The object of Tri-Peaks is to transfer all the cards from the tableau to the waste pile, uncovering cards further up the peaks, making them available for play. You win the game when you've removed all the cards from the tableau to the waste pile, demolishing the three peaks.
The game is played with a single pack of 52 playing cards. The cards are dealt to form a tableau consisting of three overlapping peaks in the arrangement shown below. A single card is then dealt face up from the remaining stock to start a waste pile that is built on during the game.
