  The personal point 611 is an example of an event point. The personal point 611 is a case where, in an event of growing a plant during a certain period, when a player grows a seed of a specific plant owned and grows to a specific plant, that is, a specific item is changed to another item. In some cases, it is given to the player. As a specific plant species, for example, a plant species having a rarity degree equal to or higher than a predetermined value is preset. The acquired prize 612 is an item given to the player when the player acquires the personal points 611 at a predetermined value or more in the above event.

  The group point 613 is another example of the event point. The group points 613 are the sum of the individual points of the player and the friend points of the player. That is, a group is a set composed of a player and a friend player of the player. The group point is given to the player when the player grows a specific plant seed owned by the friend player in the garden of the friend player (that is, according to a request from the player) and grows into a specific plant. May be. The group point is given to the player when the friend player (that is, in accordance with a request from the friend player) grows a specific plant seed owned by the player in the player's garden and grows it into a specific plant. May be. The acquired prize 614 is an item given to the player when the player acquires the group point 613 at a predetermined value or more in the above event.

  FIG. 6C is a diagram illustrating an example of an item use screen displayed on the display unit 24 of the mobile terminal 2.

  The item use screen 620 shown in FIG. 6C is displayed when the “use item” button 603 is pressed on the My Page screen 600. An image 621 of the player's garden is displayed on the upper side of the item use screen 620, and an input field 622 for designating a position where the item is arranged is displayed in the center.

The area where the item is arranged by the operation of directly pressing the specific area in the image 621 instead of displaying the number of each area on the image 621 and the player selecting the specific area number in the input field 622. May be selected. Further, the player can provide the selected item (plant seed) to the friend player by selecting the radio button 625 of the specific item and pressing the “present” button 627.

  FIG. 7A is a diagram illustrating an example of a lottery screen displayed on the display unit 24 of the mobile terminal 2.

  The lottery screen 700 shown in FIG. 7A is displayed when the “lottery” button 606 is pressed on the My Page screen 600. On the upper side of the lottery screen 700, the number of possible lotteries 701, the current rank 702 of the player, the event points 703 necessary for going up to the next rank, the explanation 704, and the explanation 705 are displayed. In addition, for each lottery target item, an image 706, a name 707, a winning probability 708 at the current rank, and a winning probability 709 at the next rank are displayed for each lottery target item. A “Yes” button 710 is displayed.

  In this game, the player can draw a predetermined number of times (for example, twice) for a certain period (for example, one day), and the remaining number of times that the player can perform the lottery within the certain period is set as the number of times 701 that can be drawn. Is displayed. The current rank 702 is determined according to the event point. For example, the current rank 702 is directly proportional to the event point, and is higher as the event point is higher and lower as the event point is lower. For example, ranks are classified into 1 to 10, players with event points from 0 to 99 are classified as rank 1, players with income points from 100 to 199 are classified as rank 2, and players with income points of 90 or more are ranked as 10. It is divided.

  In this game, a plurality of items are set in advance as the lottery target items, and the winning probability is associated with each lottery target item. On the lottery screen 700, all preset lottery target items are displayed together with their winning probabilities. The description 704 describes that a winning probability is set for each item and that all items can be acquired by one lottery. By displaying a plurality of lottery target items side by side and displaying that all items can be acquired, the player can obtain a sense of expectation that many items may be acquired.

  The winning probability 708 is the winning probability at the current rank 702 of each player. In this game, the winning probability of each lottery item is changed based on the rank 702 of each player, and the higher the rank 702, the lower the rank 702. Therefore, the player can easily recognize his / her rank in the event based on the winning probability of each lottery item. Furthermore, the player can realize that the effect of increasing the winning probability has been obtained by the points acquired through efforts in the event. The winning probability 709 is a winning probability when each player goes up to the next rank. By displaying the winning probability 709 in the next rank, it is possible to improve the player's willingness to increase the rank and activate the event.

  The explanation 705 describes that the higher the event point, the higher the winning probability. As a result, the player's willingness to acquire many event points can be improved, and the event can be activated. Further, as described above, since the number of times that the player can perform the lottery is limited, it is possible to improve the player's willingness to acquire event points at an earlier stage, and to activate the event. It becomes possible to make it. The player can request the execution of the lottery by pressing the “Lottery” button 708.

