Solitaire is a popular single-player card game where the goal is to play cards in a specific order to achieve the highest possible score. The game includes various variations of irra solitaire (Klondike, Solitaire, Spider and others), but the principle of the game remains basically the same.

The player is given a pack of standard playing cards, which are shuffled and placed in several columns (open and closed) or on a special playing board. The player's goal is to transfer all cards in a given order to free cells or main piles in a certain suit and order of card value (usually from Ace to King). However, it is permissible to move cards between columns and piles, but subject to certain rules and restrictions.

Playing Solitaire requires logical thinking, strategic planning and attentiveness. Although some variations may have random elements, success in the game mainly depends on the ability to calculate possible moves and make the right decisions. Solitaire is a great way to pass time and develop mental skills.
