Beleaguered Castle is a single-deck patience with a striking layout: the four Aces sit in a column down the centre as the foundation starters, and eight tableau columns of six cards each spread out from them — four to the left, four to the right. All 48 tableau cards are face-up from the start. There are no free cells, no stock, no reserve. You build the tableau down regardless of suit, but only one card at a time.

Goal: build all four foundations from Ace to King by suit.
Both have full open information. The difference is whether you have any reserve space.
| Aspect | FreeCell | Beleaguered Castle |
|---|---|---|
| Tableau columns | 8 | 8 |
| Free cells / reserves | 4 | 0 |
| Foundations at start | Empty | Seeded with Aces |
| Tableau building | Down by alternating color | Down regardless of suit |
| Group moves | Yes (with empty cells/columns) | One card at a time only |
| Practical win rate (skilled) | ~99.9% | Much lower — most deals are solvable in theory, far fewer are won in practice |
The seeded Aces and build-anywhere rule are the easier parts of Beleaguered Castle. The lack of reserves and the strict single-card move are what give it real difficulty. Players coming from FreeCell often miss the four free cells immediately.
Beleaguered Castle is a 19th-century single-deck patience, also published under the names Laying Siege and Sham Battle. The military theme reflects the visual layout — Aces in a centre column with tableau "forces" spread out flanking them. The game is a fixture of the standard patience literature — Albert Morehead and Geoffrey Mott-Smith's Complete Book of Solitaire and Patience Games (1949) and David Parlett's Penguin Book of Patience (1979) both describe it under this name — and it lends its name to the whole "castle" family of open packers, including Streets and Alleys and Fortress. It has remained niche but well-known among patience scholars for the elegant centre-out layout.
