In this medal game device, lottery is performed by inserting medals, and a predetermined number of medals are released into the game space at the time of winning. Then, the medals are pushed out by the pushing member in the game space, and the medals that have dropped into the medal drop opening are paid out. In addition, the medal game device changes the lottery probability by an amount corresponding to the difference between the preset target payout rate and the payout rate calculated from the actual medal balance and the current date. Yes.

Japanese Patent No. 5178556

  However, the change of the lottery probability performed in the above-described medal game device is intended to converge the actual payout rate to the target payout rate in consideration of only the situation on the game device operator side. Is not taken into account. The change of the lottery probability as described above causes a state (time zone) in which it is extremely difficult to win, lowers the user satisfaction, and is disadvantageous for the management side.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a game machine capable of converging to a payout rate and enhancing the interest of a user.

  A game machine according to an aspect of the present invention includes an insertion slot into which a play medium is inserted, a placement surface on which the entered play medium is placed, and the play medium placed on the placement surface. A movable plate that is pushed out toward the dropping unit, a donating unit that provides the user with the game media that has fallen into the dropping unit, at least the number of the game media that has been inserted into the slot, and the game medium that has been provided to the user The management means for managing the payout rate based on the above, the payout rate setting means for setting the target payout rate, the first game for performing the first lottery by satisfying the first condition, and winning the first lottery Based on the result, the first game executing means for supplying the game medium to the placement surface described above, and the second game for performing the second lottery by satisfying the second condition, and based on the winning result of the second lottery The game media Based on calendar information or user information, second game execution means to be supplied to the placement surface and ease of supply of the game medium in the first game and the second game without changing the target payout rate And balance setting means for setting.

  There are various customers who visit the store operating the medal game device, but the tendency of each customer's preference for the game can be classified according to calendar information such as day of the week and time of day or user information. Therefore, according to said structure, game property can be varied with calendar information or user information by changing the ease of supply of the play medium in a 1st game and a 2nd game. As a result, a game according to the tastes of various customers can be realized.

  In this game machine, the second game may be executed instead of the first game by satisfying a predetermined condition during the execution of the first game.

  In this game machine, when the balance setting means sets the ease of supply of the game medium in the second game to be relatively higher than the ease of supply of the game medium in the first game, The second game execution means may make the winning probability of the second lottery in the second game relatively higher than the winning probability of the first lottery.

  Furthermore, in this game machine, when the balance setting means sets the ease of supply of the game medium in the second game to be relatively higher than the ease of supply of the game medium in the first game, The first game execution means may increase the probability that the predetermined condition is satisfied during the execution of the first game.

  In this game machine, the calendar information may include at least one of a day of the week, a date, and a time zone. For example, there is a tendency that the preference of the user who plays the game machine varies depending on the day of the week such as weekends and weekdays, the date of holidays, and the time zone such as morning and afternoon. Therefore, according to the above configuration, by changing the ease of supply of game media according to this tendency, the user's interest can be improved without substantially changing the payout rate.

  ADVANTAGE OF THE INVENTION According to this invention, while converging to a payout rate, the game machine which can improve a user's interest property is realizable.

  The above object, other objects, features, and advantages of the present invention will become apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings.

1 is a perspective view schematically showing a game machine according to an embodiment of the present invention. It is a functional block diagram which shows the structure of the game machine of FIG. 1 schematically.

(Embodiment)
Hereinafter, the game machine 100 according to the embodiment of the present invention will be described. Note that the game machine 100 is played by a user using a medal as a play medium. The game machine 100 can perform a lottery or the like that allows a predetermined number of game media to be paid out by winning a predetermined prize.

<Game console configuration>
As shown in FIGS. 1 and 2, the game machine 100 includes a display unit 10, an operation unit 20, a pusher game unit 30, and a control unit 40. These are connected via a bus 50 so that they can communicate with each other.

  The display unit 10 is a display device and has a screen for displaying an image. The operation unit 20 is a part operated by a user, and includes an insertion port 21, a payout port 22, and an input unit 23. A game medium such as a medal is inserted into the pusher game unit 30 from the insertion slot 21 by the user. The insertion port 21 is provided with a first sensor 24 for detecting the inserted game medium. The game medium is paid out of the game machine 100 (outside the machine) from the pusher game unit 30 through the payout port 22. The payout port 22 is provided with a second sensor 25 that detects a game medium paid out from the payout port 22. The input unit 23 is a device to which a signal is input by a user operation, such as a button and a lever for playing a game or the like.

