Description

  The present invention relates to a match play matching program, a matching server, and a game system.

  In competitive play, playing with players who compete with each other can play a more interesting and exciting game than playing with players with different ability to play. For this reason, in competitive play, matching is performed between players whose play ability has antagonized. For example, the play level is set to a predetermined level based on whether or not a preset condition for determining whether or not the play operation input to the game machine is a play operation performed by a player who has reached a predetermined level is satisfied. A game system has been proposed in which an advanced player flag is set by detecting a player who has reached the level and matching is performed using the flag (for example, Patent Document 1).

JP 2006-254979 A

On the other hand, in the battle play, an advanced player pretends to be a beginner, and a player who performs “beginner hunting” to defeat a real beginner is a problem.
The game system described in Patent Document 1 reaches the predetermined level of the player who has reached the predetermined level by determining the play level based on the type and the degree of the player's play operation as a countermeasure for the above problem. I knew the impersonation of a player who was not. Therefore, in the game system described in Patent Literature 1, in order to prevent impersonation, the type of play operation performed by an advanced player and the degree thereof must be assumed in advance.

  An object of the present invention is to provide a matching program, a matching server, and a game system capable of matching players who have competed in playing ability by optimizing the ability of advanced players by a simple method. It is.

  The present invention solves the above problems by the following means. In addition, in order to make an understanding easy, although the code | symbol corresponding to embodiment of this invention is attached | subjected and demonstrated, it is not limited to this. In addition, the configuration described with reference numerals may be improved as appropriate, or at least a part thereof may be replaced with another configuration.

According to the first invention, a matching program (22, 22) that determines another player who plays against one player from among a plurality of players by using an ability rating represented by a larger numerical value as the player's ability to play is higher. 222) rating storage means (23, 201) for storing the computer (1, 201) in association with player identification information for identifying the player, the ability rating, and a correction value for correcting the ability rating. 223), a player receiving means (11) for receiving the player identification information of the one player, and the corresponding ability rating and the correction from the rating storage means based on the player identification information received by the player receiving means. Acquire the value, the acquired ability rating And the matching means (12) for matching with the plurality of players using the correction value, and the winning / losing of the battle play between the other player and the one player determined by the matching means is acquired. When the one player wins the numerical value of the ability rating corresponding to the one player in accordance with the winning / losing of the battle play acquired by the play result acquiring means (13) and the play result acquiring means The rating calculation means (14) for calculating a new ability rating by decreasing the one player when the one player loses, and the one player and the other player determined by the matching means A play result predicting means (15, 215) for predicting the winning or losing of the competitive play based on the ability rating; The new ability rating calculated by the rating calculation unit is determined in a predetermined case where the win / loss of the battle play predicted by the ray result prediction unit and the win / loss of the battle play acquired by the play result acquisition unit are inconsistent. It is a matching program characterized by functioning as rating correction means (18, 218) for calculating the correction value to be corrected.
According to a second invention, in the matching program (22) of the first invention, the victory or defeat of the battle play obtained by the computer (1) by the play result obtaining means (13) is a loss of the one player. When the winning / losing of the battle play predicted by the play result predicting means (15) is a win of the one player, it functions as a correction target identifying means (16) for identifying as a correction target, and the rating correction means ( (18) is caused to function so as to increase the correction value for correcting the new ability rating calculated by the rating calculation means in response to being identified by the correction target identification means. It is a program.
According to a third aspect of the present invention, in the matching program (22) of the second aspect, the computer (1) is discriminated in correspondence with each player in response to being identified by the correction target identifying means (16). The rate correction means (18) is caused to function as a mismatch addition means (17) for adding the number of mismatches, which is the number of times the number of times of the game has been reached. In this case, the matching program is characterized in that the function for increasing the correction value for correcting the new ability rating calculated by the rating calculation means (14) is provided.
According to a fourth aspect of the present invention, in the matching program of the third aspect, the rating correction unit is configured such that the number of plays is equal to or greater than a predetermined number, and the ratio of the number of mismatches added by the mismatch addition unit to the number of plays is predetermined. And a function for increasing the correction value for correcting the new ability rating calculated by the rating calculation means when the rating value is equal to or greater than the value.
According to a fifth aspect of the present invention, in the matching program (222) of the first aspect, the play result predicting means (215) functions so as to predict the winning and losing of the battle play and the probability thereof, and the rating correcting means ( 218) is predicted by the play result predicting means and the match / mismatch between the win / loss of the match play predicted by the play result predicting means and the win / loss of the match play acquired by the play result acquiring means (13). And functioning to calculate the correction value for correcting the new ability rating calculated by the rating calculation means (14) when the probability of winning or losing the match play satisfies a predetermined condition. Matching program.

