How is Castles in Spain different from Baker's Dozen?

Same deal, three different rules. Castles in Spain builds down in alternating colors (Baker's Dozen ignores suit and color), an empty pile accepts any card (Baker's Dozen spaces stay empty forever), and the Kings are left wherever they are dealt (Baker's Dozen sinks them to the bottom of their piles). The color rule makes each move tighter; the open spaces give the flexibility back.

Can I move groups of cards?

No. Only one card at a time, and only the top card of a pile. Even a perfect red-black run has to be carried one card per move. That single-card rule is what makes an open, fully visible deal genuinely hard.

What can I put on an empty pile?

Any single card — an Ace, a King, anything in between. Empty piles work like free cells: park a blocking card there to reach what it covered. Because they take anything, opening a pile is almost always worth the moves it costs.

Are all Castles in Spain deals winnable?

Most deals can be won with careful play, but not all — a deal can bury the aces beyond reach no matter what you do. Everything is visible from the first move, so a loss is at least an honest one: the information was all there.

Where does the name come from?

"Building castles in Spain" is an old idiom for daydreaming — the same idea as castles in the air. The game has carried the name since the classic patience anthologies; it has no special connection to Spain itself.

How Do You Play Castles in Spain?

Goal: build all four foundations from Ace to King by suit.

Setup

Tableau: 13 piles of four cards each (52 cards), all face-up.
Foundations: four empty piles. Build up by suit, Ace to King.
No stock, no waste, no reserves.

Rules

Build tableau piles down in alternating colors: a red 7 goes on a black 8, a black 7 on a red 8.
Move one card at a time. No group moves.
An empty pile accepts any card — not just Kings.
Foundations build up by suit, Ace to King. Cards on a foundation stay there.

What's the Best Castles in Spain Strategy?

Send Aces and 2s up immediately. They start the foundations and free the cards above them.
Treat empty piles as free cells. A space takes any card, so an emptied pile is the most powerful resource on the board.
Plan around the color rule. Each card has at most two hosts on the whole board. Check that a landing spot exists before you dig.
Don't bury your hosts. Dropping a card on the only black 8 in view can strand every red 7 in the game.
Hold middle cards back. 5s through 9s are the hosts your tableau runs on; banking them too early strands the cards above.

A Short History

Castles in Spain is a classic member of the Baker's Dozen family, recorded in the classic anthologies. The name is the old idiom for a daydream — "building castles in Spain." Older books dealt part of each pile face down; modern digital versions, this one included, deal every card face up, which turns the game into a pure planning puzzle.
