The dispenser 120 further comprises reader 128 disposed in the housing 121 such that a player is enabled to present a ticket thereto for reading a prize identifier disposed on the ticket. The reader 128 is provided, for example, as a bar code scanner for scanning a linear or matrix barcode but is not limited thereto. Optionally, the reader 128 is provided in a separate housing and connected to
.
slip indicative of the prize for redemption. Alternatively, a cash dispenser is provided for paying the prize in cash or a combination of both. Figures 2a and 2b illustrate a preferred lottery ticket 200 for use with the dispenser 120. The lottery ticket 200 comprises a sheet type body such as, for example, a semi-rigid sheet of paper, cardboard, or boxboard. The ticket activation identifier 230 is printed on the front 204 of the ticket 200 in the form of, for example, a linear barcode, or a matrix barcode. Preferably, the ticket activation identifier is uniquely related to the lottery ticket such that each lottery ticket of the plurality of lottery tickets has a unique identifier with data indicative thereof being stored in the trusted database 108. The lottery ticket 200 further comprises play area 218 disposed on the back 212 of the ticket 200 in a concealed fashion together with the prize identifier 217 which is provided in the form of, for example, a linear barcode, or a matrix barcode. Optionally, at least a portion of the identifiers 217 and 230 is encoded using, for example, an error correcting code such as a Reed Salomon code to provide an indication that the identifier has been corrupted and/or to retrieve the identifier in case the barcode has been damaged. The play area 218 and the prize identifier 217 are revealed by the player opening break-open tabs 220A to 220E.
Referring to Figures 3a and 3b, a method for providing an instant lottery game having a varying prize according to a preferred embodiment of the invention is provided. At 10, a plurality of lottery tickets associated with an instant lottery game is provided. Each lottery ticket has a unique ticket identifier related to ticket data stored in the trusted database 108 and a prize identifier related to prize data stored in the trusted database. The display 126A provides potential players with information regarding the available tickets, i.e. instant lottery games. Furthermore, the display 126A provides - 12 - information regarding varying winning opportunities such as, for example, real time information regarding rolling jackpots based on the accumulated jackpot potential of the network of ticket dispensers, which is provided by the trusted server 102 via the computer network 1 10. The player then selects the instant lottery game and the number of tickets to be purchased - 14 - using the user interface 126. After being prompted the player makes the payment - 16 - using the payment device 132 and the user interface 126. After confirmation of the payment, the release mechanism 138 releases - 18 - an un-activated ticket 200 from the
co r men . ea sca - - and sends - 22- data indicative of the ticket activation identifier 230 to the processor 104 of the trusted server computer 102 in a secure fashion for activation. Using the processor 104, the data indicative of the ticket identifier are compared - 24 - with respective ticket data stored in the trusted database 108 and if the comparison is indicative of a match activation data indicative of activation of the lottery ticket are determined. Preferably, the activation data relate the ticket to prize data stored in the trusted database 108. After determination of the activation data, an identifier indicative of successful activation is sent to the release mechanism 138 via processor 122 for initiating dispensing of the activated ticket and, preferably, the respective ticket data in the trusted database 108 are marked as activated or erased.
Preferably, prior performing an activation process - using the processor 104 based on the data indicative of the ticket activation identifier 230 received from the processor 122 of the dispenser 120 - the ticket has no prize value associated therewith. For example, prior the activation process the prize identifier 217 is associated with a zero value, as illustrated in Figure 4a, and the association of the "yet to be revealed" prize identifier 217 with the prize value is then determined during the activation process resulting, for example, in a prize value, a factor indicative of a percentage of the jackpot or a combination of both, as illustrated in Figure 4b. For example, the two identifiers when combined result in a number referring to a memory address with a predetermined prize value or factor stored therein. Optionally, data indicative of a second chance opportunity are determined. Non-winning tickets remain associated with a zero value.
Alternatively, non-winning tickets are supplied without the prize identifier.
Optionally, the processor 104 determines audit trail data in dependence upon the received ticket activation data to determine, for example, royalties payable to the retailer based on the number of sold tickets.
After successful activation, the ticket is dispensed to the player - 26. Optionally, if the activation is unsuccessful, for example, because a damaged ticket identifier could not be read, the release mechanism 138 transfers the un-activated ticket to a holding compartment, releases another ticket from the storage compartment for activation, and provides an error message to the processor 122
or p processor o e rus e server compu er .
After the player has opened the ticket and the game area 218 revealed that the ticket is a winning ticket or has a second chance opportunity, the player scans the prize identifier 217 using the reader 128. The processor 122 then provides - 28 - data indicative of the prize identifier 217 of the lottery ticket to the trusted processor 104. At 30, the processor 104 determines data indicative of the prize associated with the lottery ticket in dependence upon the data indicative of the prize identifier and the prize data; provides the data indicative of the prize associated with the lottery ticket to the processor 122 for display and, optionally, printing a validation slip; and determines new prize data in dependence upon the prize identifier and the prize data. For example, the accumulated jackpot is increased or decreased, depending on whether the ticket was a winner or not. The new prize data are then provided to the dispenser 120 and displayed - 32 - using the display 126A. Preferably, some tickets - in particular, some non-winning tickets - have a second chance opportunity associated therewith in order to further increase players' interest in the instant lottery game. Such tickets have, for example, instructions printed in the concealed game area 218 instructing the player that the ticket is not an instant winner but a second chance opportunity is available at the ticket dispenser 120. Preferably, the second chance opportunity is implemented in the step 30 of the method described herein above and as illustrated in Figure 3b. At 30.1, the player scans the prize identifier indicative of a second chance opportunity which activates the second chance opportunity. There are various options for implementing the second chance opportunity. In a first option - 30.2 - data indicative of a second chance opportunity prize associated with the ticket are determined. For example, using the processor 104 a mathematical algorithm determines if the ticket is a winner at that instant in a random or pseudo-random fashion. Alternatively, the processor 104 activates - 30.3 - a second chance opportunity game which is performed - 30.4 - in communication with processor 122 and user interface 126. The second chance opportunity game is, for example, a skill based game, a probability game, or a combination thereof. In dependence upon the outcome of the second chance opportunity game data indicative of a second chance opportunity prize are then determined - 30.5 - and provided to the ticket dispenser for display and/or print of a validation slip. Finally, new prize data are
e e i ence upon e a a n ca ve o a secon c ance ορ . β prize data - 30.6 - and provided for display.
As is evident, while method for providing an instant lottery game having a varying prize is preferably implemented using the system 100 with the instant lottery ticket dispenser 120 it is not limited thereto. The method is implementable, for example, using conventional lottery kiosks with each kiosk communicating with a trusted central unit.
The present invention has been described herein with regard to preferred embodiments. However, it will be obvious to persons skilled in the art that a number of variations and modifications can be made without departing from the scope of the invention as described herein.
