Is it possible to make Kropi so that it has either "only white dots" or "only black dots".

Seen two with "only white dots", but I couldn't solve either of them so I don't know whether that was a mistake or my lack of knowledge. (sudokumania site)

The twist is - when we apply only one part of rule (consecutive or double-half), we tend to forget that the other rule (that in MUST NOT be double-half or consecutive) so we tend to commit mistakes. A good example of habit bringing blindness.

If it is possible to make that please give a few on this site.

Thanks.

A 6x6 solution with only white dots could be this:

123456
435612
652143
561234
346521
214365

But maybe I missed something.

It's a nice idea, but the 'negative' rules already cause enough confusion to a significant minority of players so I don't think Puzzlemix is the best place for this. You could certainly create both variations, though, as JoergWausW has I think shown. You could make the black-dot-only ones by opening a Non-consecutive from Puzzlemix and labelling the kropki dots, for a start.

You can always try to invent new kinds of puzzles.

I'd lika a combined "Wraparound Non-consecutive Killer Kropki Sudoku-X", please.

Or a 17x17 Hitori - and after solving it, the numbers go away. The black squares of the solution remain and become the hints for a Kropki Sudoku (without white dots) played on the same grid only in the odd rows and columns (the hitori would be boring, though).

Or combine Hanjie with Kakuro: The Hanjie grid is filled with numbers, the clues shade some squares - only those are valid for the Kakuro - unshaded cells have to be refilled according to the found Kakuro clues....
