Some of the current players are, in the nicest way possible, really failing.

I kid, you aren't failing. Some of you just seem to be zeroing in on the wrong things and totally missing the ones right in front of you! I know that this isn't impossible, since two people have already beaten it and two more are inches from it.
So, here are some hints for those still playing:

If you haven't figured it out yet, there are things you
have to buy from Diagon Alley in order to win, don't worry, you will end this game with more money than you started with.

Remember, I tell you
everything. If you're confused about what a Professor wants you to do look over the initial PM I sent when you first walked into the room.

Some people seem confused or forgetting that each Professor has more than one thing you can do for them. I suggest you read this thread over again.

Finally, don't be discouraged! I designed this to be a bit confusing, but just read carefully and think outside the box. And, not everyone has tried to take advantage of this yet, if you really need help, ask me!
