Double or Sum-thing
(Eingestellt am 27. September 2022, 19:27 Uhr von josh_johnson)
Almost normal Sudoku rules: Place the digits 0-9 so that each row, column, and box contains each digit exactly once.
Kropki (no negative constraint): The value of cells separated by a black dot have a 1:2 ratio. The value of cells separated by a white dot have a difference of 1.
Doubler cells: Every row, column, and box contains exactly one doubler cell. Each digit from 0-9 is doubled exactly once. The value of the cell is doubled, for the purpose of Kropki clues.
Sum-thing cells: One cell in every row, column, and box is a "sum-thing" cell, containg two digits. The value of a sum-thing cell is sum of the two digits in the cell.
A cell may be both a doubler and a sum-thing cell. In this case, the value is double the sum of the two digits in the cell. For example, the value of a a doubled "sum-thing" containing a 3 & 5 has a value of 16.
Lösungscode: Row 4, then column 8. (20 digits, no spaces. For the "sum-thing" cells, enter the lower digit first)

A wonderful puzzle!
It's fun to see how ridiculous otherwise combinations of dots turn out to be possible because of the doublers and sum-thing cells, and to track unusual cells over the grid.
