Puzzlehunt puzzles

If you've never heard of puzzlehunts, a brief idea is that they're sort of like escape rooms, but minus all the physical aspects, and generally lengthier and significantly more difficult (think a weekend-long event, rather than an hour or so). I like this primer as a slightly more extended dive into what puzzlehunts are.

I've run and contributed puzzles to a few puzzlehunts over the years, primarily Silph Puzzle Hunt. According to my personal records I've written over 160 puzzles for 15+ separate hunts, but here are some of my favourites.

I also have a soft spot for Christmas Cards, a half-puzzle, half-game "deckbuilder" I wrote for a Secret Santa-style puzzle-exchange event.

Cryptic crosswords

These are cryptic crosswords with no hunt-style "final answer", though usually they have instructions for extracting one or more phrases from the grid.
