ABSTRACT:

BACKGROUND
The present invention relates generally to remote gaming systems, and more particularly, to an off-line system for playing games of chance, including instant-type lottery games typically embodied in a ticket having multiple chances which represent a single predetermined outcome offered by a managing authority are rendered on a gaming computer as an “electronic ticket,” such as, for example, a dedicated hand-held device or programmed general personal computer. In addition, the present invention provides for playing games of skill on such a device. In a lottery application, the system enables a player to play instant-type tickets on the game computer with the same convenience as typical paper scratch-off tickets at any location without the gaming computer ever having to be physically or electronically connected to a lottery system network during play, thereby providing enhanced play value for the player and greater revenues for the managing authority.
In the case of typical paper instant tickets, a computer generates a randomized prize data stream comprised of a finite series of win/lose outcomes. Each outcome is assigned to a lottery ticket, and each ticket contains one or more game chances which yield the assigned outcome. The player cannot change the ticket outcome, he or she merely scratches off certain areas of the ticket in accordance with the rules of the game to reveal the outcome. The ticket contains indicia which provide the player with a means to determine win/lose results or prize status, and the type of prize (e.g., cash or a free ticket). The aggregate of all winning outcomes in any randomized prize data stream is a predetermined percentage payout of the total revenues that would be generated by the sale of all of the tickets incorporating that particular randomized prize data stream.
In one specific embodiment of prior art paper instant ticket systems, ticket outcomes are generated by the computer tapes that control printing of the tickets. These tapes contain each outcome for any given run of tickets. The outcomes are created using essentially similar methods throughout the industry. For example, a run of 24 million tickets that has 120 top payouts of $10,000 and a payout percentage of 55%, may be broken up into 100 blocks of 240,000 tickets each. The $10,000 winners will be distributed as evenly as possible among the 100 blocks, so there will be at least one top prize in each block, with 20 blocks having two top prizes. The 80 blocks without the two top prizes will be compensated by offering more low and mid-tier prizes, so that the payout percentage is exactly 55% for each 240,000 ticket block. Each of these 240,000 ticket blocks is broken up into books of tickets, typically 200 to 400 tickets per book. Tickets are delivered to retailers in book units, where each ticket has two identifying numbers, a book/ticket number and a validation number. The book/ticket number is usually printed on the back of the ticket. An exemplary book ticket number is “089-46127-234.” The “089” identifies the game, in this case a State X $3 “Win for Life.” The “46127” is the book number, which in this case means that this ticket is from book number 46127. The “234” identifies this ticket as the 234th ticket from this book. The validation number is printed under the latex surface on the front of the ticket. This number is the key to determining whether or not the ticket is a winner. When a winning ticket is presented for prize redemption, the retailer types this number into an agent terminal, from which access to a central database of instant tickets provided by the ticket printer is obtained to search the record of outcomes for that run of tickets. This database resides in a separate computer at the main computer center of the online service provider (such as GTECH).
To prevent fraud, the validation number cannot be seen without scratching off the latex covering material. If the validation number were visible without requiring that the latex be removed first, retailers could check whether or not each ticket was a winner, and then keep winning tickets for themselves, selling only the losing tickets to customers. In this connection, the validation number is typically comprised of nine (9) digits. An illustrative validation number for the above “Win for Life” ticket is: 71069-7041. This number singularly identifies this ticket from the millions of tickets that are printed for that game. It is important to note that this number is encoded and not in sequential order. If the latter was the case, retailers could buy one ticket for themselves and check its validation number. They could then enter the next ten validation numbers into the online system to determine whether any were winners. Again, customers might be sold the losing tickets while the retailer kept the winners. Encryption prevents this, because knowing one validation number provides the retailer with no information about the next number.
Some lotteries place restrictions on the distribution of outcomes, including limits on the number of high tier winners per book; how many consecutive non-winning tickets Y% of the time; and the maximum number of non-winning tickets per row. In arranging the lottery, the authority decides how many tickets are to be sold, the payback percentage of the game as a whole, and what prizes will be awarded and the frequency of winning tickets among the total number of tickets. For example, if the lottery wanted to sell a total of 20 tickets and have a payout percentage for the game of 50%, they might need to pay $10 total for the game. This might consist of one $5 winner, one $2 winner, and three $1 winners and may be represented as: 5, 2, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0. Note that the process so far has been completely deterministic. There is no randomness at all. Of course the lottery does not want to have the first five tickets sold to be winners, so it randomizes the order of the tickets. The resulting sequence might look like the following: 0, 0, 0, 0, 0, 1, 0, 2, 0, 0, 5, 0, 0, 0, 0, 1, 0, 0, 0, 1. As tickets are requested by players, they are removed from the sequence of outcomes. From the above set of outcomes, a player requesting four tickets might buy four losers—0, 0, 0, 0. If the next player requested three tickets, he or she may get 0, 1, 0. The next three tickets sold might be 2, 0, 0. This process continues until the entire sequence of outcomes is exhausted. Of course the computer can also pull outcome requests from the game sequence at random, so that a request for three outcomes could get the outcomes in location 5, 8, and 11 (which might correspond to 0, 2, 5). These outcomes would then be eliminated from the game sequence so that the next player cannot get the same sequence.
The lottery ticket may also contain a batch number that is typically visible on the ticket in the form of a bar code. All tickets in a given master carton are part of the same ticket lot and are sold at the same price point. Each master carton is labeled with a unique master carton serial number which is tracked by a central management computer associated with the managing authority. The central management computer also stores every ticket serial number and the associated outcome for that ticket. When the instant tickets are to be sold to customers, the lottery retailer communicates the master carton serial number via his on-line agent terminal to the central management computer and thereby activates all of the paper instant tickets in each master carton. This action activates all of the ticket serial numbers in that master carton, and typically causes the lottery retailer's lottery bank account to be automatically debited for the wholesale cost of that master carton within a specified time period.
To redeem a winning paper lottery ticket, the player presents the same to a redeeming agent, either at a lottery retailer or lottery office, or mails the ticket in for redemption. To effectuate the redemption process, the redeeming agent scans the bar code on the ticket which repres
