The random generator next to the console sometimes generates boards that violate the precondition that there will be one winner or a draw by generating boards with 3 X's and 3 O's in a row. For instance: XOO XOX XOO This would not appear in a normal tick-tac-toe game because the game would end when the first line of X's or O's was made. This does not affect the actual exercise or checking mechanism as far as I can see.
