For example, in these embodiments, it may be preferred that only one of the disc-shaped side caps can be released and replaced with a tensile force of 20N. In a preferred embodiment, the first centered extension can engage in the second central recess of the centered ball bearing, wherein the first centered extension of the first disc-shaped side cap has a central recess into which the second centered extension of the second disc-shaped side cap can engage positively and wherein the The first disc-shaped side cap and the centered ball bearings can no longer be detached from each other and wherein the second extension can engage positively in the central recess of the first extension. However, it is particularly preferred that the composite disk-shaped side caps can be released again from one another and also from the flywheel body under the action of force. This is particularly preferred if, for example, the flywheel body or one or both of the disk-shaped side caps of the rotatable game body are to be exchanged. In an exemplary embodiment, various flywheels and various disc-shaped side caps are provided which may be assembled together by a user in any combination.

Thus, it is preferred that the second centered extension (P2) of the second disc-shaped side cap (K2) engages in the first centered extension (P1) of the first disc-shaped side cap (K1) or the second centered extension (P2) of the second disc-shaped side cap (K2).