  For example, an item used in a game is set as the lottery target item. Note that an item used in an event may be set as the lottery target item, and the lottery target item may be changed for each event. Moreover, the item which can acquire an event point by using as a lottery object may be set. Thereby, even a player who cannot acquire an event point in an event can acquire an event point through a lottery, increase the winning probability of the lottery target item, and efficiently acquire the lottery target item.

  The winning probability of each item is not uniformly changed based on the rank 702 of each player, but an item whose winning probability is changed based on the rank 702 may be selected according to an instruction from the player. .

  FIG. 7B is a diagram illustrating an example of the winning probability change screen displayed on the display unit 24 of the mobile terminal 2.

  The winning probability change screen 720 shown in FIG. 7B is displayed, for example, when the rank of the player is increased. On the upper side of the winning probability change screen 720, the total increase rate 721 of the winning probability that can be increased by raising the rank of the player is displayed. Below that, for each lottery item, an image 722 of each lottery item, a name 723, an input field 724 for inputting an increase rate of the winning probability, and a “setting” button 725 are displayed. Is done. In the input field 724 for each lottery item, the player inputs the rate of increase so that the sum of the rates of increase is equal to or less than the total rate of increase 721, and further presses the “SET” button 725 to change the winning probability. You can select items and increase the winning probability. Thereby, each player can strategically set an item to be acquired according to his level, hobbies, and the like.

  FIG. 7C is a diagram illustrating an example of a lottery result screen displayed on the display unit 24 of the mobile terminal 2.

  The lottery result screen 730 shown in FIG. 7C is displayed when the “Lottery” button 710 is pressed on the lottery screen 700. On the lottery result screen 730, for each item won by lottery, an image 731 of each item, a name 732, and a “use” button 733 are displayed.

  The items won by lottery are displayed side by side in descending order of rarity. Thereby, when a player acquires an item with high rare value, it becomes possible to make an item with high rare value stand out, and the player can recognize intuitively that an item with high rare value was acquired. Alternatively, the items won by lottery may be displayed side by side in ascending order of rarity. In that case, the player cannot immediately recognize whether or not an item with a high rare value has been acquired, and the player's feeling of thrill and expectation can be enhanced.

  Further, the items won by lottery may be displayed side by side in ascending order of the number of users owned. In this case, the player can intuitively recognize that an item that he / she does not own or an item he / she has little is acquired. Moreover, the display form of the item displayed on the upper side of the lottery result screen 730 may be different from the display form of the item displayed below the item. For example, for the item 1 and item 2 displayed on the upper side of the lottery result screen 730, both the image 731 and the name 732 are displayed, and for the item 3 displayed on the lower side, only the name 732 is displayed without displaying the image 731. Is displayed. This makes it possible to highlight and display items with a high degree of rarity or items with a small number of users.

  When the “use” button 733 is pressed, the item use screen 620 shown in FIG. 6C is displayed, and the radio button 625 of the item selected by lottery is automatically selected. Thereby, the player can use the item won by lottery immediately, and can improve the convenience of the player.

  The owned species are species that the player owns and has not yet been used. As garden information, for each region where a plant seed or plant is used (planted), the identification number of the region (region ID), the species ID of the species used or the plant identification number (plant ID) is stored in association with each other. The winning probability increase rate is stored in association with the identification number (lottery target item ID) for each lottery target item. The number of seeds provided is the number of seeds provided by the player to the friend player, and the number of seeds received is the number of seeds provided by the friend player to the player.

  FIG. 4B shows a seed table for managing plant seeds. In the species table, the species ID of the species, the name, the file name of the image data, the plant ID of the plant generated by growing the species (corresponding plant ID), the rarity of the species, and the like are stored in association with each other. Is done. The seed image data may be the same as the plant image data.

  FIG. 4C shows a plant table for managing plants. In the plant table, a plant ID, a name, a file name of image data, and the like of the plant are stored in association with each other.

  FIG. 4D shows a lottery target item table for managing lottery target items. In the lottery target item table, a lottery target item ID of the lottery target item, a name, a file name of image data, a winning probability, and the like are stored in association with each other.

  The progress control unit 331 controls the start and progress of the game, and appropriately instructs the setting unit 332, the winning probability changing unit 333, and the lottery unit 334 to execute the process. The progress control unit 331 exchanges necessary data with the mobile terminal 2 via the server communication unit 31.

