Gaps is my personal favorite solitaire card game. You're trying to line up the cards from left to right by suit. You can do this by moving cards into the game. First click the card you want to move, then click the gap you want to move that card in to. You can move a card into a gap if it is one more than the card to the left of the gap and of the same suit, or one less than the card to the right and of the same suit. If you get stuck, you can shuffle the cards that aren't in order up to 3 times in a game.
