You all know the game, except this one we've ramped up a notch! There are many more ways to get that 3-in-a-row! Get three X’s in a row (horizontal, vertical, or diagonal) before your opponent gets three O’s! 3D knots & crosses is an extension of the classic naughts and crosses game. Playing it well help you see objects in 3-Dimensional space also called "spatial awareness" - plus its also just honest good fun! A wonderful twist on the favorite tic-tac-toe game!
