Who doesn't like this kind of game? It helps your brain's skills and gives you more time with your kid. That's what I did with my 3 years old son. If I feel that it's time for him to learn other things, this is what we played.
We haven't finished the first page yet, for this is really serious hunt. I could not find some stuff. Pretty camouflage objects with the different colors.
He loves it and I love it. We bought spent an hour for looking at the object, and gets our eyes tired from searching.
A good Family Christmas gift from my Mother in Law last year.