  When the request for each screen described with reference to FIGS. 6A to 7C is received from the portable terminal 2, the progress control unit 331 specifies the player ID included in the request. Then, the progress control unit 331 creates display data for displaying a button for receiving an instruction from the player, character information notified to the player, an image, etc. in a layout corresponding to the screen, and the data is stored in the portable terminal. 2 to send. When any button is pressed on the screen displayed on the mobile terminal 2 in this way and a request for the next screen corresponding to the button is received from the mobile terminal 2, the progress control unit 331 similarly displays the next screen. Data is created and the data is transmitted to the mobile terminal 2.

  In particular, when the “acquire item” button 602 is pressed on the My Page screen 600 displayed on the mobile terminal 2 and a corresponding item acquisition request is received from the mobile terminal 2, the progress control unit 331 is included in the item acquisition request. The player ID is specified. The progress control unit 331 gives an item to the player by adding the ID of a predetermined item in association with the identified player ID in the player table. Then, the progress control unit 331 creates display data for redisplaying the my page screen 600 and transmits the data to the mobile terminal 2.

  In addition, when the “use item” button 603 is pressed on the My Page screen 600 displayed on the mobile terminal 2 and a corresponding item use screen request is received from the mobile terminal 2, the progress control unit 331 displays the item use screen request. The player ID included in is specified. The progress control unit 331 extracts the owned species ID and garden information corresponding to the specified player ID in the player table, and extracts each information corresponding to the extracted owned species ID and garden information in the seed table and the plant table. . The progress control unit 331 creates display data for displaying the item use screen 620 in which each extracted information is arranged in a predetermined layout, and transmits the data to the mobile terminal 2.

  Further, when the “place” button 626 is pressed on the item usage screen 620 displayed on the mobile terminal 2 and a corresponding item usage request is received from the mobile terminal 2, the progress control unit 331 is included in the item usage request. A player ID, a seed ID, and a region ID are specified. The progress control unit 331 deletes the owned species ID corresponding to the identified player ID in the player table, and adds the identified species ID and region ID in association with the garden information. Then, the progress control unit 331 creates display data for redisplaying the my page screen 600 and transmits the data to the mobile terminal 2.

  When the “present” button 627 is pressed on the item use screen 620 displayed on the mobile terminal 2 and a request corresponding to the button is received from the mobile terminal 2, the progress control unit 331 displays the player ID and the content included in the request. Species ID is specified. The progress control unit 331 deletes the identified seed ID from the owned seed ID of the identified player ID in the player table and adds it as the owned seed ID of the friend player. Thereby, the player can provide the seed of the plant which he owns to a friend player. Further, the progress control unit 331 increments (+1) the number of seeds provided by the player and the number of seeds received by the friend player. Then, the progress control unit 331 creates display data for redisplaying the my page screen 600 and transmits the data to the mobile terminal 2.

  When the “Growth” button 604 is pressed on the My Page screen 600 displayed on the mobile terminal 2 and a corresponding growth request is received from the mobile terminal 2, the progress control unit 331 determines the player ID included in the growth request. Is identified. The progress control unit 331 extracts all seed IDs from the garden information corresponding to the specified player ID in the player table. The progress control unit 331 determines, for each extracted seed ID, whether to grow the plant randomly using a predetermined random number seed or the like. The progress control unit 331 changes the plant seed to the plant by changing the species ID determined to grow on the plant to the corresponding plant ID in the garden information. In addition, the progress control unit 331 determines whether or not the changed species is a specific species whose rarity is equal to or greater than a predetermined value. When the changed seed is a specific seed, the progress control unit 331 gives an event point to each player by adding a predetermined value to the individual points and group points of the player and the group points of the friend player. Further, the progress control unit 331 updates the ranks of the player and the friend player according to the individual points or group points to which the predetermined value is added. Then, the progress control unit 331 creates display data for redisplaying the my page screen 600 and transmits the data to the mobile terminal 2.

  In addition, when the “Grow Friend Garden” button 605 is pressed on the My Page screen 600 displayed on the mobile terminal 2 and a corresponding request is received from the mobile terminal 2, the progress control unit 331 is included in the request. The player ID is specified. The progress control unit 331 extracts a friend player ID corresponding to the specified player ID in the player table, and extracts all seed IDs from the garden information corresponding to the extracted friend player ID. The progress control unit 331 changes the seed of the plant into a plant in the same manner as when the growth request is received. Moreover, when the changed seed is a specific seed, the progress control unit 331 gives an event point to each player by adding a predetermined value to the group point of the player and the group point of the friend player. Further, the progress control unit 331 updates the ranks of the player and the friend player according to the individual points or group points to which the predetermined value is added. Then, the progress control unit 331 creates display data for redisplaying the my page screen 600 and transmits the data to the mobile terminal 2.

