Beleaguered Castle — often searched simply as Castle Solitaire — is a single-deck game of pure skill. The four Aces begin already placed on the foundations, and the remaining 48 cards are dealt face-up into eight columns, so nothing is hidden and nothing is left to luck. Your task is to free the cards in the right order and build all four suits up from Ace to King. With every card in plain sight, success depends entirely on planning and sequencing — making this one of the most satisfying open-information solitaire games to master. This free online Castle Solitaire plays instantly in your browser — no download and no sign-up.
What Is Castle Solitaire (Beleaguered Castle)?
Beleaguered Castle is a classic patience game played with a single 52-card deck. It belongs to the same family as Streets and Alleys and Fortress, all of which arrange their columns around the four foundation piles like the walls of a besieged fortress — the image that gives the game its name. The defining feature is that the four Aces are removed at the start and placed directly onto the foundations, giving every game a guaranteed head start.
Because all 48 tableau cards are dealt face-up, Beleaguered Castle contains no hidden information and no shuffling luck once the deal is set. Every deal is a self-contained puzzle: the cards you can see are the only cards you have, and whether you win depends solely on the order in which you unpack them. This makes Castle Solitaire a favorite among players who prefer a logical challenge over the chance-driven swings of Klondike.
This free online version follows the standard rules. Build the tableau down by rank regardless of suit, move one card at a time, and send cards up to the foundations by suit. Play in your browser on desktop, tablet, or phone — with no download, no sign-up, and unlimited undo to help you learn.
How to Play Castle Solitaire — Complete Rules
Setup and Deal
The four Aces are lifted from the deck and placed face-up on the four foundation piles. The remaining 48 cards are dealt face-up into eight tableau columns of six cards each, arranged in two banks of four columns to the left and right of the foundations. There is no stock pile and no waste pile — every card is on the table from the first move.
Objective
Build each of the four foundations up in suit from Ace to King. The game is won when all 52 cards — the four Aces already placed plus the 48 in the tableau — have been moved to the foundations in order.
Rules of Play
- Only the rightmost, exposed card of each tableau column may be moved.
- Build down in the tableau by rank, regardless of suit — for example, place any 9 on any 10.
- Move exactly one card at a time; sequences cannot be moved as a group.
- Send cards up to the foundations by suit in ascending order: 2, 3, 4, and so on up to King.
- An empty column may be filled by any single available card, which makes empty columns valuable workspace.
- There is no stock and no redeal — when no useful moves remain, the deal is lost.
Beleaguered Castle Strategy Guide
1. Look Before You Move
Because every card is face-up, you can and should plan several moves ahead before touching anything. Scan all eight columns and trace where each low card you need is buried. The temptation to make an obvious move immediately is the most common way to lose; a move that feels productive can permanently bury a card you will need a few turns later. Treat each deal as a puzzle to be solved in your head first.
2. Free the Low Cards Early
Your immediate goal is to release the 2s and 3s so the foundations can start climbing. Identify which columns hold the deuces and work to expose them without trapping other key cards beneath long descending runs. Advancing all four suits a little at a time is usually safer than racing one suit far ahead, because balanced foundations give the tableau more places to unload cards.
3. Guard Your Empty Columns
An empty column is the most powerful resource in Beleaguered Castle. Since any card may be placed into an empty column, it acts as temporary storage that lets you dig out a buried card or rearrange a stubborn run. Do not fill an empty column casually — hold it open until you have a specific plan, and try to re-empty it whenever you can. Running out of empty space with cards still tangled is how most winnable-looking deals slip away.
4. Build Long Descending Runs Carefully
Because you can build down regardless of suit, it is easy to assemble long descending sequences — but remember you can only move one card at a time. A long run is only useful if you can dismantle it card by card when the moment comes. Before stacking cards into a deep run, make sure you will have somewhere to put them later, or you may create a column you can never take apart.
Is Beleaguered Castle Winnable?
