Merry Grinch Day
(Published on 25. December 2024, 13:06 by ebiggie)
My wife created this puzzle. It's her first puzzle and wished it uploaded for Christmas. I only helped out with the technical bit. Happy Holidays! Enjoy.
RULE SET:
Normal Sudoku rules apply. Place the digits 1 through 9 in each row, column, and box.
ANTI-KING: Cells separated by a king’s move in chess cannot have the same digit.
ODD: Cells with a green circle (The Grinch's eyes) must contain an ODD digit.
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.
KROPKI DOTS: White dots are consecutive. Not all dots are given.
For our color blind friends:
The Grinch's scarf, R9C2 to R8C6, is Renban. All other lines are German whisper.

Solution code: Please provide the digits from row 8 (left to right):

Got stuck for a few minutes, cause I forgot the king move constraint. But overall pretty easy and very nice puzzle

This would have gone much faster if I had remembered the anti-king constraint! I solved all but one final disambiguation without using it and then stared and stared, wondering what I was missing.

modified ODD cell circle from "grey" to "green" to match color of the Grinch's eyes.
