What is Making That Noise?

(Published on 13. September 2025, 20:39 by Zibl)

What is making that ruckus right now? Can you find out what it is?

Rules:
1. Normal Sudoku rules apply. Place the digits 1 - 9 once each in every row, column, and box.

2. JAPANESE SUMS: Shade some cells such that the clues outside the grid indicate the sums of the digits in continuous blocks of shaded cells in the respective row or column. Blocks have to be separated by at least one unshaded cell.

3. KROPKI: Digits separated by a white kropki dot have to be consecutive. Not all dots are given.

To those complaining about the "long" solution code, don't forget you can copy/paste, option available in advanced settings of sudokupad. It would be worse if it was 2 columns

Cool puzzle. An unusual variant, but I enjoyed it.

The solution code has no business being that long, though.
