50 large cards to develop memory skills in the colourful world of Cocomelon. Mix the cards and lay them face-up on the playing surface. Observe them for 30 seconds and turn the cards over. The oldest player starts by turning two cards over. Do they make a pair? If so, keep the cards and turn over another pair. If not, turn the cards face down again. The player with the most pairs wins when there are no more cards left to play.
