Christmas Gaps Solitaire is a festive Christmas themed solitaire card game where your goal is arrange the cards into four rows from 2 - King by suit. The cards are dealt into 4 rows with the 2s on the left. The Aces are removed to create Gaps, and you arrange the cards by moving them into the Gaps. You can move a card into a Gap if it continues a sequence from the right or the left of the gap and is of the same suit as the card you are moving into the Gap. A card continues the sequence from the left if the card you are moving in has the same suit as the card on the left and a value one more than that card. A card continues a sequence to the right if the card you are moving into the gap has the same suit as the card on the right and a value one less than it. As the cards create a sequence from the 2s on the left side of the game screen, you get highlighted. Up to three times in any given game you can click the 'Shuffle' button. This will shuffle all the cards that are not currently highlighted.
