Klondike Solitaire

It is played with one deck of 52 cards. The goal of the game is to arrange the cards by suit in order from ace to king in four piles (they are sometimes called basic, or "houses"). The card can be shifted to another higher rank, but of a different color (black or red). In each of the four basic piles (houses), according to which all the cards must be laid out, aces are first placed, then twos, threes, and so on to the king. Cards can be dealt from the deck remaining from the distribution (in the upper left corner) either one or three pieces, depending on the modification. Only the king can be placed in a free cell (not a house). The game ends when all the cards are laid out.
