<<Game Outline>>

Here, an outline of a game provided by the game system 1 of the present embodiment will be described. The game system 1 provides various games conducted by using game cards (virtual cards used in a virtual space of a game).

In the game system 1 of the present embodiment, a player can possess a plurality of game cards each being associated with a game character. The player can play a battle game by using a battle deck composed of the game cards that the player possesses.

In the battle game of the present embodiment, a poker game using the battle deck is conducted. The poker game of the present embodiment is conducted by using 24 game cards selected from the game cards that the player possesses unlike the poker game conducted by using 52 cards such as the actual playing cards. Specifically, 24 game cards in combination of four suit attributes (spade, heart, club, and diamond) and six number attributes (1, 9 to 13) are used instead of 52 playing cards in combination of four suit attributes (spade, heart, club, and diamond) and 13 number attributes (1 to 13).

Upon start of the battle game, 24 game cards are selected from the game cards that the player possesses to form a preliminary deck that is a talon for the player. Five cards are then randomly selected from the preliminary deck composed of 24 game cards to form a battle deck composed of five game cards that constitute a hand. As a result of limiting the number of game cards included in a preliminary deck to 24 (24 kinds) in this manner, possible kinds of hands (also referred to as poker hands) of the poker game are also limited and the kinds of game cards that are candidates for selection in formation of a battle deck are also limited. A battle deck can thus easily make a poker hand.

The player makes his/her battle deck compete against a battle deck of an opponent, and if the player's battle deck composed of five game cards can make a preset poker hand, the player can gain a reward depending on the kind of the poker hand. In addition, if the player can exercise a skill for his/her battle deck, the player can gain a reward depending on the skill. The reward thus gained is reflected in the parameter value of the battle deck and the outcome of the battle game is determined by using the parameter value. Upon determination of the outcome of the battle game in this manner, parameter information indicating the parameter values of the battle decks at the outcome determination as well as the win/loss result are displayed to the player. Thus, player can know why the player won (or lost) and can thus accept the win/loss result of the battle game.

<<Operation of Game System 1>>

FIGS. 11 and 12 are flowcharts for explaining an example of operation of the game system 1 according to the present embodiment.

As illustrated in FIG. 11, first, in a player terminal 20, upon receiving an operation input made by the player from the terminal input unit 23, the terminal control unit 21 transmits a command (opponent selection request) for acquiring a web page for selecting an opponent to the server device 10 via the terminal communication unit 25 (S101).

Subsequently, upon receiving the opponent selection request transmitted from the player terminal 20, the server device 10 causes the screen data generation unit 118 to generate screen data (HTML data) for displaying an opponent selection screen 50 (see FIG. 13 (1)), which will be described later, on the player terminal 20 (S102). The server device 10 then transmits the screen data (HTML data) generated by the screen data generation unit 118 to the requesting player terminal 20 via the communication unit 15.

Subsequently, upon receiving the screen data (HTML data) transmitted from the server device 10, the player terminal 20 analyzes the screen data to display a game screen corresponding to the screen data on the terminal display unit 24 (S103).

FIG. 13 (1) is a diagram illustrating an example of the opponent selection screen 50 displayed on the terminal display unit 24. The opponent selection screen 50 is a game screen for selecting an opponent and includes check boxes 51 for specifying an opponent from a list and an operation button 52 for starting a battle. The player terminal 20 receives operation inputs relating to selection of an opponent and starting a battle from the player while the opponent selection screen 50 is displayed on the terminal display unit 24 (S104). It is assumed here that a “player X” is specified as the opponent for the player as a result of selection of a check box 51 and that a battle is then started as a result of selection of the operation button 52. Thereafter, the player terminal 20 transmits a battle start request in which the operation information is set to the server device 10 (S105). Upon receiving the request, the server device 10 starts a battle game with the opponent specified by the player. In the present embodiment, the battle processing unit 117 performs a battle game process for a poker game to determine the outcome.

