[Prior art]
  Conventionally, in a ball game machine such as the first type of pachinko machine, in addition to the normal winning means, a normal symbol start is added to the game board.MovementMeans (so-called gate means), special symbol starting means (so-called electric tulip), normal symbol display means capable of variably displaying one or more ordinary symbols, special symbol display means capable of variably displaying a plurality of special symbols, In addition, when a game ball launched into the game area of the game board by the launching means wins the special symbol starting means, a plurality of special symbol display means is provided. The special symbol fluctuates for a predetermined fluctuation time.
[0003]
At this time, if the result of the lottery at the time of winning the special symbol starting means of the game ball is a big win, the stop symbol after the change becomes a specific symbol mode (a so-called “777” or other big hit symbol mode) and a big prize is won. The mouth means repeats the opening / closing operation up to a set number of times (for example, 16 rounds) based on a predetermined condition, and a special game that is in a profit state advantageous to the player is generated. In this case, a plurality of game balls can be won while the special winning opening means is opened, and a great profit is returned to the player.
[0004]
By the way, in this kind of ball game machine, when the special symbol becomes a big hit or a reach symbol, the display means performs an effect display by a special character that is not normally displayed, A number of effect lamps provided on the board and front frame blink at high speed, and various kinds of sounds are output, so that the effect of the effect is enhanced, so that the player's ball game is excited. Yes.
[0005]
Recently, when a jackpot or super reach is drawn, a background display command is transmitted from the game control means (so-called main control means) for performing game control on the game board side to the symbol control means. There is also a practical application of effect display such as switching to the symbol background indicated by the received background display command and displaying it in advance.

The payout control means 100 configured on the payout control board 45 receives a payout control command from the main control means 50 and controls payout of game balls by the payout / ball lending means 35.
[0034]
Incidentally, an external interface board 48 is further accommodated inside the board case 43, and an external interface means 105 is formed on the external interface board 48. The launch control means 106 configured on the launch control board 47 controls the launch of the game ball by driving the launch motor 13. Here, from the external output board 32, the number of fluctuations related to the special symbol, information on the stop symbol, and the like are transmitted and output to an island computer (not shown) provided in the pachinko hall.
[0035]
The main control means 50 includes a random number generation means 51, an extraction means 52, a holding means 53, a determination means 54, and a design fluctuation determining means 55, which are both special symbols and ordinary symbols, and a probability changing means 56, A normal profit state generating means 57, a special profit state generating means 58, a command transmitting / receiving means 59, a winning counting means 60, and the like are provided. Here, the random number generation means 51, the extraction means 52, the determination means 54, and the like constitute lottery means for normal symbols and special symbols, respectively.
[0036]
The random number generating means 51 repeatedly generates control random numbers up to, for example, “0-9” for normal symbols at a predetermined minute update cycle (for example, about 2 msec), and for example, “0-299” for special symbols. Control random numbers up to "are repeatedly generated. Among the plurality of control random numbers from “0 to 9” generated by the random number generation means 51, “0 to 8” is set as a hit determination symbol that is a predetermined specific random number. Also, only one control random number (for example, “17”) among a plurality of control random numbers from “0 to 299” generated by the random number generation means 51 is set as a jackpot determination symbol that is a predetermined specific random number. Has been.
[0037]
The extracting means 52 extracts one control random number when the game ball passes through the normal symbol starting means 18 on either the left or right side of the plurality of control random numbers generated cyclically by the random number generating means 51. For the special symbol, one control random number when the game ball wins the special symbol starting means 20 is extracted. The holding means 53 can store up to 4 control random numbers for normal symbols and special design random numbers from the extracting means 52, and can hold them, and the pending control random numbers can be stored in first-in first-out (First In First Out) is supplied to the judging means 54.
[0038]
Whether the determination means 54 is a “random” or “excluded” match with the specific random number at the time before the change of the normal symbol, regarding the control random number for the normal symbol supplied from the holding unit 53 Determine. The determination unit 54 further determines whether the control random number for the special symbol supplied from the holding unit 53 is a “big hit” that matches the specific random number before the change of the special symbol, Including) ”.
