I'm surprised nobody's mentioned the other Regex Crossword [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. 0: https://regexcrossword.com/ 1: https://news.ycombinator.com/from?site=regexcrossword.com 3: https://regexcrossword.com/playerpuzzles/8cbea27f-c4c5-4d11-a509-6a622ba01107. - Source: Hacker News / 8 months ago
