Floor Plan
(Published on 15. March 2022, 20:39 by the_cogito)
Rules:
- Normal Sudoku rules apply.
- Digits in red cells in columns 1, 5, and 9 give the position of the digits 1, 5, and 9, respectively, within their respective rows.
- Broken 159: ALL possible red cells are given (ie, a 2 in r2c1, ignoring that it's obviously broken in this case, would mean r2c2 CAN'T be 1, since r2c1 isn't shaded).
- Digits outside the grid are numbered rooms clues. The digits in these clues are also found N cells from the edge of the grid within their respective row or column, where N is the value of the first cell in that row or column. (for example, in this puzzle, if r1c1 is a 2, then r2c1 must be 9)

I solved your 2 "broken 159" puzzles back-to-back, and I really enjoyed both of them very much. Very nice interactions with powerful outside clues, and an incredible solve considering the amount of these clues. Thanks.

Brilliant puzzle, seems brutal in the beginning but if you carefully apply the consequences of each rule, there is a way out every time it seems stuck
