Rules:
Write exactly one integer from 1 to 7 in each cell, such that in every row and column each number appears exactly once.
If an integer is double of an orthogonally immediately neighboured integer, there is a filled (black) circle between these two cells.
If the difference of two orthogonally immediately neighboured integers is 1, there is an unfilled (white) circle between these two cells.
All possible circles are given!
Solution code: First row (left to right), then second column (top to bottom)

@chain.reader: This is intended and the "Kniff": In one of your possibilities, the last sentence of the rules is not fullfilled ;)

@Dotty: I can ensure you that the subtility is not lost in translation. You just have to read the rules very carefully and take them literally ;)

There is probably a subtility in rules that doesn't appear in translation because what I read are standard kropki's rules and there are several answers

Labels den neuen Regeln angepasst:
Nach der neuen Beschreibung der Labels trifft "Mystery" meiner Meinung nach nicht mehr zu.
By the new description of labels, "mystery" does not fit anymore in my opinion.

@Lizzy01: Of course I read them all, but I have to admit that I'm actually not that big fan of sudokus.

@CJK btw Do you read the comments on your older puzzles? I've noticed that some people on here don't seem to know that from your 'edit puzzles' page there is a 'comments on your puzzles' page button where you can quickly see any new comments on old puzzles.
I posted a comment on one of your other recent puzzles with a link to one of my puzzles I think you might like.

@Statistica: Ja, das hab ich leider befürchtet, dass die Pointe nicht so einfach zu erkennen ist :/
Allerdings habe ich die Hoffnung, dass zumindest diejenigen, die sie erkennen, sich daran freuen :D

Hübsch. Aber ich glaube, ich kann die eigentliche Pointe nur erahnen...
