Twelve single-card piles, foundations pre-loaded with aces, and just one pass through the deck: if a move is legal here, you'd better take it.

Fortune's Favor Solitaire is the one-deck little sibling of Busy Aces, trimmed down until barely any game is left. Twelve single-card piles, four foundations that start pre-loaded with an ace apiece, and just one pass through the deck. There's so little room to maneuver that luck barely factors in: if a move is legal, take it.
When you want the classic feel stripped of gimmicks, Solitaire is one pass away. You might also like Busy Aces Solitaire, the two-deck game it's based on, and Preference Solitaire.

Have fun playing!
There are four foundation piles, each dealt a starting ace.
A card joins a foundation pile only if it's one rank higher than the pile's current top card and matches its suit. So the only card that can land on the jack of clubs is the queen of clubs.
You can move a foundation's top card back into play if another pile will take it.
Twelve tableau piles hold one card each, all dealt face-up.
A card can be added to a tableau pile only if it's one rank lower than the pile's current top card and shares its suit. So the only card that can land on a 9 of clubs is an 8 of clubs.
Any tableau card left uncovered is free to move to a foundation or another tableau pile. You can move just one card at a time; there's no moving groups of cards together.
When a tableau slot empties, it's refilled right away: first from the waste, then from the stock once the waste runs out, and with any card once the stock runs dry too.
The rest of the deck becomes the stock, with a single waste pile next to it.
Click the stock to deal one card to the waste. You get only one pass through the deck, so spend it carefully.
The top card of the waste can be played to the tableau or a foundation.