In the battle game process for the poker game, the server device 10 first causes the first deck forming unit 114A to execute a first deck forming process (S106). The first deck forming unit 114A refers to the player information illustrated in FIG. 5 and the possessed card information illustrated in FIG. 6 to select a plurality of game cards from the cards possessed by the player and a plurality of game cards from the cards possessed by the opponent. In the present embodiment, since each possessed card has any one of the four suit attributes of spade, heart, club, and diamond, six possessed cards are selected for each suit attribute. In this process, the first deck forming unit 114A automatically selects six possessed cards on the basis of a card parameter value set for each possessed card. Specifically, the first deck forming unit 114A refers to the card information illustrated in FIG. 4 and the possessed card information illustrated in FIG. 6 and selects six possessed cards in descending order of the attack point parameter value for each suit attribute. Alternatively, the first deck forming unit 114A may select possessed cards specified by the player in response to operation input from the player instead of automatic selection mentioned above. The first deck forming unit 114A then assigns any one of six number attributes of 9, 10, 11 (jack: J), 12 (queen: Q), 13 (king: K), and 1 (ace: A) to each of the six selected possessed cards of each suit attribute. The first deck forming unit 114A then forms a preliminary deck composed of 24 game cards in combination of four suit attributes and six number attributes put into a set for each of the player and the opponent. After the preliminary decks are formed in this manner, the first deck information illustrated in FIG. 7 is stored in the data storage unit 12 of the server device 10.

Subsequently, the server device 10 causes the second deck forming unit 114B to execute a second deck forming process (S107). The second deck forming unit 114B refers to the player information illustrated in FIG. 5 and the first deck information illustrated in FIG. 7 to select a plurality of game cards from the preliminary deck of the player and a plurality of game cards from the preliminary deck of the opponent. In the present embodiment, five game cards are randomly selected from the 24 game cards included in the preliminary deck. The second deck forming unit 114B then associates the five selected game cards with unit areas, respectively, constituting a card placement area. The second deck forming unit 114B then forms a battle deck of five game cards put into a set for each of the player and the opponent. After the battle decks are formed in this manner, the second deck information illustrated in FIG. 8 is stored in the storage unit 12 of the server device 10.

Subsequently, the server device 10 performs a process of calculating deck parameter values set for the battle decks formed in this manner (S108). Hereinafter, the calculation process will be described more specifically.

FIG. 15 is a flowchart for explaining the process for calculating the deck parameters set for the battle decks.

First, the parameter determining unit 115 refers to the player information illustrated in FIG. 5, the possessed card information illustrated in FIG. 6, and the second deck information illustrated in FIG. 8 to acquire the card parameter value of each of the game cards included in the battle deck of the player (here, the attack point parameter value is acquired), and calculates the sum of all the card parameter values (S201). Similarly for the battle deck of the opponent, the parameter determining unit 115 calculates the sum of all the card parameter values. The parameter determining unit 115 then determines the sum of card parameter values thus calculated to be the deck parameter value set for the battle deck.

Alternatively, in step S201, the deck parameter value set for the battle deck may be determined by acquiring the card parameter value of each of the game cards (24 game cards) included in the preliminary deck, calculating the sum of all of the card parameter values, and determining the sum to be the deck parameter value set for the battle deck.

Subsequently, the determination unit 112 determines whether or not the parameter change condition is satisfied, that is, whether or not each of the battle decks of the player and the opponent makes a preset poker hand (S202).

If a poker hand is not made (S202: NO), this process is terminated. If, on the other hand, a poker hand is made (S202: YES), the parameter changing unit 116 refers to the card hand information illustrated in FIG. 9 to acquire the multiplier value associated with the poker hand (S203).

Subsequently, the parameter changing unit 116 changes the deck parameter value determined by the parameter determining unit 115 (S204). For example, if a poker hand “one pair” is made by the battle deck when the deck parameter value is “10000”, the multiplier value is “1.1” (see FIG. 9), and thus the deck parameter value is changed to 11000.

Alternatively, in step S204, an added value may be used instead of a multiplier value mentioned above for changing the deck parameter value determined by the parameter determining unit 115. Still alternatively, while the deck parameter value of the player is changed by using a multiplier value (or an added value), the deck parameter value of the opponent may be changed by using a divisor value (or a subtrahend value).

Referring back to FIG. 11, upon calculation of the deck parameter values set for the battle decks in the battle game process of the poker game in this manner, the server device 10 transmits the screen data (HTML data) generated by the screen data generation unit 118 to the requesting player terminal 20 via the communication unit 15 (S109).

Subsequently, the player terminal 20 analyzes the screen data (HTML data) transmitted from the server device 10 to display a game screen corresponding to the screen data on the terminal display unit 24 (S110).

