Day 23: Santa's sleigh ride!
(Published on 23. December 2025, 06:00 by SharpFox)
Only one day until Christmas! Time for another Special.
Rules:
- Normal 6×6 Sudoku rules apply.
- Red Kropki dots with the christmas tree join digits, where one is double the other. A gray circle indicates an odd digit.
- Put the harness on Rudolph! Draw a red line from the sleigh to rudolph to harness him. This line is one-cell wide and only moves orthogonally. This harness may not pass through any cells, that are filled with a gray circle or part of a red Kropki dot. In addition it doesn't pass any thick ice barriers.
- Collect the lost gifts! The harness must go through the cells with a present. The harness doesn't branch or cross itself.
- Summation rule: In every set of three adjacent cells along the red line, there are two, that must sum to the third one.
- Santa's sleigh contains the digit 2.
Solution code: Row 1 (6 digits):

Cool puzzle, though it seems to have an anti king restriction that shouldn't be there, and makes it so some digits are always marked as errors

Took a little bit to get started, but proceeded quickly and smoothly after the first few digits.
Looking forward to the final few puzzles of the Advent Calendar.