  When the “setting” button 725 is pressed on the winning probability change screen 720 displayed on the mobile terminal 2 and a corresponding setting request is received from the mobile terminal 2, the progress control unit 331 performs processing on the setting unit 332. Instruct execution. Then, the progress control unit 331 creates display data for displaying the my page screen 600 and transmits the data to the mobile terminal 2.

  When the “lottery” button 606 is pressed on the My Page screen 600 displayed on the mobile terminal 2 and a corresponding lottery screen request is received from the mobile terminal 2, the progress control unit 331 sends a winning probability change unit 333 to the winning probability change unit 333. Instructs execution of winning probability calculation process. Then, the progress control unit 331 identifies the player ID included in the lottery screen request. The progress control unit 331 extracts a lotterable number of times, a rank of the player, and an event point corresponding to the specified player ID in the player table, and extracts each piece of information related to the lottery target item from the lottery target item table. The progress control unit 331 creates display data of a lottery screen 700 that displays each extracted information and the winning probabilities calculated by the winning probability changing unit 333 as a list, and transmits the display data to the portable terminal 2 of the player.

  When the “Lottery” button 710 is pressed on the lottery screen 700 displayed on the portable terminal 2 and a lottery request corresponding to the button is received from the portable terminal 2, the progress control unit 331 executes processing on the lottery unit 334. Instruct. And the progress control part 331 extracts each information regarding the lottery object item elected as a result of the lottery by the lottery part 334 from the lottery object item table. The progress control unit 331 creates display data of the lottery result screen 720 displaying a list of each extracted information, and transmits the display data to the portable terminal 2 of the player.

  When the setting request is given from the progress control unit 331, the setting unit 332 specifies the player ID included in the setting request, the lottery target item that increases the winning probability, and the rate of increase. The setting unit 332 changes the winning probability increase rate corresponding to the specified player ID in the player table, thereby selecting a lottery target item whose winning probability is changed based on the event point, and increasing the winning probability. That is, the setting unit 332 selects a lottery target item whose winning probability is changed according to a request from the player. The setting unit 332 may not only increase the winning probability of the lottery target item but also decrease it. For example, the setting unit 332 may decrease the increase rate of the winning probability of some lottery target items and increase the increase rate of the winning probability of other lottery target items by the decreased amount.

  The win probability changing unit 333 specifies the player ID included in the lottery screen request when the execution control unit 331 instructs execution of the win probability calculation process. The winning probability changing unit 333 extracts a rank and a winning probability increase rate corresponding to the specified player ID from the player table, and extracts a winning probability of each lottery target item from the lottery target item table.

  The winning probability changing unit 333 changes the winning probability of each extracted lottery target item based on the current rank of the player. The winning probability changing unit 333 changes the winning probability of each extracted lottery target item so that it becomes higher as the rank of the player is higher and lower as the rank is lower. For this purpose, the winning probability changing unit 333 calculates a changing ratio for changing the winning probability according to the rank of the player, and calculates a new winning probability by multiplying the winning probability of each lottery target item by the changing probability.

  For example, the change ratio of the lowest rank is set to 1, and the winning probability changing unit 333 calculates the change ratio of each rank so that the rank and the change ratio have a direct proportional relationship. Alternatively, the winning probability changing unit 333 may calculate the change ratio of each rank so that the change amount of the change ratio when the rank is increased by one monotonically decreases with respect to the increase of the rank. In this case, since the change ratio increases dramatically when the rank of the player is low, each player can increase the winning probability immediately after participating in the event, and can increase the number of players participating in the event. . Alternatively, the winning probability changing unit 333 may calculate the change ratio of each rank so that the change amount of the change ratio when the rank increases by one increases monotonously with respect to the increase in rank. In this case, since the change ratio increases dramatically as the rank increases, the number of times each player participates in the event can be improved.

  The winning probability changing unit 333 further changes the winning probability of each lottery target item based on the winning probability increasing rate set by the player.

  Similarly, the winning probability changing unit 333 calculates the winning probability at the next rank of the player for each lottery target item.

