Description

  The present invention relates to a gaming machine, and more particularly, to a so-called seven machine, a winged article, a right article, an arrangement ball or the like.

  As a conventional ball ball game machine, various game contents called a so-called seven machine, a right item, or an arrangement are widely used. For example, when a game ball wins (starts winning) or passes through the start winning opening, the seven machine displays the special symbol in a variable display on the variable display device. When the display state of the variable display device becomes a specific one, for example, at the time of big hit, a reach display is first performed, and a combination of special symbols displayed on the three display units is a specific zoro such as “777”. In the case of a combination of eyes, the special winning opening is configured to be opened. The big prize opening is closed once a predetermined number of game balls have won or a predetermined time has elapsed, but if the game ball passes through a specific area formed in the big prize opening during the opening, It is configured to open and repeat the opening and closing operations up to 16 times (so-called special game).

  The side operating the pachinko hall (also referred to simply as the hall side) gives a bonus to the player separately after the big hit. For example, when the combination of special symbols such as “777” is an odd number of doubles, the game can be continued until “444” or “666” is hit without exchanging (counting) the acquired game balls. It is a business form. This business form is called a lucky number system (also referred to as an LN system by taking the initials). The lucky number is an odd number of double eyes in the above example. On the other hand, arrangements such as “444” and “666” are also referred to as exchange symbols.

Lucky numbers and exchange patterns are basically set on the hall side regardless of the specifications of the gaming machine, but in Patent Document 1, a lucky number and an unlucky number are set on the gaming machine side. A technique that can change the occurrence rate of a lucky number is disclosed. The lucky number, the unlucky number, and the lucky number occurrence rate are set by pressing a push-button switch.
JP-A-6-296735

  However, the above prior art merely allows the setting of the lucky number and the occurrence rate on the hall side, and the player side cannot be involved. Recently, the number of holes that can continue to play without counting the number of game balls, regardless of the design, is not the LN system, so there is a problem that the LN system halls are struggling in business. . Further, if the LN system is not used, the start winning frequency and the number of balls are reduced by adjusting the nail accordingly, which is disadvantageous for the player.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a gaming machine that can obtain a gaming interest even in an LN hall.
Another object of the present invention is to make it possible for a player to feel that he / she can play a game advantageously in a hall in an LN business form.

Another object of the present invention is to enable a player to receive a privilege with a high probability.
Another object of the present invention is to prevent a player from having anxiety that “the probability may not change”.

Another object of the present invention is to give a thing close to a privilege called morning.
Another object of the present invention is to prevent the hall side from being damaged due to the occurrence of a higher probability of granting a privilege while maintaining a new gaming interest.

Another object of the present invention is to prevent the probability that the exchange symbol is displayed and prevent the hole side from being damaged.
Another object of the present invention is to make it possible for the player to feel that the game can be advantageously played by substantially reducing the exchanged symbols, or to be able to actually benefit the player. There is to do.

  Another object of the present invention is to make it possible to freely set exchange symbols without the hole side being caught in an advantageous disadvantage.

In order to achieve the above object, according to the first aspect of the present invention, a game board in which a game area is formed, variable display means provided on the game board and capable of variably displaying a plurality of types of symbols, and the game board And a variable display control means for performing a variable display of the symbol for a predetermined period in the variable display means when the game ball wins a prize to the specific winning opening, and the variable display control means When the symbol displayed after the end of the variable display becomes a predetermined specific symbol arrangement, after the end of the variable display by the privilege giving means for granting a privilege to the player, and the variable display control unit Probability determining means for deciding which of the two types of high and low probabilities preset as the probabilities that the arrangement of a specific symbol is displayed on the variable display means, and the two kinds of probabilities Of which If the probability determining means determines that the probability is to be a higher probability, the variable display means displays an ascending array display means for displaying an ascending array which is a predetermined symbol array, and the two types of If the probability determining means determines that the probability is the lower one of the probabilities, the variable display means has a reduction that is a predetermined symbol arrangement different from the ascending arrangement. In a gaming machine provided with a lowered arrangement display means for displaying an arrangement, there are a plurality of types of the lowered arrangement, and a selection means for a player to select a desired arrangement from the plurality of kinds of lowered arrangements, Of the two types of probabilities, when the probability determining means determines the lower probability, the lowered array display means excludes the selected array that is the lowered array selected by the selecting means. Multiple Characterized in that it is used for displaying any reduction sequence classes in the variable display means.

  According to the gaming machine configured as described above, the following service can be performed in the hall of the LN business form. That is, in such a hole, the hole side places the exchange symbol in one of the lowered arrangements, and indicates this in a place that is visible to the player. That is, when the lowered arrangement is displayed on the variable display means, the player must exchange the acquired game balls. Then, many players think that they do not want to exchange game balls (i.e., want to continue playing with the acquired game balls), so they select the exchange symbol using the selection means. That is, the selected arrangement is used as an exchange symbol. As a result, the lowered array display means never displays the selected array when the probability that a specific array is displayed is low (if it is already low, the state is maintained). As a result, at least in appearance, the replacement symbols are not displayed on the variable display means by the lowered arrangement display means (if there are a plurality of exchange symbols and some of them are selected arrangements, they may be displayed. Therefore, the player can feel that the game can be advantageously performed. Further, depending on the mode, the player is actually advantageous. Note that whether or not the player is actually advantageous can be set by adopting a mode described later.

  Note that the hole side rarely uses the ascending arrangement as an exchange symbol. Because, when the ascending arrangement is displayed on the variable display means, the probability that a specific symbol arrangement is displayed is increased, so that even if the game ball is exchanged, the player will receive a privilege without being far away. This is because there is not much meaning to exchange game balls. In particular, when the privilege is “acquisition of game balls”, even if the game balls are exchanged just because the ascending arrangement is displayed, the player acquires the game balls early and late, which is meaningless.

  As benefits other than “acquisition of game balls”, it is easier to enter a specific winning opening, the time for variable display is shortened, and the probability determination means determination is the higher of the two types of probabilities. In the right object, it is possible to enter the right acquisition hole, or a combination of these (including “acquisition of game balls”).

  Further, most of the models having the current probability variation function (probability determining means) have a plurality of “specific symbol arrangements”, and all of them are double-sided. A part of them is an ascending arrangement (so-called proboscis design), and the rest is a descending arrangement (so-called normal design meromorph). Therefore, it may be configured such that the lowered arrangement (in this case, “444”) can be selected by selecting one of the symbols (for example, 4) forming the lowered arrangement.

