As a specific means for specifying a predetermined object as a specific object and a probability changing means for changing the winning probability value which is the probability that the specific object is won, the winning probability value is changed by the probability changing means. There are a plurality of possible objects, and the specific means identifies one or a plurality of objects as a part of the plurality of objects whose winning probability value can be changed as the specific object.

According to this game program, for example, when an item currently desired by the user is specified based on the game situation by a specific means, the winning probability value can be changed only for the item desired by the user. As a result, it is possible to suppress fluctuations in the value of the object as compared with the case where the winning probability value of the entire object in the game is changed.

Further, in the first invention, the game status monitored by the monitoring means is a display status of a predetermined game screen displayed on the display unit by the user's operation on the operation unit, and a user's operation on the operation unit. At least one of the execution status of a predetermined event in the game, the possession status of the object obtained by the user by the user's operation on the operation unit, and the selection status of the object selected by the user's operation on the operation unit. One may be included.

Further, in the first invention, the computer is further functioned as an object display means for displaying the object on the display unit by a user's operation on the operation unit, and the monitoring means is the display unit as the game situation. The display frequency value related to at least one of the display time and the number of display times displayed in is monitored for each object, and the specific means may specify the specific object based on the display frequency value. This makes it possible to identify, for example, an object that the user frequently sees as an item that the user wants.

Further, in the first invention, a quest execution means for executing a quest selected by a user's operation on the operation unit from a plurality of predetermined quests in the game, and execution of the computer. Further, as a lottery means for drawing the object to be given to the user from among a plurality of the objects predetermined for the quest based on the winning probability value when the quest is achieved. The monitoring means may be made to function, and the monitoring means may monitor the number of executions for each quest as the game situation, and the specific means may specify the specific object based on the number of executions of the quest. Thereby, for example, from the execution frequency of the quest selected and executed by the user, the object obtained by executing the quest can be specified as the object desired by the user.

Further, in the first invention, the monitoring means monitors an object owned by the user as the game situation, and the specific means may specify the specific object based on the object owned by the user. good. As a result, for example, from a weapon item owned by the user, a material item for strengthening the weapon item or an item compatible with the weapon item (for example, an armor item having the same type or attribute as the owned weapon item) can be selected by the user. Can be identified as the item that you want.

Further, in the first invention, the computer is further functioned as a character control means for controlling the behavior of a player character arranged in the space in the game based on the user's operation on the operation unit, and the user obtains the computer. A plurality of possible in-game objects include a plurality of equipment items that can be equipped by the player character, and a plurality of material items necessary for strengthening the equipment items, and the monitoring means can be used as the game situation. The equipment item owned by the user may be monitored, and the identification means may specify the material item necessary for strengthening the equipment item owned by the user as the specific object. As a result, it is possible to identify the material item necessary for strengthening the equipment item owned by the user, for example, the strengthening item that the user wants.

Further, in the first aspect of the present invention, the computer is designated as one or a plurality of objects according to the user's operation on the operation unit, and the specified object is stored in the storage unit as a wish list as a desired object designation means. Further functioning, the monitoring means monitors the object designated by the desired object designation means as the game situation, and the specific means is the specific means based on the object designated by the desired object designation means. You may specify the object. This makes it possible to reliably change the winning probability of the item that the user wants.

[Game overview]
The outline of the game in this embodiment will be described. The game according to the present embodiment is an action game in which a player character is made to act by a user's operation on a controller 31 in a three-dimensional virtual space representing a village, a forest, a plain, or the like to advance the game. Further, this game is a so-called multiplayer compatible game in which a plurality of users can participate, and is an online game in which a plurality of player characters corresponding to a plurality of users can act in the same virtual space.

In this game, various quests (missions, tasks) are prepared according to the progress. The quest can be ordered by the user operating and selecting the controller 31 from various quests displayed on the monitor 32. In the virtual space, there are order fields where you can receive orders for quests, such as villages and meetinghouses, and quest fields, such as forests and plains, which aim to achieve the ordered quests. The user can participate in a quest ordered by the user himself or a quest ordered by another user. The quest is started by receiving an order for a quest or participating in a quest, or by moving the player character P from the order field to the quest field after receiving an order for a quest or participating in a quest.

