Rules: Normal sudoku rules apply. Divide the grid into rectangular patches. All digits in a patch have the same parity, i.e. they are either all even or all odd. A circled digit equals the number of cells in its patch. All possible circles are given. Two patches with the same number of cells and the same parity may not share an edge.
Lösungscode: Row 1, with "/" marking borders between patches (e.g. 1/357/9/246/8)

The last rule really messed me up.
At first I had misread it as something much stronger than it actually says. So I quickly got into some contradictions and did not understand what was wrong with my deductions.
Once I had re-read the rules and started over it took me a while to figure out how to even get started.
And by the time I got towards the end of the puzzle I had completely forgotten about that last rule and couldn't see how the solution could possibly be unique.
But the puzzle is still perfectly fair, one just has to read the rules correctly and not forget them :)
Beautiful puzzle with 4½ stars of difficulty.

Wow, took a long time to solve because I just couldn't see one simple deduction, but nevertheless very cool and well-put puzzle :D (also mini heart attack at the deadly pattern!)

I'm ashamed to admit how long I stared at that deadly pattern before I remembered the rules XD

Beautifully set. I was on a learning curve about the ruleset, which took time to work out - there are some cool deductions in there, and just about every consequence I could think of from the rules was part of my solve. It might be 3* for someone who has encountered the rules or intuits the logic. I think it is a bit harder than that to think it through from scratch. But a beautiful solve with plenty of nice things to uncover.
