First, the player has to remove the aces from the deck and align them vertically without overlapping them. They form the foundations. Then cards are dealt to the left and right of the aces, forming eight rows of six overlapping cards each.
The top card of each row (the cards that are exposed) is available for play either on the foundations or on any other row. The foundations are built up to Kings in suit and the rows are built down regardless of suit. Once a row becomes empty, it is filled by any card.
The game is won when all of the cards are built onto the foundations. But this is easier said than done because most games are doomed to fail in just a few moves.
