Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating an external configuration of a game machine according to the present embodiment. The game machine shown in FIG. 1 is configured as a medal game machine 1 that executes a pusher game. The medal game machine 1 allows a player to insert a medal into a game field inside the main body from a medal inserter 10 (described later), conveys the medal to a predetermined range using a pusher table 26 installed in the game field, and The arranged medals are paid out from a medal payout opening 13 provided on the side surface of the lower housing 2 and provided to the player.

  In a medal game machine 1 (pusher game machine) shown in FIG. 1, an upper housing 3 provided with an independent game field at four locations on a substantially cylindrical lower housing 2 is mounted. In each game field, two players can play the game. Therefore, up to eight players can play the game at the same time.

  Each game field is separated by, for example, a pillar, and the space between the pillars is covered with a transparent cover 4. As a result, the player cannot directly touch the mechanism inside the game field. Outside the transparent cover 4 in front of the game field, a game selection / decision button 12, a medal payout slot 13 and the like are provided.

  The game selection / decision button 12 is a button operated when a player gives various instructions to the medal game machine 1. For example, it is used for inputting a game selection instruction from a menu displayed on a monitor 24 (described later) or various instructions for executing a mini game.

  The medal payout slot 13 is for paying out medals to the player, and medals dropped from a lower field 20 (described later) provided in a game field in the transparent cover 4 are carried out. The medals dropped from the lower field 20 and paid out to the player are detected by the payout sensor 50d, and the CPU 39 is notified of a medal detection signal.

  For one game field formed in the upper housing 3, two medal inserters 10 (10-1, 10-2) for inserting medals into the game field are provided at right and left distances. ing.

  The medal insertion device 10 has a medal insertion port provided outside the transparent cover 4. When a player inserts a medal through the medal insertion slot, the medal passes through a medal passage that penetrates to the inside of the transparent cover 4 and is discharged from the tip. In the medal passage section, insertion sensors 50b and 50c (described later) for detecting the passage of the medals are provided, and the inserted medals are detected and the medal detection signal is output to the CPU 39 (described later). . The medal inserter 10 is mounted rotatably within a specified range so that the player can appropriately select the direction in which the medal is thrown. Thereby, the player can turn the tip of the medal passage portion of the medal inserter 10 left and right within a predetermined range, and can insert medals aiming at the checker provided in the game field. The medals inserted into the checker are detected by the checker sensor 50a, and the medal detection signal is sent to the CPU 39.

  In addition, a camera 42 that captures an image including a game object (for example, an item having a shape larger than a disk-shaped medal) movable on the game field is provided above the game field. Is arranged (not shown in FIG. 1). Details of the camera 42 and the projector 48 will be described later.

FIG. 2 is a block diagram illustrating a functional configuration of the medal game machine 1 according to the present embodiment.
As shown in FIG. 2, each part of the medal game machine 1 is controlled by the CPU 39. The CPU 39 controls each unit by executing the game program 40a stored in the memory 40. The memory 40 stores various data (such as the item management data 40b) used in executing the game, in addition to the basic program and the game program 40a.

  By executing the game program 40a, the CPU 39 realizes the functions of an item detection unit 39a, an image projection control unit 39b, an item position determination unit 39c, a time measurement unit 39d, a payout rate calculation unit 39e, and a mini game processing unit 39f. You.

  The item detection unit 39a detects an object (item) existing on the game field based on the image captured by the camera 42, and registers data corresponding to the detected object in the item management table 40b. It is assumed that the item detection unit 39a is set with object recognition data (such as pattern data) corresponding to various objects used in the game machine.

  The image projection control unit 39b projects an image set for the object onto the object (item) detected by the item detection unit 39a. The image projection control unit 39b can change an image to be projected on the object, for example, as time elapses after the object is placed on the game field, or according to the position of the object in the game field. Can be changed.

  The item position determination unit 39c determines the position of the object (item) detected by the item detection unit 39a. The item position determination unit 39c can track the object by continuously determining the position on the game field for each object registered in the item management table 40b. Thus, it is possible to determine that the object has reached (falled) the collection area. Further, since the position is determined based on the image taken by the camera 42, the tracking can be continued even if the item moves irregularly on the game field.

  The time measuring unit 39d measures, for each object, the elapsed time since the object detecting unit 39a first detects that the object (item) exists on the game field.

