1. Field of the Invention
The invention relates generally to a system and method for implementing a lottery game, and more particularly to a lottery game in which supplementary indicia are drawn which are available only to players who have wagered more than the minimum amount required to play the game.
2. Description of the Related Art
Many governments and/or gaming organizations sponsor wagering games known as lotteries. A typical lottery game entails players selecting permutations or combinations of numbers. This is followed by a “draw,” wherein the lottery randomly selects a combination or permutation of numbered balls. Prizes are awarded based on the number of matches between a player's selection and the drawn numbers. The drawn numbers are the well-publicized, and multi-million-dollar-jackpot lotteries are popular throughout the world.
Lotteries have become an important source of income to governments as they shoulder much of the financial burden for education and other programs. However, as governments have grown more dependent on lotteries, it has become a challenge to increase sales, particularly for on-line games, i.e. games in which player-selected indicia are sent through a terminal to a central system and subsequently compared to lottery-selected indicia to determine if the player has won a prize. One approach for invigorating lottery sales for on-line drawing games is to offer games in which the player has the opportunity to make an additional wager beyond the minimum amount required to play the game. This, in turn, requires that the game be structured in such a way that it is readily apparent to the player that the additional wager provides added value. Thus, there is a need for a lottery game in which players who make a minimum wager will often have the experience of concretely seeing that they could have had a better outcome had they made a larger wager.
Briefly describing, the invention teaches a lottery game with a supplemental game. A player plays the lottery game by selecting a set of numbers and can also opt to play the supplemental game. The winning numbers for the lottery game are drawn along with a set of supplemental numbers. The player can win the lottery game by matching his select numbers with the winning numbers for the lottery game. The player can also increase his winning chance by matching his select numbers with the supplemental numbers if he has opted to play the supplemental game.
In one embodiment, the invention comprises a lottery game in which the player selects a plurality of indicia from a set of indicia and also chooses how many of the plurality of indicia to be drawn by the lottery will be compared to the player-selected indicia for the purpose of prize determination, where the amount of the wager and the magnitude of the prizes depend on the player's choice of how many lottery-selected indicia are to be matched to the player-selected indicia.
In one embodiment, there is provided a method of playing a lottery game. The method includes the steps of receiving a first plurality of game indicia selected from a plurality of sets, receiving an indication of supplemental selection, receiving a second plurality of game indicia selected from the plurality of sets, receiving a supplemental plurality of game indicia selected from the plurality of sets, determining a first number of matches between the first plurality of game indicia and the second plurality of game indicia and determining a total number of matches according to the first number of matches and the indication of supplemental selection.
In another embodiment, there is provided a system for playing a lottery game. The system includes a communication network, at least one gaming machine in communication with the communication network, and a server in communication with the at least one gaming machine through the communication network. The server hosts the lottery game and is capable of receiving a first plurality of game indicia selected from a plurality of sets, receiving an indication of supplemental selection, receiving a second plurality of game indicia selected from the plurality of sets, receiving a supplemental plurality of game indicia selected from the plurality of sets, determining a first number of matches between the first plurality of game indicia and the second plurality of game indicia, and determining a total number of matches according to the first number of matches and the indication of supplemental selection.
In one embodiment, the invention is a lotto-style game. That is, the game comprises a player selecting indicia from a plurality of sets of indicia and submitting his selections along with a wager to a lottery system, either through a retailer operating a lottery terminal or through a self-serve kiosk. Alternatively, the player may request that the lottery system select the indicia for him as in a quick-pick option. Henceforth, it will be assumed the player has selected his own indicia. After sales for the game are closed, a drawing is held in which the lottery selects indicia from the same sets. Players may win prizes based on the number of matches between the indicia they selected and the indicia selected in the draw.
The plurality of indicia selected by the lottery from each of the sets is strictly greater than the plurality selected by the player from the corresponding set. The lottery selects its indicia from each set in a specific order. In order to match player-selected indicia with indicia selected by the lottery in excess of the plurality of player-selected indicia, the player must pay an additional amount according to a fixed schedule. Thus the player's entry must include an indication of how many of the lottery-selected indicia are to be matched with the player-selected indicia, along with a wager of the required amount.
A sample embodiment may be described as follows. At the time of purchase, the player selects one number for each of the four sets {1, 2, . . . , 15}, {16, 17, . . . , 30}, {31, 32, . . . , 45}, and {46, 47, . . . , 60}. These sets are associated with the colors yellow, red, blue, and green, respectively. At the time of the drawing the lottery will select two distinct numbers from each of these sets, in order and without replacement. Henceforth, we will refer to the first number selected from each set as a “primary” number, and we will refer to the second number selected from each set as a “supplementary” number. For the basic wager of $1 the player may match his numbers only with the primary numbers selected by the lottery. For a $3 wager, the player may also match his numbers with two supplementary numbers of his choosing as well as the primary numbers, and for $5 the player may match his numbers with any of the lottery-selected numbers, be they primary or supplementary. The player may express his intentions by filling out the playslip shown in
The playslip 100 of
Alternatively, the player may express his intentions verbally to a retailer operating a lottery terminal or by use of a self-service kiosk interface or a computer terminal connected to a centralized lottery server. The player's selection of numbers, as well as the colors of the supplementary colors in the case of a $3 wager, may also be randomly selected by the lottery terminal using technology well-known in the art.

In an alternative embodiment, the player may choose a predetermined numbers from one single large set of numbers. For example, the player may choose {2, 5, 6, 20, 35} from a set of numbers 1-50. The lottery authority will choose a set of winning numbers and a set of supplemental numbers from the same set of numbers. For example, the winning numbers may be {7, 8, 9, 20, 40} and the supplemental numbers may be {2, 11, 21, 35, 49}. The player plays the supplemental game by indicating how many supplemental numbers he wants to play. If the player plays one supplemental number, then his five numbers will be compared with the five winning numbers plus one of the supplemental numbers. In the example based on the numbers above, the player matches one winning number, 20. If the player plays one supplemental number, then the player would match two numbers, {20, 2} or {20, 35}. If the player plays two supplemental number, he would match three numbers, {20, 2, 35}.
The invention can be implemented on a standalone gaming machine or a game server. A standalone gaming device may include a display unit, a scanning unit (also known as a player input device) for scanning playslips containing player selection, and a ticket issuing unit for issuing tickets to players. The gaming device has a controller with a random number generator capable of performing quick picks for the player. The controller also takes player bets from the scanning device and issues a ticket to the player. After issuing the ticket, the controller generates a set of winning numbers and a set of supplemental numbers, and determines a number of matches for the player's ticket as described above. The gaming device may also be connected to a game server as illustrated in
At a predetermined time, the lottery authority holds a drawing of winning numbers. Besides drawing the winning numbers, the lottery authority also draws a set of supplemental numbers. Alternatively, the winning numbers and the supplemental numbers can be generated automatically by a random number generator or manually drawn by a third party. Both the winning numbers and supplemental numbers are provided to the lottery server, step 506. Alternatively, the winning numbers and supplemental numbers can be randomly generated by the lottery server or the standalone lottery station. After the winning numbers and supplemental numbers are determined, the lottery server determines number of matches between the numbers selected by the player and the winning numbers, step 508. The lottery server also checks whether the player has purchased the supplemental game, step 510. If the player has opted to play the supplemental game, the player's numbers are compared with the supplemental numbers received by the lottery server, step 512. Finally, the lottery server determines a total number of matches for the player's ticket, and the player wins a prize if the total number of matches is listed in the prize table.
