History and Origin of Calculation Solitaire
Calculation Solitaire has a long pedigree among card games, dating back to the 19th century. It likely originated in France, where the game is charmingly known as “La Plus Belle” (which means “the most beautiful”). The game belongs to the old Sir Tommy family of patience (solitaire) games – a group of early solitaire games popular in Europe. Nobody knows exactly who invented it; like many classic solitaires, it simply emerged in the 1800s and gained popularity over time. As the game spread, it picked up several alternate names. In English, Calculation has been called “Broken Intervals,” “Hopscotch,” and “Four Kings Solitaire,” among others. These nicknames hint at the game’s unique gameplay – “Hopscotch” alludes to the way you skip through card sequences, and “Four Kings” refers to the goal of ultimately filling four piles up to the King. No matter the name, players for generations have loved the clever, math-like build-up of cards that Calculation Solitaire offers.
Rules and How to Play Calculation Solitaire
Don’t be intimidated by the name – Calculation Solitaire is easy to learn once you understand the core concept of its “calculating” sequences. The game uses a standard 52-card deck and is played by yourself (like all solitaire games). The objective is to build four foundation piles from low cards up to Kings following specific numerical patterns. Here’s a step-by-step guide on how to play:
Setup the Foundations: Remove one Ace, one 2, one 3, and one 4 from the deck and place them face-up as the starting foundation cards (suits don’t matter in Calculation). These four cards are the bases of your four foundation piles. Each foundation will grow in a different increment: the Ace pile builds in steps of +1 (Ace, 2, 3, 4, and so on in normal order), the “2” pile builds in steps of +2 (2, 4, 6, 8, etc.), the “3” pile in steps of +3, and the “4” pile in steps of +4. In other words, for each foundation you “skip ahead” by 1, 2, 3, or 4 ranks at a time. Eventually, each foundation should reach a King as the final card. (For example, the 2-pile would progress 2, 4, 6, 8, 10, Q, A, 3, 5, 7, 9, J, K in a full cycle.)
Prepare the Stock: Shuffle the remaining 48 cards and keep them face-down in a pile, which will serve as the stock (draw pile). There is no traditional tableau in Calculation Solitaire; instead, you will draw from the stock and use up to four temporary holding piles (called waste piles) during play.
Draw and Play Cards: Turn over the top card of the stock one at a time. For each card you draw, determine if it can be played onto one of the foundation piles. A card can be played on a foundation if it is the next card needed in that foundation’s numerical sequence. For example, if you draw a 2 and your Ace-foundation is showing an Ace on top, you can place the 2 there (since the Ace pile builds by 1s). If you draw a 6 and your “4” foundation currently has a 4 on top, you can place the 6 there (since the 4 pile builds by 4s: 4 then 8, then Q, etc., so 6 is the next in sequence after 4 in that cycle). Whenever a drawn card fits the next number for any foundation, play it immediately onto that foundation.
Use Waste Piles for Unplayable Cards: If a drawn card cannot be placed on any foundation yet, don’t worry – you have up to four waste piles (also called tableau piles in this game) to help. Place the card face-up into one of the waste pile spots. You can start a waste pile with any card, and there’s no strict building order or suit requirement on these piles. Essentially, waste piles are just holding areas for cards until they become playable to the foundations. However, only the top card of each waste pile is accessible – you can only move the top card from a waste pile to a foundation, and you cannot move cards between waste piles or back to the stock. Use the waste piles wisely to store cards that are waiting for their turn to be played.
Continue Drawing and Playing: Keep revealing cards from the stock one by one, playing each card either to a foundation (if it fits the sequence) or to a waste pile (if it doesn’t fit yet). At any time, if the top card of a waste pile becomes the exact card needed to continue a foundation, you may move that waste card up to its foundation. There’s no limit to moving waste cards onto foundations whenever they become playable – in fact, that’s key to winning the game. The process continues until you have gone through the entire stock.
Winning the Game: You win when all 52 cards have been successfully placed onto the four foundation piles in their correct sequences up to Kings. If you run out of moves (stock is exhausted and no waste pile tops can play) and the foundations are not complete, then the game is lost. But don’t be discouraged – with strategy and a bit of luck in the shuffle, you can often clear all the cards. The challenge of Calculation Solitaire is figuring out the right order to play cards so that eventually every card finds its home on a foundation pile.
A typical starting layout for Calculation Solitaire. Four foundations begin with Ace, 2, 3, 4 as base cards, and the remaining deck becomes the face-down stock. As cards are drawn, they are either placed on the appropriate foundation (if they continue the sequence) or set aside into one of four waste piles (not shown here) until needed. The goal is to build each foundation up to a King to win the game.
