DoppLKänger
(Eingestellt am 2. Dezember 2025, 18:59 Uhr von ChinStrap)
My first Doppelgänger, set for a Setting Saturday prompt about making approachable ones for solvers new to the format. This may be on the upper end of that, but I hope you all enjoy! Thanks to all that tested!
DOPPELGÄNGER SUDOKU:
- Fill each cell of the main 9x9 grid such that every row, column and 3x3 box contains a 0 and eight different digits from 1-9.
- No two rows, no two columns and no two boxes may be missing the same digit.
- For each 0 in the grid, the digits missing in its row, column and region must be three different digits.
- The notes area outside the grid must filled in with the digits that are missing from the corresponding row/column/box.
DOPPELGÄNGER LITTLE KILLERS:
- Digits along clued diagonals sum to the given total.
- Diagonals also include seen cells in the row/column/box notes areas.
- Faint lines have been drawn to help follow diagonals.
All feedback (positive or critical) appreciated!
Lösungscode: Row 9, including its missing digit at the end (10 digits total)

It's great to see the variety of Doppelganger puzzles being made now, I have loved this ruleset since solving Kafkapharnum's masterpiece "Buttered Cat Paradox".
For this one I struggled a bit as I find Little Killer quite hard, but it was well put together, thank you!

Very clever puzzle! It took me over 1 hour to figure out how to start. But I truly enjoyed a lot after that. Thanks for sharing! Definitely five stars for me.

now it worked, but the discription for the solution code doea not explicitely mention row 9...

Sorry I see now. I had stuff accidentally in the German section.

well - I am intimidated how to set the solution code?

Not sure what you mean? The grid has 9 digits in row 9 and the 10th digit is the missing digit in the row (the one in the notes column)

Having tried two versions of this, I can confirm this has been carefully crafted and tweaked to be a really nice and approachable Doppelganger! It's hardest steps (which are never too hard, and always satisfyingly elegant) are not very Doppelganger heavy anyway, so if the genre intimidates you, don't be intimidated by this puzzle!