FIG. 2 shows an example of a game screen (quest screen) D1 showing how the player character P is located in the virtual space S (more specifically, the quest field). There are various types of quests, and quest fields are prepared according to the quest. Examples of quests include, as shown in Fig. 2, aiming to subdue enemy character (non-player character) N as a target placed in the quest field, and collecting predetermined items scattered in the quest field. There are things that aim for. The user operates the player character P and aims to complete the quest. When a quest is completed, the reward for that quest is given to the user. Here, "the reward is given to the user" means that the object that is the reward is associated (linked) with the save data (or account data) of the user.

Various items will appear in the virtual space S in this game. Specific examples of the items include material items that can be obtained in the quest and equipment items that can be equipped by the player character P. Hereinafter, material items and equipment items are also referred to as materials and equipment, respectively.

Equipment includes, for example, weapons and armor. The weapon is equipment for attacking the enemy character N, and more specifically, equipment for promoting a decrease in the physical strength gauge of the enemy character N when the player character P attacks the enemy character N. The armor is equipment for defending against the attack of the enemy character N, and more specifically, equipment for suppressing the decrease in the physical strength gauge of the player character P when the player character P is attacked by the enemy character N. ..

There are multiple types of equipment in this game. For example, weapons can be broadly divided into "melee weapons" that can attack enemy character N by approaching enemy character N to a certain short distance, and enemy character N that can attack enemy character N from a distance from enemy character N. It is divided into "distance weapons" which are weapons. There are various types of "melee weapons" such as large swords, swords, one-handed swords, twin swords, hammers, hunting whistles, lances, gun lances, slash axes, charge axes, and insect control clubs. In addition, there are types of "ranged weapons" such as light bow guns, heavy bow guns, and bows. Each of these 14 weapon types further includes a plurality of weapon types with different stats such as attack power and characteristics. Armor can also be divided into multiple types according to the type of weapon.

Equipment can be obtained by arranging the player character P in a predetermined equipment production area in the virtual space S called a "processing shop". More specifically, the processor can produce new equipment desired by the user or strengthen equipment already owned by the user. In this specification, the production and enhancement of equipment are collectively referred to as production. In order to make equipment at a processing shop, it is necessary to provide material items (materials) to the processing shop. Examples of the material include ores and gems, and leather, bones, nails, and scales of the defeated enemy character N. Materials can be obtained by collecting actions during the quest, for example, as a reward when completing the quest.

FIG. 3 shows an example of the game screen (quest reward screen) D2 displayed on the monitor when the quest is completed. On the quest reward screen D2, a plurality of reward slots C1 to C5 (five in the example) are displayed. The reward slots C1 to C4 show images E1 to E4 of the material acquired by completing the quest, respectively. A reward slot C5 with nothing shown inside indicates that the material corresponding to that slot was not acquired. By completing the quest, the user obtains a material item and creates a weapon. Users will use the new weapons they have created to challenge more difficult quests. Difficult quests provide high-value materials, allowing users to create even more powerful weapons with high-value materials.

The number of reward slots and the items obtained in each reward slot vary depending on the quest. In addition, the material as a reward for completing the quest is drawn from a plurality of types of materials according to the quest and given to the user. The winning probability value of each material is basically set in advance, and some of the materials are rare materials having a low winning probability value. For this reason, for example, a user may have to repeatedly challenge (execute) a quest for which a material can be obtained in order to obtain the rare material currently desired. In the game described in the present embodiment, the game situation generated by the user's operation is monitored, and the winning probability value of the item such as the material is changed according to the monitored game situation. Details of this will be described later.

[Functional configuration]

For example, by operating the controller 31, the user can move the player character P in the virtual space S, cause the player character P to attack the enemy character N, or use an item he or she owns. In addition to the player character P, non-player characters such as the enemy character N, which is the target of the quest, are also arranged in the virtual space S. The character control means 53 controls the operation of the non-player character in the virtual space S according to the situation of the game.

The object display means 54 causes the monitor 32 to display the item by the user's operation on the controller 31. This will be described with reference to FIG.

FIG. 5 is a diagram showing an example of the item selection screen D3. The item selection screen D3 is displayed on the monitor 32 by the user's operation on the controller 31. In this example, the item selection screen D3 makes it possible to confirm detailed information about one equipment selected by the user from a plurality of equipments. For example, the item selection screen D3 is displayed on the monitor 32 by causing the player character P to talk with the processor by the user's operation on the controller 31. The item selection screen D3 includes an equipment selection list display field F1, a selected equipment image display field F2, a selected equipment status display field F3, and a selected equipment required material display field F4.

