(game description)
A "game" in the following description is a video game that progresses in response to user operations. This game includes a first event that is performed using a first virtual medium and a second event that generates a second virtual medium. The second virtual medium is a virtual medium generated using a material medium related to the first virtual medium and a third virtual medium.

Note that, in the following example, the material medium is a virtual medium related to the first virtual medium whose use in the first event is restricted. A material medium is a virtual medium generated based on the first virtual medium. Alternatively, the material medium is the first virtual medium permitted to be used in the second event. A third virtual medium is available at the first event and the second event.

Also, the second virtual medium changes to the first virtual medium or the third virtual medium that can be used in the first event by satisfying a predetermined condition.

In the following description, a simulation game is taken as an example in which the player can experience the trading and breeding of horses (virtual media) in a virtual space. In this simulation game, first, initial settings are performed. In the initial setting, selection and setting of the ranch, ranch manager, trainer, secretary, etc. are performed. After completing the initial settings, the game proceeds. The simulation game includes events such as trading events, training events, racing events, compounding events, and the like.

The horses (virtual mediums) that appear in this simulation game are roughly classified into 'stalls' and 'mares'. Stallions include "racehorses" and "stallions." A racehorse is a stallion available in a racing event. A stallion is a stallion available in a blended event. Similarly, mares include "racemares" available at racing events and "broodmares" available at blending events. Racemares are mares available in racing events and broodmares are mares available in blending events.

For example, when a racehorse retires from a racing event, it is no longer available as a racehorse at racing events and becomes an available stallion at blended events. When a racemare retires in a racing event, it is no longer available as a racehorse in racing events and becomes an available broodmare in blending events. Stallions are treated as "race stallion related stallion breeds (stallion breeds)" as shown in FIG. Alternatively, the stallion is treated as "a stallion (stallion) permitted to be used in a compounding event" as shown in FIG.

In addition, in the following explanation, racehorses and racehorses are collectively referred to as "racehorses." A horse born from a combination (breeding) of a stallion and a broodmare is described as a "offspring". The progeny includes progeny of stallions and progeny of mares.

[Trading event]
In a trading event, horses are bought and sold. For example, horse auctions are held. When this transaction is concluded, the "ownership", which is the right to own the horse, is transferred from the seller to the buyer, and the buyer pays the seller the consideration. Examples of horses to be traded include racehorses (including progeny), broodmares, and stallions.

In addition, at the trading event, the trading of the "right of use", which is the right to use the stallion (seed of the stallion) in the compounding event, is also carried out. When this transaction is concluded, the right to use is transferred from the seller to the buyer, and the consideration is paid from the buyer to the seller.

[Training event]
In the training event, training of racehorses is performed. For example, selection of a trainer to be in charge of training a racehorse, determination of a training menu, and the like are performed. By training the racehorse, it is possible to change the parameters (ability values) of the racehorse. For example, racehorse parameters can be improved.

[Race event]
In the race event, racehorses run in a race, and races are held by the racehorses. When the race by the racehorse is completed, the owner of the racehorse is awarded a prize according to the race result of the racehorse. Also, the results of the race event are stored in association with the racehorses that entered the race in the race event.

[Combination event]
A breeding event involves mating (breeding) a stallion and a broodmare. Successful mating between a stallion and a broodmare produces offspring. A progeny is raised by a ranch manager in a ranch until it reaches a predetermined reference age (specifically, 2 years old).

After reaching the reference age, the progeny will be trained as a racehorse in a training event and will be available for use in the race event. Specifically, a progeny can become a racehorse of the next generation through breeding. In other words, the progeny born from the blending of the "nth generation stallion and broodmare" corresponding to the nth generation racehorse and racemare will become the "n-1th generation racehorse" through breeding. obtain.

[Flow of time]
Also, in this simulation game, there is a predetermined flow of time. This flow of time may be the same as the flow of time in the real world, or may be the flow of time progressing in the game (the flow of time different from the flow of time in the real world). The various events described above are held during predetermined periods. For example, racing events may occur on weekends (Saturday and Sunday), and other events, except racing events, may occur on weekdays (Monday through Friday). Note that compounding events are only available in May and June. If the blending event succeeds, offspring will be born in a predetermined period (eg March to May).

[Correspondence of terms]
A race event is an example of "a first event that is held using a first virtual medium". A compounding event is an example of a "second event that generates a second virtual medium". A stallion (specifically, a racehorse) is an example of a "first virtual medium." A progeny is "an example of a second virtual medium".

A mare is an example of a "third virtual medium." Specifically, a racemare is an example of "a third virtual medium that can be used in the first event", and a broodmare is an example of "a third virtual medium that can be used in the second event". For example, a broodmare can give birth to one foal once a year.

A stallion is an example of a "material medium associated with the first virtual medium". Specifically, stallion breeds related to racehorses (stallion breeds) are an example of "material medium generated based on the first virtual medium", and stallions permitted to be used in compounding events ( Stallion) is an example of "a material medium that is a first virtual medium permitted to be used in the second event".

(Embodiment 1)
FIG. 1 illustrates the configuration of a game system 1 of Embodiment 1. As shown in FIG. A game system 1 includes a server device 10 and a plurality of game devices 20 . In the game system 1 , a server device 10 and a plurality of game devices 20 are communicably connected via a communication network 5 . Examples of the communication network 5 include the Internet and LAN.

[Outline of game system]
The server device 10 manages users and games. A display 31 , a speaker 32 and a game controller 33 are connected to each of the plurality of game devices 20 . The game device 20 executes a game. For example, the game device 20 is a commercially available device such as a personal computer, PlayStation (registered trademark), XBox (registered trademark), or Nintendo Switch (registered trademark). In the case of a cloud-type game, the game device 20 is, for example, a device such as a game server. In this case, the game screen is displayed on the display 31 connected via the communication network 5 .

Server device 10 and game device 20 communicate with each other via communication network 5 . For example, server device 10 transmits a game program and game data for executing a game as needed (for example, in response to a request from game device 20). The game device 20 receives (downloads) the game program and game data from the server device 10 via the communication network 5 and installs them.

For example, in a game in which a plurality of users (players) participate at the same time, the game progresses as the server device 10 and the game device 20 operate cooperatively. In this case, the progress of the game is managed by the server device 10 .

Specifically, the server device 10 transmits game data for executing the game to the game device 20 . Based on the game data transmitted from server device 10 , game device 20 causes display 31 and speaker 32 to output images and sounds related to the game. The user operates the game controller 33 according to the images and sounds output from the display 31 and speaker 32 .

The game device 20 transmits operation information indicating the operation input to the game controller 33 to the server device 10 . Based on the operation information transmitted from the game device 20 , the server device 10 generates game data reflecting the operation information, and transmits the game data to the game device 20 .

The game progresses by repeating the above processes.

Also, in this example, each game device 20 is one of a plurality of nodes that constitute a distributed ledger (so-called block chain). Each of the multiple nodes (communication terminals) shares distributed ledger data. "Distributed ledger data" and "information stored in distributed ledger" will be explained in detail later.

[Hardware configuration of server device]
As shown in FIG. 1, the server device 10 includes a network interface 11, a storage unit 12, and a control unit 13. Network interface 11 and storage unit 12 are electrically connected to control unit 13 via bus 14 .

The control unit 13 controls operations of the server device 10 . The control unit 13 transmits and receives various information and data, and processes various information and data. The control unit 13 has a CPU (microcomputer) and a semiconductor memory. The semiconductor memory stores programs and the like for operating the CPU.

[Hardware Configuration of Game Device]
As shown in FIG. 2 , the game device 20 includes a network interface 21 , a graphics processing section 22 , an audio processing section 23 , an operation section 24 , a storage section 25 and a control section 26 . The network interface 21 , the graphics processing unit 22 , the audio processing unit 23 , the operation unit 24 and the storage unit 25 are electrically connected to the control unit 26 via the bus 27 .

The network interface 21 is communicably connected to the server device 10 via the communication network 5 .

