Calculation is a classic card game with a simple design that lets you focus entirely on the gameplay without distractions. Calculation (also known as Broken Intervals) is a type of solitaire. While luck plays a large role, it also requires strategic thinking. At first, it may feel difficult, but as you get used to it, your chances of winning improve—making it a deeply engaging game. The game uses a standard deck of 52 cards (excluding Jokers), and suits are not considered. Once placed, a card cannot be moved to another pile, so planning ahead is essential. The goal is to build each sequence up to the King, following the designated order. Solitaire refers to card games designed for a single player, and Calculation is one of them. Despite its simple rules, it offers a unique balance of luck and strategy that keeps the game both challenging and rewarding.
