Electronic gaming machine and method
First Claim
1. A gaming machine, comprising:
- a payment acceptance device, for accepting payment from a player wishing to use the gaming machine;
a supply of tickets installed inside the gaming machine;
a ticket dispenser for dispensing one ticket at a time from the supply of tickets, wherein each ticket includes indicia imprinted thereon but not readable without removal of an indicia cover, and each ticket further includes a machine-readable ticket identifier uniquely identifying said each ticket;
a memory module in which are electronically stored ticket records corresponding to the tickets in the ticket supply, each ticket record including codes corresponding to the ticket identifier and the indicia imprinted on the ticket;
a ticket reader, for reading the ticket identifier on each ticket before it is dispensed; and
a game controller, responsive to acceptance of payment, for reading a next sequential ticket record from the memory module, comparing the code corresponding to the ticket identifier of the next sequential ticket record with the ticket identifier read by the ticket reader and, if there is a match, actuating the game ticket dispenser to dispense the ticket;
wherein the indicia imprinted on each ticket are not identified from examination of the ticket without removing the indicia cover.

Abstract
A "pull-tab" gaming machine for dispensing game tickets with imprinted symbols or indicia that cannot be viewed without removing a cover strip and cannot be mechanically scanned to reveal the indicia. A ticket supply, such as a continuous roll of tickets, is installed in the machine together with an electronic memory module that contains a ticket record for each ticket in the supply. The memory module is read sequentially to obtain a ticket identifier and ticket indicia data. The ticket identifier from the memory module is compared with a machine-readable identifier encoded onto each physical ticket and, if a match is found, the ticket is dispensed and its indicia data, as obtained from the memory module, are displayed on a screen. Winning combinations of indicia are detected electronically and used to actuate a winner light on the machine. Because the ticket indicia are neither printed nor encoded onto the exterior of the ticket, the locations of winning tickets cannot be determined in advance of ticket purchase.

9. A method of operation of a gaming machine, comprising the steps of:
-
determining whether payment has been made to purchase a gaming ticket from the gaming machine; determining whether a play control has been activated to initiate operation of the gaming machine; when payment has been made and play initiated, reading a next ticket record from an electronic memory module installed in the gaming machine and having ticket records corresponding to tickets in a ticket supply installed in the gaming machine, where each ticket includes a unique ticket identifier wherein each ticket record includes the ticket identifier and indicia that are the same as indicia printed on the ticket; reading a ticket identifier from a next ticket in the ticket supply; comparing the ticket identifier read from the next ticket with the ticket identifier from the next ticket record read from the electronic memory module, to validate the ticket; and if the step of comparing results in a match, dispensing the next ticket from the ticket supply. - View Dependent Claims (10, 11, 12)
