We have played many times with these cards since I bought them last year. Although it says for ages three and up, my little one has been entertained by it since he was 18 months old. Some cards got damaged because he put them in his mouth, as they are made of cardboard, but I fixed them with tape and they still work fine. The images on the cards are clear, and with the parent's cooperation, the game becomes very enjoyable. We sit with the cards mixed up in front of us, and I say to him, for example, "what do we open with keys?" and he finds the lock. I recommend it because it is simple, affordable, and helps children to solve simple puzzles with two pieces at a time, but mainly to associate the images they see.
