About Seven Letters Challenge
Each round has seven distinct letters, at least one fair pangram and a manageable core
list. Sharing the puzzle sends your friend the same set of letters.
The core/bonus split is generated deterministically from wordfreq-unavailable English frequency data (CC BY-SA 4.0); it changes what completion requires, not which words are accepted. This is an independent game. Use the solver
if you'd rather see every matching word in this site's list for a specific puzzle, or
use hints if you want help without spoilers.
