X-ray Sums
(Eingestellt am 21. Februar 2025, 19:39 Uhr von MonsieurTRISTE)
Rules:
1. Normal sudoku rules apply. Fill the grid with digits from 1 to 9 so that no digits repeat in any row, column, or box.
2. A clue outside the grid gives the sum of all digits N that is placed in the Nth position on the row/column (if the clue doesn't have an arrow) or the indicated diagonal (if the clue has an arrow). For example, a row 325694781 would have 2+7+8=17 for the left clue and 1+4+6=11 for the right clue.
3. The clues are encoded with letters and question marks. Every letter represents a unique digit from 0 to 9. A number with 2 digits can't start with 0. A question mark stands for any positive number (possibly greater than 9 … !).
Lösungscode: Digits in column A, top to bottom. Here “A” takes its value in the puzzle.

Finally it dawned on me which column to enter. Nice opening. Definitely tougher ending. :-) Thanks

Nice idea, quite tricky to figure out and some difficult sudoku (for me) towards the end! I'd reword the "?" rule to say, it stands for any digit from 1 to 9.

Thanks for solving! It still works if “?” stands for any positive integer, possibly greater than 9. Rewording so makes it slightly easier to solve.

Ah OK, I misunderstood then, I relied on that in my solve!

kann ein einzelner Buchstabe 0 bedeuten?

Letters that only occur in clues with one digit can be zero or positive.
