This invention relates to gaming systems, and more particularly relates to processing and communication of data related to progressive jackpots calculated by such systems.
A large gaming casino typically employs thousands of gaming machines that can be operated simultaneously. These gaming machines can be used to simultaneously play multiple games using multiple progressive jackpots as rewards. For example, a first group of users simultaneously may be playing a first group of gaming machines employing a first progressive jackpot at multiple gaming facilities, while a second group of users simultaneously may be playing a second group of gaming machines employing a second progressive jackpot at the multiple facilities. Typically, the gaming machines include jackpot meters that generate jackpot data used to calculate the progressive jackpots. The jackpot data is transmitted from each gaming machine and each gaming location to a progressive jackpot server at a remote location, which may receive a large amount of data, including jackpot data, during a short time period. Experience has shown that the data may be lost due to network congestion or to inadequate processing speed to accommodate the large volume of data. In addition, in the past, each progressive jackpot has required a separate link and separate communication line from a gaming facility to the remote location. This results in addition expense to install and maintain the multiple links and communication lines.
Gaming facilities in different locations are increasingly owned by a single legal entity, such as a corporation. There is expected to be a demand for a first group of progressive jackpots based on play of progressive gaming machines located in many, if not all, facilities owned by a single corporation, and demand for a second group of progressive jackpots based on play of progressive gaming machines located in a single one of the commonly-owned gaming facilities. In addition, there is expected to be a demand for progressive games that enable play of a progressive game on gaming machines owned by multiple corporations at multiple gaming facilities. Providing progressive jackpots for these various arrangements presents problems solved by at least one embodiment of the present invention.
One system for calculating progressive jackpots based on data from multiple gaming facilities is shown in U.S. Pat. No. 5,766,076 (Pease et al, issued Jun. 16, 1998, the “'076 patent”). That system includes a processor 138 that aggregates contributions to a progressive jackpot and maintains a current database of gaming machines 108. Data from processor 138 is sent to a central computer system 106 via modems and a network. Other casinos 165 also are connected to the central computer system 106 via a network. Central system 106 does jackpot calculations based on data received from the casinos. However, there appears to be no teaching or suggestion in the '076 patent for transmitting data for multiple progressive jackpots or links over a single communication network. There also appears to be no teaching or suggestion for accommodating progressive jackpots based on machines owned by different corporations.
Another gaming system for calculating a progressive jackpot also is taught in U.S. Pat. No. 6,203,010 (Jorasch et al., issued Mar. 20, 2001). This patent also appears to contain no teaching or suggestion for transmitting data for multiple progressive jackpots or links over a single communication network. There also appears to be no teaching or suggestion for accommodating progressive jackpots based on machines owned by different corporations.
Another system for handling progressive jackpots is described in U.S. Pat. No. 5,752,882 (Acres et al., issue May 19, 1998). As shown in
U.S. Pat. No. 5,885,158 (Torango et al.) describes a gaming system for multiple progressive games. According to
None of the foregoing patents effectively addresses the problem of reducing the number of communication networks between gaming facilities in different locations that use a common jackpot facility for calculating progressive jackpots played at the gaming facilities, and none addressed the problem of accommodating progressive jackpots based on machines owned by different corporations. The present invention addresses the foregoing problem and provides solutions.

Facilities C1-C4 include casinos located at different locations remote from each other. Casinos C1-C3 are owned or controlled by a common legal entity, such as a first corporation. Casino C4 is owned or controlled by another legal entity, such as a second corporation different from the first corporation.
Each of casinos C1-C4 includes multiple banks of progressive jackpot gaming machines. A bank of gaming machines is a series of machines having some phase of operation in common, such as contributing to one or more common progressive jackpot games.
Central authority 20 calculates multiple progressive jackpot values based on data received from the gaming machines in casinos Cl-C4 via network 30. The sources of data from which the various jackpot values are calculated are summarized in the following
Gaming machine groups GR 2, GR 3, GR 4, GR 6, GR 7, GR 8, GR 10, GR 11, GR 12, GR 14, GR 15, and GR 16 include multiple single banks of gaming machines for which progressive jackpots may be calculated as shown in connection with single bank progressive jackpots JP 23-JP 38.
Preferably, if facilities C1-C4 are located within a single state, all jackpots JP 1-JP 38 are calculated by a single jackpot processor, such as processor 22 (
Any gaming machine that contributes to a jackpot for a single bank (e.g., any of banks JP 23-JP 38) also contributes to at least one of the higher level jackpots. For example, a gaming machine that contributes to JP 23 also contributes to JP 7 of group GR 1, JP 4 of casino Cl, JP 2 of casinos C1-C3 and JP 1. Similarly, a gaming machine that contributes to JP 35 also contributes to JP 19 of group CR 13, JP 3 of casino C4, and JP 1.
The invention is not limited to the levels of jackpots shown in
