Regex Rodeo

Each herd mixes the strings you want, like emails, dates or phone numbers, with decoys that look almost right. Pick or build a regular expression and watch the matches light up live, then throw the lasso. A perfect throw catches the whole herd and no decoy.

How to play

Read the goal. Each herd says what to catch: email addresses, YYYY-MM-DD dates, order IDs…
Pick or build. Choose a pattern, or in Expert build it from token chips. Matches light up as you go.
Score. 100 for a whole herd with no decoy; otherwise 15 per catch minus 25 per decoy.
Three levels. Beginner picks among three patterns with hints. Expert builds every pattern from chips in 75 seconds. Each level keeps its own best score.

Quick tips

\d is a digit. \d{4} means exactly four digits.
Escape the dot. A dot on its own matches any character; \. is a real dot.
