FIG. 2 shows a configuration example of the game system (server system) of the present embodiment. The configuration of the game system is not limited to FIG. 2, and various modifications such as omitting a part of the component (each part) or adding another component can be performed.

The game system includes a processing unit 100, an operation unit 160, a storage unit 170, a display unit 190, a sound output unit 192, an I / F unit 194, and a communication unit 196.

The processing unit 100 (processor) has lottery table processing, lottery processing, game processing, management processing, display processing, or sound based on various information, programs, operation information, etc. stored in the storage unit 170 (database). Perform processing etc.

Each process (each function) of the present embodiment performed by each unit of the processing unit 100 can be realized by a processor (a processor including hardware). For example, each process of the present embodiment can be realized by a processor that operates based on information such as a program and a memory that stores information such as a program. In the processor, for example, the functions of each part may be realized by individual hardware, or the functions of each part may be realized by integrated hardware. For example, a processor includes hardware, which hardware can include at least one of a circuit that processes a digital signal and a circuit that processes an analog signal. For example, the processor may be composed of one or more circuit devices (for example, ICs, etc.) mounted on a circuit board, or one or more circuit elements (for example, resistors, capacitors, etc.). The processor may be, for example, a CPU (Central Processing Unit). However, the processor is not limited to the CPU, and various processors such as a GPU (Graphics Processing Unit) or a DSP (Digital Signal Processor) can be used. Further, the processor may be a hardware circuit by ASIC. Further, the processor may include an amplifier circuit, a filter circuit, and the like for processing an analog signal. The memory (storage unit 170) may be a semiconductor memory such as SRAM or DRAM, or may be a register. Alternatively, it may be a magnetic storage device such as a hard disk device (HDD), or an optical storage device such as an optical disk device. For example, the memory stores instructions that can be read by a computer, and when the instructions are executed by the processor, the processing (function) of each part of the processing unit 100 is realized. The instruction here may be an instruction set that constitutes a program, or may be an instruction that instructs the hardware circuit of the processor to operate.

The processing unit 100 includes a lottery table processing unit 102, a lottery processing unit 108, a game processing unit 110, a management unit 112, a display processing unit 120, and a sound processing unit 130.

The lottery table processing unit 102 performs various processes on the lottery table. For example, a selection process for selecting a lottery table from a plurality of lottery tables is performed. For example, a process of selecting a lottery table from a plurality of lottery tables stored in the table storage unit 172 based on selection conditions is performed. Further, the lottery table processing unit 102 performs various change processing related to the lottery table. For example, the selection condition, the lottery condition, the transition condition, and the like of the lottery table are changed. For example, the lottery table processing unit 102 includes a table selection unit 104 and a change unit 106, the selection process is performed by the table selection unit 104, and the change process is performed by the change unit 106. Details of the lottery table processing will be described later.

The lottery processing unit 108 performs a lottery process for drawing a game medium to be given to the user. Specifically, the lottery processing unit 108 performs a lottery process of selecting a game medium from a plurality of game media and drawing a lot based on a given lottery instruction. For example, a lottery process is performed in which one of the game media (one or a plurality of game media) is selected from the plurality of game media.

The lottery instruction is, for example, a lottery instruction operated by the user. For example, when the user inputs the operation of the lottery instruction using the operation unit 160, the lottery processing unit 108 executes the lottery process. In this case, the user may be able to give a lottery instruction on the condition that the in-game currency is consumed, the ticket such as the Gasha ticket is consumed, or the game points are consumed. Alternatively, as in the case of free gasha, the user may be able to give a lottery instruction without requiring these consumptions. The in-game currency, gasha tickets, and game points are not limited to gasha, but may be obtained by a login bonus, game results, or payment of consideration for billing to the user. Further, the lottery instruction may be automatically issued by the system without relying on the user's operation. For example, in a game played by a user, when a quest or mission is completed by defeating an enemy or clearing a stage, a lottery instruction is automatically issued by the system, and the lottery processing unit 108 performs lottery processing. You may want to do it.

The game medium is a general term for electronic data used by a user in, for example, a game. For example, in a game played by a user, various game media such as electronic items, characters, avatars or cards are used. Items are weapons, armor, equipment, tools or parts in the game. Characters and avatars are mobiles that appear in the game. Electronic cards are, for example, character cards and item cards. The game medium is an electronic item, character, avatar, card, or the like, which is an element of gameplay. The game processing unit 110 uses this electronic game medium to execute game processing such as game progress processing. The game medium is acquired, used, owned, managed, exchanged, synthesized, strengthened, sold, deleted or donated according to the progress of the game, but the game medium of the present embodiment is limited to such usage. Not.

As described above, the game medium is a character or an item used in the game processing which is a game part. For example, it is possible to synthesize characters that are game media. In addition, items are used for strengthening and evolving a character, for recovering a character's physical strength, and for activating special effects in a game. An item is an item used to play a game. For example, it is an item that accumulates in-game currency required for gameplay, and an item that restores the user's stamina and energy required for gameplay. Alternatively, the item is an item for performing lottery play such as Gasha. For example, in-game currency accumulation items required for lottery play such as Gasha, tickets for lottery play such as Gasha tickets, lottery play becomes possible when a predetermined number is accumulated, or exchanged for items for lottery play Items that can be created or that can be arbitrarily selected as a character. Rarity is set for game media such as these characters and items. For example, in the case of characters and items, those with higher abilities and effects and those that can only be obtained for a limited time have higher rarity. Also, in the case of in-game currency and accumulated items of game points, the greater the amount of in-game currency and game points that can be obtained, the higher the rarity. In the case of tickets such as Gasha tickets, the easier it is to obtain a game medium with higher rarity, the higher the rarity.

The lottery process performed by the lottery processing unit 108 is performed using the lottery table. In the lottery table, lottery conditions for game media to be drawn are set. For example, as shown in FIG. 3A, in the lottery table TBL, lottery probabilities PMA, PMB, PMC ... Are set for each of the game media MA, MB, MC ... The lottery probability can also be said to be the winning probability or the emission probability. The lottery process is performed based on the lottery probabilities PMA, PMB, PMC ... In this case, the lottery probability may be changed when a predetermined change condition is satisfied. For example, the lottery probability of a game medium with high rarity is increased. Alternatively, the lottery probability of the game medium having low rarity may be lowered. As a result, the process of changing the lottery conditions is realized, and the probability that the game medium is drawn is changed.

Alternatively, the lottery probability is not set for each game medium as shown in FIG. 3 (A), but as shown in FIG. 3 (B), the game media MA, MB, MC ... In the lottery table TBL. On the other hand, the order of discharge 1, 2, 3, ... may be set, and the game media may be selected in this order. In this case, the lottery processing unit 108 performs the lottery process so that the order of the discharges is randomly determined. In this case, the discharge order may be changed when a predetermined change condition is satisfied. For example, change the order of the game media with high rarity to the front. Alternatively, the order of the game media having low rarity may be changed to the back. As a result, the process of changing the lottery conditions is realized, and the probability that the game medium is drawn is changed. In this way, the lottery conditions in the lottery table can be set (defined, defined) by the lottery probability of the game medium, the order of discharging the game medium, and the like.

The game processing unit 110 performs various game processing for the user to play the game. The game process calculates, for example, a process of starting a game when the game start condition is satisfied, a process of advancing the started game, a process of ending the game when the game end condition is satisfied, or a game result. Processing etc. The game processing unit 110 executes game processing based on game information such as game data and a game program stored in the game information storage unit 174. For example, the game processing unit 110 processes a game using a game medium set in a usable state. That is, the game is processed using the game medium acquired and owned by the user. The information of the game medium is stored in the game medium information storage unit 176.

Taking a browser game as an example, the game processing unit 110 controls the progress of the game for each user by managing the user information for each user. The user information is stored in the user information storage unit 178. For example, the game processing unit 110 causes the terminal device to display a web page constituting a website that provides a game service in response to a request from the terminal device. Specifically, a web page is displayed by a web browser provided in the terminal device. When the hyperlink of the displayed web page is selected by the user, the game processing unit 110 transmits new HTML data corresponding to the hyperlink to the terminal device, and the terminal device displays a web page based on the new HTML data. Is displayed. In this way, the game processing unit 110 sequentially provides the web pages to the terminal device according to the user's operation, so that the game can be advanced based on the user's operation on the terminal device.

For example, the table storage unit 172 stores a plurality of lottery tables in which lottery conditions for drawing a game medium to be given to the user are defined in each lottery table. The lottery conditions are conditions that are set (defined and defined) according to, for example, the lottery probability or the discharge order of the game medium as described above. The lottery condition can also be said to be a winning condition or a discharge condition of the game medium. For example, in each table of a plurality of lottery tables, the table storage unit 172 stores information on lottery parameters such as the lottery probability or the discharge order in association with the game medium to be drawn.

The lottery table processing unit 102 performs various processes on the lottery table. For example, the lottery table processing unit 102 performs a process of selecting a lottery table from a plurality of lottery tables. That is, the lottery table processing unit 102 performs a process of selecting a lottery table to be used for the lottery process from a plurality of lottery tables stored in the table storage unit 172 based on the selection conditions. This selection process is performed by the table selection unit 104. The selection condition can be set, for example, by the selection probability for selecting the lottery table to be used for the lottery process from a plurality of lottery tables. For example, the selection probability is associated with each lottery table of a plurality of lottery tables. Then, the lottery table processing unit 102 selects the lottery table to be used for the lottery process based on the selection condition set by the selection probability. Alternatively, the selection condition may be a condition set by, for example, the selection order of the lottery table. For example, a process of selecting a lottery table to be used for the lottery process may be performed in a predetermined selection order or a random selection order from a plurality of lottery tables. In this case, the selection conditions are set according to the selection order. It becomes a condition to be done.

The lottery processing unit 108 uses a lottery table selected from a plurality of lottery tables to perform a lottery process for drawing a game medium to be given to the user. For example, in the case of FIG. 3A, the lottery process is executed using the lottery probabilities PMA, PMB, PMC ... Corresponding to the game media MA, MB, MC ... Of the lottery table TBL. Determine the lottery medium to be given to the user. Further, in the case of FIG. 3B, the lottery process is executed and given to the user by using the discharge order 1, 2, 3 ... Corresponding to the game media MA, MB, MC ... Determine the lottery medium. For example, the lottery processing unit 108 performs lottery processing so that the order of discharge is randomly determined, and determines the lottery medium to be given to the user.

The display processing unit 120 performs display processing for the lottery process. For example, the display processing unit 120 displays an instruction screen for the user to give a lottery instruction, displays a lottery screen showing how the lottery is performed, or displays a lottery result screen for presenting the lottery result to the user. Perform processing etc. Further, the display processing unit 120 performs a process of displaying information for causing the user to recognize various information related to the lottery process. For example, as will be described later, when the selection condition, the transition condition, or the lottery condition is changed, the display processing unit 120 causes the user to recognize (identify) that these conditions have been changed. Performs processing to display symbols or effects.

