Anti-Sudoku
(Eingestellt am 21. Juni 2021, 14:02 Uhr von HawkAvatar)
Normal Sudoku rules do NOT apply.
Each row, column and box has exactly 1 digit repeated twice (equivalently 1 missing digit).
Furthermore, no two rows share a repeat digit nor a missing digit (e.g. if row 1 has 2 2s and 0 9s, then no other row may have more than one 2, and all other rows must have at least one 9). Similarly for columns and boxes.
A web interface for checking a filled anti-sudoku grid is available on github
Lösungscode: Extra digits in rows 1-9 followed by missing digits in columns 1-9

Great work! I was drawn to this one cause I've actually attempted this concept a few times myself, only I used the digit 0, so if you're interested, you can check my first 3 puzzles -- I named that variant 'Doppelganger', but in fact, I learned that the setter Richard had ALSO came up with something similar, which he called 'Blackout'
