Description

  The present invention relates to a slot machine that performs a notification effect of an internal winning combination.

  Conventionally, there is a slot machine that generates a winning combination on the assumption that an internal lottery performed in accordance with the start of a game is won. In order to win a winning combination in such a slot machine, it is not enough that the winning combination is won internally. It is necessary to stop the corresponding symbol on the winning line by operating the stop button with good timing in the game in which the role is won internally. The operation timing of the stop button is not limited to the moment when the winning symbol is displayed on the winning line, but may be within a predetermined time preceding this moment. If the stop button is operated at such timing, the symbol corresponding to the internal winning combination can be drawn and stopped on the winning line by the pull-in control on the slot machine side.

  In the slot machine game as described above, it is extremely advantageous if the internal winning combination can be known in advance. This is because there is a higher possibility that a winning can be achieved by so-called “stopping” that stops the game corresponding to the internal winning combination. Therefore, there is a conventional slot machine that performs a notification effect of an internal winning combination. Furthermore, for the purpose of giving a change to a notification effect that tends to fall into one pattern, a slot machine that performs a notification effect using a character that grows (regresses) as the game progresses has also been proposed (for example, Patent Document 1). reference.). In this slot machine, the notification effect according to the degree of growth of the character is implemented to diversify the frequency and form of the notification effect.

  However, the conventional slot machine has the following problems. That is, in the slot machine that only performs the notification effect of the internal winning combination, as described above, the notification effect tends to fall into a single pattern and may be bored by the player. On the other hand, in the case of a slot machine that performs a notification effect using a character as described above, although the notification effect can be diversified to some extent, there is a possibility that the interest of the game may be reduced according to the player's familiarity.

JP 2002-052120 A

  The present invention has been made in view of the above-mentioned conventional problems, and is intended to provide a slot machine that enhances the fun of games by various notification effects in a slot machine that performs notification effects of internal winning combination. It is.

The present invention includes a symbol variation display means including a plurality of variation display units that variably display a plurality of types of symbols according to a predetermined arrangement in the symbol display area;
Game start operating means operated by the player to start the game;
Internal lottery means for performing an internal lottery for determining an internal winning combination from a plurality of types of combinations in accordance with an operation of the game start operation means and establishing an internal winning flag corresponding to the determined internal winning combination When,
A stop operation means operated by the player to stop the display of variation of symbols in the variation display section;
When the stop operation means is operated, display control means for drawing a symbol corresponding to the established internal winning flag within a predetermined pull-in range and displaying the stop within the symbol display area;
Winning determination means for determining whether or not the symbol that the symbol variation display means stops and displays in the symbol variation area is a predetermined winning symbol;
A flag notification means for notifying the player of the established internal winning flag,
Character selection means operated by a player to select a selected character from a plurality of types of characters,
Parameter storage means for storing a parameter value which is a parameter value corresponding to the selected character;
Auxiliary parameter storage means for storing, for each of the plurality of types of characters, auxiliary parameter values that are calculated with the parameter values in accordance with the establishment of a predetermined condition;
When the predetermined condition is satisfied, a new parameter value is obtained by calculating the auxiliary parameter value stored in the auxiliary parameter storage unit for the selected character and the parameter value, and the parameter value is stored in the parameter storage unit as the parameter value. Parameter calculating means for storing,
In the predetermined arrangement of the specific variation display portion which is at least one of the variation display portions, it is impossible to aim for winning at the same time because the corresponding symbols are separated by a predetermined number or more, and In the internal lottery means, a role set that is a set of roles having a relationship of not winning an internal winning at the same time in one game is set,
In the slot machine, the flag notification means is configured to selectively perform notification of an internal winning flag of a group role that is a role belonging to the role set with a probability according to the parameter value. (Claim 1).

