Kroppelgangers (4x4 X-Sums)
(Published on 9. June 2024, 05:35 by Calesch)
Rules:
Normal 4x4 sudoku rules apply: in the 4x4 grid, place the digits 1-4 once each in every row, column, and box.
X-Sums: numbers outside the grid indicate the sum of the first N digits in that row or column seen from the direction of the clue, where N is the first digit seen by the clue.
Numbers separated by a white dot are consecutive. Numbers separated by a black dot have a ratio of 1:2. Not all possible dots are necessarily given.
Solution code: Bottom row of both 4x4 grids (8 digits, no spaces)

Zwei sehr schöne kleine Beispiele für X-Summen.

Really cool little discovery and fun to do in a 5 minute break. I love how both puzzles are identical except the colour of the Kropki dots, and that they have unique solutions!

I liked it, first time i do x Sum, is there an option to make double digits possible for the sums in the sudokupad?
