Just came across this thread--wish I'd seen it sooner! There was another very short thread on the Variety Puzzles forum but nobody was posting there.
My son and I finished all but four of the puzzles--Magic Words, Institutional Knowledge, Black Girl Magic, and Mixed Doubles. It was a lot of fun, but there's no chance we'll finish by tomorrow. I especially enjoyed La Fete, Into the Words, and Resolution. I strongly recommend La Fete to anyone who loves word puzzles (which I assume includes any muggles reading this). It's a very clever series of 15 word puzzles of a type I had never done before.
Good luck to any muggles in the finals!
