TriTowers also known as Tri Peaks and Triple Peaks is a simple solitaire game with the object to clear the board of all cards. The cards are arranged in three peaks with 18 cards face down, and a bottom row consisting of ten cards face up. You have a stock pile with the remaining cards beside a waste pile with one card facing up."
