Taking a standard deck of playing cards (without Jokers), deal one upturned card on the left of your playing area, then six downturned cards. On top of the downturned cards, deal an upturned card on the left-most downturned pile, and downturned cards on the rest until all piles have an upturned card.
The four foundations are built up by suit from Ace to King, and the tableau piles can be built down by alternate colours, and partial or complete piles can be moved if they are built down by alternate colours also. Any empty piles can be filled with a King or a pile of cards with a King at the top.
There are different ways of dealing the remainder of the deck: some choose to turn three cards at once to the waste, and allow three passes through the deck, others turn only one over, but only pass through the deck once. Others don't limit the number of passed through the deck.
