MoYu Hanoi Tower 8 Layers is a physical take on the classic Tower of Hanoi puzzle.

You move stacked discs between pegs one at a time, and a larger disc can never rest on a smaller one.

With eight layers the shortest possible solution runs 255 moves, so clearing it is a genuine project rather than a coffee break toy.

The six layer version keeps things gentler, while the ten layer build pushes far past this one in length.