  According to a sixth aspect of the invention, there is provided a storage unit (20, 220) for storing any one of the matching programs (22, 222) from the first aspect to the fifth aspect, and the matching program stored in the storage unit.

According to the present invention, the following effects can be obtained.
(1) According to the present invention, matching is performed using a matching rating obtained by adding a correction value to an ability rating that expresses a player's play ability as a numerical value. In a predetermined case where the predicted win / loss is inconsistent, a correction value for correcting the new ability rating calculated according to the win / loss of the play result of the battle play is calculated. The predetermined case in which the winning or losing of the play result of the competitive play and the winning or losing of the competitive play predicted from the ability rating are inconsistent is, for example, the case where the advanced person impersonates the beginner, such as defeating the beginner on purpose. Say. And since the rating for matching is calculated by adding the correction value from the numerical value once reduced, the ability rating of the advanced player who deliberately lost, it is possible to calculate the matching rating that makes the ability of the advanced player's ability appropriate. By using the calculated matching rating in the next competitive play, it is possible to match players who have antagonized play ability.

(2) The present invention increases the correction value for correcting the calculated new ability rating when the play result predicted from the ability rating is “win” and the actual play result is “losing”. , Decrease the numerical value that decreases from the original ability rating. Therefore, it is difficult to make “beginner hunting” difficult by reducing the lowering of the matching rating for players who may have lost intentionally and avoiding matching with beginners in the next competitive play. it can.

(3) The present invention counts the number of times the play result predicted from the ability rating is “win” and the actual play result is “losing”, and the ratio of the number of times to the number of play is equal to or greater than a predetermined value. In this case, the correction value for correcting the calculated new ability rating is increased, and the numerical value that decreases from the original ability rating is reduced. Therefore, it is possible to make it difficult to lower the matching rating when the losing state is intentionally repeated.
(4) In the present invention, when the number of plays is a certain number of times or more, there is a possibility that the play result predicted from the ability rating is “win”, and the play result is actually “losing”. When a certain number of times is counted and the ratio of that number to the number of play times exceeds a predetermined value, the correction value for correcting the calculated new ability rating is increased, and a numerical value that decreases from the original ability rating is Make it smaller. Therefore, the correction value can be calculated more precisely by not performing correction when the number of plays is small.

(5) The present invention calculates a correction coefficient from the match / mismatch between the win / loss of the play result of the actual match play and the win / loss of the match play predicted from the ability rating, and the predicted win rate. When satisfied, the player's matching rating is reduced by a small amount, so it is determined whether or not an intentional operation has been performed to the extent that it can be determined that the player has defeated intentionally using the winning and losing ratios of the play and the winning percentage Thus, it is possible to make it difficult to lower the matching rating of the player who has performed the intentional operation.

The correction means 18 and the update means 19 are provided.
The control unit 10 is a central processing unit (CPU) that performs calculation and processing of information, and controls the matching server 1 as a whole. The control unit 10 reads and executes various programs stored in the storage unit 20 as appropriate, thereby realizing various functions according to the present invention in cooperation with the hardware of the matching server 1.