  The pusher game unit 30 includes a placement surface 31, a movable plate 32, a third sensor 33, a side groove (not shown), and a drop unit 34. The placement surface 31 is provided in the game machine 100 (inside the machine), and a play medium is placed on the placement surface 31. The movable plate 32 reciprocates in the front-rear direction on the placement surface 31, and pushes the game medium on the placement surface 31 toward the dropping portion 34 in front of the placement surface 31. On the movable plate 32, a game medium fed from the slot 21 and a game medium supplied by winning each lottery are given. Note that the game medium itself inserted from the insertion slot 21 may be supplied onto the movable plate 32, or the same number of game media input from the insertion slot 21 may be supplied. Good.

  The game medium falls on the placement surface 31 from the reciprocating movable plate 32 and is supplied to and placed on the placement surface 31. Then, the game medium on the placement surface 31 falls by the movable plate 32 to the side groove and the drop part 34 on the side of the placement surface 31. Among these, the game medium that has fallen on the dropping unit 34 is paid out to the payout port 22 and provided to the user. Further, the third sensor 33 is provided, for example, in a chucker attached to the side surface of the movable plate 32, and detects a game medium that passes through the chucker from the movable plate 32 and falls to the placement surface 31.

  The control unit 40 includes a calculation unit 41 such as a CPU and a storage unit 42 such as a ROM and a RAM. The storage unit 42 stores a program necessary for the game machine 100 to function, various data referred to when the program is executed, and the like. The calculation unit 41 reads this program from the storage unit 42 and executes it, so that the control unit 40 controls the operation of each unit. The control unit 40 may be configured by a single control device that performs centralized control, or may be configured by a plurality of control devices that perform distributed control in cooperation with each other.

<Functional configuration of game console>
As shown in FIG. 2, the control unit 40 includes a game execution unit 43, a balance setting unit 44, a management unit 45, and a payout rate setting unit 48. The control unit 40 may further include a counting unit 46 and a correcting unit 47. Each of these means included in the control unit 40 operates based on detection signals output from the first sensor 24, the second sensor 25, and the third sensor 33. That is, the control unit 40 advances the game according to the behavior of the play medium.

  The game execution means 43 has a first game execution means 43a and a second game execution means 43b. The first game executing means 43a executes the first game for performing the first lottery, and the second game executing means 43b executes the second game for performing the second lottery. The first game and the second game will be described later.

  The counting means 46 counts the number of play media (insertion number I) input from the input port 21 based on the detection signal from the first sensor 24. Further, the counting means 46 counts the number of game media provided from the payout opening 22 (provided number N) based on the detection signal from the second sensor 25. The number N of the play media provided is the total number of the first donation number Ni and the second donation number Nw. The first donation number Ni is the number of game media that have been thrown into the pusher game unit 30 from the slot 21 and pushed out by the movable plate 32. The second donation number Nw is the number of game media supplied to the pusher game unit 30 and pushed out by the movable plate 32 by winning each lottery.

The management means 45 calculates and manages the payout rate (actual value) from the number I and number N of game media counted by the counting means 46 as shown in the following formula (1). The payout rate is a ratio of the number of game media provided N to the number of game media input I.
PO = N / I = (Ni + Nw) / I (1)

  The correcting means 47 performs a winning probability correction process for correcting the winning probability of each lottery in order to converge the actual value of the payout rate to the target value (target payout rate). This target payout rate is set by the payout rate setting means 48 in response to an input by the operator of the game machine 100 or as a predetermined value, for example, every 1% in the range of 75% to 100%. Details of the winning probability correction process will be described later.

  The winning probability of each lottery is the number of wins with respect to the number of lotteries (number of executions) executed within a predetermined period by the game execution means 43 in each game. The winning probability (second winning probability) of the second lottery is different from the winning probability (first winning probability) of the first lottery, and is set to a probability higher than the first winning probability, for example.

  The balance setting means 44 sets the ease of supply of game media in the first game and the second game based on the calendar information without changing the target payout rate. The ease of supply is determined by, for example, the winning probability, the number of game media supplied to the placement surface 31 by one winning, or the number of times each game is executed in each lottery of the first game and the second game. is there. Details of the processing (supply setting processing) by the balance setting unit 44 and calendar information will be described later.

