Logic Masters Deutschland e.V.

Rules:

Normal suducku rules apply. Place digits from 1-9 into each cell without repeating in a row, column, or 3x3 box.

Draw paths between the ducks such that each duck is connected to exactly one other duck. (Each duck is the start or end point of a path.) The paths travel orthogonally between the centers of cells and do not branch. In addition, the paths act as duck whisper lines; adjacent digits on each path must differ by 4 or more.

The digit in the blossom of a sumflower is the sum of the digits on its stem.

Box borders divide the pond into groups of cells with the same sum.

Digits separated by a bee sum to 5; not all bees are given.