FIG. 13 (2) is a diagram illustrating an example of a battle screen 60 displayed on the terminal display unit 24. The battle screen 60 is a game screen for conducting a battle between the battle deck of the player and the battle deck of the opponent, and includes a first card placement area 61, a first poker hand display area 62, a first deck parameter display area 63, a second card placement area 64, a second poker hand display area 65, a second deck parameter display area 66, a game advancement button 67, and a card exchange button 68. The first card placement area 61 is an area for placing the battle deck of the player, in which the game cards included in the battle deck are placed in five unit areas 61A to 61E, respectively. The first poker hand display area 62 is an area for displaying a poker hand made by the battle deck of the player. The first deck parameter display area 63 is an area in which parameter information indicating the deck parameter value set for the battle deck of the player is displayed. The second card placement area 64 is an area for placing the battle deck of the opponent, in which the game cards included in the battle deck are placed in five unit areas 64A to 64E, respectively. The second poker hand display area 65 is an area for displaying a poker hand made by the battle deck of the opponent. The second deck parameter display area 66 is an area in which parameter information indicating the deck parameter value set for the battle deck of the opponent is displayed. The game advancement button 67 is an operation button for advancing the battle game. The card exchange button 68 is an operation button for replacing a game card in the battle deck of the player.

In the present embodiment, since “one pair” is made by the battle deck of the player as illustrated in FIG. 13 (2), a deck parameter value resulting from the change by the parameter changing unit 116 (a value obtained by multiplying the sum of card parameters by “1.1”; see FIG. 9) is displayed as “24500” in the first deck parameter display area 63. In the meantime, it is also apparent that “one pair” is also made by the battle deck of the opponent, but since part of the game cards (the game card placed in the unit area 64E) is hidden on the display, there is a possibility that “two card” or “three of a kind” is made by the battle deck of the opponent. In addition, a deck parameter value resulting from the change by the parameter changing unit 116 (a value obtained by multiplying the sum of card parameters by the multiplier value; see FIG. 9) is displayed as “25000” in the second deck parameter display area 66. The player sees the battle screen 60 and finds out that there is a possibility of losing in this state since the deck parameter value (“24500”) of the player is smaller than the deck parameter value (“25000”) of the opponent. There is, however, a possibility that the player will come from behind and win by exercising a skill on the battle deck of the player even if the battle game is advanced in this state (exercise of a skill will be described in detail later). Alternatively, there is a possibility that the difference between the deck parameters will become larger and totally lose if “two pair” or “three of a kind” is made by the battle deck of the opponent. The player can thus select the game advancement button 67 or the card exchange button 68 taking these possibilities into account.

Here, a case in which the card exchange button 68 is selected by the player will be described. FIG. 13 (3) is a diagram illustrating a state in which a card to be replaced is selected on the battle screen 60 displayed on the terminal display unit 24. When the player selects unit areas in which game cards to be replaced are placed (herein, three game cards placed in the unit areas 61C to 61E are selected as cards to be replaced) in the first card placement area 61, the indications of “HOLD” for the game cards to be replaced disappear and the game cards to be replaced are emphasized as illustrated in FIG. 13 (3). Thereafter, when the player selects the card exchange button 68, a process for exchanging game cards is executed.

As described above, the player terminal 20 receives an operation input relating to advancement of the battle game (an input of selection of the game advancement button 67, an input of selection of the card exchange button 68, or the like) from the payer while the battle screen 60 is displayed on the terminal display unit 24 (S111). Thereafter, the player terminal 20 transmits a battle advancement request in which the operation information is set to the server device 10 (S112).

Subsequently, upon receiving the request, the server device 10 continues the battle game process for the poker game. As illustrated in FIG. 12, the server device 10 causes the determination unit 112 to execute a process of determining whether an operation input selected by the player is the input of selection of the game advancement button 67 or the input of selection of the card exchange button 68 on the basis of the received operation information (S113). If it is determined that the operation input by the player is the input of selection of the game advancement button 67 (S113: NO), the process proceeds to step S115. If, on the other hand, it is determined that the operation input by the player is the input of selection of the card exchange button 68 (S113: YES), the second deck forming unit 114B executes the second deck forming process (S114). The second deck forming unit 114B refers to the player information illustrated in FIG. 5 and the first deck information illustrated in FIG. 7 to select the number of game cards corresponding to the number of game cards to be replaced from the preliminary deck of the player. In the present embodiment, since three game cards are to be replaced (see FIG. 13 (3)), three game cards are randomly selected from 19 game cards in the preliminary deck (since five cards are already selected, not 24 but 19 game cards are candidates for selection in the preliminary deck). The second deck forming unit 114B then associates the three selected game cards with the unit areas 61C to 61E, respectively, in the card placement area 61. The second deck forming unit 114B then forms a new battle deck of five game cards put into a set. After the battle deck is formed again in this manner, the second deck information illustrated in FIG. 8 is updated and stored in the data storage unit 12 of the server device 10.

