Three decks feed twelve foundations and nine face-up reserve piles, letting you plan the whole puzzle before you start: a simple 95% win rate.

Algiers Solitaire triples the deck and the difficulty of Carthage Solitaire: three full decks feed twelve foundations and twelve single-card tableau piles, backed by nine reserve piles of six cards apiece. Every card is dealt face-up from the start, so you can see the whole puzzle and plan several moves ahead. Once a reserve pile empties out, it becomes a one-card parking spot, which is often the only breathing room you get. Clicking the stock deals two fresh cards onto each reserve pile, and once the stock runs dry, that's it, no reshuffling.
The game is simple, with a 95% chance of winning, and skill decides most games here, not luck. It plays a lot like Algerian Patience, and shares its bones with Carthage Solitaire.
If you enjoy Algiers, try the original Solitaire too.

12 foundation piles: Build up from Ace to King in the same suit.
12 tableau piles: Built down in suit. Only one card can be moved at a time. Any available card is used to fill the spaces. At the start of the game, each pile is dealt one card.
9 reserve piles: The top card can be played on the foundations or tableau. At the start of the game, each pile is given 6 cards. Each empty reserve pile holds one tableau card.
Stock: Clicking deals two cards to each reserve pile.
There are twelve foundation piles.
Any ace can be placed on an 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 4 of spades is a 5 of spades. There can be no more than 13 cards in a pile.
The top card of each foundation can be moved back into play if another pile will accept it.
Nine reserve piles start with six cards each, all dealt face-up so you can see everything from the first move.
You can't build anything onto the reserve.
Cards on the reserve that aren't covered by another card can be played onto the foundation, any empty reserve pile, or any tableau pile.
Any card can fill an empty slot in the reserve.
Only one card may be moved at a time; sequences are not permitted.
Twelve tableau piles start with one card each, 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 7 of spades is a 6 of spades.
Cards not covered by another card on the tableau are free to be played onto the foundation, any empty reserve pile, or any other tableau pile.
Any card can fill an empty slot in the tableau.
Only one card may be moved at a time; sequences are not permitted.
The stock is made up of leftover cards.
Each time you click the stock, two cards are dealt onto each reserve pile. Once the stock is empty, there's no reshuffle, so use those cards wisely.