Then, in the present embodiment, the lottery table processing unit 102 selects the current lottery table from the plurality of lottery tables. For example, the lottery table processing unit 102 selects a lottery table to be used for the current lottery process from a plurality of lottery tables stored in the table storage unit 172 based on the selection conditions. Then, the lottery processing unit 108 performs lottery processing using the selected lottery table of this time. That is, the lottery process for selecting the game medium to be given to the user is performed based on the lottery conditions set in the lottery table.

Then, the lottery table processing unit 102 determines whether or not to transition from the current lottery table to the transition destination lottery table (another lottery table) based on the transition condition. The transition condition can be set by the transition probability from the lottery table of the transition source to the lottery table of the transition destination. Alternatively, the transition condition may be set based on the probability of staying in the lottery table of the transition source. The stay probability can also be called the self-transition probability. Alternatively, the transition condition is based on a random element other than the transition probability or the stay probability, the user's game status, the game play status, the item status, the lottery status, the time information, the status information, etc., in addition to the transition probability or the stay probability. It may be set. Then, the lottery table processing unit 102 selects the next lottery table based on the determination result. The next lottery table is, for example, the current lottery table or the transition destination lottery table. The number of lottery tables at the transition destination is not limited to one, and may be plural. It is also possible to modify the lottery table so that it is not selected. For example, the lottery table processing unit 102 selects either the current lottery table or the transition destination lottery table as the next lottery table. For example, the lottery table processing unit 102 determines whether or not to transition from the current lottery table to the transition destination lottery table based on the transition condition, and if it is determined to make the transition, the transition destination lottery table is used for the next time. Select as a lottery table. On the other hand, when it is determined that the transition is not performed, the current lottery table, which is the transition source lottery table, is selected as the next lottery table. Then, the lottery processing unit 108 performs the lottery processing using the selected next lottery table. That is, in the next lottery process following the current lottery process, the lottery process is performed using the selected next lottery table.

Further, for example, it is assumed that an instruction for n consecutive lottery is given. Here, n is, for example, an integer of 2 or more. The instruction of the continuous lottery n times may be an instruction of the continuous lottery by the operation of the user, or the instruction of the continuous lottery may be automatically issued by the system without the operation of the user. When such an instruction for n consecutive lottery is given, in the first lottery process, the lottery table processing unit 102 selects the first lottery table from the plurality of lottery tables. .. For example, the lottery table processing unit 102 selects the first lottery table from a plurality of lottery tables based on the selection conditions. Then, the lottery processing unit 108 performs the first lottery processing using the selected lottery table for the first time. That is, the lottery process for determining the game medium to be given to the user is executed according to the lottery conditions set in the lottery table for the first time. It is not necessary to immediately give the game medium won by the lottery to the user, and for example, the game medium may be given after the end of n consecutive lottery.

Then, the lottery table processing unit 102 selects the lottery table for the second time based on the transition condition. The second lottery table is, for example, the first lottery table or the transition destination lottery table. For example, the lottery table processing unit 102 selects either the first lottery table or the transition destination lottery table as the second lottery table. That is, based on the transition condition, it is determined whether or not to transition from the first lottery table to the transition destination lottery table (another lottery table), and based on the judgment result, the first lottery table is used. One of the lottery tables of the transition destination is selected as the lottery table for the second time. For example, if it is determined that the lottery table will be transitioned, the lottery table of the transition destination will be selected as the second lottery table, and if it is determined that the lottery table will not be transitioned, the original lottery table for the first time will be selected. Select as the second lottery table.

On the other hand, in the i-th lottery process (i is an integer such that 2 ≦ i ≦ n), which is the second and subsequent lottery processes, the lottery processing unit 108 uses the lottery table for the i-th time selected last time. Is used to perform the i-th lottery process. Then, the lottery table processing unit 102 selects the lottery table for the i + 1th time based on the transition condition. The lottery table for the i + 1st time is, for example, the lottery table for the i-th time or the lottery table for the transition destination. For example, the lottery table processing unit 102 selects either the lottery table for the i-th time or the lottery table for the transition destination as the lottery table for the i + 1th time. That is, based on the transition condition, it is determined whether or not to transition from the i-th lottery table to the transition destination lottery table, and based on the judgment result, the i-th lottery table and the transition destination lottery table Select one of them as the lottery table for the i + 1th time. For example, if it is determined that the lottery table is to be transitioned, the lottery table of the transition destination is selected as the lottery table for the i + 1th time, and if it is determined that the lottery table is not to be changed, the original lottery table for the i-th time is selected. i + 1 Select as the lottery table for the first time. By repeating the above processing from the second lottery process to the nth lottery process, the continuous lottery process according to the instruction of the n consecutive lottery is executed.

Further, the lottery table processing unit 102 changes the selection condition when selecting the first lottery table from the plurality of lottery tables when the predetermined change condition is satisfied. For example, the lottery table processing unit 102 can determine whether or not the change condition is satisfied based on the game parameters used for the game processing. The game parameters are parameters for advancing the game, setting various situations about the game, or calculating the game results. For example, game parameters that set the status of the user or character include parameters such as offensive power, defensive power, endurance, hit points, magic points, or level. Specifically, the lottery table processing unit 102 determines whether or not a predetermined change condition is satisfied based on the user's game status, game play status, item status, lottery status, time information, status information, and the like. .. The user's game status includes the progress status of the user's game, the status of the user's game performance, the status of the game level, the status of the number of stage clears, the status of the game map and the environment, and the like. The game play status includes the status of the user's game operation, the status of the number and frequency of game play, the status of login to the game, and the like. The item status is the usage status and possession status of the item, the usage status of the item is the status such as whether or not the item has been used (consumed), and the possession status of the item is the possession status of the predetermined item. It is a situation such as whether or not. The lottery status is, for example, a situation such as a user's lottery result, for example, each lottery result within n consecutive lottery or a lottery result in a lottery process different from the n consecutive lottery. The time information is information such as a date, a time, or a period, for example, whether or not the current date, time, or period corresponds to a specific period such as a campaign period. The status information is status information about the ability, level, etc. of the user or the user character used by the user. Further, the status information may be the status information of another user or another user character used by another user. Then, when the lottery table processing unit 102 determines that the predetermined change condition associated with the selection condition is satisfied, the lottery table processing unit 102 changes the selection condition when selecting the lottery table for the first time. For example, the selection probability when selecting the first lottery table from a plurality of lottery tables is changed. For example, the selection probability, which is a selection condition, is changed so that a specific lottery table can be easily selected. Alternatively, when the lottery table is selected in a given selection order, the selection order which is the selection condition may be changed. Alternatively, the selection condition may be changed such that the first lottery table is selected from the lottery tables belonging to a specific group from the plurality of lottery tables.

Further, the display processing unit 120 performs a process of displaying information for making the user recognize that the selection condition has been changed. The information for making the user recognize that the selection condition has been changed is information such as an image, a character, a symbol, or an effect for making the user recognize the change in the selection condition, and for notifying the user of the change in the selection condition. Information. For example, when a predetermined change condition is satisfied and the selection condition for selecting the first lottery table from the plurality of lottery tables is changed, the display processing unit 120 changes the selection condition. A process of displaying an image, characters, symbols, effects, or the like for the user to recognize that is performed on the display unit 190. For example, display processing is performed to make the user recognize what kind of condition the changed selection condition is.

Further, the display processing unit 120 performs a process of displaying information for making the user recognize which lottery process is being performed out of the n lottery processes according to the instruction of the n consecutive lottery. For example, when an instruction for n consecutive lottery is given, each lottery is performed, such as the first lottery process, the second lottery process, the third lottery process, and so on. The processes are executed in sequence. In this case, the display processing unit 120 displays an image, a character, a symbol, an effect, or the like for the user to recognize which of the first to nth lottery processes is currently being performed. Performs the process of displaying in unit 190.

Further, the lottery table processing unit 102 changes the transition condition when the predetermined change condition is satisfied. That is, the lottery table processing unit 102 determines whether or not to transition from the current lottery table to the transition destination lottery table based on the transition condition, but the transition condition, which is the condition for transitioning the lottery table, is changed. Change when is satisfied. For example, the lottery table processing unit 102 can determine whether or not the change condition for the transition condition is satisfied based on the game parameter used for the game processing. Specifically, the lottery table processing unit 102 determines whether or not the change condition for the transition condition is satisfied based on the user's game status, game play status, item status, lottery status, time information, status information, and the like. to decide. For example, the transition condition is set by the transition probability from the lottery table of the transition source to the lottery table of the transition destination, the stay probability in the lottery table of the transition source, and the like, but the change condition is satisfied in the lottery table processing unit 102. If so, the transition conditions such as the transition probability or the stay probability are changed. Alternatively, the lottery table processing unit 102 may change the transition status (transition configuration) of a plurality of lottery tables when the change condition is satisfied. For example, when the change condition is satisfied, a lottery table of a new transition destination may appear and transition to the lottery table, or a lottery table that is not normally a transition destination may be transitioned.

Further, the display processing unit 120 performs a process of displaying information for making the user recognize that the transition condition has been changed. For example, when a predetermined change condition is satisfied and the transition condition for transitioning the lottery table is changed, the display processing unit 120 causes the user to recognize that the transition condition has been changed. Performs a process of displaying an effect or the like on the display unit 190. For example, display processing is performed to make the user recognize what kind of condition the transition condition after the change is. For example, when the change condition is satisfied and the transition probability from the transition source lottery table to the transition destination lottery table or the stay probability of staying at the transition source lottery table is changed, the display processing unit 120 sets the display processing unit 120. Performs a process of displaying an image, a character, a symbol, an effect, or the like for the user to recognize that the transition probability or the stay probability has been changed. Alternatively, when the change condition is satisfied and the transition status (transition configuration) of a plurality of lottery tables is changed, an image, characters, symbols, effects, etc. for making the user recognize the change of the transition status are displayed. Perform processing.

Further, the lottery table processing unit 102 performs a process of changing the lottery conditions of at least one lottery table of a plurality of lottery tables when a predetermined change condition is satisfied. That is, the lottery table processing unit 102 performs a lottery process of drawing a game medium to be given to the user based on the lottery conditions of the selected lottery table, but when the lottery conditions of the lottery table are changed. Change to. For example, the lottery table processing unit 102 can determine whether or not the change condition for the lottery condition is satisfied based on the game parameter used for the game processing. Specifically, the lottery table processing unit 102 determines whether or not the change conditions for the lottery conditions are satisfied based on the user's game status, game play status, item status, lottery status, time information, status information, and the like. to decide. For example, the lottery conditions are set according to the lottery probability or the discharge order of the game medium, but the lottery table processing unit 102 changes the lottery probability or the discharge order when the change conditions are satisfied. Alternatively, when the change condition is satisfied, the lottery table processing unit 102 changes the game medium to be drawn, the type of game medium, the group of game media to be drawn, the number of lottery, and the like. May be changed.

