Use one pack of cards.
Shuffle and then deal out a card faced down.
Deal out two more cards faced down in a row centered over the first card and then three more cards faced down in a row centered over this row to form a peak.
Repeat the last two steps twice more to form a total of three consecutive peaks.
Deal out ten more cards, facing up, to form a fourth row centered over the nine cards forming the bottom of the three peaks.
Place the remaining twenty-four cards faced down in a pile to create the stock.
To move all the cards to the stock.
Turn over one card at a time from the stock to the discard pile. The stock can only be dealt through once.
Cards can be moved to the discard pile if they are one higher or one lower in value that the top card on the pile regardless of suit.
Aces can be placed on Kings and Kings can be placed on Aces.
When a faced down card is no longer covered by any other cards, it can be revealed by turning it face up.

The next move would be to move the Six of Clubs to the discard pile as it is one less that the Seven of Hearts.
This would then allow the two cards which the Six of Clubs was covering to be revealed..
