Logic Masters Deutschland e.V.

inspired by RobertBe's puzzle from 2013 here.

Blacken two cells in each row, column and 3x3 block, with the normal Hitori restrictions:

- black cells cannot touch one another orthogonally

- all white cells must be orthogonally connected to each other to form one single area

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.
