The deal

Four cards begin the reserve and 48 cards wait in stock. Only each reserve pile’s top card is available.

Playing the cards

Build existing foundations up by suit, wrapping King to Ace. Begin new foundation columns in order, following the first column’s suit order. Deal a card to each reserve pile when no foundation play remains.

Goal and first plan

Move all 52 cards to foundations.

Before starting a new foundation, check whether that reserve card fits an existing one. If two exposed cards share a suit, only the lower rank can start a new foundation.
