The Key / Der Schlüssel
(Published on 5. November 2025, 21:37 by Caterpillar)
This is the first Sudoku I ever set, so I hope it’ll be at least somewhat enjoyable. I will be uploading more sudokus, hopefully each better than the last. In any case, enjoy!
Rules
Standard 9x9 sudoku rules apply.
The key is a german whisper line, neighbouring digits along this line must differ by at least 5.
The keyhole is a thermometer, digits on it must increase from the bulb end.
The white kropki dot stands between consecutive digits.
Digits along the diagonals, which are indicated outside the grid, sum to the given numbers.
Along one of the two main diagonals, three odd digits appear twice and along the other diagonal, three even digits appear twice (for clarity: the remaining 3 digits along either diagonal may be either odd or even, but appear only once).
Digits on the two small diagonals in box 1 and 3 sum to the same even number.
Digits on the two small diagonals in box 7 and 9 sum to the same odd number.
Solution code: Row 1
