Plus or Minus 5

Place the digits 0-8 such that no digits repeat in any row, column, or 3x3 box.
Each cell pairs with an orthogonal neighboring cell such that their sum or difference is 5. No cell can be part of two or more pairs. However, cells with a circle are not part of any pair.
Digits separated by a white dot are consecutive
Digits separated by a black dot are in a 1:2 ratio
Digits separated by an X add up to 10
Lösungscode: row 1

To respond to nunc, r6c6 does not paid with two cells. It has two neighbours it can potentially pair with, but if you paired it with both, there would be a pairless cell left over, or you'd have a group of four cells, which is also not a pair.
That was a super fun puzzle. I just chipped away at it gradually all day and it was delightful from beginning to end.

非常不错的谜题，但规则说任何单元格都有且仅有一个配对，实在是有点误导人了。
应该把那两个有两个配对数的单元格另外标出来，并且说明这两个单元格有多个配对，但它仅与其中一个数配对，另外的配对数与它无关。

The idea is nice, but the constraint that each cell pairs with _at most_ one other cell does not hold in at least 2 places (r6c6 pairs with two cells, and also r7c2).