  In the slot machine of the present invention, each time the predetermined condition is satisfied, the parameter value and the auxiliary parameter value are calculated to obtain a new parameter value, and the parameter value may gradually vary. The flag notification means notifies the internal winning flag of the group combination with a probability according to the parameter value. Here, the group set that is a set of the group combinations has a relationship that it is impossible to simultaneously win a prize in the specific variation display unit, and the internal lottery means does not simultaneously win an internal winning. A set of roles. If the internal winning flag corresponding to such a group combination is notified, it is possible to perform a so-called eye stop that aims at the corresponding symbol in the specific variation display unit, which is extremely advantageous for the player side.

  In the slot machine, a player's favorite character can be selected as the selected character from a plurality of types of characters having different auxiliary parameter values. Therefore, in the slot machine, the degree of variation of the parameter value differs depending on the type of the selected character selected by the player, and the notification frequency of the internal winning flag differs. In other words, in the slot machine, the notification frequency of the internal winning flag can be changed according to the type of the selected character selected by the player, and gambling and game play can be adjusted to some extent.

  As described above, according to the slot machine of the present invention, the degree of variation of the parameter value can be changed according to the type of the selected character selected according to the player's preference, and the frequency of occurrence of the notification effect of the internal winning flag can be changed. Can change. That is, in the slot machine, the notification effect of the internal winning flag is various, and the interest of the game is improved.

  As the calculation performed by the parameter calculation means in the slot machine of the present invention, various calculations for obtaining the new parameter value using the parameter value and the auxiliary parameter value can be used. For example, in addition to addition, subtraction, multiplication, and division, an operation that selectively combines these may be used.

The slot machine according to the present invention may be a slot machine in a narrow sense using medals or coins as a game medium, or a parrot (R) using a pachinko ball as a game medium.
Further, the predetermined condition may be changed for each character, and a common one may be set for the plurality of types of characters.
Further, the flag notifying unit may be configured such that the selected character such as a person or an animal displayed on a display screen such as a liquid crystal display notifies the internal winning flag.

In addition, as the predetermined condition, any one of a plurality of types of specific combinations included in the plurality of types of combinations is set,
The auxiliary parameter storage means stores auxiliary parameter values for each of the plurality of types of specific roles,
The internal lottery means is preferably configured to be able to simultaneously determine two or more specific combinations of the plurality of types of specific combinations as an internal winning combination in one game (claim 2).

  In this case, for example, when the player knows that two or more types of specific combinations have been won simultaneously by notification by the flag notification means, the parameter value depends on which specific combination is awarded. Auxiliary parameter values to be calculated can be selected. The participation factor that the degree of change of the parameter value can be changed according to the player's will increases, and the interest of the game can be enhanced.

Further, the parameters corresponding to the selected character are set for a plurality of types of the set of roles, and the auxiliary parameter storage means sets auxiliary parameter values for the sets of characters for the types of characters. It is preferable to memorize (claim 3).
In this case, the notification frequency of the internal winning flag changes for each role set, and the notification effect of the internal winning flag is further diversified.

In addition, the flag notification means is configured to perform false notification that the internal winning flag of the group combination is established when the internal winning flag of the group combination is not established,
It is preferable that the false notification regarding the group combination is selectively performed with a probability corresponding to the parameter value.

  In this case, it is possible to produce a player's disappointment according to the occurrence of the false notification. According to this feeling of disappointment, it is possible to give further relief to the notification effect of the internal winning flag. In particular, for example, when a specific person, animal, or the like is set as the character, it is expected that the interest of the player will be transferred to the selected character in response to the false notification, and the interest of the game can be improved.

In addition, there is provided setting value setting means for selectively setting one of a plurality of setting values having different degrees of advantage on the player side, and the flag notification means notifies the internal winning flag of the group combination. The probability is preferably different for each set value (claim 5).
In this case, even if the internal winning probability of each combination in the internal lottery means is not changed, by changing the notification probability by the flag notification means, there is a difference in the degree of advantage on the player side for each set value. Can be provided.