[0039]
Further, the determination means 54 also determines the probability variation type jackpot for the control random number for the special symbol, and if it is determined to be the probability variation type, after the special game in the profit state has ended. Until the next or next big hit, or until the special symbol fluctuates a predetermined number of times (for example, 100 times), the number of specific random numbers to be jackpots is set to the probability changing means 56 via the special profit state generating means 58. It is commanded to increase the probability of jackpot higher than normal by increasing the normal number.
[0040]
As described above, when the probability variation mode is set, the probability variation means 56 instructs the ordinary profit state generation means 57 described later to give a predetermined profit. This is also a profit state advantageous to the player. When the normal profit state generating unit 57 receives the above-described probability variation instruction from the probability variation unit 56, the normal profit state generating unit 57 sets the normal electric unit 20a of the special symbol starting unit 20 to a normal time (for example, on the condition that the normal symbol is “winning”). , About 0.5 seconds) (for example, about 3 seconds), the player is provided with a profit state in which the game ball can easily enter, for example, by opening.
[0041]
The special profit state generating unit 58 further receives a determination result of the jackpot from the determining unit 54, or the predetermined profit included in the game control on condition that the stop symbol after the change of the special symbol display unit 23 becomes a jackpot symbol. The opening / closing plate 21a of the special winning opening means 21 is opened / closed as described above by the profit state generation routine. The symbol variation determining means 55 determines, according to the determination result from the determining means 54, a variation pattern designation command for a normal symbol related to a hit, a left symbol, and a right symbol for a normal symbol with a predetermined lottery program. The symbol designating command for this is determined by lottery.
[0042]
The symbol variation determining means 55 further determines, by lottery, a special symbol variation pattern designation command for the big symbol and a symbol designation command for the left symbol, the middle symbol, and the right symbol for the special symbol. Further, the symbol variation determining means 55 determines a variation pattern designation command for detachment and a symbol designation command for detachment by lottery when the symbol is “out” with respect to the normal symbol and the special symbol. The command transmission / reception unit 59 sequentially transmits the normal pattern and special symbol variation pattern designation commands and symbol designation commands to the sound lamp control unit 80.
[0043]
Here, in particular, for example, nine types of variation patterns (for example, nine types “HPC01” to “HPC09” shown in FIG. 8) are provided as variation patterns designation commands for special symbols, and “HPC01 to HPC05” in the first half are provided. The variation pattern of “HPC06 to HPC09” in the latter half is for losing. By the way, the winning counting means 60 counts the game balls to be won in the normal winning means 19, the special symbol starting means 20, and the specific winning area 21b and the normal winning area 21c which are included in the large winning opening means 21.
[0044]
Accordingly, the command transmission / reception means 59 transmits a payout command command for instructing the payout of game balls based on the number of game balls received by the winning counting means 60 to the payout control means 100, and from the payout control means 100. Receives the confirmation command, the payout completion command, and the error occurrence command received from the command. The command transmission / reception means 59 further transmits and outputs to the control means 80, 90, 100 to which various control commands such as a hold number information command relating to the number of game balls held and a probability change information command indicating a probability change state are to be sent.
[0045]
The voice lamp control means 80 includes a command transmission / reception means 81, a fluctuation pattern storage means 82, a fluctuation pattern determination means 83, a random number generation means 84, a lighting control means 85, a voice generation control means 86, and the like. The command transmission / reception unit 81 receives the variation pattern designation command and the symbol designation command from the command transmission / reception unit 59 of the main control unit 50 and also transmits the variation pattern designation command and the symbol designation command to the command transmission / reception unit 91 of the symbol control unit 90.

The variation pattern storage unit 92 stores variation pattern information related to symbol variation in which a variation content (including variation time) is associated with each of a plurality of variation pattern designation numbers for normal symbols and special symbols.
[0049]
The variation pattern determination unit 93 selects variation pattern information corresponding to the variation pattern designation command, and when a plurality of options are provided in the variation pattern information, a predetermined number of random number generation unit 94 generates a predetermined number. One of the control random numbers is extracted, and one option is determined based on the extracted control random number.
