A nice classic puzzle game. Compact but playable.

Rules are simple: the object is to get the entire tower to a different peg. You may only move one disc at a time, You can never lay a wider disc on a narrower disc. Easy to learn. just start with 3 discs, then add more discs as you begin to understand the patterns.

I print with fuzzy skin, otherwise you get a bit of a corduroy effect when playing. Might be a feature or a bug, depending on your preference.

I haven't done it, but I suspect if you were to change your print settings so it prints by item and not by layer (you will probably have to spread over multiple prints), and used a rainbow filament you might get a pleasing gradient effect on the tower.