In the equipment selection list display field F1, equipment that can be selected by the user's operation on the controller 31 is displayed. For example, a list of equipment owned by the user may be displayed in the equipment selection list display field F1. In the equipment selection list display field F1, some equipment among the equipment appearing in the game are displayed. For example, in the equipment selection list display field F1, equipment that can be obtained by strengthening the equipment currently owned by the user may be displayed. Alternatively, equipment that can be produced may be displayed in the equipment selection list display field F1. The equipment that can be produced and the equipment that can be enhanced may differ depending on the level of the player character P and the progress of the game.

Of the equipment displayed in the equipment selection list display field F1, one equipment is selected by the user's operation on the controller 31. In this example, the equipment selection list display field F1 displays the cursor F5 that can be moved on the list according to the user's operation on the controller 31. In this example, the cursor F5 is indicated by an arrow on the left side of the equipment, but the cursor F5 is any one that points to the equipment of 1 in the equipment selection list display field F1, such as a frame surrounding the equipment. It may be an embodiment.

The image of the equipment selected in the equipment selection list display field F1 is displayed in the selected equipment image display field F2.

The status of the equipment selected in the equipment selection list display field F1 is displayed in the selected equipment status display field F3. Equipment status includes, for example, the level and characteristics of the equipment, attack power if the equipment is a weapon, defense power if the equipment is armor, and so on. The characteristics of the equipment include, for example, attributes such as fire attribute and water attribute, and when the equipment is a weapon, a sharpness gauge showing a characteristic of reducing the attack power according to the number of attacks by the weapon.

In the equipment required material display field F4 being selected, the name of the material required to create the equipment selected in the equipment selection list display field F1 (hereinafter, also referred to as "necessary material") and the required number of each required material. Is displayed. For example, in the selected equipment required material display field F4, the materials required to enhance a certain equipment and create the selected equipment are displayed. The required materials vary depending on the equipment. In this way, the object display means 54 causes the monitor 32 to display the equipment item selected by the user's operation on the controller 31 and the required material of the equipment item. If the equipment currently owned by the user is displayed in the equipment selection list display field F1, the materials required to strengthen the equipment owned by the user are displayed in the selected equipment required material display field F4. You may.

Returning to FIGS. 4A and 4B, the quest execution means 55 executes a quest selected by the user's operation on the controller 31 from a plurality of predetermined quests in the game. Specifically, by arranging the player character P in the order field by the user's operation on the controller 31, the quest execution means 55 is a list of quests that can be ordered or a list of quests that other users have already ordered. Is displayed on the monitor 32 in a selectable manner. When one quest is selected from the quest list by the user's operation on the controller 31, the quest information is transmitted from the game device 2 to the server device 4. On the server device 4, the quest management means 72 receives the quest information, and registers and manages the quest ordered or participated by the user. In this way, the selected quest is executed.

The lottery means 56 draws one or a plurality of items from a plurality of predetermined items among the items appearing in the game, and executes a lottery event to be given to the user. For example, when the in-game quest executed by the quest execution means 55 is completed, the lottery means 56 has a plurality of items (equipment items and materials) predetermined for the quest, as shown in FIG. Items to be given to users are drawn as rewards from among items). The lottery by the lottery means 56 is executed based on the winning probability value stored in the storage unit 42, which will be described later.

The monitoring means 57 monitors the game status generated by the user's operation on the controller 31. The game status to be monitored by the monitoring means 57 can be an index for predicting the item that the user wants. In the present embodiment, the monitoring means 57 monitors the display frequency value for each weapon as a game situation generated by the user's operation on the controller 31. The display frequency value indicates how often information about each weapon is displayed on the monitor 32 (that is, how often the user is watching), and is at least one of the display time and the number of times each weapon is displayed on the monitor 32. is connected with.

For example, the monitoring means 57 monitors the display frequency value related to the display time and the number of times of display of the weapon displayed in the selected equipment image display field F2 of the item selection screen D3 by the object display means 54. In this example, the display frequency value is a value calculated by a predetermined formula using both the display time and the number of times of display of each weapon, but the display frequency value is the display time of each weapon displayed on the monitor 32. It may be itself, or it may be the number of times each weapon is displayed on the monitor 32 itself.