The player receiving means 11 is a control unit that receives a player ID (ID: identifier, player identification information) of a player (one player) who plays a battle from the game machine 3. Here, the player ID is a unique symbol that is assigned to each player and identifies the player.
The matching means 12 acquires an ability rating and a correction value corresponding to the player ID received by the player acceptance means 11 from the rating storage unit 23, and plays match-up based on the matching rating obtained by adding the correction value to the ability rating. It is a control part which matches the players who are going to perform. For the matching, for example, players having similar matching ratings are determined as play opponents of the battle play.

  Here, the rating will be described. The rating is a numerical value representing the play ability of the player, which is the strength of play. In the present embodiment, an ability rating and a matching rating are used as ratings. The matching rating is a rating that takes into account an illegal rating operation such as an unnatural loss by the player, and is used for matching. The matching rating is obtained by adding a correction value to an ability rating described below. The ability rating is a rating that represents the ability of the player. The higher the ability rating, the higher the playing ability and the higher the level. The ability rating can be calculated using, for example, an ilo rating technique.

The ability rating using the ilo rating method is calculated based on the following three.
(1) The result of play is only one win and the other lose. In the case of a draw, we handle 0.5 wins and 0.5 losses. The number of wins is set to “1” for winning, “0” for losing, and “0.5” for a draw.
(2) When the rate difference with the opponent player is 200, a player with a high rate shall win with a probability of 75%.
(3) The average player ability rating is 1500.

そして、実際に何回かプレイをした結果、プレイヤＡの勝ち数の合計がＳＡであった場合、Ａの新たな実力レーティングＲＡ_ＮＥＷは、以下の式で算出できる。

この実力レーティングは、その実力レーティングの数値の高い対戦相手に勝つと、その数値が大きく上昇するが、実力レーティングの数値の低い対戦相手に勝利しても、その数値があまり上昇しないように調整されている。 Assume a battle play between two players A and B. When the player's A and B ability ratings before the battle play are RA and RB, respectively, the probabilities EA and EB of each player are calculated by the following equations.

If the total number of wins of the player A is SA as a result of actually playing several times, the new ability rating RA _NEW of A can be calculated by the following equation.

This ability rating is adjusted so that if you win an opponent with a high ability rating, the figure will rise greatly, but if you win an opponent with a low ability rating, the figure will not increase much. ing.

The updating unit 19 is a control unit that updates the rating storage unit 23.
Details of these means will be described later.

The storage unit 20 includes a game program 21, a matching program 22, and a rating storage unit 23.
The game program 21 and the matching program 22 are computer programs for performing processing executed by the control unit 10. The game program 21 and the matching program 22 may be one program. Further, the game program 21 may be stored in a storage unit of another server connected to the matching server 1 via the communication network 2.
The rating storage unit 23 stores an ability rating and a correction value in association with each player ID. In addition, the storage unit 20 may include, as a temporary storage area, a local memory and a cache memory for developing tables and the like when various programs are executed.

As what implement | achieves the memory | storage part 20, you may include what implement | achieves electrically, magnetically, optically, and electromagnetically. More specifically, a semiconductor memory device including a random access memory (RAM), a read only memory (ROM), a magnetic disk, and the like are included.
Note that the computer in the present invention refers to an information processing apparatus including a storage device, a control unit, and the like, and the matching server 1 is an information processing device including the storage unit 20, the control unit 10, and the like. Included in computer concept.
Note that there is no limit on the number of hardware constituting the matching server 1. You may comprise by 1 or multiple as needed. Further, the hardware of the matching server 1 may be configured to include various servers such as an application server and a database server as necessary, or may be configured with one server or different servers. Also good.

The communication network 2 is a communication network such as the Internet for performing communication between the matching server 1 and the game machine 3. The communication network 2 may be wired communication or wireless communication.
The game machine 3 is a game device in which a player plays a battle. The game machine 3 is, for example, a device that performs a fighting game, and is installed in a play facility such as a game center. The game machines 3 may be installed in the same facility or in different facilities.