  In the following, the ease with which the game medium is supplied is represented by the ratio of the first supply number to the second supply number. This first supply number is the ease of supply of game media in the first game, and is the number of game media supplied by winning the first lottery when a predetermined number of game media are inserted. The second supply number is the ease of supply of game media in the second game, and is the number of game media supplied by winning the second lottery when a predetermined number of game media are inserted. The first supply number and the second supply number depend on, for example, the winning probability of each lottery, the number of game media by one winning, and the execution probability of each game.

  Further, the supply setting process by the balance setting unit 44 is performed independently of the winning probability correction process by the correction unit 47. In this winning probability correction process, the absolute number of the total number of the first supply number and the second supply number varies based on the difference between the actual value of the payout rate and the target payout rate (difference value of the payout rate). On the other hand, in the supply setting process, the ratio between the first supply number and the second supply number varies based on the calendar information, but the absolute value of the total number of the first supply number and the second supply number does not vary. .

<First game and second game>
In the first game, the first lottery is performed by satisfying the first condition, and the game medium is supplied to the placement surface 31 based on the winning result of the first lottery. In the second game, the second lottery is performed by satisfying the second condition, and the game medium is supplied to the placement surface 31 based on the winning result of the second lottery. Examples of the first lottery and the second lottery include a lottery game such as a slot game, and various challenge games using the slot 21 and the input unit 23.

  In the present embodiment, the second game is a game that is executed in place of the first game by satisfying a predetermined condition during the execution of the first game, and the first game and the second game are alternatives. To be executed. For this reason, which game the game execution means 43 executes is determined by whether or not a predetermined condition is satisfied, for example.

  For example, the execution probability of the second lottery of the second game is set lower than the execution probability of the first lottery of the first game. For this reason, the degree of difficulty for executing the second lottery is higher than that of the first lottery. This execution probability is a ratio between the number of executions of the first lottery and the number of executions of the second lottery, and is the number of executions of each lottery with respect to the total number of executions of all the lotteries within a predetermined period.

  Hereinafter, the first game is described as a game performed in the normal mode, and the second game is described as a game performed in the establishment variation mode. This normal mode is a mode that is not a probability variation mode, and is a probability variation challenge mode that challenges the transition to the probability variation mode.

  The case where a slot game is played as each lottery will be described below. In this case, the game execution unit 43 displays a plurality of reel images arranged vertically, horizontally, and diagonally on the display unit 10. When a medal enters the chucker of the pusher game unit 30, the game execution unit 43 rotates and displays the reel image in response to the detection signal from the third sensor 33. Furthermore, the game execution means 43 displays the reel image that rotates at a predetermined timing so as to stop. The game execution means 43 supplies a prize according to the combination pattern of the reel images that are stopped and displayed.

  For example, eight numbers 1 to 8 are displayed as a reel image. When the lottery is won, the reel image pattern is aligned in any of a plurality of lines in which a plurality of reel images are arranged vertically, horizontally, and diagonally. Then, the game execution means 43 supplies a winning prize (a prize assigned to a reel image having a uniform pattern).

  In the first lottery of the first game, the game execution means 43 supplies a predetermined number of game media when the winning prize (reel image with the symbols) is “1”, “3” or “5”. Thereby, the game medium is supplied to the placement surface 31 via the movable plate 32 of the pusher game unit 30. In addition, the game execution means 43 increases the number of player characters appearing on the screen. As the number of player characters appearing increases, the number of game media supplied in the next slot game increases. Here, when the number of appearances of the player characters reaches a predetermined number, the game executing means 43 executes a predetermined first challenge game.

  When the first challenge game is successful (winning), the game execution means 43 shifts from the first game to the second game. Thereby, the winning probability in the slot game after the next time becomes the second winning probability, which is higher than the current first winning probability for a predetermined period. For this reason, it is easy for the user to acquire a lot of game media.

  Further, when the winning prize (reel image with the symbols arranged) is “7”, the game executing means 43 executes the second game without passing through the first challenge game.

  When the winning prize (reel image with the symbols) is “2”, “4” or “6”, the game execution means 43 supplies a predetermined number of game media and reduces the number of player characters appearing. .

