Logic Masters Deutschland e.V.

A simple puzzle combining some of my favourite genres in an approachable way. Enjoy!

Rules:

Sudoku: Place the digits 1-9 exactly once in each row, column and box.

German Whisper Coral: Shade some cells of the grid. The shaded cells form a single orthogonally connected region, and all unshaded cells are orthogonally connected to the edge of the grid. There cannot be a 2x2 of shaded cells. Digits in edge-adjacent shaded cells must differ by at least 5.

Japanese Sums: Clues outside the grid indicate the sums of contiguous segments of shaded cells in that row or column. There must be at least one unshaded cell seperating two segments. All such sums are given and in the correct order. ?s stand for any digit 0-9, but leading zeros are not allowed.
