Towers of Hanoi is a classic puzzle comprising three poles and six different-sized discs, each with a hole at its centre. The discs are placed onto one pole, with the largest at the bottom, then the next largest, and so on, so that the smallest is at the top.


Playing

In this browser-based version you move a disc from one pole by pressing on the pole (or any of the discs on the pole). What happens then depends on the situation:

  • if the top disc can move to only one of the other poles, the system simply moves it onto that pole;
  • if the top disc can move onto either of the other poles, a question mark will be shown against each of these. You then need to tell the system which pole to move it onto by pressing on one of these.
  • if the top disc cannot move onto either of the other poles (because it is larger than the discs on these poles), then nothing happens.
The number of moves you have made is displayed above the New button. Try to keep the number of moves to a minimum. The minimum number of moves possible is 63.

New Game

Just press on the New button at any time to start a new game starting from the initial layout. This also resets the number of moves made back to zero.
