What did you make of that last puzzle game? The one where everyone's whole team had to reach the top of that column without brooms?

I saw that some of the Hufflepuffs were trying to levitate each other up there.

Did yours have a loose brick, too, though? Ours did. We cast a banishing spell on it and the whole tower collapsed, so we could all touch the top. And the examiners said that was good enough.

How did your lot solve it?
