Tower of Hanoi



Description The Tower of Hanoi was invented by French Mathematician Edouard Lucas in 1883. It is also referred to as "Tower of Brahma" or "End of the World Puzzle". This game is very challenging and requires lots of concentration. It is fun for anyone to play.

Educational Use The Tower of Hanoi is a fantastic educational game. It helps kids with problem solving skills, strategy skills, and recognizing patterns. If a child has played the game as well as possible, they should have discovered that the minimum number of moves it takes to win for 1,2,3,4 disks are 1,3,7,15. In order to find the number of moves for 4 disks, find a pattern relating the number of disks to the minimum number of moves it takes to win the game. Can you recognize a pattern. (Hint try adding one to each of the numbers) Recognize it now? Can you discover an equation to solve for n number of disks?

Can you fill in the rest of the table?

*Try using this equation 2^n-1=M where n=the number of disks and M=number of moves


How to Play The purpose of the game is to get the 3 disks stacked up on the right-most peg. However, two rules apply: you may only move one disk at a time and you may only place a disk on an empty peg or on top of a larger disk. You may not place a larger disk on a smaller disk. To move a disk, click on the disk you would like to move and drag it onto the peg you want.
