How to play Tower of Hanoi
Move the whole tower of disks from the left peg to any other peg. Only one disk moves at a time, you may only take the top disk of a peg, and a disk may never sit on a smaller disk.
Controls
- Drag the top disk of a peg onto another peg (mouse or touch), or
- Tap a peg to lift its top disk, then tap the destination peg.
- Keyboard: press 1–4 to pick the source peg, then the destination peg. Esc cancels, U undoes.
Scoring
The minimum number of moves for n disks on 3 pegs is 2n − 1 (7 for 3 disks, 1023 for 10). With 4 pegs the puzzle is much shorter; the minimum shown uses the Frame–Stewart formula. Your best moves and best time for each disk count are saved.

Tip
On 3 pegs, the smallest disk moves every other turn, always cycling in the same direction. With an odd number of disks, move it first to the target peg; with an even number, to the spare peg.
