Logic Masters Deutschland e.V.

Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.

Digits separated by a white dot must be consecutive. Digits separated by a black dot must be in a 2:1 ratio. Not all dots are necessarily given.

Adjacent digits on a green line must differ by at least 5.

Box borders separate blue lines into segments. Digits on each segment of the same line sum to the same value. Different lines may have different segment sums.