  The payout rate calculator 39e calculates the payout rate based on the number of medals inserted from the medal inserter 10 by the players detected by the insertion sensors 50b and 50c and the number of medals paid out to the player. Based on the payout rate calculated by the payout rate calculation unit 39e, it is possible to execute control related to an object thrown into the game field, for example, setting of an image to be projected on an item, payout control of medals, and the like. .

  The mini-game processing unit 39f controls a mini-game executed when a game situation that satisfies a predetermined condition is achieved. For example, when a predetermined number of medals are entered in the checker, a mini game is executed. In the game machine according to the present embodiment, when the mini game is executed, not only the object from the projector 48 but also the image for the mini game can be projected onto the game field.

  The CPU 39 is connected to the monitor 24, the camera 42, the speaker 43, the light source unit 44, and the button input unit 45 via the input / output control unit 41.

  The speaker 43 is housed in, for example, the lower housing 2 in FIG. 1, and outputs a sound effect at the time of game execution, BGM (back ground music), various message sounds, and the like according to the control of the CPU 39.

  The light source unit 44 controls lighting (flashing) of a light source (a lamp, an EL tube, or the like) provided in the medal game machine 1 under the control of the CPU 39.

  The button input unit 45 performs input control of buttons including the game selection / decision button 12 provided on the medal game machine 1, and outputs an input signal to the CPU 39 in accordance with an input operation performed by the player on the button.

  The CPU 39 controls the pusher base driving mechanism 46, the payout mechanism 47, the display control unit 49, and the like.

  The pusher table drive mechanism 46 reciprocates the pusher table (upper field) 26 provided in the game field in the front-rear direction at a constant cycle, for example.

  The payout mechanism 47 discharges a predetermined number of medals or items from the medal payout slot 25 under the control of the CPU 39 when a predetermined condition is satisfied. In FIG. 1, only one medal / item payout slot 25 for paying out medals or items from the upper part of the monitor 24 is shown, but medals / items for paying out medals / items to the pusher stand 26. A refund port may be provided around the pusher table 26. In this case, the payout mechanism 47 controls the discharge of medals from the medal / item payout port provided around the pusher table 26 together with the medal payout port 25.

  The display control unit 49 controls the projection of an image by the projector 48 under the control of the CPU 39 (image projection control unit 39b).

  The checker sensor 50a is a sensor for detecting that a medal has entered a slot through a checker (not shown), and outputs a detection signal to the CPU 39. When a medal enters the checker, a predetermined event is executed.

FIG. 3 is a perspective view showing a configuration around the game field in the medal game machine 1.
As shown in FIG. 3, a pusher stand 26 is provided in the game field, and the pusher stand 26 is provided with a lower field 20 and an upper field 21. The lower field 20 is used as a platform on which medals are deposited, and medals inserted from the medal inserter 10, medals dropped from the upper field 21, and medals paid out by winning are deposited. When the medals fall into the medal collection area 65 provided on the near side of the lower field 20 in the figure, medals corresponding to the number of dropped medals are discharged from the hopper to the medal payout port 13 provided on the front surface of the medal game machine 1. . Thereby, the player can acquire the medal.

  The upper field 21 reciprocates along the upper surface of the lower field 20 in the front-rear direction by a pusher table driving mechanism 46 (described later) at, for example, a constant cycle. Also, medals or items are placed on the upper field 21. When the medals on the upper field 21 fall to the near side in the drawing, they are placed on the lower field 20. When the medal falls within the reciprocating movement range on the lower field 20 when the upper field 21 is not at the foremost position during the reciprocating movement, the medal is pushed by the upper field 21 and deposited on the lower field 20. Pushed into many medals. When the medals are pushed in this way, the medals accumulated on the lower field 20 are pushed to the near side in the figure, and the medals fall into the medal collection area 65.

  A monitor 24 is installed in the front of the upper field 21 at the back. The monitor 24 displays various information (such as menus) to be presented to the player.

Further, a camera 42 and a projector 48 are arranged above the pusher table 26 (game field), as shown in FIG. The camera 42 captures an image around the game field including the pusher table 26 (the lower field 20 and the upper field 21) and the medal collecting area 65. Therefore, the camera 42 can obtain an image including a game medal and the item 60 (60a, 60b) that can be moved on the game field.
The projector 48 can project an image on the item 60 or the game field.

