Solitaire Win Rate Calculator 🃏

Not all Solitaire games are created equal. While FreeCell is famous for being nearly 100% winnable (only a handful of unsolvable deals exist out of millions), standard Klondike relies heavily on luck.

• FreeCell: 99.99% solvable. It's almost always a skill issue if you lose.
• Spider (1 Suit): Very easy, winnable 90%+ of the time.
• Spider (4 Suits): The ultimate challenge. Even experts only win ~30-40% of games.
• Klondike: About 80% of deals are solvable theoretically, but human limitations bring this down to 40-50%.
