Game Guide
Learn the rules, token colors, hints, and practice flow before you start solving code patterns.
Core Loop
Codle gives you a programming prompt, a language, a difficulty, and a target token count. Each guess is a single code pattern. After you submit, the game checks the structure and shows exactly which tokens are locked, misplaced, or rejected.
The token is correct and already in the right position.
The token belongs in the answer, but not in that slot.
The token is not currently matched by the target pattern.
Daily mode gives everyone the same deterministic challenge for the date. It is built for streaks, sharing results, and one focused puzzle per day.
Practice mode starts fresh random puzzles on demand. Use it to learn feedback patterns, test syntax instincts, and build speed without waiting for tomorrow's daily.
Some challenges care about the shape of the code more than the exact variable name or literal. Placeholder tokens let Codle accept equivalent structures while still checking consistency.
__IDENT__Any valid variable or function name__STRING__A quoted string literal__NUMBER__A numeric literal__BOOLEAN__A true or false literal__VALUE__An identifier, literal, or expression valueCodle currently includes JavaScript, TypeScript, Python, and C++ puzzles. JavaScript, TypeScript, and Python challenges can use parser-backed structural checks, while C++ puzzles use token-pattern validation.
