DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball-and-ball game machine, and more particularly, to a degree of expectation of occurrence of a big hit when a variation mode of a first symbol is displayed in at least a reach mode by a display mode of a second symbol. Related to the effect display.

[0002]

2. Description of the Related Art Conventionally, in a ball-and-ball game machine such as a pachinko machine, a game board is provided with a symbol starting means, a symbol display means, a variable winning means (opening / closing type winning means) called an attacker, etc. When a plurality of special game symbols of the symbol display means fluctuate for a predetermined fluctuation time on condition that a ball is detected, and the stop symbol after the fluctuation displays a specific symbol mode (so-called jackpot symbol mode), The variable winning means repeats the opening and closing operation up to a set number of times based on predetermined conditions,
A special game state advantageous to the player occurs.

[0003] Further, in the symbol display means of this kind of pachinko machine, when the reach mode is determined by two special game symbols, when a large number of characters such as fish which are not normally displayed are produced and displayed as a background image by animation. There is. In this case, the expectation (reliability) of the jackpot is very high, for example, about 40 to 50%. When such a large number of characters are produced and displayed, a jackpot occurs. The player's expectation that this is not the case will be maximized, and the effect of the effect display can be achieved.

[0004]

However, in this type of ball game machine, regarding the jackpot expectation degree, the background character has no relation to the special symbol, which is one of the factors that impair the interest of the player. Has become.

[0005] It is an object of the present invention to improve the amusement of a player by enabling a background character to be directed and displayed in relation to a special symbol with respect to the degree of expectation of a jackpot in a reach mode. And so on.

[0006]

[Means for Solving the Problems] The ball game machine of the present application
A game ball detecting means for detecting a game ball, and a plurality of first symbols are variably displayed on condition that the game sphere is detected by the game ball detection means, and a plurality of first symbols are displayed in a predetermined variation display mode. A symbol display means for displaying a second symbol for a background effect, and a profit for generating a profit state advantageous to the player on condition that a combination of the first symbol when changing and then stopping is in a specific mode. In the ball game machine provided with the state generating means, when the variation mode of the plurality of first symbols is at least the reach mode, the second symbol of the same type as the first symbol is displayed, and the display mode of the second symbol is displayed. And a degree of occurrence expectation that a profit state is generated by the profit state generating means.

[0007] When the reach mode is set after a plurality of first symbols are variably displayed, a second symbol of the same type as the first symbol is displayed for production. In this case, since the display mode of the second symbol is related to the expected degree of occurrence of the profit state, the player can estimate the magnitude of the expected level of occurrence by the display mode of the effect-displayed second symbol. You can enjoy the game.

By the way, in the ball game machine provided with the same game ball detecting means, symbol display means and profit state generating means as described above, when the variation mode of the plurality of first symbols is at least the reach mode, You may comprise so that the combination of a 1st symbol and a 2nd symbol and the expectation degree which a profit state generate | occur | produces by a profit state generation means may be related. Again, in this case,
Since the combination of the first symbol and the second symbol is related to the expected degree of occurrence of the profit state, the player can enjoy the game, for example, by estimating the magnitude of the expected degree of occurrence.

Here, the plurality of first symbols are each composed of a numeral symbol and a first symbol, and the plurality of second symbols are respectively a plurality of second symbols of the same type as any one of the plurality of first symbols. The number of second symbols of the same type as the first symbol of the first symbol constituting the reach mode may be associated with the expected degree of occurrence. Further, the configuration may be such that the larger the number of the second patterns, the higher the expected degree of occurrence. Further, it may be configured such that the closer the number of the second symbols is to the number indicated by the numeral symbol of the first symbol constituting the reach mode, the higher the expected degree of occurrence is.

It controls the lighting of a lamp group 72 including lamps and the like. The sound control means 73 provided on the sound control board 43 receives a sound control command from the main control means 50 and controls sound output for various sound effects to a speaker 74 provided on the back side of the ball tray 8. Govern The launch control means 75 configured on the launch control board 48 drives the launch motor 13 and controls launch of the game ball.

The main control means 50 includes lottery means 51 for determining whether or not to generate a profit state, determination means 52, profit state generation means 53, symbol determination means 55, command transmission means 56, and the like. ing. The lottery means 51 uses a lottery counter to set a lottery value in a predetermined range (for example, 0 to 299) in a minute update cycle (for example, about 2 msec cycle).
With respect to the special game symbol, a numerical value when the game ball has won the symbol starting means 17 is extracted. Lottery means 51
Extracts a numerical value when a game ball passes through the operation port 20 for a normal game symbol. That is, the lottery means 51
Performs a lottery in accordance with a game operation, that is, a game mode or a behavior of a game ball.

