Roulette number bracket indicator

Abstract

A roulette number bracket indicator is provided to indicate the numbers located to either side or any desired distance from the number sought. The roulette number bracket indicator is in the form of a slide rule composed of two or more interacting members. Rotation or movement of one member relative to the other members selectively provides the desired information. The upper members have a cutout or cutouts spaced uniformly along a portion of the member. Indicia are printed on the upper member adjacent the cutout. A lower member has the layout of a roulette wheel printed thereon. The position of the roulette wheel pattern is such that alignment shows a bracketed portion of the numbers as on roulette wheel.
