This screen shot is of the medium-ly hard level. Easy has only 6 cards. At first they’re just touching the cards to see what happens. Even after they get a pair — they’re still just randomly selecting cards with no obvious purpose. The reasoning part — where you realize that once you know what a card is — there is no point in selecting it first — comes much, much later. But they are still quite pleased when they can match all the pairs. 18 months is a little early to master this — but they can certainly start playing around with it then.