The judging means 52 determines the "big hit" for the special game symbol based on the numerical value extracted by the lottery means 51 when the game ball has won the symbol starting means 17 or the operating port 20.
Or "out (including out of reach)", and also "hit" for normal game symbols.
Alternatively, it is determined which of “missing”. Further, the determination means 52 also performs determination with respect to the probability variation type jackpot,
If it is determined that the probability is changed, the number of the specific numerical values to be the big hit is increased from the normal time until the next or subsequent big hits or until the special game symbol fluctuates a predetermined number of times. In addition, in the case of such a probability fluctuation, the determination unit 52 instructs the profit state generation unit 53 described later to give a predetermined profit.

The profit state generating means 53 receives the judgment result of the big hit from the judging means 52, or the predetermined pattern included in the game control on condition that the stopped symbol after the change of the special symbol display means 22 becomes the big hit symbol. The opening / closing plate 18a of the variable winning means 18 is opened / closed as described above by the profit state generating routine. Further, the profit state generating means 53
When the above-mentioned probability variation instruction is received from the determination means 52, the opening and closing claw 17a of the symbol starting means 17 is opened for a longer time than usual, on condition that the normal game symbol 23 becomes "hit". Then, a profit state is provided such that the game balls can easily enter.

The symbol determining means 55 determines a normal game symbol and a normal symbol variation pattern by a predetermined lottery program according to the determination result from the determining means 52, based on a predetermined lottery program. At the same time, in the case of "missing", a normal game symbol and a normal symbol variation pattern are determined by lottery. The symbol determination means 55 further relates to a special game symbol and an effect display.
In the case of "big hit", the special game symbol and the special symbol change pattern of the big hit are determined, and in the case of "miss", the special game symbol and the special symbol change pattern of the miss are determined.

The command transmitting means 56 is a symbol determining means 5
Based on the fluctuation pattern determined in step 5, the symbol control means 60 transmits a fluctuation pattern designating code for designating a fluctuation pattern for a normal game symbol or a special game symbol, a stop symbol, and a fluctuation stop command. Not only is the transmission output for each change, but also the payout control means 70 and the ramp control means 71
Then, various control commands associated with the symbol change are transmitted to the sound control means 73 and the like as necessary.

The symbol control means 60 includes the ordinary symbol display means 2
3, a special symbol control means 61 for controlling the special symbol display means 22, a special symbol control means 62 for controlling the special symbol display means 22, a variable pattern storage means 63, etc., for receiving a symbol control command transmitted from the command transmission means 56. Then, the received symbol control command is analyzed. The ordinary symbol control means 61 controls the ordinary symbol fluctuation in each of the symbol display sections 23a and 23b, and the special symbol control section 62 controls the special symbol fluctuation in each of the symbol display sections 22a to 22c. In the variation pattern storage unit 63, the operation contents (including the variation time) of the normal game symbol and the special game symbol are stored in association with each of the plurality of variation pattern numbers.

It is assumed that the fluctuation pattern storage means 63 further stores pattern information of a number of effect patterns to be effected and displayed by various characters and backgrounds. Here, a description will be given of a plurality of special game symbols (corresponding to a first symbol) displayed on each of the symbol display portions 22a to 22c. The plurality of special game symbols are respectively a numeric symbol and a first symbol. Consists of

That is, for example, one special game symbol includes a numeral symbol “1” and a first symbol “jellyfish” (not shown), and one special game symbol includes a numeral symbol “2” and a first symbol. As shown in FIG. 7, one special game symbol T3 includes a numeral symbol "3" and a sea urchin U1 (this corresponds to a first symbol), as shown in FIG. Further, one special game symbol includes a numeral symbol “4” and a first symbol “clam”. However, the sea urchin U1
Are colored "red".

Next, a description will be given of a background effect pattern which is effect-displayed when the change display mode of the special game symbol variably displayed on the symbol display sections 22a to 22c is the reach mode. Here, sea urchin U1 of one special game design T3
The same kind of sea urchin group U2 (this corresponds to the second symbol)
A description will be given of a background effect pattern relating to FIG. However, the sea urchin group U2 includes a plurality of “red sea urchins” U2.
r and a plurality of “white sea urchins” U2w.

Here, these red sea urchin U2r and white sea urchin U2
w corresponds to the second picture. That is, the sea urchin group U2 is composed of six sea urchins in this example by adding the red sea urchin U2r and the white sea urchin U2w, and the red sea urchin U2r and the white sea urchin U2w in the case of the hit and the case of the miss. And the number of background effect patterns are respectively set as shown in the figure.

