## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. patent application Ser. No. 13/524,648, filed Jun. 15, 2012, which is incorporated herein by reference in its entirety.


BACKGROUND OF THE INVENTION
The embodiments described herein relate generally to gaming systems and, more particularly, to methods and systems for assigning bonus values associated with a random reward to one or more gaming machines.
At least some known gaming machines provide a primary game and a secondary game. For example, a secondary game may include free plays that are associated with a probability of a payout and do not require a player to deposit money or credits to the gaming machine. A secondary game may be triggered by a condition, such as a particular combination of symbols associated with a primary play outcome in the primary game. A number of different secondary games are known. For example, secondary jackpots may be used by gaming entities to encourage additional play from one or more players. An example of a secondary game is a progressive jackpot, which grows incrementally as players continue to wager at those slot machines that are linked to the progressive jackpot. Progressive jackpots are generally known as being geographically limited to a casino, are not guaranteed to payout, and are open to any player within the casino. As such, players wanting to play the progressive jackpot may be limited to only playing selected slot machines at the same casino.

Gaming system 200 is usable to provide a random reward. As used herein, the term random reward refers to a secondary game hosted by a gaming entity, which is guaranteed to pay an award, once at least one predetermined condition is satisfied. In general, the random reward is created and managed, at gaming server 202, according to various parameters, which govern payout, participation, bonus ranges, player rating, gaming machines 100, etc. Once the random reward is created, the random reward is appended to the primary games of a number of gaming machines 100, participating in the random reward.
In the exemplary embodiment, the random reward may also include, but is not limited to only including, a random bonus, or any other award that can be based on any number of factors, including random coin-in determination, a predetermined time, a random gaming machine, a random casino, a random player tracking number, and/or any combination of such factors. In one embodiment, the random reward may include bonus feature rounds, win multipliers, or free-spins for the player who triggers the random reward and/or all players associated with the random reward, including a “circle of friends”. As used herein, the term player may refer to a small group of individuals that have a relationship, such as a “circle of friends” wherein all are requested to participate in the circle. In such a relationship, generally one player oversees the circle and sends out invitations to form the circle. Such a relationship may be based on any number of factors including a preferred gaming location of the players, the age of the players, the geographic location of the players, and/or any combination of these factors and others. As such, participants in the circle of friends may be at multiple locations, may not participate through traditional casinos, and/or may use multiple devices, including those that participate remotely through the Internet, for example. In another example, participants in the circle of friends could participate through a social media account, such as through Facebook®, for example. It should be noted, that as used herein, the right to participate in the circle of friends is provided to a person and not to a specific device. In at least one embodiment, the random reward may be multiplied by the player's bet when the player triggered the random reward. Additionally, or alternatively, the random reward may be determined by the rewards account of the player triggering the random reward, and/or the rewards accounts of some or all players associated with the random reward. The random reward may be determined and/or modified, by gaming server 202, when the random reward is established, when the random reward is triggered, and/or at some point therebetween.
FIG. 5 illustrates an exemplary method 400 for providing a random reward to a plurality of players. Method 400 is described herein with reference to gaming machine 100 and gaming system 200. However, it should be appreciated, that method 400 is not limited to the gaming machine 100 and gaming system 200 and may be used with a variety of other gaming machines and gaming systems embodiments. Likewise, gaming machine 100 and/or gaming system 200 should not be understood to be limited to the exemplary system 200 of FIG. 3.
In the exemplary embodiment, gaming server 202 assigns 402 a bonus value to gaming machines 100 participating in the random reward. The bonus value can be any type of potential extra benefit to the random reward award. In the exemplary embodiment, the bonus value is a multiplier, such as, for example, 1×, 2×, 5×, 10×, 50×, 100×, 1000×, etc. The multiplier provides for a multiple of the random reward award when the random reward is triggered. For example, if a random reward is triggered by gaming activity to gaming machine 100, which has a 50× bonus value assigned thereto, the award of the random reward is multiplied by 50 and awarded to the player. It should be appreciated that various different multipliers can be used in other gaming system embodiments.
