Pyramid 13 is a clean and simple version of the popular pyramid solitaire game. Pyramid is easy to learn and quick to play.

Match pairs of cards adding up to 13 and see how many points you can accumulate. Keep increasing your score until you are unable to clear all of the cards in the pyramid.

You can customize the game by playing with your choice of three different card styles:
* Traditional suited cards with ace through king
* Color-coded cards numbered 1-13
* Geeky hexadecimal and binary

Personalize the card backs with your favorite color or a favorite photo.

Customize the background using the high-quality included backgrounds, or select up to three of your own photos to use as custom backgrounds. You can even randomize the backgrounds, giving you a new look with each pyramid played!

Game Center support is provided so you can compare your high scores with those of your friends and everyone else playing the game. There are several achievements available as well, ranging from straightforward to difficult.
