## Background
BACKGROUND
1. Field of the Invention
The present embodiments relate to methods for executing games in a distributed environment, and more particularly, methods, systems, and computer programs for providing viral rewards in a computer game.
2. Description of the Related Art
The popularity of casino games has extended to casino games played online. Online games such as poker, slots, blackjack, etc., are played by a large number of users on a computer. However, the enjoyment of these online games may be reduced due to the solitary nature of some of these games, such as slots, where a player bets against a machine, and more particularly, against the odds of winning offered by the machine. In a slots game, the player enters a bet and spins the wheel hoping to get a winning combination that would provide a reward. However, there is no typical social interaction with other players in the game.
Social interaction in online games is appealing to many users that wish to share some of their gaming experience with other friends, or other potential friends that may be made online. But existing slots online games do not currently provide many opportunities for social interaction with other players, nor they provide gaming interactions with other players, as the game of a slots player does not relate to the game of another slots players.
It is in this context that embodiments arise.
SUMMARY
Methods, systems, and computer programs are presented for executing a computer game. It should be appreciated that the present embodiments can be implemented in numerous ways, such as a method, an apparatus, a system, a device, or a computer program on a computer readable medium. Several embodiments are described below.
In one embodiment, a method includes an operation for setting an initial value to the jackpot of a first player. The jackpot of the first player is increased based on each bet by the first player in the computer game. Additionally, the jackpot of the first player is increased based on each bet made by friends of the first player in the computer game. The friends of the first player have a social connection with the first player, and the jackpot of the first player is independent from bets in the computer game by players that are not friends of the first player. The method further includes an operation for resetting the jackpot of the first player to the initial value when the first player or any friend of the first player wins the jackpot.
In another embodiment, a system for executing a computer game includes a memory and a jackpot manager. The memory is operable to store a jackpot state for each player of the computer game. The jackpot manager includes a processor and is operable to receive jackpot updates from players. For each jackpot update from a first player, the jackpot manager updates the jackpot states of the first player and of friends of the first player in the computer game. When the first player wins the jackpot, the jackpot manager resets the jackpot states of the first player and of the friends of the first player, while leaving unchanged the jackpot states of players that are not friends of the first player in the computer game.
In yet another embodiment, a computer program embedded in a non-transitory computer-readable storage medium, when executed by one or more processors, for executing a computer game, includes program instructions for setting an initial value to a jackpot of a first player, and program instructions for increasing the jackpot of the first player based on each bet by the first player in the computer game. Additionally, the computer program further includes program instructions for increasing the jackpot of the first player based on each bet made by friends of the first player in the computer game, where the friends of the first player have a social connection with the first player, and program instructions for resetting the jackpot to the initial value when the first player or any friend of the first player wins the jackpot. The jackpot of the first player is left unchanged when players that are not friends of the first player in the computer game win the jackpot.
Other aspects will become apparent from the following detailed description, taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION
The following embodiments describe methods, systems, and computer programs for executing a computer game. It will be apparent, that the present embodiments may be practiced without some or all of these specific details. In other instances, well known process operations have not been described in detail in order not to unnecessarily obscure the present embodiments.
FIG. 1 is a Graphical User Interface (GUI) for the lobby in a casino game, according to one embodiment. Some casinos have slots jackpots that grow over time, which are sometimes referred to as progressive jackpots because the more players gamble, the larger the jackpot grows. The formula to calculate the jackpot, or the odds for winning are typically a mystery. The probability of winning appears to be very small, and a large jackpot is only a small incentive to play, because most players believe that winning the jackpot is virtually impossible. Additionally, the jackpot in a casino is based on how much money is bet by all the players in the casino.
Embodiments provide a jackpot that has a viral component, which means that the size of the jackpot is related to social activity in the game. In one embodiment, the jackpot for each player is calculated independently, instead of having one big jackpot that is common to all the players in the casino. In addition, the size of the jackpot for each player is based on the amount bet by the player and based on the amount bet by friends of the player. In one embodiment, the jackpot of a particular player is not affected by bets performed by players that are not friends of the particular player.
