Logic Masters Deutschland e.V.

RULE SET:

Normal Sudoku rules apply. Place the digits 1 through 9 in each row, column, and box.

ANTI-KNIGHT: Cells separated by a knight’s move in chess cannot have the same digit.

KILLER CAGES: The sum of the cells in a cage must equal the total given for that cage. Digits in a cage do not repeat.

GERMAN WHISPER (GREEN): Adjacent digits along a green German Whispers line must differ by at least 5. Digits may repeat if other rules allow.

RENBAN (PURPLE): Digits along a purple Renban line must be a set of consecutive non-repeating digits, and may appear in any order.

For our color blind friends:
German whisper lines are thick, Renban lines are thin.