Understanding the sequences: One of the defining features of Calculation Solitaire is that suits don’t matter at all – only the card ranks (numbers) matter in building the foundations. This is why the game is described as “numbers-based.” Each foundation follows a looping arithmetic sequence (adding 1, 2, 3, or 4 each time). It may seem confusing at first, but you’ll quickly get the hang of it. Essentially, you’re performing a modular arithmetic on the ranks: after King, the sequence wraps around to Ace and continues. The different increment on each pile means you have to calculate and anticipate which cards will be needed next for each foundation. This is the puzzle-like aspect that makes the game so engaging.
Once you understand the setup and sequences, playing Calculation Solitaire becomes a fun exercise in planning and foresight. Every card will eventually belong on one of the four foundations; your task is to figure out the order to uncover and place them. Next, let’s look at some tips and tricks that can help you improve your strategy and win more often.
Tips and Tricks for Improving Your Gameplay
While Calculation Solitaire has a straightforward premise, winning consistently takes strategy. Here are some helpful tips and tricks to boost your success rate and make the game more enjoyable:
Play cards to the foundations as soon as possible: Don’t hesitate when you have a valid move. If a card in the stock or on top of a waste pile can go onto a foundation, play it immediately. Holding back a playable card often just ends up burying it under other cards in the waste, making it harder to access later. By playing it right away, you keep the foundations moving and create space for other cards.
Organize your waste piles wisely: Since you can have up to four waste piles, use them with a plan. A common strategy is to dedicate one waste pile just for Kings (and perhaps other “late game” cards like Jacks and 10s). Kings are the highest cards needed last in every sequence, so any King you draw will sit for a long time before it can be played. Parking all your Kings in one pile keeps them out of the way and prevents them from blocking lower cards in other piles. Also, try to keep waste piles somewhat organized so you can always see the bottom card of each pile – it gives you insight into what cards will be freed up next when the top moves.
Remember that suits don’t matter: In Calculation Solitaire, ignore the suits (hearts, clubs, diamonds, spades) completely. You can place any suit on any foundation as long as the number is correct in the sequence. This means you should focus purely on the numerical order of cards. Don’t waste time worrying about color or suit matches – planning your moves by number is the key.
Plan your sequences and “jumps”: Pay attention to which cards will be coming up in each foundation’s sequence and plan accordingly. For example, cards like 6, 8, and Queen often appear mid-sequence and can be played earlier in the game without issue, whereas 10s, Jacks, and Kings create larger jumps in the sequence and typically can’t be placed until very late. If you draw a 10 or Jack early, you might tuck it away in a waste pile and try to play other cards first. By using the smaller interval cards (like 6s or 8s) when you can, you keep progress going on multiple foundations and delay the toughest cards until you have no other moves. This strategic pacing of cards will prevent premature dead-ends.
Stay patient and practice: Calculation Solitaire is known for offering more scope for skill than many other solitaire games. The good news is that as you practice, you’ll get much better at spotting the sequences and managing the waste piles. In fact, a skilled player can win up to 80% of their games, whereas casual play might only win around 20–30%. That’s a huge difference that comes down to strategy! So don’t be discouraged if you lose a few rounds at first. Every deal of Calculation is actually winnable with the right strategy – it’s a matter of learning from mistakes and recognizing patterns. Keep playing, and you’ll soon find yourself winning far more often as your skill improves.
Interesting Facts and Trivia About Calculation Solitaire
Calculation Solitaire has some fascinating aspects that set it apart from other card games. Here are a few fun facts and bits of trivia to appreciate:
What’s in a name? The French name for this game, La Plus Belle, literally means “the most beautiful”. Early players apparently held this solitaire in high regard! Meanwhile, one of its old English names, Hopscotch, hints at the gameplay – much like the children’s game Hopscotch, you “hop” through numbers in fixed intervals when building the foundation sequences.
Skill vs. luck – a game of strategy: Calculation is often praised for its emphasis on skill. It offers far more control than luck-based solitaire variants. In fact, statistics suggest that a beginner might win only about 1 in 5 games, but an expert can win more than 4 out of 5 games. That stark contrast shows how much planning and strategy influence the outcome. If you enjoy a solitaire game where your decisions truly matter, Calculation is one to try.
Every deal can be beaten (theoretically): Some enthusiasts claim that every single game of Calculation Solitaire is winnable with perfect play. That means, unlike some solitaire games that depend on the shuffle, here there’s no such thing as an “unwinnable” deal – you just have to figure out the right sequence of moves. Whether this is 100% true is up for debate, but it’s an encouraging thought that keeps players coming back – if you didn’t win, you might find a better strategy next time and crack the puzzle!
These unique qualities make Calculation Solitaire stand out in the solitaire family. It’s both a historical classic and a fresh challenge for modern players who love a good brain game.
