- How do I play Tower of Hanoi?
- Move all disks to peg C — larger disks can't go on smaller ones The game is completely free and runs directly in your browser — no plugins or downloads needed.
- What's the minimum number of moves needed?
- For N disks the minimum is 2^N - 1 moves. For example, 3 disks need 7 moves, 5 disks need 31, and 7 disks need 127. The number of moves grows exponentially with the number of disks — that's what makes Tower of Hanoi a classic algorithmic problem.
- Is there a general solution? How should I think about it?
- The core idea is recursion: to move N disks, first move the top N-1 disks to the middle peg (using the target peg as a helper), then move the largest disk to the target peg, and finally move the N-1 disks from the middle peg to the target. Break it down step by step this way.
- How many levels or difficulty tiers does Tower of Hanoi offer?
- Typically three tiers (easy, medium, hard), plus procedurally generated puzzles in some cases. Even replaying the same difficulty can produce a completely different layout.
- What can I do in Tower of Hanoi if I get completely stuck?
- An undo or reset button is built in. Tower of Hanoi encourages experimenting, so taking a step back is always an option without penalty.