  When the winning prize (reel image with the symbols arranged) is “8”, the game execution means 43 supplies a predetermined number of game media and maintains the number of player characters appearing unchanged.

  When a predetermined condition is satisfied while the slot game is being executed, the game executing means 43 may execute a predetermined “second challenge game”. This second challenge game is a game in which an enemy character displayed on the screen is subjugated to acquire a play medium. Specifically, the game execution means 43 reduces the physical strength value of the enemy character according to the number of game media inserted from the insertion slot 21. When this physical strength value becomes zero, the game execution means 43 shifts from the first game to the second game, assuming that the second challenge game is successful (winning).

  In the second lottery of the second game, as in the first lottery of the first game, a prize according to the winning prize (reel image with the symbols arranged) is supplied. It should be noted that when the second lottery is executed, “7” is won (the reel image pattern is aligned with “7”), and when the first challenge game is successful (winning), the game execution means 43 Causes the second game to occur continuously.

  The game execution unit 43 determines that the first game and the second game are easily supplied with the game medium by the supply setting process of the balance setting unit 44 and the winning probabilities of the winning probability correction process of the correction unit 47. Run based on.

<Winning probability correction process>
Next, the winning probability correction process for correcting the first winning probability and the second winning probability based on the difference value of the payout rate will be described. In this winning probability correction process, the correcting means 47 corrects the winning probabilities in each lottery of the first game and the second game by increasing or decreasing so that the difference value of the payout rate approaches zero. The correction amount (increase / decrease value) of each winning probability at this time is determined in advance according to the difference value of the payout rate and stored in the storage unit 42. And the correction means 47 acquires the difference value of payout rate at a predetermined timing, refers to the data in the storage unit 42 based on the difference value, and corrects each winning probability in each lottery. As a result, the actual value of the current payout rate can be brought closer to the target value in the future.

  More specifically, in the winning probability correction process, the correction means 47 displays the reel image symbol (“1”, “2”, “3”, “4” in the above lottery example) that awards the supply of game media. ”,“ 5 ”,“ 6 ”,“ 8 ”), the probability (each winning probability) varies according to the difference value of the payout rate.

  For example, when the actual value of the payout rate is larger than the target value, the correction unit 47 performs correction to reduce the first winning probability and the second winning probability that award the supply of game media. As a result, the number of game media supplied to the placement surface 31 decreases, and the second number of game media provided from the placement surface 31 to the payout port 22 decreases. For this reason, the actual value of the payout rate, which is the ratio of the number of game media provided to the number of game media input, approaches the target value.

  On the other hand, when the actual value of the payout rate is smaller than the target value, the correction means 47 performs correction to increase the first winning probability and the second winning probability that award the supply of the game medium. As a result, the supply number of game media, and hence the second supply number of game media, increases, and the actual value of the payout rate approaches the target value.

  In addition, as the difference value of the payout rate is smaller, the correction means 47 reduces the fluctuation range of each winning probability that awards the supply of game media, so that the actual value of the payout rate does not deviate from the target value. On the other hand, as the difference value of the payout rate is larger, the correcting means 47 increases the fluctuation range of each winning probability that awards the supply of game media, so that the actual value of the payout rate approaches the target value quickly.

  As described above, the first winning probability and the second winning probability with the play medium as a prize vary according to the difference value of the payout rate. As a result, the sum of the first donation number and the second donation number is changed, and the donation number is changed, and the actual value of the payout rate converges to the target value. Moreover, the change width of each winning probability is not changed by the calendar information. For this reason, a state where it is extremely difficult to win due to the calendar information does not occur, the user's satisfaction is not lowered, and the user's interest can be enhanced.

<Calendar information>
The calendar information is information classified by time, and includes at least one of a day of the week, a date, and a time zone. Depending on the calendar information, the type (customer class) of the user of the game machine 100 tends to be different. As the types of users, for example, a new user who plays the game machine 100 for the first time or has a small number of plays, and a regular user who has a large number of plays and is familiar with the contents of the game machine 100 can be considered.

  Calendar information can be roughly divided into three time groups (first to third time groups) according to the ratio of these new users and regular users. Among these, the second time group is a time when the deviation of the play ratio between the new user and the regular user is the smallest and becomes a reference time. The first time group is a time when the play ratio of new users is higher than that of the second time group, and the third time group is a time when the play ratio of regular users is higher than that of the second time group.