FIG. 4 is a diagram showing a state on the game field photographed by the camera 42.
As shown in FIG. 4, a large number of medals 62 are placed on the field of the pusher stand 26. Further, the example shown in FIG. 4 shows a state where the item 60a is placed on the upper field 21 of the pusher stand 26 and the item 60b is placed on the lower field 20. The CPU 39 determines the positions of the items 60a and 60b based on the captured images, and causes the projector 48 to project individual images on the items 60a and 60b. A projection image 61a representing the number “100” is projected on the item 60a, and a projection image 61b representing the number “41” is projected on the item 60b. The numbers projected on the items 60a and 60b indicate the number of medals paid out when the items 60a and 60b are collected in the medal collection area 65. The CPU 39 changes the projection images 61a and 61b projected on the items 60a and 60b, for example, so that the numbers become smaller as time passes.

FIG. 5 is a diagram illustrating an example of data managed in the item management table 40b.
As shown in FIG. 5, a unique item identifier is set in the item management table 40b for each item placed on the game field. Then, in association with the item identifier, for each item, elapsed time data after being placed on the game field, projection image data (for example, an image file) indicating an image projected from the projector 48 on the item, a projection image The payout medal number data indicating the payout medal number corresponding to the data, the position data indicating the position of the item on the game field, and the like are set.

Next, an operation of the medal game machine 1 in the present embodiment will be described with reference to flowcharts shown in FIGS.
FIG. 6 is a flowchart showing a game control process (overall process) by the medal game machine 1.
When the game is started, the CPU 39 starts capturing an image on the game field (the pusher stand 26) by the camera 42 (step A1). The item detection unit 39a executes an item detection process for detecting an item existing in the game field based on the image captured by the camera 42 (Step A2).

FIG. 7 is a flowchart illustrating details of the item detection process.
The item detection unit 39a searches for an item 60 from an image captured by the camera 42 (Step B1). When searching for the item 60 by data for item recognition used in the medal game machine 1, for example, pattern matching, the item detection unit 39a determines whether an object present in the image is an item based on the pattern data of the item. Is determined. Note that a search method other than pattern matching can be used for searching for the item 60.

  Here, if no item is detected, the item detection processing ends. On the other hand, when an item can be detected from the image, the item position determination unit 39c determines the position of the detected item on the game field, and determines whether the item has been registered in the item management table 40b. For example, the item position determining unit 39c determines that the position of the detected item on the game field is close to the position of the item registered in the item management table 40b (if it is within a preset reference value). Determines that the item is a registered item (step B2, Yes). If the position is not close to the position of the registered item, the item position determination unit 39c determines that the item is a new item detected by being newly paid out from the medal / item payout opening 25 ( (Step B2, No), a new item identifier is registered in the item management table 40b (Step B3).

  The item detection unit 39a determines whether all the items registered in the item management table 40b have been searched (step B4). If all registered items have been searched (step B5, Yes), the item detection process ends. On the other hand, if there is an item that has not been searched for (step B5, No), this item is set as a fallen item that has fallen into the medal collection area 65 and deleted from the item management table 40b (step B6).

  Thus, in the item detection processing, the items registered in the item management table 40b can be continuously tracked. In the item detection processing, it is possible to detect that an item has dropped into the medal collection area 65 from an image captured by the camera 42. Therefore, the game machine does not need to be provided with a sensor or the like for detecting the item, and the shape of the item used in the game machine is not restricted.

  In addition, in order to identify a plurality of items 60 and to facilitate a process of individually following the items 60, identification information such as a unique mark or color may be added to each of the items 60. In this case, the item detection unit 39a detects the identification information added to the item 60 from the image captured by the camera 42, and detects and follows each item 60 based on the identification information.

  Next, when an item is detected in the item detection process (Step A3, Yes), the image projection control unit 39b executes an image projection control process for projecting an image on the item (Step A4). .

FIG. 8 is a flowchart illustrating details of the image projection control process.
If not all the items detected by the item detection processing have been registered, that is, if there is an item newly registered in the item management table 40b (step C1, Yes), the image projection control unit 39b determines whether the item has been registered. An initial projection image to be projected on the newly registered item is set according to the current payout rate calculated by the payout rate calculation unit 39e.

