from the back of a school notebook: a three by three grid of crosses and circles.
