Use one pack of cards.
Shuffle and deal out twenty-one cards, all facing down, to the six rightmost working stacks with, from left to right, one, two, three, four, five and six cards in them.
Deal out five cards, all facing up, to each of these stacks.
Place the last card, facing up to the left to form a seventh stack.
To move all cards to the foundations.
Foundations are built up by suit from Ace to King.
Working stacks are built down by alternate color.
Sequences of any cards can be moved between working stacks, providing the drag card is allowed on the destination stack.
Empty spaces can be filled by a King or a sequence starting with a King.
Avoid having long working stacks of cards that are hard to break up later.