It is noted that the embodiments described herein are described with reference to the slots online game, but the principles may be utilized in other online games, as well as in real-life games. The embodiments described herein should therefore not be interpreted to be exclusive or limiting, but rather exemplary or illustrative.
As used herein, a “friend” of a player refers to a person that has established a social link with the player in the game. For example, a first player has invited a second player to be “buddies” or “friends” in the game, and the second player has accepted, which makes them “friends” in the game. In other embodiments, the friendship in the game is established via a social network, such that friends of the player in the social network become friends of the player in the online game. It is noted that although two persons may be friends in real life, if the two persons have not established a friendship relationship online, they will not be considered friends in the online game. Of course, if two persons do not know each other in real life, and they do not have an online friendship relationship, the two persons will not be friends in the game. This means that, in one embodiment, the jackpots of the two persons that do not have an online friendship relationship will be independent from each other.
By linking the size of the jackpot with the play of friends, the viral component of the slots online game becomes very relevant, because the more a player plays and the more friends play, the bigger the jackpot will be. Also, the more friends that play the game, the bigger the jackpot, which encourages players to invite friends to play in the online social game to build bigger jackpots.
In one embodiment, the jackpot is referred to as a viral progressive jackpot. The jackpot is progressive because the more that players play, the bigger the jackpot will be, and the jackpot is viral because the more friends play, the bigger the jackpot will be.
FIG. 1 shows the interface of a slots game played on a portable device 102. The GUI represents a lobby where the player may select from one or more machines to play. Some of the machines, such as “Zombie Dash” 110 are locked and unavailable to the player because the player does not meet the requirements for playing that machine (e.g., the player has not earned enough stars to play Zombie Dash). Other machines like Wonderland 104 and Sea Whirl'd are open and unlocked to play the slots game. In one embodiment, the machines are referred to as theme machines because the machines are built around a theme, which includes one or more of background images, art, style, payout rates, symbols utilized in the wheels of the slots, etc. In one embodiment, as the player advances in the game, the player is given access to new theme machines that provide better chances of winning, and ability to win items that are not available in the lower level machines.
In one embodiment, message 106 shows how many friends are playing at the particular machine or what the size of the player's jackpot is. At the bottom of the GUI, and informational area 112 indicates, among other things, how much game currency the player has (e.g., 85,000) and how many stars the player has, where the stars indicate how much progress has been made in the game, gaining stars as the player spends more time playing the slots game.
FIG. 2A-2C illustrate interfaces for playing a game in a mobile device, according to one embodiment. Once the player selects a theme machine, the player is presented a GUI 202 to play slots, such as the one shown in FIG. 2A. On the top, the jackpot amount 204 is displayed. The total amount of currency to bet in the game is presented in field 206, and a progress bar 208 shows the progress made by the player in the current machine. The progress bar 208 also includes a number of stars earned in the theme machine.
The wheels 210 spin when the player presses the spin button 216. The player is able to enter the amount of lines 212 being bet on every time the wheels spin. Each of the lines includes a different combination of symbols from the wheels.
For example, one line may include the five symbols across the center line, while other lines may form different combinations of symbols, such as the top symbol on the first three wheels, followed by the center symbol in the fourth wheel, and followed by the bottom symbol in the fifth wheel.
In one embodiment, the player must get a specific combination of the wheels to win the jackpot. For example, the player must get five “jackpot” symbols across the center line. This means that the jackpot is a random event-based on the probability of obtaining the “jackpot” symbol in each of the wheels. Therefore, in one embodiment, the jackpot is based on luck and not based on other factors, such as when the jackpot reaches a certain value.
In another embodiment, the jackpot size may be also based on other factors besides the probability of the wheels, and the probability to win the jackpot may change when the jackpot reaches a certain size, or a certain age (e.g., elapsed since the jackpot was initialized), etc.