[0050]
In the background display data storage unit 95, as shown in FIG. 7, the “universe” with the background number BN1 (see FIG. 13A), the “ocean” with the background number BN2 (see FIG. 13B), “Town” with background number BN3 (see FIG. 13C), “desert” with background number BN4 (see FIG. 13D), “mountain” with background number BN5 (see FIG. 13E), In addition, “savanna” (see FIG. 13F) with a background number BN6 is stored. However, each of these six types of symbol backgrounds stores display data in a range that is a multiple of the horizontal width of the liquid crystal display 16 and can be scrolled in the horizontal direction.
[0051]
The background switching means 96 has probability changing means 96a, and sequentially switches the six types of symbol backgrounds (background number 1 to background number 6) stored in the background display data storage unit 95 by the background switching control shown in FIG. The display is controlled. Therefore, the background switching means 96 includes background switching probability tables KT1 to KT6 (see FIGS. 8 to 9) corresponding to a part of the probability changing means 96a and background switching modes M1 to M6 (see FIGS. 10 to 11). ).
[0052]
  In each of these background switching probability tables KT1 to KT6, the contents of the designation command and the background switching probability are stored in association with each other for the nine types of variation pattern designation commands HPC01 to HPC09. As for these background switching probability tables KT1 to KT3, as shown in FIG. 8, the number of special symbol fluctuations is alternatively selected as a parameter. Here, in the background switching probability tables KT1 to KT6 corresponding to the probability changing means 96a, the variation pattern designation commands HPC02 and HPC0 are displayed.4And for even stop symbols (“2”, “4”, “6”...), Do not switch the symbol background.Naing.
[0053]
However, when the variation pattern designation command HPC05 is received, one of the background switching probability tables KT4 to KT6 is selected using the variation number of the special symbol as a parameter, as shown in FIG. In each of the background switching modes M1 to M6, a background switching random number acquisition value and a symbol background switching order are stored in association with each other for each of the nine types of variation pattern designation commands HPC01 to HPC09.
[0054]
These background switching modes M1 to M3 are applied when a variation pattern designation command HPC other than the variation pattern designation command HPC05 is received as shown in FIG. 10, and the background switching modes M4 to M6 are illustrated in FIG. As shown in FIG. 11, it is applied when a variation pattern designation command HPC05 is received. Here, the background switching modes M1 and M4 are modes for switching the background number BN to “+1” and switching to the next symbol background (for example, BN1 → BN2, BN2 → BN3, BN3 → BN4,...).
[0055]
The background switching modes M2 and M5 are modes in which the background number BN is “+2” to switch to every other symbol background (for example, BN1 → BN3, BN2 → BN4, BN3 → BN5,...). Furthermore, the background switching modes M3 and M6 are modes for switching the background number BN to “-1” and switching to the previous symbol background (for example, BN1 → BN6, BN6 → BN5, BN5 → BN4,...). . Here, the acquired values of the background switching random numbers are 50 random numbers from “0” to “49”, and the change pattern designation command, the symbol designation command subsequent thereto, and the random number value obtained by random number lottery are used. Based on this, any one of the background switching modes M1 to M3 or any one of the background switching modes M4 to M6 is selected.
[0056]
  The display device control unit 97 transmits and outputs various symbol display signals related to symbol variation received from the variation pattern determining unit 93 to the liquid crystal driver 98, and the background display signal of the symbol background received from the background switching unit 96. To send output. Therefore, the display parts 23a-23c of the special symbol display means 23InThe special symbols are displayed in a variable manner, and the normal symbols are variably displayed on the display portions 24a and 24b of the normal symbol display means 24. In addition, the display screen of the liquid crystal display 16 except for the normal symbol display means 24 is displayed on substantially the entire display screen. The design background is displayed while scrolling in the horizontal direction.
[0057]
The payout control means 100 includes a command transmission / reception means 101, a payout / ball lending control means 102, and the like. Based on a payout command command received from the main control means 50 via the command transmission / reception means 101, the payout / ball lending is performed. The means 35 is instructed to pay out the game ball. Here, when the external interface means 105 does not receive any payout error from the payout / ball lending control means 102, the player transmits the firing permission signal to the firing control means 106. When operated, the launch motor 13 is driven by the launch control means 106 so that a game ball can be launched.
