Lottery game with pari-mutuel payout

Abstract

A multi-group lotto game which allows for groups having differing payout structures and prize percentages. A first group has a pari-mutuel payout structure providing variable prize levels and a fixed cyclical prize percentage and a second group has a fixed prize level and variable prize percentage approaching a target over a statistically long period of time. Prize levels may be calculated in a variety of ways, for example as fixed percentages of prize sales or as a hierarchical cascade of percentages.

       2 . The prize pool of  claim 1 , further comprising a plurality of levels of subordinate prizes, wherein the second member lottery awards a first subordinate prize equal to a fixed percentage of a second subordinate prize.
