Select a card, then choose a highlighted destination.
Playing the cards
Markers Ace through Eight identify each foundation’s step size. Bases start at twice each marker. Draw from the stock into four waste piles, then build any foundation at its interval regardless of suit; a total above thirteen wraps around.
First plan
Reserve different waste piles for ranks that serve different step sequences.
A card can fit more than one interval foundation, so check which waste pile will be exposed next.
