Logic Masters Deutschland e.V.

RULE SET:

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

ENTROPIC (GREY): Any set of three sequential cells along a grey line must contain a low digit (1,2,3), middle digit (4,5,6) and high digit (7,8,9).

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.

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.

Entropic lines (2 total): R4C1-R5C3, R7C6-R9C7.

German Whisper lines: (2 total): The "antenna" R1C3-R8C7, R8C2-R9C2.

Renban lines (4 total): the four remaining lines are Renban.
