I got this for my son two Christmas' ago.  Boy, does he LOVE it.  He has mastered all the cards, but still goes back to the game.  It will really keep your child busy.  He was 6 when I purchased it and now at 8 years old it is one of his favorites.  My 6 year old is next to get it.  Absolute loved game.  A must have for a childs collection.  You can't go wrong with this one.
