][2] Although there is a tremendous variation in size, in general all ballcourts are the same shape: a long narrow alley flanked by two walls with horizontal, vertical, and sloping faces.
[7] The ballgame was initially thought to be originated in the coastal lowlands, yet a ballcourt was discovered at Etlatongo in the mountains of southern Mexico, dating to 1374 BCE.
[9] At Cantona, for example, the extraordinary number of ballcourts is likely due to the many and diverse cultures residing there under a relatively weak state.
[13] The earliest ballcourts were doubtless temporary marked off areas of compacted soil much like those used to play the modern ulama game, the Mesoamerican ballgame's descendant.
Paso de la Amada, Soconusco, along the Pacific coast boasts the oldest ballcourt yet identified, dated to approximately 1400 BC.
By the Early Classic, ballcourt designs began to feature an additional pair of mounds set some distance beyond the ends of the alley as if to keep errant balls from rolling too far away.
Unlike the compacted earth of the playing alley, the side walls of the formal ballcourts were lined with stone blocks.
Most prominent ballcourts were part of their town or city's central monumental precinct and as such they share the orientation of pyramids and other structures there.
[21] As shown on Aztec codices, court markers were also used on many ballcourts to establish the dividing line between teams – one set into the playing alley floor at exact mid-court, the other two placed against each side wall.
Two ancient ceramic ballcourt models recovered from western Mexico show the three markers placed length-wise along the court: one (again) at exact mid-court with the remaining pair set midway between the walls at either end of the playing alley.
[25] Conversely, Maya staircases will occasionally feature reliefs of ballgame scenes or ballgame-related glyphs on their risers.
