From Alan Colburn:
This is the popular solitaire game called Pyramid. When a game begins, the program will shuffle the deck and lay out 28 cards, face up, in a pyramid pattern. The remaining cards are placed in the stock, face down. To play, click on pairs of available cards whose ranks add to 13 (e.g., 5+8, or A+Q). Available cards are those not overlapped by other cards. The game provides instructions. This version includes sounds (Mr. Burns from the Simpsons), which can be turned off. It also keeps track of high scores. Other than the program file and a config.ini file, no additional files are added to your hard drive & no registry entries are created.