Next, processing of the matching server 1 will be described. Here, a process in a case where a matching process is performed on the player P1 who operates the game machine 3 and a one-on-one battle play is performed will be described.
FIG. 2 is a flowchart of the main process according to the first embodiment.
FIG. 3 is a diagram illustrating an example of the rating storage unit 23 according to the first embodiment.
FIG. 4 is a flowchart of the correction process according to the first embodiment.
FIG. 5 is a diagram illustrating an example of a winning / losing pattern according to the first embodiment.
First, the player P1 inputs the player ID from the game machine 3, and the game machine 3 acquires the player ID. The player ID may be input using, for example, a card medium in which the player ID is stored, or may be manually input by the player P1 operating the input device of the game machine 3.

In step S <b> 1 of FIG. 2, the control unit 10 (player accepting unit 11) of the matching server 1 accepts the player ID transmitted from the game machine 3.
In step S2, the control unit 10 (matching means 12) matches and determines the opponent player of the battle play based on the ability rating corresponding to the received player ID and the matching rating calculated from the correction value. Specifically, the control unit 10 extracts an ability rating and a correction value from a record in the rating storage unit 23 having the received player ID as the player ID 23a. Then, ability ratings and correction values corresponding to a plurality of other players requesting the battle play are respectively extracted from the rating storage unit 23. Then, the control unit 10 determines, for example, a player having a matching rating with a numerical value that approximates a matching rating obtained by adding a correction value to the ability rating of the player P1 as a play partner. Hereinafter, the opponent player who plays against the player P1 will be described as a player P2.

Here, the rating storage unit 23 will be described with reference to FIG.
The rating storage unit 23 illustrated in FIG. 3 stores the latest ability rating and correction value in association with each player ID. The player ID 23a, the ability rating 23b, the correction value 23c, and the mismatch count 23d , And the number of play times 23e.
The player ID 23a stores a player ID of a player who plays a battle and desires to be registered in the rating storage unit 23.
The ability rating 23b stores an ability rating that represents the strength of the player's play as a numerical value.

The correction value 23c stores a correction value for correcting an ability rating described later.
The number of mismatches 23d stores the number of mismatches, which is the number of times that the winning or losing of the predicted battle play is “win” and the win or loss of the actual battle play is “losing”.
The play count 23e stores the total play count of the player.
In the first play, the ability rating 23b of the player with the player ID 23a stores an average value that is an initial value, and the correction value 23c, the number of mismatches 23d, and the number of plays 23e store zero that is an initial value.

  Returning to FIG. 2, in step S <b> 3, the control unit 10 transfers control to the game machine 3, and in the game machine 3, performs a play process related to the battle play of the players P <b> 1 and P <b> 2 determined by the matching process in step S <b> 2. The play process is performed by executing a game program (not shown) of each game machine 3 of the players P1 and P2, and play data is transmitted and received between the game machines 3.

In step S <b> 4, the control unit 10 determines whether or not the battle play is ended based on the play end data received from the game machine 3. When the play ends (step S4: YES), the control unit 10 moves the process to step S5. On the other hand, if the play has not ended (step S4: NO), the control unit 10 moves the process to step S3 and continues the play process.
In step S5, the control part 10 (play result acquisition means 13) acquires a play result. As a play result, the control unit 10 acquires the wins and losses of each of the players P1 and P2. Moreover, the control part 10 counts the frequency | count of play. Specifically, 1 is added to the value of the number of play times 23e corresponding to the corresponding player in the rating storage unit 23.
In step S <b> 6, the control unit 10 (rating calculation means 14) calculates a new ability rating based on the ability ratings of the players P <b> 1 and P <b> 2 at the start of play and the play result acquired by the play result acquisition means 13. . The new ability rating can be calculated by the explanation of the ability rating described above.
In step S7, the control unit 10 performs a correction process.

Here, the correction process will be described with reference to FIG.
In step S11, the control unit 10 (play result predicting means 15) predicts the winning or losing of the play result based on the ability ratings of the players P1 and P2 who play the battle. The ability rating used in this prediction uses the ability rating stored in the ability rating 23b of the rating storage unit 23 at the start of play.