  In addition, as a slot machine that can set a height difference in the payout rate (one of the indicators indicating the player's advantage), which is the ratio of the number of payouts to the number of game media input, an internal winning of at least one of the roles A slot machine in which probabilities are set in stages is common. The current rules regarding the type approval test for slot machines require an approval test for each stage of setting the internal winning probability, and the burden of the type approval test is excessive. On the other hand, when the notification probability of the internal winning flag is changed according to the set value as described above, it is possible to change the substantial payout rate without changing the internal winning probability of each combination. Therefore, in the slot machine in which the notification probability of the internal winning flag is changed for each set value, it is possible to avoid the necessity of undergoing the type certification test for each set value, and the test burden can be reduced. Furthermore, in a slot machine with a constant internal winning probability, a payout rate similar to that of a slot machine with a high setting value is realized even if the setting value is low, as long as the established internal winning flag can be linked to a winning. obtain. Therefore, according to this slot machine, it is possible to make the player feel a sense of expectation regardless of whether the set value is good or not, and to increase gambling.

The embodiment of the present invention will be specifically described with reference to the following examples.
Example 1
This example is an example related to the slot machine 1 that performs the notification effect of the internal winning combination. The contents will be described with reference to FIGS.
As shown in FIGS. 1 and 2, the slot machine 1 of this example includes three symbol display portions 21 (hereinafter referred to as reels 21) that display a plurality of types of symbols 20 in a symbol display area 110 in accordance with a predetermined arrangement. Depending on the operation of the start lever 62, the symbol variation display means 2 provided, the game start operation means 62 (hereinafter referred to as the start lever 62) operated by the player to start the game, and The internal lottery for determining the internal winning combination is performed from among the internal lottery means 42 for establishing the internal winning flag corresponding to the determined internal winning combination, and the change display of the symbol 20 on the reel 21 is stopped. And a stop operation means 61 (hereinafter referred to as a stop button 61) operated by the player, and when the stop button 61 is operated, Display control means 45 that draws a symbol corresponding to the symbol within a predetermined pull-in range and stops it in the symbol display area 110, and a symbol 20 that the symbol fluctuation display means 2 stops and displays in the symbol fluctuation area 110 has a predetermined value. A winning determination means 49 for determining whether or not a winning symbol is present, and a flag notification means 47 for notifying a player of the established internal winning flag are provided.

  The slot machine 1 includes a character selection means 43 operated by a player to select a selected character displayed at the time of a game effect from three types of characters, and a parameter value that is a parameter value corresponding to the selected character. Parameter storage means 340 for storing, and auxiliary parameter storage means for storing, for each of the three types of characters, auxiliary parameter values that are calculated with parameter values in accordance with the winning combination (predetermined conditions) of specific combination A to specific combination D When 330 and any of the specified combination A to specified combination D wins, a new parameter value is obtained by calculating the auxiliary parameter value and the parameter value stored in the auxiliary parameter storage unit 330 for the selected character, and the parameter storage Parameter calculation means 46 to be stored in the means 340 as the parameter value; It is provided.

In this slot machine 1, it is impossible to aim for winning at the same time because the corresponding symbols are separated by a predetermined number of symbols or more in a predetermined arrangement of the specific variation display portion which is at least one of the reels 21. In addition, in the internal lottery means 42, a set of roles, which is a set of roles exhibiting a relationship that internal winnings cannot be made simultaneously in one game, is set.
The flag notification unit 47 selectively performs notification of the internal winning flag of the group combination belonging to the combination set with a probability corresponding to the parameter value.
In this example, as the calculation performed by the parameter calculation unit 46, a calculation for adding an auxiliary parameter value that can take a positive or negative value to the parameter value is set.
Hereinafter, this content will be described in detail.

