Tower of Hanoi

Game Description
The Tower of Hanoi is a timeless logic and problem-solving puzzle. This version consists of a single-piece base with three fixed pegs and five removable rings of increasing diameter.
All five rings start stacked on one peg, with the largest at the bottom and the smallest at the top. The challenge is to move the entire stack to another peg while following a simple set of rules. Despite its minimal design, the puzzle encourages strategic thinking, patience, and planning.
This model is designed specifically for easy 3D printing in PLA with no supports required.

Game Components
1 one-piece base with 3 vertical pegs
5 rings (graduated sizes)

No assembly is required after printing.

Rules of the Game
Only one ring may be moved at a time.
A ring may only be placed on top of a larger ring or on an empty peg.
Rings must be moved directly between pegs—no holding or stacking off the board.
The goal is to move all five rings from the starting peg to a different peg.

Objective
Move all five rings from the starting peg to a target peg using the remaining peg as a helper, while obeying the rules.

Challenge Level
Minimum number of moves required to solve the puzzle: 31 moves

Try to complete the puzzle in the fewest moves possible for an added challenge.
