The goal of Ocean Pyramid is to remove all of the cards from the Pyramid. You get rid of cards by matching two cards that have the same rank.
To set up the pyramid, one card is dealt face up at the top of the playing area, followed by two cards beneath it that partially cover it, three beneath them, and so on, for a total of 28 cards dealt (or six rows of 21 cards). The Stock is made up of the remaining cards, which are placed to the side face down.
To play, if the values of two uncovered cards total 13, they can be removed to the foundation. As a result, kings may be quickly removed to the foundation. Cards must not be covered in order to be removed, therefore when an Ace lays on a Queen, that Queen cannot be removed. Cards that are discarded are no longer in play and cannot be re-matched with other cards.
