How to play

• To set up a game of concentration (also known as memory or pairs), first shuffle the cards well and then place each card face down.
• Each player takes a turn by turning two cards over. If the cards match, then the player picks up the cards and keeps them.
• If they don't match, the player turns the cards back over. You can also play by yourself.
