Build tableau runs by rank alone, any suit welcome, in this loosened Rouge et Noir spin-off. Two decks and a 90% win rate make it one of the friendliest games here.

This is Thomas Warfield's Rouge et Noir variant, where you build tableau sequences independent of suit instead of alternating colors.
The game is named after Lady Adelaide Cadogan, who wrote one of the earliest solitaire manuals back in the 1870s. It's simple, with a 90% chance of winning, played with two decks, and your odds mostly come down to skill.
If you enjoy Lady Cadogan Solitaire, try classic Solitaire too. Lady Cadogan itself is a Rouge et Noir Solitaire variant, and Forty Devils Solitaire blends the two, so give both a try as well.

8 foundation piles: Build the left four piles up in suit from Ace to King. The right four piles only accept a complete 13-card sequence of the same suit moved over from the tableau.
10 tableau piles: Build down regardless of suit. Cards in sequence down in the same suit can be moved as a group. Only Kings, or a valid sequence led by a King, can fill an empty pile. At the start, the first pile gets one card, the second gets two, and so on up to ten. The top card of each pile is turned face-up.
Stock: Click to deal one card to the waste pile. You can redeal as many times as you like.
Waste: The top card can be played to the foundations or tableau.
Foundation piles come in two types.
The Left Foundation
The left foundation has four piles. Any ace can start a pile, and each pile must start with a different suit. A card can be added if it's one rank higher and the same suit as the pile's current top card, so only the jack of diamonds can go on a 10 of diamonds. Each pile holds up to 13 cards.
Right Foundation
The right foundation has four piles. You can't move single cards here. Only a complete ace-to-king sequence built on the tableau, all thirteen cards at once, can move over.
You can move cards back off any foundation, too.
Ten tableau piles: the first has one card, the second two, the third three, and so on. Only the top card of each pile is face-up; the rest are face-down.
A card can be added to a tableau pile only if it's one rank lower than the pile's current top card, regardless of suit, so the only card that fits on a nine is an eight of any suit.
Cards on the tableau that are not covered by another card are free to be played onto the foundation or any other tableau pile.
Only Kings may fill an empty tableau pile.
You can move a sequence of cards from one pile to another as a group, but only if they're all the same suit.
There's one waste pile; the rest of the cards form the stock.
Clicking the stock deals one card to the waste. You can go through the stock as many times as you like.
The top card of the waste can be played to the tableau or foundation.
