Canfield Solitaire

Canfield Solitaire is a classic variant where the foundation base rank is determined randomly. Thirteen cards are dealt to a reserve pile (only the top card is playable), one card is placed on the first foundation to set the base rank, and four cards are dealt to four tableau columns. The remaining cards form the stock, drawn three at a time. Build foundations up by suit from the base rank, wrapping from King to Ace if needed. For example, if the base rank is 7, build 7-8-9-10-J-Q-K-A-2-3-4-5-6. Tableau columns build down in alternating colors, also wrapping. When a tableau column is empty, it's automatically filled from the reserve. The game is won when all four foundations contain 13 cards.

• Pay close attention to the base rank — it determines the entire strategy for building foundations.
• Try to empty the reserve pile as quickly as possible, since cards from the reserve will automatically move to fill any empty tableau spaces.
• Go through the stock pile multiple times to find useful cards you may have missed.
• Build tableau columns strategically to create longer sequences that can be moved together.
• Keep track of which cards are buried in the stock — knowing what's coming helps plan moves ahead.

Solitaire originated in Northern Europe in the late 18th century, likely in Germany or Scandinavia. It was originally called 'Patience.' The Klondike variant became widely popular during the Gold Rush era in the late 1800s and reached mainstream audiences when Microsoft included it in Windows 3.0 in 1990.
