Logic Masters Deutschland e.V.

Rules:

Sudoku: Normal sudoku rules apply. The digits 1-9 appear once in each row, column, and 3x3 box.

Lines: The central, given 7 has 7 lines emanating from it. Blue lines are divided by regions into segments of the same sums. Not all blue lines need to have the same sums. Green lines have adjacent digits with differences of at least five. Orange lines have adjacent digits with differences of at least four. Purple lines contain digits from a non-repeating set of consecutive digits, arranged in any order.

Kropki: Two regions contain two gray dots each. In each of these regions, one gray dot is black and one gray dot is white. The solver must determine dot colors. White dots separate consecutive digits. Black dots separate digits in a 2:1 ratio.