In yet another embodiment, the odds of winning the jackpot are adjusted in the computer program by aiming to obtain a winner on average for a player that plays once a week and has three sessions per day, but other odds adjusting parameters may also be utilized.
In bet field 214 the player enters the amount being bet for each line, and the total bet field 316 indicates the total amount bet in the current spin. The total bet amount is equal to the number of lines 212 times the bet per line 125. A maximum lines button 218 provides a shortcut to the player for betting the maximum number of lines.
In one embodiment, as the player spins the wheels, the jackpot continuously grows based on the amount bet by the player. In one embodiment, the jackpot growth, also referred to as the jackpot contribution by the player, is a fixed percentage of the amount bet, although the percentage amount may vary from machine to machine. For example, as the player progresses in the game the player may gain access to machines that provide biggest rewards, including a faster jackpot growth. In one embodiment, the jackpot contribution is 10 percent of the bet, and in other embodiment the jackpot contribution is in the range of 2 to 15 percent, although other values are also possible.
In another embodiment, different formulas for jackpot growth may be utilized. For example, the jackpot growth may be at a fixed percentage until the jackpot reaches a predetermined amount, and then changed to a different percentage growth afterwards, providing different accelerations for the jackpot growth at different times. In another embodiment, the jackpot grows based on a geometric function, for example growing at an exponential growth, which means that the jackpot grows faster as the jackpot gets bigger, or inverse exponential growth where the jackpot grows slower as the jackpot gets bigger.
After playing the game for a while, the player has made a certain contribution to the jackpot (e.g., 100 dollars), and the same contribution is added to the jackpots of friends of the player (which means that the jackpot of the friends have also gone up 100 dollars). Accordingly, the more friends a player has playing the game, the faster the jackpot will grow for the player. This way, jackpot growth is based on the viral contribution from friends of the player. The reciprocal is also true, when a player contributes to her own jackpot, the jackpot of the player's friends grow at the same time.
In one embodiment, the contribution Cp made by player p to the jackpot is calculated according to the following formula:

Cp=Bp*rate  (1)

Where Bp is the amount of money bet by player p since the jackpot was initialized (e.g., the time when player p or a friend of player p won the jackpot), and rate is a percentage value for determining contribution Cp. Of course, if a new player p2 establishes a new friendship relationship in the game, the jackpot Jp2 for p2 will include the contributions from the friends of p2 made after the friendship relationship was established, not including the contributions from the friends of p2 made before becoming friends in the game.
In one embodiment, the jackpot Jp of player p is calculated according to the following formula:

Jp=Cp+Σi=friend of pCi  (2)

The jackpot Jp of player p is calculated by adding the contribution Cp made by player p and the contributions Ci made by all the friends i of player p.
FIG. 2B illustrates push notifications (e.g., messages) received by the player of the online game. If the player allows, in the configuration of the game or of the mobile device, the receipt of game messages, the game will send messages according to the configuration, such as when friends of the player are playing online, when the jackpot has reached a certain value, when a bonus has been gained, when a friend has won a jackpot or when a friend has won a big jackpot, news from the game, the release of a new theme machine, a special discount sale on game currency, etc.
FIG. 2C illustrates the message shown to the player when a friend wins the jackpot (e.g., “John won the jackpot at WONDERLAND”). In one embodiment, friends of the player that wins the jackpot also get a reward. In one embodiment, each friend gets a fixed reward amount (e.g., 50 dollars, although other amounts are also possible). In another embodiment, the friends get a small percentage of the jackpot, such as one percent, although other percentage values are also possible.