  In the medal game machine 1 according to the present embodiment, an image of a number representing the number of medals paid out when the item 60 is dropped into the medal collecting area 65 is projected on the item 60. The image projection control unit 39b compares the current payout rate with a plurality of reference values for determining a predetermined initial projection image, and determines which set range the current payout rate is included in. I do. Then, the image projection control unit 39b sets an image for projecting a number corresponding to the set range including the current payout rate as an initial projection image, and sets the number corresponding to the set range as payout medal number data as an item. Set in the management table 40b.

  For example, when the current payout rate is included in the set range in which the payout of medals is determined to be the least, an image for projecting “100” representing the maximum payout number is set. As a result, the number of payout medals is easily increased. Conversely, if the payout of medals is large, an image for projecting a small number indicating that the number of payouts is small, for example, “50” is set.

  In addition, the time measuring unit 39d measures the elapsed time from being placed on the pusher table 26 (game field) for each item registered in the item management table 40b, and outputs elapsed time data indicating the elapsed time. It is set in association with each item identifier registered in the item management table 40b (step C3).

  The image projection control unit 39b refers to the elapsed time data set in the item management table 40b and sets a projection image (number) according to the elapsed time measured for each item (step C5). Here, for example, the projection image is set so that the value of the numeral is reduced every time a predetermined time period elapses. Further, the payout medal number data of the item management table 40b is changed in accordance with the change of the projection image (number).

  When the projection image is set for each item in this way, the image projection control unit 39b projects an image on each item 60 according to the position of each item 60 determined by the item position determination unit 39c (Step C6). .

  For example, in the example shown in FIG. 4, a projection image 61a representing the initial value “100” is projected on the item 60a, and the item 60b is first paid out to the game field. The number decreases in accordance with the elapsed time of, and a projection image 61a representing the number “41” is projected.

  Further, when time elapses from the state shown in FIG. 4, for example, as shown in FIG. 10, the projected images 61a and 61b for the items 60a and 60b are changed. As shown in FIG. 10, projection images 61a and 61b indicating the number “89” for the item 60a and the number “29” for the item 60b are respectively projected.

  In this way, by changing the image projected on the item 60 over time, for example, an effect using the item 60 can be realized. The player sees the image (number) projected on the item 60, and can aim the item 60 to be dropped into the medal collection area 65.

  In the above description, the payout rate is used when setting the initial projected image for the item 60, but may be used when changing the image (number) to be projected on the item 60. For example, the value range to be decreased every time a certain time elapses is changed according to the payout rate. For example, if the payout rate indicates a situation in which the payout of medals is large, the value range to be reduced every time a certain time elapses is increased to reduce the payout of medals.

  In addition, not only the projection image is changed with the passage of time, but also the projection image may be set or changed according to the position of the item 60 determined by the item position determination unit 39c. For example, an initial projection image (number) can be set according to whether the first placed position is the upper field 21 or the lower field 20. Further, the image projected on the item 60 can be changed depending on whether the item 60 is located near the center in the width direction of the game field or near both sides of the game field. For example, it is more difficult for the item 60 near the center to drop into the medal collection area 65 than the item 60 near both sides, so that the value range to be reduced with time is reduced for the item 60 near both sides. Smaller than for 60.

  When the image projection control process is completed, the CPU 39 determines whether the item 60 has fallen into the medal collection area 65 in the item detection process (step A5, Yes). A number of medals according to the set number are paid out (step A6). That is, the CPU 39 refers to the payout medal number data set in the item management table 40b in association with the item identifier of the item determined to have fallen, and determines the number of medals corresponding to the payout medal number data to the player ( The payout is made to the medal payout slot 13).

  For example, as illustrated in FIG. 11, when it is determined that the item 60b has dropped into the medal collection area 65, the CPU 39 determines that the item 60b has dropped and associates the item 60b with the item identifier of the item 60b. The number of medals according to the payout medal number data set in the table 40b is paid out.

  In addition, the payout rate calculation unit 39e calculates the number of medals paid out to the player, including the number of medals terminated by the player detected by the insertion sensors 50b and 50c and the number of medals detected by the payout sensor 50d. The payout rate is calculated based on the number of copies. The payout rate calculated by the payout rate calculation unit 39e is referred to in the above-described image projection processing.

  Thus, the positions of the items 60a and 60b existing on the game field can be detected based on the images captured by the camera 42, and the images set for the respective items can be projected from the projector 48.

