8 x 8 is Double Klondike with the staircase flattened into a square. Two decks are dealt face up into eight columns of eight — sixty-four cards you can see from the first second — and the other forty wait in a stock that turns one card at a time to a waste, with unlimited redeals. The tableau builds down in alternating colours, a packed run travels as a unit, and any card may fill an empty column. Eight foundations build up in suit from the ace; win by banking all 104 cards.
Shuffle two standard 52-card decks together. Deal eight columns of eight cards, every card face up, across the tableau. The remaining forty cards form the stock, face down. Above the tableau sit the stock, the waste and eight foundation spaces — one for each suit, twice over.
With every card in view and the stock circling forever, 8 x 8 is a game of planning — the danger is not a hidden card but a column you bury under a run that has no host. Play it in this order.
8 x 8 is the open-square member of the two-deck Klondike line that Big Harp, Open Gargantua, Double Trigon and Inquisitor also belong to: the same alternating-colour build and travelling runs as Klondike, with the second deck doubling the foundations. Its sibling Eight Times Eight plays the identical board with only two redeals; with the stock turning without limit, 8 x 8 is the gentler of the pair and a good first two-deck game.

The deal. Double Klondike deals a hidden staircase; 8 x 8 deals eight open columns of eight, so every card is visible from the start. Any card may fill a space, and the stock recycles without limit.
Yes. A space takes any single card or any packed run of alternating colours. Kings have no special claim here, which makes spaces far more useful than in Klondike.
As many as you want. When the stock is empty, click it to turn the waste over and keep going. The stock never runs out for good.
Two decks mean two aces of each suit. Each suit builds up on two foundations, and either one accepts the next card of that suit.
Not every deal, but the game is generous. With every card in view and unlimited passes through the stock, a lost game is nearly always a buried run with no host, not bad luck.
