Tower of Hanoi

Start with the core loop

Play Tower of Hanoi free online. Move the whole stack to another peg without placing a big disc on a small one, in minimum moves.

Select a source peg, then a destination. Keys 1-3 or arrows plus Enter are supported.

Build a better run

Choose three through seven discs and chase the mathematical minimum for every tower size.

Play with intent

Move the smallest disc every other turn. The parity of the tower determines the direction it should cycle.
