Teckball is a sport that originated on Earth in the late 20th century. It was invented by an ancestor of Stephen Tecklenberg, and though Teckball was only sporadically popular in its time, it survived World War III and experienced a resurgence among the early human colonies in the 22nd century. (Star Trek: Pendragon) Tecklenberg and Sinclair often hyperbolically described the sport as "a fusion of soccer, rugby, American football, basketball, hockey, Parrises squares, Velocity, Kal-toh, Parcheesi, poker and tiddlywinks."
