Abstract

A gaming apparatus which comprises a slot machine capable of accepting either paper currency, preprinted coupons, or cash out slips. The slot machine also includes a printer that prints and dispenses cash out slips which include a bar code representing a unique identification that provides the amount of “winnings”. The cash out slips can be scanned into a separate currency dispenser at a Cashier'"'"'s Station for receiving currency, either from the dispenser or from an attendant. A central processing unit (CPU) generates the unique codes for regulating the game to be played, the wager limits of the game and the validity of the free play coupons or the cash out tickets. The above gaming system avoids having to use coins or tokens in the operation of slot machines.

Claims

1. A method, comprising:

storing in a host computer data relating to a ticket printed by a printing apparatus associated with a first casino slot machine, said ticket having a monetary value and having an image of a bar code printed thereon and an image of said monetary value printed thereon;

receiving data at said host computer from an image reading device associated with a second casino slot machine different than said first casino slot machine, said received data having been generated in response to inspection of said ticket that was printed by said printing apparatus associated with said first casino slot machine by said image reading device associated with said second casino slot machine;

determining whether credit should be authorized by making a comparison of data relating to said ticket with data stored in a memory of said host computer; and

transmitting a signal from said host computer to said second casino slot machine, if credit should be authorized as determined by said host computer, to authorize credit to allow play of said second casino slot machine.

2. A method as defined in claim 1 wherein said host computer determines whether credit should be authorized by determining whether a monetary amount associated with said ticket has previously been paid.

3. A method as defined in claim 1 wherein said host computer determines whether credit should be authorized based on a control number associated with said ticket.

4. A method as defined in claim 1 wherein said host computer determines whether credit should be authorized based upon a control number randomly assigned to said ticket.

5. A method as defined in claim 1 wherein said bar code image represents a monetary amount and wherein said method comprises storing data representing said monetary amount in said host computer.

6. A method as defined in claim 1 wherein said bar code image represents a monetary cash out value and wherein said method comprises storing data representing said monetary cash out value in said host computer.

7. A method as defined in claim 1 additionally comprising receiving player identification data at said host computer from said first casino slot machine.

8. A host computer, comprising:

a central processing unit;

a memory; and

a computer program,

said host computer being programmed to store data relating to a ticket printed by a printing apparatus associated with a first casino slot machine, when said host computer is operatively coupled to said printing apparatus, said ticket having an image of a bar code printed thereon and an image of a monetary value printed thereon,

said host computer being programmed to receive data from an image reading device associated with a second casino slot machine different than said first casino slot machine, when said host computer is operatively coupled to said image reading device, said received data having been generated in response to inspection by said image reading device of said ticket that was printed by said printing apparatus associated with said first casino slot machine,

said host computer being programmed to determine whether credit should be authorized by making a comparison of data relating to said ticket with said stored data, and

said host computer being programmed to transmit, when said host computer is operatively coupled to said second casino slot machine, a signal to said second casino slot machine, if credit should be authorized as determined by said host computer, to authorize credit to allow play of said second casino slot machine.

9. A host computer as defined in claim 8 wherein said host computer is programmed to determine whether credit should be authorized by determining whether a monetary amount associated with said ticket has previously been paid.

10. A host computer as defined in claim 8 wherein said host computer is programmed to determine whether credit should be authorized based on a control number associated with said ticket.

11. A host computer as defined in claim 8 wherein said host computer is programmed to determine whether credit should be authorized based on a control number randomly assigned to said ticket.

12. A host computer as defined in claim 8 wherein said bar code image represents a monetary amount and wherein said host computer is programmed to store data representing said monetary amount.

13. A host computer as defined in claim 8 wherein said bar code image represents a monetary cash out value and wherein said host computer is programmed to store data representing said monetary cash out value.

14. A host computer as defined in claim 8 wherein said host computer is additionally programmed to receive player identification data from said first casino slot machine when said host computer is operatively coupled to said first casino slot machine.

15. A gaming system comprising:

a host computer as defined in claim 8;

a first casino slot machine operatively coupled to said host computer; and

a second casino slot machine operatively coupled to said host computer.

16. A gaming system comprising:

a host computer as defined in claim 8;

a first coinless casino slot machine in which no coins are inserted, said first coinless casino slot machine being operatively coupled to said host computer; and

a second coinless casino slot machine in which no coins are inserted, said second coinless casino slot machine being operatively coupled to said host computer.
