Use a 4x4 array of 8 pairs of cards (letters A-H) to create the children’s game Memory. Initialize the deck, then shuffle and display the cards face down. Have the user select two cards and display the card face up after each selection. If they are a match leave the cards face up for the rest of the game, if they aren’t, flip them back over when the user chooses the next card. After the user has matched all eight cards they win and the game is over
