Clear eighteen piles by pairing cards that add up to fourteen, a King with an Ace, a Queen with a Two, and ride an 86% win rate across two decks.

Double Fourteens Solitaire is Fourteen Out Solitaire played with two decks instead of one: eighteen piles hold every card face-up, and your job is to clear pairs that add up to fourteen — a King and an Ace, a Queen and a Two, an 8 and a 6, and so on. It's a simple game, with an 86% chance of winning, and skill matters more than luck.
The moves work exactly the same as in the single-deck original, just with twice the cards to sort through. If you want even more piles to clear, Triple Fourteens Solitaire adds a third deck.

18 tableau piles: There are 18 tableau piles, with the top card of each pile available. Pick up one card with the mouse and drop it on another to clear a pair that adds up to fourteen — a King and an Ace, for example, a Queen and a 2, or an 8 and a 6. At the start of the game, six cards are dealt to each of the first fourteen piles, and five cards are dealt to the remaining four piles.
Foundation pile: A hidden pile where cleared pairs are set aside.
There is one foundation pile, where matched pairs are set aside once you clear them. It stays hidden during play.
There are eighteen tableau piles: the first fourteen have six cards each, and the last four have five cards each. Every card is dealt face-up.
On the tableau, no building is allowed — cards simply wait to be paired off.
Cards on the tableau that are not covered by another card are playable.
The tableau's empty spaces may not be filled.