The specific means 58 identifies a predetermined material item as a specific object based on the game situation monitored by the monitoring means 57, that is, the display frequency value. The probability changing means 59 increases the winning probability value corresponding to the material item specified as the specific object by the specific means 58. The identification of the material by the specific means 58 and the change of the winning probability value corresponding to the specified material will be described with reference to FIG.

FIG. 6 is a chart showing an example of the display frequency value for each weapon and the winning probability value for each required material. In FIG. 6, a plurality of equipments appearing in the game are arranged in descending order of display frequency value (large sword B3, one-handed sword B8, bow B9, lance B12, charge ax B6, ...). In this example, the display frequency value of the large sword B3 is the highest. In other words, it is highly possible that the equipment that the user wants most is the Great Sword B3.

The specific means 58 identifies the necessary material as a specific object based on the display frequency value of the weapon monitored by the monitoring means 57.

Specifically, first, the specifying means 58 identifies one or a plurality of weapons as a desired object based on the display frequency value of the weapon. A desired object is an object that the user wants or is expected to want. In this example, the identification means 58 identifies the weapon with the highest display frequency value as a desired object. However, the specifying means 58 may specify a predetermined number of weapons as a desired object in descending order of display frequency value, or may specify a weapon whose display frequency value is equal to or higher than a predetermined threshold value as a desired object. ..

Next, the specifying means 58 specifies as a specific object the necessary materials necessary for producing the weapon specified as the desired object. In the figure example, the weapon with the highest display frequency value is the large sword B3, so the identification means 58 specifies the large sword B3 as a desired object. Further, since the materials required for producing the large sword B3 are the material M5, the material M30, and the material M19, the specifying means 58 specifies these materials M5, the material M30, and the material M19 as specific objects.

The winning probability value is the probability of winning by lottery by the lottery means 56. Specifically, the storage unit 23 of the game device 2 stores in advance a reference value of the winning probability of each item (hereinafter, referred to as a “reference probability value”). Basically, the lottery means 56 uses the reference probability value as the winning probability value to draw an item to be given to the user.

The reference probability values of the materials may be the same or different from each other. For example, the reference probability values of the material M5, the material M30, and the material M19 shown in FIG. 6 are 3%, 10%, and 15%, respectively. In the present embodiment, the winning probability value is the probability of winning in one lottery by the lottery means 56, in other words, the winning probability for each reward frame. When there are a plurality of reward slots (lottery slots) as in the example of FIG. 3, the lottery by the lottery means 56 is performed by the number of lottery slots. If the target material is not won in the lottery by the lottery means 56, other materials other than the target material are selected as rewards in the lottery slot, or nothing is selected and there is no reward in the lottery slot.

The probability changing means 59 changes the winning probability values of the materials M5, M30, and M19 specified as specific objects by the specific means 58. Specifically, the probability changing means 59 adds a predetermined additional probability value to the reference probability value of each material M5, M30, M19 by adding the winning probability value of the material M5, M30, M19 specified by the specific means 58. Change to the value. In this example, the additional probability values of the materials M5, M30, and M19 are set to 1%, 5%, and 5%, respectively. That is, the winning probability values of the materials M5, M30, and M19 specified by the specific means 58 are increased by the additional probability values by the probability changing means 59, respectively, as compared with before being specified as the specific object. Therefore, the winning probability values of the materials M5, M30, and M19 specified by the specific means 58 are 4%, 15%, and 20%, respectively.

The additional probability value may be a value corresponding to the reference probability value. For example, the lower the reference probability value of the specified material, the lower the additional probability value of the material may be set. Further, the additional probability value may be set so as to increase in descending order of the display frequency value.

Next, in the present embodiment, the winning probability changing process executed by the monitoring means 57, the specifying means 58, and the probability changing means 59 will be described with reference to FIG. 7. When the game is started, the monitoring means 57 starts monitoring the game status generated by the user's operation on the controller 31 (step S1). In this example, the monitoring means 57 monitors the display frequency value of the weapon displayed on the monitor 32 (for example, the selected equipment image display field F2) by the object display means 54 for each weapon.