A display 31 is connected to the graphics processing unit 22 . The graphics processing unit 22 draws a game image including various objections related to the virtual space in a moving image format according to the game image information output from the control unit 26 . A game image drawn in a moving image format is displayed on the display 31 as a game screen.

A speaker 32 is connected to the audio processing unit 23 . The audio processing unit 23 reproduces and synthesizes game sounds according to instructions from the control unit 26 . A game sound reproduced and synthesized by the audio processing unit 23 is output from the speaker 32 .

A game controller 33 is connected to the operation unit 24 . The operation unit 24 transmits and receives data regarding operation inputs to and from the game controller 33 . The operation unit 24 then transmits operation information indicating the operation input to the game controller 33 to the control unit 26 .

For example, the game controller 33 is provided with various operators such as buttons. The user inputs operation signals to the game apparatus 20 by operating various operators of the game controller 33 . That is, when the game controller 33 is operated by the user, the game controller 33 transmits an operation signal corresponding to the operation by the user to the operation unit 24 . The operation unit 24 generates operation information based on the operation signal and transmits the operation information to the control unit 26 .

The storage unit 25 stores various information and data. The storage unit 25 is composed of an HDD, SSD, RAM, ROM, and the like. For example, the storage unit 25 stores a game program and game data for executing a game. Information stored in the storage unit 25 will be described later in detail.

The control unit 26 controls operations of the game device 20 . The control unit 26 transmits and receives various information and data, and processes various information and data. The control unit 26 has a CPU (microcomputer) and a semiconductor memory. The semiconductor memory stores programs and the like for operating the CPU.

[Functional Configuration of Control Unit in Game Device]
The control unit 26 of the game device 20 has a progression unit 201 , a management unit 202 and a generation unit 203 . Specifically, the control unit 26 functions as a progression unit 201, a management unit 202, and a generation unit 203 as a result of the CPU executing various programs.

〈Proceedings〉
The progression unit 201 progresses the game. The game includes racing events conducted using racehorses and compounding events that generate progeny. As shown in FIG. 3, a progeny is a virtual medium generated using a stallion (sire breed) related to a racehorse and a broodmare. A stallion is virtual media that is generated based on a racehorse and that is consumed through use in compounding events.

In this example, the game includes trading events, training events, etc., as well as racing and compounding events. A stallion is a virtual medium associated with a stallion (stallion) for limited use in racing events.

<Management Department>
The management unit 202 manages rights used in the game (for example, ownership of horses). The management unit 202 also performs ledger registration processing. The ledger registration process is a process for processing various transactions in the game and registering (storing and approving, hereinafter the same) the results in the distributed ledger. The ledger registration process will be described later in detail.

In this example, the management unit 202 associates "utilization rights" related to stallion breeds (stallion breeds) with "users" who use the utilization rights, based on distributed ledger technology. Specifically, when a transaction regarding the usage right is performed, the management unit 202 performs ledger registration processing to register the transaction result in the distributed ledger.

The right to use the stallion breed is the right to use the stallion breed in the compounding event. The usage right is a right with an upper limit on the number of available parameters (usable number). The right of use is a right that can be used individually by a plurality of users who have requested and been approved for use.

In this example, the right of use is a right with a set number of times of use. When the usage right is used once, the number of times the usage right can be used is reduced by one. When the number of times the usage right can be used reaches zero, the usage right can no longer be used.

In Embodiment 1, the transfer of usage rights is performed at the same time as the transfer of the stallion breed. For example, when user A is granted 10 times of stallion A, user A is granted a usage right (a usage right of stallion A) whose number of times of usage is set to 10 times. In addition, when user A transfers stallion A to user B five times, the number of times the usage rights granted to user A (the rights to use stallion A) can be used decreases from 10 to 5, User B is granted a usage right (a usage right for stallion A) with the number of times it can be used set to five.

In addition, the "usable parameter" of the usage right corresponds to the total number of usage times (maximum number of usage rights issued) in the compounding event of the stallion breed (material medium) that can be used by the usage right. Specifically, the above-mentioned "usable parameter" corresponds to the number of possible matings (number of possible matings) in the life of the stallion.

In the first embodiment, the "available parameter" of usage rights related to stallion breeds is the same as the total number of stallions generated based on racehorses in the stallion conversion process, which will be described later. In addition, the total number of available usage rights for all horse breeds is the same as the remaining number for that stallion breed.

In addition, the management unit 202 associates the “ownership” of the racehorse with the “users” who use the ownership, based on the distributed ledger technology. Specifically, when an ownership transaction is performed, the management unit 202 performs ledger registration processing to register the transaction result in the distributed ledger. In addition, the property right related to the racehorse is the right to use the racehorse in the first event.

In addition, the management unit 202 associates "ownership" of progeny with "users" who use the ownership, based on the distributed ledger technology. Specifically, when an ownership transaction is performed, the management unit 202 performs ledger registration processing to register the transaction result in the distributed ledger. In addition, the ownership of the progeny is the right to use the progeny in the first event.

<Generation part>
The generation unit 203 generates a virtual medium (for example, a stallion) used in the game. In addition, the generating unit 203 grants (sets) a right (for example, ownership of a horse) to be used in the game.

As shown in FIG. 3, the generation unit 203 generates a plurality of stallion breeds based on racehorses in the stallion conversion process. The mare conversion process is a process for converting a racehorse into a stallion and generating a stallion breed. The stallion conversion process will be described later in detail.

Moreover, as shown in FIG. 3, the generation unit 203 converts a racemare into a broodmare in the mare conversion process. A mare conversion process is a process for converting a racemare into a broodmare. The filly conversion process will be described later in detail.

In addition, as shown in FIG. 3, the generation unit 203 generates offspring using a stallion breed and a broodmare in response to an instruction from a user who uses the usage right in a blending process performed at a blending event. A blending process is a process for producing offspring using a stallion breed and a broodmare. The compounding process will be described later in detail.

It should be noted that the generation of the offspring described above is affected by the "game result in a race event for racehorses related to the stallion breed". In this example, the generation of the above progeny is based not only on the "game results in race events for racehorses associated with the stallion breed", but also "game results in broodmare race events (race events when they were racemares)". game result)” is also affected.

Also, in the blending event, it is determined whether or not the progeny will be generated according to a predetermined probability of success. In other words, the blending (seeding) in the blending event succeeds according to a predetermined probability of success. If the combination succeeds, the offspring will be born, and if the combination fails, no offspring will be born.

[Distributed ledger data]
Next, with reference to FIG. 4, distributed ledger data (blockchain data) shared by each of a plurality of nodes forming a distributed ledger will be described.

As shown in FIG. 4, distributed ledger data is composed of a plurality of blocks that are strung together. Blocks are data including hash values, nonce values, transactions (tokens), and so on. A transaction includes historical data that indicates the outcome of the transaction. The history data includes information for identifying the transaction target, information for identifying parties to the transaction, and the like.

In the example of FIG. 4, the transaction of the k-th block is that the right to use "stallion A" is transferred from "user A" to "user B", and the compensation for the transfer of the right to use is from "user B". It shows that "User A" has been paid.

[Ledger registration process]
Next, the ledger registration process by the management unit 202 will be described. In the ledger registration process, the management unit 202 generates history data indicating transaction results, and generates a transaction including the history data. Then, the management unit 202 transmits the generated transaction to the distributed ledger (more specifically, multiple nodes forming the distributed ledger).

In the distributed ledger, processing is performed to add new blocks containing newly generated transactions to the distributed ledger data (blockchain data). This process can employ well-known distributed ledger technology. By performing such processing, the transaction is approved, and the distributed ledger data shared by the multiple nodes that make up the distributed ledger is updated to new distributed ledger data with new blocks added. be.

[Information stored in distributed ledger]
As shown in FIG. 1, the distributed ledger stores battle record information 60, location information 61, and usage right information 62. FIG. These pieces of information can be obtained based on the transaction results indicated in the transactions of each block included in the distributed ledger data (see FIG. 4).

