Circuit Flow

I've been experimenting with the combo Kropki dots + Lockout line for a while and at one point I finally got a version of it, and it's satisfying enough for me to decide to share over here. For lockout line enjoyers, this one may be another fun puzzle for you :)

In my opinion, the difficulty should be on the lower side of 4/5 but I still put it at 4/5 in the final decision and of course it can be changed. I hope you enjoy!



Rules:

- Normal Sudoku rules apply: every row, column and 3x3 box contains digits from 1 to 9 each once.

- A black dot implies 1:2 ratio relationship between two cells, a white dot implies consecutive relationship between two cells. Not all dots are given.

- Blue lines in the grid with diamonds attached to them are lockout lines: Digits in the diamonds (endpoints) must have difference by at least 4; digits along the line must be different than endpoint values and must not lie between them (digits can repeat on the line if allowed by other rules).

To clarify more, the line from R2C8 goes straight in col 8 and ends at R4C8; the line from R3C7 goes through the intersection and ends at R6C9.

Good luck and have fun solving!

Lösungscode: Row 7 (left to right) and column 8 (top to bottom), 18 digits long with no space

Decided to change the difficulty back to 3/5, but on a bit harder side of it

Very lovely break-in, and as the name suggests, great flow after!

Very nice construction. Took a little thought for me to get going but once it started, it was a smooth solve all the way. I would put it in the 3-3.5 range for me (but i am more familiar with lockouts)

Very nice interactions and a pretty smooth solution path. For the difficulty, I think 3 stars is fair.