Further, the display processing unit 120 performs a process of displaying information for making the user recognize that the lottery conditions have been changed. For example, when a predetermined change condition is satisfied and the lottery condition of the lottery table used for the lottery process is changed, the display processing unit 120 causes the user to recognize that the lottery condition has been changed. A process of displaying characters, symbols, effects, etc. on the display unit 190 is performed. For example, a display process is performed to make the user recognize what kind of condition the changed lottery condition is. For example, when the change condition is satisfied and the lottery probability or the discharge order of the lottery table is changed, the display processing unit 120 causes the user to recognize that the lottery probability or the discharge order has been changed. Performs processing to display symbols or effects. Alternatively, when the change conditions are satisfied and the type of game medium or game medium to be drawn, the group of game media to be drawn, or the number of lottery is changed, the type of game medium or game medium, the lottery target Performs a process of displaying an image, a character, a symbol, an effect, or the like for the user to recognize the change in the group of game media or the number of lottery.

Further, the lottery table processing unit 102 performs a transition condition or at least one lottery table of a plurality of lottery tables when a predetermined change condition is satisfied when a continuous lottery is performed according to an instruction of n times of continuous lottery. Change the lottery conditions. For example, when the change condition for the transition condition is satisfied, the transition condition is changed, and when the change condition for the lottery condition is satisfied, the lottery condition of the lottery table is changed. Then, the lottery table processing unit 102 returns the changed transition condition or lottery condition to the initial state after the nth lottery process according to the instruction of the n consecutive lottery is completed. That is, the transition condition or the lottery condition is initialized. For example, when the change condition is satisfied in the continuous lottery and the transition condition or the lottery condition is changed, the transition condition or the lottery condition changes from the condition in the initial state. For example, when the transition probability or the stay probability, which is the transition condition, is changed, the transition probability or the stay probability changes from the transition probability or the stay probability in the initial state. In this case, when the nth lottery process according to the instruction of the n consecutive lottery is completed, the changed transition probability or stay probability is returned to the transition probability or stay probability in the initial state. Further, when the lottery probability or the discharge order, which is the lottery condition, is changed, the lottery probability or the discharge order changes from the lottery probability or the discharge order in the initial state. In this case, when the nth lottery process according to the instruction of the n consecutive lottery is completed, the changed lottery probability or the discharge order is returned to the initial state lottery probability or the discharge order.

Further, the lottery table processing unit 102 performs a process of excluding the game medium determined to be given to the user by the lottery process from the game media to be drawn in at least one lottery table of the plurality of lottery tables. .. For example, when one game medium from a plurality of game media is drawn as a lottery medium to be given to a user by a lottery process using a lottery table, the game medium is a plurality of games to be drawn for the lottery table. It is excluded from the medium and deleted. Then, after that, the game medium given to the user is drawn from among the plurality of game media from which the game medium has been deleted. When the lottery process is performed using the lottery tables selected from the plurality of lottery tables and the selected game medium is excluded from the selected lottery tables, the lottery table is included in the plurality of lottery tables. The lottery game medium may be excluded from the lottery table other than the lottery table.

Further, the display processing unit 120 performs a process of displaying information for making the user recognize the transition status of the plurality of lottery tables. For example, the display processing unit 120 performs a process of displaying an image, a character, a symbol, an effect, or the like for causing the user to recognize the transition status of a plurality of lottery tables on the display unit 190. The transition status of the plurality of lottery tables is the status of the transition configuration (connection configuration) of the plurality of lottery tables, the status of the transition probability between the lottery tables, the status of the stay probability of each lottery table, and the like. The display processing unit 120 is an image that allows the user to visually recognize the status of the transition configuration of the plurality of lottery tables, the status of the transition probability between the lottery tables, or the status of the stay probability of each lottery table. Display characters, symbols, effects, etc.

Further, the display processing unit 120 performs a process of displaying information for causing the user to recognize the current lottery table used for the lottery process. For example, the current lottery table is selected from a plurality of lottery tables, and the lottery process is performed using the selected current lottery table. The display processing unit 120 displays the current lottery table used for the lottery process. Is performed on the display unit 190 to display an image, characters, symbols, effects, or the like for causing the user to recognize. For example, information for making the user recognize which lottery table among the plurality of lottery tables is used and the lottery process is performed is displayed. Alternatively, the display processing unit 120 may perform a process of displaying information for causing the user to recognize the transition probability, the stay probability, and the like of the lottery table used.

Further, the display processing unit 120 performs a process of displaying information for making the user recognize that the game medium having a predetermined attribute is continuously assigned. For example, when a game medium having a predetermined attribute is continuously won by a continuous lottery or the like, the display processing unit 120 causes the user to recognize that the game medium having the predetermined attribute has been continuously won. Alternatively, a process of displaying an effect or the like on the display unit 190 is performed. The game medium having a predetermined attribute is, for example, a rare game medium such as SSR or SR, or a specific type of game medium representing a specific hero or heroine.

The game system and processing of the present embodiment of FIG. 2 described above may be realized by the server system 500 of FIG. 1A, realized by the terminal device TM, or distributed between the server system 500 and the terminal device TM. It is possible to carry out various modifications such as being realized by processing.

For example, when the present embodiment is realized by one program (application program), a lottery part and a game part may be provided in one program. The lottery part is a program module that executes lottery-related processing such as lottery processing, and is a gasha part that executes gasha-related processing. The game part is a program module that executes game-related processing such as game processing. The genre of the game in the game part does not matter. In this case, the game system of the present embodiment may be composed of a terminal device for executing the program and a server system, or may be composed of only a terminal device for executing the program without using the server system. It may be what is done.

Further, in this embodiment, the lottery part (Gasha part) and the game part may be separate programs. In this case, the information of the game medium acquired in the terminal device that executes the lottery part is transferred to the terminal device that executes the game part via the server system or a portable information storage medium such as a memory card. You may read and use it. Further, in this case, the game system of the present embodiment may be composed of a terminal device and a server system for executing the lottery part and the game part, respectively, or the terminal and the server system for executing the lottery part and the game part.

2. Method of this Embodiment Next, the method of this embodiment will be described in detail.

2.1 Transition of lottery table In the lottery process using the lottery table, the game medium is drawn based on the lottery conditions such as the lottery probability set by the lottery table and given to the user. However, as a parameter for adjusting the lottery process, there is only the lottery probability of the lottery table, and the lottery process that can respond to various requests cannot be realized. For example, for game media such as SSR (double super rare) and SR (super rare), the lottery probability is set to a low probability in the lottery table. Therefore, in a continuous lottery such as 10 consecutive Gasha, it is rare that the SSR or SR game medium is continuously won, and it is difficult to give the user an effective motivation for performing the continuous lottery. On the other hand, a method of increasing the lottery probability of winning the SSR or SR game medium alone is also conceivable so that the SSR or SR game medium is continuously won. However, this method is not desirable because the lottery probability of SSR or the like, which should be rarely won, becomes unnecessarily high.

Therefore, in the present embodiment, a plurality of lottery tables are prepared, the current lottery process is performed using the current lottery table, and then the transition from the current lottery table to the transition destination lottery table is performed based on the transition conditions. Judge whether or not to select the next lottery table. For example, in the case of transition, the lottery table of the transition destination is used as the next lottery table, and the next lottery process is performed. To. By performing the lottery process while sequentially transitioning the lottery table in this way, the lottery probability of the game medium for each rarity such as SSR and SR is not changed, and for example, the game medium in which SSR and SR are continuously won. It will be possible to realize the bias of the discharge contents and to realize the lottery process that can respond to various requests.

Next, the details of the method of the present embodiment will be described with reference to FIG. FIG. 4 is an example of a lottery table and its transition configuration used in the method of the present embodiment. In FIG. 4, lottery tables TA, TB, and TC are prepared as a plurality of lottery tables. Transition conditions to other lottery tables are set in each of these lottery tables TA, TB, and TC. For example, the lottery table TA is transitioned to TB with a transition probability of Q (A, B) = 0.492. In other words, the probability of staying in TA without transitioning from the lottery table TA is Q (A, A) = 1-Q (A, B) = 0.508. Further, the lottery table TB to TC has a transition probability of Q (B, C) = 0.31, and the lottery table TC to TB has a transition probability of Q (C, B) = 0.1903. Further, the lottery table TB is transitioned to TA with a transition probability of Q (B, A) = 0.04. The probability of staying in TB without transitioning from the lottery table TB is Q (B, B) = 1-Q (B, C) -Q (B, A) = 0.65, and the transition from the lottery table TC. The probability of staying at TC without doing so is Q (C, C) = 1-Q (C, B) = 0.8097. The selection probabilities that the TA, TB, and TC lottery tables are selected from the plurality of lottery tables are P (A) = 0.03, P (B) = 0.36896, and P (C) =, respectively. It becomes 0.60104.

When the lottery table TA is selected, the lottery probability of the SSR is 1.0, and when the TA is selected, the SSR is won with a 100% probability. Therefore, the selection probability of the lottery table TA is the lowest, such as P (A) = 0.03. When the lottery table TB is selected, the lottery probabilities of SR and R are 0.4 and 0.6, respectively, and when TB is selected, SR is won with a probability of 40%. Therefore, the selection probability of the lottery table TB is higher than the selection probability P (A) of the lottery table TA, such as P (B) = 0.36896, but lower than the selection probability P (C) of the lottery table TC. ing. When the lottery table TC is selected, the lottery probabilities of SR and R are 0.0373 and 0.9627, respectively, and in most cases, R is drawn. Therefore, the selection probability of the lottery table TC is the highest, such as P (C) = 0.60104.

When the state transition of FIG. 4 is used, the probability that the SSR is discharged is P (A) × 1.0 = 0.03. The probability that SR is discharged is P (B) × 0.4 + P (C) × 0.0373 = 0.36896 × 0.4 + 0.60104 × 0.0373 = 0.17. The probability that R is discharged is P (B) × 0.6 + P (C) × 0.9627 = 0.36896 × 0.6 + 0.60104 × 0.9627 = 0.8. That is, SSR is discharged with a probability of 3%, SR is discharged with a probability of 17%, and R is discharged with a probability of 80%.

The state transition in FIG. 4 is a stochastic process in which the next selection probability of the lottery table has Markov property obtained only from the current (current) selection probability. For example, a method called the Markov chain Monte Carlo method has been conventionally known. Here, the Markov process refers to a stochastic process having Markov property, and is a stochastic process in which the state transition depends only on the current state. A stochastic process is a random variable that changes over time. A Markov chain is a Markov process, which is a kind of stochastic process, in which the possible states are discrete. On the other hand, a method called the Monte Carlo method is known as a calculation method for obtaining a desired value by using sampling. The Monte Carlo method using Markov chains for sampling the probability space is called the Markov chain Monte Carlo method (hereinafter, appropriately referred to as MCMC method).

For example, the selection probabilities of the lottery tables TA, TB, and TC in the state transition of FIG. 4 can be expressed using a matrix as shown in the following equation (1).

In the above equation (1), the next selection probabilities P (A, i + 1), P (B, i + 1), P (C, i + 1) are the current selection probabilities P (A, i), P (B, i). , P (C, i), and can be obtained by using the matrix on the right side of the above equation (1) (hereinafter referred to as matrix M), which is a stochastic process having Markov property. Each element of the matrix M has stay probabilities Q (A, A), Q (B, B), Q (C, C), transition probabilities Q (A, B), Q (B, A), Q in FIG. It is set by (B, C) and Q (C, B).

