This add-on cards are on for Harry Potter fans in any case something! Some questions are really tricky, even for many years Harry Potter expert! However, to complain about is the amount for this price. After a few times playing one meets already from time to time on a question which already had, especially if you play in a bigger group. It is just an extra edition with no board or other frills but even for an extra edition this failed skimpy! As a big fan, I still have to give 4 stars because playing makes it really fun, the amount of cards (100 pieces) not only fits easily at the price!
