4. A progressive gaming system having gaming terminals for use by players and said progressive gaming system also having a central system for making determinations of whether a progressive prize has been won comprising:
-
a first processor coupled to a first plurality of gaming terminals, said first processor configured to communicate first information to said central system, said first information including at least a magnitude of a contribution from said first plurality of gaming terminals towards said progressive prize; a second processor coupled to a second plurality of gaming terminals, said second processor configured to communicate second information to said central system, said second information including at least a magnitude of a contribution from said second plurality of gaming terminals towards said progressive prize; wherein said central system is configured to make at least one said determination in response to a cumulative amount of said contribution by one of said first plurality of gaming terminals and said second plurality of gaming terminals exceeding a predetermined threshold. - View Dependent Claims (5, 6, 7, 8, 9)

10. Apparatus for a progressive gaming system comprising:
-
first and second pluralities of gaming terminals in first and second locations, each gaming terminal configured for receiving wagers from players, and having a card reader for reading a card which identifies a player at said gaming terminal; first and second computer network systems coupled to said first and second pluralities of gaming terminals respectively; each network system receiving from said coupled plurality of gaming terminals information related to the amount of wagers placed on said gaming terminals by said players and information indicating the identity of the players in accordance with the identities indicated by said card readers; first and second computers coupled to said first and second networks and having a communication link to a central computer system; said first and second computers configured to communicate to said central system, the magnitude of a contribution from said first and second pluralities of gaming terminals respectively towards a progressive prize; said central computer system configured to periodically poll said first and second computers, wherein said first and second computers, in response to said polling, transmit to said central computer system an indication of said contribution; said central computer system accumulating said contributions in first and second accounts for said first and second pluralities of gaming devices until any said account reaches a threshold amount whereupon said central system; subtracts the threshold amount from said account; adds said threshold amount to said progressive prize; generates a random number between 1 and a predetermined odds number and; compares said random number to a stored winning number; wherein when said generated random number matches said stored winning number, said central system communicates a win decision to at least one of said first and second computers whose account reaching said threshold was responsible for generation of said random number and; wherein said one computer, in response to receipt of said win decision, generates a signal to notify at least one of said players that said player has won said progressive prize; wherein there is no direct communication between said gaming terminals and said central computer system.
