Double Solitaire or Double Klondike, is the same game as Classic or Klondike Solitaire, except that it is played with two decks or 104 cards.
Your goal is to move all 104 cards from the stockpile and tableau into the eight foundation piles by suit in ascending order from Ace to King. There are two foundation piles for each suit.
Gameplay is similar to Klondike Solitaire.
Turn 3 Double Klondike is the same game, except you turn 3 cards from the stockpile at the time. You can also try Turn 3 Klondike and Triple Klondike.
