Modified ceramic disks have been recovered from historic-era sites across the Americas. Small unperforated disks are commonly interpreted as gaming pieces and larger perforated disks are often classified as spindle whorls.

These gaming pieces facilitated the social cohesion of Native people living in the large, multiethnic Indigenous communities that formed around Spanish colonial missions and later Mexican-era ranchos