  In addition, the winning probability changing unit 333 may change the winning probability of each lottery target item based on the number of friend players stored in the player table. In that case, the winning probability changing unit 333 increases the winning probability as the number of friend players increases, and decreases the winning probability as the number of friend players decreases. Accordingly, each player can increase the number of friend players, and thus can activate communication in the game system 1.

  Further, the winning probability changing unit 333 may change the winning probability of each lottery target item based on the number of seeds provided or the number of seeds received stored in the player table. In that case, the winning probability changing unit 333 increases the winning probability as the number of seeds provided or received is higher, and lowers the winning probability as the number of seeds provided or received is lower. Thereby, since each player tries to increase seed exchanges with the friend player, it is possible to activate communication in the game system 1.

  The winning probability changing unit 333 may set at least one of the winning probabilities of each lottery target item to a probability equal to or higher than a predetermined value (for example, 99%). This reduces the possibility that the player will not be able to acquire any items, so that the player who performed the lottery can be prevented from feeling disappointed.

  The winning probability changing unit 333 may change the winning probabilities of at least some of the lottery target items and may not change the winning probabilities of all the lottery target items. For example, the winning probability changing unit 333 may change only the winning probability of the lottery target item having the highest rarity.

  When the lottery unit 334 receives a lottery request from the progress control unit 331, the lottery unit 334 specifies the player ID included in the lottery request. The lottery unit 334 extracts the number of possible lotteries corresponding to the specified player ID from the player table, and determines whether the number of possible lotteries is 1 or more. When the number of lottery is 0, the lottery unit 334 does not perform the lottery. On the other hand, when the number of lottery is 1 or more, the lottery unit 334 extracts all the lottery target items from the lottery target item table. Based on the winning probability changed by the winning probability changing unit 333, the lottery target items are lottery. That is, the lottery unit 334 performs lottery for all the lottery target items in accordance with one request from the player. In addition, the lottery unit 334 decrements (-1) the number of possible lotteries in the player table. Note that the number of possible lotteries is set to an upper limit value at a predetermined time (for example, 12:00).

  In addition, the lottery part 334 may perform the 2nd lottery which draws one item out of all the lottery object items, when the lottery object items are not lottery. Thereby, since the player can acquire at least one item, the player who performed the lottery can be prevented from feeling disappointed. Or the lottery part 334 may perform lottery again about some items (for example, item with the highest rarity degree) among all the lottery object items, when the lottery object items are not drawn. In this case, it is possible to give a sense of expectation to the player who once feels disappointment.

  The lottery unit 334 also draws one item out of all the lottery target items when a part of the lottery target items (for example, the item with the highest rarity) is won. May be performed. Thereby, when a specific item wins, a player can acquire an item further, the game nature of a lottery can improve, and a further expectation can be given to a player. Or, when a part (for example, an item having the highest rarity level) of all lottery target items is won, the lottery unit 334 may perform the lottery again. In this case as well, a further expectation can be given to the player.

  In addition, the lottery unit 334 may change the winning probability associated with other lottery target items based on the lottery results of some lottery target items among all the lottery target items. For example, the lottery unit 334 does not perform the lottery for all the lottery target items at the same time, but sequentially performs the lottery for each lottery target item one by one and causes the portable terminal 2 to display the lottery results one by one. When the lottery unit 334 wins a lottery for a specific lottery target item, the lottery unit 334 increases the winning probability of the remaining lottery target items that have not yet been lottery. Thereby, as each lottery wins, the winning probabilities of the remaining lottery target items increase, so that the game performance of the lottery increases and the player can have further expectation. Alternatively, the lottery unit 334 may increase the remaining winning probability that has not yet been drawn when the particular lottery item is not selected. Thereby, since possibility that a player cannot acquire an item at all will reduce, it can suppress that the player who performed the lottery feels disappointment.

  The granting unit 335 grants all the lottery target items won by the lottery performed by the lottery unit 334 to the player. The granting unit 335 stores all the lottery target item IDs won by the lottery by the lottery unit 334 in the player table as acquired premium IDs corresponding to the player IDs specified by the lottery unit 334.

  The granting unit 335 may further grant a privilege to the player when the lottery by the lottery unit 334 wins all the lottery target items. For example, the granting unit 335 increases the number of times that the player can be selected as a privilege in that case. Thereby, the game characteristic of a lottery improves and it can give a further expectation to a player. Alternatively, the granting unit 335 may grant a part of the selected lottery target item to the friend player of the player as a privilege in that case. Thereby, a friend player will thank a player and it becomes possible to activate communication between players.