[0058]
Next, background switching control executed by the background switching means 96 of the symbol control means 90 will be described based on the flowchart of FIG. However, the symbol Si (i = 11, 12, 13,...) In the figure is each step.
When the main power is turned on to the pachinko machine 2, this control is started. First, an initial value “1” is set as the background number BN, and an initial value “0” is set as the number of fluctuations HN (S11).
[0059]
Next, when the variation pattern designation command is not received (S12: No), when a predetermined time (for example, 5 to 7 minutes) has not elapsed since the symbol variation in the special symbol display means 23 is stopped, that is, a game Since the player continues to play the game and the special symbol variation is frequently performed (S21: No), S12 and S21 are repeatedly executed. Next, when a variation pattern designation command and a symbol designation command subsequent thereto are received (S12: Yes), if the probability is currently varying (S13: Yes), this background switching control is not performed. It has become.
[0060]
However, when the state is not the probability variation state (S13: No), since the special symbol variation occurs, the variation number HN is incremented by one (S14). Next, one background switching probability table KT1 to KT6 is alternatively selected based on the number of fluctuations HN (S15). That is, the background switching probability table KT1 is selected when the variation number HN is “0” to “29”, and the background switching probability table KT2 is selected when the variation number HN is “30” to “59”. For the number of fluctuations HN of “60” or more, the background switching probability table KT3 is selected.
[0061]
However, in this case, when the variation pattern designation command is “HPC05” and “per reach 3”, as shown in FIG. 9, one background switching probability table KT4 to KT6 based on the variation number HN. Is alternatively selected. For example, when the variation count HN is “29” or less, the background switching probability table KT4 is selected. Next, a symbol background switching lottery is performed with the background switching probability corresponding to the variation pattern designation command (S16).
[0062]
That is, when any one of the background switching probability tables KT1 to KT3 is selected according to the special symbol variation frequency HN, whether or not to switch the symbol background is determined by the background switching probability determined by the variation pattern designation command. It is determined. In this case, when the variation pattern designation command HPC for detachment is received, the design background becomes more difficult to switch as the variation frequency HN increases.
[0063]
However, the symbol background is not switched when receiving the variation pattern designation commands HPC02 and HPC04 for jackpots with even symbols. When any one of the background switching probability tables KT4 to KT6 is selected, whether or not to switch the symbol background is determined by lottery based on the background switching probability determined by the left symbol designating command “L: ZC”. If the symbol background is not switched as a result of the lottery (S17: No), S12 and subsequent steps are executed. If the symbol background is switched (S17: Yes), the symbol background switching mode lottery is performed. That is, one of the background switching modes M1 to M6 is selected by lottery (S18).
[0064]
Next, a switching display for switching to the next symbol background is executed based on the selected symbol background switching mode (S19). Then, the background that is switched and the currently displayed background is set to the background number BN (S20), and the steps after S12 are repeatedly executed. However, since the continuous game by the player has ended, when the predetermined time has elapsed since the symbol variation stopped (S21: Yes), the variation frequency HN is reset to the initial value “0” (S22). . Therefore, at the next switching of the symbol background, the symbol background of the background number BN currently displayed is switched.
[0065]
Next, the design background switching control will be described in detail.
For example, when the variation number HN is “15” when the variation pattern designation command “HPC01” is received, the background switching probability table KT1 of the three background switching probability tables KT1 to KT3 shown in FIG. Selected. Then, based on the background switching probability “40/50” designated by the variation pattern designation command “HPC01” in the background switching probability table KT1, lots are selected for symbol background switching.
[0066]
As a result of the lottery, when the background switching is won, one of the background switching random numbers (0 to 49) is acquired. For example, when the acquired random number value is “10”, the acquired value The background switching mode M1 corresponding to “10” and the fluctuation pattern designation command “HPC01” is selected. Therefore, a switching mode for switching the symbol background to the next symbol background is determined. As a result, for example, when the “universe” shown in FIG. 13A is displayed as the symbol background at the start of the variation of the special symbol, the symbol background is switched to “sea” with the background number BN2. During the change display, the symbol background of the “sea” is scrolled in the horizontal direction.
