Open Gargantua is Gargantua — Double Klondike under its older name — with the one change its name promises: the whole staircase is dealt face up. Two decks go into nine columns of one to nine cards, all showing, over a fifty-nine-card stock that turns one card at a time with one redeal. The tableau builds down in alternating colours, runs travel, and only a king may take an empty column. Eight foundations build up in suit; bank all 104 to win.
Shuffle two decks together. Deal nine columns: one card in the first, two in the second, up to nine in the ninth — forty-five cards, every one face up. The remaining fifty-nine form the stock. Above the tableau sit the stock, the waste and eight foundations.
An open deal turns Double Klondike from a game of discovery into a game of planning. Nothing in the tableau is unknown; the only surprises come from the stock, and the redeal gives you a second look at that. Use the information.
Open Gargantua is the open-deal member of the two-deck Klondike line, next to 8 x 8, Big Harp, Double Trigon and Inquisitor. Gargantua itself is Double Klondike with a single redeal; this game keeps that redeal and that king rule and simply turns every dealt card up. It stands to Gargantua exactly as Whitehead's open deal stands to Klondike.

Only the deal is open. Double Klondike hides every card but the top of each column; here all forty-five dealt cards are face up. The king rule, the one-card draw and the redeal are shared.
One. When the stock is empty, click it to turn the waste over and go through again; after that second pass the stock stays empty.
Only a king, or a packed run of alternating colours headed by a king. With two decks there are eight kings to choose from, so pick the one with hosts behind it.
Yes. With every dealt card visible you can plan which columns to empty and which king to seat, and the only unknown is the order of the stock.
Gargantua is the old name for Double Klondike with a single redeal. Open Gargantua is that game with the staircase dealt face up.
