Terrace (Dutch Flatmates + 159 sudoku)
(Eingestellt am 24. Juli 2025, 20:44 Uhr von Qodec)
- Sudoku: Each row, column, and region indicated by thick borders in the grid must contain the digits 1 to 9 once each.
- Even: The cell with the gray square is even.
- Dutch Flatmates: Every 5 must have a 1 directly above it or a 9 directly below it. It may have both, but it doesn't need both.
- 159: Digits in column 1 indicate the column in which the digit 1 appears in that row (e.g. if r4c1 is a 6, r4c6 is a 1). The same is true of column 5 and the digit 5, and column 9 and the digit 9.
- XV pairs: An X between two cells means that the digits in those cells must add up to 10. Not all possible X clues are necessarily given.

Nice break-in and a very smooth solve (except where I completely forgot the Dutch flatmates rule). Thanks!

Very nice :) Great timing too, as next weeks Dutch Flat Mates from me also has a little bit of column indexing!

Beautiful construction, I don't tango with many 159 puzzles but the interactions with Dutch flat mates was interesting! Thanks for setting, a satisfying solve.

What a nicely crafted puzzle with such an unexpected yet funny turn of event in the middle of the solve!
DFM and indexer 159 really have some funky interactions huh x)
