Forty Thieves flipped on its head: you start from Threes, not Aces, and the Twos are the last cards home. Eight tight columns, two decks, one pass through the stock.

Three's Company Solitaire belongs to the Forty Thieves family, that strict school of two-deck patiences where every build stays in a single suit. The twist is baked into the name: the game starts not from Aces but from Threes, so the eight Twos are the very last cards each foundation ever receives.
At the deal, one Three is placed on each of the eight foundations, and from there the piles climb in suit — three, four, five, all the way up through the King, around the corner to the Ace, and home on the Two. The tableau is spare, just eight single-card columns, and it too insists on matching suits, so a Six of clubs will only ever accept the Five of clubs beneath it. That discipline is what makes the family so demanding, and with only eight columns to maneuver in, Three's Company is tighter still than its ten-column cousin Deuces Solitaire.
The game is challenging, with a modest win rate. It is played with two decks, and because the stock passes only once with no redeal, planning each release from the waste is everything.
If you like Three's Company, its parent game Forty Thieves Solitaire gives you the full ten-column, same-suit version this one strips down, and the original Solitaire is always there if you want something more classic.

There are eight foundation piles.
Each foundation pile starts with a Three already in place.
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, wrapping past the King to the Ace and the Two, so the only card that fits on a 6 of hearts is a 7 of hearts. 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.
Eight tableau piles of one card each, spread out in a row. Every card is 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 9 of clubs is an 8 of clubs.
Cards on the tableau that are not covered by another card are free to be played onto the foundation or any other tableau pile. A run of cards in the same suit and in descending order may be moved together.
Any card can fill an empty slot in the tableau.
There is one waste pile, and the remaining cards make up the stock.
When you click the stock, one card moves from the stock to the waste. You only get one pass through the stock, since there are no redeals.
The top card of the waste can be played to the tableau or a foundation.
