Ever since I saw the original Wrogn puzzle by DiMono, I had wanted to have a go at setting one myself - but could never find anything to my liking. After solving some more recent efforts (this one by Niverio in particular), I was finally inspired. I was aiming for something relatively minimalist (for a Wrogn puzzle at least) and am pleased with how it turned out. Happy solving!

Standard Irregular Sudoku rules apply but all clues given are Wrogn!

Specifically:

- Digits on thermos cannot repeat and must not increase from bulb to tip (branching thermos are considered separately i.e. digits can be the same on separate tips, but the bulb must be greater than all tips)
- Digits on a white dot must not be consecutive
- Digits on an X must not sum to 10
- Digits on a V must not sum to 5
- Adjacent digits on a green whisper line must not differ by 5 or more
- All digits in quadruple clues must not be in the adjacent four cells (note: with multiple digits, only one digit can be missing for the clue to be wrogn)
- Numbers on the outside are not valid skyscraper clues.
(Skyscraper: Clues outside the grid indicate how many numbers are "seen" along the row/column. Numbers are visible only when larger than all numbers that appear before it along the line of sight)
