Ball games of various kinds were popular in all of the ancient Mesoamerican civilizations, including that of the ancient Incas. The most popular of them was known as tlachtli or pok-to-pok.
Known as the first organized sport in human history, evidence dates it back 3,500 years. Rules of the game varied from city to city, with virtually every city having a ball court. The game was played with heavy latex balls made from the rubber trees that grew in the area. The game was played for the ultimate stake; the losers were put to death on the ball court as a human sacrifice.
