Tower of Hanoi
Move the stack to the last peg one disc at a time, across four levels up to 8 discs in a perfect 255 moves.
Select a peg to lift its top disc.
How to play
- Move the whole stack to the right-hand peg, one disc at a time, never placing a larger disc on a smaller one.
- Click or tap a peg (or press 1, 2, 3) to lift its top disc, then choose where to drop it.
- The minimum for n discs is 2ⁿ − 1 moves. Easy: 3 discs. Hard: 5. Extreme: 7 discs within minimum + 20%. Nightmare: 8 discs in exactly 255 moves — one wasted move loses.
