Juggle four kinds of foundations at once, straight runs, odds, evens, and kings, while clearing sixteen single-card piles with zero tableau building. Win rate: 60%.

Royal Rendezvous Solitaire is an unusual Austrian game built around four separate kinds of foundations: one for straight runs, one for odd ranks, one for even ranks, and one just for kings. There's no building at all on the tableau, so the whole game comes down to clearing sixteen single-card piles into the right foundation at the right time. It's also known as Royal Appointment. At a 60% win rate, this stays a simple, quick game to pick up. It's played with two decks, and luck matters about as much as skill.
Twenty Solitaire and Carpet Solitaire share the same idea of a wide, single-card tableau with no building, and are worth a look if you like this one.

4 Top Ace foundations: Build up in suit from Aces to Kings. An Ace of each suit is dealt here at the start of the game.
4 Lower Ace foundations: Build up in suit from Aces to Jacks, two ranks at a time. An Ace of each suit is dealt here at the start of the game.
4 Twos foundations: Build up in suit from Twos to Queens, two ranks at a time. A Two of each suit is dealt here at the start of the game.
4 King foundations: As they become available, place a King of each suit in these piles. No building is allowed here.
16 tableau piles: The top card can be played on the foundations. There's no building. Empty spots are filled immediately from the waste, or from the stock if the waste is empty. At the start of the game, each pile is dealt one card 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.
Foundation piles come in four types.
Top Ace foundations:
These four piles each start with an Ace. A card may be added if it is one higher than the pile's current top card and of the same suit, so the only card that can go on a 9 of clubs is a 10 of clubs. Each pile can hold up to 13 cards, all the way to the King.
Lower Ace foundations:
These four piles also start with an Ace, but build up two ranks at a time in the same suit, so the only card that can go on a 7 of hearts is a 9 of hearts. Each pile stops at six cards, topping out at the Jack.
Twos foundations:
These four piles start with a Two and build up two ranks at a time in the same suit, so the only card that can go on an 8 of hearts is a 10 of hearts. Each pile stops at six cards, topping out at the Queen.
King foundations:
Each of these four piles takes a single King, and every pile must start with a different suit. No building is allowed here.
Once a card is placed on any foundation, it stays there.
There are sixteen tableau piles of one card each, all dealt face-up.
No building is allowed on the tableau.
Any exposed tableau card can be played onto the foundations.
Empty tableau spots are filled immediately from the waste. If the waste is empty, a card comes from the stock instead. If the stock is also empty, the spot stays open.
Only one card may be moved at a time; sequences aren't allowed.
There is one waste pile, and the remaining cards make up the stock.
Click the stock to deal one card to the waste. There's only one pass through the stock; no redeals.
The top card of the waste is available for foundation play.
