Logic Masters Deutschland e.V.

Rules:

Place digits from 1 to 9 into some cells such that no digit repeats in a row or column. Clues outside the grid indicate the sums of connected groups of digits in the respective row or column, in order, where empty cells serve as delimeters between groups.

For every clued row or column, two different sets are provided.
One set of clues is incorrect in such a way that each clue is off by one, but otherwise it's the correct amount of clues in the right order.
The other set of clues is incorrect in some arbitrary way, meaning that one or more of the following must be true: the order and/or amount of clues is wrong, or at least one clue shows an incorrect sum.
For each row and column, the solver must determine which set is which.