In step S12, the control unit 10 (correction target identifying means 16) compares the winning / losing of the play result predicted in step S11 with the winning / losing of the play result acquired in step S5 of FIG. Then, it is determined whether or not there is a player P1 or P2 that satisfies the correction target condition in which the predicted play result is “win” but the actual play result is “losing”. If there is one that satisfies the correction target condition (step S12: YES), the control unit 10 moves the process to step S13. On the other hand, if there is no one that satisfies the correction target condition (step S12: NO), the control unit 10 ends this process. If there is no one that satisfies the correction target condition, the control unit 10 does not perform the process of calculating the correction value.
There are six winning / losing patterns shown in FIG. For example, when the player P1 satisfies the correction target condition (pattern 2), the player P2 does not satisfy the correction target condition.

Returning to FIG. 4, in step S <b> 13, the control unit 10 (mismatch addition means 17) adds 1 to the value of the mismatch count 23 d corresponding to the corresponding player in the rating storage unit 23.
In step S <b> 14, the control unit 10 (rating correction means 18) determines that the ratio of the value stored in the mismatch count 23 d of the rating storage unit 23 to the value stored in the play count 23 e is a predetermined value (for example, “0.4 ]) It is determined whether or not the above is true. If it is equal to or greater than the predetermined value (step S14: YES), the controller 10 moves the process to step S15. On the other hand, when it is less than the predetermined value (step S14: NO), the control unit 10 ends this process.

  In step S15, the control unit 10 (rating correction means 18) performs rating correction processing. The rating correction process is to calculate a correction value for correcting the decrease in numerical value of the player of the new ability rating calculated in step S6 of FIG. Here, in the example of FIG. 3, the value of the mismatch count 23d of the rating storage unit 23 corresponding to the player P1 is “15”, the value of the play count 23e is “25”, and the ratio is “15/25”. = 0.6 ", the ability rating of the player P1 satisfies the condition for calculating the correction value,“ mismatch count / play count ≧ 0.4 ”. When the ability rating of the player P1 calculated in step S6 is “1585”, the control unit 10 sets a value that is higher than “1685” and lower than “1712” of the ability rating of the player P1 before the start of play. For example, “1700” is calculated as the matching rating. Then, the control unit 10 calculates the correction value as “1700-1685 = 15”. Then, the control part 10 complete | finishes this process.

  Returning to FIG. 2, in step S8, the control unit 10 (update means 19) updates the value of the ability rating 23b corresponding to the player ID 23a of the target player in the rating storage unit 23 to the newly calculated ability rating, The calculated correction value is added to the correction value 23c. Then, the control unit 10 subtracts “5” from the value stored in the correction value 23c. When subtracting “5” results in less than “0”, the control unit 10 stores “0” in the correction value 23c. The process of subtracting “5” is a mechanism for preventing the correction value from increasing indefinitely. In addition to the method of subtracting “5” from the value stored in the correction value 23c, another method may be used as long as the correction value does not increase infinitely. Thereafter, the control unit 10 ends the process.

  When the example of FIG. 3 is used, as described above, the new ability rating of the player P1 is “1685”. However, in the matching when the player P1 plays next time, the correction value is calculated from the new ability rating “1685”. A matching rating “1695” that is a value obtained by adding “15−5 = 10” is used.

  As described above, the matching server 1 performs matching using the matching rating obtained by adding the correction value to the ability rating that expresses the play ability of the player as a numerical value, and the play result predicted from the ability rating is “winning”. When the actual play result is “losing”, the correction value for correcting the calculated new ability rating is increased, and the value that decreases from the original ability rating is reduced. Therefore, for example, when the advanced player deliberately loses to the beginner, the lowering of the matching rating of the player who may have lost intentionally is corrected to a small level. A matching rating with appropriate player ability can be calculated. In the next competitive play, the calculated matching rating can be used to match players who have antagonized play ability.

