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)
It was also popular among the settlers of the Belle Terre colony, where Steve Tecklenberg was born in the 24th century. Tecklenberg taught the sport as part of his training curriculum at Starfleet Academy. It was popular among the cadets of Nebula Squadron, especially Timothy Sinclair, and remained an unofficial Academy sport even after their graduation.
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."
