CALCULATION SOLITAIRE is a challenging game that will keep you thinking. Like normal solitaire the objective is to move all cards onto the foundation, but unlike normal solitaire you don't build the foundation in-order (suits are ignored). Rather you step by a number with wrap around (modulo 13 for the mathies in the crowd). The first pile is built stepping by 1s. A 2 3 4 5 6 7 8 8 T J Q K The second pile is built stepping by 2s. 2 4 6 8 T Q A 3 5 7 9 J K The third pile is built stepping by 3s. 3 6 9 Q 2 5 8 J A 4 7 T K The fourth pile is built stepping by 4s. 4 8 Q 3 7 J 2 6 T A 5 9 K Sounds confusing, but we provide a helpful hint card which shows the progression so you know what is coming next and can plan to win the game... which you will need to do because it is very challenging. There are board columns where you can stash cards that don't yet go on the foundations. However cards on the board cannot be moved, unless they are promoted to the foundation. Totally free!! No in-app purchases. You can play an easier or a harder version plus a bonus game One234 where all the cards are laid out in a fan. ## Key features - Unique foundation building by number steps - Hint card for planning - Stashing columns for cards - Adjustable difficulty levels - Bonus game mode ## Recent user reviews (4 of 4) All indexed reviews: https://appshunter.io/ios/app/calculation-solitaire/id938401085/reviews.md ### 3/5 — Deals are not varied properly *2024-05-09* If I play 5 times, 3 of the times will deal me a very similar pattern. not identical but say I will always get 3 5’s dealt within the first 15 or 20 cards . always. Same with others. The deal should be much more varied than it is. Defiantly a pattern, not a good one ### 2/5 — needs ad free version with more difficulty *2021-05-03* I like the no-nonsense format and simple layout, but would like room to try harder: all three variants of game are easy, and it's impossible to turn off hints. All this is ok for a relaxing game, but am deleting the app for one reason: obnoxious video ads. I'd rather use a paid app than have loud noise pop up unexpectedly. ### 5/5 — Addicting! *2015-08-15* Love this game! Spend too much time on it though. Once I start, it's hard to put down! ### 1/5 — No undo button *2015-07-27* No undo button, limited variations. ## Frequently asked questions about Calculation Solitaire ### What is Calculation Solitaire?