<Battle record information>
The track record information 60 is information for managing the track record of horse racing events. For example, the record information 60 indicates, for each horse, the result of the horse's race event. The results of the horse race event include race name, finish order, time, track condition, weather, race development, frame order, jockey, odds, and the like. In addition, the results of the horse race event include information on other horses that entered the race with the horse and results of confrontations between the horse and predetermined rival horses.

<location information>
The location information 61 is information for managing the location (owner and location) of the horse. For example, the location information 61 indicates, for each horse, the history of the current owner of the horse (the user who owns the horse), the history of the farm where the horse is raised, and the like. The horse owner history includes the current owner of the horse and previous owners of the horse. The history of the horse breeding farm includes the farm where the horse is currently bred and the farm where the horse was previously bred.

<Usage right information>
The usage right information 62 is information for managing usage rights related to stallion breeds. For example, the usage right information 62 indicates, for each stallion breed, the content of the usage right for the stallion, the user who has the usage right, and the like. As shown in FIG. 5, in this example, the usage right information 62 indicates, for each stallion breed, the number of times the usage right can be used and the user who has the usage right.

[Information stored in the storage unit of the server device]
As shown in FIG. 1, the storage unit 12 of the server device 10 stores horse characteristic information 51 and horse pedigree information 52 .

<Horse characteristics information>
The horse characteristic information 51 is information indicating characteristics of the horse. For example, the horse characteristic information 51 indicates the parameters of each horse. Examples of horse parameters include ability values, characteristics, aptitude, leg quality, temperament, growth type, age, appearance, motion (how to run), etc. Examples of ability values are reflected in race events. Speed, tenacity, momentum, strength, toughness, wisdom, etc.

<Horse pedigree information>
The horse pedigree information 52 is information for managing the pedigree (ancestor) of the horse. For example, the horse pedigree information 52 indicates, for each horse, a pedigree chart representing the ancestral relationship of the horse, characteristics of the pedigree of the horse, and the like.

The pedigree table included in the horse pedigree information 52 includes information on horses of each generation. For example, the pedigree is a 5-generation pedigree containing information on each generation of horses up to 5 generations before. This pedigree includes the female pedigree, which is the maternal pedigree. This pedigree also includes information on sibling horses on the same maternal side, information on horses that are close relatives, and the like.

In addition, there is a combination (blending theory) in the pedigree that greatly affects the parameters of the progeny. Examples of such combinations include in-bleed, out-bleed, line-bleed, nix, and the like. The horse pedigree information 52 includes information on such combinations (combination theory).

《Inbreed》
Inbreeding is a combination (combination of pedigree) in which the same ancestor exists up to five generations before in the pedigree chart. Inbreeding is sometimes referred to as cross, inbreeding, and the like. Inbreeding makes it possible to enrich the blood (characteristics, genes) of the same ancestral horse, making it easier to produce offspring that strongly inherit the ancestral horse's characteristics (such as abilities).

The horse pedigree information 52 also includes in-breed information indicating in which generation the blood of the same ancestral horse is included. For example, if a horse of the same ancestry is “horse A” and the horse’s blood is included in “four generations ago” and “three generations ago”, “horse A” and “4×3” are shown in association.

In-breed information also indicates the blood volume of horses of the same ancestry. For example, the blood volume of one generation ago is "50%", the blood volume of two generations ago is "25%", the blood volume of three generations ago is "12.5%", and the blood volume of four generations ago is "6. 25%”, and the blood volume five generations ago is set to “3.125%”. Then, if the blood of "horse A", which is a horse of the same ancestor, is included in "four generations ago" and "three generations ago", the blood volume of "horse A" is the blood volume of four generations ago. 6.25%" and the blood volume "12.5%" three generations before, which is the sum of "18.75%". The parameters of progeny are determined according to the blood volume of the same ancestral horse.

It should be noted that if the blood volume of horses of the same ancestry becomes too high, there is a high possibility that the formulation will be adversely affected. Examples of such adverse effects include decreased fertility rates, decreased birth success rates of progeny, deterioration of progeny parameters (eg, decreased physical strength), and the like. Considering the balance between the benefits and the negative effects of imbreeding, the case where the blood volume of horses of the same ancestry is "18.75%" is optimal.

《Outbleed》
Outbreeding is a combination (combination of pedigree) in which the same ancestor does not exist five generations earlier in the pedigree chart. Outbreeding avoids overblooding horses of the same ancestry.

《Line Bleed》
A linebreed is a combination (pedigree combination) of a stallion and a broodmare of the same strain. Line breeding is established even if there are no horses of the same ancestry five generations ago. The horse pedigree information 52 includes pedigree information indicating the pedigree of each generation of horses. For example, the name of the strain indicated in the strain information includes the name of the stallion that had a great influence on the performance of the offspring. Line breeding makes it easier to produce offspring that strongly inherit the characteristics (such as ability) of the horse's lineage.

"Knicks"
Knicks are combinations (combination of pedigree) that have a high possibility of producing excellent racehorses. The composition of the nix is determined in advance. In addition, the combination that becomes Knicks is updated based on statistics such as the performance (results) of progeny produced by the repeated combination.

Thus, the horse pedigree information 52 includes information on the above-described combination theory (combination of pedigree). This allows the user to select stallions and broodmares for breeding while examining the horse's pedigree. With such a combination, it is possible to produce offspring that inherit the characteristics of the ancestral horse (ability values, characteristics, aptitude, leg quality, temperament, growth type, age, appearance, motion (running style), etc.). By repeating these combinations, generations are repeated, and new combinations (combination of strains) appear in which progeny are active.

[Trading process]
Next, with reference to FIG. 6, trading processing performed in the game system of the first embodiment will be described. The trading process is a process for transferring the target of the trading from the seller user (seller user) to the buyer user (buyer user) and paying the price from the buyer user to the seller user. Targets for sale include the ownership of horses and the right to use stallions. In the following, a case where the object of sale is the "right of use" will be taken as an example.

<Step S11>
First, the purchaser user operates the game controller 33 and designates the license to be purchased. For example, the management unit 202 of the purchaser user's game device 20 displays an image of a trading screen on which the "utilization right to be sold" among the utilization rights indicated in the utilization right information 62 (see FIG. 5) is displayed on the display 31. to display. Then, the purchaser user inputs an operation to the game controller 33 for designating the usage right to be purchased from the trading screen.

<Step S12>
Next, the management unit 202 of the buyer user's game device 20 notifies the seller user who has the right of use that the buyer user wishes to purchase the right of use specified in step S11. For example, the usage right information 62 includes contact information (for example, IP address) for specifying the game device 20 of the seller user who has the usage right. Then, the management unit 202 of the buyer user's game device 20 refers to the contact information and transmits to the seller user's game device 20 purchase request information indicating that the buyer user wishes to purchase the right of use.

When the seller user agrees to the sale of the right of use in response to the request from the buyer user, the sale of the right of use is established. For example, when the management unit 202 of the seller user's game device 20 receives the purchase request information transmitted from the buyer user's game device 20, the display 31 displays an image indicating the purchase request information.

When the seller user agrees to the sale of the usage right, the seller user inputs an operation to the game controller 33 for agreeing to the sale of the usage right. The management unit 202 of the seller user's game device 20 responds to the operation, and transmits to the buyer user's game device 20 transaction consent information indicating that the seller user agrees to the transaction of the right of use. When the management unit 202 of the buyer user's game device 20 receives the sales consent information transmitted from the seller user's game device 20, the management unit 202 determines that the right to use has been sold.

Then, when the right to use is sold, the right to use is transferred from the seller user to the buyer user, and the price is paid from the buyer user to the seller user. In addition, the purchaser user is an example of a user who requested and was approved to use the right of use.

<Step S13>
Next, the management unit 202 of the buyer user's game device 20 performs ledger registration processing in order to register the result of the transaction established in step S12 in the distributed ledger. As a result, the result of the transaction that "the usage right specified in step S11 has been transferred from the seller user to the buyer user, and the price has been paid from the buyer user to the seller user" is registered in the distributed ledger. In addition, in Embodiment 1, along with the transfer of the usage right, the stallion breed that can be used by the usage right is also transferred.

