    How to Play Beleaguered Castle

    There is no stock and nothing is hidden in Beleaguered Castle. Every card is on the table from the first move, so if you lose, it was the plan, not the luck of the draw.

    It has been described as FreeCell without the cells, and that is about right: all the same long-range thinking, with less room to work.

    Setup

    The four Aces start on the foundations. The other 48 cards are dealt face up into eight columns of six.

    Rules

    • Foundations build up in suit from Ace to King.
    • Columns build down one rank at a time, in any suit.
    • Only the bottom card of a column can move, and only one at a time.
    • Any single card can move to an empty column.
    • There is no stock. Every card is in play from the start.

    How to win

    Move all 52 cards to the foundations. Once the remaining cards can all go up in order, the autocomplete button finishes the game for you.

    How often can Beleaguered Castle be won?

    We ran our own solver on 200 shuffled deals of this version. It found a win in 26 of 200 (13%), showed that 60 could not be won, and ran out of its budget of 20,000 positions a deal on 114.

    Those undecided deals may still be winnable, so treat the win count as a minimum. The solver can see every card, including face-down ones, so it measures what the cards allow, not how often a person will win.

    Beleaguered Castle Strategy

    • Find your 2s first, since they are what the foundations need, then work out what you have to move to reach them.
    • Aim for one empty column early. It is the most powerful thing on the board, and it is what lets you shift short runs.
    • Build long runs carefully. With one-card moves you can't easily shift them later, so a long run sitting on a low card can be a dead end.
    • Plan several moves ahead and use Undo freely to test ideas. Since all the cards are visible, thinking it through really does pay.

    History

    First recorded in 1883. Other names include Laying Siege and Sham Battle.

    Beleaguered Castle FAQ

    Is every game of Beleaguered Castle winnable?

    No. One published study (Blake and Gent, 2019) put it at about 68% with perfect play. Our own search figure on this page is a lower bound from a limited search.

    What is the difference between Beleaguered Castle and Streets and Alleys?

    In Streets and Alleys the Aces are shuffled into the deck, so the first four columns hold seven cards and you have to dig the Aces out first.

    Why start with the Aces out?

    It is the traditional setup, and it gives you all four foundations to build on immediately.

    Do suits matter when building columns?

    No. Any 8 can go on any 9. Suits only matter on the foundations.
