The Fifteen (Double Deck Solitaire Game)

Two Entire Packs Of Cards

Rules

1. Only cards in the seventh or lowest row are available, until by their removal those above them are released. No card can at any time be used that has any other below it.
   Note.—There is one exception to this rule, in case the game cannot be opened. See below.
2. Each foundation must follow suit.

Play

Deal out the entire pack from left to right in horizontal rows, fifteen cards in each, excepting the last one, which can only contain fourteen. Each row should partly cover over the preceding one; four aces and four kings form the foundation cards, the aces ascending in sequence to kings, the kings descending in sequence to aces. When the deal is complete, if any foundation cards should appear in the lowest row (Rule 1), play them at once on the spaces reserved, and also any other suitable cards— then marry, both in ascending and in descending lines, subject to Rule I; but if, after these changes, no foundation card is available, so that the patience cannot even begin, you may withdraw from the sixth row one ace and one king, if any are to be found (see note to Rule 1), immediately filling the spaces so made with the cards below which had previously blocked them. If even this resource is unavailing, the patience has already failed, there being no re-deal, and no further infringement of rules allowed.

When one or more foundations are established, examine the tableau carefully, marry all available cards, and endeavor by these changes to release the greatest number of suitable cards for the foundations, and to open out one or more perpendicular lanes. These are of the greatest use; you may select any available card and place it at the top of the lane, and below it any others in sequence of the same suit, each card partly concealing the preceding one, as in the original deal.

You may also use the lane for reversing any sequences previously made. Thus, supposing there is a sequence beginning with, a ten and ending with a three (the ten being required for one of the foundations), place the three at the top of the lane, the other cards following until the ten becomes the lowest or available card.
In theory this patience is simple, but it is very difficult to play. The combinations are endless, from the constant reversing of sequences, and require great attention. As the success principally depends on the lanes, it is more prudent, when you have only one, not to refill it until by some fresh combination you can open out another one.

There is no re-deal.
