Seismic Hazard
(Published on 16. July 2022, 09:26 by DarthParadox)
Place each of the digits 1 through 9 once into each row, column, and 3x3 box. Cells separated by a white dot must contain consecutive digits, and cells separated by a black dot must contain digits in a 1:2 ratio; not all possible dots are necessarily given.
The brown lines are Cliff lines. Digits separated by a Cliff line must differ by at least four, and when the same line separates more than one pair of digits, the higher digits in those differences must all be on the same side of the line.

I struggled a lot with this one and had to start over 3 times! Tricky ruleset but very satisfying to solve

Very original, with a nice break-in and a rather smooth solve afterwards. 2/5 difficulty is a bit high, imho.

That's a rule I've never seen, and it had some interesting consequences.
