Tower of Hanoi

The Tower of Hanoi puzzle was invented by the French mathematician Edouard Lucas in 1883. We are given a tower of eight disks (four in the applet below), initially stacked in decreasing size on one of three pegs. The objective is to transfer the entire tower to one of the other pegs (the third one in the applet below), moving only one disk at a time and never a larger one onto a smaller.

This applet requires Sun's Java VM 2 which your browser may perceive as a popup. Which it is not. If you want to see the applet work, visit Sun's website at, download and install Java VM and enjoy the applet.

What if applet does not run?


The puzzle is isomorphic to an apparently different one.
