This page contains experimental puzzle designs and prototypes that I've worked on but haven't released as full collections. These are printable PDF files that you can download and try out.
I make a lot more puzzles than I publish on the front page. This is because I don't want to overwhelm you with too many options. I know! Too late for that, right?
Anyway, if any of these puzzles appeal to you, let me know, and I'll consider doing a longer run and promoting them to the front page!
