Pyramid of the Sun follows a simple turn structure; on your turn, you either play cards from your hand or draw two cards, choosing each either from the deck of middle sections or from the deck of edges and pyramid tops. Playing cards allows you to score points or — in some cases — draw an additional card. As the pyramid grows taller, you have an opportunity to score more and more — but the higher the possible score, the fewer spaces you have to play your cards.

If you want to win, you need to be smarter than your opponents. Play your cards right, find the perfect time to use them, and score the most points. Outwit your friends and become the true builder of the Pyramid of the Sun!
