Thanks Gabi!
Delimited Kropki
Solve online in
Gabi (ibag) translates all SVS's and the solving hints for this Advent series.
So a big THANK YOU to gabi!
Apply classic sudoku rules.
Only for two cells connected by a grey line, kropki rules apply:
A white circle between two cells indicates that the neighbouring digits are consecutive.
A black circle between two cells indicates that one of the digits is twice as big as the other digit.
The absence of a circle indicates that there is no neighbouring digit that is either consecutive or double.
Be aware that between digits 1 and 2 the circle can be either white or black.
The black circle in box three is valid for both of the two diagonal lines that form the letter X.
Sudokupad (no answer check)
Sudokupad (with answer check).
Solution code: Row 5

I enjoyed it until I ran out of negative constraints.

I am sorry to read that. This puzzle is perfectly solvable with logic alone. If you keep good track of the possibilities and do the right eliminations, there are no guessing or sophisticated moves necessary.

Couldn't figure out the end without bifurcation

I don't think you need to bother with a version without answer, people can just toggle the option in sudoku pad

Happy Christmas.
It's been much better than an Advent calendar. Your puzzles have been tastier than all the little chocolates!

Vielen Dank für die gut verständlichen Übersetzungen.
There‘s so much extra effort in these 25 puzzles: an approachable, yet still satisfying solve path; translations; hints; and even an (optional!) solution check. Thanks again for doing all that for us!