Subsequently, the server device 10 performs a process of recalculating deck parameter values set for the battle decks of the player and the opponent (S115). Hereinafter, the calculation process will be described more specifically.

First, the process of calculating the deck parameters to be set for the battle decks illustrated in FIG. 15 is executed again to calculate the deck parameter value determined by the parameter determining unit 115 or the deck parameter value resulting from the change by the parameter changing unit 116 for each of the battle decks of the player and the opponent.

Next, a process of calculating deck parameters to be set for the battle decks illustrated in FIG. 16 is executed. Here, the determination unit 112 first refers to the possessed card information illustrated in FIG. 6 and the second deck information illustrated in FIG. 8 to determine whether or not the game cards included in the battle deck of the player have a skill (S301). The determination is made similarly on the battle deck of the opponent.

If it is determined that the battle deck does not have a skill (S301: NO), this process is terminated. If, on the other hand, it is determined that the battle deck has a skill (S301: YES), the process proceeds to step S302.

Subsequently, the determination unit 112 determines whether or not the parameter change condition is satisfied, that is, whether or not the skill is to be exercised on each of the battle decks of the player and the opponent on the basis of a predetermined probability (S302).

If it is determined not to exercise the skill (S302: NO), this process is terminated. If, on the other hand, it is determined to exercise the skill (S302: YES), the parameter changing unit 116 refers to the skill information illustrated in FIG. 10 to acquire the added value associated with the skill to be exercised (S303).

Subsequently, the parameter changing unit 116 changes the deck parameter value determined by the parameter determining unit 115 (the value calculated by executing the deck parameter calculation process illustrated in FIG. 15) or the deck parameter value resulting from the change by the parameter changing unit 116 (the value calculated by executing the deck parameter calculation process illustrated in FIG. 15) by using the acquired added value (S304). For example, if a skill “A” is exercised on the battle deck when the deck parameter value (the value calculated by executing the deck parameter calculation process illustrated in FIG. 15) is “11000”, the added value is “500” (see FIG. 10) and thus the deck parameter value changes to “11500”.

Alternatively, in step S304, a multiplier value may be used instead of an added value mentioned above for changing the deck parameter value determined by the parameter determining unit 115. Still alternatively, while the deck parameter value of the player is changed by using an added value (or a multiplier value), the deck parameter value of the opponent may be changed by using a subtrahend value (or a divisor value).

Alternatively, in step S115 described above, the calculation process using a multiplier value illustrated in FIG. 15 may be executed after the calculation process using an added value illustrated in FIG. 16 is executed. For example, the card parameter values of the game cards are changed by using the added value associated with the exercised skill, and the sum of the card parameter values resulting from the change is set as the deck parameter value. Thereafter, the deck parameter value is changed by using the multiplier value associated with the poker hand that is made.

Referring back to FIG. 12, after the deck parameter values set for the battle decks of the player and the opponent are calculated again in this manner, the server device 10 causes the battle processing unit 117 to execute a win/loss determination process of determining the outcome of the battle game (S116). Specifically, the battle processing unit 117 determines the outcome of the battle game by using the deck parameter value determined by the parameter determining unit 115 (the value calculated by executing the deck parameter calculation process illustrated in FIG. 16) or the deck parameter value resulting from the change by the parameter changing unit 116 (the value calculated by executing the deck parameter calculation process illustrated in FIG. 16). More specifically, the battle processing unit 117 compares the deck parameter value set for the battle deck of the player and the deck parameter value set for the battle deck of the opponent, and determines one having the larger deck parameter value to be the winner and the other having the smaller deck parameter value to be the loser.

Note that the battle processing unit 117 changes the card parameter values (such as attack point) of the game cards included in the battle deck according to the win/loss result. As a result, the combination of game cards included in the preliminary decks for a next battle can be changed each time a battle is performed. Specifically, the kinds of game cards to be candidates for selection can be changed in formation of battle decks.

Subsequently, after the outcome is determined by the battle game process for the poker game in this manner, the server device 10 transmits screen data (HTML data) generated by the screen data generation unit 118 to the requesting player terminal 20 via the communication unit 15 (S117).

Subsequently, the player terminal 20 analyzes the screen data (HTML data) transmitted from the server device 10 to display a game screen corresponding to the screen data on the terminal display unit 24 (S118).

