Sudoku & Hitori
(Published on 26. August 2013, 19:01 by RobertBe)
- black cells cannot touch one another horizontally or vertically. Diagonally is allowed.
- all white cells must be in one area. The black cells may not divide the white area in two parts.
Place the numbers 1-7 in the white cells so that every row, column and 3x3 block contains these numbers exactly once in the white cells. Place the numbers 1-6 in the black cells so that every row and column of 3x3 blocks contains these numbers exactly once in the black cells.
To clarify: Row 1-3 form the first row of 3x3 blocks, rows 4-6 the second row, Rows 7-9 the third row. Same rule for columns.
Solution code: Row 1, followed by Column 8 (18 numbers)

Once the 3x3-rule was explained another way it was loud and clear to me... Liked it Robert, thank you!!

Thanks Rainer for an excellent clarification. I thought that my original wording was obvious, but apparently you can interpret it in another way :(

Clarification added due to comments about rows and columns of 3x3 blocks

@Rainer: Danke für die Erklärung. Das hatte ich ganz anders verstanden.(Hab mich aber nicht getraut zu fragen).

Ich hoffe mal, dass man die verdeckte Frage von ch1983 beantworten darf.
Die erste Zeile/Spalte von 3x3 Blöcken besteht aus den Zeilen/Spalten 1 bis 3. Die zweite Reihe/Spalte von 3x3 Blöcken besteht aus den Zeilen 4-6 und die dritte Reihe/Spalte aus den Zeilen/Spalten 7-9.
Es gibt also 3 Zeilen/Spalten von 3x3 Blöcken im Gitter.

Sehr schöne Kombination. Die Idee, die Zahlen in den Schwarzfeldern in die Sudokuregeln einzubeziehen, ist prima.

Interessante Sudoku-Variante, in die man sich erst hineindenken muss.