In addition, in the trading process of the first embodiment, the trading (transferring) of the stallion breed may be performed instead of the trading (transferring) of the usage right. In this case, in the image of the trading screen displayed on the display 31 in step S11, instead of the "utilization rights that can be sold", "horse breeds that can be sold" are displayed. In this case, along with the transfer of the stallion breed, the right to use the stallion is also transferred.

[Running process]
Next, with reference to FIG. 7, the running process performed in the game system of Embodiment 1 will be described. The entry processing is processing for causing a racehorse to enter a race event. During the period before the start of the race event (specifically, during the reception period for the race event), the following processes are performed.

<Step S21>
First, a user who wants to run a racehorse in a race event operates the game controller 33 to specify a racehorse to run in the race event. For example, the management unit 202 of the game device 20 refers to the location information 61 and causes the display 31 to display an image of a race screen showing a racehorse owned by the user. Then, the user inputs an operation to the game controller 33 for designating a racehorse to run in the race event from the race screen.

Also, the user operates the game controller 33 to designate a jockey to ride the racehorse to be entered in the race event. For example, the user inputs an operation to the game controller 33 to designate a jockey.

<Step S22>
Next, the progress unit 201 of the game device 20 progresses the game so that the racehorse specified in step S21 will enter the race event. For example, the progression unit 201 detects the parameters of the racehorse specified in step S21 from among the horse characteristic information 51 stored in the storage unit 12 of the server device 10, and executes the race event according to the parameters of the racehorse. game data (game images and game sounds). Then, the progression unit 201 causes the display 31 and the speaker 32 to reproduce the game image and the game sound, respectively.

When the racehorse completes the race in the race event, the racehorse (specifically, the owner of the racehorse) is given a prize money (reward) according to the result of the racehorse in the race event. .

<Step S23>
Next, the management unit 202 performs ledger registration processing to register the results of the completed race event in step S23 in the distributed ledger. As a result, the results of the racehorse race event are registered in the distributed ledger. The results of the racehorse race event include the win or loss of the racehorse, the order of finish of the racehorse, the result of the confrontation with a predetermined rival (win or lose), the prize given to the racehorse, and the like.

[Stallion conversion process]
Next, referring to FIG. 8, the stallion conversion process performed in the game system of the first embodiment will be described. The stallion conversion process is a process for converting a racehorse into a stallion and generating a stallion type.

<Step S31>
The user operates the game controller 33 to designate a racehorse to be converted into a stallion. For example, the management unit 202 of the game device 20 refers to the location information 61 and causes the display 31 to display an image of a racehorse screen on which a racehorse owned by the user is posted. Then, the user inputs an operation to the game controller 33 for designating a racehorse to be converted into a stallion from the racehorse screen.

<Step S32>
Next, the generation unit 203 of the game device 20 generates a plurality of stallion breeds based on the racehorses specified in step S31. Each of the plurality of stallion breeds is a virtual medium consumed by utilization in compounding events. The number of stallion breeds generated based on racehorses is a predetermined number (in this example, the number of available usage rights). It should be noted that the number of stallion breeds generated based on the racehorse may vary depending on the parameters of the racehorse.

For example, the number of stallion breeds may be determined by lottery. In addition, the number of stallion breeds is based on the race results of the racehorses from which the racehorses are based, the age of the racehorses when they retire (i.e. when they become stallions), and the races of the racehorses. It may be determined according to the number of entries in the event, the pedigree of the stallion, or a combination thereof.

The stallion type generated by the generation unit 203 is given to the user who owned the racehorse from which the stallion type is based. In addition to granting the stallion breed, the generation unit 203 also grants the right to use the stallion to the user who owned the racehorse that is the source of the stallion breed. In addition, the racehorse from which the stallion breed is based cannot be used in the race event, and the ownership of the horse as a racehorse is extinguished. Also, a user who owned a racehorse that is the source of a stallion is given ownership of that horse as a stallion (stall). Thus, a stallion breed is generated based on the racehorse and the racehorse is converted into a stallion.

If there is a user who reserves the transfer of part (or all) of the stallion breed, the part (or all) of the stallion breed generated by the generation unit 203 can be used. granted to that user along with the rights. A user who reserves the transfer of some (or all) of a stallion is an example of a user who has requested and been approved to use a license.

<Step S33>
Next, the management unit 202 of the game device 20 performs ledger registration processing in order to register the result of the transaction (transfer of the usage right) established in step S23 in the distributed ledger. As a result, in the distributed ledger, "a plurality of stallion breeds and usage rights (utilization rights related to the stallion breeds) are generated based on the racehorses specified in step S31, and the usage rights for the generated stallion breeds are generated. It was granted to a predetermined user, the ownership of the horse as a racehorse was extinguished, and the ownership of the horse as a stallion (stall breed) was granted to the user (the user who owned the racehorse).” The result of the transaction is registered.

[Mare conversion process]
Next, with reference to FIG. 9, the filly conversion process performed in the game system of the first embodiment will be described. A mare conversion process is a process for converting a racemare into a broodmare. In other words, the mare conversion process is a process for converting the attributes of a mare from "a race mare available in a racing event" to "a broodmare available in a compounding event".

<Step S41>
The user operates the game controller 33 to designate a racemare to be converted into a broodmare. For example, the management unit 202 of the game device 20 refers to the location information 61 and causes the display 31 to display an image of a race mare screen on which a race mare owned by the user is posted. Then, the user inputs an operation to the game controller 33 for designating a racemare to be converted into a broodmare from the racemare screen.

<Step S42>
Next, the generation unit 203 of the game device 20 converts the designated racemare into a broodmare in step S41. In other words, the generation unit 203 converts the attribute of the mare specified in step S41 from "a race mare available in a race event" to "a broodmare available in a compounding event".

Ownership of the broodmare obtained by the conversion of the generation unit 203 is given to the owner of the racemare before being converted into the broodmare (user having ownership). In addition, the racemare before being converted into the broodmare is no longer available for use in racing events, and the horse's ownership as a racemare ceases. Also, a user who owned a racemare before being converted into a broodmare is given ownership of the horse as a broodmare.

<Step S43>
Next, the management unit 202 of the game device 20 performs ledger registration processing in order to register the result of the transaction (transfer of ownership) established in step S33 in the distributed ledger. As a result, in the distributed ledger, "the racemare specified in step S31 is converted to a broodmare, and the ownership of the broodmare is the owner of the racemare (the racemare before being converted to the broodmare) , the ownership of the racemare was extinguished, and the ownership of the horse as a broodmare was granted to the user (the user who owned the racemare)" is registered.

[Combination treatment]
Next, with reference to FIG. 10, the compounding process performed in the game system of Embodiment 1 will be described. A blending process is a process for producing offspring using a stallion breed and a broodmare. In a compounding event, the following processes are performed.

<Step S51>
A user who intends to make a combination operates the game controller 33 to specify the stallion type to be used in the combination event. For example, the management unit 202 of the game device 20 refers to the usage right information 62 and displays an image of a stallion screen on which a stallion owned by the user (specifically, a stallion to which the user has usage rights) is posted. 31. Then, the user inputs an operation to the game controller 33 for designating the stallion to be used in the combination event from the stallion screen.

Alternatively, the management unit 202 of the game device 20 displays an image of a purchase list including horse breeds available for purchase by the user (horse breeds not owned by the user) on the display 31 in response to the user's operation. to display. Then, the user inputs an operation to the game controller 33 for designating a stallion to be purchased from the purchase list for use in the compounding event. This allows the stallion breed to be purchased for use in the compounding event. The stallion breeds purchased at the blending event are then immediately available.

Also, the user who intends to mix operates the game controller 33 to specify the broodmare to be used in the mix event. For example, the management unit 202 of the game device 20 refers to the location information 61 and displays the image of the broodmare screen on which the broodmare owned by the user (specifically, the broodmare to which the user has ownership) is displayed on the display 31. to display. Then, the user inputs an operation to the game controller 33 for designating the broodmare to be used in the blending event from the broodmare screen.

