Counting Sum Lines
(Published on 28. April 2026, 21:23 by mimec)
This week's puzzle combines two of my favorite sudoku rules: region sum lines and counting circles.
Previous puzzles in this series:
Rules:
- Normal sudoku rules apply.
- Box borders divide each blue line into segments with the same sum. Different lines may have different sums.
- A blue circle indicates exactly how many circles contain that digit. For example, if there is a 4 in any circle, then exactly 4 circles contain a 4.
Solution code: Row 9

I found it harder than expected for 2 stars, but very nice logic!

Very nice flow on this one, felt like setting up dominoes then watching them neatly fall.

I found this one harder than the previous two. A few actual challenges to get going, but then it flowed nicely.
