Complete guide
Sly Fox is a complete browser implementation with its own versioned rules profile. Alternate between clearing a twenty-pile reserve and assigning controlled stock cycles to eight opposed suited foundations.
Each suit begins with one Ace foundation rising and one King foundation falling; twenty reserves receive one card apiece, and seventy-six cards remain in stock.
During the opening reserve phase, move exposed reserve cards to their suited foundations and refill each vacancy from stock. Begin a stock cycle only when no such foundation move remains; then each stock top must go directly to a foundation or onto a chosen reserve, with the phase returning after twenty placements.
Complete all eight suited foundations, four from Ace to King and four from King to Ace, using both decks. Near completion, assign each stock card to the reserve whose exposed chain reaches a foundation first, keeping upward and downward suit paths balanced.
Clear every forced reserve continuation before starting a cycle, and spread difficult stock cards across reserves whose current tops will not hide near-term foundation successors. Starting the twenty-card cycle while a reserve card can still advance a foundation is illegal, and stacking blindly can bury both directions of the same suit.