  Further, whether or not to select a desired arrangement via the selection means may be arbitrary by the player. That is, a reduced sequence may be selected from a plurality of types of reduced sequences, or may not be selected at all. If not selected, there will be no selection sequence. Further, a plurality of selection arrays may be specified. Even in such a configuration, at least one lowered sequence remains (that is, all the lowered sequences cannot be selected sequences).

The present invention is defined in claim 2, the gaming machine according to claim 1, of the two kinds of probability, if it is determined by that the higher probability, and the probability determining means, said rise The array display means displays the selected array once on the variable display means, and then displays the ascending array on the variable display means.

  According to the gaming machine configured as described above, the selection arrangement is not displayed without setting the complicated rules as described above, so that the gaming machine is easy to understand for the player and has increased interest. This is a gaming machine that has an advantage in that it is easy for the hall side to judge whether it is exchanged or not exchanged. Specifically, it is as follows.

  For the player, it is difficult to know whether the selected array is actually not displayed or it is not displayed by chance only by the selected array not being displayed on the variable display means. In this regard, as in the gaming machine of the present invention, once the selected sequence is displayed (referred to as temporary stop) and then the ascending sequence is displayed (referred to as final stop), the “selected sequence is displayed. Then, the player is given an impression that “the player will be promoted to the ascending arrangement”, and therefore, it is possible to obtain the game entertainment “the selected arrangement is promoted”. In addition, the existence value of the selected sequence can be increased. Note that there may be a case where the final stop is not performed, but in this case, it is preferable that the selected array is not displayed by the final stop.

  For the hall side, when operating under the LN system, it is necessary to check whether the exchange symbol or the lucky number is displayed each time the lowering array display means or the ascending array display means operates. If a rule that the arrangement does not have to be exchanged is introduced, it is necessary to determine what the player has selected as the selection arrangement and whether the displayed arrangement is an arrangement to be exchanged. This is not a big decision if there is only one gaming machine of the present invention, but in general, a plurality of gaming machines are installed in one hall, and the selection arrangement of each one may be different, which is extremely complicated. Judgment. In this regard, if it is configured to display the selected array only at the temporary stop as in the gaming machine of the present invention, the hall side determines whether or not it is necessary to replace only from the lower array displayed by the fixed stop or the lower array display means. It is only necessary to make a determination, and it is not necessary to consider the selection arrangement displayed in the temporary stop, so that the determination becomes easy.

According to a third aspect of the present invention, in the gaming machine according to the first aspect , a mark indicating that the ascending arrangement is a higher one of the two types of probabilities is attached. , among the two kinds of probabilities, to higher probability, and if it has been determined by the probability determination unit, when the rising sequence display means for displaying the selected sequence in the variable display means, The selected array to which the mark is added is displayed on the variable display means.

  According to the gaming machine configured in this way, it is possible to create a case where the display is confirmed with the selected sequence, and since the mark indicating that the higher probability is added is added to the selected sequence, the player Can be prevented from having anxiety that “the probability may not change”.

  As a mark, a certain mark is displayed at a predetermined position (for example, upper right) of each symbol that constitutes the ascending arrangement, and the color of each symbol that constitutes the ascending arrangement is different from each symbol that constitutes the descending arrangement. Etc.

According to a fourth aspect of the present invention, in the gaming machine according to any one of the first to third aspects, when the predetermined first condition is satisfied, the selection means cannot select the selection array. characterized in that there.

  According to the gaming machine configured as described above, the gaming machine can be given the privilege of “selecting the selection array” only to the players who have not satisfied the predetermined first condition. In addition, in order to enable the selection means to operate appropriately according to the predetermined first condition, a new game entertainment such as playing a game so that the predetermined first condition is not satisfied can be created. It is also possible for a player to intentionally establish a predetermined condition after selecting a selection sequence in order to make the selection sequence set by himself / herself permanent (usually until the hall is closed). Become.

  Contrary to this, the selection means can be operated at any time (or restarted when some condition (which may be the same as or different from the predetermined condition) is satisfied even if the selection means is temporarily inactive). If this is done, it becomes possible to change the selection sequence set by the player who has played before to a selection sequence that he / she likes, or to further add a selection sequence that he / she likes. It is also possible to deal with the harassment that “the lowering array other than the exchanged symbols is a selected array”. If such harassment of the hall is performed, the possibility that the exchanged symbol is displayed is not changed at least in appearance, so that the gaming interest of the gaming machine of the present invention is impaired. In this respect, by making the selection means operable at any time as described above, the exchanged symbols can be changed to the selected arrangement, and the game entertainment can be restored.

  Specific examples of the “predetermined first condition” include a predetermined number of times, a game ball has won a special prize opening (hereinafter also referred to as a specific prize or a start prize), and a privilege granting unit has granted a privilege. The rising sequence is displayed on the variable display means. The following may also be used.

According to a fifth aspect of the present invention, in the gaming machine according to the fourth aspect , the predetermined first condition is established when a predetermined time elapses after the gaming machine is turned on. It is characterized by that.
According to the gaming machine configured as described above, it is possible to give a privilege that “a selection array can be selected” to the player until a predetermined time elapses. This is close to a privilege called morning. For example, the predetermined time may be 2 hours, but it is more preferable that the predetermined time can be changed according to the convenience of the hall, such as the time when the power is turned on and the time when the morning is desired to end.

According to a sixth aspect of the present invention, in the gaming machine according to any one of the first to fifth aspects, the lower probability of the two types of probabilities when the predetermined second condition is satisfied. When the probability determining means determines that the reduced array display means displays any of the plurality of types of reduced arrays including the selected array on the variable display means. It is characterized by.

  According to the gaming machine configured in this way, when the predetermined second condition is satisfied, even if the probability determining means determines that the lower probability is set, the gaming machine is displayed with the selected array. . That is, when the predetermined second condition is satisfied, the selected arrangement becomes close to or exactly the same as the original reduced symbol. As a result, when the player places the exchange symbol in the selected arrangement, the privilege that “the exchange does not have to be displayed even if the selection arrangement is displayed” is obtained at least until the predetermined second condition is satisfied. It will be a gaming machine that has a gaming appeal. Specific examples of the “predetermined second condition” include a predetermined number of times, a specific winning, a privilege giving means giving a privilege, a rising array displayed on a variable display means, a power supply For example, a predetermined time has passed since the charging.

