|A Patience game|
Gargantua is a solitaire card game that is basically a version of Klondike using two decks. It is also known as Jumbo in AisleRiot Solitaire (which is part of the GNOME Desktop).
Instead of seven in Klondike, there are nine tableau piles to be formed. Forming these nine tableau piles of cards, i.e. dealing the cards, is like much like Klondike. One face-up card is placed on the first column, then eight cards are each placed face-down on the other eight tableau piles. Over these eight face-down cards are one face-up card and seven face-down cards, and so on until all nine tableau piles have a face-up card. The rest of the deck becomes the stock. The foundation/tableau should look like this:
O O O O O O O O ┌─┐ ┌─┐ ┌─┐ ┌─┐ ┌─┐ ┌─┐ ┌─┐ ┌─┐ ┌─┐ │ │ ├─┤ ├─┤ ├─┤ ├─┤ ├─┤ ├─┤ ├─┤ ├─┤ └─┘ │ │ ├─┤ ├─┤ ├─┤ ├─┤ ├─┤ ├─┤ ├─┤ └─┘ │ │ ├─┤ ├─┤ ├─┤ ├─┤ ├─┤ ├─┤ └─┘ │ │ ├─┤ ├─┤ ├─┤ ├─┤ ├─┤ └─┘ │ │ ├─┤ ├─┤ ├─┤ ├─┤ └─┘ │ │ ├─┤ ├─┤ ├─┤ └─┘ │ │ ├─┤ ├─┤ └─┘ │ │ ├─┤ └─┘ │ │ └─┘
As in Klondike, play consists of the following:
As for dealing the stock, cards from it are dealt to the waste pile one at a time and used if possible. The stock can only be dealt twice; afterwards the leftover cards are left at the waste pile. Also note that if you do go through the stock twice you will almost always win, so for a little more challenge just go through it once.
The game is won if all cards are transferred to the foundations.
Harp, like Gargantua, is a solitaire card game that is basically a version of Klondike using two decks. It is played like Gargantua except that the stock can only be dealt four times.
The most simple version involves two packs, with eight foundation stacks rather than four. Instead of the standard seven columns of cards used in normal Klondike, twelve columns are used for two packs, sixteen for three packs.
As the number of packs used rises, it becomes harder to complete the game, due to the increase in the proportion of suits to stacks (four to seven in single pack games, eight to twelve in two pack games, twelve to sixteen in three pack games). The standard numbers of foundation stacks and columns are shown in the table for different numbers of starting packs.
For 15 or more packs, an alternative starting layout is generally used with more columns, and fewer cards in the longest columns. Instead of the cards being laid out in a triangle, with one card face up in each row, two cards are turned up - one at each end of each row. A game with 20 packs would use 62 columns, with the two middle columns having just 31 cards.
