Pyramid Pile Up is an online puzzle game where the player must fill an empty pyramid with food tiles. Play agains the Chompies--flying squirrel monsters that fall from the sky to munch on your work. Strategy is key, not speed, as only a limited number of moves are allotted to build the pyramid correctly. Discover which foods go in which food groups, and learn about the concept of discretionary calories. Win extra points by choosing a variety of fruits, whole grains, low fat dairies and green vegetables.