FIG. 3 illustrates how the jackpot is calculated based on social relationships, according to one embodiment. As described above, the jackpot is calculated based on contributions made by a player and the player's friends. In the exemplary embodiment of FIG. 3, in order to calculate the jackpot Ja for player A, the contributions of player A and A's friend are added. A's friends are inside area 302, which includes players B, C, D, E, and F. Two amounts are associated with each player in FIG. 3, the player's contribution to the jackpot 304 and the size of the player's jackpot 306. Therefore, the jackpot Ja of player A is calculated using equation (2) as follows:

Ja=Ca+Cb+Cd+Ce+Cf+Cg 

Ja=150+100+50+540+300+400=1540

The jackpot for each player is calculated independently of the jackpot calculations for other players. Therefore, the jackpot for each player is independent from each other and not necessarily equal. In fact, most times the jackpot of the players will be different, unless two players have the same friends in the game, which will mean that both players will have the same jackpot. Of course, there may be other jackpot contribution factors such as level of expertise, a jackpot increase bonus won by a player, etc., which may make the jackpots different.
In one embodiment, if two players playing the game only have each other as friends, their jackpots will be identical, independent of how much each of the players bet on the game. For example, players K and L only have each other as friends. While player K has contributed 95,000 to the jackpot and player L has only contributed 600 to the jackpot, both players have the same jackpot with a value of 95,600. It does not matter that player K has played much more than player L, their jackpots are the same. Of course, since player K seems to play much more than player L, player K will likely have a bigger probability of winning the jackpot, just because player K plays more often.
When a player wins, the jackpot of the player gets reset to an initial value (e.g., 100, although other values are also possible), which may be different in the different theme machines. In addition, when a player wins, the jackpots of the friends players are also reset to the initial value. Because of this, a player wants to win the jackpot before any of the player's friends do, because if any friend wins then the player's jackpot gets reset. For example, a player that may have played a lot (e.g., the player has “heated the machine”) does not want all her efforts to go to waste by having a friend “steal” the jackpot away from her. On the other hand, an opportunistic player that has not played a lot may realize that a large jackpot is available and decide to start playing more in order to increase the chances of winning the jackpot. Of course, “parasitic” players may not have long social relationships in the game as players may not like having their jackpot “stolen” away from players that do not contribute their share to the jackpot. Having many friends means that a player's jackpot will grow fast, but it also means that there are more players competing to win the jackpot.
In the scenario where a new player starts playing the game, once the player establishes friendship relationships in the game, the player will start competing for the jackpot. If the friends of the new player have been playing for a while, the friends may have built build a large jackpot, but since the new player has recently joined, the new player will have a smaller jackpot. However, if the new player wins, all the jackpots are reset, which means that the new player will win a relatively small jackpot, but the player's friends will lose the large jackpot that they had built.
FIG. 4 shows a flowchart illustrating an algorithm for determining the jackpot in the computer game, in accordance with one embodiment. In one embodiment, when a player wins the jackpot, three things happened:
1. The player gets the jackpot;
2. The friends of the player receive a consolation prize; and
3. The jackpot of the player and the jackpots of the player's friends are reset to an initial value.
The method described in FIG. 4 outlines some of the operations related to jackpot management. In operation 402, a player bets a certain amount X and spins the wheels. A check is made to determine if the player has won the jackpot in operation 404. If the player did not win the jackpot, the method flows to operation 406 where a contribution amount Y, based on the amount bet X, is added to the jackpot of the player and to the jackpots of the player's friends. From operation 406, the method flows back to operation 402.
If the player wins the jackpot, the method flows from operation 404 to operation 408, where the player is credited with the amount of the jackpot. After operation 408, the method flows to operation 410 where a reward is given to the player's friends in order to “share the fortune” of the player that won the jackpot. In one embodiment, each friend gets a fixed reward amount (e.g., 25 dollars, although other amounts are also possible). In another embodiment, the friends get a small percentage of the jackpot, such as one percent, although other percentage values are also possible.
From operation 410, the method flows to operation 412 where the jackpots of the player that won the jackpot and the jackpots of the player's friends are reset to the initial value.
