The Gap is a one-deck patience. The game is begun by dealing all the cards except the Aces to the tableau with 4 empty spaces (gaps).
The object of the game is to arrange the cards into four sequences of 12 cards of the same suit, running from Twos to Kings.
Fill in a gap so that the cards are arranged up in suit. To move a card, just click it. In Figure, you can fill the gap in the upper row either with J or with 3.
After you have exhausted all the plays among the tableaus, click the Deal button. All cards that are not in suit sequence starting from a Two in the leftmost position of the row will move randomly to another place. Three redeals are allowed.
