Canfield is a single-deck patience invented as a casino game by Richard A. Canfield around 1900. Four tableau columns of one card each, a 13-card reserve, and four foundations — but the foundation rank isn't always Ace. The first card dealt to a foundation sets the starting rank for all four. From there you build up by suit, wrapping past King back to Ace if needed. The 13-card reserve and three-card stock draw create a tight, distinctive puzzle. Free in your browser, no sign-up.

Goal: build all four foundations up by suit (with wrap) until each contains 13 cards.
Both build by alternating color, but the layouts and stock rules differ in three ways that matter.
| Aspect | Klondike | Canfield |
|---|---|---|
| Tableau columns | 7 (1–7 cards) | 4 (1 card each) |
| Reserve | None | 13 cards (top visible) |
| Foundation start | Always Ace | Random — set by first dealt card |
| Empty column fill | King only | Auto from reserve, then any card |
| Stock recycle | Unlimited (varies) | Unlimited |
| Solver: winnable deals | about 90% Draw 1, about 82% Draw 3 | about 71% (Blake & Gent, 2026) |
Canfield was invented by Richard A. Canfield, a New York gambler and casino owner, around 1900. He sold the game at his casino in Saratoga Springs: players bought a deck and were paid a fixed sum for every card sent to the foundations — a deliberately punishing house edge. The game is also called Demon in British patience traditions, predating Canfield's commercial version. Microsoft included Canfield in some early Windows solitaire packages but never made it a headline title.

The first card dealt to a foundation sets the starting rank for all four. If it's a 7, the foundations go 7-8-9-10-J-Q-K-A-2-3-4-5-6 (with wrap). This is Canfield's defining quirk — it varies the puzzle across deals more than a fixed Ace start would, and it forces you to plan with the wrap in mind.
The reserve is a 13-card stack to the side. Only the top card is visible and playable. As you remove top cards from the reserve, the next one flips up. While the reserve has cards, empty tableau columns auto-fill from it. Once the reserve empties, any card or group can fill an empty column.
No. A solver that can see every card wins about 71% of Canfield deals (Blake & Gent, 2026); people, who cannot see the reserve or stock, win far fewer. The 13-card reserve and three-card stock draw produce tight positions, so Canfield is one of the harder common solitaire variants.
Three things: Canfield has only four tableau columns (Klondike has seven), a 13-card reserve (Klondike has none), and a random foundation start rank (Klondike always starts at Ace). Both build by alternating colors, but Canfield wraps King back to Ace in both the foundation and the tableau.
Richard A. Canfield, a New York gambler and casino owner, invented the game around 1900. He sold it at his casino in Saratoga Springs as a paid bet — players bought a deck and won a fixed sum per card sent to the foundations. The payouts were set so the house kept a substantial edge. The variant is also called Demon in British patience traditions, predating Canfield's commercial version.