[0067]
In this way, one background switching probability table is provided on the symbol control means 90 side based on the variation pattern designation command and symbol designation command received from the main control means 50 and in accordance with the number of symbol fluctuations, that is, in association with the gaming state. Since KT is selected, it is possible to improve the performance of the notice effect. Further, when the background switching is won, one background switching mode is selected based on the variation pattern designation command or symbol designation command and the background switching random number acquisition value, and the symbol background is selected based on the selected background switching mode. Since the symbol backgrounds are sequentially switched, the reliability of the notice can be varied according to the symbol background switching mode, that is, depending on the symbol background switching method.
[0068]
The notice in this case is a reach notice, a jackpot notice, a probability change notice, etc., and the reliability of the notice is a reliability that develops into a reach, a reliability that develops into a jackpot, a reliability that develops into a probability change, and the like. Further, the notice effect includes an effect of developability to reach, an effect of developability to jackpot, and an effect of developability to probability change. Here, a background display data storage unit 95 is constituted by a microcomputer, its RAM, and the like included in the symbol control means 90, and the background switching means 96 is provided by a background switching control (see FIG. 12) stored in the microcomputer, its ROM. The probability changing means 96a is configured by the background switching probability table KT or the like stored in the microcomputer or the ROM.
[0069]
Next, a modified form of the embodiment will be described.
1] As shown in FIG. 14, the background switching probability tables KT1 to KT3 in FIG. 8 are partially changed. When the previous left stop symbols are "1" to "4", the background switching probability table KT11 is changed. When the previous left stop symbol is “5” to “8”, the background switching probability table KT12 is selected. When the previous left stop symbol is “9” to “C”, the background switching probability table is selected. KT13 may be selected.
[0070]
In this case, for example, when the symbol background is switched when the previous left stop symbol is any of “9” to “C”, there is a high possibility that the odd symbol will be a big hit. However, when the variation pattern designation command “HPC05” is received, the same probability as in FIG. 9 may be set. In this case as well, based on the variation pattern designation command and the symbol designation command received from the main control means 50, and depending on the previous stop symbol, that is, in association with the gaming state, one symbol on the background control means 90 side Since the table KT is selected, it is possible to improve the performance of the notice effect.
[0071]
2] As shown in FIG. 15, the background switching probability tables KT1 to KT3 in FIG. 8 are partially changed, and the current symbol background (background number) is switched from “1” or “4”. In this case, the background switching probability table KT21 is selected, and when switching from either “2” or “5”, the background switching probability table KT22 is selected and switched from either “3” or “6”. In this case, the background switching probability table KT23 may be selected.
[0072]
In this case, for example, when the current symbol background is switched from either “3” or “6”, it is highly likely that the odd symbol symbol will be a big hit. However, when the variation pattern designation command “HPC05” is received, the same probability as in FIG. 9 may be set. Also in this case, one background switching is performed on the symbol control means 90 side in accordance with the background pattern before switching, that is, in association with the gaming state, based on the variation pattern designation command and the symbol designation command received from the main control means 50. Since the probability table KT is selected, it is possible to improve the performance of the notice effect.
[0073]
3] As shown in FIG. 16, the background switching probability tables KT1 to KT3 of FIG. 8 are partially changed, and the background switching probability table KT31 is selected from 10 am to 2 pm, and 2 pm to 2 pm The background switching probability table KT32 may be selected until 6 o'clock, and the background switching probability table KT33 may be selected after 6 pm. In this case, for example, when the background changes during the game after 6 pm, there is a high possibility that the odd symbol will be a big hit.
[0074]
However, when the variation pattern designation command “HPC05” is received, the same probability as in FIG. 9 may be set. Also in this case, in order to select one background switching probability table KT on the symbol control means 90 side according to the variation pattern designation command and the symbol designation command received from the main control means 50 and according to the game time zone, The performance of the notice effect can be improved.
