Gargantua Solitaire is a two-deck version of Klondike.
Player is first dealt 45 cards into 9 piles as following:
The first pile has 1 card, the second pile 2 cards, the third pile 3 cards, etc., so that the last pile has 9 cards.
The top card on each pile is turned face up, so that there are 9 face-up cards.
The remaining cards make up a draw pile.
Foundations are built up by suit, from ace to king.
On the tableau, cards are built down by alternating colors.
Anytime a card is moved from one pile of the tableau to another, face-down top card from the tableau is turned face up.
An empty tableau can only be filled with a King and can then be played in descending order.
When the player gets stuck he can click on the draw file. This will deal 1 card at a time onto the waste pile.
The player may move the top card from the waste pile into the tableau or to the foundations to continue.
When the draw pile is out of cards, the player can reset the draw pile and continue.
