no card on the tableau can be put over the top card of the waste pile, a card is placed on the waste pile from the stock to see if it can start a new sequence. Along the way, any face-down cards that are no longer overlapping are turned up. This card becomes the new top card and the process is repeated several times (e.g. For a card in the tableau to be moved to the waste pile, it must be a rank higher or lower regardless of suit. The first card from the stock is put in the waste pile (sometimes known as the foundation/discard). The twenty-four remaining cards make up the stock. This is built by dealing out ten cards face-up in a row then nine cards face-down above them, offset by half a card to the right then six cards above those, offset by the same amount (and leaving a one-card gap after the second and fourth cards) then three cards to cap the three pyramids. The game starts with eighteen cards dealt face-down on the tableau to form three face-down "pyramids" of six cards each, and a row of ten cards beneath. It was created by Robert Hogue in 1989, and popularized as a result of being included in Microsoft Solitaire Collection. The game uses one deck and the object is to clear three peaks made up of cards.

Tri Peaks (also known as Three Peaks, Tri Towers or Triple Peaks) is a patience or solitaire card game that is akin to the solitaire games Golf and Black Hole. For the running trail, see Three Peaks Challenge.