Alternatively, the management unit 202 of the game device 20 causes the display 31 to display an image of a rental list listing broodmares that can be rented by the user (broodmares not owned by the user) in response to the user's operation. . Then, the user inputs an operation to the game controller 33 for designating a broodmare to be rented for use in the breeding event from the rental list. This allows the use of broodmares not owned by the user in the breeding event. A user who owns a broodmare that can be rented is paid by the user who rents the broodmare.

<Step S52>
Next, the generator 203 extracts information related to the stallion designated in step S51 from each of the horse characteristic information 51, the horse pedigree information 52, the battle record information 60, and the location information 61. FIG.

Specifically, from the horse characteristic information 51, the parameters of the racehorse, which is the basis of the stallion breed, are extracted. From the horse pedigree information 52, the pedigree table of the racehorse that is the source of the stallion breed, the characteristics of the pedigree of the racehorse, the information on the theory of the racehorse combination (combination of pedigree), and the like are extracted. From the battle record information 60, the results of the race event of the racehorse that is the source of the stallion breed, the results of the race event of the progeny generated using the stallion breed (specifically, the racehorse that grew from the progeny), etc. extracted. From the location information 61, the history of the owner of the racehorse that is the source of the stallion breed, the history of the ranch that breeds the racehorse, and the like are extracted.

Further, the generation unit 203 extracts information related to the broodmare designated in step S51 from each of the horse characteristic information 51, the horse pedigree information 52, the battle record information 60, and the location information 61.

Specifically, parameters of the broodmare are extracted from the horse characteristic information 51 . From the horse pedigree information 52, the pedigree table of the broodmare, the characteristics of the pedigree of the broodmare, information on the theory of the broodmare's combination (combination of pedigree), and the like are extracted. From the performance information 60, the results of the race event of the broodmare (specifically, the racemare before being converted to the broodmare), the results of the race event of the offspring generated using the broodmare, etc. are extracted. From the location information 61, the history of the owner of the broodmare, the history of the ranch that raises the broodmare, and the like are extracted.

The above extracted information is information that can be used to determine the parameters of progeny produced by blending.

<Step S53>
Next, based on the information obtained in step S52, the generating unit 203 generates progeny using the stallion and the broodmare. Stallion breeds are consumed by use. Also, the number of times the usage right for the stallion can be used is reduced by one.

The management unit 202 performs a ledger registration process in order to register in the distributed ledger that the stallion is consumed by use and the number of times the right of use is available has decreased by one. As a result, in the distributed ledger, the result of the transaction that "the stallion specified in step S51 is consumed by use, and the number of times the utilization right for that stallion can be used is reduced by one" is registered. As a result, the number of times the usage right can be used for the stallion type indicated in the usage right information 62 (the stallion type specified in step S51) is decremented by one.

Generation of progeny is affected by at least one piece of information obtained in step S52. Specifically, the generation unit 203 determines parameters of progeny based on at least one piece of information obtained in step S52.

For example, the generation unit 203 creates a progeny generation table that shows the correspondence relationship between "a combination of information obtained in step S52 (information that can be used to determine parameters of progeny generated by mixing)" and "parameters of progeny" have Then, the generation unit 203 detects the parameters of the progeny corresponding to the combination of information actually obtained in step S52 from the progeny generation table, and defines the detected progeny parameters as "generated by mixing". Decide on progeny parameters.

In this example, the production of progeny is affected by the outcome of a race event for a racehorse associated with the stallion breed specified in step S51. For example, the parameters of the progeny are determined (corrected) so that the better the result in the racing event of the racehorse, the better the parameters of the progeny.

Similarly, the generation of offspring is affected by the outcome of the race event of the broodmare (specifically, the racemare before being converted to a broodmare) designated in step S51. For example, the parameters of the offspring are determined (corrected) so that the better the performance of the race mare in the race event, the better the parameters of the offspring.

Also, some of the parameters (for example, "characteristics") of the racehorse related to the stallion breed designated in step S51 are carried over to the progeny generated using that stallion breed. For example, inheritance of such characteristics occurs with a predetermined probability of inheritance. Similarly, some of the broodmare's parameters specified in step S51 (eg, "characteristics") are inherited by offspring generated using that broodmare.

Also, generation of progeny is affected by the results of confrontations with rival racehorses associated with the stallion breed designated in step S51. For example, the parameters of the progeny are determined (corrected) so that the parameters of the progeny become better as the number of wins in confrontations with rivals increases. Similarly, it is affected by the result of the confrontation with the rival of the broodmare (specifically, the racemare before being converted to the broodmare) designated in step S51.

In addition, generation of offspring is affected by the relationship between the stallion breed and broodmare specified in step S51. For example, if there is a rivalry between a “race stallion related to the stallion breed” and a “race mare before being converted to a broodmare,” the offspring parameters are determined (corrected) so that the progeny parameters are good. ) is done.

In addition, generation of progeny is affected by the combination theory (combination of lines) established between the stallion breed and broodmare designated in step S51. For example, when inbreeding is established between a stallion and a broodmare, the parameters of progeny are determined (corrected) according to the blood volume of the same ancestral horse.

<Step S54>
Next, the generation unit 203 determines whether or not the blending (generation of progeny using the stallion and the broodmare) in step S53 has succeeded. If the combination in step S53 succeeds, the process of step S55 is performed, and if the combination in step S53 fails, the process of step S56 is performed.

<Step S55>
If the combination in step S53 succeeds, a progeny will be born. Ownership of a progeny is given to the owner of the broodmare used for generating the progeny (user having ownership of the broodmare). In addition, the progeny is placed in a ranch where the broodmare is raised, and raised in the ranch.

The management unit 202 adds information about the offspring to each of the horse characteristic information 51 and the horse pedigree information 52 . Specifically, parameters of progeny are added to the horse characteristic information 51 . A pedigree chart of progeny is added to the horse pedigree information 52 . Thus, the horse characteristic information 51 and the horse pedigree information 52 are updated.

In addition, the management unit 202 performs a ledger registration process in order to register the blending result in the distributed ledger. As a result, in the distributed ledger, "a progeny is born by combining the stallion species and broodmare specified in step S51, and the ownership of the progeny is the broodmare (breeding mare used to generate the progeny). Mare) is given to the owner, and the result "bred on the ranch where the broodmare is raised" is registered.

<Step S56>
On the other hand, if the combination in step S53 fails, no progeny will be born. In this case, the management unit 202 notifies the user that the combination in step S53 has failed. For example, the management unit 202 causes the display 31 to display an image indicating that the combination has failed.

[Value of stallion]
The value of a stallion is at least one of the achievements of the stallion in a compounding event, and the achievements of a progeny (specifically, a racehorse grown from a progeny) generated using the stallion in a race event. Varies depending on Specifically, the more a stallion's track record (eg, the number of times it is used) in a blending event, the higher the value of the stallion. Also, the greater the number of achievements (for example, the number of wins) in racing events of the progeny generated using the stallion, the higher the value of the stallion.

[Summary of Embodiment 1]
To summarize the above, the game program of the first embodiment causes the control unit 26 (computer) to function as the progression unit 201, the management unit 202, and the generation unit 203. FIG.

The progression unit 201 is a game that includes a race event (first event) that uses a racehorse (first virtual medium) and a compounding event (second event) that generates offspring (second virtual medium). progress. A progeny (second virtual medium) is a virtual medium generated using a stallion (material medium) related to a racehorse (first virtual medium) and a broodmare (third virtual medium).

Based on distributed ledger technology, the management unit 202 associates usage rights that allow the use of stallion breeds (material media) in breeding events (second events) with users who use the usage rights. The usage right is a right that has an upper limit on the number of available parameters and can be used individually by a plurality of users who have requested and been approved for usage.

In the compounding event (second event), the generation unit 203 generates a progeny (second virtual media). Generation of progeny (second virtual medium) is affected by game results in race events (first event) of racehorses (first virtual medium) related to stallion breeds (material medium).

