This puzzle might be the most famous movement game of all time!
The task is to transfer the stack of 9 disks from the centre post to one of the outer posts, never allowing a disk to sit on top of a disk that’s smaller than itself.
It looks quite doable. But you’ll soon realise the enormity of the challenge when you understand there are no less than 255 moves to achieve this. And that answer has never been a shortcut!
There are many myths and legends about the origins of this puzzle but it seems that the French Mathematician Edouard Lucas actually created the puzzle in 1883. He may have also created the essence of the myths as well to help promote the puzzle and give it an air of mystique.
The most common legend is that of the temple of Benares, where the centre of the world was, there was a brass plate on which stood 3 diamond needles. While creating the world God placed 64 gold disks on them. This is the Tower of Hanoi. The priest is set the task of moving the disks from one needle to another and it’s said that once they are all moved the world will end with a big bang. With 64 disks the number of moves would end up being 18,446,744,073,709,551,615. It’s been theorised that if every move took one second it would still take nearly 6 billion centuries to complete! Seems it will be a while yet before the end of the world.
And lucky our puzzle only has 9 disks and so 255 moves assuming you don’t make any mistakes along the way. With persistence, you will see a pattern emerging and work out how to do the puzzle.
