Two decks fill eight columns where face-up card groups move in any order, just like Outback, but you get two passes through the stock. Only a 20% win rate.

Adelaide Solitaire belongs to the Australian Patience family of solitaire games, in which whole groups of face-up cards may be picked up and carried to another column without regard to their order. Its layout is identical to Outback — eight columns of seven face-up cards, built down in suit, with two full decks in play — but it grants you two passes through the stock instead of one, which turns many otherwise hopeless deals into winnable ones.
Like its relatives, it takes its name from Australian geography — Adelaide is the capital of South Australia. It's a tough one, with only a 20% chance of winning, so skill and a little luck both matter.
If you like Adelaide, Outback Solitaire and Yukon Solitaire are worth a look too.
After Adelaide's double pass through the stock, original Solitaire is the natural next stop.

8 foundation piles: Build up from Ace to King in the same suit.
8 tableau piles: Build down in suit. Cards in groups can be moved in any order. Only Kings may fill empty spaces. At the start of the game, each pile is given 7 cards.
Stock: Click to turn over 1 card at a time to the waste pile. There is one redeal.
Waste: The top card can be played on the foundations or tableau.
There are eight foundation piles.
Any ace in the foundation may be transferred to any vacant pile.
A card can be added to a foundation pile only if it's one rank higher and the same suit as the pile's current top card, so the only card that fits on an 8 of clubs is a 9 of clubs. There can be no more than 13 cards in a pile.
The top card of each foundation can be moved back into play if another pile will accept it.
There are eight tableau piles of seven cards each, dealt in a downward fan with every card face-up.
A card can be added to a tableau pile only if it's one rank lower and the same suit as the pile's current top card, so the only card that fits on a 6 of hearts is a 5 of hearts.
Cards on the tableau that are not covered by another card are free to be played onto the foundation or any other tableau pile.
Only kings may fill empty spots in the tableau.
Furthermore, any face-up card in the tableau may be transferred to another tableau column where it fits, bringing all cards on top of it with it. The cards it carries do not need to be in any particular order.
There is one waste pile, and the remaining cards make up the stock.
When you click the stock, one card is dealt to the waste pile. You get two passes through the stock; when it runs out, the waste pile is turned over once to form a new stock.
The top card of the waste pile can be played to the tableau or foundation.
