The best way to learn Regular Expressions is to play with combinations. Our game introduces the parts, then challenges your ability to put them together. In Expressions, you'll solve a series of sorting puzzles, using real regular expressions to sort lines of text (strings) into "match" and "don't match". Most levels are generated dynamically, to ensure there's replay value even in lessons you've beaten repeatedly.