FIG. 5A illustrates the interaction between client and server regarding updates to the value of jackpots, according to one embodiment. In one embodiment, the online game is hosted by server 512, which includes a jackpot manager 514, a game manager 516, and a social manager 518. A player P1 501 plays the game utilizing client device 502 executing a computer program that includes a client state object 504 with jackpot related information. In one embodiment, the client 502 utilizes a web browser, and in another embodiment other computer programs may also be utilized to play the game, such as a computer program loaded on a computing device for the exclusive purpose of playing the game.
The client state object 504 tracks the amounts bet on one slot machine. In one embodiment, there is one client state object 504 per machine for the player. In one embodiment, the client state object 504 includes one or more of a current jackpot amount, a history of one or more most recent jackpot updates, jackpot contributions from the player's friends, timestamps for the jackpot contribution updates, history of times and duration of playing sessions, time of last synchronization with server, player identification, a cache of the list of player's friends, or any other game-related data.
Every time a bet is placed, a percentage of the bet is used as the added contribution for the jackpot state. Periodically (e.g., every five minutes, although other intervals are also possible), the jackpot state kept at the client is synchronized with the server 512. The client state object 504 sends information 506 regarding bets placed and current jackpot to the jackpot manager 514 in the server 512. The jackpot manager controls the state of the jackpots in each of the machines, and performs the synchronization required with the client state object of all players.
The jackpot manager 514 analyzes the received updates with game information 506 and determines the machine associated with the update, and what was the jackpot contribution. The jackpot manager 514 queries the social manager 518 for the social graph of user 501, where the social graph includes the identities of the friends of player 501 in the game. The social manager 518 manages the friendship relationships established in the game.
The jackpot manager 514 updates the jackpot information based on the received updates and notifies the game manager 516, so players have access to the current jackpot information. In one embodiment, the game manager 516 access shared data structures with the jackpot manager regarding the state of the jackpots for the players of the game. In one embodiment, the shared data structure includes jackpot states 524 for the game players.
In another embodiment, the jackpot states 526 for the players have an associated update queue 528 that holds the different jackpot updates for the respective player. Therefore, every time an update is received by the jackpot manager, after checking the social graph of the originating player, the jackpot manager places an update 522 in each of the friends of the jackpot contributor, as well as in the queue of the jackpot contributor. In one embodiment, the jackpot manager updates the jackpot state of the jackpot contributed immediately, without having to plays the update in the jackpot queue.
In one embodiment, the queued transactions include how much has been added to the jackpot, or that the jackpot has been won by a player. In one embodiment, a background process from the jackpot manager 514 processes the queues of the different players to update the jackpot values. In one embodiment, the queues of players that are not currently playing the game are not processed until a player starts playing the game. This way, processing time is saved by postponing the processing of updates until the update is needed when a player is in the game. In another embodiment, the background process perform some processing of the queues of players that are not playing the game when there are available resources to do so (e.g., a period of low gaming activity) or when the queues become large, exceeding a predetermined value of items in the queue.
It is noted that some of the jackpot updates 530 may be for a “jackpot win” transaction. In one embodiment, the jackpot manager adds the jackpot-win transaction to the end of the queues of the friends of the winner, and the transaction will be processed like any other jackpot-contribution transaction. In another embodiment, the jackpot manager determines that a win transaction has been received and clears the queues of all the friends of the winner, and then adds the win transaction to these queues. Since the win transaction resets the value of the jackpots, the jackpot manager does not have to process all the queued up transactions leading up to the jackpot-win transaction because the final outcome is always a jackpot reset.
When a player logs in, the jackpot manager 514 runs through the queue and tallies up the jackpot amount for the player that logged in. If a jackpot-win transaction is found, the jackpot manager 514 resets the jackpot back to the starting point for the jackpot. After the jackpot manager 514 tallies up all the transactions when a new player logs in, the jackpot manager 514 updates the jackpot amount for the player, and may indicate if a friend won the jackpot.
