Our son asked for this for his 5th birthday.  Like some other reviewers have said, the board game itself is nothing spectacular. But, both our son and his 3 year old sister have had a lot of fun putting together the "mousetrap" contraption and making it work. For the most part it has worked much better than I expected for mass-produced cardboard and plastic.  Our 5 year old can pretty consistently put it together by himself and make it worth with only minor assistance.  The 3 year old needs help putting it together, but gets a big kick out of making it go once together and the little kinks worked out.  All in all, I think this is a good purchase for kids this age or a bit older.
