Position Sums mit Kropki-Paaren
(Published on 8. February 2021, 15:41 by glum_hippo)
Fill the grid with digits 1 to 9 so that each row, column and 3x3 box contains each digit exactly once.
Digits in the first and second cell from the top and from the left are A and B. Clues outside the grid tell something about A and B: The clue closest to the grid gives the sum of A and B. The sum of the digits on positions A and B from that side is given in the clue in the grey bar.
EXAMPLE: the digits sequence 841627935 have A=8 and B=4, so A+B will be 12, and the sum of the 8th and the 4th (Ath plus Bth) digit is 3+6 = 9.
A hollow circle indicates consecutive values, a filled circle indicates a ratio of 1:2 between values. The digits 1 & 2 may be separated by either a hollow or a filled circle. Not all circles are shown.
The puzzle can be solved in Penpa+ here.
SudokuPad version.
Solution code: The digits of row 8 inside the grid, then column 9 (18 digits total, without the clue cell contents)

Hard to believe I actually found the solution path. The entry is really well hidden.
— for better or worse, I tried to keep kropki inside the sudoku grid, unattached to the edges, to a minimum. More constructions are surely possible. g_h
