Remove all the cards from the funnel.
Match pairs of exposed cards where their total value adds up to 13. In this game, a Jack is worth 11, a Queen is worth 12, a King is worth 13 and an Ace is worth 1. Kings are removed on their own. If one card of a pair is partially covered by the other, tap on the exposed card first. Tap on the stock to turn over a card to each of the two piles. The stock can only be dealt through once.
