Announcing Regex Battle
I built a small app called Regex Battle. It lives at https://regexbattle.com and it turns regular expressions into a head to head game. You get a prompt, a timer starts, and your goal is to write a regex that meets the challenge before the clock hits zero. You can play against another person or against a bot if you want to practice solo. Regex Battle is a PvP regular expression battle game with a bot and PvP mode. Each round gives you an objective and a set of example strings. Your job is to write a pattern that matches what it should and rejects what it should not. When you submit, the app checks your regex against the round tests and shows the result. Fast and correct beats slow and almost. Simple as that.