Next, the specific means 58 identifies a predetermined necessary material as a specific object based on the game situation monitored by the monitoring means 57, that is, the display frequency value of the weapon (step S2). The probability changing means 59 changes the winning probability value corresponding to the required material specified as the specific object by the specific means 58 (step S3). The winning probability change process may be executed at a predetermined cycle during the game, and each time the game status to be monitored changes by the user operation (in this example, the weapon is displayed and displayed on the monitor 32). It may be executed (every time the frequency value changes).

Summarizing the above, the game program 34a according to the present embodiment includes a monitor 32 (display unit) on which the game screen is displayed, a controller 31 (operation unit) operated by the user, and a control unit 21 (computer). In the game system provided, the game program executed by the control unit 21 is monitored by the monitoring means 57 and the monitoring means 57 that monitor the game status generated by the user's operation on the controller 31. Based on the above-mentioned game situation, the specific means 58 for specifying a predetermined material item (object) as a specific object from the in-game items available to the user, and the winning probability value at which the specific object is won are changed. There are a plurality of material items whose winning probability value can be changed by the probability changing means 59, and the specific means 58 is a plurality of material items whose winning probability value can be changed. One or more material items that are a part of the inside are specified as the specific item.

Weapons with higher display frequency values are more likely to be the weapons that the user wants, and therefore it is predicted that the user also wants the necessary materials for weapons with higher display frequency values. Therefore, according to this game program 34a, it is possible to change the winning probability value of the item predicted to be desired by the user. As a result, it is possible to suppress fluctuations in the value of the material item as compared with the case of changing the winning probability value of the entire material item in the game.

Next, the game program and the game system according to the second embodiment will be described with reference to FIGS. 8 and 9. In the following description of the second and third embodiments, the differences from the first embodiment will be mainly described, and the same components will be designated by the same reference numerals and description thereof will be omitted.

FIG. 8 is a block diagram showing a functional configuration of the game device 2 and the server device 4 in the second embodiment. Also in the present embodiment, as in the first embodiment, the monitoring means 57 monitors the display frequency value of the equipment item as a game situation generated by the user's operation on the controller 31. In the present embodiment, as shown in FIG. 8, in the present embodiment, the specific means 58 includes the first specific means 58a and the second specific means 58b. Further, the game device 2 (control unit 21) also functions as the desired object designation means 60. The desired object designation means 60 will be described in the third embodiment.

Similar to the first embodiment, the first specific means 58a identifies one or a plurality of weapons as the first desired object, and further, the specified weapon as the first desired object, based on the display frequency value of the weapon. The necessary material required for production is specified as the first specific object. Explaining using the example of FIG. 6, the first specifying means 58a identifies the large sword B3, which is the weapon with the highest display frequency value, as the first desired object, and further, the material necessary for producing the large sword B3. The materials M5, M30, and M19 are specified as the first specific object.

The second specifying means 58b identifies one or more weapons as the first seeking object based on the display frequency value of the weapon, and further, the weapon derived from the weapon specified as the first seeking object is the second seeking object. Specify as. Then, the second specific means 58b specifies the necessary material of the weapon specified as the second desired object as the second specific object. This will be described with reference to FIG.

FIG. 9 is a diagram showing an example of the derived route screen D4 of the equipment item. The derivative route screen D4 is a game screen that shows in a bifurcation diagram that new equipment is derivatively created by strengthening a certain equipment. That is, in the example shown in FIG. 9, the derivative route screen D4 for the large sword B1 is shown. In the example, for example, the route from the large sword B1 to the large sword B2 shows that it is possible to produce the large sword B2 by strengthening the large sword B1. In addition, the route extending from the Great Sword B2 branches off to the Great Sword B3, the Great Sword B7, and the Great Sword B8. This shows that by strengthening the Great Sword B2, it is possible to create the Great Sword B3, the Great Sword B7, or the Great Sword B8 according to the user's choice.

For example, as in the example of FIG. 6, if the display frequency value of the large sword B3 is the highest, not only the user may want the large sword B3, but also the large sword B3 is strengthened after the user obtains the large sword B3. It can be said that there is a high possibility that they want to let them do it. In other words, it is likely that the user wants not only the Great Sword B3, but also the Great Sword B4, Great Sword B5 or Great Sword B6 and the materials needed to make them (or after getting the Great Sword B3). It can be said that. Therefore, the second specific means 58b is the equipment produced from the equipment (large sword B3) specified as the first desired object (large sword B4, large sword B5, and large sword B6 surrounded by a broken line in FIG. 9). In other words, the equipment on the downstream side of the derived route is specified as the second desire object from the equipment specified as the first desire object. Then, the second specifying means 58b specifies as the second specific object the material necessary for producing those equipments specified as the second desired object.

