An independent browser reimplementation of the playground game tetherball, with an exact simulation of the wrapping-rope constraint. Tetherball is a folk game in the public domain, described by Jessie H. Bancroft in 1909; no code or asset comes from any existing product. Runs entirely client-side: no model, no credits.

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
