What is Klondike Solitaire?

Klondike Solitaire — simply called "Solitaire" by most — is the most played card game in history, largely because it was bundled with Microsoft Windows from 1990. Originally designed to teach users how to use a mouse, it became a cultural phenomenon and is estimated to have been played billions of times worldwide.

The game uses a standard 52-card deck and challenges the player to sort all cards into four foundation piles, organized by suit in ascending order from Ace to King.

💡 Pro Tips & Strategy

• Expose face-down cards first: Prioritize moves that reveal hidden cards over simply building sequences.
• Don't rush to the foundations: Sometimes keeping cards in the tableau gives you more flexibility for building sequences.
• Empty columns are gold: Work to create empty tableau columns — only Kings can go there, giving you powerful repositioning options.
• Move Aces immediately: Always move Aces (and often 2s) to foundations as soon as they appear.
• Think ahead: Before moving a sequence, consider what you'll need to place on it next.
• Alternate colors visually: Memorize red-black-red-black patterns to quickly spot valid moves.
• Don't cycle the stock randomly: Be intentional — draw from stock only when no tableau moves are available.
• Use undo strategically: Undo isn't cheating — professional players use it to explore decision trees.

📊 Did You Know?

Approximately 80% of Solitaire games are winnable with perfect play, though most players win around 43% of the time. The key variables are initial deal randomness and strategic decision-making. Some deal configurations are mathematically unwinnable regardless of skill — so don't be too hard on yourself!

The game was originally called "Patience" in Europe (particularly in the UK and Scandinavia), a name still commonly used today. The word reflects the game's core requirement: patient, methodical play over impulsive moves.
