Logic Masters Deutschland e.V.

Normal sudoku rules apply.
Regional Constraints: For each clue type, there may be no repeated digits on that type. E.g. the 9 cells on renbans contain 9 different digits.
Tentropy Line (TEN): On the long line, every run of 4 cells contains one digit from each of the groups {1,9}, {2,8}, {3,7} and {4,6}. 5 never appears on the line.
Renban Lines (REN): For each 3-cell line, its digits form a consecutive run (like 234) when sorted.
German Whisper Lines (GW): For each 2-cell line, its digits differ by 5 or more.
Kropki Pairs: Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio. Not all dots are necessarily given.
