The Ollamaliztli (ōllamalīztli, oːlːamaˈlistɬi, pitz) was a sport with ritual associations played since at least 1650 BC by the pre-Columbian people of Ancient Mesoamerica. The sport had different versions in different places during the millennia, and a modernized version of the game, ulama, is still played by the indigenous populations in some places. The rules of the Mesoamerican ballgame are not known, but judging from its descendant, ulama, they were probably similar to racquetball, where the aim is to keep the ball in play. The stone ballcourt goals are a late addition to the game. In the most common theory of the game, the players struck the ball with their hips, although some versions allowed the use of forearms, rackets, bats, or handstones. The ball was made of solid rubber; its size differed greatly over time or according to the version of the game, but it could weigh as much as . The Mesoamerican ballgame had important ritual aspects, and major formal ballgames were held as ritual events. Late in the history of the game, some cultures occasionally seem to have combined competitions with religious human sacrifice. The sport was also played casually for recreation by children and may have been played by women as well. Pre-Columbian ballcourts have been found throughout Mesoamerica, as for example at Copán, as far south as modern Nicaragua, and possibly as far north as what is now the U.S. state of Arizona. These ballcourts vary considerably in size, but all have long narrow alleys with slanted side-walls against which the balls could bounce in. The Mesoamerican ballgame is known by a wide variety of names. In English, it is often called pok-ta-pok (or pok-a-tok). This term originates from a 1932 article by Danish archaeologist Frans Blom, who adapted it from the Yucatec Maya word pokolpok. In Nahuatl, the language of the Aztecs, it was called ōllamaliztli (oːlːamaˈlistɬi) or tlachtli (ˈtɬatʃtɬi). In Classical Maya, it was known as pitz.
