Thank you for the lovely puzzle! It's the first one I've done with the entropy rule, and took a bit to wrap my mind around, but it was a lot of fun. Have been going through your puzzles, and have enjoyed each one :)

Very enjoyable puzzle! Precisely when I had exhausted the clues, the full implication of the global entropy rule on the completed grid became apparent and everything fell promptly into place. Thank you.
