Tower of Hanoi is a classic brain-game.
You have to move the whole tower to the stick on the right.
In the real world the discs have holes in them. But in this game just drag and drop them.

But behold! There are some rules....

1.) You can only move one disc at a time
2.) You can only move upper discs
3.) You can only place a smaller disc on a bigger one
