Remove all the cards.
Cards can be moved between working stacks regardless of suit or value. Only one card at a time can be moved between working stacks. Empty spaces can be filled by any card. When each stack has at least one card, and the total value of the top cards is 91, the top cards are removed. In this game, a Jack is worth 11, a Queen is worth 12, a King is worth 13 and an Ace is worth 1. A complete set of cards from Ace to King has a total of 91.
