Mattel Harry Potter and the Socerer's Stone Trivia Game Prefects Edition

Does anyone have this game and the ultimate hp trival pursuit game? which is better? how are they different? does this game only cover the first book

Can anyone give a recommendation as to this game versus the original sorcerer's stone trivia game? Thanks in advance and happy holidays!

We lost the special 6-sided die that comes with the set. What makes it special? basically we just want to know how to use as regular die instead.

How many questions are in this game?
