For the Hanoi toy puzzle, this means alternating between the smallest piece and largest available piece (remembering that you can only take from the top of a stack of disks). This is a very basic solution using a repeated sequence of instructions until the puzzle is solved. There are three main methods for solving Towers of Hanoi puzzles in the fewest amount of moves: In this case, the “N” represents the amount of starting disks.
The minimum number of moves required to solve a Tower of Hanoi is 2 to the power of N minus 1 (2 n-1). If you’re interested in the math behind solving a Tower of Hanoi problem, it works like this. So, a 4-disk problem takes 15 moves, a 5-disk problem takes 31 moves, a 6-disk problem takes 63 moves and so on. Every time you add another starting disk, that minimum number of moves is doubled + 1. For example, in a 3-disk problem, you will have to use a minimum of 7 moves.

In fact, learning how to solve it can be easier than learning card tricks!Įach Tower of Hanoi problem has a minimum number of moves to solve it that is based on the amount of disks you start with. While the Tower of Hanoi is rooted in mathematics, you don’t need to understand or use complex math to solve it.

Who where The Doctor was forced to play a mind-numbing 1,023-move Tower of Hanoi puzzle called “The Trilogic Game” and in the 2011 blockbuster movie Rise of the Planet of the Apes where it was used as an intelligence test for the apes. The Tower of Hanoi has also had a prominent role in pop culture and video games. As that is approximately 42 times the current age of the universe, we should be safe for now.
If the legend were true, and the priests were also able to find a remarkably efficient way to move one disk per second, it would take an mind-boggling 585 billion years to complete the task. One of the best parts about mathematical puzzles is that we can easily calculate how long they would take to solve. However, there probably isn’t reason to panic just yet. It is believed that once the Tower of Brahma is complete, the world would end. Acting under Brahmin rule, the priests are continually moving the disks, one disk at a time. This temple houses a room with three massive pillars wrapped with 64 golden disks. The most popular one is the mystical theory that it is an homage to an ancient Indian temple in Kashi Vishwanath where Brahmin priests have been acting out an ancient prophecy since the beginning of history (this is where the name Tower of Brahma came from). Since the Tower of Hanoi puzzle was first introduced by French mathematician Édouard Lucas in 1883 (hence the name Lucas Tower), many myths about its origins have been shared. However, most toy versions come with anywhere from 5 to 9 disks. The Tower of Hanoi can be played with any number of disks. Each disk can be placed on any rod, but it cannot be placed on top of a smaller disk.You can only move the disk that is on top of a stack.However, while this seems simple at first, there are a few rules that make this classic puzzle game such a favorite among puzzlers and math teachers alike: The object of the Tower of Hanoi puzzle is to move all the disks from the left rod to the right rod. This creates the iconic cylinder or pyramid shape that the Tower of Hanoi is known for. The Towers of Hanoi, also called Tower of Brahma, Lucas’ Tower, or more simply, the pyramid puzzle, is a mathematical game using three rods and various numbers of colored disks stacked in descending order with the larger disk on the bottom and the smaller disks stacked on top. While you might not immediately recognize the name, many of you will probably recognize the Tower of Hanoi as soon as you see it. However, one logic problem that truly unites everyone from puzzle lovers to math geeks is the Tower of Hanoi. In fact, mathematical concepts are the core theme behind many of our favorites games, puzzles and riddles such as tic-tac-toe, chess, sudoku and nonograms. Puzzles and mathematics have always shared a harmonious relationship.
