Place digits 1-7 in the grid so that no digit is repeated within a row/column. Numbers in the diagram indicate the difference between the biggest and smallest digit in the visible cells. A digit can see others until its view is blocked with a black cell. If there is only one cell in sight, the number indicates the digit itself. No cell may remain empty.
Solution code: column 3 and column 4 (12 numbers)

Also, for clarification: You need to put a number in every empty cell. When the rules say 'black cell' they mean the grey cells.

@Anna: Danke! Dann suche ich mal nach einem anderen Denkfehler ;-))

@flaemmchen: "black cells" sind nur die vorgegebenen grauen Felder. Und es werden auch keine weiteren zugefügt.

Wieder mal Verständigungs-Probleme: "black cells" sind die grauen mit den Ziffern (oder auch ohne), oder kann man auch noch Schwarzfelder hinzufügen???
Vielen Dank vorab!