[0075]
4] As shown in FIG. 17, the background switching mode M11 to M13 may be selected on the basis of the background switching random number acquisition value by partially changing FIG. That is, when the background switching mode M11 is selected based on the acquired value of the random lottery, the symbol background is switched at the start of the change of the special symbol, and when the background switching mode M12 is selected, the first symbol is selected. When the symbol background is switched when the (for example, the left symbol) is stopped and the background switching mode M13 is selected, the symbol background is switched when the second symbol (for example, the right symbol) is stopped.
[0076]
In this case, for example, when the symbol background is switched when the second symbol is stopped, it is always a big hit with odd symbols. Also in this case, the reliability of the notice can be made different according to the symbol background switching mode, that is, according to the timing when the symbol background is switched. Here, the timing at which the symbol background is switched may be when the reach mode occurs, when it comes off temporarily, or when it is a big hit temporarily stop.
[0077]
5] As shown in FIG. 18, one part of the background switching modes M21 to M23 may be selected on the basis of the background switching random number acquisition value by partially changing FIG. That is, when the background switching mode M21 is selected based on the acquired value of the random lottery, the symbol background is switched to either “1” or “4” and the background switching mode M22 is selected. The symbol background can be switched to either “2” or “5”.
[0078]
Further, when the background switching mode M23 is selected, the symbol background can be switched to either “3” or “6”. In this case, for example, the background switching mode M23 is selected, the symbol background “3” is switched to “city” or the symbol background “6” “savanna”, and the symbol background “city” or “savanna” is scrolled horizontally. When displayed, it is always a big hit with odd symbols. Also in this case, the reliability of the notice can be varied according to the symbol background switching mode, that is, according to the symbol background switched.
[0079]
6] As shown in FIG. 19, one part of the background switching modes M31 to M33 may be selected based on the background switching random number acquisition value by partially changing the above FIG. That is, when the background switching mode M31 is selected based on the acquired value of the random number lottery, the symbol background is “white-out” and switched, and when the background switching mode M32 is selected, the symbol background is changed. When “blackout” is switched and the background switching mode M33 is selected, the symbol background is “flashed” and switched.
[0080]
In this case, for example, when the symbol background is “flushed” and switched, it is always a big hit with odd symbols. Also in this case, the reliability of the notice can be varied according to the symbol background switching mode, that is, according to the animation for switching the symbol background. Here, the animation for switching the symbol background may be “fade-in”, “fade-out”, “wipe-in”, “wipe-out”, or “spiral”.
[0081]
6] As shown in FIG. 20, in the background display data storage unit 95, display data for displaying a notice character having a notice function specific to each symbol background is additionally stored. When displayed, the character may be displayed based on the notice probability. Here, the notice probability for displaying each notice character is “hit (if it becomes a big win through the reach state)”, “out of reach (if it comes out through the reach state)” and “ Each of the “normal deviation (when it is released without going through the reach state)” is set differently in advance.
[0082]
The notice characters “UFO”, “Dolphin”, “Airship”, “Camel” and “Monkey” are characters having a notice function specific to the symbol backgrounds “1” to “5”, respectively. Therefore, the notice character can appear so as to become familiar with the design background. In this case, when the notice character “Dolphin” is displayed while “Sea” of the symbol background 2 is displayed (see FIG. 13B), the reach is always reached.
[0083]
In addition, when the notice character “airship” is displayed while the “city” of the symbol background 3 is displayed (see FIG. 13C), it is always a big hit. Further, when the character “monkey” is displayed while the “mountain” of the symbol background 5 is displayed (see FIG. 13E), it becomes a big hit if the reach is reached. Here, “savanna” of the symbol background 6 does not have any notice character, but is set only for high probability. Thereby, it is possible to express that the reliability of the jackpot is high by displaying the notice character corresponding to the symbol background.
[0084]
  7] The temporary stop symbol is determined by lottery based on the symbol background.BackgroundAccordingly, the temporary stop symbol may be determined by lottery, and the promotion rate from the even symbol to the probability variation symbol (odd symbol) may be varied. 21 shows a temporary stop symbol selection table for the symbol background “1”, FIG. 22 shows a temporary stop symbol selection table for the symbol background “2”, and FIG. 23 shows a temporary stop symbol selection table for the symbol background “3”. Is shown. However, since the symbol backgrounds “4” to “6” are the same here, the description thereof is omitted.