  Further, it is desirable that the ascending array display means not display the selected array when the predetermined second condition is satisfied. However, when the ascending arrangement display means is configured to make a fixed stop after a temporary stop, the selected arrangement may be displayed with a temporary stop. Further, when the mark is attached to the ascending array and the ascending array display means is configured to display the selected array with the mark added, after the predetermined second condition is satisfied, It is preferable that the display is not performed, and the lower array display means displays the selected array without adding the mark.

According to a seventh aspect of the present invention, in the gaming machine according to any one of the first to sixth aspects, the probability deciding means is adapted to determine whether the selection sequence is selected by the selection means. It is characterized in that the occurrence rate of the type probability is constant.

  As described above, when a part of the lowered sequence becomes the selected sequence, the lowered sequence is substantially reduced, and it seems that the probability that the raised sequence is displayed is increased. According to the configured gaming machine, the probability that an ascending array or a selected array is displayed is the same as when no selected array is selected, regardless of how many selected arrays are selected, so the higher probability It does not happen that the hall side loses too much.

  Temporarily, there are 10 kinds of specific symbol arrangements, 5 of which are ascending arrangements (with the above-mentioned mark), and the remaining 5 are descending arrangements. When one selected arrangement is selected, the selected arrangement is displayed. The ascending arrangement display means and the descending arrangement display means are configured to display a specific symbol arrangement that can be displayed at an equal ratio, respectively, and the probability determination means includes two types of high and low Are generated with a probability of 1/2 (probability under the condition that “privilege is given by the privilege granting means”, the same applies hereinafter).

  That is, when the selected array is not selected, the ascending array display means displays the five kinds of ascending arrays with a probability of 1/5, and the descending array display means displays the five kinds of descending arrays with 1/5 each. Display in probability (actually, the two types of high and low probabilities are generated at a rate of 1/2 as described above, so that the ascending array and the decreasing array are generated with a probability of 1/10). When one selected array is selected, the ascending array display means displays 5 kinds of ascending arrays and 6 kinds of arrays composed of the selected arrays with a probability of 1/6, and the descending array display means displays the selected array. The four types of lowering sequences except for are displayed with a probability of 1/4 (actually, each ascending sequence is generated with a probability of 1/12, and each decreasing sequence is generated with a probability of 1/8). Thus, regardless of the selection of the selected array, the probability of occurrence of the two types of high and low probabilities is constant (in this example, 1/2), so the higher probability occurs too much and the hole side loses. That's not true.

As described above, the gaming machine according to the present invention can feel that a player can play a game advantageously in a hall in an LN business form.
Further, if the player places the exchanged symbols in the selection arrangement via the selection means, even if the selection arrangement is displayed on the variable display means, the player can receive a privilege with a high probability.

  And, for the player, it is possible to obtain a gaming interest that “the selected arrangement is promoted”. In addition, the existence value of the selected sequence can be increased. For halls operating under the LN system, it is only necessary to determine whether or not replacement is necessary based on the confirmed stop or the lowered arrangement displayed by the lowered arrangement display means, and it is not necessary to consider the selection arrangement displayed in the temporary stop. The judgment will be easier.

  In addition, it is possible to create a case where the selected sequence is confirmed, and a mark indicating that the higher probability is added is added to the selected sequence, so that the player may “may not change the probability”. You can prevent anxiety.

  Further, if the gaming machine can give the privilege of “selecting the selection arrangement” only to the players who have not satisfied the predetermined first condition, the selection means can be appropriately operated under the predetermined first condition. Therefore, it is possible to create a new game entertainment such as playing a game so that the predetermined first condition is not satisfied. In addition, depending on the predetermined first condition, the player can intentionally establish the predetermined condition after selecting the selected array in order to make the selected array set by the player semi-permanently valid. Become.

Further, until a predetermined time elapses, it is possible to give a player a privilege called “morning” that gives the player the privilege of “selectable selection can be selected”.
When the predetermined second condition is satisfied, even if the probability determining means determines that “the lower probability is set”, the player selects the exchange symbol if the selected arrangement is displayed. In the case of the arrangement, it is a gaming machine with a gaming interest that a privilege that “there is no need to exchange even if the selected arrangement is displayed” can be obtained at least until the predetermined second condition is satisfied. .

  In addition, when a part of the lowering sequence becomes a selection sequence, the lowering sequence is substantially reduced, and it seems that the probability that an ascending sequence is displayed is increased. The probability that is displayed is the same as when no selected array is selected no matter how many selected sequences are selected, so the higher probability will occur too much and the hole side will be lost. Absent.

  As shown in FIG. 3, a substantially circular gaming area 11 is formed on the gaming board 10 by an outer rail 14 and an inner rail 15 provided on the surface of the gaming board 10. In the game area 11, there are a central device 26, a first type starting port (ordinary electric accessory) 17, a variable winning device 18, a left winning port 19, a right winning port 209, a lower left winning port 21, a lower right winning port 22, A number of obstacle nails 23, a pair of lamp windmills 24, 25, and the like are arranged.

As shown in FIG. 3, the central device 16 is disposed at a substantially central portion of the game area 11 and includes a center accessory 26 and a liquid crystal display device (liquid crystal display panel) 27.
On the screen of the liquid crystal display device 27, a special symbol display area (identification information display area) for stopping display after a plurality of special symbols (identification information) are displayed while changing one after another in a predetermined direction is formed. (Illustration omitted). That is, a left special symbol display area for displaying a left special symbol, a middle special symbol display area for displaying a middle special symbol, and a right special symbol display area for displaying a right special symbol are formed. Note that the middle special symbol display area is disposed slightly above the left special symbol display area and the right special symbol display area in the screen. In each special symbol display area, a symbol variation direction is set in the vertical direction, and a plurality of symbols (special symbols) as identification information are sequentially displayed so as to vary in that direction.

  The liquid crystal display device 27 changes each special symbol displayed in the display area (not shown) of the video screen when the game ball enters the first type starting port (ordinary electric accessory) 17. Stop display. Then, for example, when the symbols of “777” are arranged in the same three-digit symbols and are stopped and displayed (determined display), the big prize opening 311 of the big prize winning device 31 described later disposed in the variable prize winning device 18 is opened. That is, the gaming machine 1 includes a left special symbol display area, a middle special symbol display area, and a right special symbol display area as “plural identification information”. In addition, each special symbol is changed (that is, a plurality of pieces of identification information are variably displayed) by “satisfaction of a predetermined condition” that “a game ball enters the first type starting port (ordinary electric accessory) 17”. When the stop condition of the specific condition that “the symbols are arranged in the same three-digit pattern” is achieved, a “specific value” of “big hit” is given.