The probability changing means 59 increases the winning probability value corresponding to the first specific object specified by the first specific means 58a, and increases the winning probability value corresponding to the second specific object specified by the second specific means 58b. Raise it.

Also in this embodiment, the same effect as that of the first embodiment can be obtained.

<Third Embodiment>
Next, the game program and the game system according to the third embodiment will be described with reference to FIG. The functional configuration of the game device 2 and the server device 4 in the third embodiment is the same as the functional configuration of the game device 2 and the server device 4 in the second embodiment shown in FIG.

In the present embodiment, the monitoring means 57 monitors the item designated by the desired object designation means 60 instead of the display frequency value. Then, the first specific means 58a and the second specific means 58b specify the first specific object and the second specific object, respectively, based on the items designated by the desired object designation means 60. This embodiment differs from the second embodiment in this respect.

The desired object designation means 60 designates one or a plurality of items according to the user's operation on the controller 31, and stores the list of the designated items in the storage unit 23 as the wish list information. That is, in the present embodiment, the item currently desired by the user can be registered as a wish list.

FIG. 10 is a diagram showing an example of the wish list screen D5. The wish list screen D5 is displayed on the monitor 32 by the user's operation on the controller 31. In this example, the wish list screen D5 displays a list of equipment registered as the equipment desired by the user. For example, the wish list screen D5 includes a wish list display column G1 and a selected equipment required material display column G2.

In the wish list display field G1, a list of desired equipment registered in advance by the user is displayed. Of the equipment displayed in the wish list display field G1, one equipment is selected by the user's operation on the controller 31. In this example, the wish list display field G1 displays the cursor G3 that can be moved on the list according to the user's operation on the controller 31. Like the cursor F5 in FIG. 5, the cursor G3 may be in any form as long as it points to the equipment of 1 in the wish list display field G1. Since the selected equipment required material display field G2 shows the same contents as the selected equipment required material display field F4, the description thereof is omitted.

The monitoring means 57 monitors the item displayed in the wish list display field G1 designated by the desired object designation means 60, that is, the wish list information stored in the storage unit 23. Then, the first specific means 58a is necessary to specify the item (large sword B3 and bow B9 in the figure) designated by the desired object designation means 60 as the first desired object and to create the first desired object. Material items (for example, materials M5, M30, M19 that are necessary materials for the big sword B3) are specified as the first specific object.

Further, the second specific means 58b identifies one or a plurality of weapons as the first desired object based on the weapon designated by the desired object designation means 60, and is further derived from the weapon specified as the first desired object. Specify the weapon to be used as the second desired object. Then, the second specific means 58b specifies the necessary material of the weapon specified as the second desired object as the second specific object.

The probability changing means 59 increases the winning probability value corresponding to the first specific object specified by the first specific means 58a, and increases the winning probability value corresponding to the second specific object specified by the second specific means 58b. Raise it.

Also in this embodiment, the same effects as those in the first and second embodiments can be obtained. Further, the item specified based on the display frequency value is not necessarily the item desired by the user, but the item in the wish list is an item designated as the item desired by the user himself / herself. Therefore, in the present embodiment, it is possible to surely change the winning probability of the item desired by the user.

<Other embodiments>
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

For example, the game program 34a may not be recorded in the game media 34, and may be downloaded from the outside to the game device 2 via the communication network NW, for example. For example, the game device 2 included in the game system of the present invention may be a mobile information terminal such as a smartphone, and the operation unit and the display unit may be a touch screen or the like. Further, the display device for displaying the game screen may be a head-mounted display or the like.

Further, in the above embodiment, the game system 1 includes the game device 2 and the server device 4, but the game system of the present invention may be configured not to include the server device 4. The present invention is applicable not only to online games but also to offline games.

Further, the server control unit 41 of the server device 4 may play a part of the function of the control unit 21 described in the above embodiment. For example, in the first embodiment, the control unit 21 of the game device 2 functions as a lottery means 56, a monitoring means 57, a specific means 58, and a probability changing means 59 by executing the game program 34a, but the server. The server control unit 41 of the device 4 may execute a part or all of these functional units 56 to 58 by executing the game program stored in the storage unit 42. In this case, the game program of the present invention is distributed and stored in the game device 2 and the server device 4, and the control unit 21 and the server control unit 41 that execute such a game program execute the game program "computer". Corresponds to.