For example, the selection probability of the lottery table TA can be expressed as P (A, i + 1) = 0.508 × P (A, i) + 0.04 × P (B, i). That is, the next selection probability P (A, i + 1) of the lottery table TA is obtained by multiplying the current selection probability P (A, i) of the lottery table TA by the stay probability Q (A, A) = 0.508 of TA. It is expressed as the sum of the result and the current selection probability P (B, i) of the lottery table TB multiplied by the transition probability Q (B, A) = 0.04 from the lottery table TB to TA. Can be done.

The selection probability of the lottery table TB can be expressed as P (B, i + 1) = 0.492 × P (A, i) +0.65 × P (B, i) +0.1903 × P (C, i). can. That is, the next selection probability P (B, i + 1) is obtained by multiplying the current selection probability P (A, i) of TA by the transition probability Q (A, B) = 0.492 from TA to TB. , TB's current selection probability P (B, i) multiplied by TB's stay probability Q (B, B) = 0.65, and TC's current selection probability P (C, i) Therefore, it can be expressed as the sum of the transition probability from TC to TB multiplied by Q (C, B) = 0.1903.

The selection probability of the lottery table TC can be expressed as P (C, i + 1) = 0.31 × P (B, i) + 0.8097 × P (C, i). That is, the next selection probability P (C, i + 1) is obtained by multiplying the current selection probability P (B, i) of TB by the transition probability Q (B, C) = 0.31 from TB to TC. , TC's current selection probability P (C, i) can be expressed as the sum of TC's stay probability Q (C, C) = 0.8097.

Thus, in the state transition of FIG. 4, the next selection probabilities P (A, i + 1), P (B, i + 1), P (C, i + 1) of the lottery tables TA, TB, TC are the current selection probabilities P ( It is a stochastic process that can be obtained only from A, i), P (B, i), and P (C, i), and is a stochastic process with Markov property.

Considering the case where the state transition in FIG. 4 has a stationary distribution, the following equation (2) holds. The steady distribution is the probability that each state will be reached when the state transitions occur infinitely. In the steady state, P (A, i + 1) = P (A, i) = P (A), P (B, i + 1) = P (B, i) = P (B), P (C, i + 1) = P It can be considered that (C, i) = P (C).

Further, the following equation (3) holds for the selection probabilities P (A), P (B), and P (C).

By solving the above equations (2) and (3) by linear algebra, the selection probabilities P (A), P (B), and P (C) of the lottery tables TA, TB, and TC shown in FIG. It can be obtained as in 4).

That is, in the steady distribution in which the state transitions in FIG. 4 have changed infinitely, the selection probabilities of the lottery tables TA, TB, and TC are P (A) = 0.03, P (B) = 0.36896, P (C) =. It can be considered that it converges to 0.60104. In this way, by setting the state transitions of the lottery tables TA, TB, and TC to the state transitions as shown in FIG. 4, the selection probabilities of the lottery tables TA, TB, and TC are set to P (A) = 0.03, P. (B) = 0.36896 and P (C) = 0.60104 can be set. For example, the selection probability of the lottery table TA for determining the SSR in which the SSR is discharged with a probability of 100% can be sufficiently reduced as P (A) = 0.03. Further, the selection probability of the lottery table TB in which SR is discharged with a probability of 40% is P (B) = 0.36896, and the selection probability P (C) = 0. It can be smaller than 60104.

For example, substituting (P (A, i), P (B, i), P (C, i)) = (1,0,0) into the above equation (1), as shown in the following equation (5). In addition, the selection probabilities of the lottery tables TA, TB, and TC are (P (A, i + 1), P (B, i + 1), P (C, i + 1)) = (0.508, 0.492, 0). I want to.

That is, when the currently selected lottery table is TA, the lottery table TA is selected with a high probability of 50.8% even in the next time. That is, the selection probability of the lottery table TA in the stationary distribution is very low, such as P (A) = 0.03, but once the lottery table TA is selected, there is a high probability that the lottery table TA will be selected next time. Is selected and the lottery process is performed.

Substituting (P (A, i), P (B, i), P (C, i)) = (0,1,0) into the above equation (1), as shown in the following equation (6). In addition, the selection probabilities of the lottery tables TA, TB, and TC are (P (A, i + 1), P (B, i + 1), P (C, i + 1)) = (0.04,0.65,0.31). It can be found like this.

That is, when the currently selected lottery table is TB, the lottery table TB is selected with a high probability of 65% and the lottery process is performed even in the next time. On the other hand, the probability of the transition to be promoted to the lottery table TA for SSR is as low as 4%, and the transition to be demoted to the lottery table TC is performed with a probability of 31%.

For example, in a general MCMC method, as described in FIGS. 9 and 10 described later, a random variable is sampled after the state transition is repeated many times. On the other hand, in the present embodiment, for example, in FIG. 4, after the lottery table TA for SSR is selected with the selection probability P (A) = 0.03, the stay probability is Q (A, A) = 0.508. The lottery table TA is selected with. The stay probability can also be called the self-transition probability. For example, unlike the MCMC method, the state transition is repeated many times and then sampling is not performed, but when the lottery table is selected, for example, only one state transition is performed. As a result, once the lottery table TA is selected and the SSR is discharged, the SSR will be discharged with a probability of 50.8% in the next time as well. Therefore, even if the SSR has an extremely low lottery probability, once it is discharged, it will be continuously discharged with a high probability. In the above, it has been explained that only one state transition is performed when selecting the lottery table, but the state transition is performed a small number of times (for example, 10 times or less) that cannot be regarded as returning to the steady state. May be good. That is, the state transition may be performed a plurality of times when the lottery table is selected based on the transition condition. For example, the process of rolling the hexahedral dice may be performed, and the state transition may be performed as many times as the number of rolls.

For example, in the lottery process using the lottery table so far, it is extremely rare that a game medium having a low emission probability such as SSR is continuously won, so it is an effective motivation to give a continuous lottery instruction. It was difficult to give to the user. On the other hand, in the present embodiment, even in a game medium having a low emission probability such as SSR, the probability of winning continuously increases, and the user is given an effective motivation to give continuous lottery instructions. be able to. Moreover, according to the present embodiment, the high rarity game media having a low emission probability are collectively discharged while keeping the average emission probability of each game medium as it is. That is, as described above, according to the state transition of FIG. 4, in the steady state, the emission probabilities of SSR, SR, and R are 0.03, 0.17, and 0.8, respectively, with a probability of 3%. SSR is discharged, SR is discharged with a probability of 17%, and R is discharged with a probability of 80%. Therefore, the average emission probabilities of SSR, SR, and R are maintained at the emission probabilities according to their respective rarities. However, once the SSR is won and discharged, the SSR will be won and discharged with a high probability in the next time as well. For example, in FIG. 4, by making the probability of staying in the lottery table TA sufficiently higher than the probability of staying in the lottery table TA (A, A) as compared with the probability of selecting P (A) of the lottery table TA, it is easy to continuously win SSRs having an extremely low emission probability. It is possible to do. Similarly, once the SR is won and discharged, the SR will be won and discharged with a high probability in the next time as well. For example, in FIG. 4, by increasing the probability of staying in the lottery table TB Q (B, B) as compared with the selection probability P (B) of the lottery table TB, it is possible to facilitate continuous winning of SRs with a low emission probability. It will be possible. As described above, according to the present embodiment, it is possible to increase the probability of continuous winning of a highly rare game medium while maintaining the average emission probability of SSR, SR, and R, and to give continuous lottery instructions. Effective motivation for things can be given to the user.

Next, the processing of this embodiment will be described in detail. FIG. 5 is a flowchart illustrating the processing of the present embodiment. First, the game system (server system, lottery table processing unit, processor) selects the current lottery table from a plurality of lottery tables based on the selection conditions (step S1). Taking FIG. 4 as an example, the selection probabilities, which are the selection conditions for the lottery tables TA, TB, and TC, are P (A) = 0.03, P (B) = 0.36896, and P (C) = 0, respectively. It is set to .60104. Therefore, the lottery tables TA, TB, and TC are selected with the selection probabilities of P (A) = 0.03, P (B) = 0.36896, and P (C) = 0.60104. This selection process can be performed by using the MCMC method described with reference to FIGS. 9 and 10 described later. For example, the lottery table selection process is realized by repeating the state transition of FIG. 4 many times.

Next, the game system (server system, lottery processing unit, processor) executes the lottery process using the selected lottery table (step S2). For example, when the lottery table TA is selected in step S1, the lottery process in which the SSR is discharged is executed with a 100% probability. When the lottery table TB is selected, the lottery process in which SR is discharged with a probability of 40% is executed, and when the lottery table TC is selected, SR is discharged with a probability of 3.73%. The lottery process is executed. Note that the game medium won by the lottery process may not be given to the user immediately, but may be given after a series of lottery processes are completed.

Next, the game system (server system, lottery table processing unit, processor) determines whether or not to transition from the current lottery table to the transition destination lottery table based on the transition conditions (step S3). For example, when the lottery table TA is selected, this time based on the transition conditions set by the transition probability Q (A, B) = 0.492, the stay probability Q (A, A) = 0.508, and the like. It is determined whether or not to transition from TA, which is the lottery table, to TB, which is the lottery table of the transition destination. When the lottery table TB is selected, the transition probability Q (B, A) = 0.04, Q (B, C) = 0.31, the stay probability Q (B, B) = 0.65, etc. Based on the transition condition to be set, it is determined whether or not to transition from TB, which is the current lottery table, to TA or TC, which is the transition destination lottery table. When the lottery table TC is selected, this time based on the transition conditions set by the transition probability Q (C, B) = 0.1903, the stay probability Q (C, C) = 0.8097, and the like. It is determined whether or not to transition from TC, which is a lottery table, to TB, which is a lottery table of the transition destination.

Next, the game system (server system, lottery table processing unit, processor) selects the next lottery table based on the determination result in step S3 (step S4). For example, either the current lottery table or the transition destination lottery table is selected as the next lottery table. For example, when it is determined in step S3 that the lottery table is to be transitioned when the lottery table this time is TA, the lottery table TB of the transition destination is selected as the next lottery table, and it is determined that the lottery table is not to be transitioned. , Select this lottery table TA as the next lottery table. When it is determined in step S3 that the lottery table is to be transitioned when the lottery table is TB, the lottery table TA or TC of the transition destination is selected as the next lottery table, and if it is determined not to be transitioned, The current lottery table TB is selected as the next lottery table. If it is determined in step S3 that the lottery table will be transitioned when the current lottery table is TC, the lottery table TB of the transition destination will be selected as the next lottery table, and if it is determined that the lottery table will not be transitioned, The current lottery table TC is selected as the next lottery table.

When either the current lottery table or the transition destination lottery table is selected as the next lottery table in step S4, FIGS. 7 (A) to 7 (C) and 8 (A) described later will be described. -As shown in FIG. 8C, the number of lottery tables at the transition destination may be plural. For example, in FIG. 7A, the number of lottery tables to which the lottery table TA is transitioned is two, such as TB and TC. In FIG. 8C, the number of lottery tables to which the lottery table TE is transitioned is four, such as TA, TB, TC, and TD. Further, the current lottery table may be excluded as a selection candidate for the next lottery table in step S4. For example, in FIGS. 7 (A) to 7 (C), the stay probabilities Q (A, A), Q (B, B), Q (C, C) or Q (D) of the lottery tables TA, TB, TC, TD. , D) may be set to 0. Further, in FIG. 8D, the transition to the next lottery table is always performed without staying at the lottery table this time.

