Solitaire can be played either with a real deck of cards or as an online game. The online version is more common. Solitaire is an online card game where the player is able to compete against themselves. The object of the game is to draw a card and place it in hierarchy order within four stacks. A stack is formed for each suit of card. Each stack must rank from ace to king. The player is to focus on the cards that are face down first and gradually work their sequence into a lengthy row. The stack can be picked up and merged onto another until there are no cards left to play and all 4 stacks are in proper card order.