  The reference second time group includes Monday to Wednesday from the viewpoint of the day of the week and date, and includes the afternoon time zone of the day from the viewpoint of the time zone. The first time group with many new users includes Saturday and Sunday, which are weekends, and holidays, and includes the morning time zone in one day. In addition, when a special setting date such as Thanksgiving Day is determined in advance by the operator of the game device 100 or the like according to the installation location of the game device 100, such a special setting date is also assigned to the first time group. May be included. And as a 3rd time group with many regular users, Thursday and Friday are included, and the time zone at night is included in one day.

<Supply setting process>
Next, a supply setting process for changing the ease of supply of game media based on calendar information, independent of the payout rate, will be described. In this supply setting process, the balance setting means 44 changes the ease of supply of game media according to the time group of the calendar information to which the current time belongs.

  That is, the ease with which the game medium is supplied (ratio between the first supply number W1 and the second supply number W2) is divided into, for example, three step ratios (first to third step ratios) in advance. These three stage ratios are respectively associated in advance with three time groups (first to third time groups) of the calendar information.

  The second stage ratio is a reference ratio among the supply number stage ratios, for example, W1: W2 = 3: 2, and is associated with the reference second time group of the time groups. . The first stage ratio is such that the ratio of the first supply number W1 to the second supply number W2 is higher than the second stage ratio, for example, W1: W2 = 4: 1, and is associated with the first time group. Yes. The third stage ratio is such that the ratio of the second supply number W2 to the first supply number W1 is higher than the second stage ratio, for example, W1: W2 = 1: 4, and is associated with the third time group. Yes.

  The balance setting means 44 compares the current date / time data with the calendar information. As a result of the comparison, the balance setting means 44 obtains the time group of the calendar information to which the current date / time data belongs, and determines the stage ratio of the supply number corresponding to this time group. In the game execution means 43, the first winning probability and the second winning probability that award the transition to the second game are changed so as to become the step ratio of the determined supply number.

  For example, when the current date / time data changes from the first time group of calendar information to the second or third time group, the supply rate stage ratio is set to the first stage ratio to the second or third stage ratio. Changed to Further, when the current date / time data changes from the second time group to the third time group, the stage number ratio of the supply number is changed from the state set to the second stage ratio to the third stage ratio. In these cases, the second supply number is larger than the first supply number in the step ratio of the supply number.

  For this reason, in the first game, the game execution means 43 increases the first winning probability of winning the transition to the second game. The increase in the first winning probability includes an increase in the winning probability of the symbol “7” on the reel image, an increase in the winning probabilities of the symbols “1”, “3”, “5” and the first challenge game, and the second challenge game. Increase in the winning probability and decrease in the winning probability of symbols “2”, “4”, and “6”. Note that the game shifts from the first game to the second game due to the success (winning) of the first and second challenge games performed in the first game. For this reason, the winning probability of each challenge game during execution of the first game is also included in the first winning probability of the first game.

  In this way, the execution probability of the second game increases due to the increase in the first winning probability that makes the transition to the second game a prize. Thereby, the ratio of the number of times of execution of the second game to the number of times of execution of the first game increases, and the second supply number with respect to the first supply number increases.

  Further, in the second lottery of the second game, the game execution means 43 increases the second winning probability of winning the transition to the second game (continuous execution of the second game). The increase in the second winning probability includes an increase in the winning probability of the symbol “7” in the reel image, an increase in the winning probabilities of the symbols “1”, “3”, “5” and the first challenge game, and the symbol “7”. There is a decrease in the winning probability of “2”, “4”, and “6”. The winning probability of the first challenge game during execution of the second game is also included in the second winning probability of the second game.

  Thereby, the second game is continuously performed by winning the prize for the transition to the second game in the second game, and the execution probability of the second game is increased. For this reason, the ratio of the number of executions of the second game to the number of executions of the first game increases, and the second supply number with respect to the first supply number increases.

  In this way, the ratio of the number of times of execution of the second game to the number of times of execution of the first game is set higher than that in the second time group. Thereby, in the 3rd time group which tends to have many regular users, the frequency | count of execution in a 2nd game becomes larger than the case of a 2nd time group. Therefore, the regular user accustomed to the game can challenge and enjoy the second game such as the second game, which is relatively more difficult than the first lottery of the first game.

