Gap Solitaire is not as well known as a lot of other solitaire card games, but it's my personal favorite. You need to get 4 rows of cards in order from 2 - King by suit. You do this by moving cards into the gaps. You can move a card by clicking on the card you want to move, then clicking on the gap you are moving the card in to. You can only move a card into a gap, if it is one greater than the card to the left of the game and of the same suit, or if it is one less than the card to the right of the gap and of the same suit. Up to 3 times in a given game, you can shuffle all the cards that are not currently in order.
