How to Play Calculation Solitaire
Calculation solitaire is a slightly more challenging card game, but easy to learn and a whole lot of fun to play. Below is an outline of similarities and differences between the card games calculation solitaire and Klondike solitaire.
Like Klondike solitaire, the goal of the game is to get all cards into the four foundations in the upper-right hand corner. Beneath each foundation is a white box filled with numbers: all cards must be placed into the foundations in a particular order. Each box contains exactly 1 red number, which is the number of the card that that foundation will currently accept. When you place that card onto the foundation, the number in the box will advance.
Notice that the first foundation starts at Ace and counts upward by 1’s. The second starts with two, and counts by 2’s. The third starts with 3 and counts by 3’s. And so on.
In Klondike solitaire, cards in the tableau must be stacked atop opposing colors (red on black, vice-versa) in descending numerical order (three on four, queen on king, etc.)—but in Calculation Solitaire, you can stack cards in the in ANY order. Any card can be placed atop of any other card (i.e. you can place a king of spades on top of a 3 of clubs).
Additionally, you cannot continue to cycle through the deck once a card in the deck is face-up. You must first place the face-up card in the tableau. Once a card is placed into the tableau, you cannot move the card onto another spot in the tableau—you can only place it into the correct foundation slot.
Since each foundation accepts a King as its very last card, it’s generally good practice not to put a King atop of any other non-King cards. Try reserving one of the open spots in the tableau exclusively for King cards.