Beleaguered Castle is one of the more winnable open-information games. Studies of computer solvers put the proportion of solvable deals at roughly 75%, meaning about three out of four games can be won with perfect play. Because there is no hidden information, the gap between a deal being solvable and a player actually winning it is entirely down to skill: with careful planning and disciplined use of empty columns, dedicated players can win a large share of the deals they are given.
| Castle-Family Game | Aces Start | Empty Column | Approx. Solvable |
|---|---|---|---|
| Beleaguered Castle | On foundations | Any card fills | ~75% |
| Streets and Alleys | In the tableau | Any card fills | ~65% |
| Fortress | In the tableau | Any card fills | ~25–35% |
| Citadel | On foundations | Filled during deal | ~80% |
The pre-placed Aces are what make Beleaguered Castle friendlier than its close relative Streets and Alleys, where you must dig the Aces out of the tableau yourself before the foundations can even begin. If you enjoy Castle Solitaire and want a sterner test, Streets and Alleys is the natural next step.
Castle Solitaire vs. Streets and Alleys vs. Forty Thieves
These single-deck patience games are often grouped together, but they play very differently:
| Feature | Beleaguered Castle | Streets and Alleys | Forty Thieves |
|---|---|---|---|
| Decks | 1 | 1 | 2 |
| Cards hidden | None | None | None |
| Aces pre-placed | Yes | No | No |
| Tableau building | Down, any suit | Down, any suit | Down, same suit |
| Difficulty | Intermediate | Hard | Very hard |
A Short History of Beleaguered Castle
Beleaguered Castle is an old patience game whose layout — two flanks of columns pressing in on a central row of foundations — evokes a fortress under siege, which is where the name comes from. It appears in 19th- and early 20th-century collections of solitaire games under names such as Laying Siege and Sham Battle, and it has remained popular ever since precisely because it removes luck almost entirely. In an age of flashy, animated card games, the appeal of Beleaguered Castle endures for the same reason it always has: it is a clean, honest puzzle that rewards thought.
Common Mistakes to Avoid
- Making the first available move without scanning all eight columns for a better plan.
- Burying a needed low card under a long descending run you cannot easily take apart.
- Filling an empty column too early, before you have a clear use for the space.
- Racing one suit far ahead and stranding mid-rank cards the tableau still needs.
- Forgetting that cards move one at a time, and planning as if you could move whole sequences.
Tips for Beginners
If you are new to Castle Solitaire, start slowly and use the unlimited undo to experiment. Pick one deal and try to free all four 2s before doing anything else, so you can see how the foundations begin to climb. Keep at least one column empty whenever possible, and resist the urge to build a single giant run. Do not worry about winning every game — even with about three in four deals being solvable, perfect play takes practice. Focus on reading the whole board before each move, and your win rate will climb steadily.

Frequently Asked Questions
What is Castle Solitaire?
Castle Solitaire is another name for Beleaguered Castle, a single-deck patience game in which the four Aces start on the foundations and the other 48 cards are dealt face-up into eight columns. You build the tableau down by rank regardless of suit and send cards up to the foundations by suit, with no hidden cards and no luck once the deal is set.
Is Beleaguered Castle a game of skill or luck?
It is almost entirely skill. Every card is visible from the start, so there is no hidden information and no drawing from a stock. Once the deal is laid out, whether you win depends purely on the order in which you unpack the cards, making it one of the most skill-based solitaire games.
What percentage of Beleaguered Castle games can be won?
Computer analysis suggests roughly 75% of deals are solvable with perfect play. Because there is no luck, your actual win rate is a direct reflection of your skill, and it improves steadily as you learn to plan ahead and protect empty columns.
How is Beleaguered Castle different from Streets and Alleys?
The games are nearly identical except for one rule: in Beleaguered Castle the four Aces start on the foundations, while in Streets and Alleys you must free the Aces from the tableau yourself. That head start makes Beleaguered Castle noticeably easier and more winnable.
Can you move more than one card at a time?
No. In Beleaguered Castle you move exactly one card at a time — only the exposed end card of each column. You cannot move a built sequence as a group, which is why planning how you will later dismantle a long run matters so much.

No. This Castle Solitaire plays directly in your web browser with nothing to download or install and no sign-up required. It works on desktop, tablet, and mobile, and includes unlimited undo.
