Safe and novel hand grip systems for manually gripping and spinning gaming wheels or rotatable gaming apparatus are improved by including a lightweight, spoked-frame, rotating-rim gaming wheel that may comprise “snap-fitting” and/or modular electronic-plug-in game play wedge pieces. As well, the improvements also encompass inclusion of a novel optional stationary gaming wheel frame in conjunction with the above said rotating hand grip systems, that itself may include several embodiments and modifications.
