Race sixteen foundations in four directions at once across three decks, while six tiny tableau piles hold just one card each. Only 15% of deals are won.

Thomas Warfield built Racing Aces Solitaire as a three-deck spin on Aces and Kings Solitaire, and the name fits: sixteen foundation piles race in four directions at once. Four climb from Ace to King, four count down from Six to Ace, four climb from Seven to King, and four count down from King to Ace, so every rank in the deck is on the move somewhere. The tableau, by contrast, is bare-bones: six piles that never hold more than one card, refilled from the stock as you clear them. At a 15% win rate it's a tough one, and skill matters far more than luck here.
Double Aces and Kings Solitaire and Deuces and Queens Solitaire use the same four-way foundation trick, just with different starting ranks and deck counts.

16 foundation piles: Four piles build up from Ace to King, any suit. Four build down from Six to Ace, any suit. Four build up from Seven to King, any suit. Four build down from King to Ace, any suit.
6 tableau piles: Each pile holds only one card at a time. Empty piles refill from the stock; once the stock runs out, any card can fill the gap. One card is dealt to each pile at the start.
3 reserve piles: Each reserve starts with thirteen cards, dealt face-up. The top card of each is available for play to the foundations.
Stock: Click to deal one card at a time to the waste. There are no redeals.
Waste: The top card is available for play to the foundations or tableau.
Foundation piles come in four groups of four.
Aces Foundation: Any Ace can start an empty pile here. A card may be added if it is one higher than the pile's current top card, any suit, so the only card that can follow a 9 is a 10. A full pile runs from Ace to King, thirteen cards.
Sixes Foundation: Any Six can start an empty pile here. A card may be added if it is one lower than the pile's current top card, any suit, so the only card that can follow a 3 is a 2. Each pile runs from Six down to Ace, six cards, and then it's full.
Sevens Foundation: Any Seven can start an empty pile here. A card may be added if it is one higher than the pile's current top card, any suit, so the only card that can follow a 10 is a Jack. Each pile runs from Seven up to King, seven cards, and then it's full.
Kings Foundation: Any King can start an empty pile here. A card may be added if it is one lower than the pile's current top card, any suit, so the only card that can follow a 10 is a 9. A full pile runs from King down to Ace, thirteen cards.
Cards can be moved back off any foundation if another pile will accept them.
There are three reserve piles, each dealt thirteen cards face-up at the start. No cards can be moved into a reserve. The top card of each reserve can be played to an empty tableau pile or to a foundation.
There are six tableau piles, and none of them can hold more than one card. No building is allowed here at all.
A tableau card can be played to the foundation or to an empty tableau pile.
When a tableau pile is emptied, the stock immediately deals a new card into it. Once the stock is gone, any card can fill an empty tableau pile.
Only one card moves at a time; there are no sequences to carry.
The cards left after the deal make up the stock, and there is one waste pile.
When you click the stock, one card deals to the waste. You only get one pass through the stock, with no redeals.
The top card of the waste can be played to an empty tableau pile or a foundation.
