Watch empty tableau slots refill themselves from the waste and stock as you take on a two-deck game with just a 25% win rate.

Corona Solitaire plays a lot like Forty and Eight Solitaire, with empty tableau slots refilled automatically from the waste and stock instead of sitting open. It's a medium-difficulty game with a 25% chance of winning, played with two decks, where skill and luck both have a say in the outcome.
Its closest relative is Quadrangle Solitaire, another two-deck game built on the same bones. Richard's Patience, Triple Line, Busy Aces, Limited, and Crown all belong to the same family. If you'd rather ease into the basics first, original Solitaire is always there too.
If you run into anything odd or have an idea that would make the game better, please contact me.

8 foundation piles: Build up from Ace to King in the same suit.
12 tableau piles: Build down in suit. Only one card can be moved at a time. Empty spots are refilled from the waste, or from the stock if the waste is empty. Each pile starts with three cards, all face up.
Stock: Click to turn over 1 card to the waste. There are no redeals.
Waste: The top card is available for use on the foundations or tableau.
There are eight foundation piles.
Any ace can be placed on any empty foundation 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 a 7 of diamonds is an 8 of diamonds. A pile can hold no more than 13 cards.
The top card of each foundation pile can be moved back into play if another pile will accept it.
Twelve tableau piles of three cards each, all dealt 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 jack of diamonds is a 10 of diamonds.
Any tableau card not covered by another card is free to play onto the foundation or another tableau pile.
An empty tableau spot is filled right away with a card from the waste. If the waste is empty, a card comes from the stock instead. If the stock is empty too, any card can fill the spot.
Only one card may be moved at a time; sequences are not permitted.
There's one waste pile; the rest of the cards make up the stock.
Clicking the stock deals one card to the waste. You only get one pass through the deck.
The top card of the waste can be played to the tableau or foundation.
