The tableau is the main playing area, the columns of cards dealt at the start. The foundations are the four piles you build up by suit from Ace to King to win. The stock is the face-down pile of cards left over after the deal, and the waste is where cards from the stock land face up. Most other solitaire words describe what you do with those four.
The words are old. People played patience with real cards for well over a century before computers, and the rule books, from Lady Cadogan's in the 1870s to David Parlett's The Penguin Book of Patience (1979), settled on a shared set of terms. Some come from French: tableau is French for a picture, and talon, an older word for the stock, is French for "heel".
Even the game's name depends on where you live. Americans say solitaire, the British say patience, and both mean the same family of one-player card games. Wikipedia keeps a glossary of patience terms with the sources for each word; the list below covers the ones you meet when you play online.
| Term | What it is | Also called | Where you see it |
|---|---|---|---|
| Tableau | The columns dealt at the start, where you move cards around | Layout, columns, piles | Nearly every game |
| Foundation | A pile built up in one suit from Ace to King; filling all of them wins | Home cell | Klondike, FreeCell |
| Stock | The face-down cards left after the deal, turned up during play | Talon, draw pile | Klondike, Spider, Pyramid, TriPeaks |
| Waste | The face-up pile where stock cards are turned; its top card can be played | Talon, discard pile, waste pile | Klondike, Pyramid, TriPeaks |
| Free cell | A space that holds one card at a time | Cell | FreeCell |
| Cascade | One of the overlapping columns of the tableau | Column, pile | FreeCell |
One word is used both ways. Some books call the stock the talon; others use talon for the waste. If a set of rules says "talon", check which pile it means.
In Klondike, the classic game that came with Windows, the tableau is seven columns holding 28 cards, with only the last card of each column face up at the start. In FreeCell it is eight columns with every card face up. Most games build down the tableau, each card one rank lower than the one it goes on, often in alternating colors.
Each foundation starts with an Ace and grows one rank at a time in the same suit. In Klondike and FreeCell there are four; in Spider, which uses two decks, finished runs from King to Ace leave the table instead, and you win when all eight are gone.
The stock is the part of the deck you have not seen yet. In Klondike you turn cards from it onto the waste, one at a time in Turn 1 or three at a time in Turn 3, and when the stock runs out you turn the waste over to make a new stock. That is called a redeal. In Spider there is no waste: each deal from the stock puts one card on every column.
The tableau is the set of columns dealt face up or partly face down at the start of the game. It is where most of the play happens: you move cards between its columns to uncover the ones you need.
A foundation is a pile you build from Ace to King in one suit. Klondike and FreeCell have four. Getting all 52 cards onto them wins the game.
The stock is face down and holds the cards you haven't seen. The waste is the face-up pile where those cards go when you turn them, and only its top card can be played.
Yes. Patience is the usual British name and solitaire the American one for the same family of one-player card games. Klondike, the game most people mean by "solitaire", is often called just "Patience" in Britain.
An older word for the stock, the cards left over after the deal. Some rule books use it for the waste pile instead.