Next, the game system (server system, lottery processing unit, processor) executes the lottery process using the selected next lottery table (step S5). For example, when the current lottery table is TA and the next lottery table is also TA, the lottery using the SSR-confirmed lottery table TA will be continuously executed. Further, when the lottery table this time is TB and the next lottery table is also TB, the lottery using the lottery table TB in which SR is discharged with a probability of 40% will be continuously executed. ..

As described above, in the present embodiment, the current lottery table is selected from the plurality of lottery tables, and the lottery process is performed using the selected current lottery table. Further, it is determined whether or not to transition the lottery table, the next lottery table is selected based on the determination result, and the lottery process is performed using the selected next lottery table.

For example, in the lottery process using the lottery table so far, the lottery adjustment parameter is only the lottery probability of the lottery table, and it is difficult to realize the lottery process that can respond to various requests. On the other hand, according to the method of the present embodiment, it is determined whether or not to transition the lottery table based on the transition condition, the next lottery table is selected based on the determination result, and the lottery process is executed. Therefore, as the adjustment parameter of the lottery, it is possible to use the parameter of the transition condition in addition to the parameter of the lottery condition. As a result, it becomes possible to facilitate continuous discharge of a specific game medium such as a game medium having a high rarity, and it becomes possible to realize a lottery process capable of responding to various requests. Therefore, it becomes possible to realize a process that could not be realized by the conventional lottery process using the lottery table.

In FIG. 4, the selection probabilities of the lottery tables TA, TB, and TC have a relationship of P (A) <P (B) <P (C). For example, the selection probability is set to be lower as the lottery table discharges a game medium having a higher rarity. This makes it possible to set the selection probability according to the rarity of the game medium. Further, in the lottery table TA that discharges the SSR, the stay probability Q (A, A) is sufficiently larger than the selection probability P (A). This makes it possible to realize a lottery table and its transition that facilitates continuous winning of highly rare game media. Further, the transition probability Q (B, A) of the transition from the lottery table TB to TA is smaller than the transition probability Q (A, B) of the transition from the lottery table TA to TB. As a result, it is possible to realize a transition of the lottery table in which the probability of the transition to be promoted is lower than the probability of the transition to be demoted. The promotion transition is, for example, a transition to a lottery table in which the probability of acquiring a highly rare game medium is high, and the demotion transition is, for example, a transition in which the probability of acquiring a highly rare game medium is low. It is a transition to the lottery table.

FIG. 6 is a flowchart illustrating a detailed processing example of the present embodiment. FIG. 6 is a processing example when the method of the present embodiment is applied to a continuous gasha such as a 10-series gasha.

First, the game system determines whether or not the user has instructed the continuous lottery n times (step S11). For example, in the case of 10 consecutive Gasha, n = 10, and in the case of 11 consecutive Gasha, n = 11. In addition, the continuous lottery instruction may be automatically given by the achievement of the quest or the mission without the operation of the user. Then, when the instruction of the continuous lottery is given n times, the game system selects the first lottery table from the plurality of lottery tables based on the selection condition (step S12). Taking FIG. 4 as an example, selection from the lottery tables TA, TB, and TC based on the selection probability of P (A) = 0.03, P (B) = 0.36896, and P (C) = 0.60104. The first lottery table is selected based on the conditions. The lottery table selection process may be realized by repeating the state transition many times by the MCMC method.

Next, the game system executes the first lottery process using the first lottery table (step S13). For example, when the lottery table TA of FIG. 4 is selected for the first time, the lottery process is executed under the lottery condition that the lottery probability of SSR is 100%. When the lottery table TB is selected for the first time, the lottery process in which the SR lottery probability is 40% and the R lottery probability is 60% is executed. When the lottery table TC is selected for the first time, the lottery process is executed in which the SR lottery probability is 3.73% and the R lottery probability is 96.27%.

Next, the game system selects the second lottery table based on the transition condition (step S14). For example, when the lottery table TA of FIG. 4 is selected for the first time, the transition condition is that the lottery table TA is transitioned to the lottery table TB with a probability of 49.2% and stays at the lottery table TA with a probability of 50.8%. Based on this, either the lottery table TA or TB is selected as the second lottery table. When the lottery table TB is selected for the first time, there is a 4% and 31% probability of transitioning to the lottery table TA and TC, and a 65% probability of staying at the lottery table TB. Based on this, any of the lottery tables TA, TB, and TC is selected as the second lottery table. When the lottery table TC is selected for the second time, the lottery is based on the transition condition that the lottery table TC is transitioned to the lottery table TB with a probability of 19.03% and stays at the lottery table TC with a probability of 80.97%. Either the table TB or TC is selected as the second lottery table.

Next, i = 2 is set, and the game system executes the i-th lottery process using the i-th lottery table selected last time (steps S15 and S16). That is, the second lottery process is executed using the second lottery table selected last time. Then, based on the transition condition, the lottery table for the i + 1th time is selected (step S17). For example, based on the transition conditions set in the transition probability, the stay probability, etc. shown in FIG. 4, either the second lottery table or the transition destination lottery table of the second lottery table is used. , Selected as the third lottery table used for the third lottery process. Then, it is determined whether or not i = n has been reached, and if i = n has not been reached, i = i + 1 and the process returns to step S16 (steps S18 and S19). Then, the third lottery process is executed using the third lottery table selected last time, and either the third lottery table or the transition destination lottery table is the fourth time. Selected as a lottery table for. In this way, the processes of steps S16 to S19 are repeated until i = n is reached, and when i = n is reached, the process ends.

As described above, according to the detailed processing example of FIG. 6, when the instruction of the continuous lottery n times is given, the lottery table for the first time is selected and the lottery process for the first time is performed. While the lottery table is transitioned according to the transition conditions, the second to nth lottery processes using the second to nth lottery tables are executed. As a result, it becomes possible to execute a continuous lottery process such as 10 consecutive gashas while changing the lottery table used for the lottery process. Then, in the continuous lottery process, it becomes possible to facilitate continuous discharge of a specific game medium such as a game medium having a high rarity, and it becomes possible to realize a continuous lottery process capable of responding to various requests. ..

It should be noted that various modifications can be performed as the processing of the present embodiment. For example, the order of the transition process of the lottery table and the lottery process is arbitrary, and the transfer destination of the lottery table may be determined after the game medium to be given to the user is determined. For example, after the lottery table is changed, the game medium may be given by the lottery process, or the game medium may be given by the lottery process, and then the lottery table may be changed. Further, the game medium determined to be given to the user by the lottery does not need to be given at the timing of each lottery process of the continuous lottery process. For example, the game medium is given to the user at the timing when all the continuous lottery processes are completed. You may. For example, when a specific game medium such as SSR is won, the specific content of the game medium is not presented to the user at the timing of each lottery process, and the specific content is presented after the continuous lottery process is completed. You may try to do it. Further, the continuous lottery process does not necessarily have to be performed continuously in time, and one lottery process and the next lottery process may be separated in time. For example, the current lottery process may be executed after login, and the next lottery process may be executed after the first login after the date changes. It is also possible to execute a lottery process such as a continuous lottery process using the probability distribution of the game medium acquired and developed based on the lottery table transition process without executing the lottery table transition process in real time. Is. Further, the same one lottery table in which the lottery conditions such as the lottery probability are changed may be regarded as a plurality of lottery tables.

Further, various modifications can be made to the plurality of lottery tables and their transition modes. 7 (A) to 7 (C) and 8 (A) to 8 (D) are explanatory views of various transition configuration examples of the lottery table.

For example, as shown in FIG. 7A, there may be a route for transitioning from the lottery table TA to TC. In FIG. 7 (A), for example, there is a transition route in which the lottery table TA is demoted to TC with a low transition probability Q (A, C). Alternatively, as shown in FIG. 7B, there may be a route for transitioning from the lottery table TC to TA. In FIG. 7B, for example, there is a transition path in which the lottery table TC is promoted to TA with a low transition probability Q (C, A). Further, the number of lottery tables is not limited to three as shown in FIG. 4, and may be four or more, or can be modified to two. For example, in FIG. 7C, a lottery table TD is provided in addition to the lottery tables TA, TB, and TC. Then, the transition between the lottery tables TC and TD is made under the transition conditions of the transition probabilities Q (C, D) and Q (D, C), and the transition probabilities Q (B, D) and Q are between the lottery tables TB and TD. The transition is made under the transition conditions (D, B). In FIG. 7C, a fifth lottery table TE (not shown) may be further provided.

Further, the transition route between the lottery tables is not limited to the transition route as shown in FIG. 4, and various modifications such as providing a plurality of transition routes can be performed. For example, in FIG. 8A, a transition route via the lottery table TB'is provided between the lottery tables TA and TC in addition to the transition route via the lottery table TB. The lottery table TB'is, for example, a table derived from the lottery table TB, and the lottery conditions such as the lottery probability are the same or similar settings. Then, for example, the lottery tables TB and TB'are different in the type of game medium to be discharged and the degree of rarity. Alternatively, conversely, the lottery conditions may be different by setting the type of the game medium to be discharged and the degree of rarity to be the same or similar in the lottery tables TB and TB'. In FIG. 8B, in addition to the transition route between the lottery tables TB and TC, a transition route between the lottery tables TB and TC'is provided. The lottery table TC'is also a derivative table of the lottery table TC.

In FIG. 8C, a lottery table TA in which the game medium of the hero is discharged, a lottery table TD in which the game medium of the heroine is discharged, and a lottery table TE in which the game medium of the pet is discharged are provided. The game media of these heroes, heroines, and pets have become, for example, high rarity game media. For example, the selection probability of the lottery tables TA, TD, and TE is lower than that of the other lottery tables TB and TC. On the other hand, the stay probabilities of the lottery tables TA, TD, and TE are higher than the selection probabilities of each. As a result, once the lottery tables TA, TD, and TE are selected, the probability of staying at the lottery table will increase again, and the transition conditions will make it easier for the game media of the hero, heroine, or pet to be continuously won. It is set. For example, when the user aims to collect the game medium of the hero, the lottery table TA can be easily selected by using a specific item, for example, and the game medium of the hero being collected is continuous. You will aim for acquisition. On the other hand, when the user aims to collect the heroine or pet game medium, the heroine is being collected so that the lottery table TD or TE can be easily selected by using, for example, a specific item. Alternatively, the aim is to continuously acquire pet game media.

