There are four different types of piles in Gargantua solitaire. They are:
The Draw: The pile of facedown cards in the upper left corner.
The Waste: The faceup pile next to the Draw in the upper left corner.
The Foundations: The eight piles in the upper right corner.
The Tableau: The nine piles that make up the main table.
Gargantua solitaire is a two-deck version of Klondike
45 cards are dealt out into nine piles, in the following manner: The first pile (left to right) includes one card, the second pile includes two cards, the third pile includes three cards, etc., so that the last pile has seven cards.
The top card on each pile is turned face up.
The cards that are left after setting up the tableau are placed in the draw pile, face down.
Build all eight foundations up from ace to king in separate piles.
Turn cards from the draw pile over one at a time. If the card you turn over is playable (either on a foundation or on the tableau), you may do so.
As they become available, the aces must be played onto the foundations. Cards of the same suit may be played on each ace in ascending order, from low (2) to high (king).
On the tableau, cards are played in descending order, alternating colors.
If a column in the tableau is emptied, any visible king can be moved to fill that space.
