About Tower of Hanoi

Solve the Tower of Hanoi puzzle online. Move the entire stack of disks from one rod to another, following specific rules. A classic mathematical puzzle to test your problem-solving skills.

How to Play

Move all disks from the leftmost rod to the rightmost rod. You can only move one disk at a time, and no disk may be placed on top of a smaller disk.

Tips & Strategies

  • For an odd number of disks, make the first move from the source to the destination rod.
  • For an even number of disks, make the first move from the source to the auxiliary rod.
  • Never place a larger disk on top of a smaller one.
  • Try to develop a pattern or algorithm to solve the puzzle efficiently.
  • The minimum number of moves required is 2^n - 1, where n is the number of disks.

Fun Facts

  • The Tower of Hanoi puzzle was invented by the French mathematician Édouard Lucas in 1883.
  • There's a legend that says monks in a temple are solving a Tower of Hanoi puzzle with 64 disks. When they finish, the world will end!
  • With 64 disks, it would take 2^64 - 1 moves (over 18 quintillion) to solve the puzzle.
  • If you could make one move per second, it would take over 580 billion years to complete the 64-disk puzzle.
