Claim:
1. A lottery ring comprising: a first ring having a plurality of accommodating units along its circumference in a rotation direction, each accommodating unit configured to accommodate a physical lottery medium; a second ring parallel with and atop the first ring, both rings being concentrically arranged along a central axis to form a layer and perform concentric movement relative to each other; a plurality of information providing units arranged to correspond with the plurality of accommodating units along the layer, each information providing unit configured to provide predetermined information along the second ring; a switching device comprising a plurality of lifting units spaced radially from the central axis and arranged in symmetrical positions; and a constraining device provided in the second ring so as to correspond to the plurality of lifting units and engaged and disengaged by the lifting units to raise and lower the constraining device in communication with the layer that operates between a constraint state wherein the constraining device is lowered relative to the first ring for constraining the first ring and the second ring such that the first ring and the second ring integrally rotate together about the center axis and a release state wherein the constraining device is raised relative to the first ring for releasing the constraint state such that the first ring and the second ring relatively rotate independently of each other, where the physical lottery medium moves along the rotation direction and into an accommodating unit on the first ring such that the lottery medium interacts with at least one information providing unit and provides corresponding predetermined information; and a control unit including a processor to communicate with the lifting units and to determine whether a predetermined condition has been satisfied to activate the lifting units.