When player 501 is playing the game, the jackpot manager 514 sends updates to the client 502 regarding jackpot contributions 510 or regarding jackpot wins 508 from friends of player 501 that are currently playing the game at the same time. In one embodiment, if the friend wins the jackpot (i.e., a jackpot-win transaction 508 is received), the client object 504 resets the value of the jackpot for player 501.
It is noted that the embodiments illustrated in FIG. 5A are exemplary. Other embodiments may utilize different update mechanisms, different modules, or combine the functionality of one or more modules into a single module. The embodiments illustrated in FIG. 5A should therefore not be interpreted to be exclusive or limiting, but rather exemplary or illustrative.
FIG. 5B illustrates the format of the data structure, or message, used to inform the server of the jackpot update. This message is sent from the client in the player's computing device to the server, but in some embodiments the same message format may be used to send updates from the server to the client, or from the client to the clients of other players. In one embodiment, the message includes a transaction ID, a player ID, a timestamp, a name of the theme machine, amount bet, contribution to the jackpot, and the current jackpot value.
The transaction ID is a unique value associated with the message being sent, and may be used to detect duplicate messages. In another embodiment (not shown) the transaction ID of the previous message sent is also included in order to allow the server to detect missing transactions (e.g., missing jackpot updates). The player ID is a unique identifier in the online game of the player where the message originated. The timestamp includes the date and time when the message was sent to the server.
The machine field identifies the machine where a bet was made, and the contribution indicates how much was added to the jackpot. The jackpot value indicates the current value of the jackpot associated with the timestamp. The timestamp on the jackpot value may be utilized, in some embodiments, to synchronize the jackpot value between the client and the server.
FIG. 5C illustrates the format of the data structure, or message, used to inform the player's computing device of a jackpot update. This message is sent from the server to the player's computing device. In one embodiment, the message includes a transaction ID, a player ID, a timestamp, a name of the theme machine, amount bet, a contribution to the jackpot, the current jackpot value, and a message.
The fields in FIG. 5C have the same meaning as the fields In FIG. 5B, except that the amount bet represents the amount bet by one or more friends of the player, and the contribution represents the contribution to the jackpot by one or more friends of the player. In addition, an informational message may be included provide additional information to the player (e.g. “3 of your friends added $60 dollars to the jackpot”). This message may be presented to the player in an informational window within the GUI, or as a pop-up message.
It is appreciated that the embodiments illustrated in FIGS. 5B-5C are exemplary. Other embodiments may utilize different fields, present the fields in a different order, combine one or more fields into one, omit one or more fields, etc. The embodiments illustrated in FIGS. 5B-5C should therefore not be interpreted to be exclusive or limiting, but rather exemplary or illustrative.
FIG. 6 shows a flowchart illustrating an algorithm for executing a computer game, in accordance with one embodiment. In operation 602, the initial value of the jackpot of the first player is set. In one embodiment, the initial value is set to a fixed amount, and the different theme machines may include different initial values. In one embodiment, as the player progresses in the game, the player gains access to better theme machines with higher initial jackpots.
From operation 602 the method flows to operation 604, where the jackpot of the first player is increased based on bets by the first player in the computer game. In one embodiment, the increment is a fixed percentage of the amount bet by the first player (e.g., see equation (1) described above with reference to FIG. 2A).
From operation 604 the method flows to operation 606, where the jackpot of the first player is increased based on the bets made by friends of the first player in the computer game. In one embodiment, operation 604 and 606 are performed utilizing equation (2) described above with reference to FIG. 2A, but other equations based on the jackpot contributions for different players may also be utilized. The first player's friends have a social connection with the first player in the game, and the jackpot of the first player is independent from bets in the computer game by players that are not friends of the first player.
From operation 606 the method flows to operation 608 where the jackpot of the first player is reset to the initial value when the first player or when any friend of the first player wins the jackpot. In one embodiment, the method is executed by a processor.