[Effect of Embodiment 1]
As described above, in the first embodiment, by associating usage rights with users, transactions related to usage rights (for example, granting usage rights to users, buying and selling of usage rights between users, etc.) are managed using a distributed ledger. be able to.

In addition, by managing transactions related to usage rights with a distributed ledger, the reliability of transactions related to usage rights can be improved as compared to the case where transactions related to usage rights are managed in one place (for example, the server device 10).

Also, in Embodiment 1, the generation of progeny is influenced by game outcomes in race events for racehorses associated with the stallion breed. By doing so, it is possible to improve the interest of the game as compared with the case where the characteristics of the progeny are determined solely based on the characteristics of each of the stallion and the broodmare.

(Modification 1 of Embodiment 1)
FIG. 11 illustrates the configuration of the game system 1 of Modification 1 of Embodiment 1. As shown in FIG. The game system 1 of Modification 1 of Embodiment 1 differs from the game system 1 of Embodiment 1 in "operation of the management unit 202" and "information stored in the distributed ledger". Other configurations of the game system 1 of Modification 1 of Embodiment 1 are the same as those of the game system 1 of Embodiment 1. FIG.

In addition, as described above, the racehorse can obtain prize money (reward) in the race event. Specifically, a prize money (reward) according to the game result in the race event is given to the owner of the racehorse.

〔Management Department〕
In Modified Example 1 of Embodiment 1, the management unit 202 sets a plurality of users with "rights to receive rewards" related to racehorses. A racehorse remuneration right is the right to receive part of the remuneration earned by a racehorse. In addition, the management unit 202 associates a reward receipt right with a user who owns the reward receipt right based on distributed ledger technology. Specifically, when a transaction regarding the reward receipt right is established, the management unit 202 performs ledger registration processing to register the transaction result in the distributed ledger.

Further, as described above, the management unit 202 makes the user who has requested the use of the usage right consume a predetermined fee. Specifically, when the right to use is sold, the management unit 202 transfers the right to use from the seller to the buyer, and makes the buyer pay the price to the seller.

In Modified Example 1 of Embodiment 1, the management unit 202 sets a plurality of users with "rights to receive consideration" regarding usage rights. The right to receive consideration for the right to use is a right to receive part of the consideration for the transfer of the right to use (the consideration for the sale of the right to use). In addition, the management unit 202 associates the consideration receipt right with the user who owns the consideration receipt right based on the distributed ledger technology. Specifically, when a transaction regarding the consideration right is established, the management unit 202 performs ledger registration processing to register the result of the transaction in the distributed ledger.

In addition, in Modification 1 of Embodiment 1, usage rights are set for users who own compensation rights. Specifically, the right to receive consideration is accompanied by the right to use corresponding to the consideration that can be received by the right to receive consideration (the right to use that is exchanged for the consideration). The management unit 202 associates the user who owns the consideration right with the utilization right attached to the consideration right.

[Information stored in distributed ledger]
As shown in FIG. 11, in Modification 1 of Embodiment 1, the distributed ledger includes, in addition to battle record information 60, location information 61, and usage right information 62, remuneration right information 65 and consideration right information 66. memorize The remuneration entitlement information 65 and the consideration entitlement information 66 can be obtained based on the transaction results shown in the transactions of each block included in the distributed ledger data (see FIG. 4).

〈Information on remuneration rights〉
The reward receipt right information 65 is information for managing the reward receipt right. For example, the reward claim information 65 indicates, for each horse, the reward claim associated with the horse, the user who owns the reward claim, and the like.

〈Right of consideration information〉
The consideration receipt information 66 is information for managing consideration receipt rights. For example, the compensation entitlement information 66 indicates, for each stallion breed, the compensation entitlement associated with the stallion, the user who owns the compensation entitlement, and the like.

[Effect of Modification 1 of Embodiment 1]
As described above, in Modification 1 of Embodiment 1, multiple users can be motivated to play the game by setting reward receipt rights for multiple users.

In addition, in Modification 1 of Embodiment 1, it is possible to increase the willingness of a plurality of users to play the game by setting the payment receipt to a plurality of users.

(Modification 2 of Embodiment 1)
The game system 1 of Modification 2 of Embodiment 1 differs from the game system 1 of Embodiment 1 in the "success probability of compounding in the compounding event" and "generation of progeny in the compounding event". Other configurations of the game system 1 of Modification 2 of Embodiment 1 are the same as those of the game system 1 of Embodiment 1. FIG.

In Modified Example 2 of Embodiment 1, the probability of success in blending in a blending event changes according to the "passage of time" or the "number of times the stallion is used in the blending event." Specifically, the longer the time elapses, the lower the probability of successful blending in a blending event. Also, the more times a stallion breed is used in a blending event, the lower the probability of successful blending in the blending event.

In addition, in Modified Example 2 of Embodiment 1, generation of progeny in a compounding event is affected by the success probability of compounding in the compounding event. Specifically, when the success probability of combination in the combination event does not fall below the threshold, the first combination theory table (information table showing the correspondence between combinations of various information and progeny parameters) is used in the combination process. , the second blending theory table is used in the blending process if the probability of successful blending in the blending event is below a threshold. The second combination theory table is a special information table different from the first combination theory table (for example, an information table representing progeny mutation).

[Effect of Modification 2 of Embodiment 1]
As described above, in Modification 2 of Embodiment 1, by changing the probability of success of blending in a blending event according to the "passage of time" or the "number of times the stallion is used in the blending event", the decline of the stallion can be prevented. can be expressed. This makes it possible to improve the interest of the game.

Further, in Modified Example 2 of Embodiment 1, the generation of offspring in a blending event is affected by the success probability of the blending in the blending event, thereby expressing the mutation of the offspring caused by the decline of the stallion. can be done. This makes it possible to improve the interest of the game.

(Modification 3 of Embodiment 1)
The game system 1 according to Modification 3 of Embodiment 1 differs from the game system 1 according to Embodiment 1 in "settings related to usage rights" and "generation of progeny in a compounding event". Other configurations of the game system 1 of Modification 3 of Embodiment 1 are the same as those of the game system 1 of Embodiment 1. FIG.

In Modified Example 3 of Embodiment 1, the number of available usage rights is determined for each predetermined period (for example, every year). Specifically, for each predetermined period, the number of times of use of the right of use within the predetermined period is counted, and the number of times of use of the right of use within the predetermined period is a predetermined maximum number of times number of times equal to the number), the use of the right of use is prohibited within the predetermined period. For example, when the number of uses of the right to use the stallion A within a predetermined period reaches the upper limit, the use of the right to use the stallion A is prohibited within the predetermined period.

Further, in Modification 3 of Embodiment 1, the number of available usage rights in a compounding event changes according to the "passage of time" or the "number of times a stallion is used in a compounding event." Specifically, the longer the time passes, the fewer available parameters of usage rights in a compounding event. The more times a stallion breed is used in a breeding event, the fewer the available population of utilization rights in a breeding event.

In addition, in Modified Example 3 of Embodiment 1, generation of progeny in a compounding event is affected by available parameters of usage rights in the compounding event. Specifically, when the available parameter of the usage right in the compounding event does not fall below the threshold, the first compounding theory table (the information table indicating the correspondence between the combination of various information and the parameters of the progeny) is used in the compounding process. ) is used and the second blending theory table is used in the blending process if the available population of usage rights in the blending event is below the threshold. The second combination theory table is a special information table different from the first combination theory table (for example, an information table representing progeny mutation).

[Effect of Modification 3 of Embodiment 1]
As described above, in Modified Example 3 of Embodiment 1, by changing the available parameter of the usage right in the blending event according to the "passage of time" or the "number of uses of the stallion breed in the blending event," It can express the decline of the stallion. This makes it possible to improve the interest of the game.

In addition, in Modification 2 of Embodiment 1, the generation of offspring in a blending event is affected by the available parameter of the utilization right in the blending event, thereby suppressing the mutation of offspring caused by the decline of the stallion. can be expressed. This makes it possible to improve the interest of the game.