Further, in FIG. 8D, ten lottery tables TA, TB, TC ... TJ are connected in a ring shape. Then, the lottery table TA to TB, TB to TC, TC to TD ... TI to TJ, TJ to TA transition probabilities Q (A, B), Q (B, C), Q (C, D) ... Q (I, J) and Q (J, A) are set to 1.0, and the next lottery table is transitioned with a 100% transition probability. That is, the stay probability is set to 0%. For the lottery tables TA to TI, the lottery probability of SSR is set to 0.0, but the lottery probability of SSR is set to 0.3 in the lottery table TJ, and the probability of 30% in the lottery table TJ. SSR is discharged at. In the first round of 10 consecutive Gasha, one lottery table is selected from the lottery tables TA to TJ. The selection probability of each lottery table of TA to TJ is set to 0.1. By using the lottery tables TA to TJ having a transition configuration as shown in FIG. 8 (D), it is possible to realize a lottery process in which SSR is discharged with a probability of 3% in 10 consecutive Gasha. For example, in FIG. 8D, the probability that the SSR does not hit at all can be set to 70% in the 10-series Gasha, although the SSR does not hit a plurality of times. For example, in 10 consecutive Gasha, if the lottery process in which the SSR lottery probability is 3% is repeated 10 times, the probability that the SSR will not be won at all becomes (1-0.3) ¹⁰ = 0.97 ¹⁰ = 0.737. Since it is 73.7%, the probability that the SSR will not hit at all cannot be set to 70%. On the other hand, in FIG. 8 (D), the SSR does not hit multiple times, but instead, the probability that the SSR does not hit at all in 10 consecutive Gasha can be set to 70%, which is 3.7%. It becomes possible to hedge the risk by the amount of.

Further, as described above, the first selection process of the lottery table may be realized by the MCMC method. For example, FIGS. 9 and 10 are explanatory views of the MCMC method.

In FIG. 9, the selection probabilities P (A, 1), P (B, 1), and P (C, 1) of the first (first station) lottery table TA, TB, and TC where i = 1 are obtained, respectively. , 33%, 33%, 34%. In this case, the emission probability of SSR is 33% × 1.0 = 33%, and the emission probability of SR is 33% × 0.4 + 34% × 0.0373 = 14.468%. The emission probability of R is 33% × 0.6 + 34% × 0.9627 = 52.532%.

The second (second) selection probabilities P (A, 2), P (B, 2), and P (C, 2) at which i = 2 are initial vectors (P (A, 1), It is obtained by multiplying P (B, 1), P (C, 1)) by the matrix M of the above equation (1). For example, in FIG. 9, P (A, 2), P (B, 2), and P (C, 2) are 18.084%, 44.156%, and 37.760%, respectively, and their selection probabilities. The emission probabilities of SSR, SR, and R based on the above are 18.084%, 19.071%, and 62.845%, respectively. Next, the third selection probabilities P (A, 3), P (B, 3), and P (C, 3) at which i = 3 are (P (A, 2), P (B, 2), P. It is obtained by multiplying (C, 2)) by the matrix M. For example, in FIG. 9, P (A, 3), P (B, 3), and P (C, 3) are 10.953%, 44.785%, and 44.263%, respectively, and their selection probabilities. The emission probabilities of SSR, SR, and R based on the above are 10.953%, 19.565%, and 69.482%, respectively.

In this way, in the MCMC method, the operation of multiplying the matrix M in an infinite loop is repeated. Then, it is determined whether or not it has converged to the steady state. For example, the number of times i = icv in which the emission probability of the game medium falls within an error of 0.0005% for all n stations in a certain section (for example, n = 10) is obtained. In FIGS. 9 and 10, for example, i = icv = 24, and it can be determined that the state has converged to the steady state. That is, the selection probabilities P (A, 24), P (B, 24), and P (C, 24) converge to 3.000%, 36.896%, and 60.104%, respectively. The emission probabilities of SSR, SR, and R based on the selection probability have converged to 3.000%, 17.000%, and 80.000%, respectively. Then, in the MCMC method, for example, a random value such that i = icv or more is obtained, and the state is changed as many times as the number of times corresponding to the value. The reason for obtaining a random value such that i = icv or more is to obtain a uniform distribution in a Markov chain having periodicity and no steady state as shown in FIG. 8 (D), for example. As described above, in the MCMC method, the state transition is repeated many times until it converges to the steady state, but in the present embodiment, when selecting the lottery table, for example, only one state transition (or a plurality of state transitions as described above) is performed. I try to do it.

2.2 Change processing, display processing In the present embodiment, for example, the selection condition change processing when selecting the first lottery table in step S12 of FIG. 6 is performed. For example, when a predetermined change condition is satisfied, the selection condition used when selecting the first lottery table from a plurality of lottery tables is changed. FIG. 11 is a flowchart illustrating an example of a process of changing the selection conditions of the lottery table.

First, the game system determines whether the change condition for the selection condition is satisfied based on the user's game status, game play status, item status, lottery status, time information, status information, and the like (step S21). The game status includes the progress status of the game, the status of the game results, the status of the game level, the status of the number of stages cleared, the status of the map of the game, the status of the environment, and the like. The game play status is the status of game operation, the status of the number and frequency of game play, the status of login, and the like. The item status is the usage status and possession status of the item. The lottery status is a situation such as a lottery result, for example, each lottery result in a continuous lottery or a lottery result in a lottery process different from the continuous lottery. Time information is information such as the current date, time, or period. The status information is the status information of the user, the user character, another user, or another user character. For example, the change condition is satisfied when the game progress reaches a predetermined progress, when the game result or game level reaches a predetermined result or level, or when the number of clears of the stage reaches a predetermined number of clears. It is judged that it was. Alternatively, change when the user performs a predetermined game operation, the number or frequency of game play reaches a predetermined number or frequency, or the number or frequency of user logins reaches a predetermined number or frequency. It is judged that the conditions have been met. Alternatively, when the user uses or possesses a predetermined item, it is determined that the change condition is satisfied. Alternatively, when the lottery result inside or outside the continuous lottery is a predetermined result, it is determined that the change condition is satisfied. Alternatively, if the current date, time, or period corresponds to a specific period, such as a campaign period, it is determined that the change conditions have been met. Alternatively, when the status such as the ability or level of the user, the user character, another user, or another user character reaches a predetermined status, it is determined that the change condition is satisfied.

In this way, the game system determines whether or not the change condition for the selection condition is satisfied, and if it is determined that the change condition is satisfied, executes the selection condition change process (steps S22 and S23). .. For example, the selection conditions such as the selection probability and the selection order of the lottery table are changed. For example, depending on the user's game status, game play status, item status, lottery status, time information, status information, etc., the selection conditions may be changed to be advantageous to the user, or conversely to be disadvantageous to the user. Change the selection criteria. For example, a change process is executed to increase or decrease the selection probability of a specific lottery table. Then, the game system displays information for making the user recognize that the selection condition has been changed (step S24). For example, an image, a character, a symbol, an effect, or the like for making the user recognize that the selection condition has been changed is displayed. Then, based on the selection conditions, the first lottery table is selected from the plurality of lottery tables (step S25). For example, when the selection condition is changed in step S23, the lottery table for the first time is selected based on the changed selection condition, and when the selection condition is not changed, the selection condition is not changed. Select the lottery table for the first time based on. Then, the game system executes the processes after step S13 in FIG.

FIG. 12 shows an example of displaying information that makes the user recognize that the selection condition of the lottery table has been changed. For example, in FIG. 12, the user is informed that the change condition for the selection condition is satisfied and the change process for increasing the selection probability of the lottery table TA for which the SSR is confirmed has been performed. For example, when the change condition is satisfied, the selection probability P (A) of the lottery table TA in FIG. 4 increases. In this way, when the selection probability P (A) of the lottery table TA from which the SSR is discharged increases, there is a chance that the SSR can be continuously acquired by the 10-series Gasha, so that the user is notified of this. By doing so, it is possible to give the user an effective motivation to play a continuous lottery such as 10 consecutive Gasha, and it is possible to improve the operating rate of the game system.

As described above, in the present embodiment, when the predetermined change conditions are satisfied, the selection conditions for selecting the first lottery table from the plurality of lottery tables are changed. In this way, the selection conditions of the lottery table will change in various ways according to various situations (game situation, game play situation, item situation, lottery situation, time information or status information) about the user. Therefore, it is possible to change the selection mode of the lottery table for the first time in various ways as compared with the case where the selection conditions such as the selection probability of the lottery table are uniformly determined. As a result, the fun of the lottery play can be improved, and the motivation for performing the lottery play can be given to the user. For example, in the present embodiment, if a specific game medium such as SSR is won in the first lottery process, the probability that the game medium is continuously won in the next lottery process can be increased. Therefore, the selection process of selecting the first lottery table from the plurality of lottery tables is important for the user's lottery play, and the selection conditions of this selection process change according to the user's situation. It is possible to give the user an effective motivation to perform the continuous lottery play.

Further, in the present embodiment, as shown in FIG. 12, a process of displaying information for making the user recognize that the selection condition has been changed is performed. For example, in FIG. 12, a display is performed to notify the user that the selection probability of the lottery table TA for which the SSR is confirmed has increased. Then, since it is an opportunity for the user to perform the lottery play of the 10-series Gasha at the timing when the selection probability of the lottery table TA increases in this way, it is possible to encourage the user to perform the lottery play of the 10-series Gasha. That is, by displaying such information, the user is satisfied with the predetermined change conditions, and the selection conditions for selecting the first lottery table from the plurality of lottery tables are changed. Can be visually recognized. Then, the user who visually confirms, for example, that the selection condition has been changed to a condition advantageous to the user, starts the continuous lottery play. For example, by displaying as shown in FIG. 12, the user has a high possibility of acquiring a specific game medium such as SSR in the first lottery process and continuously acquiring the game medium thereafter. You will be able to recognize it. Therefore, it is possible to give the user an effective motivation to perform the continuous lottery play.

In this embodiment, for example, as shown in A1 of FIG. 12, an icon for instructing the display of the emission probability of the game medium may be provided. For example, when the user selects the A1 icon, the emission probability of the game medium is displayed. Specifically, as described above, the user is displayed that the emission probabilities of SSR, SR, and R are 3%, 17%, and 80%, respectively. Then, when the selection condition such as the selection probability is changed as shown in FIG. 12, the emission probabilities of SSR, SR, and R after the change of the selection condition are displayed. More specifically, in the case of a continuous lottery such as 10 consecutive Gasha, the emission probability in each lottery is displayed.

For example, FIG. 13 is an explanatory diagram of a specific example when the selection probability of the lottery table is changed. In FIG. 13, the first selection probabilities P (A, 1), P (B, 1), and P (C, 1) are changed. For example, in FIG. 4, P (A, 1), P (B, 1), and P (C, 1) are 3%, 36.896%, and 60.104%, respectively, whereas in FIG. 13. Then, it is changed to 10%, 29.860%, and 60.104%. That is, the selection probability P (A, 1) of the lottery table TA for which the SSR is confirmed has increased from 3% to 10%. On the other hand, the selection probability P (B, 1) of the lottery table TB has decreased from 36.896% to 29.860%. As a result, as shown in FIG. 13, the emission probabilities of SSR, SR, and R become 10%, 14.187%, and 75.813%. Therefore, when the user selects the icon of A1 in FIG. 12 when the selection probability is changed in this way, the emission probabilities of SSR, SR, and R are 10%, 14.187%, and 75.813%. Is displayed to the user.

