The goal of the game is to move the disks around in such a way that three new towers are formed, each consisting of disks of the same color. As in the standard version of the Towers of Hanoi game, you are allowed to move only one disk at a time, and you are not allowed to place a larger disk on top of smaller one, no matter what the color.

Once you've decided which disk you want to move, click on that disk. Then select a destination tower to move the disk to that tower. If you try to move a disk on top of a smaller disk, you will receive an error message. You can, however, move a disk on top of a disk of the same size. You can play the game beginning with any number of towers between 2 and 7. We suggest starting at 2 and proceeding upwards. You can change the initial number of disks using the slider at the right. The goal is to reconstruct the Tower in as few moves as possible. You should see a pattern in the minimum number of moves as you increase the number of disks. The number of moves you make is recorded below the Towers. You may start again by clicking on the Reset button. Have fun.