(Modification 4 of Embodiment 1)
The game system 1 of Modification 4 of Embodiment 1 differs from the game system 1 of Embodiment 1 in "racehorse parameters" and "racemare parameters". Other configurations of the game system 1 of Modification 4 of Embodiment 1 are the same as those of the game system 1 of Embodiment 1. FIG.

In Modification 4 of Embodiment 1, the parameters of the racehorse change over time. It should be noted that the parameters of the racehorse affect the game results in the race event. Specifically, the better the parameters of a racehorse, the better the game results in the race event for that racehorse.

Similarly, in Modification 4 of Embodiment 1, the parameters of the race mare change over time. It should be noted that the parameters of the race mare affect the game results in the race event. Specifically, the better the parameters of a racemare, the better the game results in the race event for that racemare.

[Effect of Modification 4 of Embodiment 1]
As described above, in Modification 4 of Embodiment 1, by changing the parameters of the racehorse (or racemare) over time, the decline due to aging of the racehorse (or racemare) can be expressed. can be done. This makes it possible to improve the interest of the game.

(Variation 5 of Embodiment 1)
The game system 1 of Modification 5 of Embodiment 1 differs from the game system 1 of Embodiment 1 in "handling of racehorses and stallions" and "handling of racehorses and broodmares." Other configurations of the game system 1 of Modification 5 of Embodiment 1 are the same as those of the game system 1 of Embodiment 1. FIG.

In Modified Example 5 of Embodiment 1, if the condition for disabling use of a racehorse is satisfied during a race event, that racehorse cannot be used in the race event Species) are subject to certain restrictions.

Examples of unusable conditions for racehorses include injuries, illnesses, and deaths of racehorses. Examples of predetermined restrictions on the use of stallion breeds in breeding events include prohibiting the use of stallion breeds in breeding events and increasing the incidence of deterioration (e.g. injury, illness, death, etc.) in progeny produced by breeding events. , a decrease in the probability of success in blending in a blending event, a decrease in the number of available parameters for utilization rights, and an increase in the incidence of deterioration of stallion breeds (for example, a decrease in the number of parameters and a decrease in the probability of success in blending).

Similarly, in Modified Example 5 of Embodiment 1, if the unusable condition for the race mare is established during the race event, the race mare becomes unusable in the race event, and the breeding mare in the compounding event (the race mare and associated broodmares) are subject to certain restrictions.

Examples of unusable conditions for racehorses include injuries, illnesses, and deaths of racemares. In addition, examples of predetermined restrictions on the use of broodmares in breeding events include prohibiting the use of broodmares in breeding events, increasing the incidence of deterioration of progeny produced by breeding events, and increasing the probability of successful breeding in breeding events. increased incidence of broodmare deterioration (e.g. reduced success rate of breeding).

[Effect of Modification 5 of Embodiment 1]
As described above, in Modified Example 5 of Embodiment 1, if the condition for disabling use of a racehorse is satisfied during a race event, the racehorse cannot be used in the race event, certain restrictions are imposed on the use of stallions associated with This makes it possible to express the deterioration of the racehorse (for example, injury, illness, death, etc.), thereby improving the interest of the game.

In addition, in the fifth modification of the first embodiment, when the unavailability condition for the race mare is established during the race event, the race mare becomes unusable in the race event, and the broodmare in the compounding event (related to the race mare Certain restrictions are placed on the availability of certain broodmares. This makes it possible to represent the deterioration of the race mare (for example, injury, illness, death, etc.), thereby improving the interest of the game.

(Modification 6 of Embodiment 1)
The game system 1 of Modification 6 of Embodiment 1 differs from the game system 1 of Embodiment 1 in "handling of stallions" and "handling of broodmares". Other configurations of the game system 1 of Modification 6 of Embodiment 1 are the same as those of the game system 1 of Embodiment 1. FIG.

In Modification 6 of Embodiment 1, if the condition for disabling use of a stallion breed is satisfied during a compounding event, that stallion breed is not allowed to be used in the compounding event. In addition, if a broodmare becomes unusable during a compounding event, the broodmare becomes unavailable for the compounding event.

Examples of unavailability conditions for stallion breeds include injuries, illnesses, and deaths of stallions (stallions) related to the stallion breed. Examples of unavailability conditions for broodmares include injury, illness or death of the broodmare.

[Modification 6 of Embodiment 1]
As described above, in Modification 6 of Embodiment 1, if the condition for disabling use of a stallion breed is met during a compounding event, that stallion breed is not available for the compounding event. This makes it possible to express the deterioration of the stallion (for example, injury, illness, death, etc.), thereby improving the interest of the game.

Further, in Modification 6 of Embodiment 1, if the unavailability condition is established for the broodmare during the compounding event, the broodmare becomes unavailable for the compounding event. This makes it possible to express the deterioration of the broodmare (for example, injury, illness, death, etc.), thereby improving the interest of the game.

(Modification 7 of Embodiment 1)
The game system 1 of Modification 7 of Embodiment 1 differs from the game system 1 of Embodiment 1 in the handling of virtual media. Other configurations of the game system 1 according to the seventh modification of the first embodiment are the same as those of the game system 1 according to the first embodiment.

In Modification 7 of Embodiment 1, at least one of a racehorse, a racemare, a stallion, a broodmare, and a progeny is replicable. Specifically, the generation unit 203 duplicates at least one of a racehorse, a racemare, a stallion, a broodmare, and a progeny in accordance with a user's instruction. Virtual media generated by duplication are subject to restrictions in the game.

Examples of restrictions on virtual media generated by duplication in games include prohibition of use in racing events (especially official games such as e-sports), prohibition of use in compounding events, and production created by compounding events. Examples include an increase in the rate of deterioration of pieces and a decrease in the success rate of combination in combination events.

[Effect of Modification 7 of Embodiment 1]
As described above, in the seventh modification of the first embodiment, the virtual medium generated by duplication is restricted in the game, thereby preventing the value of the original virtual medium from declining due to the duplication of the virtual medium. can be suppressed.

(Embodiment 2)
The game system 1 of Embodiment 2 differs from the game system 1 of Embodiment 1 in material media related to racehorses. Other configurations of the game system 1 of the second embodiment are the same as those of the game system 1 of the first embodiment.

As shown in FIG. 12, in Embodiment 2, the material medium associated with the racehorse is a stallion (stallion) permitted for use in a compounding event. This stallion (material medium) can be used the number of times corresponding to the number of uses of the right of use in the compounding event. Specifically, in the second embodiment, the generator 203 converts a racehorse into a stallion.

In Embodiment 2, the transfer of usage rights is done independently of the stallion. For example, when User A, who has the right of use with the number of times of use set to 10 times, transfers the "right of use with the number of times of use set to 5 times" to User B, the user A's right to use The number of possible uses is reduced from 10 to 5.

In addition, in the second embodiment, the "available parameter" of the usage right related to the stallion is the total number of usage times (in the stallion's lifetime possible number of times). Also, the total number of available times for all usage rights for a stallion is equal to the remaining number of total available times for the breeding event for that stallion.

[Usage right information]
As shown in FIG. 13, in the second embodiment, the usage right information 62 indicates, for each stallion, the number of times the stallion can be used and the user who has the usage right.

[Processing performed in the game system]
As in the first embodiment, in the game system of the second embodiment, trading processing, running processing, stallion conversion processing, mare conversion processing, and combination processing are performed. The trading process, the running process, and the mare conversion process of the second embodiment are the same as the trading process, the running process, and the mare conversion process of the first embodiment.

[Stallion conversion process]
Next, with reference to FIG. 14, the stallion conversion process of the second embodiment will be described.

<Step S35>
As in step S31, the user operates the game controller 33 to designate a racehorse to be converted into a stallion.

<Step S36>
Next, the generation unit 203 of the game device 20 converts the designated racehorse into a stallion in step S35. In other words, the generation unit 203 converts the attribute of the stallion specified in step S35 from "a racehorse available in a race event" to "a stallion available in a compounding event".

