Four houses of Kropki

Rules: Normal sudoku rules apply. In addition to that,
- (renban) each purple line contains a set of consecutive digits in any order without repeats,
- (German whispers) adjacent cells on green lines must differ by at least 5,
- (black kropki with negative constraint) each pair of adjacent cells with digits of ratio 1:2 is indicated by a black dot.

Utterly crazy puzzle. Very difficult. Nothing too fancy going on, unlike some of your other puzzles, just a lot of very difficult negative constraint deductions. Needed a lot of thought to work through some parts, but there was a lot of very interesting logic in there as well.

Again capturing with beautiful interactions. Less difficult than others of yours, more something to work through
(for me obvoius killer like). Well done!

Much more difficult than I'd expected, tripped up by faulty logic over and over again. In the end, color-coding the digits (1248/36/579) helped a lot.

I agree with henrypijames, definitely up there with your Louis XV sudoku for the look, just waay trickier!
.........
Yeah, I actually realised it only after making it, but it really is in the same as Louis XV, happy you liked it.

My instant reaction to seeing the grid is laughing out loud - it's so funny (and beautiful, indeed).

Once again, as expected from Filuta, an incredibly beautiful construction, with some very tough deductions. The initial logic was nice, and the interaction between the four houses is admirable.
........
Thanks a lot, Tilberg.

Beautiful looking sudoku! The puzzle itself is tricky, but ultimately very nice and rewarding. :-)

Thanks, and once again for the testing too.
