Dual Windoku
(Published on 4. February 2020, 11:49 by Feadoor)
A leftover from my recent Sudoku GP round. This puzzle was replaced with an easier one to have more balance. There are two puzzles in one grid:
- Windoku - standard Sudoku rules, and also 1-9 exactly once in each shaded region
- Anti-Windoku - standard Sudoku rules, and also each shaded region contains exactly four different digits
Solution code: Row 7, Column 5 (Windoku), Row 7, Column 5 (Anti-Windoku)

@Ragna,
die vier Reihen bzw. Spalten in der Reihenfolge wie es da steht, also insgesamt 36 Ziffern.

Thank you. I assumed by mistake, that every digit has to appear at least two times.

@Rollo
Each column, each row, each outlined 3x3-box exactly nine digits and
shaded regions exactly four digits.

I am puzzled a little bit by 'Anti-Windoku - standard Sudoku rules', because it is not possible in this case. So does it mean 'Every row, every column, every 3x3-box and every shaded region contains exactly four different digits'?

I also liked the puzzles in the contest. Even the diagonal and anti-diagonal with the same set of clues.

Even without starting solving I say: Impressive, very impressive!
