Master Puzzler Eric Berlin has posted all the puzzles from the puzzle hunt he and two friends created for the National Puzzlers’ League convention last weekend. It’s called Spaceportland, and all the puzzles are available for download on his website. They look fiendish. Good luck, and let me know if you manage to make any headway.
(If so, you might consider joining the NPL and making it out for next year’s party.)