  On the other hand, when the current date / time data changes from the third time group of the calendar information to the first or second time group, the supply rate step ratio is set to the third step ratio from the first or second step. Changed to step ratio. Further, when the current date / time data changes from the second time group to the first time group, the stage number ratio of the supply number is changed from the state set to the second stage ratio to the first stage ratio. In these cases, the first supply number is larger than the second supply number in the step ratio of the supply number.

  For this reason, in the first lottery of the first game, the game execution means 43 lowers the first winning probability of winning the transition to the second game. The decrease in the first winning probability includes a decrease in the winning probability of the reel image symbol “7”, a decrease in the winning probability of the first challenge game, a decrease in the winning probability of the second challenge game, and the symbol “2”. There is an increase of “4” and “6”. As described above, due to the decrease in the first winning probability with the shift to the second game as a prize, the execution probability of the second game decreases, and the first supply number with respect to the second supply number increases.

  In the second lottery of the second game, the game execution means 43 lowers the second winning probability of winning the transition to the second game (continuous execution of the second game). The decrease in the second winning probability includes a decrease in the winning probability of the symbol “7” of the reel image, a decrease in the winning probability of the first challenge game, and the winning probabilities of the symbols “2”, “4”, and “6”. There is a rise. Thereby, due to a decrease in winning of the prize for transition to the second game in the second game, the execution probability of the second game decreases, and the first supply number with respect to the second supply number increases.

  Thus, the ratio of the number of times of execution of the first game to the number of times of execution of the second game is made higher than that in the second time group. Thereby, in the 1st time group in which there are many new users, the frequency | count of execution in a 1st game increases more than the case of a 2nd time group. Therefore, even a new user who is unfamiliar with the game can easily enjoy the first game, which is relatively less difficult than the second game.

  In this way, the ratio of the supply number is changed based on the calendar information. As a result, the ratio of the number of executions of the first game and the second game changes. For this reason, the game nature of the 1st game in the game machine 100 and the 2nd game can be varied according to the user's customer's taste which changes with calendar information. As a result, a game according to the tastes of various customers can be realized.

  For example, in the case of winning the symbols “1”, “3”, and “5”, the game medium is supplied together with the transition to the second game. For this reason, the ratio between the first supply number and the second supply number fluctuates due to the shift to the second game, and the total number of the first supply number and the second supply number by the supply of the game medium (the absolute number of game media) Number, and thus the number of grants) will also vary. Since the actual value of the payout rate varies due to the variation in the total number, the winning probability correction process is performed so that the actual value approaches the target value.

<Modification 1>
In the above-described embodiment, the balance setting unit 44 sets the ease of supply of game media in the first game and the second game based on the calendar information, but is not limited to this. For example, the balance setting unit 44 may set the ease of supply of game media in the first game and the second game based on the user information. This user information can be acquired as follows, for example.

  The game machine 100 or each satellite thereof is equipped with a card reader. The user owns an IC card in which data such as personal information and game history is stored, and holds the IC card over the card reader when starting the game. Thereby, the control part 40 of the game machine 100 reads the data memorize | stored in the IC card, and acquires user information. Based on this information, the control unit 40 determines whether the user playing at each satellite is a new user or a regular user. And the balance setting means 44 sets the ease of supply of the game media in a 1st game and a 2nd game based on the ratio of a new user and a regular user.

  In this case, the balance setting unit 44 sets the ease of supply of the game medium based on the ratio between the new user and the regular user in the user information, but the present invention is not limited to this. For example, the balance setting means 44 may determine the gender ratio and the age group ratio from the user information, and set the ease with which the game medium is supplied based on the ratio.

  Furthermore, the medium for acquiring user information is not limited to an IC card. The control unit 40 may acquire user information using a mobile terminal or the like.

<Modification 2>
In the above embodiment, the game machine 100 has been described in which the first lottery in the normal mode can be executed as the first game and the second lottery in the probability variation mode can be executed as the second game. However, the contents of the first game and the second game are not limited to the above games. For example, the first game and the second game may be games with different difficulty levels.

  For example, in the game machine 100, the game execution means 43 executes a normal mode normal lottery, a probability variation mode normal lottery, a mini game, and a JP lottery. At least two of these games may be the first game and the second game. The normal lottery is a lottery such as the slot game described above.

