Solitaire variant
Tower of Pisa Solitaire
A nine-card solitaire puzzle also known as Tower of Hanoy. Move one bottom card at a time and rebuild the full Ace-to-9 tower.
Move the bottom card of a column to the bottom of another column under a higher rank.
Pile 2
Pile 3
How this variant works
- Only the bottom card of a pile can move.
- Bottom-to-bottom moves must place a lower rank under a higher rank.
- If a pile is empty, you can move a bottom card from another pile to the top of the empty pile.
- Win by forming one complete Ace-to-9 tower in a single column.

Planning focus
The puzzle is tiny but tactical. A move that looks legal can lock rank order and remove your only path to the final single-column build.
Quick tips
- Treat every move as Tower-of-Hanoi planning: smaller ranks must stay beneath larger ranks at the bottom edge.
- Use empty-column moves to relocate blockers without destroying your strongest partial tower.
- Before moving an Ace or 2, check whether that card should stay reserved for a later full-stack finish.
