Abstract
To make it more difficult for system gamblers to predict their chances of successfully placing their chips, the number ring in roulette equipment is an independent component that rests on the bottom of the bowl and can be angularly displaced from outside against inherent resistance. The ring is re-adjusted from time to time by the casino personnel to contaminate the probabilities.
Claims17
A roulette arrangement comprising:
- a base and a stationary shaft extending up out of said base;
- a bowl rotating on said shaft, said bowl having an interior divided into first and second rings and a center, said first ring being adjacent to an edge of said bowl and being divided into fields marked with numbers, said second ring being positioned lower inside said first ring and separated by radial frets into canoes, each of said canoes being as wide as an associated one of said fields;
- a shallow conical pan concealing said center;
- said first ring being an independent component of components of said bowl and resting on a bottom of said bowl and being angularly displaceable from outside of said roulette arrangement against inherent resistance;
- a rim around a lower surface of said first ring and fitting into a matching recess in said bottom of said bowl and leaving a gap at a level of said recess in the form of a groove extending around an inner surface of said recess, radial bores extend through said rim;
- balls accommodated by said bores and forced into said groove by springs;
- and plugs for maintaining said balls in said bores.

- said first ring being an independent component of components of said bowl and resting on a bottom of said bowl and being angularly displaceable from outside of said roulette arrangement against inherent resistance;
- said first ring being independently movable of other parts of said bowl for limiting the ability of players to estimate their chances of winning by being angularly displaceable through at least one field around the interior of said bowl after having been operative for a time to change an association between said numbers and said canoes.