  The center accessory 26 is mounted so as to protrude from the front peripheral portion of the liquid crystal display device 27, and normal symbol operation gates 36 and 37 are provided diagonally below the left and right of the center accessory 26, respectively.

In addition, when a start winning is detected, determination of success / failure is performed based on a random value described later, and for the display mode control such as change of special symbols (including reach display mode) or confirmation based on the determination result Data is read. This data is transmitted via the signal transmission path 500a as a command signal for which the special symbol control unit 160 is an operation command target.

  Next, jobs executed by the main control unit 140 will be described with reference to FIGS. FIG. 14 shows an example of a main job executed by the CPU 401 of the main control unit 140 based on a program stored in the ROM 482.

  First, the stack pointer is set to a predetermined address in the RAM 481 (S10), and it is determined whether or not the RAM clear switch 144 is operated (pressed) (S12). As a result, when the RAM clear switch 144 is operated, the RAM 481 is initialized (S800). On the other hand, when the RAM clear switch 144 is not operated, it is determined whether or not the backup flag is set (S15). As a result, when the backup flag is set, the “recovery processing for power interruption” shown in FIG. 16 is performed.

  Note that the gaming machine 1 performs the processing at the time of occurrence of power interruption shown in the flowchart of FIG. 15 when the power interruption occurs due to a power failure or the like. First, the used register is saved in the RAM 481 (S630), and the value of the stack pointer is saved in the RAM 481 (S632). Then, the special winning opening solenoid 313 and the first type starting opening solenoid 17c are turned off (S634), the polling processing time of the winning ball sensor (for example, about 85 msec) is set (S636), the pre-counting ball sensor and the award After the ball count, the passing of the game ball is monitored by the sensor (S638). Next, when the polling processing time elapses (S640), a checksum (excluding checksum, backup flag, and stack area) of the RAM 481 used is created (S642), stored, and the backup flag is set in the RAM 481 ( S646). Then, access to the RAM 481 is prohibited (S648), and an infinite loop process prepares for power down. It is also possible to execute HALT processing or STOP processing instead of the unlimited loop processing.

  In the “return process” shown in FIG. 16, a checksum is calculated (S664), and it is determined whether or not it matches the checksum stored when the power is turned off (S666). As a result, if the checksums do not match, the RAM 481 is initialized (S800). On the other hand, if the checksums match, the stack pointer before power-off is restored (S668), the backup flag is cleared (S670), and a command for returning the sub-board to the state before power-off is transmitted. (S672). Then, each register is returned to the state before the power is turned off (S674), the permission / non-permission of interruption is returned to the state before the power is turned off (S676, S678), and the address is returned to the address before the power is turned off (S680). In this embodiment, since a backup power supply for power failure countermeasures is added to the gaming machine 1, "information advantageous to the player" that was generated before the power outage was saved even during a pachinko hall power outage, etc. it can.

  Returning to FIG. 14, if it is determined in step S15 that the backup flag is not set, the initialization end is determined (S20). As a result, if the initialization has not ended, the initialization end determination in S20 is performed again after executing the initialization job (S190). Note that the initialization process of the RAM 481 is performed when the gaming machine 1 is turned on for the first time from the shipment state, when the RAM clear switch 144 is operated (pressed), when the backup flag is abnormal, and when the checksum is one. If you did not do it.

  On the other hand, if the initialization has been completed, each job from the LED job (S30) to the switch job (S70) is executed. In the LED job (S30), the display pattern data of the normal symbol and the normal symbol unstarted count, the display pattern data of the special symbol unstarted count, and the like are output. In the constant speed random number job (S40), a special symbol success / failure random number memory, a general-purpose count memory, and the like of the RAM 481 described later are updated. In the non-constant speed random number job (S50), the initial value counter and the off-normal symbol random number memory (not shown) are updated. The general-purpose count memory (not shown) is used, for example, for creating values “0” to “255” for each interrupt, executing command jobs, and decoration jobs.

  In the voice job (S60), data related to music and voice is read, and in the switch job (S70), various detection switches are read. That is, various signals such as the left and right winning opening passing detection signals are taken into the main control unit 140 via the relay board 190, and various signals such as the firing stop detection signal, the touch detection signal, and the volume detection signal are sent to the payout terminal board 191. Via the frame controller 150. Further, the main control unit 140 receives the first type start port winning detection signal from the first type start port winning detection switch 17s, and receives the winning ball detection signal and the normal symbol operation gate passage detection signal from the large winning device 31. It is captured.

  Next, it is determined whether or not there is an abnormality in various switches such as a count detection switch, a count detection and a specific area passage detection switch (S80). As a result, if there is an abnormality (ball clogging or disconnection), an error job (S130) is executed.

  On the other hand, if there is no abnormality, a special symbol main job (S90) and a normal symbol job (S100) are executed. In the special symbol main job (S90), a job related to data necessary for the main controller 140 and the special symbol controller 160 to operate in cooperation is executed. Further, in the normal symbol job (S100), the display pattern data of the normal symbol and the normal symbol unstarted number of times is read.

  Thereafter, the state of each flag is set in the backup memory (S140), and a prize ball signal job (S150), an information signal job (S160), a command job (S170), and a remaining time job (S180) are executed. In the prize ball signal job (S150), data relating to prize ball payout is read and output, and in the information signal job (S160), data necessary for outputting information to other control units is read. Further, in the command job (S170), a command for special symbol management or the like is output, and in the remaining time job (S180), a non-constant random number is called. The initial value random number is also updated in the remaining time job of S180.

  Next, the success / failure determination job executed in the series of the main job will be described with reference to the flowcharts of FIGS. FIG. 17 is a flowchart of the success / failure determination job, FIG. 18 is a flowchart of the jackpot process, and FIG. 19 is a flowchart of the losing process. The success / failure determination job is executed at the time of starting winning, that is, at the time of winning at the first type starting port 17 (starting winning). In these jobs, various memories stored in the built-in RAM 481 of the main control unit 140 shown in FIG. 16 are used.

