Logic Masters Deutschland e.V.

Normal Sudoku rules apply.
Draw a German whisper line and a renban line into the grid, starting and ending in the grey cells. One line moves orthogonally from cell to cell while the other moves diagonally. Lines do not cross, branch or share cells.

Clues outside the grid indicate the total number of cells in the row or column that appear on a line.

Adjacent digits on the German whisper differ by 5 or more. The renban contains a set of consecutive digits in any order. Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio
