Blacken some of the fields in the diagram and put digits from 1 to 7 into the other fields, so that no number appears more than once in every row or column. The numbers at the borders give the sum of consecutive digits (without black fields in between) in the correct order. Single digits are also given. In some columns the hints are completely missing. In all other rows and columns they are completely given.
Lösungscode: column 2 and column 3. Use S for black field.
