Castle Solitaire is played with a single standard 52-card deck and offers a clean, strategic challenge for fans of puzzle-style card games. The goal is simple: move all 52 cards onto the four foundations, building each one upward in suit from Ace to King.
Only the top card of each column is available to play at any time, so planning ahead is essential. That card can go either onto a foundation or onto another column, giving you meaningful choices at every turn.
Columns can be built either up or down, regardless of suit, which gives you plenty of flexibility when rearranging the layout. Whenever a column becomes completely empty, you can fill it with any card, opening up new ways to untangle the board and work toward a complete win.
