RegHex turns regular expressions into crosswords. Fill rectangular or rotating hexagonal grids until every line satisfies its clues. Tutorials, hints, live clue feedback and a searchable reference help you learn as you play. Try daily puzzles, track streaks and best times, or create a puzzle, check that it has one solution and share it as a text code. Built-in puzzles work offline without a RegHex account. Free on Mac, Android and Apple Vision Pro; iPhone and iPad are awaiting release.
