- Irregular 10-sudoku rules apply: place digits from 0 to 9 once each in every row, column and region.
- Shade ten cells so that there is exactly one shaded cell in each row, column and region. Shaded cells cannot contain repeated digits. If D is a digit in a shaded cell the value of that shaded cell is -D. Values of non-shaded cells are the same as the digit they contain.
- The region borders cut each blue region sum line into connected components with the same value sum. (That same sum may differ between different lines.)
- Values in cages must sum to the indicated total. Digits cannot repeat inside a cage.
- Clues outside the grid show the value sum of the indicated diagonals.
Online in Sudokupad
Solution code: Column 5 top to bottom, followed by the shaded digits top to bottom.
