Tripeaks is a classic solitaire variation where you stack cards on a pile that are 1 away from the card pile.
So if the card on the pile of cards is 10, you can place a 9 or Jack, from the table of revealed cards, on top of the card pile.
There are 25 different levels to complete. Based on your score a Bronze, Silver, or Gold badge will be awarded for a level.
The total score is calculated by adding up all the scores of all the levels.
