I bought this for my granddaughter aged about 20 months at the time. It has been played with ever since and she is now three and a half. We started using the cards for word recognition, then finding two of a kind, now finding something beginning with a certain letter and just recently she is beginning to use them for the pairs game as originally intended. It can be made as easy or as difficult as you wish by the number of cards you include. It has proved to be a very good purchase.
