I'm surprised nobody's mentioned the Regex Crossword game site [0], it's shown up on HN several times [1][2] and has a fantastic user-submitted puzzle section (that includes the MIT Mystery Hunt puzzle [3]) and a puzzle builder.<p>0: <a href="https://regexcrossword.com/" rel="nofollow">https://regexcrossword.com/</a><p>1: <a href="https://news.ycombinator.com/from?site=regexcrossword.com">https://news.ycombinator.com/from?site=regexcrossword.com</a><p>2: Most discussed posting: <a href="https://news.ycombinator.com/item?id=8674039">https://news.ycombinator.com/item?id=8674039</a><p>3: <a href="https://regexcrossword.com/playerpuzzles/8cbea27f-c4c5-4d11-a509-6a622ba01107" rel="nofollow">https://regexcrossword.com/playerpuzzles/8cbea27f-c4c5-4d11-...</a>
This is a Mystery Hunt puzzle, so solving the obvious puzzle is only the first step of solving the puzzle. You will need to do something with the puzzle solution to somehow get a word or short phrase.<p>I remember doing this one by hand over a decade ago. Fond memories.<p><a href="https://puzzles.mit.edu/" rel="nofollow">https://puzzles.mit.edu/</a>
I really love this kind of thing. I made one called 'redoku' a long long time ago. It generates random challenges. Try it here: <a href="https://padolsey.github.io/redoku/" rel="nofollow">https://padolsey.github.io/redoku/</a>
I loved this puzzle, spent hours to solve it.<p>What I don't like is the mystery hunt that follows. You don't know where to start, you don't know if the solution you found is correct, etc.<p>Even a after looking up the solution, it doesn't make me go "wow! That's brilliant". The final phrase is too short to be meaningful, it's not related to the game (at least, I can't get the connection), one of the words I didn't even know it existed in English (is it an abbreviation, perhaps? Is it American English?)...