FIG. 14 (4) is a diagram illustrating a state after card exchange of the battle screen 60 displayed on the terminal display unit 24. In the battle screen 60, since three game cards placed in the unit areas 61C to 61E are selected to be replaced on the battle screen 60 illustrated in FIG. 13 (3), the game cards resulting from the exchange are newly placed on the unit areas 61C to 61E as illustrated in FIG. 14 (4). Furthermore, in the battle screen 60, the game card placed in the unit area 64E but hidden on the display on the battle screen 60 illustrated in FIG. 13 (3) is revealed.

In the present embodiment, since “straight” is newly made by the battle deck of the player as illustrated in FIG. 14 (4), a deck parameter value resulting from the change by the parameter changing unit 116 (a value obtained by multiplying the deck parameter before the change by “1.4”; see FIG. 9) is displayed as “45000” in the first deck parameter display area 63. In the meantime, since “two pair” is made by the battle deck of the opponent, a deck parameter value resulting from the change by the parameter changing unit 116 (a value obtained by multiplying the deck parameter before the change by “1.2”; see FIG. 9) is displayed as “30000” in the second deck parameter display area 66. When the game advancement button 67 is then selected by the player, the screen changes to the battle screen 60 illustrated in FIG. 14 (5).

FIG. 14 (5) is a diagram illustrating a state in which a skill is exercised on the battle screen 60 displayed on the terminal display unit 24. The battle screen 60 includes skill exercise display areas 69 and 70 indicating a skill being exercised on the battle decks. In the present embodiment, “20000” is added to the deck parameter as a result of exercise of the skill on the battle deck of the player, and the deck parameter value resulting from the change by the parameter changing unit 116 is displayed as “65000” in the first deck parameter display area 63. In the meantime, “2500” is added to the deck parameter as a result of exercise of the skill on the battle deck of the opponent, and the deck parameter value resulting from the change by the parameter changing unit 116 is displayed as “32500” in the second deck parameter display area 66. The player then sees the battle screen 60 and finds out that the player can win the battle game since the deck parameter value (“65000”) of the player is larger than the deck parameter value (“32500”) of the opponent. Thereafter, the screen changes to a win/loss determination screen 80 illustrated in FIG. 14 (6) and the win/loss result is presented to the player.

As described above, according to the game system 1 according to the present embodiment, a battle of the poker game is conducted between the battle deck of the player and the battle deck of the opponent, and the calculated deck parameter values of the battle decks are compared to determine the outcome of the battle game. Upon determination of the outcome of the battle game, parameter information (for example, information displayed in the deck parameter display areas on the battle screen 60) indicating the deck parameter values at the outcome determination as well as the win/loss result are displayed to the player. Thus, player can know why the player won (or lost) and can thus accept the win/loss result of the battle game.

Other Embodiments

The above-described embodiment has been given for easy understanding of the present invention, and is not to construe the present invention in a limited manner. The present invention can be modified and improved without departing from the gist of the invention and includes its equivalents. In particular, embodiments described below are also included in the present invention.

<Formation of Battle Deck>

In the above-described embodiment, an example in which the second deck forming unit 114B randomly selects game cards at a given probability from a preliminary deck for forming a battle deck is described, the present invention is not limited thereto. For example, the probability for selection may be changed depending on the kind of the number attribute set for a game card. Specifically, the probability may be set so that game cards having any of three number attributes of 12 (queen: Q), 13 (king: K), and 1 (ace: A) are less likely to be selected than the other three number attributes among the six number attributes of 9, 10, 11 (jack: J), 12 (queen: Q), 13 (king: K), and 1 (ace: A).

Furthermore, in the above-described embodiment, an example in which the deck forming unit 114 first forms battle decks, the parameter determining unit 115 then determines the deck parameter values (and the parameter changing unit 116 changes the determined deck parameter values if the determination unit 112 determines that the parameter change condition is satisfied), and the battle processing unit 117 compares the deck parameter values to determine the outcome of the battle game is described, but the present invention is not limited thereto. For example, the battle processing unit 117 may first determine the outcome, and thereafter, the parameter determining unit 115 may determine the deck parameter value of the battle decks according to the outcome determined by the battle processing unit 117, and the deck forming unit 114 may form the battle decks to meet the determined deck parameter values. Specifically, the deck forming unit 114 may select game cards so that the determined deck parameter value and the sum of card parameters agrees with each other. Alternatively, the deck forming unit 114 may select game cards so that the determined deck parameter value and the value resulting from changing the sum of card parameters agree with each other (so that the parameter change condition is satisfied by the battle deck (for example, a predetermined hand is made)).