The ownership of the stallion converted from the racehorse by the generation unit 203 is given to the user who owned the racehorse before being converted into the stallion. In addition to granting ownership of the stallion, the generation unit 203 also grants the right to use the stallion to the user who owned the racehorse before being converted into the stallion. In addition, the racehorse from which the stallion is based cannot be used in the race event, and the ownership of the horse as a racehorse is extinguished.

Note that if there is a user who reserves the transfer of some (or all) of the usage rights related to the stallion, some (or all) of the usage rights related to the stallion converted from the racehorse by the generation unit 203 are Granted to the user. A user who reserves the transfer of some (or all) of the usage rights for a stallion is an example of a user who has requested and been approved to use the usage rights.

<Step S37>
Next, similarly to step S33, the management unit 202 of the game device 20 performs ledger registration processing in order to register the result of the transaction (transfer of usage right) established in step S23 in the distributed ledger. As a result, in the distributed ledger, "the racehorse specified in step S35 is converted to a stallion, the right to use the stallion is granted to a predetermined user, and the ownership of the stallion is the racehorse (the It is given to a user who owned a racehorse (the original racehorse of a stallion), and the result of the transaction that the ownership of that horse as a racehorse has disappeared is registered.

[Combination treatment]
The blending process of the second embodiment is similar to the blending process of the first embodiment shown in FIG. In the blending process of Embodiment 2, stallions are utilized instead of stallion breeds. In the blending process of Embodiment 2, a stallion and a broodmare are used to generate offspring.

<Step S51>
In step S51 of the second embodiment, a user who intends to mix operates the game controller 33 to designate a stallion (a stallion to which the user has the right to use) and a broodmare to be used in the mix event.

<Step S52>
In step S52 of Embodiment 2, the generation unit 203 generates information related to the stallion and broodmare designated in step S51 from each of the horse characteristic information 51, the horse pedigree information 52, the battle record information 60, and the location information 61. to extract

<Step S53>
In step S53 of the second embodiment, the generation unit 203 generates offspring using the stallion and broodmare based on the information obtained in step S52. Stallions are not consumed by use. Also, the number of times the stallion's usage right can be used is reduced by one.

The management unit 202 performs a ledger registration process in order to register in the distributed ledger that the number of times the usage right of the stallion can be used has decreased by one. As a result, the result of the transaction is registered in the distributed ledger that ``the stallion specified in step S51 is used for blending, and the number of times the usage right for the stallion can be used has decreased by one''. As a result, the number of times the usage right can be used for the stallion indicated in the usage right information 62 (the stallion specified in step S51) is decreased by one.

<Steps S54 to S56>
Steps S54 to S56 of the second embodiment are the same as steps S54 to S56 of the first embodiment.

[Effect of Embodiment 2]
In the game system 1 of Embodiment 2, the same effects as those of the game system 1 of Embodiment 1 can be obtained.

(Other embodiments)
In the above description, the case where the usage rights are granted in a lump in the stallion conversion process has been taken as an example, but the present invention is not limited to this. The right to use may be granted every predetermined period (for example, every year). In this case, when the total number of times that the usage rights can be used (for example, the total number of stallions) that are granted for each predetermined period reaches the "maximum number of usage rights that can be used", the grant of usage rights will end. may be Alternatively, when the number of arrivals of the predetermined period (the number of times the usage right is granted) reaches a predetermined number of times, the grant of the usage right may be terminated. The same is true for the stallions of the first embodiment.

With the above settings, it is possible to express the life span of a stallion. For example, when the total number of stallion breeds (or the number of times a stallion is granted) reaches a predetermined number, it reaches the end of its life as a stallion, the granting of the stallion related to that stallion ends, and the use of that stallion The grant of rights also terminates.

In addition, when the right to use is granted every predetermined period (for example, every year), the total number of times the right to use the right to be used may be the same or different. There may be. For example, as the number of arrivals of a predetermined period (the number of times of granting the right to use) increases, the total number of times that the right to use is granted during the predetermined period may decrease. The same is true for the stallions of the first embodiment.

With the above settings, it is possible to express the decline in fertility due to aging of the stallion. For example, as the age of the stallion increases, the number of stallion breeds granted during a predetermined period (a stallion related to the stallion) decreases, and the usage rights granted during the predetermined period (that stallion breed The total number of times available for usage rights related to

In addition, in the above description, the case where the usage right is "a right with a set number of times of usage" was taken as an example, but the present invention is not limited to this. For example, a usage right may be a right that is consumed by a single usage. In this case, the same number of usage rights as the available parameter of usage rights are granted.

Also, in the above description, a usage period may be set for the usage right. The right of use can be used within the available period of the right of use, and the right of use cannot be used outside the available period of the right of use. For example, if the usage right is granted every year, the usage period of the usage right may be set to one year from the date on which the usage right is granted.

Also, in the above description, an expiration date may be set for the usage right. When the usage right expires, the usage right can no longer be used. For example, the expiration date of the usage right may be set to the date when the stallion reaches the end of its life.

Also, in the above description, the case where the stallion is a virtual medium that is consumed by one use was taken as an example, but the present invention is not limited to this. For example, a stallion may be a virtual medium that is consumed by multiple uses. Specifically, the stallion may be a virtual medium with a set number of times it can be used. In this case, when a stallion is used once, the available number of times for that stallion is reduced by one. When the number of times a stallion can be used reaches zero, that stallion can no longer be used.

Further, in the above description, the owner of the stallion may be able to determine the distribution amount (issue amount) of the utilization right within a range not exceeding the upper limit. As a result, for example, it is possible to reduce the distribution volume of the exploitation right and increase the value of the exploitation right when excellent progeny are produced by the exploitation right.

In addition, in the above explanation, the smaller the number of times the utilization right is used (that is, the number of times the utilization right is used as a stallion) than the upper limit, the more advantageous the stallion utilized by the utilization right (the stallion related to the stallion breed) is in the game. It may be designed to be Examples of where the stallion is advantageous in the game are that the combination using the stallion makes it easier to produce excellent offspring (increases the probability of producing excellent offspring), and the fertilization of the combination using the stallion. The stallion's lifespan will be increased, and the stallion's maximum number of exploitation rights will not decrease over time.

In the above description, the users (players) who play the game include a user who is in charge of the owner of the racehorse, a user who is in charge of the breeder (for example, trainer) of the racehorse, and a user who operates the racehorse in the race event. Users in charge of operators (e.g. jockeys) who run horses, Users in charge of owners of stallions (or stallions), Users in charge of owners of race mares, Users in charge of breeders of race mares, In racing events At least one of a user responsible for manipulating a racemare, an owner of the broodmare may be included.

Also, in the above description, the example of the game played in the game system 1 is a "simulation game in which you can experience trading and breeding of horses in a virtual space", but the game is not limited to this.

For example, the above game may be a game in which a "game playing character" and a "training character" appear. In this game, the attribute of the character is converted from "for game play" to "for breeding". The character for game play is an example of a first virtual medium, and the character for breeding is an example of a material medium related to the first virtual medium.

Further, the above game may be a game in which an "active player character" and a "retired character" appear. In this game, the attribute of the character is changed from "active player" to "retired". The active player character is an example of a first virtual medium, and the retired character is an example of a material medium related to the first virtual medium.

Further, the above game may be a game in which "characters that can be assembled into a deck" and "characters that cannot be assembled into a deck" appear. In this game, the attribute of the character is changed from "deck formation possible" to "deck formation impossible". A character that can be decked is an example of a first virtual medium, and a character that cannot be decked is an example of a material medium related to the first virtual medium.

Also, in the above description, the case where the device used by the user is the game device 20 is taken as an example, but the device is not limited to this. For example, the device used by the user may be an information terminal such as a personal computer or a smart phone.

Even when these other embodiments are employed, the effects of the present invention are exhibited. Further, it is also possible to appropriately combine this embodiment with other embodiments, and other embodiments with each other. The above embodiments are essentially preferable illustrations, and are not intended to limit the scope of the present invention, its applications, or its uses.