The plurality of background effect patterns included for each pattern number are designed so that the background effect display is not monotonous, for example, by changing the positional relationship and the moving speed of the plurality of sea urchins. In this case, as the effect pattern for the background, although not shown, in addition to the special game pattern T3 shown in FIG. 6, the first patterns “jellyfish”, “squid”, “clam”, etc. of a plurality of other special game patterns are provided. Are set for each of the jellyfish group, the squid group, and the clam group with respect to the second pattern “jellyfish”, “squid”, and “clam”, which are the same as each other. That is, the plurality of second symbols of the sea urchin group U2 and the like each include a plurality of second symbols of the same type as any one of the plurality of types of special game symbols.

Therefore, as shown in FIG. 7, during the symbol change, the reach mode in which two special sea urchin special game symbols T3 are stopped and displayed on the two symbol display portions 22a and 22c, respectively (this is a variable display mode). Next, the degree of expectation of occurrence of a jackpot in the case of (equivalent to) will be described.

That is, when the pattern number "1" is selected by lottery and only "6" red sea urchins U2r are displayed as the sea urchin group U2, the expected degree of occurrence is 100%.
(2 / (the number of patterns per hit “2” + the number of out-of-patterns “0”). When the pattern number “2” is selected, there are “5” red sea urchins U2r and white sea urchins U2w)
Is 90% (10 / (the number of patterns per unit "1") when the sea urchin group U2 including "1" is displayed.
0 "+ the number of out-of-order patterns" 1 ").

When the pattern number "3" is selected and the sea urchin group U2 composed of "4" red sea urchins U2r and "2" white sea urchins U2w is displayed, the expected degree of occurrence is as follows. , 81% (9 / (the number of patterns per hit “9” + the number of out-of-patterns “2”). Similarly, when the pattern number “6” is selected by lottery, the red sea urchin U2r becomes “ When the sea urchin group U2 including “1” and the white sea urchin U2w including “5” is displayed, the expected degree of occurrence is 54%.
(6 / (the number of patterns per hit “6” + the number of out-of-patterns “5”).

As described above, when the reach mode is set as the variation mode of the special game symbol T3, the same type of sea urchin group U2 as the special game symbol T3 is displayed, and the sea urchin group U2 is displayed based on the background effect pattern data. The display mode and the expected degree of occurrence of the profit state generated by the profit state generating means 53 are associated with each other. Here, the profit state generating means 53 is constituted by a microcomputer provided in the main control means 50 and a profit state generation control program stored in the ROM, and the symbol control means 60 and the display means (the liquid crystal display 16) 21 and the like display symbols. Means are configured.

Next, the pachinko machine 2 configured as described above
The operation of will be described. The player operates the firing handle 11 to fire the game balls sequentially sent from the ball tray 8 to the game area 5 a of the game board 5. And game board 5
When the game balls falling along the line win the symbol starting means 17 or the normal winning means 19, the payout means 35 is operated, and the number of game balls corresponding to the winning type is paid out to the ball tray 8. Here, when the game ball wins the symbol starting means 17, the lottery means 51 extracts the value for the jackpot determination, and the special game symbols are changed in each of the symbol display portions 22a to 22c.

When the reach mode is determined by the lottery, while the symbol fluctuating for a predetermined time fluctuates in the course of the symbol change, as shown in FIG.
As shown in FIG. 7, when the reach mode is such that the red "sea urchin" special game symbol T3 is displayed on the two symbol display units 22a and 22c, as described above, the "uni sea urchin" U1 of the special game symbol T3 is displayed. One background effect pattern is selected by lottery from among the background effect patterns (see FIG. 6) relating to the same type of sea urchin group U2, and the occurrence expectation at which a big hit occurs is determined at the same time. In this case, for example, the pattern number “5”
Is selected, "63%" is required as the expected degree of occurrence.

Then, the liquid crystal display 16 includes
As shown in the figure, there are two red sea urchins U2r and white sea urchins U2r.
The sea urchin group U2 in which 2w is “4” is displayed. In this case, the plurality of red sea urchins U2r and the plurality of white sea urchins U2w
Are displayed as a group, and are directed to move the display screen from right to left. Therefore, the expected occurrence degree is approximately “60”.
% ". By the way, when the reach mode is determined in the fluctuation of the special game symbol after the next time, for example, since the pattern number “3” is selected, “81%” is obtained as the occurrence expectation degree.

Then, the liquid crystal display 16 has
As shown in the figure, the number of red sea urchins U2r is "4"
The sea urchin group U2 in which 2w is “2” is displayed. Also in this case, the plurality of red sea urchins U2r and the plurality of white sea urchins U2r
2w is a group, and is rendered and displayed so as to move the display screen from right to left. Therefore, it can be seen that the expected degree of occurrence is very high, about “80%”.

