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.
Renban 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 renban line: It consists of a set of consecutive, non-repeating digits in some order. Each line is at least two cells long. Lines from different arrows may overlap.