  First, as shown in FIG. 17, it is determined whether or not there has been a start prize (S200). As a result, if there is no start prize, the process skips to S250 and confirms whether there is a hold. As a result, when there is no hold (when the number of holds is zero), the process returns to S200, and when there is a hold (when the number of holds is 1 to 4), the process proceeds to S255.

  On the other hand, when there is a start winning, it is determined whether or not the number of pending (unstarted number) exceeds a certain value (“3” in the gaming machine 1) (S210). If the number of reserves (the number of unstarted times) exceeds a certain value, the start winning is invalid and skips to S255. On the other hand, if the number of holdings (the number of unstarted times) does not exceed a certain value, the number of holdings stored in the special symbol holding number memory 481b is increased by 1 (S220).

  Next, a special symbol success / failure determination random number (hereinafter also referred to as a success / failure random number or determination random number) is generated (randomness determination random number generation means) and read (S230). The validity random number generation means may use software or hardware. The read determination random number value is stored in a special symbol success / failure determination random number memory 481a (hereinafter also referred to as a determination random number memory) (S240). In this memory, the read determination random number value is stored in the shift memory format in the time series of the start winning prize.

  Next, the oldest first determination random number value stored in the determination random number memory 481a is read (S255), and the big hit number (winning determination value) is read from the big hit number memory 482a in the ROM 482 (S260). Then, it is determined whether or not the determined random number value matches the jackpot number (S265). As a result, if the two match, the big hit determination is made, and the big hit processing is performed (S270).

  Next, the big hit process (S270) will be described with reference to FIG. First, a jackpot symbol determination random number (identification information determination random number) is generated and read (S280). Then, it is determined whether or not the probability is changed based on the determination random number value read in S230. The probability variation is to improve the probability of success / failure determination (big hit probability) until the next big hit after the end of the special gaming state. Note that it may be determined whether or not the probability is changed using a random number value other than the determination random value. When it is determined that “the probability does not change” (S282: NO), the process proceeds to S284, and the symbols are determined using the tables 1 to 6. Tables 1 to 6 are shown below as [Table 1] to [Table 6], respectively.

  The “appearance rate” in each table indicates the probability of selecting a symbol when determining the jackpot symbol to be displayed using the table. For example, when determining a jackpot symbol using Table 1 ([Table 1]), the probability that “222” is selected as the winning symbol array is 20%, and the probability that “444” is selected is 0%. Is shown.

  Which table is used is determined by a promotion symbol selection process that is periodically started by a timer interrupt after the gaming machine 1 is powered on. FIG. 21 shows a flowchart of the promotion symbol selection process. When this process is activated, it is determined whether a promoted symbol (described later) has been selected and determined (S700). If the promoted symbol has been determined (S700: YES), this process ends. When the promoted symbol has not been determined (S700: NO), the process proceeds to S710, and it is determined whether or not the game ball has already won (start winning) at the first type starting port 17. If the start winning has been completed (S710: YES), this process ends. In S710, it may be determined whether or not the normal symbol actuating gates 36 and 37 are passed (gate passing) instead of the first type starting port 17.

  When the start winning (or passing through the gate) has been completed (S710: NO), it is determined whether or not there is an input to the chance button 8 (S720). At this time, symbols 2, 4, 6, 8, and 0 are displayed on the liquid crystal display device 27 as shown in FIG. 22A, and the player uses the chance button 8 to select a promotion symbol. The chance button 8 includes an A button 8a and a B button 8b as shown in FIG. 22B. Only one of the symbols (2, 4, 6, 8, 0) to be selected by the B button 8b is displayed. Red and other symbols are displayed in blue, where blue is the original color of the even symbol and red is the odd symbol color (corresponding to the mark of the present invention). Are changed in order of 2 → 4 → 6 → 8 → 0 → 2 each time the B button 8b is pressed). Thus, by pressing the B button 8b several times, a desired symbol is displayed in red, and when the A button 8a is pressed, the symbol becomes a promoted symbol. In addition, the symbol that became the promoted symbol remains red. In addition, the screen shown in FIG. 22A disappears once in 30 seconds if no operation is performed, and a normal standby screen is displayed. If the chance button 8 is not input (S720: NO), the promoted symbol selection process is terminated. If there is an input from the chance button 8 (S720: YES), the process proceeds to S730 to execute the promoted symbol determination process.

  FIG. 23 shows the promotion symbol determination process. When this process is activated, it is determined whether or not the symbol selected by the chance button 8 is 4 (the promoted symbol is 4) (S800). When 4 is selected (S800: YES), table 1 is selected (S810), and this process is terminated. If a symbol other than 4 is selected (S800: NO), the process proceeds to S820, and whether the symbol selected with the chance button 8 is 6 (the promoted symbol was 6: the same applies below). Determine. If 6 is selected (S820: YES), table 2 is selected (S830), and this process is terminated. If NO in S820, that is, if a symbol other than 4 or 6 is selected, the process proceeds to S840, and it is determined whether or not the symbol selected by the chance button 8 is 8. When 8 is selected (S840: YES), the table 3 is selected (S850), and this process ends. If NO in S840, that is, if a symbol other than 4, 6, or 8 is selected, the process proceeds to S860, and it is determined whether or not the symbol selected by the chance button 8 is 0. When 0 is selected (S860: YES), the table 4 is selected (S870), and this process ends. If NO in S860, that is, if any of the above symbols, that is, 2 is selected, the process proceeds to S880, the table 5 is selected (S870), and this process ends. Note that the table 6 is selected when a start winning (or passing through a gate) occurs without selecting any symbol (S710: YES).

According to this promotion symbol determination process, when the player selects “4” as the promotion symbol, as shown in Table 1, “444” is not displayed on the liquid crystal display device 27, and “666” is displayed. The probability of being selected is 40%, that is, the probability is selected twice as compared with the case of using the table 6 or the like. Similarly, when the player selects “6” as the promotion symbol, “666” is not displayed on the liquid crystal display device 27, and the probability that “444” is displayed is 40% (see Table 2). . When the player selects any of “2”, “8”, and “0” as the promoted symbols, the jackpot arrangement of the selected symbols, that is, “222”, “888”, and “000” are the liquid crystal display devices. 27, and the probability that “888”, “000”, and “222” are displayed is 40%. That is, regarding the two arrangements of “444” and “666”, the probability that at least one of them is displayed on the liquid crystal display device 27 is constant (here, 40%) regardless of which symbol the player selects as the promoted symbol. ) It should be noted that an array of promotion symbols (for example, an array “444” when the player selects “4” as the promotion symbol) corresponds to the selection array of the present invention. The combination of the arrangement of “444” and “666” is “222”, “444”, “666” by operating the DIP switch 84 (connected to the special symbol control unit 160, see FIG. 5) on the hall side. "888", "888" and "000", "000" and "222" can be changed. When the arrangement to be displayed as the winning symbol is determined in this way, the promoted symbol selection process is terminated (FIG. 21).

