Gaps

Gaps is a one-deck patience game from the Montana family, in which the whole pack is dealt face up into four rows of thirteen cards and the four aces are then taken out, leaving four empty spaces. A player may move a card into a space only if it is the same suit and one rank higher than the card standing to the left of that space, so each row slowly grows into a run in suit. A space immediately to the right of a king is dead and takes nothing, and a space at the left end of a row takes only a two. When no move is left the unsorted cards are gathered and redealt, usually with a space left after each correct run, and the usual rules allow only a few redeals. The aim is to finish four rows running from deuce to king. The game is also known as Montana, Spaces or Vacancies, and Addiction is a close variant.
