Corona is a relatively long and difficult solitaire game using two decks. According to SolSuit Solitaire, there is only a 1 in 25 chance of winning (SolSuit). The object of the game is to move all of the cards to the Foundations.
Corona has eight Foundations that build up in suit from Ace to King.
Here is an example: Ace♥, 2♥, 3♥, 4♥...
There are twelve Tableau Piles that build down in suit.
Here is an example: 10♦, 9♦, 8♦, 7♦...
The Deck deals out one card at a time. (SolSuit)
Only one card on can be moved at a time, and this is the top card on each Tableau Pile or the single card being dealt. These cards can be played onto the Foundations or onto other Tableau Piles. The card being dealt from the Deck automatically fills the empty spaces in the Tableau Piles (Solavant). Only one pass through the Deck is allowed (Tesseract Mobile). Corona is won once all cards have been moved to the Foundations.
