This guide teaches Klondike, the game most people mean by Solitaire, from your first look at the table to the end of the opening. You need no cards. Play Solitaire now in another tab and follow along.
You win when all 52 cards are on the foundations.
In the tableau, put a card on another card one rank higher and of the other color: a red 5 on a black 6. You can move a whole face-up run the same way, as long as its bottom card fits. Any Ace goes straight to an empty foundation, and the 2 of that suit follows it. When you uncover a face-down card, it turns face up. When you run out of moves, click the stock to draw. The complete rules cover the rest.
Drag a card or a run to move it. On a computer, double-click a card to send it to the best place it can go, usually a foundation. On a phone, a tap does the same. Click the stock to draw. When it is empty, click it again to turn the waste back into a new stock. Hint outlines a card and draws an arrow to where it can go. Undo has no limit. When the rest of a game needs no decisions, a Finish button plays it out.
Before you touch the stock, look at the seven face-up cards. Move any Ace to a foundation. Then look for cards that fit on each other. Each move that leaves a face-down card on top of a column turns it over, and that is progress. Only when the tableau has nothing left to do should you draw from the stock.
Say the face-up cards on columns one to seven are: 8♠, A♦, 9♥, 7♦, K♣, 3♠ and 6♣. Here is one way to play the opening.
After seven moves you have turned over six face-down cards and have not drawn from the stock once. Notice the order. The King went into the empty column only because it had cards under it. The long run moved last, onto a card that had just appeared. A real deal will look different, but the same questions work every time: which move turns over a card, and which move opens the way for the next one?
Go through the stock and play what you can. If a full pass gives you nothing, press Hint. If Hint has nothing either, the game tells you no useful move is left. You can undo back to an earlier choice and try another line, or start a new game. Not every deal can be won, so a loss is not always a mistake.