Gaming server 202 may assign 402 the same bonus value to each gaming machine 100 or one or more different bonus values to gaming machines 100. In at least one embodiment, gaming server 202 assigns 402 a smaller number of bonus values, having a higher worth, as compared to the number of bonus values having a lesser worth. In one example, if eighty gaming machines 100 are participating in a random reward, gaming server 202 may assign a 100× multiplier to one gaming machine 100, a 25× multiplier to four gaming machines 100, a 10× multiplier to fifteen gaming machines 100, and a 1× multiplier to eighty gaming machines 100. In several examples, gaming server 202 may assign 402 multiple different bonus values, including a first multiplier and a second multiplier. Gaming server 202 assigns 402 “n” first multipliers and at least “2n” second multipliers (or at least twice as many second multipliers as first multipliers). In such an example, the first multiplier is greater than the second multiplier, where “n” is an integer. It should be appreciated that gaming server 202 can assign a variety of distribution of different bonus values to gaming machines 100, to facilitate enhancing participation in the random reward, to enhance gaming activity at gaming machines 100 participating in the random reward, and/or to enhance the entertainment value provided through gaming system 200. Moreover, as described in more detail below, it should be appreciated the number, type, and/or participation of gaming machines 100 may vary, prior to, or within the duration of, the random reward, in several embodiments.
After assigning 402 the bonus values to gaming machines 100, gaming server 202 assigns 404 a different bonus value to each of a portion of gaming machines 100, after a predetermined interval. In this manner, the bonus values at gaming machine 100 change occasionally, thus providing another dimension to the random reward and bonus values associated therewith. “Different” bonus values may be assigned 404 to gaming machines 100 in a variety of different manners. As shown in FIG. 5, for example, assigning 404 different bonus values may include shuffling 406 the bonus values among the gaming machines 100. In this example, the previously assigned bonus values are shuffled 406 to different gaming machines, such that each gaming machine 100 is assigned 404 a different bonus value. In one example, gaming machine 100 is assigned 402 a 1× multiplier, and then assigned 404 a 10× multiplier through shuffling 406 the bonus values. In this example, gaming machine 100 has been assigned 404 a different bonus value, because gaming machine 100 is assigned 404 the bonus value shuffled 406 from a different gaming machine 100. Shuffling 406 generally includes the same number of bonus values, shuffled among the same number of gaming machines 100.
Additionally, or alternatively, in some embodiments, gaming server 202 may generate 408 new bonus values, rather than shuffling 406 the original bonus values, and assigns 404 the new bonus values to gaming machines 100 associated with the random reward. In such an embodiment, gaming server 202 adjusts the bonus values for a variety of different reasons, including the random reward award, and/or based on the player interacting with a particular gaming machine 100, etc. For example, bonus values may be at least partially based on the rating of a player interacting with a gaming machine 100. More specifically, in such an example, a gold rated player may be assigned 404 a 2× multiplier as a bonus value, while a platinum rated player at the same gaming machine 100, under the same conditions, may be assigned 404 a 3× multiplier as a bonus value. More specifically, the player rating may be used to generate 408 a bonus value, or enhance a pre-existing bonus value, for gaming machine 100.
In various embodiments, the bonus values may be assigned 404 based on the type of gaming machines 100, the volume of play at particular gaming machines 100, a sponsor of a random reward, and/or a variety of other reasons related to gaming machines 100, gaming system 202, and/or business reasons associated with the gaming. In one example, gaming server 202 assigns 404 higher bonus values to gaming machines receiving less traffic. In another example, gaming server 202 assigns 404 higher overall bonus values during traditionally slow times of the day/week. In still other examples, gaming server 202 assigns 404 bonus levels based on player ratings, prior bonus values, promotional periods, and/or any other reason that facilitates enhancing the award associated with the random reward.
