This is a holiday version of the classic “Towers of Hanoi” game.
The rules are the same: the goal is to move your tree from the left trunk to the right trunk, and you can only stack small discs (or branches, in this case) on top of larger ones, never upside down. The middle trunk serves as an intermediate storage area as you move branches back and forth between trunks.
If you have a multi-color printer, you could print the trunks brown and the base in some other color, such as red.
The author marked this model as their own original creation.
