House of CardsVerified

House of Cards fundamentally rewrites the rules of the traditional Solitaire genre by completely abandoning the familiar mechanics of foundation building and tableau sorting in favor of a highly complex, architectural puzzle based entirely on structural mathematics. Set against a clean, visually uncluttered green felt aesthetic, players are presented with a deck of cards and a completely empty workspace. Your objective is intensely focused and heavily reliant on sequence planning: you must physically drag cards from the deck to construct a multi-tiered pyramid (a house of cards). The challenge lies in the strict engineering rules: to build a higher floor, the foundation "walls" beneath it must be mathematically sound. A wall consists of two cards leaning against each other. They MUST be a pair of the same value or the same suit. The atmosphere is deeply cerebral and immensely satisfying; you are essentially managing a massive game of localized arithmetic while simultaneously preventing your structure from collapsing under its own weight. The visual presentation is highly functional, utilizing crisp, high-contrast traditional playing cards.

How to Play

• The primary objective is to build the highest, most structurally sound house of cards possible before running out of valid moves.
• Use your Mouse to click and drag cards from the draw pile onto the empty felt.
• Building Walls: You must construct walls by pairing two cards. These two cards MUST match in either VALUE (e.g., two 8s) or SUIT (e.g., two Hearts).
• Building Roofs: Once two adjacent walls are constructed, you can place a "Roof" horizontally across them. A roof can be ANY card; there are no restrictions on roof cards.
• Building the Next Floor: Once you have a valid roof, you can begin building the next set of walls on top of it.
• The Weight Limit: The total numerical value of the walls on a higher floor CANNOT exceed the total numerical value of the walls supporting them directly beneath. Face cards have specific high values (J=11, Q=12, K=13).

Tips and Tricks

• Build a Massive Foundation: Do not try to build vertically too quickly. The wider your ground floor is, the more options you have for building the second floor. A narrow base will restrict your options and force a game over quickly.
• Save the High Values for the Bottom: Because higher floors cannot outweigh the floors beneath them, you MUST use your highest value pairs (like Kings, Queens, and 10s) as the structural foundation on the very bottom row. If you put a pair of 2s on the bottom row, you can never build above them.
• Use Low Cards for Roofs: Roofs have no restrictions and do not count toward the weight limit. Therefore, you should always use your lowest, most useless cards (like Aces, 2s, and 3s that don't match anything) as the horizontal roofs.
• The Magic 20/21: The game notes that walls with a total value of 20 or 21 have special capabilities (usually acting as unbreakable supports that ignore weight limits). Memorize the combinations that create these numbers (e.g., a King + 7, or two 10s) and prioritize building them.
• Don't Waste Pairs: If you draw two 8s, DO NOT use one of them as a roof. Pairs are incredibly hard to come by, and you absolutely need them to construct valid walls.
