In this version of Klondike solitaire, you draw 3 cards at once and try to get all the cards onto the four foundations at the top.
You do this by building them up by suit (hearts, diamonds, spades and clubs) starting with the Ace, then 2, 3, 4, 5 and so on up to the King.
The game begins with the cards layed out in seven column with 1 card in the left column, 2 cards in the next column, 3 in the next.
The top card in each column is turned face up with all the other cards face down.
The stack of cards in the top left corner is called the stock. This is where the remaining cards are placed face down.
Clicking the stockpile will turn over three cards. If you are able to use the top card, the next of the two remaing cards becomes available to play. If you can use that card then the last remaining card becomes available.
The goal of the game is to move all of the cards to the four foundation stacks in the top right corner.
