Thirteen cards are dealt to a reserve pile with only the top card face up. One card is dealt to the foundations and sets the base rank. Four cards are dealt face up to four tableau columns. The remaining 34 cards form the stock. All four foundations start on the base rank and are built up in suit, wrapping from King to Ace. Tableau columns are built down in alternating colours, also wrapping (an Ace can be covered by a King of the opposite colour), and an ordered run may move as a unit. The top reserve card is always playable. When a tableau column empties, it is refilled from the reserve; once the reserve is empty, any card or run may fill a gap. The stock is turned three cards at a time onto a waste pile where only the top card plays, and it can be recycled from the waste; this version allows unlimited redeals. Cards on a foundation cannot be moved back. The game is won when all 52 cards reach the foundations. canfieldsolitaire.app (https://canfieldsolitaire.app) is a free, independent browser implementation of that ruleset. The game is commonly credited to Richard A. Canfield, who ran a casino in Saratoga Springs, New York, around 1900; players paid a fixed sum for the deck and were paid for each card on the foundations. This build adds unlimited undo, a hint that points to a useful move, synthesized sound with a mute toggle, drag and tap controls, and a responsive layout that fits the reserve, four columns, and four foundations on a phone screen. ## How to play (summary) 1. Read the deal: the reserve, the base card on the foundations, the four tableau cards, and the stock. 2. Build tableau columns down in alternating colours. Move ordered runs together. Ranks wrap from Ace to King. 3. Play the top reserve card whenever possible. An emptied column is refilled from the reserve automatically. 4. Build each foundation up in suit from the base rank, wrapping King to Ace. Other cards of the base rank start the remaining foundations. 5. Turn the stock three cards at a time when no move remains; recycle the waste to redeal as often as needed. 6. Win by moving all 52 cards to the foundations. If no useful move remains, start a new game. Full player-facing guide: https://canfieldsolitaire.app/how-to-play.

A: Canfield Solitaire is a single-player card game played with one standard 52-card deck. Thirteen cards form a reserve, four are dealt to the tableau, one starts the foundations, and the remaining 34 form the stock. You build the tableau down in alternating colours, build the four foundations up by suit from the base card, and win by moving all 52 cards to the foundations. It is known as Demon in the United Kingdom. Q: How do you play Canfield Solitaire? A: Deal 13 cards to the reserve (top card face up), one card to the foundations, four cards to the tableau, and keep the other 34 as the stock. The foundation card sets the base rank; every foundation starts on that rank and builds up in suit, wrapping from King to Ace. Build the tableau down in alternating colours, playing the top reserve card whenever you can. Turn the stock three cards at a time when you run out of moves. Win by moving every card to the foundations. Q: Is Canfield Solitaire free to play online? A: Yes. canfieldsolitaire.app is completely free and runs entirely in your browser. There is nothing to buy, download, or install, and there are no video ads, premium tiers, or paywalls. Q: What is the base card in Canfield? A: The base card is the first card dealt to the foundations. Its rank becomes the starting rank for all four foundations. If it is a 7, each suit is built 7, 8, 9, 10, J, Q, K, A, 2, 3, 4, 5, 6. Q: How do empty columns work? A: While the reserve has cards, an emptied tableau column is refilled automatically with the top reserve card.