The winning probability value may not be stored in the storage unit 23 of the game device 2, and may be stored in the storage unit 42 of the server device 4, for example. For example, the reference probability value of each object described in the above embodiment is stored in the storage unit 42 of the server device 4, and the additional probability value added to the reference probability value by the probability changing means 59 is stored in the game device 2. It may be stored in part 23. The "storage unit" of the present invention may include not only the storage unit 23 of the game device 2 but also the game media 34, or may include the storage unit 42 of the server device 4.

In addition, the first to third embodiments can be combined as appropriate. For example, in the second embodiment, the monitoring means 57 may monitor both the display frequency value for each weapon and the item designated by the desired object designating means 60, and the monitoring means 57 may monitor both the first specifying means 58a and the second specifying means. 58b may specify the first specific object and the second specific object, respectively, based on the item designated by the desired object designation means 60 as well as the display frequency value for each weapon. Further, in the second and third embodiments, the specific means 58 may include only one of the first specific means 58a and the second specific means 58b, and may not include the other.

Further, the monitoring means 57 monitors the display frequency value of each item and the item designated by the desired object designation means 60 as the game status, but the game status as the monitoring target of the monitoring means 57 is not limited to this. For example, the game status monitored by the monitoring means includes the display status of a predetermined game screen displayed on the display unit by the user's operation on the operation unit (for example, the display frequency value for each object described above), and the user's operation unit. At least one of the execution status of a predetermined event in the game by the operation, the possession status of the object obtained by the user by the user's operation on the operation unit, and the selection status of the object selected by the user's operation on the operation unit. May include. By monitoring these game situations, it is possible to easily identify or predict the object that the user wants.

For example, the monitoring means 57 may monitor the number of executions of each quest, which is a predetermined event in the game, as the execution status of a predetermined event in the game by the user's operation on the operation unit. The identification means 58 may specify a predetermined item based on the number of times the quest is executed monitored by the monitoring means 57. Specifically, the specifying means 58 identifies one or a plurality of quests in descending order of the number of times the quest is executed, based on the number of times the quest is executed monitored by the monitoring means 57. For example, the specifying means 58 may specify one or a plurality of quests whose number of executions exceeds a predetermined number of times, or may specify a predetermined number of quests in descending order of the number of times of quest execution. Then, the specific means 58 may specify the item available in the specified quest as a specific object, and the probability changing means 59 may change the winning probability value of the item in the quest.

Further, for example, the monitoring means 57 may monitor the object owned by the user as the possession status of the object acquired by the user by the user's operation on the operation unit. The identification means 58 may specify a predetermined item as a specific object based on the object owned by the user. Specifically, the identification means 58 may specify a material item necessary for strengthening an equipment item owned by the user as a specific object. Further, the specifying means 58 may exclude the same object as the object owned by the user (for example, an equipment item) from the target specified as the specific object.

Further, for example, the monitoring means 57 may monitor the equipment item equipped on the player character P operated by the user as the selection status of the object selected by the user's operation on the operation unit. The specifying means 58 may specify a predetermined object related to the equipment item equipped on the player character P as a specific object. For example, the specifying means 58 may specify a material item necessary for strengthening the equipment item equipped on the player character P as a specific object. Further, the specifying means 58 may specify armor of the same type (for example, the same attribute) as the weapon equipped on the player character P as a specific object.

In the above embodiment, the monitoring means 57 monitors the display frequency value for each weapon as the display status of the predetermined game screen, but the monitoring means 57 may monitor the display frequency value for each material.

The present invention can also be applied to a game in which a weapon or the like that one does not possess cannot be displayed on the game screen according to the user's selection. For example, in an online game, in the case of a game in which the player character information of another user can be displayed on the game screen according to the user's selection, the monitoring means 57 sets the display status of the predetermined game screen as the player character of the other user. The number of times the equipment, characters, etc. worn by the player are displayed may be monitored as a display frequency value. Items worn by other users' player characters may be specified as items that the user wants.

