Also known as Zim Zam, Tether Tennis or Swingball, this simplest of concepts was a huge seller in its day.
Basically, just a tennis ball attached to a cord connected to a vertical pole with a coil on top, the game has been known since the early 1900s.
One of the earliest formal descriptions of the game appeared in Jessie H. Bancroft’s 1909 book, Games for the Playground, which detailed the rules for “Swingball”.
The modern iteration of Swingball was invented in 1967 in South Africa by Gavin Gormley. The game was introduced to the UK market in 1973, where it rapidly became a staple of backyard family activities.
In the 1970s and 80s, the game was marketed in the United States by Fonas under the name Zim Zam (or Zimm Zamm).
Totem Tennis became the standard branding in Australia and New Zealand.
The British company Mookie Toys has been the primary driver of the product’s development since the early 1990s.
