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.
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.
All building is carried out on the single waste pile. Any completely uncovered card in the tableau may be moved to the waste pile if it follows either an ascending or descending sequence regardless of suit. So in the above example, either the 6, the 6 or the 8 may be built on the 7. Sequences may turn the corner with Kings building on Aces and Aces building on Kings. When no more cards can be transferred from the tableau to the waste pile, a card from the stock is dealt to the waste pile and building resumes. When the stock is exhausted, and no more building can occur, then the game is over. You'll receive a bonus every time you completely demolish one of the three peaks and you'll also receive a bonus for each card that remains in the tableau when you win the game, along with another bonus depending on how fast you completed the game. Don't forget, you can double click or right click on a card to send it flying to the waste pile.
