A tougher, two-deck cousin of Busy Aces with fewer tableau piles to work with. Chance calls more shots here: just a 25% win rate.

With fewer tableau piles, this is a more challenging version of Busy Aces Solitaire.
According to Thomas Warfield, Deuces Solitaire was first published in 1860 as "Le Deux" in Le Livre Illustre des Patiences, an early collection of games published in Brussels. Warfield has made a number of similar games. Difficulty here sits at medium, and you'll clear the board about 25% of the time across two decks; chance drives that number more than skill does.
One of its nearest relatives in the catalog is Cast Out Nines Solitaire, which flips the setup by making you dig each foundation's starter cards out of the deck instead of dealing them upfront.
If you enjoy Deuces, try Spider Solitaire too, since both games build the tableau down in the same suit.
If you run into anything odd or have an idea that would make the game better, please contact me.

Waste: Top card available for play on the foundation or tableau.
There are eight foundation piles.
Each pile starts with a two.
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. Building wraps from King to Ace, so the only card that fits on a King of diamonds is the Ace of diamonds. Each pile holds up to 13 cards.
The top card of each foundation can be moved back into play if another pile will accept it.
Ten tableau piles of one card 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 4 of diamonds is the 3 of diamonds.
Any tableau card that isn't covered by another card is free to be played onto the foundation or any other tableau pile.
Any card can fill an empty slot in the tableau.
Officially, only one card moves at a time, but the game lets you drag a whole run when there are enough empty columns to do it as a series of single moves.
There's one waste pile, and the remaining 86 cards make up the stock.
Click the stock to deal one card to the waste. You get only one pass through the stock.
The top waste card can be played to the tableau or foundation.
