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 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.