  Returning to FIG. When it is determined that “probability is changed” (S282: YES), the process proceeds to S286, and the symbols are determined using the tables 7 to 10. Here, the hole side sets which table is used by the dip switch 86 (see FIG. 5). Tables 7 to 10 are shown below as [Table 7] to [Table 10], respectively.

  The meaning of “appearance rate” in each table is the same as the appearance rate in tables 1 to 6. Table 7 is a standard setting, and every hit arrangement appears evenly. Table 8 is a good setting to select when a hole that has a business form of unlimited when it hits “333” and “777” wants to increase the gross profit. The table 9 is set to display “777” well, and the table 10 is set to increase the possession game, contrary to the table 8.

  As can be seen from the processing of S282 to S286, when the gaming machine 1 has a probability change, “odd odd number” is displayed. ”Is displayed on the liquid crystal display device 27. That is, in the gaming machine 1, the “odd number” symbol is a so-called probability variation symbol, and the “even” symbol is a so-called normal symbol. “Odd numbered lozenges” corresponds to the ascending arrangement of the present invention, and “even numbered (excluding promoted patterns) zodiac eyes” corresponded to the decreasing arrangement of the present invention, and the order of the zodiac eyes (odd, even numbered, or promoted patterns) ) Corresponds to the specific symbol arrangement of the present invention.

  The jackpot arrangement determined by the processing of S282 to S286 is stored in the jackpot symbol determination random number memory 481d (S290). Note that the big hit symbol determination random number is read at the same time as the winning random number at the time of winning the start, but may be read simultaneously with the hit determination or after a predetermined time after the hit determination.

  Next, a reach mode determination random number is generated simultaneously with the jackpot symbol determination random number, and this is read and stored in the reach mode determination random number memory 481k (S295). Further, the determination result of “big hit” (“1” in the gaming machine 1) is stored in the determination result memory 481j (S300).

  The special symbols constituting the jackpot arrangement are displayed in a predetermined arrangement manner after being subjected to a variable display state on the liquid crystal display device 27 based on the special symbol image data stored in the ROM 163 of the special symbol control unit 160. (For example, an arrangement mode of the same three-digit symbol “777”). The special symbol image data is stored in the RAM 481 of the main control unit 140 as an identification information determination value in association with the jackpot symbol determination random number value, and the read jackpot symbol determination random number is compared with the identification information determination value. It is good also as what determines the symbol which stops by doing.

  Furthermore, the reach display mode specified by the reach mode determination random number value is determined after the variable display state is passed to the liquid crystal display device 27 based on the reach display mode image data stored in the ROM 163 of the special symbol control unit 160. Displayed in the reach mode. In this case as well, the reach display mode image data is stored in the reach mode determination value memory 4811l of the RAM 481 of the main control unit 140 as a reach mode determination value in association with the reach mode determination random number value and read. The reach mode to be displayed may be determined by comparing the reach mode determination random number value with the reach mode determination value.

  Next, the detachment process (S310) will be described with reference to FIG. First, it is determined by a random number whether or not an outreach job is performed. Specifically, a reach mode determining random number is generated, read (S315), and the reach number stored in the reach number memory 481i is read (S320). If the reach mode determination random number and the reach number match, it becomes a missed reach job, and if it does not match, it becomes a normal missed job (S330).

  In the case of a miss reach job, at least two special symbols to be aligned (for example, the left symbol and the right symbol among the three types of special symbols) are determined using a miss reach symbol determination random number (S340). Or you may make it match the right design with it referring to the random number of the left design. The determined symbol is stored in the reach symbol number memory 481m (S350). Further, the out-of-line symbol is similarly determined by a random number (S360), and the determined random number value is stored in the out-of-line symbol number memory 481g (S370). Then, the determination result of “outgoing reach” (“2” in the gaming machine 1) is stored in the determination result memory 481j (S380).

  On the other hand, in the case of a normal off-job, each special symbol (for example, left symbol, right symbol, middle symbol) is determined by random numbers, and the determined random number values are stored in the corresponding off symbol number memories 481e, 481f, 481g. (S390 to S440). Further, the determination result of “normally off” (“3” in the gaming machine 1) is stored in the determination result memory 481j (S450).

Next, an outline flow of the special symbol main job executed in the series of the main job will be described with reference to the flowchart of FIG.
First, based on the winning of a game ball at the first type starting port 17, the display of the variation of each special symbol is started on the liquid crystal display device 27 (S500). For example, the left and right and middle symbols are scrolled from top to bottom and from bottom to top.

  Next, the determination result for each winning obtained in the success / failure determination job shown in FIGS. 17 to 19 is read from the determination result memory 481j (S510), and it is determined whether or not the determination result is a big hit determination (S520).

  As a result, in the case of the big hit determination (“1”), the reach mode determining value stored in the reach mode determining value memory 481l corresponding to the above-described reach mode determining random value is read (S580), and the big hit number ( The identification information determination value) is read from the jackpot number memory (determination value storage means) 482a (S600). Next, proceeding to S610, for example, the left symbol and the right symbol are aligned with the same symbol, and after a predetermined reach display mode, the middle symbol is aligned with the same symbol as the left symbol and the right symbol, and is stopped and displayed (S610). ).

  On the other hand, if it is not a big hit determination, it is determined whether or not it is a missed reach determination ("2") (S530). As a result, in the case of the detachment reach determination (“2”), the detachment symbol number is read from the aforementioned detachment symbol number memory 481m, and the detaching symbol number is read from the detaching symbol number memory 481g (S570). Then, a difference between the number of the outreach symbol number and the number of the out-of-interest symbol number (for example, the difference between the left symbol and the middle symbol) is calculated (S571). Determine (S572). For example, when the middle symbol is the symbol immediately before the left symbol and the difference is “−1”, one type is selected from a plurality of types (for example, three types) outliers (for example, a predetermined random number). Can be selected by acquisition) and read. Thereafter, for example, after the left symbol and the right symbol are aligned to the same symbol and subjected to a predetermined reach display mode, the middle symbol is stopped and displayed with a symbol different from the other symbols (S610).

