(Published on 25. December 2025, 00:00 by koarla)
Normal Sudoku Rules: Place the digits 1 to 6 so that each digit appears exactly once in every row, every column, and every 2×3 box.
Branches: Diagonally adjacent digits on the green branches must differ by at least 3.
Trunk: The digits on the brown trunk form a set of consecutive numbers (e.g., 1-2-3-4-5), but they may appear in any order (e.g., 2-5-3-1-4).
Baubles: Digits separated by a red Christmas bauble have a 1:2 ratio. One digit must be exactly double the other.

Indeed nice puzzle, and indeed the solution checker appears to have the king's move rule

Nice puzzle. The solution checker confused me because it reacts to chess king rules that don't exist in the puzzle.