Then, as shown in FIG. 13, the selection probability of the lottery tables TA, TB, and TC and the discharge probability of SSR, SR, and R change every time the second, third, and fourth times. Then, as described with reference to FIGS. 9 and 10, the steady state is converged by repeating the number of times sufficiently. Therefore, if the selection probability of the first selection is changed in a continuous lottery such as 10 consecutive Gasha, the emission probabilities of SSR, SR, and R in each lottery will change. Therefore, in order to properly display the emission probability to the user, it is desirable to display the emission probability of SSR, SR, and R in each lottery of the continuous lottery to the user. That is, the emission probabilities of SSR, SR, and R at each time of FIG. 13 are displayed.

Further, in the present embodiment, a process of displaying information for causing the user to recognize how many times the lottery process is performed out of the n times lottery process according to the instruction of the n consecutive lottery is performed. For example, in FIG. 14, a continuous lottery instruction for 10 consecutive Gashas in which n = 10 is given. Then, in FIG. 14, information for making the user recognize that the third lottery process out of the n = 10 lottery processes is being performed is displayed. For example, in FIG. 14, the items that are the winning game media from the first to the third times are displayed, and the display portions of the items from the seventh to the tenth times are blacked out. As a result, the user can visually recognize that the third of the ten lottery processes of the 10-series Gasha has been performed. Therefore, the user can visually recognize how the game media are sequentially acquired by the lottery process performed according to the instruction of the continuous lottery, and can enjoy the continuous lottery play, and the continuous lottery play can be performed. Effective motivation can be given to the user.

Further, in the present embodiment, the transition condition is changed when a predetermined change condition is satisfied. Then, a process of displaying information for making the user recognize that the transition condition has been changed is performed. Further, in the present embodiment, when a predetermined change condition is satisfied, a process of changing the lottery condition of at least one lottery table of a plurality of lottery tables is performed. Then, a process of displaying information for making the user recognize that the lottery conditions have been changed is performed. FIG. 15 is a flowchart illustrating an example of processing for changing transition conditions and lottery conditions.

First, the game system selects the current lottery table from a plurality of lottery tables based on the selection conditions, and executes the lottery process using the selected lottery tables (steps S31 and S32). Then, it is determined whether the change condition for the transition condition or the change condition is satisfied based on the user's game status, game play status, item status, lottery status, time information, status information, and the like (step S33). Since these game statuses, gameplay statuses, item statuses, lottery statuses, time information or status information are the same as those described in step S21 of FIG. 11, detailed description thereof will be omitted below.

Then, when it is determined that the change condition for the transition condition or the lottery condition is satisfied, the game system executes the change process of the transition condition or the lottery condition (steps S34 and S35). For example, the game system changes the transition conditions such as the transition probability or the stay probability of the lottery table. Alternatively, as the transition condition change process, the transition status (transition configuration) of a plurality of lottery tables is changed. In addition, the game system changes the lottery conditions such as the lottery probability or the discharge order of the lottery table. Alternatively, as a process of changing the lottery conditions, a process of changing the game medium or the type of the game medium to be drawn, changing the group of the game media to be drawn, or changing the number of lottery or the like is performed. Then, the game system displays information for making the user recognize that the transition condition or the lottery condition has been changed (step S36). For example, an image, a character, a symbol, an effect, or the like for making the user recognize that the transition condition or the lottery condition has been changed is displayed.

Next, the game system determines whether or not to transition from the current lottery table to the transition destination lottery table based on the transition condition (step S37). For example, when the transition condition change processing is performed in step S35, it is determined whether or not to transition from the current lottery table to the transition destination lottery table based on the transition condition for which the change processing is performed. Then, the game system selects the next lottery table based on the determination result, and executes the lottery process using the selected next lottery table (steps S38 and S39). For example, when the lottery condition is changed in step S35, the lottery process is executed based on the lottery condition of the changed lottery table.

FIG. 16 is a flowchart when a process of changing the transition condition and the lottery condition of the lottery table is performed in the continuous lottery process such as 10 consecutive Gasha.

The game system executes the i-th lottery process using the i-th lottery table selected last time (step S41). Next, it is determined whether the change condition for the transition condition or the change condition is satisfied based on the user's game status, game play status, item status, lottery status, time information, status information, and the like (step S42). Then, when it is determined that the change condition for the transition condition or the lottery condition is satisfied, the change process for the transition condition or the lottery condition is executed (steps S43 and S44). Then, information for making the user recognize that the transition condition or the lottery condition has been changed is displayed (step S45). Next, the lottery table for the i + 1th time is selected based on the transition condition (step S46). Then, it is determined whether or not i = n has been reached, and if i = n has not been reached, i = i + 1 and the process returns to step S41 (steps S47 and S48). In this way, the processes of steps S41 to S48 are repeated until i = n is reached. Then, when i = n is reached, the game system returns the transition condition and the lottery condition to the initial state (step S49). That is, a process of returning the transition condition or the lottery condition changed by the change process of step S44 to the initial state before the n consecutive lottery is performed is performed, and the process ends.

As described above, in the present embodiment, when the change condition for the transition condition is satisfied, the transition condition of the lottery table is changed. In this way, the transition conditions of the lottery table will change in various ways according to various situations (game situation, game play situation, item situation, lottery situation, time information or status information) about the user. Therefore, it is possible to change the transition mode of the lottery table in various ways as compared with the case where the transition conditions such as the transition probability or the stay probability of the lottery table are uniformly determined. As a result, the fun of the lottery play can be improved, and the user can be given an effective motivation to perform the lottery play. For example, when the user's game status, game play status, or lottery status becomes a predetermined situation, the user uses a predetermined item, or the current date and time is a specific period, the transition condition is advantageous to the user. It will change to various conditions. For example, when the user's game performance or level is high, when the user uses a predetermined item, or during the campaign period, the probability of staying at a lottery table where a specific game medium such as SSR is discharged increases, or the relevant The transition probability of transitioning to the lottery table increases. This increases the possibility of acquiring a specific game medium such as SSR or continuously acquiring the game medium, and can give the user an effective motivation for performing the lottery play.

Further, in the present embodiment, when the change condition for the lottery condition is satisfied, the lottery condition of at least one lottery table of the plurality of lottery tables is changed. In this way, the lottery conditions of the lottery table will change in various ways according to various situations (game situation, game play situation, item situation, lottery situation, time information or status information) about the user. Therefore, it is possible to change the contents of the lottery process by the lottery table in various ways as compared with the case where the lottery conditions of the lottery table are uniformly determined. As a result, the fun of the lottery play can be improved, and the user can be given an effective motivation to perform the lottery play. For example, when the user's game status, game play status, or lottery status becomes a predetermined situation, the user uses a predetermined item, or the current date and time is a specific period, the lottery condition is advantageous to the user. It will change to various conditions. For example, in a lottery table where a specific game medium such as SSR or SR is discharged when the user uses a predetermined item or during a campaign period, the lottery probability of the game medium is high. Is increased, or the order of discharge is changed so that the game medium is easily discharged. This increases the possibility of acquiring a specific game medium such as SSR or SR, or continuously acquiring the game medium, and can give the user an effective motivation for performing the lottery play.

Further, in the present embodiment, as shown in FIG. 17, when the change condition is satisfied and the transition condition of the lottery table is changed, a process of displaying information for causing the user to recognize that the transition condition has been changed. I do. For example, in FIG. 17, a display is performed to notify the user that the transition probability to the lottery table TA for confirming the SSR has increased. For example, in FIG. 4, when the lottery table currently used is TB, a display is performed to notify the user that the transition probability Q (B, A) of TA has increased from the lottery table TB. For example, when the user uses a predetermined item or the user's game result or game level reaches a predetermined result or a predetermined level, the transition condition change condition is satisfied and the transition probability Q (B, A) increases. do. Then, the user is informed that it is an opportunity to transition from the lottery table TB to TA and acquire SSR. Alternatively, when the lottery table currently used is TC and the change condition is satisfied, a transition condition is generated such that a transition route from the lottery table TC to TA is generated as shown in FIG. 7 (B). May be changed. Then, as a display for the user to recognize that the transition condition has been changed, a display for notifying the user that the transition route from the lottery table TC to the TA has been generated may be performed. By doing so, it is possible to notify the user that the transition route for promotion to the lottery table TA for which the SSR is confirmed has been generated from the lottery table TC for which the SSR cannot be acquired. By displaying the above information, the user can visually recognize that the predetermined change condition is satisfied and the transition condition of the lottery table is changed. Then, for example, the user who visually confirms that the transition condition has been changed to a condition advantageous to the user will actively perform the next lottery play. For example, by displaying as shown in FIG. 17, when the lottery table used this time is TB, the user will actively perform the next lottery play, and it is effective to perform the lottery play. Motivation can be given to the user.

Further, in the present embodiment, as shown in FIG. 18, when the change condition is satisfied and the lottery condition of at least one lottery table of the plurality of lottery tables is changed, the user is notified that the lottery condition is changed. Performs processing to display information for recognition. For example, in FIG. 18, a display is performed to notify the user that the lottery probability of SR on the lottery table TB has increased. For example, in FIG. 4, when the lottery table currently used is TB, the lottery probability of SR is 0.4, but a display is displayed to inform the user that the lottery probability of 0.4 has increased. Will be. For example, when the user uses a predetermined item or the user's game result or game level reaches a predetermined result or a predetermined level, the conditions for changing the lottery conditions are satisfied, and the SR lottery probability increases. Then, the user is informed that it is an opportunity to acquire SR. By displaying such information, the user can visually recognize that the predetermined change condition is satisfied and the lottery condition of the lottery table is changed. Then, for example, the user who visually confirms that the lottery conditions have been changed to favorable conditions for the user will actively perform the lottery play, and the user will be effectively motivated to perform the lottery play. Can be given to.

Further, in the present embodiment, as shown in steps S42 to S44 of FIG. 16, even in the lottery process according to the instruction of n consecutive lottery such as 10 consecutive Gasha, if the predetermined change condition is satisfied, the transition condition is satisfied. Alternatively, the lottery conditions of at least one lottery table of the plurality of lottery tables are changed. Then, as shown in step S49, after the nth lottery process according to the instruction of the n consecutive lottery is completed, the changed transition condition or lottery condition is returned to the initial state. That is, while the lottery process is being performed n times, the transition condition and the lottery condition are changed from the conditions in the initial state by the change process in step S44. Therefore, when the lottery process is performed n times, the changed transition conditions and lottery conditions are returned to the original initial state conditions. That is, the transition condition and the lottery condition are reset. For example, when the transition probability or the stay probability, which is the transition condition, is changed, the transition probability or the stay probability is returned to the initial state probability. When the transition condition is changed, such as generating a new transition route, the transition route is deleted and the transition routes of the plurality of lottery tables are returned to the initial state routes. When the lottery probability and the discharge order, which are the lottery conditions, are changed, the lottery probability and the discharge order are returned to the initial probability and the order. In this way, when the next n consecutive lottery instructions are given, the lottery process can be started from the transition condition or the lottery condition in the initial state, and the lottery process can be executed appropriately. become.

