Indexed Sandwiches
(Published on 17. May 2024, 23:38 by Chad)
- Normal sudoku rules apply.
- Clues outside the grid give the sum of the digits between 1 and 9 in their respective row or column. Each digit within a clue has been replaced with a ?. All sums are greater than 0.
- The first digit from the direction of the clue indexes the 1 in the relative row/column. The second digit from that direction indexes the 9 in the same relative row/column.
- The inequality signs point towards the smaller digit.
Examples:
- If r2c1 is 6 and r2c2 is 8, then r2c6 is 1 and r2c8 is 9
- If r4c9 is 3 and r4c8 is 6, then r4c7 is 1 and r4c4 is 9
Solve here: SudokuPadSolution code: row 7 then column 6

@Marcmees -- it only applies to the rows/columns that contain ? clues. It probably should say R4c9 is 3 and R4c8 is 6 then r4c7 = 1 and R4c4 is 9.

Q: Does the indexing rule count for all rows and columns or just for the clued ones? example row 3 would suggest the second option.
Thanks Rocky
