Memory

Six pairs, twelve tiles, dealt from a set of eight animals. Your child turns over two at a time. A matched pair stays face up; an unmatched one turns back after about a second, which is long enough to look at and short enough to keep hold of. The game ends when every pair has been found, and that is the only way it ends.

There is no timer, no score and no best time to beat. Nothing is saved either, so the next board is a new one rather than yesterday's already solved. The animals are drawn rather than set as emoji, so they look the same on your phone as on anybody else's, and they are eight unlike silhouettes rather than eight of one kind — at tile size, that is what makes a pair findable instead of a guess.