  On the other hand, if it is not outlier reach determination, it is normal outage determination ("3") (S540), each out symbol number is read from outnumber memory 481e, 481f, 481g (S550), and each special symbol (for example, , The left symbol, the right symbol, and the middle symbol) are stopped and displayed at a timing shifted from each other (S560). Even in the case of normal deviation determination, the display mode is changed to various modes by “slip display” or the like. This is because the display mode image data is stored in a normal out display mode determination value memory (not shown) in the RAM 481 of the main control unit 140 as a normal out display mode determination value in association with the reach mode determination random number value. Another example is to determine the normal off mode to be displayed by comparing the read reach mode determining random number value with the normal off display mode determining value.

  When the big hit determination is made, a special symbol is fixedly displayed on the liquid crystal display device 27 in a predetermined arrangement mode (for example, an arrangement mode of the same three-digit symbol “777”), and then a special game is executed. It becomes a gaming state (big hit gaming state). In the special gaming state, first, the opening / closing plate 312 of the big winning device 31 is in an open state, so that the game ball can be easily received by the player in the big winning opening 311. This corresponds to the privilege providing means of the present invention.

  In this special game state, the big winning device 31 is kept in the game ball receiving state until a predetermined end condition is satisfied. For example, when a predetermined time t1 (for example, 30 seconds) elapses or when a predetermined number n1 (for example, 10) of winning balls is detected by the winning ball detection switch 318, the end condition is satisfied, and the game ball receiving state Is ended once, and the opening / closing plate 312 is closed, and one round is completed. If a predetermined continuation condition (passing to a specific area not shown) is satisfied after a predetermined time t2 (for example, 0.5 seconds) has elapsed after the opening / closing plate 312 is closed, the opening / closing plate 312 is again opened. The big winning device 31 enters the game ball receiving state. It should be noted that the game ball receiving state in which the end condition is one round is continuously repeated up to a predetermined maximum number of continuous rounds (16 rounds in the gaming machine 1). Further, if the continuation condition is not satisfied when the end condition is satisfied, the special gaming state ends (so-called puncture) in that round.

  Here, an example of the reach mode determined by the reach mode determination random number generated in S295 is shown. This is characterized by the stop pattern of special symbols. After the three special symbols are temporarily displayed in a selected sequence (that is, a doublet of a promoted symbol) is stopped (temporarily stopped, for example, 0.5 seconds). Then, the variable display is resumed (so-called re-lottery) and stopped at the odd numbered slot (fixed stop). It is only in this temporary stop that the promoted symbols are displayed on the liquid crystal display device 27. This reach mode is seen by the player as “probability changes when a doublet of the promoted symbol is displayed”. Since the promoted symbol was a normal symbol before being selected by the chance button 8, the player has the impression that “the promoted symbol is promoted to a probable symbol”. This is the reason why the symbols forming the selected sequence are called promoted symbols.

  For the hall side, when operating under the LN system, it is necessary to check whether the exchange symbol or the lucky number is displayed every time a big hit is made. Since the symbolic eyes are displayed, it is only necessary to determine whether or not the replacement is necessary only from the lowered arrangement displayed in the fixed stop, and it is not necessary to consider the selected arrangement displayed in the temporary stop, so the determination is easy. It becomes. The promoted symbol is made invalid when a predetermined time (for example, 2 hours) elapses after the gaming machine 1 is turned on. When the promotion symbol becomes invalid, the table used in S284 is fixed to the table 6, and the promotion symbol returns to blue. In other words, even if it is hit with a slot of the promoted symbol, the re-lottery is not performed, and the low probability state is maintained (or the probability is lowered from the probability variation state).

  Next, an example of the reach mode determined not only by S295 but also by the reach mode determination random number generated in S315 will be described. This is an aspect in which the player can freely change the reach design during the reach. The symbol to be changed is stocked at the time of symbol variation or big hit, and is displayed on the liquid crystal display device 27 at the time of stocking and occurrence of the reach mode. An example of the latter is shown in FIG. As shown in the figure, when the reach mode occurs, the screen of the liquid crystal display device 27 is divided into left and right parts, and a reach symbol 76 is displayed below the left region 78, and a “reach symbol” is displayed above it. Please select "message 78 is displayed. In the right area 80 of the screen, symbols 82 stocked up to now are displayed. This figure shows that three kinds of symbols “3”, “7”, and “9” are stocked. In addition, the symbols to be stocked are limited to odd symbols, that is, probability variation symbols. In addition, there are three types of symbols stocked in this figure, but it is determined by the number of symbols stocked when this reach mode occurs, and it becomes 2 to 5 types. Moreover, this mode does not occur when the stocked symbols are 0 to 1 type.

  The player selects a symbol from these stocked symbols using the chance button 8. Specifically, when the B button 8b is pressed, one of the stocked symbols ("7" in this example) is displayed large as shown in FIG. 24 (b), and further displayed when the B button 8b is pressed. The symbol to be changed changes from “7” → “9” → “3” → “7”. When the A button 8a is pressed, the symbol that is displayed at that time is selected (in this example, “7”). The selected symbol is replaced with the reach symbol 76, and the reach mode is continued with the symbol (in this example, “7”). According to this reach mode, it is possible to replace the reach symbol with the probability variation symbol preferred by the player. Note that this mode may be changed so that only normal symbols or probability variation symbols can be replaced. In addition, when changing the normal symbol to the probability variation symbol, it may be possible only when the promotion symbol is reached.

  Separately from the reach mode, an effect operation performed in the liquid crystal display device 27 will be described with reference to a flowchart of FIG. This process is activated in a state where there is a hold. That is, in a state where there is a hold (S800: NO), it is determined whether or not the value of the notification effect determination random number is a predetermined value. The notification effect determination random number value is generated in the same manner as the special symbol success / failure determination random number and the like, and when this is not a predetermined value (S810: NO), this process is terminated. When the value of the notification effect determination random number is a predetermined value (S810: YES), the notification effect character effect means (here, the chance button 8) is validated. Then, a screen as shown in FIG. 26 is displayed on the liquid crystal display device 27. Two angels 63 and 65 in this screen are notification effect characters. The player presses the A button 8a when selecting the left angel 63, and presses the B button 8b when selecting the right angel 65. The mark 67 represents the hold. This figure shows that there are four holds. In subsequent S830, it is determined whether or not the notification effect character effect means (chance button 8) has been operated. When the chance button 8 is operated (S830: YES), it is determined whether or not the hold storage is successful.