FIG. 7 shows a block diagram illustrating a social gaming network architecture, according to one embodiment. In some implementations, a plurality of players (e.g., 251a-251f) may be utilizing a social gaming network 250. Each player interacts with the social gaming network via one or more client devices (e.g., client devices 252a-252f). The clients may communicate with each other and with other entities affiliated with the gaming platform via communications network 255. Further, the players may be utilizing a social networking service provided by a social networking server (e.g., social networking servers 253) to interact with each other.
When a player provides an input into the player's client device, the client device may in response send a message via the communications network to the social networking server. The social networking server may update the player profile, save the message to a database, send messages to other players, etc. The social gaming network may include a social graph database 254, which stores player relationships, social player profiles, player messages, and player social data.
The gaming servers 261 host one or more gaming applications, and perform the computations necessary to provide the gaming features to the players and clients. One or more gaming databases 262 store data related to the gaming services, such as the gaming applications and modules, virtual gaming environment data, player gaming session data, player scores, player virtual gaming profiles, game stage levels, etc. The gaming servers may utilize the data from the gaming databases to perform the computations related to providing gaming services for the players.
Jackpot Servers 272 manage the jackpot system in the game, including the creation, tracking, expiration, abandonment, and deletion of jackpots. In addition, a jackpot database 270 holds jackpot state information, such as the jackpot states 524 of FIG. 5A.
FIG. 8 illustrates an implementation of an online game infrastructure, according to one embodiment. The online game infrastructure 476 includes one or more game servers 458, web servers (not shown), one or more social network management servers 462, and databases to store game related information. In one embodiment, game server 458 provides a user interface 460 for players 452 to play the online game. In one embodiment, game server 458 includes a Web server for players 452 to access the game via web browser 454, but the Web server may also be hosted in a server different from game server 458. Network 456 interconnects players 452 with the one or more game servers 458.
Each game server 458 has access to one or more game databases 466 for keeping game data. In addition, a single database can store game data for one or more online games. Each game server 458 may also include one or more levels of caching. Game data cache 464 is a game data cache for the game data stored in game databases 466. For increased performance, caching may be performed in several levels of caching. For instance, data more frequently used is stored in a high priority cache, while data requiring less access during a session will be cached and updated less frequently.
The number of game servers 458 changes over time, as the gaming platform is an extensible platform that changes the number of game servers according to the load on the gaming infrastructure. As a result, the number of game servers will be higher during peak playing times, and the number of game servers will be lower during off-peak hours. In one embodiment, the increase or decrease of bandwidth is executed automatically, based on current line usage or based on historical data.
One or more social network management servers 462 provide support for the social features incorporated into the online games. The social network management servers 462 access social data 478 from one or more social networks 474 via Application Programming Interfaces (API) 472 made available by the social network providers. An example of a social network is Facebook, but it is possible to have other embodiments implemented in other social networks. Each social network 474 includes social data 478, and this social data 478, or a fraction of the social data, is made available via API 472. As in the case of the game servers, the number of social network management servers 462 that are active at a point in time changes according to the load on the infrastructure. As the demand for social data increases, the number of social network management servers 462 increases. Social network management servers 462 cache user data in database 468, and social data in database 470. The social data may include the social networks where a player is present, the social relationships for the player, the frequency of interaction of the player with the social network and with other players, etc. Additionally, the user data kept in database 468 may include the player's name, demographics, e-mail, games played, frequency of access to the game infrastructure, etc.
It is noted that the embodiment illustrated in FIG. 8 is an exemplary online gaming infrastructure. Other embodiments may utilize different types of servers, databases, APIs, etc., and the functionality of several servers can be provided by a single server, or the functionality can be spread across a plurality of distributed servers. The embodiment illustrated in FIG. 8 should therefore not be interpreted to be exclusive or limiting, but rather exemplary or illustrative.
