Abstract

In order to provide a progressive gaming system with greater speed, flexibility and reliability a communication unit is used to control the information transmitted between a group of gaming machines and a progressive controller. The communication unit collects coin-in information from each of the gaming machines and transmits this information to the progressive controller in response to periodic poll signal signals from the progressive controller.

Claims

1. A progressive system comprising:

a plurality of gaming machines;

a progressive controller;

a communication unit operative connected for bi-directional communication with said progressive controller and directly connected for bi-directional communication with each of said gaming machines utilizing a plurality of communication lines such that each of said gaming machines is connected to said communication unit in parallel, and which includes control means having a computer and a data memory for storing an accumulation of coin-in information from more than one of said gaming machines;

for transmitting said accumulation of coin-in information and jackpot hit data from said gaming machines to said progressive controller;

for transmitting jackpot value data from said progressive controller to said gaming machines and for broadcasting simultaneously a plurality of jackpot display values to each of said gaming machines over each of said communication lines.

2. The system of claim 1 wherein said gaming machines include payout means for paying out at least one jackpot in response to said jackpot value data.

3. The system of claim 1 wherein said gaming machines are video poker machines and include display means for displaying simultaneously at least five of said jackpot display values which correspond to winning poker hands.

4. The system of claim 1 wherein said control means includes inhibit means responsive to a predetermined jackpot hit data signal for inhibiting the operation of all of said gaming machines.

5. The system of claim 1 wherein said communication unit receives a coin-in signal from each of said gaming machines and said control means responds to a poll signal from said progressive controller to transmit said coin-in information to said progressive controller which represents a set of said coin-in signals of a predetermined time.

6. The system of claim 1 wherein said control means includes means to receive a release signal from said gaming machines indicating that a manual jackpot has been paid for one of said gaming machines.

7. The system of claim 6 wherein said control means include means to transmit said release signal to said progressive controller.

8. The system of claim 1 wherein said control means includes acknowledgment means for insuring said jackpot value data is received correctly by said gaming machines.

9. The system of claim 1 wherein said control means responds to a poll signal from said progressive controller by selectively transmitting to said progressive controller said coin-in information or said jackpot hit data.

10. The system of claim 1 wherein said control means in response to a poll message from said progressive controller transmits a summation of said coin-in information from more than one of said gaming machines from said data memory to said progressive controller.

11. The system of claim 1 wherein said control means after receiving a signal representing said jackpot hit data from one of said gaming machines transmits an identification of that gaming machine to said progressive controller.

12. The system of claim 11 wherein said identification is transmitted by said control means in response to a polling signal from said progressive controller.

13. The system of claim 1 wherein said gaming machines transmit a release signal to said control means after a jackpot has ben released at one of said gaming machines and said control means transmits a release message to said progressive controller after receiving said release signals from the gaming machine.

14. The system of claim 13 wherein said release message includes an identification of said gaming machine that generated said release signal.

15. The system of claim 1 wherein said progressive controller transmits a lockup instruction to said control means in response to said jackpot hit data and said control means transmits a lockup signal to one of said gaming machines in response to said lockup instruction.

16. The system of claim 15 wherein said control means responds to a poll signal from said progressive controller by transmitting an acknowledgement signal to said progressive controller indicating whether or not said lockup instruction has been executed.

17. The system of claim 1 wherein each of said gaming machines transmits an ID message identifying itself to said control means when the progressive communication system is powered up.

18. The system of claim 1 wherein said coin-in information includes the number of coins bet for games played on more than one of said gaming machines an wherein said control means stores a summation of said coin-in information from said gaming machines in said data memory and wherein said coin-in information transmitted to said progressive controller includes said summation.

19. The system of claim 1 wherein said gaming machines include jackpot means for displaying at least 5 jackpots and wherein said jackpot hit data includes an indication of the one of said jackpots generated by the machine.

20. The system of claim 1 wherein said communication unit includes RS232 interface connected to said gaming machines and a RS422 interface connected to said progressive controller.

21. The system of claim 1 wherein said communication unit is connected to each of said gaming machines by:

a pair of data lines;

an enable line for transmitting enable signals from said communication unit to said gaming machines; and

a connect line for indicting the presence of each of said gaming machines to said communication unit.

22. The system of claim 21 wherein said communication unit includes means to transmit a lock-up signal to said gaming machines over said enable line.

23. The system of claim 21 wherein said communication unit includes means for detecting a fault in said progressive controller and for transmitting a disable signal to said gaming machines in response to said fault detecting means over said enable line.

24. The system of claim 21 wherein said communication unit includes means to detect a fault in communication between said progressive controller and said communication unit and to transmit a disable signal over said enable line to said gaming machines in response to said fault detection.

25. The system of claim 21 wherein each of said gaming machines transmits a signal to said communication unit over said connect line indicating that the game machine is connected to said communication unit.

26. The system of claim 25 wherein each of said gaming machines transmit a game identification code to said communication unit over one of said data lines.

27. The system of claim 21 wherein a coin-in signal, said jackpot hit data and game machine identification signal are transmitted to said communication unit over first of said data lines by said gaming machines;

said jackpot value data is transmitted to said gaming machines over a second of said data lines from said communication unit;

a lockup signal is transmitted to is gaming machines over said enable line from said communication unit and a connect signal is transmitted over said connect line from said gaming machines to said communication unit.

28. The system of claim 27 wherein each of said gaming machines transmit an identification code to said communication unit when the system is powered up.

29. The system of claim 1 wherein said jackpot hit data transmitted to said communication unit from said gaming machine indicates that a particular jackpot has been hit and includes a portion identifying the particular gaming machine where the jackpot was hit and said communication unit transmits, in response to said jackpot hit data, as part of said jackpot value data, a current value message representing the current value of that jackpot to said particular gaming machine.

30. The system of claim 29 wherein said particular gaming machine transmits an acknowledgement signal to said communication unit indicating that said current value message was properly received.

31. The system of claim 1 wherein said jackpot value data includes a portion indicating which one of plurality of jackpot has been hit and a portion indicating the current value of said one of said jackpots.