  First, the playability of the slot machine 1 of this example will be described. The slot machine 1 has a game property that the selected character acquires “special skills” as the game progresses, and the “acquisition level” gradually changes. As “special skills”, three types of “special skills” are set, which respectively correspond to a bell role set, a plum role set, and a cherry role set. In the slot machine 1 of this example, the internal winning flag corresponding to the group role belonging to the corresponding role set is selectively notified with a predetermined probability corresponding to the “acquisition level” of the “special skill” by the selected character. . In the slot machine 1 of this example, “special skill” corresponds to the parameter, and “acquisition level” corresponds to the parameter value. Further, in the slot machine 1, a selected character can be selected from three types of characters according to the player's preference. In this slot machine 1, the notification frequency of the internal winning flag can be changed according to the type of the selected character, and the gameability and gambling can be adjusted to some extent.

  The combination of the slot machine 1, the internal winning combination, and the winning combination will be described with reference to FIGS. In FIG. 3, the names of the respective roles are shown in the left column, the winning symbols that are combinations of the symbols 20 corresponding to the respective roles are shown in the middle row, and the benefits to be given to the player side by winning are shown in the right column. In the slot machine 1 of this example, a bonus combination, three types of combination, four types of specific combination, and a replay combination are set. As the three types of role sets, a bell role set, a plum role set, and a cherry role set are set. Bell roles A to C are set as group roles belonging to the bell role set, plum roles A to C are set as group roles belonging to the plum role set, and cherry roles A to C are set as group roles belonging to the cherry role set ing. Specific combinations A to D are set as the four types of specific combinations. The specific combination A to C is a winning combination that can be won only in the normal gaming state, while the specific combination D is a winning combination that can be won only in the bonus game. In the slot machine 1, an internal winning combination by the internal lottery means 42 becomes an internal winning combination. When winning symbols corresponding to the internal winning combination are arranged along the winning line, the winning combination becomes a winning combination.

  For the bell roles A to C, which are group roles belonging to the bell role set, only symbols to be stopped in the symbol display area 110L corresponding to the left reel 21L are defined, and symbols corresponding to other reels 21 are optional. ing. The symbol that should be stopped and displayed in the symbol display area 110L differs depending on the type of bell combination. The symbols corresponding to the bell roles A to C are “white bell”, “hatching bell”, and “black bell”, respectively. As will be described in detail later, the specific variation display portion for the bell role set is the left reel 21L.

  For the plum roles A to C which are group roles belonging to the set of plum roles, only symbols to be stopped in the symbol display area 110C corresponding to the middle reel 21C are defined, and symbols corresponding to other reels 21 are optional. ing. The symbols to be stopped in the symbol display area 110C differ depending on the type of plum combination. The symbols corresponding to the plum roles A to C are “white plum”, “hatched plum”, and “black plum”, respectively. As will be described in detail later, the specific variation display portion for the plum role set is the middle reel 21C.

  For the cherry roles A to C which are group roles belonging to the cherry role set, only symbols to be stopped in the symbol display area 110R corresponding to the right reel 21R are defined, and symbols corresponding to other reels 21 are optional. ing. The symbols that should be stopped in the symbol display area 110R differ depending on the type of cherry. The symbols corresponding to the cherry roles A to C are “white cherry”, “hatched cherry”, and “black cherry”, respectively. As will be described in detail later, the specific variation display portion for the cherry role set is the right reel 21R.

  Next, the slot machine 1 of this example has an external configuration as shown in FIG. In the slot machine 1, the front portion facing the player is formed by a front frame body 10 having a substantially rectangular symbol display window 11 provided substantially at the center. The front frame 10 includes a liquid crystal display unit 530, a pair of left and right speakers 520, and a lamp unit 560 on the upper side of the symbol display window 11. The front frame 10 has a base 100 that forms the base of the slot machine 1 below the symbol display window 11.

  As shown in FIG. 2, the base portion 100 is formed so as to protrude relatively toward the player with respect to the symbol display window 11 located behind the player. The base unit 100 has a table-like operation surface 14 at the upper end adjacent to the symbol display window 11, a medal tray 15 for paying out medals at the lower end, and an operation panel 13 below the operation surface 14. Have.

