TriPeaks

The object of TriPeaks is to clear the board by removing cards in order. The order is:
King, Queen, Jack, 10, 9, 8, 7, 6, 5, 4, 3, 2, Ace

The order repeats, so you can go from Queen, to King, to Ace, then back to King. As long as you pick a card immediately in front of or behind the card in the draw pile. You can clear the board multiple times in 1 game.

Pyramid

The object of Pyramid is to match 2 cards that add up to 13. King is worth 13 (you can just click a King to clear it without matching it), Queen is 12, Jack is 11, and Ace is 1. Below is the list of pairs that will work. The suit does not matter, just the number. You can clear the board multiple times in 1 game.

King = 13
Queen + Ace = 13
Jack + 2 = 13
10 + 3 = 13
9 + 4 = 13
8 + 5 = 13
7 + 6 = 13

You can clear any combination of the 2 games. You could clear 50 of each, or 100 of TriPeaks and 0 of Pyramid. It is up to you. Eventually, you will have to play 100 of both TriPeaks and Pyramid to get these 2 achievements.
