Abstract

A slot machine has inner and outer coaxial overlying reels. Each reel is formed with symbols on its transparent outer circumferential frame. The inner and outer reels are rotated independently by motors. The outer reel has a transparent outer circumferential frame to allow a player to see symbols on the inner reels. A combined symbol of superposed inner and outer reel symbols is produced.

Claims

1. A slot machine having a plurality of rotatable reels comprising an outer reel and an inner reel disposed coaxially within said outer reel;

said outer reel having a transparent outer circumferential frame, a plurality of symbols being disposed on said transparent outer circumference frame;

said inner reel having a plurality of symbols formed at an equal pitch on an outer circumferential frame of said inner reel; and

means to rotate said reels simultaneously in opposite directions.

2. A slot machine having a plurality of rotatable reels comprising an outer reel and an inner reel disposed coaxially within said outer reel;

said outer reel having a transparent outer circumferential frame, a plurality of symbols being disposed on said transparent outer circumference frame;

said inner reel having a plurality of symbols formed at an equal pitch on an outer circumferential frame of said inner reel;

wherein said symbols of one of said outer and inner reels include "spade", "heart", "diamond" and "club"0 symbols, and said symbols of the other of said outer and inner reels include alphanumeric symbols "A" to "10" and "J", "Q" and "K".

3. A slot machine having a plurality of rotatable reels comprising an outer reel and an inner reel disposed coaxially within said outer reel;

said outer reel having a transparent outer circumferential frame, a plurality of symbols being disposed on said transparent outer circumference frame;

said inner reel having a plurality of symbols formed at an equal pitch on an outer circumferential frame of said inner reel;

wherein said symbols of said outer and inner reels are equally peripherally spaced apart about said reels, a said symbol on one of said outer and inner reels comprising two identical spaced markings and a said symbol on the other of said outer and inner reels comprising an identical marking which, when said reels are stopped in one position, it is disposed between said two spaced markings in the line of sight of a user of said machine.