It should be understood that a variety of different process may be used by gaming server 202 to shuffle 406, generate 408, or otherwise assign 404 different bonus values to gaming machines associated with a random reward. For example, gaming server 202 may shuffle 406 the bonus values after a predetermined time period or interval has elapsed. The predetermined interval may be any suitable interval for assigning bonus values to gaming machines 100. For example, the predetermined interval may be about 30 seconds, about 3 minutes, about 25 minutes, about an hour, or any other shorter or longer intervals, potentially depending on the random reward, the availability of gaming machines 100 associated with the random reward, and/or other conditions related or unrelated to enhancing play of gaming machines 100 associated with the random reward and/or rewarding players having particular ratings.
In some embodiments, a bonus value is preserved at gaming machine 100, even after the predetermined interval has elapsed. For example, a player may be able to retain the bonus value associated with the gaming machine, by selecting the “bonus hold” button 110. In this manner, a player is able to interact with gaming machine 100, until a high bonus value (e.g., 50× multiplier) is assigned 404 to gaming machine 100, and then retain that bonus value for further gaming activity. The option of retaining the bonus value may be restricted to players having certain ratings (e.g., silver, gold, and/or platinum) and/or certain retention intervals, after which the bonus value is released. In at least one embodiment, the “bonus hold” button 110 may be used to release the bonus value, to permit the player to pursue a better bonus value, through shuffling 406 or generation 408 of bonus values.
As gaming activity is provided to gaming machines 100, the trigger condition of the random reward is eventually satisfied. When the trigger condition is satisfied, gaming server 202 triggers 410 the random reward and awards 440 the random reward based on the bonus value assigned to gaming machine 100, thus triggering 410 the random reward. More specifically, for example, gaming server 202 multiplies the random reward by the multiplier of the bonus value. As should be apparent, the potential for triggering 410 the random reward, with dynamic bonus values, may provide enhanced entertainment to the primary game at gaming machine 100, as well as the random reward machine.
Several different trigger conditions may be employed to trigger 410 the random reward at gaming server 202. In one example, gaming server 202 includes a random number generator, at processor 306, executed through hardware, software and/or firmware. As gaming activity is accrued to gaming machines 100, gaming server 202 generates random numbers. When the randomly generated number exceeds a threshold value, the trigger condition is satisfied. As such, if the threshold value is the only trigger condition, the gaming machine 100 that facilitated generation of the random number exceeding the threshold value is determined to be the winning gaming machine.
Additionally, or alternatively, gaming server 202 may include one or more additional or alternative trigger conditions. For example, a trigger condition may be based on whether the gaming machine 100 facilitating another trigger condition is an eligible gaming machine. In one or more embodiments, gaming server 202 designates one or more gaming machines 100 as eligible for an eligibility interval. The eligibility interval may provide that select gaming machines 100 are eligible to trigger the random reward, and/or an interval of time in which gaming machines 100 are able to trigger the random reward. The eligibility interval may be assigned to one or more gaming machines 100, and/or to various time intervals, for example, to enhance participation in the random reward and/or encourage gaming activity at traditionally slower times of the day/week. Additionally, or alternatively, the eligibility interval may be set and/or adjusted to affect the probability of triggering 410 the random reward. The eligibility interval may be displayed to the player at presentation interface 118b, for example, or kept secret and/or internal to gaming server 202.
In the exemplary embodiment, gaming server 202 may alter the gaming machines 100 associated with a random reward during a random reward game play. More specifically, in one embodiment, a specific number of gaming machines 100 participate in a random reward, and are assigned 402 bonus values for the random reward. In at least one embodiment, gaming server 202 alters which gaming machines 100 are included in the random reward. In this manner, players may be encouraged to search through a gaming location to find gaming machines 100 included in the random reward. Further, gaming server 202 can alter which gaming machines 100 are included in the random reward to guide players to less popular and/or less played gaming machines 100 at a gaming location. In some embodiments, gaming machines included in the random reward remain static through the random reward, until the random reward is awarded 440.
