There are two possible first moves in the Tower of Hanoi game. The smallest disks is on top of the stack. The largest disk is on the bottom, with the next largest disk above that, and so on. The disks are stacked there in a pyramid shape. The starting position for the disks is Pole A (the far left pole). I'll refer to the poles as Pole A, Pole B, and Pole C (left to right) from now on. To move a disk, drag the disk with your mouse from one pole to another. You cannot place a larger disk on top of a smaller disk. Move disks by sliding the disk off one pole and onto another. Disks can be moved according to the following rules: If you've never tried this puzzle before, leave it at the default 3 disks until you get the hang of it.Īs I mentioned, the object of Tower of Hanoi is to move all the disks from the left pole to the right pole. Select the number of disks you want to play with at the beginning of the game. The more disks, the more steps required to solve the puzzle. With this flash version of the Tower of Hanoi game, you can play using 3, 4, 5, or 6 disks at a time. There is a hole in the center of each disk, which allows you to slide the disk on and off the poles. The Tower of Hanoi game has only two parts:Ī set of 3 or more different-sized disks. It has even been used to test the mental function of brain injury patients.

This puzzle has appeared on TV shows like Survivor and in movies and books. Your local toy store probably has it, and you can find it online.Īlthough there are various styles of Tower of Hanoi puzzles, they all follow the same basic rules. You might want to pick up a set to have around the house or give as a gift. Tower of Hanoi was a physical puzzle long before it became a flash game. (See Tower of Hanoi Game - Instructions below for further explanation.) What makes this puzzle a challenge is that a larger disk cannot be placed on top of a smaller one. To solve the Tower of Hanoi game, you need to move the stacked disks one at a time from the far left pole to the far right pole. SPOILER ALERT: There is a pattern you can follow to easily solve Tower of Hanoi. Many people who've tried think it's impossible, especially when playing with 4 or more disks. Then you may find yourself quickly stumped. The minimal number of moves required to solve a Tower of Hanoi puzzle is 2 n − 1, where n is the number of disks.Tower of Hanoi appears simple until you start playing. Result(n,'A','C','B') // A, B and C are names of rods Result(n-1, auxiliary, destination, source) ("Move disk " + n + " from " + source + " to " + destination) // print the task Result(n-1, source, auxiliary, destination) ("Move disk 1 from " + source + " to " + destination) // print the task Static void result(long n, char source, char destination, char auxiliary)

Java Code for solving Tower of Hanoi Problem using 3 Disks Move n-1 disks from Auxiliary to destination rod.Move nth disk from source to destination rod.Move the top n-1 disks from source to Auxiliary rod.Java solution to maximize the chances of winning in Monty-Hall Paradox Problemĭemonstration using 3 Disks Algorithm to solve tower of Hanoi problem in Java:.FizzBuzz Problem In Java- A java code to solve FizzBuzz problem.We are not allowed to place a larger disk on a smaller one.We can not move more than one disk at a time.We have to move all disks from source rod to destination rod using auxiliary rod by following rules:. Source rod consists of ‘n’ disks in descending order of their sizes considering from the bottom where the smallest disk is at the top. In the puzzle, there are three rods suppose, left one is source rod, middle one Auxiliary rod, and right one destination rod. It consists of three rods and ‘n’ disks of different sizes which can slide onto any rod. The Tower of Hanoi is a Mathematical puzzle. We are going to solve it using recursive function calling approach. In this Java tutorial, we are going to discuss the famous Tower of Hanoi problem using ‘n’ disks.