  The mini-game processing unit 39f monitors whether or not the game situation satisfies a predetermined condition for executing the mini-game. For example, when it is determined from the medal detection signal from the checker sensor 50a that a medal has been inserted into the checker, the mini game processing unit 39f determines that the game situation is such that the mini game is to be executed, and executes the mini game. Start. Note that the predetermined condition for executing the mini game can be arbitrarily set.

FIG. 9 is a flowchart showing details of the mini game process.
First, the mini game processing unit 39f causes the image projection control unit 39b to project an image for executing a mini game onto the game field (step D1).

  FIG. 12 shows an example of the situation of the game field when the mini game is executed. In the example shown in FIG. 12, a target line A representing the target of the destination of the items 60a and 60b and arrows B1 and B2 indicating the directions of the items 60a and 60b with respect to the target line A are projected. The position where the target line A is projected may be determined in advance, or may be set, for example, at a position where the target line A can be easily reached according to the current items 60a and 60b.

  The mini game processing unit 39f determines whether the items 60a and 60b have reached the target line A during the execution of the mini game based on the positions of the items 60a and 60b determined by the item position determination unit 39c. When it is determined that the items 60a and 60b have reached the target line A (Step D2, Yes), the mini game processing unit 39f sends the medals of the number corresponding to the items 60a and 60b to the player (the medal payout port 13). ). For example, the payout medal number data set for the item 60 that has reached the target line A can be referred to and payout medals of twice the number of payout medals can be paid out.

  Note that the mini game shown in FIGS. 9 and 12 is an example, and the game content can be arbitrarily set. In the medal game machine 1 according to the present embodiment, the projector 48 projects a specific image not only on the items 60a and 60b but also on a game field other than the items 60a and 60b, thereby minimizing the player. Provide games.

  For example, as shown in FIG. 13, a projection image 62 for staging (buzzing) can be projected on the entire game field irrespective of the items 60a and 60b. Further, according to the contents of the mini game, images such as the target lines A and A2 and the arrow B3 can be projected, and an image 63 for a message to the user can be projected. In FIG. 13, for example, “Get a bonus medal if you drop a medal in this area!” Is displayed as the message image 63. In this way, not only the position of the item, but also an image for an effect or a message can be projected at an arbitrary position on the game field according to the game situation.

  In this manner, in the medal game machine 1 according to the present embodiment, the game situation is grasped using the image captured by the camera 42, and an arbitrary image is projected from the projector 48 onto the game field according to the game situation. Because of this, various effects can be realized. In addition, since it is not necessary to add a special configuration (display device or the like) for performing various effects, the manufacturing cost of the game machine does not increase.

  In the above description, as shown in FIG. 3, one camera 42 and one projector 48 are provided for one game field, however, the camera 42 and the projector 48 are shared in a plurality of game fields. It is good also as a structure which performs.

  FIG. 14 shows an example in which four pusher stands 26a, 26b, 26c, 26d are installed. In the example shown in FIG. 14, the pusher tables 26a and 26b and the pusher tables 26c and 26d are respectively arranged adjacent to each other, and the rear surfaces of the pusher tables 26a and 26b and the pusher tables 26c and 26d (the back sides of the monitor 24) face each other. I have to. The camera 42 and the projector 48 are arranged above the four pusher stands 26a, 26b, 26c, 26d.

  As shown in FIG. 15, the projection range 80 of the projector 48 and the camera viewing range 82 of the camera 42 include all of the game fields of the four pusher stands 26a, 26b, 26c, 26d. In this way, the game can be executed while projecting images on the plurality of pusher stands 26 by installing only one camera 42 and one projector 48, respectively.

  Also, as shown in FIG. 14 and FIG. 15, instead of directly projecting an image on the game field from the projector 48, a mirror is installed above the game field as shown in FIG. 16 and FIG. It is also possible to configure so that an image can be projected onto the entire game field of a plurality of pusher stands 26 via a mirror.

  FIG. 16 shows a mirror in which four pusher stands 26 a, 26 b, 26 c, and 26 d are installed so that the backs of the monitors 24 face each other so as to form a cross, and a projector 48 is arranged above the pusher stand 26. Is shown.

  For example, two mirrors 91a and 92a are arranged above the game field with respect to the pusher table 26a. As shown in FIG. 17, the image from the projector 48 is projected on the game field of the pusher stand 26a via the mirrors 92a and 91a.