  The mini game is executed, for example, when the cumulative number of medals inserted from the insertion slot 21 reaches a predetermined number. As the mini game, a timing game in which the user operates the input unit 23 of the operation unit 20 in accordance with the image displayed on the display unit 10 can be employed. In this mini game, a predetermined number of medals and a predetermined item are supplied as success when a predetermined condition is satisfied.

  The JP lottery is a lottery in which more game media are paid out than the normal lottery by winning, and a lottery device such as a roulette is used. For example, the game execution means 43 displays on the display unit 10 an image of roulette rotation in which images of a plurality of enemy characters (attributes) are arranged. At the timing when the lottery ball enters the pocket of the lottery device, the game execution means 43 displays on the display unit 10 so that the rotating roulette stops. At this time, a prize corresponding to the enemy character located in the vicinity of the instruction mark displayed on the display unit 10 is won. For example, a payout value obtained by adding an additional value corresponding to the number of inserted medals to a predetermined initial value is determined, and a game medium having a payout value is supplied.

  The JP lottery is executed when a predetermined condition such as winning a lottery (preliminary lottery) performed in advance is satisfied. In the preliminary lottery, a lottery device such as a roulette is used. When a lottery ball enters one of the plurality of pockets of the lottery apparatus, the prize assigned to the entered pocket is won. As a result, the right to play the JP lottery is supplied.

  The difficulty level of the normal lottery in the normal mode, the normal lottery in the probability variation mode, the mini game, and the JP lottery may be set according to the number of game media supplied when winning or succeeding. For example, the greater the number of game media that are supplied, the higher the difficulty level of the game. For example, among these, the difficulty level of the mini game may be the lowest and the difficulty level of the JP lottery may be set the highest.

(Other embodiments)
In the embodiment described above, the balance setting unit 44 sets, for example, the ease with which the game medium is supplied in the second game to be relatively higher than the ease with which the game medium is supplied in the first game. As a result, the first game execution means 43a increases the probability of satisfying the predetermined condition during the execution of the first game, and makes it easier to shift from the first game to the second game. On the other hand, the second game execution means 43b may make the winning probability of the second lottery in the second game relatively higher than the winning probability of the first lottery in the first game.

  In the above embodiment, the game execution means 43 receives each transition to the second game as a prize according to the ratio (for example, the first to third stage ratios) between the first supply number and the second supply number. The winning probability was changed, and the ratio of the number of executions of the first game and the second game was changed. However, means for changing the ratio between the first supply number and the second supply number is not limited to changing the ratio of the number of lottery executions (that is, the execution probability).

  That is, the first supply number and the second supply number are determined by the winning probabilities for winning the supply of game media in each lottery, the number of times each lottery is executed, and the number of game media supplied by one win. For this reason, the game execution means 43 performs the winning probability ratio between the first game and the second game, the ratio of the number of executions, and one winning according to the ratio between the first supply number and the second supply number. At least one of the ratios of the number of supplied game media may be changed.

  In the above embodiment, the game medium pushed out to the drop part 34 by the movable plate 32 in the pusher game part 30 is provided from the payout opening 22. However, the providing unit that provides the user with the game medium pushed to the dropping unit 34 by the movable plate 32 is not limited to the payout port 22. For example, when crediting the game medium pushed out to the drop part 34 by the movable plate 32 in the game machine 100, the control part 40 functions as a supply number.

  In this case, a fourth sensor (not shown) that detects a game medium that is pushed by the movable plate 32 and falls from the placement surface 31 to the dropping unit 34 is provided in the dropping unit 34. The counting means 46 counts the number of game media that have fallen on the dropping unit 34 based on the detection signal from the fourth sensor. The control unit 40 provides the number of game media to the user as a credit number and displays it on the display unit 10.

  Note that all the above embodiments may be combined with each other as long as they do not exclude each other. From the foregoing description, many modifications and other embodiments of the present invention are apparent to persons skilled in the art. Accordingly, the foregoing description should be construed as illustrative only and is provided for the purpose of teaching those skilled in the art the best mode of carrying out the invention. The details of the structure and / or function may be substantially changed without departing from the spirit of the invention.

  The game machine of the present invention is useful as a game machine or the like that can converge the payout rate and enhance the interest of the user.
