Abstract

In one aspect, the invention is directed to a method for conducting a wagering game that may include receiving player input corresponding to at least one first entry for a player for at least one occurrence of the wagering game, randomly selecting a supplemental entry for the player for the at least one occurrence of the wagering game such that the total number of game indicia in the first entries and the supplemental entries is equal to a predetermined maximum number of game indicia. The method may also include randomly selecting a drawing subset comprising a predetermined selected number of game indicia from the range of game indicia, comparing the game indicia of the drawing subset to the game indicia of the first entries, and determining whether any of the first entries is a winning entry based on the level of correspondence between the game indicia of the first entry and the game indicia of the drawing subset. Moreover, the method may include comparing the game indicia of the drawing subset to a combined game entry comprising the game indicia of the first entries and the supplemental entry, and determining whether the combined game entry is a second winning entry based on the level of correspondence between the game indicia of the drawing subset and the game indicia of the combined game and, if it is a second winning entry, potentially awarding a progressive jackpot.

Claims

1. A method for conducting a wagering game with an enhanced prize structure, comprising:

defining a set of game indicia;

defining a total spot entry for the game, the total spot entry corresponding to a defined number of the game indicia that is less than the total number of indicia in the set of game indicia;

receiving a player spot entry that corresponds to a number “

N”

of the game indicia, with N being in the range of from 1 to 1 less than the total spot entry, and wherein each of the game indicia in the player spot entry is unique and not duplicated;

randomly generating a supplemental spot entry for the player from the same set of game indicia, the supplemental spot entry having a number of the game indicia corresponding to the total spot entry minus N, wherein each of the game indicia in the supplemental spot entry is unique and is not duplicated in the supplemental spot entry or the player spot entry;

randomly drawing a subset of indicia from the set of game indicia, wherein the number of indicia in the randomly drawn subset is greater than the total spot entry for the game, and wherein each indicia in the drawn subset is unique and not duplicated;

comparing the game indicia of the drawn subset to the game indicia of the player spot entry to determine if a prize award is due based on the level of correspondence between the game indicia of the player spot entry and the game indicia of the drawn subset;

defining a combined spot entry that corresponds to a combination of the indicia in the player spot entry and the game indicia in the supplemental spot entry such that the number of game indicia in the combined spot entry corresponds to the total spot entry, and

comparing the game indicia in the combined spot entry to the game indicia of the drawn subset to determine if a second prize award is due based on the level of correspondence between the game indicia of the combined spot entry and the game indicia of the drawn subset.

2. The method for conducting a wagering game in accordance with claim 1, wherein the player designates the game indicia for the player spot entry.

3. The method for conducting a wagering game in accordance with claim 1, wherein the player has the option to have the game indicia for the player spot entry to be randomly generated.

4. The method for conducting a wagering game in accordance with claim 1, wherein the number of game indicia in the set of game indicia is in the range of about 80, the number of game indicia in the total spot entry is 11 and the number of game indicia in the drawn subset is 20.

5. The method for conducting a wagering game in accordance with claim 1, further comprising comparing the game indicia in the supplemental spot entry to the game indicia of the drawn subset to determine if a third prize award is due based on the level of correspondence between the game indicia of the supplemental spot entry and the game indicia of the drawn subset.

6. A gaming system for conducting a wagering game, the gaming system comprising:

a plurality of terminal units, each of the terminal units comprising;

an input device for inputting a plurality of input selections; and

a terminal unit controller operatively coupled to the input device; and

a host computer operatively coupled to the plurality of terminal units, the host computer comprising a host computer controller;

the host computer controller being programmed to define a set of game indicia, and a total spot entry for the game that corresponds to a defined number of the game indicia from the set of game indicia that is less than the total number of game indicia in the set;

the terminal unit controller being programmed to allow the input device to receive player input corresponding to receiving a player spot entry that corresponds to a number “

N”

of the game indicia, with N being in the range of from 1 to 1 less than the total spot entry, and wherein each of the game indicia in the player spot entry is unique and not duplicated;

one of the terminal unit controller or the host computer controller being programmed to randomly generate a supplemental spot entry for the player from the same set of game indicia, the supplemental spot entry having a number of the game indicia corresponding to the total spot entry minus N, wherein each of the game indicia in the supplemental spot entry is unique and is not duplicated in the supplemental spot entry or the player spot entry;

the host computer controller being programmed to randomly draw a subset of indicia from the set of game indicia, wherein the number of indicia in the randomly drawn subset is greater than the total spot entry for the game, and wherein each indicia in the drawn subset is unique and not duplicated;

one of the terminal unit controller or the host computer controller being programmed to compare the game indicia of the drawn subset to the game indicia of the player spot entry to determine if a prize award is due based on the level of correspondence between the game indicia of the player spot entry and the game indicia of the drawn subset;

one of the terminal unit controller and the host computer controller being programmed to define a combined spot entry that corresponds to a combination of the indicia in the player spot entry and the game indicia in the supplemental spot entry such that the number of game indicia in the combined spot entry corresponds to the total spot entry, and to compare the game indicia in the combined spot entry to the game indicia of the drawn subset to determine if a second prize award is due based on the level of correspondence between the game indicia of the combined spot entry and the game indicia of the drawn subset.

7. The game system in accordance with claim 6, wherein the terminal unit controller is programmed to accept a player'"'"'s designation of the game indicia for the player spot entry.

8. The game system in accordance with claim 6, wherein the terminal unit controller is programmed to randomly generate the game indicia for the player spot entry.

9. The game system in accordance with claim 6, wherein the host computer controller is programmed to define the number of game indicia in the set of game indicia in the range of whole numbers from 1 to 80, the number of game indicia in the total spot entry as 11 and the number of game indicia in the drawn subset as 20.

10. The game system in accordance with claim 6, wherein one of the terminal unit controller or the host computer controller is further programmed to compare the game indicia in the supplemental spot entry to the game indicia of the drawn subset to determine if a third prize award is due based on the level of correspondence between the game indicia of the supplemental spot entry and the game indicia of the drawn subset.