  If there is no win (S840: NO), the process proceeds to S850, a hit-notification notification effect is performed, and this process is terminated. The hit notification effect is to display an animation on the liquid crystal display device 27 that an angel selected by the player with the chance button 8 shoots an arrow at any mark 67 but does not hit. When there is a win (S840: YES), the process proceeds to S860, and a lottery for notification is performed to determine whether or not a hit notification effect is performed. This notification lottery is performed using a random number different from the notification effect determination random number value, and the lottery probability varies depending on which angel 63, 65 the player has selected. As a result of this determination, if it is determined that a hit notification is to be made (S860: YES), the process proceeds to S870, a hit notification effect is performed, and this process is terminated. The hit notification effect is to display an animation on the liquid crystal display device 27 that the angel selected by the player with the chance button 8 shoots an arrow at the mark 67 corresponding to the hit hold and hits the mark 67. It is. On the other hand, when it is determined that no hit notification is made (S860: NO), the process proceeds to S850, a hitless notification effect is performed, and the present process is terminated. In this case, the arrow will come off even though there is a hit during the hold.

  If the chance button 8 is not operated even though the image of FIG. 26 is displayed on the liquid crystal display device 27 (S830: NO), the process proceeds to S880 to determine whether the valid timer is 0 or not. If not 0 (S880: NO), the process returns to S830 and waits for the chance button 8 to be operated. Note that the valid timer becomes 0 in 30 seconds after the notification effect process is started (of course, it may be a time other than 30 seconds depending on the specifications of the gaming machine 1). If the valid timer is 0 (S880: YES), the process proceeds to S890, a cancel effect is performed, and this process ends. The cancel effect is to display an animation on the liquid crystal display device 27 that both the angels 63 and 65 in FIG. 26 leave without shooting an arrow.

  As in the gaming machine 1 described above, by providing the control circuit units 171 to 175 of the voice / lamp control unit 170 and the interface units 177 and 178 on different boards, only the interface units 177 and 178 can be exchanged. It becomes. Thereby, for example, when the board surface is changed, the number and color of LEDs controlled by the voice / lamp control unit 170, the type of solenoid, or the like, or the number of LED boards and solenoids is changed. When it is not necessary to change the control circuit units 171 to 175 such as the CPU 171 and the ROM 173 of the sound / lamp control unit 170, only the interface units 177 and 178 can be changed. Therefore, the control circuit units 171 to 175 can be shared among different models, and the control circuit units 171 to 175 can be reused for changing the model. For this reason, it is possible to effectively use resources and reduce costs.

  Furthermore, since the interface units 177 and 178 are separated into the driver unit 177 and the connector output unit 178 and provided on different boards, only the connector output unit 178 can be replaced. As a result, when the number or color of the LEDs, the type of solenoid, or the like is changed, and the driver unit 177 does not need to be changed, only the connector output unit 178 can be changed. it can.

  In the sound / lamp control unit 170, the control circuit units 171 to 175 have a sound control function in addition to the lamp control function. Thereby, the independent board | substrate for a voice control function can be abolished, the number of CPU used as the game machine 1 whole can be reduced, and a structure can be simplified.

  In addition, like the gaming machine 1, by adopting serial communication for communication between the control circuit units 171 to 175 and the interface units 177 and 178 provided on different boards, the control circuit units 171 to 175 and the interface unit 177 are used. 178 can be reduced in number of signal lines. As a result, noise can be reduced, assemblability can be improved, and costs can be reduced.

  As described above, according to the gaming machine 1 described above, it is possible to perform the following services in the hall of the LN business form. That is, in such a hole, the hole side sets the exchange symbols as “4” and “6”, and shows them in a place that is noticeable to the player. That is, if the player hits “444” or “666”, the player must exchange the acquired game ball. Then, since many players think that they do not want to exchange game balls (i.e., want to continue playing with the acquired game balls), the chance button 8 is used to make “4” or “6” a promotion symbol. . As a result, when a symbol is selected using the table 1 or the table 2, it is never displayed on the side of the promoted symbol. Thereby, the player can feel that the game can be advantageously performed.

  The probability that at least one of “4” and “6” is displayed is constant at 40% regardless of which of “2”, “4”, “6”, “8”, and “0” is selected as the promoted symbol (Table 1). Therefore, if the symbols “4” and “6” are used as exchange symbols, the hole side will lose (obtain the player). Absent. Also, the player can actually make a profit. For this purpose, the exchange symbols may be one symbol selected from “4” and “6” and one symbol selected from “2”, “8” and “0”. For example, if the exchange symbol is “2” and “4”, the probability that “444” will be displayed on the liquid crystal display device 27 is 0% when the player changes “4” to the promoted symbol. As a result, the probability of hitting the exchanged symbol under the condition that the probability variation is not performed is 0% + 20% = 20% since “222” is 20% (see Table 1), and the selection sequence was not set. Compared to 40% of cases, the probability actually decreases. The case where the player uses “2” as the promoted symbol is substantially the same, and the probability that “222” is displayed on the liquid crystal display device 27 is 0%, and the probability that “444” is displayed is 20% (table) 5)), the probability that the exchange symbol is hit is 0% + 20% = 20% under the condition that the probability does not change, and the probability actually decreases. Therefore, it is actually advantageous for the player.

  In addition, since the pair of normal symbols (for example, “4” and “6”) whose appearance rate is constant can be changed by the dip switch 84, the hall side can set a favorite exchange symbol. .

  Further, whether or not to change the probability is determined in S282 using the determination random number value regardless of the setting of the promotion symbol, so that the gaming machine 1 can change the probability even if the promotion symbol is set. It does not mean that it will be high. Therefore, it cannot be said that the hole loses because the probability changes too much.

  Further, since the promoted symbol is the same red color as the probability variation symbol, it is possible to prevent the player from having anxiety that “the probability may not vary”. The selection of the promotion symbol is stopped when a game ball enters the first-type start opening 17, so that only the first player of the day is given a privilege of "selecting the promotion symbol", which is a service close to morning. Will be able to. In addition, when two hours have passed since the gaming machine 1 was turned on, the promoted symbol becomes invalid, and this is also a service close to morning.