  Then, the matching server 1 counts the number of times that the play result predicted from the ability rating is “win” but the actual play result is “losing”, and there is a possibility of losing intentionally. When the ratio to the number of times exceeds a predetermined value, the player's matching rating is reduced by a small amount. For example, when a deliberate operation is performed to such an extent that it can be determined that the player has deliberately lost, The rating can be made difficult to lower.

(Second Embodiment)
Next, a second embodiment to which the present invention is applied will be described.
The second embodiment describes a mode of correction processing that is different from the first embodiment.
Note that, in the following description and drawings, the same reference numerals or the same reference numerals are given to portions that perform the same functions as those in the first embodiment described above, and overlapping descriptions will be omitted as appropriate.

FIG. 6 is a diagram showing the overall configuration of the game system 200 and the functional configuration of the matching server 201 according to the second embodiment.
FIG. 7 is a diagram illustrating an example of the rating storage unit 223 according to the second embodiment.
The game system 200 includes a matching server 201, a communication network 2, and a plurality of game machines 3.

The control unit 210 of the matching server 201 includes a play result prediction unit 215 and a rating correction unit 218.
The play result prediction means 215 is a control unit that predicts the win / loss of the battle play and the probability that the win / loss will be established based on the ability rating of the player who plays the battle.
The rating correction unit 218 is a control unit that corrects the new ability rating calculated by the rating calculation unit 14 under conditions different from those in the first embodiment.

The storage unit 220 of the matching server 201 includes a matching program 222 and a rating storage unit 223.
The game program 21 and the matching program 222 are computer programs for performing processing executed by the control unit 210.
As shown in FIG. 7, the rating storage unit 223 includes items of a player ID 223a, an ability rating 223b, a correction value 223c, and a correction determination calculation unit 223f.
The correction determination calculation unit 223f adds and stores predetermined calculation results to be described later.

Next, processing of the matching server 201 will be described.
FIG. 8 is a flowchart of the correction process according to the second embodiment. The correction process shown in FIG. 8 is a sub-module of the main process, and the main process is the same as that of the first embodiment described in FIG.
In step S21, the control unit 210 (play result predicting means 215) predicts the winning or losing of the play result based on the ability ratings of the players P1 and P2 who play the battle. In addition, the control unit 210 (play result prediction unit 215) calculates the probability of the predicted winning or losing. Here, the ability rating used in prediction uses a value stored in the ability rating 223b of the rating storage unit 223 at the start of play. The probability can be calculated using the formula described in the above-described ability rating.

補正係数Ｒは、勝敗が確率通りであった場合に、「０」になる。また、プレイヤがわざと負ける等の行為を行い確率から外れると、補正係数Ｒは、マイナス値になる。例えば、プレイヤＰ１の勝率が「０．８」でプレイの勝者がプレイヤＰ１の場合には、補正係数Ｒは、「０．０６」（＝（１−０．８）×（０．８−０．５））である。勝敗がほぼ確率通りであるので、補正係数Ｒは、「０」に近い数値になる。他方、プレイヤＰ１の勝率が「０．７」でプレイの勝者がプレイヤＰ２の場合には、補正係数Ｒは、「−０．１４」（＝（１−０．３）×（０．３−０．５））になる。勝敗が確率に反する結果となったため、補正係数Ｒは、マイナス値になる。 In step S22, the control unit 210 calculates a correction coefficient R by the following equation.

The correction coefficient R becomes “0” when the winning / losing is in accordance with the probability. Further, when the player deliberately loses and deviates from the probability, the correction coefficient R becomes a negative value. For example, when the winning rate of the player P1 is “0.8” and the winner of the play is the player P1, the correction coefficient R is “0.06” (= (1−0.8) × (0.8−0). .5)). Since the winning / losing is almost as probable, the correction coefficient R is a numerical value close to “0”. On the other hand, when the winning percentage of the player P1 is “0.7” and the winner of the play is the player P2, the correction coefficient R is “−0.14” (= (1−0.3) × (0.3− 0.5)). Since the winning / losing result is contrary to the probability, the correction coefficient R becomes a negative value.