  In addition, similarly to the pusher table 26a, two mirrors are arranged for each of the pusher tables 26b, 26c, and 26d as shown in FIGS. 16 and 17, and an image from the projector 48 is transmitted through the mirror. Projected.

  In this case, different images are projected individually according to each item (or game situation) detected from the image of the game field of each of the pusher tables 26a to 26d.

  FIG. 18 shows an example of images 95a, 95b, 95c, and 95d projected from the projector 48 onto the pusher tables 26a to 26d. The images 95a, 95b, 95c, and 95d are images projected onto the pusher tables 26a to 26d, respectively, and different images according to the state of the board of the pusher tables 26a to 26d are projected.

  Note that the camera 42 may be provided for each game field, or may be shared in a plurality of game fields, similarly to the projector 48.

  In this way, by arranging the mirror inside the housing and projecting the image from the projector 48 via the mirror, the focal length from the lens of the projector 48 to the board surface is extended to cover a wide area. Can be projected. In addition, even if it is necessary to arrange a jack pod mechanism or a structure on the design in the housing, the image from the projector 48 is projected onto the board surface by projecting the image through the mirror so as to avoid the structure. can do.

  In the above description, an image representing a number is projected on the item 60, but the image projected on the item 60 can be arbitrarily adopted. For example, a pattern or a mark may be used, or the color of an image to be projected may be changed. Further, although the shape of the item 60 is a disk shape, an item of any shape can be used. For example, it may be a square or star-shaped flat item, or a three-dimensional item such as a sphere or dice. Since the detection of the position of the item and the drop to the medal collecting area 65 are performed based on the image captured by the camera 42, even if the shape of the item used in the game is changed, the sensor mounted on the medal game machine 1 is used. There is no need to change the settings, and it suffices to respond to the image processing (program) for item detection by the item detection unit 39a.

  In the above description, the item 60 is detected from the image captured by the camera 42. However, the game situation may be determined by detecting an object other than the item 60, for example, a medal.

  Further, in the above description, the pusher game machine (medal game machine 1) is described, but it is also possible to cover another game machine that moves an object on a game field. For example, a puzzle game or the like in which the arrangement of a plurality of panels (objects) is correctly combined can be realized.

  FIG. 19 shows an example of a game machine that executes a puzzle game. FIG. 19 shows only a base 70 disposed on the game field, a block 71 movably mounted on the base 70, and a camera 42 and a projector 48 disposed above the game field (base 70). ing. The other configuration is substantially the same as that shown in FIG. 2 and the detailed description is omitted.

  The base 70 arranged on the game field has a square shape, and eight blocks 71 having the same square shape are placed thereon. The position of the block 71 can be arbitrarily changed to an empty space for one block by an operation of the player. The position of each block 71 is determined based on an image captured by the camera 42, and an individual image is projected on each block 71 by the projector 48. For example, as shown in FIG. 20, a fixed image corresponding to a part of one picture determined for each block is projected on each block 71.

  When the puzzle game is started, the player directly moves the block 73 using the hand 74 as shown in FIG. The CPU 39 recognizes the position of the block 73 based on the image captured by the camera 42, and changes the projection position of the image projected on the block 73 from the projector 48 in accordance with the movement of the block 73.

  When the CPU 39 detects that the block 71 has been moved to a predetermined position by the operation of the player and the pattern has been completed as shown in FIG. 22, the CPU 39 determines that the game has been cleared.

  In the above-described puzzle game, individual images are projected on the blocks 71. However, game contents such as increasing the degree of difficulty by changing the images to be projected according to the moving position of the blocks 71 and the passage of time. Can be changed. Also, the pattern can be freely changed only by changing the image projected from the projector 48.

  In the game machine according to the present embodiment, since an image can be projected on an object by the projector 48, a variety of game contents can be provided without the need to replace the object itself.

  In the game machine according to the present embodiment, the position of each object (block, panel, etc.) is detected based on the image captured by the camera 42, and the image is individually projected on the object. Therefore, the game machine according to the present embodiment can be applied to various games in which the game object can be moved on the game field, in addition to the medal game machine 1 and the puzzle game, and various games using the object can be used. Direction can be realized.

  Further, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying constituent elements in an implementation stage without departing from the scope of the invention. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the above embodiments. For example, some components may be deleted from all the components shown in the embodiment. Further, components of different embodiments may be appropriately combined.
