Tri Peaks (also known as Three Peaks, Tri Towers or Triple Peaks) is a solitaire card game that uses one deck and the object is to clear three peaks made up of cards.
The game starts with eighteen cards dealt face-down on the tableau to form three pyramids with three overlapping tiers each. Over these three pyramids are ten face-up cards.
The twenty-four remaining cards make up the stock. The first card from the stock is put in the waste pile. For a card in the tableau to be moved to the waste pile, it must be a rank higher or lower regardless of suit. This card becomes the new top card and the process is repeated several times (e.g. 7-8-9-10-9-10-J-10-9-8, etc.) until the sequence stops. Along the way, any face-down cards that are no longer overlapping are turned up.
