Pyramid Solitaire is a different version of the well-known Solitaire, and as its name suggests, it is a pyramid-shaped solitaire.
The goal of this game is to dismantle the pyramid, so you have to remove cards in pairs that add up to 13 points, for example a 9+4 or 8+5 and so on, until you reach your final aim.
It is very simple to run this game. It does not require any previous installation, and if it were not enough, it is fully free-of-charge.
