Is Every Game of Solitaire Solvable?
Solitaire, also known as Klondike Solitaire, is a popular card game that has been a part of many people’s daily routines for generations. The game is simple: remove all cards from the tableau by playing them in sequential order, with aces as the starting point, and placing them in the foundation pile. But here’s the question: can every game of Solitaire be solved? The answer is not quite.
Not Every Game Can Be Won
It all comes down to the random nature of the deck shuffle. The distribution of cards at the start of each game affects the outcome. Some games will be more favorable, allowing a player to quickly remove cards from the tableau, while others may be extremely challenging or even unwinnable. In fact, a 1960 study by Richard Kayton found that only 26.1% of Solitaire games are solvable, meaning it is possible to remove all cards from the tableau and foundation piles.
But What Does ‘Solvable’ Mean?
Solvable means that a given board configuration, or arrangement of cards, can be manipulated to achieve the final goal: removing all cards. However, solvable doesn’t always mean easy. There are degrees of difficulty, with some games being more straightforward and others more complex.
What makes a Solitaire game solvable? ** Factors that contribute to a solvable game**:
• Low card deck: Fewer high-number cards (>7) increases the chances of a win
• Few blocked tableau cards: Leaving fewer options reduces the number of potential moves
• Connected cards: Adjoining cards of the same suit can lead to a smoother resolution
• No stuck or isolated cards: Having flexible options increases the chances of winning
• Well-planned initial layout: The order and placement of the initial cards affects future moves
Facts that contradict solvability:
• Randomized shuffling: Each new game is unpredictable
• Limited moves: Forced moves, often due to blocked tableaus, restrict possibilities
• Unmoveable cards: Certain configurations, like immovable stacks, leave no alternatives
• Probability and statistics: Mathematically, a majority of games cannot be won
| Type of game | Outcome |
| Solvable | Mostly, with varying difficulties |
| Unsolvable | A random event may occur, precluding success |
Frequent Questions
Frequently Asked Questions (FAQs)
- Why do I get stuck with the same moves every time? Are the game settings rigged?
• The Solitaire game is **genuinely random**. What seems repetitive might be a subtle combination of game conditions, player approach, and randomness. - Are there ways to improve my Solitaire skills? **
• Practice makes better, but randomness will always retain a role.
• Focusing on developing strategic moves, tableau optimization, and probability awareness improves overall skills. - Are there alternative games of Solitaire? **
• Yes! Many variants (e.g., Spider Solitaire, Freecell Solitaire) have **more favorable** winning statistics. - I’m losing, is that normal?
• Expect losses due to randomness or incompatibility with optimal solvable combinations. - Why does my first game never take long? Is luck involved? **
• Yes! The initial shuffled deck heavily influences the outcome; luck and random factors still play a part. - Do all Solitaire games have different rules?

Conclusion: Can Every Game of Solitaire Be Solvable?
With an estimated 52 trillion possible configurations in Solitaire (2 to the power of 28), it is nearly impossible to develop an exhaustive guide or solution algorithm. Given the unpredictable outcomes and diverse difficulty levels, winning a Solitaire game becomes increasingly dependent on chance, making solvability only possible in the minority of games. However, the core mechanics remain intriguing, allowing both casual players and strategic enthusiasts to derive satisfaction and improve their skills within a realm governed by randomness.
