Tower of Hanoi 3D Puzzle Game

Tower of Hanoi is a logic puzzle where you move a stack of disks across three pegs, one disk at a time. The key rule is that a larger disk can never sit on a smaller disk, so each move requires planning, sequencing, and careful use of the spare peg.

How to Use This App

  • Select the number of disks you want to play with
  • Drag only the top disk from one peg to another peg
  • Place smaller disks on larger disks or empty pegs only
  • Use the spare peg to move disks in the correct order
  • Watch the move counter and timer as you solve the puzzle
  • Restart the game to try a different disk level or improve your result

Examples and Use Cases

Beginner practice: Choose 3 Disks to learn the basic Tower of Hanoi rule: move one disk at a time and never place a larger disk on a smaller disk.

  • Move-count challenge: Play a 4-disk game and try to finish with fewer moves on each attempt.
  • Timed puzzle session: Use the timer to see how quickly you can complete the tower without making invalid moves.
  • Strategy testing: Try 5 or 6 disks to practice planning several moves ahead using the middle peg as temporary storage.
  • Expert puzzle run: Select 7 or 8 disks for a harder challenge that requires patience, pattern recognition, and careful sequencing.

Helpful Details

Minimum Moves Formula

The fewest possible moves for Tower of Hanoi is 2^n - 1, where n is the number of disks. For example, 3 disks can be solved in 7 moves, 4 disks in 15 moves, and 8 disks in 255 moves.

Strategy Tips

  • Think recursively: Move the smaller stack out of the way, move the largest disk, then rebuild the smaller stack on top.
  • Use the middle peg carefully: Treat it as temporary storage, not a final destination.
  • Watch the smallest disk: Many solving patterns depend on moving the smallest disk in a regular direction.

Common Mistakes

  • Trying to move a disk that is not on top of its peg.
  • Dropping a larger disk onto a smaller disk.
  • Moving too quickly without planning where the largest remaining disk needs to go next.

Frequently Asked Questions

What is the goal of the Tower of Hanoi game?

The goal is to move all disks from the first peg to the last peg, one disk at a time, without placing a larger disk on top of a smaller disk.

How many disks can I play with?

The app lets you choose from 3 to 8 disks, so you can start with an easier puzzle and increase the difficulty as you improve.

What does the move counter show?

The move counter tracks how many valid disk moves you have made during the current game.

Can I restart the puzzle?

Yes. Use the restart button to reset the board, timer, and move counter for a new attempt.

What is the minimum number of moves needed?

The minimum number of moves is 2^n - 1, where n is the number of disks. For example, 3 disks require at least 7 moves.

Does the app include sound or theme options?

Yes. You can mute or unmute sound effects and switch between light and dark theme modes.
