About Regex Rescue

Regex Rescue is a short daily puzzle: match the strings that should match, reject the rest. Every day everyone gets the same challenge so you can compare results. Beginner uses multiple choice; Intermediate and Advanced let you type your own pattern.

Why it helps

• Build reflexes for anchors, character classes, and quantifiers.
• Recognize the wrong answers people commonly write.
• Use the related Regex Generator & Tester for real work.
