Hyperball vs. Hypersphere — What's the Difference?

Hyperball is a clone of the 1986 arcade game Arkanoid created for the Acorn Electron and BBC Micro. It was released as part of the compilation Play It Again Sam 13 in 1990.

Any of a set of objects resulting from the generalization of a two-dimensional circle and a three-dimensional sphere to n dimensions. In n-dimensional space, a hypersphere is the set of all points that are a given distance, called the radius, from a given point, called the center.

(geometry) The set of all points that make a hypersphere.

(geometry) The set of all points in a given hyperspace that are at a given distance from a given point; a generalization of a sphere in four or more dimensions

(sports) A zorb; the act of zorbing, entering a zorbing ball, strapping into a harness, and rolling down a hill

A mathematical object existing in more than three dimensions, analogous to the sphere in that all points on the surface are equidistant from the central point; a generalization of a sphere in more than three dimensions.
