Klondike is a solitaire card game often known purely by the name of Solitaire. It is probably the most well known solo card game.
To win solitaire you must get all the cards onto the foundation piles. Each foundation has one suit and the cards must be placed in order, starting with aces.
The game is played with a single pack of 52 playing cards. After thoroughly shuffling the deck, 28 cards are dealt face down to form the tableau which consists of 7 columns of 1,2,3,4,5,6 and 7 overlapping cards from left to right respectively. The exposed card at the end of each tableau column is turned face up.
