Modulo-Region-Sum
(Eingestellt am 21. Juni 2025, 08:15 Uhr von lcy.30)
- Modulo-Region-Sum Lines: Along a teal line, every set of three sequential digits contain a complete set of residuals modulo 3, i.e., one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}. Box borders divide each teal line into segments with the same sum.
- Kropki Dots: Cells separated by a black dot have a 1:2 ratio.
Try the puzzle on the SudokuPad app by Sven Neumann.
Hint: The property of modular lines combined with the region sum lines will help you determine the sum or possible sums of some line. The black dots are used to determine the remaining digits.
Lösungscode: Row 9, from left to right.

Very neat puzzles with some surprising deductions that one needs to work out.

This felt a lot harder than 2 stars to me, so I have even given 4 stars for difficulty. But while being tricky, it was super interesting to work out the interactions. Thank you for the fun puzzle, Icy.30!

One tricky step in the mid solve justifies a 3* in my opinion, still very nice
