The Weird E-key
(Published on 6. August 2025, 22:07 by ebiggie)
RULE SET:
Normal Sudoku rules apply. Place the digits 1 through 9 in each row, column, and box.
X-pairs. Cells separated by a "X" must sum to 10. There is a negative constraint for X-pairs in this puzzle.
-----> ALL X-Pairs ARE GIVEN <-----
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.
DIAMONDS (RED): The set of four red diamonds sum to 18.
(R2C1 + R3C5 + R3C9 + R9C8 = 18)
For our color blind friends:
German Whisper lines are thick, Renban lines are thin.