Further, in the present embodiment, the game medium determined to be given to the user by the lottery process is excluded from the game media to be drawn in at least one lottery table of the plurality of lottery tables. For example, in FIG. 19A, the game medium IT1 which is an item is won by the lottery process using the lottery table TA. In this case, in the lottery table TA, the game medium IT1 is excluded from the game media (game media group) to be drawn. That is, in the next lottery process, the game medium IT1 is not subject to the lottery of the lottery table TA. Further, in FIG. 19B, the game medium IT1 is won by the lottery process using the lottery table TA, and the game medium IT1 is excluded from the game media to be drawn in the lottery table TA. Further, in FIG. 19B, even in the other lottery tables TB and TC, the game medium IT1 is excluded from the game media to be drawn. That is, in the next lottery process, the game medium IT1 is not a lottery target in all the lottery tables TA, TB, and TC.

As described above, by excluding the game media determined to be given to the user by the lottery process from the game media to be drawn, the same game medium is won when the continuous lottery process is performed. Therefore, it becomes possible to prevent a situation in which a game medium that is useless to the user is given to the user.

The process of excluding the game medium determined to be given to the user by the lottery process may be performed only during the current continuous lottery, or may be continued at the next continuous lottery. You may do it. That is, the game media excluded in this continuous lottery will also be excluded in the next continuous lottery. Alternatively, the process of excluding the game medium may be continuously performed until a specific game medium such as SSR is discharged. That is, until a specific game medium such as SSR is discharged, the process of excluding the game medium determined to be given to the user by the lottery process from the lottery target is continued, and the specific game medium is discharged. In that case, the excluded game medium is returned to the game medium to be drawn.

For example, as a specific example in which the process of excluding the game medium is performed only during the continuous lottery this time, in the case of a continuous lottery such as 10 consecutive gashas, only during the specified number of times of the continuous lottery (for example, n = 10). Enable the process of excluding game media. Alternatively, the process of excluding the game medium may be enabled only while staying at the current lottery table, and after transitioning to another lottery table, the process of excluding the game medium may be disabled and reset.

Further, for example, different types of game media such as SSR-α, SSR-β, and SSR-γ may be prepared as SSR. And depending on the game, the user may only want to collect the same type of game medium in the SSR. For example, you may only want to collect SSR-α. For example, by collecting a plurality of SSR-α, the user's character is sequentially strengthened. Further, for example, a growth limit may be set such that the character grows until K pieces of SSR-α are collected, but does not grow after that.

In this case, for example, after shifting to the lottery table TA for which the SSR is confirmed, only the same type of SSR may be discharged. For example, only SSR-α (a specific type of game medium in a broad sense) is discharged. Then, at this time, SSR-α may be continuously discharged until the lottery table TA is transitioned to another lottery table. Alternatively, SSR-α may be continuously discharged during a continuous lottery such as 10 consecutive Gasha. Alternatively, SSR-α may be continuously discharged until K pieces corresponding to the growth limit are reached. For example, until the number reaches K, only SSR-α is subject to the lottery, and SSR-β and SSR-γ are excluded from the lottery, but after reaching K, SSR-β and SSR-γ are also excluded. Be eligible for lottery. Alternatively, such a setting may be inherited at the next continuous lottery. For example, in the first 10-series Gasha, if the number of SSR-α did not reach K and was L (L <K), in the second 10-series Gasha, it reached this L. Take over so that SSR-α is continuously discharged until the number of SSR-α reaches from L to K.

FIG. 20 is an explanatory diagram of a method for realizing continuous discharge of a specific type of SSR. For example, in FIG. 20, the initial selection probability of the lottery table TA, TA', TA "in which SSR-α, SSR-β, and SSR-γ are fixed is as low as 1%. However, the lottery table TA. When is selected and SSR-α is won, the probability of staying at the lottery table TA is as high as 40.64%, which makes it easier for SSR-α to be continuously won. Similarly, the lottery tables TA'and TA When "" is selected and SSR-β and SSR-γ are won, the probability of staying at the lottery table TA'and TA "is high, so that SSR-β and SSR-γ are easily won consecutively. Since the transition probability between TA, TA', TA'is as low as 5.08%, the probability of shifting to the lottery table of another type of SSR after winning a specific type of SSR is low, and the same. It is easy for different types of SSRs to be won consecutively. From the lottery table TA, TA', TA', the transition to the lottery table TB is performed with a probability of 49.2%, and from the lottery table TB, the lottery table TA, TA', with a probability of 1.333%. , TA ”is promoted.

The probabilities shown in FIG. 20 and the like are rounded to the fourth decimal place. Therefore, for example, the transition probability (1.333%) for each of the lottery table TB to the lottery table TA, TA', TA ”, the stay probability of the lottery table TB (65%), and the transition probability to the lottery table TC ( The total of 1.333% × 3 + 65% + 31% (31%) is not 100%, but it is actually 100%. The same applies to other parts.

Further, in the present embodiment, a process of displaying information for making the user recognize the transition status of a plurality of lottery tables is performed. For example, in FIG. 21, when a user starts a lottery play of Gasha, a plurality of lottery tables TA, TB, TC used in the Gasha, a transition probability, a stay probability, and a lottery for the lottery tables TA, TB, TC are drawn. The probability, the selection probability, the transition configuration of the lottery tables TA, TB, and TC, and the like are displayed to the user as the transition status. By doing so, the user can see the transition status of the displayed lottery table, and see the lottery table being used, the transition probability of each lottery table, the stay probability, the lottery probability, the selection probability, and the lottery table. You will be able to visually recognize the transition configuration (connection configuration) of. Therefore, the user can perform lottery play such as continuous lottery play while checking the transition status of the displayed lottery table, and the convenience of the user can be improved. As described above, when the predetermined conditions are satisfied, the transition probability, stay probability, lottery probability or selection probability of the lottery table changes, and FIGS. 4 to 7 (A), 7 (B) and 8 show. When the transition configuration of the lottery table changes as shown in (A) and 8 (B), it is desirable to display the changed state to the user in real time. In this way, the user can formulate a lottery play strategy while observing the transition status of the lottery table that changes in real time, and can further improve the fun of the lottery play.

Further, in the present embodiment, a process of displaying information for causing the user to recognize the current lottery table used for the lottery process is performed. For example, in FIG. 22, the lottery table TA for which the SSR is confirmed is currently staying, and the user is notified that the lottery table used this time is the TA. Then, the probability of staying at the lottery table TA is as high as 50.8%, and the user is informed that it is a chance to continuously acquire SSR. In this way, the user can visually recognize the status of the current lottery table used for the current lottery process. Therefore, the user can perform lottery play such as continuous lottery play while checking the status of the lottery table used this time, and the convenience of the user can be improved. For example, when the user is staying at a lottery table where a specific game medium such as SSR is discharged, the user continues the lottery play, and when staying at a lottery table where useful game media is not discharged, the user is staying at the lottery table. It becomes possible to formulate strategies such as stopping the lottery play, and the fun of the lottery play can be further improved.

The transition status shown in FIGS. 21 and 22 and the status of the lottery table this time may be displayed according to a user's operation instruction, or may be displayed at the timing of each lottery of the continuous lottery, and displayed according to a predetermined schedule. You may try to do it.

Further, in the present embodiment, a process of displaying information for making the user recognize that the game medium having a predetermined attribute is continuously assigned is performed. For example, in FIG. 23, a display is performed to notify the user that the quadruple combo of SSR has been achieved and SSR, which is a game medium having a predetermined attribute, has been continuously assigned. For example, staying at the lottery table TA in FIG. 4 is displayed to notify the user that four SSRs have been continuously discharged in four consecutive lottery processes out of 10 consecutive Gasha. By doing so, the user who sees the display of FIG. 23 will be motivated by the continuous addition of the game medium having the predetermined attribute, and will continue the lottery play, and the lottery play will be performed. It becomes possible to give the user an effective motivation to do. For example, the user will aim for a 10-series combo of SSRs in which SSRs are discharged in all lottery processes of 10-series Gasha, and it will be possible to give an effective motivation for performing continuous lottery play.

As described above, in the present embodiment, various information regarding the selection condition, the transition condition, and the lottery condition is displayed to the user. By doing so, for example, the manufacturer that provides the lottery game can fulfill the accountability to the user about the lottery game such as Gasha. For example, in order to fulfill the accountability, it is desirable to display the actual emission probability and the like to the user as described above. For example, not only the transition status of the lottery table as shown in FIG. 4 is displayed, but also the emission probabilities of SSR, SR, and R set by the transition conditions of 3%, 17%, and 80% are displayed to the user.

Further, in the present embodiment, the lottery process such as the continuous lottery process is performed by using the probability distribution of the game medium acquired and expanded based on the transition process of the lottery table without executing the transition process of the lottery table in real time. It is also possible. Further, in the above, the transition probability and the stay probability have been described as examples of the transition conditions, but the present embodiment is not limited to this. For example, if a specific game medium such as a centerpiece card in Box Gasha is prepared and the specific game medium is won, the transition condition may be such that the game transitions to another lottery table. Alternatively, in a Gasha that can be played by lottery as a login bonus every day, if the points earned for the event being held by the Gasha exceeds a predetermined value, the game will transition to another lottery table in the lottery play of the login bonus after that timing. It may be a transition condition.

Further, in Gasha with such a login bonus, for example, a lottery process may be performed at the time of login, and the lottery table of the transition destination may be displayed to the user after the lottery process. Alternatively, although the transition process to another lottery table is performed after the lottery process, the lottery table of the transition destination may not be displayed to the user. Then, when logging in the next day, the lottery table of the transition destination is displayed to the user. Alternatively, the transition process to another lottery table may be performed at the time of login, and the lottery process may be performed after the transition process. Then, even when logging in the next day, the transition process to another lottery table is performed, and the lottery process is performed after the transition process.

Further, in the present embodiment, the case where a plurality of lottery tables are prepared in advance has been described as an example, but the lottery table used for the lottery process may be automatically generated. For example, a lottery table is automatically generated each time each lottery play of continuous lottery is started. For example, in the initial state, only the lottery table TA is prepared, but when the lottery play of the continuous lottery starts, the lottery table TA is duplicated to generate the lottery table TB, and the emission probability of the game medium for the lottery table TB is set. do. In addition, the transition probability and the stay probability for the lottery table TB are set. By doing so, a new lottery table will be generated in real time each time the lottery play is performed. Alternatively, for example, a lottery table having a transition configuration as shown in FIGS. 7 (A) to 7 (C) and 8 (A) to 8 (C) is automatically generated from the lottery table having the transition configuration shown in FIG. It may be. By doing so, it becomes possible to automatically generate a lottery table having a lottery configuration of various modes, and it becomes possible to improve the fun and strategy of the lottery play.

Although the present embodiment has been described in detail as described above, those skilled in the art will easily understand that many modifications that do not substantially deviate from the novel matters and effects of the present disclosure are possible. Therefore, all such variations are included in the scope of the present disclosure. For example, a term described at least once in a specification or drawing with a different term in a broader or synonymous manner may be replaced by that different term anywhere in the specification or drawing. Further, the selection process of the lottery table, the process of changing the selection condition, the transition condition, the lottery condition, the lottery process, the game process, the display process of various information, etc. are not limited to those described in the present embodiment, and are equivalent to these. Techniques are also included within the scope of this disclosure.
