  • Patent number: 6017032
    Abstract: A lottery game includes two or more different denominational levels for game tickets, i.e., two or more groups of tickets with tickets in each group being priced differently from tickets in the other groups. All tickets in any one group are priced identically to one another. Wagers received from each ticket group are placed in a corresponding jackpot pool according to the denominational level or amount of the tickets sold for that pool. All wagers for each denomination are processed by a single central controlling authority, with wagers being distributed to each separate pool according to the corresponding wager denomination. Thus, the present game may provide a series of different and separate jackpot pools corresponding to each ticket price or denominational level. Jackpots or prizes are awarded from each pool to the winning bettor holding a ticket corresponding to that denominational level and jackpot.
