I found an open copy of the game at a thrift store the other day. Playing around with it solitaire Secret 'X' was the event. Todd Newton's said to win the contestant had to get three X's in a row vertically, horizontally, or diagonally. Vertically? Is that possible? It would be a risky strategy but it would guarantee a win if the player gave correct responses to both either-or prizes to win more X's.
