Regex Arcade

Regex Arcade is a bunch of small games that teach you regular expressions by making you actually use them. Type a pattern, watch it hit things.

There's a proper academy if you're new. A tower defense mode where you program turrets with regex and sloppy patterns shoot your own allies. Artillery, where the lazy . will end your run in seconds. 18 holes of regex golf where the shortest pattern wins, plus a new hole every day you can share. And if you'd rather think than type fast, Contracts gives you real-looking data, a written spec, and no timer. One perfect pattern, like it's your day job.

There's also a coach. It keeps track of your bad habits and will absolutely call you out for writing [0-9] when \d exists.