Further, the game situation monitored by the monitoring means 57 may be one or a combination of a plurality of the above-exemplified game situations. For example, the monitoring means 57 may monitor both the display frequency value of each item and the number of times the quest is executed, based on both the display frequency value of each item monitored by the monitoring means 57 and the number of times the quest is executed. A given item may be specified. Further, the monitoring means 57 may monitor a game situation other than the above as a game situation generated by the user's operation on the controller 31. For example, in the case of a game in which the user can select whether the item given to the user by the lottery event in the game is satisfied or dissatisfied by the user's operation on the controller 31, the monitoring means 57 selects the selection in the game status. May be monitored as.

In the above embodiment, a learning function such as deep learning may be used to specify a specific object by a specific means. For example, for a large number of users, data showing the game status of each user and data on items obtained by each user are accumulated, and a machine-learned prediction model is constructed using these as teacher data, and the specific means is constructed. From the game situation monitored by the monitoring means 57, an item that the user should obtain or is effective for the user may be predicted and specified as a specific object by using the prediction model. As a result, even if the user does not actually want it, the necessary material for creating a weapon necessary for the user (for example, a weapon effective for a quest that the user cannot clear) may be specified from the game situation.

Further, in the above embodiment, the winning probability value of the material item is changed, but the winning probability value of the item other than the material item may be changed. For example, the specific means may change the winning probability value of the weapon itself specified as the desired object, instead of the winning probability value of the material required for producing the weapon specified as the desired object.

Specifically, in the above embodiment, the identification means 58 is necessary to identify a desired object (for example, a weapon) that the user wants or is expected to want, and obtains the desired object. An object (for example, a necessary material) is specified as a specific object, but the method of specifying a specific object by a specific means is not limited to this. For example, the specific means may specify the desired object itself specified based on the game situation monitored by the monitoring means as the specific object. For example, in a game in which a reference probability value is set for each weapon and the weapon itself can be won in an in-game lottery event, the specific means is one or more based on the display frequency value of the weapon monitored by the monitoring means. Weapon itself (for example, the weapon with the highest display frequency value) may be specified as a specific object. Then, the probability changing means may change the winning probability of the weapon specified as the specific object to a value obtained by adding a predetermined additional probability value to the reference probability value.

Further, the probability changing means may change the winning probability value other than items such as weapons, armor, and materials. That is, the "object" in the present invention may be any object that can be owned by the user, and may be, for example, a character, an animal, a monster, or a card expressing them.

Further, the object whose winning probability value can be changed (in other words, the object specified by the specific means or the object as a candidate) does not have to be all the objects in the game available to the user. Objects whose winning probability value can be changed may be limited to objects that are relatively difficult to obtain, such as rare items (for example, objects having a winning probability of less than or equal to a predetermined setting probability).

In the above embodiment, the winning probability value is described as the probability of winning in one lottery by the lottery means 56 (winning probability for each lottery frame), but the winning probability value is not limited to this. The winning probability value may be any probability that the specific object is won (the probability that the user obtains the specific object). For example, in the above embodiment, an example in which the winning probability value is stored in the storage unit for each object in the game available to the user has been described, but the winning probability value is stored in the storage unit 23 for each object. It does not have to be. For example, the winning probability value may not be a value directly changed by the probability changing means, but may be a value indirectly changed. For example, the probability changing means does not change the probability of winning in one lottery by the lottery means 56, and does not change the one-time winning probability of the specific object in each lottery frame shown in FIG. By increasing the number, the probability that a specific object will be won may be increased as a result. Further, the probability changing means may increase both the lottery slot and the winning probability of each lottery slot. For example, in the case of a game in which an item appears as a sale item in a weapon shop or a tool shop arranged in a virtual space, the winning probability value may be the probability that the item appears as a sale item.

Further, the probability changing means may change the purchase cost of an item that increases the probability of winning in one lottery by the lottery means 56. The probability changing means may change the purchase cost for obtaining the specific object, or the price such as the processing cost and the modification cost.

The lottery means 56 does not have to be a lottery of items given to the user when the in-game quest executed by the quest execution means 55 is completed, and for example, a predetermined item (medal) or the like is consumed. Then, a lottery event for drawing an item to be given to the user may be executed.

Further, in the above embodiment, the probability changing means 59 increases the winning probability value, but the winning probability value may be decreased. As a result, it is possible to increase the degree of familiarity of the user with the game, increase the rarity of the user who has obtained the desired item, and satisfy the user's desire for self-revealing.