As described above, the two symbol display portions 22a, 22
In the reach mode in which the red sea urchin special game symbol T3 is stopped and displayed in 2c, a sea urchin group U2 of the same kind as the red sea urchin is rendered and displayed on the liquid crystal display 16, and further, the rendered sea urchin group U2 is rendered. In, red sea urchin U
The greater the number of 2r's, the higher the degree of expectation that a profit state will occur. That is, since the display mode of the sea urchin group U2 is related to the expected degree of occurrence of the profit state, the player can estimate the degree of expectation for the jackpot based on the display mode of the stunned sea urchin group U2. Therefore, the interest of the player can be improved.

A modification of the above embodiment will be described. 1) Sea urchin group U2 of the same kind as red sea urchin U1 of special game design T3
For example, as shown in FIG. 9, a pattern of a sea urchin group U2 composed of “3” red sea urchins U2r and “3” “white sea urchins” U2w set as pattern numbers “3” as shown in FIG. The largest number is provided, and the occurrence expectation in this case is as high as “90%”.
In the background effect patterns of pattern numbers 1, 2, 4, and 5 in which the number of r is set to a value other than “3” (1, 2, 4, 5), the expected degree of occurrence is small.

In this case, when the pattern number "1" is selected, "5" red sea urchins U2r and "1" white sea urchin U2w are displayed as shown in FIG. Since the number “5” of the red sea urchin U2r in the sea urchin group U2 is not close to the number “3” indicated by the numeral symbol of the special game symbol T3 constituting the reach mode, the expected occurrence rate is low as “63%”. .

However, when the pattern number "3" is selected, as shown in FIG. 11, the red sea urchin U2r becomes "3".
And three white sea urchins U2w are displayed, the number “3” of the sea urchin group U2 is the same as the number “3” indicated by the numeral symbol of the special game symbol T3 in the reach mode, and therefore, the occurrence expectation The degree is as high as “90%”.

As described above, the two symbol display sections 22a, 2
In the reach mode in which the red sea urchin special game symbol T3 is stopped and displayed in 2c, a sea urchin group U2 of the same kind as the red sea urchin is rendered and displayed on the liquid crystal display 16, and further, the rendered sea urchin group U2 is rendered. In the sea urchin group U
The closer the number of red sea urchins U2r in 2 is to the number “3” indicated by the numeral symbol of the special game symbol T3 constituting the reach mode,
The expectation of the occurrence of the profit state is high.

That is, since the display mode of the sea urchin group U2 is related to the expected degree of the occurrence of the profit state, the player can expect the jackpot, that is, the profit state to be generated, by the display mode of the sea urchin group U2 in the background effect. The degree can be estimated.
Therefore, the interest of the player can be improved. 2] In the effect display by the sea urchin group U2 in FIGS. 7 and 10, all are initially displayed as white sea urchins, and then colored "red" by the number of red sea urchins U2r defined by the selected background effect pattern. It may be displayed.

3) The number of sea urchins constituting the sea urchin group U2 produced in the background effect shown in FIG. 7 and FIG. 10 is not limited to six, and more sea urchins may be displayed. Alternatively, the larger the proportion of the red sea urchin U2r in the total number of sea urchins, the higher the expected degree of occurrence of the profit state may be set. 4) The sea urchin group U2 produced in the background may be composed of a plurality of types of sea urchins having different sizes, and the larger the displayed sea urchin, the higher the expected degree of occurrence of the profit state may be set. In addition, the larger the number of the large sea urchins displayed, the higher the expected degree of occurrence may be set.

5] When the background is produced by the sea urchin group U2,
The higher the number of sea urchins remaining without moving, the higher the expected degree of profit state occurrence may be set. 6] The combination of the special game symbol (first symbol) and the sea urchin group U2 (second symbol) constituting the reach mode may be configured so that the expected degree of occurrence of the profit state can be estimated. 7) The present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the spirit of the present invention. Further, the present invention is not limited to pachinko machines, and may include various types of gaming balls and coins. The present invention can be applied to various ball game machines such as an arrangement ball machine and a sparrow ball game machine using a game medium.

[0054]

According to the invention of the present application, when a plurality of first symbols are in the reach mode, the second symbols of the same type as the first symbols are provided.
Since the symbol is displayed for the effect, and the display mode of the effect-displayed second symbol is related to the expected degree of occurrence of the profit state, the degree of expectation for the jackpot in the case of the reach mode is used for the background. The effect display of the character in association with the special symbol can improve the interest of the player.
