How to play
Complete all eight thirteen-card foundations with both decks.
- The four Aces and four Kings seed the foundations. Twenty tableau piles receive one card each, one card begins on the waste, and the remaining seventy-five cards form a one-pass stock.
- A tableau top or waste card may advance its matching outward foundation. The waste may be placed on a tableau pile without a build sequence; when a pile empties it is automatically refilled from the waste, then the stock. There is no redeal.
- Complete all eight thirteen-card foundations with both decks.
Strategy tips
- Choose stock-placement piles whose top cards are already close to a foundation, so burying one blocker does not create another.
- The twenty piles are not rank-building columns; their purpose is to expose one playable top and hold stock cards temporarily.
- Before exhausting the stock, compare every pile top with both directions for its suit and clear short piles that would otherwise auto-refill at a bad time.
