A high impact game ball with a core structure founded on a spherical member, a spherical casing concentrically disposed relative to the spherical member, at least one surface deviation disposed relative to the spherical member of the core structure, and at least one corresponding surface deviation disposed relative to the spherical casing in a mating relationship with the at least one surface deviation of the spherical member. A switching arrangement can be embedded in the spherical member for causing a response to be exhibited based on the occurrence of an activation condition, such as an impact or a remote activation signal. A plurality of positioning stays can project from the spherical member to ensure a concentric relationship relative to the spherical casing.