[0085]
  In other words, in FIG. 21, among the 20 lottery values from “0” to “19”, only half of “10” to “19” can be promoted from an even symbol to an odd symbol. Therefore, the promotion rate is1/2As shown in the right end part of FIG. 21, the “odd” definite symbol and the “even” definite symbol can be combined as illustrated. In addition, in FIG. 22, any lottery value from “0” to “19” can be promoted from an even symbol to an odd symbol.
[0086]
  Therefore, the promotion rate is ½, and as shown in the right end portion of FIG. 22, the “odd” definite symbol and the “even” definite symbol can be combined as illustrated. Further, in FIG. 23, the lottery values “10” to “19” can be promoted from the even symbol to the odd symbol. Therefore, the promotion rate is1/2As shown in the right end of FIG. 23, it is also possible to collect “odd” definite symbols and “even” definite symbols as illustrated.
[0087]
However, in this case, the even number symbol “6” is not easily promoted to an odd number symbol, and the even number symbol “4” is easily promoted to an odd number symbol. Thus, since the temporary stop symbol is selected by lottery based on the symbol background after confirming the symbol background and the confirmed symbol, it is possible to further improve performance and game performance.
[0088]
8] In the background switching probability tables KT1 to KT3 shown in FIG. 8, for the variation pattern designation command “HPC05”, the background switching probability is set based on the variation pattern designation command “HPC05” without being based on the symbol designation command. For all the variation pattern designation commands other than the variation pattern designation command “HPC05”, the background switching probability may be set based on the symbol designation command in the same manner as the variation pattern designation command “HPC05”. Good.
[0089]
  9] The background switching modes M1 to M6 shown in FIG. 10 and FIG. 11 may also be selected in association with the gaming state, such as based on the number HN of special symbol variations, as in the background switching probability tables KT1 to KT6. Good.
  10] One of the background switching probability tables KT1 to KT6 may be alternatively selected by random lottery.
  11] The game state is the number of changes (see the embodiment), the previous stop symbol (see FIG. 14), the symbol background before switching (see FIG. 15), the game timeband(Refer to FIG. 16) and the like, for example, may be the number of reserved balls, the number of fluctuations after the power is turned on, after the big hit, and after the symbol background switching, the elapsed time, and the like.
[0090]
  12] The symbol background is the effect image displayed on the symbol display means 22CatchI can. The notice character displayed on the symbol display means 22 is also similar to the effect image.CatchSimilarly, special images can also be represented in a broad sense as production images.CatchI can. Therefore, the present invention switches at least a part of the design background that is the effect image.GetIn addition, it may be a case where at least a part of the notice character as the effect image is switched, or at least a part of the pattern or shape of the special symbol is changed.
[0091]
13] The present invention is not limited to the embodiment described above, and the present invention is also applied to the case where various changes are made without departing from the gist of the present invention and a continuous advance notice is developed. Is possible. Furthermore, the present invention can be applied not only to pachinko machines but also to various ball game machines such as an arrange ball machine and a sparrow ball game machine that use various game media such as game balls and coins.
[0093]
【The invention's effect】
  According to the invention of claim 1, the effect control means controls the symbol display means by controlling the symbol display means based on the variation pattern designation command transmitted from the game control means, and at the time of the symbol background display control. In the background display data storageCorresponding to the background numberUsing the stored display data of multiple types of symbol backgrounds and background switching means, the received variation pattern designation command and the number of variations of special symbols during continuous games for each player are set as parameters.TakiriReplacement probability tableTo decide whether to switch the design background. When the design background switching is determined, the background switching means selectively selects the background switching mode by random lottery from a plurality of preset background switching modes corresponding to the received variation pattern designation command, The next background symbol is determined based on the selected background switching mode and the background number of the symbol background currently displayed.The performance of the notice effect can be greatly enhanced. Other claims 2 to5This invention has the same effect as that of the first aspect.
