Solitaire is a classic single-player card game that involves organizing a shuffled deck of cards into a specific order using strategy, logic, and patience. Although there are many variations, the most widely known version is Klondike Solitaire, made famous by its inclusion in early versions of Microsoft Windows. With its calm pace and rewarding problem-solving, Solitaire has become one of the most recognized and enduring card games in the world.

In the traditional Klondike version, the game begins with seven piles of cards arranged in increasing length from left to right. Only the top card of each pile is face-up; the rest are face-down. The remaining cards form a stock pile that the player draws from during the game. The objective is to build four foundation piles, one for each suit, in ascending order from Ace to King.

Gameplay revolves around moving cards between tableaux by following alternating colors and descending order. For example, you may place a red 7 on a black 8. When a face-down card becomes uncovered, it is flipped over, giving the player new possibilities for moves. Empty tableau spaces can only be filled with a King (or a pile starting with one), creating strategic moments where clearing a pile becomes important.

Players must decide when to draw from the stock, when to hold cards for future moves, and when to commit to a particular sequence. Success often requires planning several moves ahead, making Solitaire a blend of luck and skill. Each round is a puzzle where the player works to uncover cards efficiently, preserve flexibility, and reach the foundations before running out of moves.

Solitaire’s popularity comes from its accessibility, relaxing pace, and sense of quiet challenge. It can be played with a physical deck of cards or digitally, where additional features—like hints, undo buttons, and different draw settings—enhance the experience. Whether played casually or with a focus on strategy, Solitaire remains a timeless, meditative game enjoyed by millions.
