Tower of Hanoi — The Classic Mathematical Puzzle Game

Tower of Hanoi is a free browser puzzle game based on one of the most elegant mathematical challenges ever devised. Three pegs, a stack of colourful disks, and one deceptively simple rule — can you move the entire stack from one peg to another without ever placing a larger disk on top of a smaller one?

How It Works

The game starts with up to seven disks stacked in pyramid order on the leftmost peg — largest at the bottom, smallest on top. Your goal is to move the entire stack to the rightmost peg. The rules are strict: you can only move one disk at a time, and you can never place a larger disk on top of a smaller one. Click a peg to lift its top disk, then click a destination peg to place it.

The minimum number of moves needed is shown upfront — for 7 disks that is 127. Every move is counted in real time, and when you finish the game celebrates with “Solved with X moves!” The challenge is not just to solve it, but to solve it in as few moves as possible.

Key Features

• 1 to 7 configurable disks — adjust difficulty with + and − buttons before each game
• Live move counter — tracks every move made against the theoretical minimum
• Minimum moves displayed — know exactly how optimal your solution needs to be
• Invalid move warning — a red toast notification slides up if you break the rules
• Multilingual support — auto-detects English, Spanish, French, and Portuguese
• Warm, playful visual design — colorful disks on mauve-purple rods, soft cream background
• Play Again with confirmation — reset safely without accidentally losing progress
• Free to play — runs in any browser, no download or account needed

Who Is It For?

Tower of Hanoi is for puzzle lovers, students, and curious minds of all ages. It is a staple of computer science education — the puzzle perfectly illustrates recursive thinking and exponential complexity — but it is equally enjoyable as a pure logic challenge. Younger players can start with 3 or 4 disks, while experienced puzzlers can push for a perfect 7-disk solution.

If you enjoy brain teasers, logic puzzles, or classic mathematical games, Tower of Hanoi is a timeless challenge that never gets old.
