How to play +

The small things matter.

Move all discs from the left peg to the right peg. Move only the top disc, one at a time. A larger disc can never rest on a smaller disc.

Controls & hints

Tap or click a source tower, then its destination. Keys 1, 2, 3 do the same. Press U to undo. Tap the selected peg again to cancel.

Undo removes a move from your count. A hint is calculated from your current position, even after a detour. The minimum shown is for a fresh start: 2ⁿ − 1.

First strategy

Free the largest disc by building the smaller tower on the middle peg. Then move the largest disc right.
