RULE SET:
Normal Sudoku rules apply. Place the digits 1 through 9 in each row, column, and box.
RENBAN (PURPLE): Digits along a purple Renban line must be a set of consecutive non-repeating digits, and may appear in any order.
GERMAN WHISPER (GREEN): Adjacent digits along a green German Whispers line must differ by at least 5. Digits may repeat if other rules allow.
DUTCH WHISPER (ORANGE): Adjacent digits along the orange Dutch Whispers line must differ by at least 4. Digits may repeat if other rules allow.
KROPKI: Cells separated by a black dot are a 1:2 ratio. Cells separated by a white dot are consecutive. Not all dots are given.
DIAMONDS (RED and BLACK):
The set of three red diamonds sum to 19.
(R3C9 + R4C3 + R7C7 = 19)
The set of three black diamonds sum to 16.
(R1C9 + R3C3 + R8C4 = 16)
For our color blind friends:
Renban (3 total): R3C9-R4C7, and lines in boxes 4 and 9.
German whisper (3 total): Lines in boxes 1, 2 and bottom of box 6.
Dutch whisper (3 total): Lines in boxes 3, 5 and 7.
