The Great Ball Court of Xichen Itza measures 545 feet long by 225 feet wide overall. While the floor of the ballcourt has now all but grown over with grass, a few patches remain where we can still see the original tile floor. While little is known for certain about the Mayans great, ceremonial ball game, as no one has seen it in person, the Mayans left us many clues as to the rules of the game in the carvings on the walls of the ballcourt. It is believed that the game was played with a heavy, rubber ball, much like a modern medicine ball. The ball could not be handled by a player's hands, and had to be kicked through the large stone rings near the tops of the walls of the opposite sides of the ballcourt.
