What is Crescent Solitaire?
Crescent is a two-deck patience game built around a semicircular tableau of sixteen fan stacks, arranged in a crescent around eight central foundation piles. Four foundations build ascending from Ace to King; four build descending from King to Ace, one ascending and one descending per suit. The same-suit tableau build rule and the rotation mechanic (which shifts all stacks instead of drawing individual cards) give Crescent a distinctive rhythm found in no other common solitaire.
Full rules
Two 52-card decks are used. One Ace and one King per suit anchor the eight foundations. The remaining 96 cards fill sixteen tableau stacks of six cards (top card face-up). A top card moves to a same-suit stack one rank away, or to its foundation. When stuck, rotate: every stack shifts clockwise, revealing the next bottom card as the new top. Win when all 104 cards reach foundations.
Bidirectional foundations and suit tracking
Tracking both foundation directions for all four suits is the central cognitive task. A 7 of clubs plays up if the ascending clubs foundation is at 6, or down if the descending foundation is at 8. Missing either opportunity wastes a rotation. Before rotating, always scan all eight foundation tops against the current sixteen stack tops.

The rotation mechanic
Rotating the crescent simultaneously changes all sixteen stack tops. A rotation that unlocks three foundation plays is excellent; one that unlocks none is wasted. The decision of when to rotate — and which foundation plays to clear before doing so — is the primary strategic lever in Crescent. Clearing the maximum number of foundation moves before each rotation is the clearest way to improve win rates.
