Logic Masters Deutschland e.V.

Rules: Normal Sudoku rules apply. Put the digits 1 to 6 once each into every row, column and 2x3 box.
German Whisper Arrows: A digit N in a cell with an arrow indicates that there is a straight line N cells long starting in the cell and extending in the direction of the arrow. This line acts as a German whisper line: Adjacent digits on the line differ by at least 3. Each line is at least 2 cells long. Any cells beyond the end of the line are not considered and can be any digit.
