Feel free to first try Doppelgangers or Counterclockwise Killer for practice with the ruleset. Enjoy and please leave a comment!
Rules:
Rules:
- Doppelganger (with an extra twist): Place the digits 0-9 in the 9x9 grid (one digit per cell) so that each row, column, and box is missing one digit from 1-9. Digits may not repeat in any row, column, or box. Digit 0 appears 9 times, and the remaining digits appear 8 times each. For each 0 in the grid, the digit missing in that 0's row and column must be different. Furthermore, the digits missing in a 0's respective row or column must both appear in the bottom right 2x2 corner of that 0's box.
- 1/9 Indexing: If cell (x,y) contains digit 1, then cell (x,1) contains digit y and cell (1,y) contains digit x. If cell (x,y) contains digit 9, then cell (x,9) contains digit y and cell (9,y) contains digit x.
- Each digit on a red line must appear on the other red line.
Lösungscode: Row 4 of the 9x9 grid (left to right) followed by Column 4 of the 9x9 grid (top to bottom).

Two question about the rules:
1. "Furthermore, a digit missing in a 0's row or column must appear in (here's the extra twist) the bottom right 2x2 corner of that 0's box." Do you mean both digits or at least one?
2.The coordinate (x,y) indicates row x column y?
----------------
1. Both missing digits must appear in the bottom right 2x2 of the 0's box. I'll update the rules for clarity.
2. Yes (x,y) is row x column y.
