A word puzzle where you can prove the answer
Par tells you the exact number of placements required to make the target word from the starting word. Ops tracks your placements.
Hard constraints
The puzzle gives you hard numerical and structural constraints - not partial feedback.
That makes it possible to reason to a single target word.
A different kind of satisfaction
Solving feels like locking in a proof: once you see it, you can explain it.
If you're tired of brute-force guessing, SCHEMA is designed for you.
