A hidden law silently divides words into resonant and silent, and you can never ask what it is. You can only test, watch, and deduce.

How to play
A secret rule judges every word as either resonant or silent. You feed it words and watch how they're sorted, building a theory of the underlying law from the pattern of answers. When you think you've cracked it, prove it by predicting which side new words fall on.
Submit words and observe whether each is judged resonant or silent.
Form a hypothesis about the hidden rule from the accumulating evidence.
Confirm your theory by correctly predicting how fresh words are sorted.
Game modes
Daily, one shared hidden rule for everyone each day.
Practice, endless fresh rules to test your deduction.
Difficulty, choose Easy, Medium or Hard to set how subtle the law can be.
Controls
Desktop: type a word and press Enter, or click the on-screen controls.
Phone & tablet: use the on-screen keyboard and tap to submit, fully touch playable.
Tips & strategy
Change one thing at a time, test words that differ by a single feature to isolate the rule.
Don't trust an early theory; deliberately try words that would disprove it.
Track both sides, what stays silent is as informative as what resonates.