In step S23, the control unit 210 adds the calculated correction coefficient R to the value stored in the correction determination calculation unit 223f corresponding to the player. Then, the control unit 210 multiplies the value of the correction determination calculation unit 223f of the corresponding player after the addition by a constant “0.9”. The process of multiplying “0.9” is a mechanism for preventing the value of the correction determination calculation unit 223f from dropping infinitely. As another mechanism, for example, a method of calculating the sum of the latest n times (n is a constant such as “10”) can be considered.
In step S24, the control unit 210 determines whether or not the value stored in the correction determination calculation unit 223f is equal to or less than a predetermined value (for example, “−2”). If it is equal to or less than the predetermined value (step S24: YES), the controller 210 moves the process to step S25. On the other hand, if it is not less than the predetermined value (step S24: NO), the control unit 210 ends this process.

  In step S25, the controller 210 (rating correction means 218) performs rating correction processing. The rating correction process is to calculate a correction value for correcting the decrease in the numerical value of the player with the new ability rating calculated in step S6 of FIG. Here, in the example of FIG. 7, the value of the correction determination calculation unit 223f of the rating storage unit 223 corresponding to the player P1 is “−2.2”, and the ability rating of the player P1 is the correction condition “−”. 2 ”or less is satisfied. When the ability rating of the player P1 calculated in step S6 of FIG. 2 is “1585”, the control unit 210 is higher than “1585” and lower than “1712” of the ability rating of the player P1 before the start of play. For example, “1700” is calculated as the matching rating. Then, the control unit 10 calculates the correction value as “1700-1685 = 15”. Thereafter, the control unit 210 ends this process.

  As described above, the matching server 201 calculates the correction coefficient from the match / mismatch and the prediction win rate of the match play predicted from the actual rating and the win / loss of the match play predicted from the ability rating. When the condition is met, the player's matching rating is reduced by a small amount, so whether or not an intentional operation has been performed to the extent that it can be determined that the player has defeated intentionally using the winning and losing of the play and the winning percentage. It is possible to make it difficult to lower the matching rating of the player who has performed an intentional operation.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above. In addition, the effects described in the embodiments are merely a list of the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the embodiments. In addition, although embodiment mentioned above and the deformation | transformation form mentioned later can also be used combining suitably, detailed description is abbreviate | omitted.

(Deformation)
(1) In each embodiment, although the example of the matching using the rating of the player who plays with each of a some game machine was shown, it is not limited to this. For example, when multiple players can play with one game machine, the player may be used to determine two players from the multiple players.
(2) In each of the embodiments, description has been made using ilo rating as the ability rating, but the present invention is not limited to this. Also, the rating correction calculation formula is merely an example. As a method for finding a player whose victory or defeat is not stable with respect to the level of the opponent, various calculation formulas using ability ratings can be used.

(3) In the first embodiment, description has been given of calculating the correction value of the ability rating when the ratio of the number of mismatches to the number of plays is equal to or greater than a predetermined value. If the number is more than the number of times, the correction value may be calculated. By doing so, correction is not performed when the number of times of play is small, so that the correction value can be calculated more precisely. Moreover, the magnitude of the correction value for correcting the ability rating may be increased in accordance with the increase in the value of the ratio of the number of mismatches to the number of plays. By doing in this way, the matching server can make it difficult to lower the matching rating of the player who repeatedly loses intentionally.

(4) In each embodiment, the actual rating and the correction value are stored, and the matching rating is calculated by adding the correction value to the actual rating and then matching is performed using the matching rating. The matching rating may be stored in place of the correction value.
(5) In each embodiment, although it demonstrated as a thing which performs a play process with a matching server, you may perform with another server. In that case, it is realizable by acquiring a play result from another server which performs play processing.
(6) In each embodiment, a fighting game has been described as an example. As a competitive play, the play result is not influenced by luck, and any type of game may be used as long as the skill of the player is related to the play result.
