What is Regex Crossword?
Regex Crossword turns regular expressions into grid puzzles, where every row and column is a pattern you must satisfy. It starts with gentle tutorials and builds up to fiendish double-cross and hexagonal grids, and players can also share their own puzzles. It is free to play in the browser.
Pros: what Regex Crossword does well
- Makes regex genuinely fun
- Gentle tutorial levels
- Community-made puzzles
Cons: where it falls short
- Later puzzles get very hard
- Not a reference you can look things up in
Who Regex Crossword is for
Developers who want to get comfortable with regular expressions by practising.
Who can skip it
People who just need a quick regex tester.
