Not every code follows the same path.

Codle combines word logic with five cipher families. Learn the transformation, test a word, and use exact-position and elsewhere clues to close in on the answer. The hidden key changes every round.

The rules

Study the encoded word and the active rule, then reverse that transformation to recover the answer. Later rounds combine less familiar rules and require closer comparison.

What makes it different

Each puzzle asks you to understand a transformation rather than memorise a single offset, making Codle a compact test of language and logical flexibility.