  As shown in FIGS. 1 and 2, the operation surface 14 has a bet button 64 for betting a credited (stored) medal, a credit settlement button 65 for paying out a credited medal, and a bet on a game. A medal insertion slot 630 for inserting medals is arranged. On the operation panel 13, a start lever 62 for starting the symbol variation of the reel 21, a stop button 61 for stopping the symbol variation, and a character selection button 430 for selecting the selected character are arranged. .

  As shown in FIGS. 1 and 2, the bet button 64 is a bet button for setting 3 bets as a maximum bet as the number of bets. The bet button 64 generates a 3-bet signal representing the bet number 3. When the credit is less than 3, the bet button 64 generates a 2-bet signal or a 1-bet signal according to the credited number.

  As shown in FIGS. 1 and 2, the start lever 62 is an operation lever that generates a game start signal, which is a control signal for the reel 21, at a timing when the player operates. In the slot machine 1, the start lever 62 is set to the valid state when a medal is directly inserted or when three medals are bet by operating the bet button 64.

  The stop button 61 is an operation button that is generated at a timing when a player operates a variable stop signal that is a control signal of the reel 21. The stop button 61 of this example is a combination of a left stop button 61L corresponding to the left reel 21L, a middle stop button 61C corresponding to the middle reel 21C, and a right stop button 61R corresponding to the right reel 21R.

  The character selection button 430 is an operation button constituting the character selection means 43 as shown in FIGS. By pressing the character selection button 430, the player can select a favorite selected character. In the character selection means 43 of this example, the selected character can be changed in the order of character A → character B → character C → character A every time the character selection button 430 is pressed.

  The liquid crystal display unit 530 includes a liquid crystal display as shown in FIGS. The liquid crystal display unit 530 displays various effect screens that produce games as the game progresses. In the slot machine 1 of this example, the selected character displayed on the liquid crystal display unit 530 performs notification of the internal winning flag.

  As shown in FIG. 2, the symbol display window 11 is a display window including symbol display areas 110L, C, and R. According to the symbol display window 11 in which three symbol display areas 110 each displaying three symbols are arranged in parallel, nine symbols 20 arranged in a two-dimensional matrix of 3 rows and 3 columns can be displayed. The portion corresponding to each symbol display area 110 in the symbol display window 11 is formed of a transparent resin plate so that the symbol 20 can be seen from the player side. For nine symbols 20 arranged in a two-dimensional matrix, winning lines 111 to 115, which are the arrangement direction of symbols to be awarded, are set. The winning lines include horizontal winning lines 111 to 113 and diagonal winning lines 114 and 115.

  On the right side of the symbol display window 11, a credit display unit 551 and a payout number display unit 552 are arranged. The credit display unit 551 is a display unit that digitally displays the number of medals credited (stored) by the credit function. The payout number display unit 552 is a display unit that digitally displays the number of payout medals at the time of winning.

  On the back side of the symbol display areas 110L, C, and R, as shown in FIGS. 1, 2, and 4, reels 21L, C, and R constituting the symbol variation display means 2 are respectively arranged. Each of the reels 21L, C, and R is a rotary reel having a substantially cylindrical shape and a plurality of types of symbols 20 arranged on the outer peripheral surface thereof at a substantially constant interval. Each reel 21L, C, R has a reference position piece (not shown) at one reference position in the rotation direction. The reference position piece is a detected piece that is detected by a reference position detection unit 66 described later. The reel 21 may be an image-type reel that displays the symbols on the liquid crystal display in place of the rotary reel of this example.

  As described above, in the slot machine 1 of the present example, the specific variation display unit is different for each role set. The specific change display portions corresponding to the bell role set, the plum role set, and the cherry role set are a left reel 21L, a middle reel 21C, and a right reel 21R, respectively. Here, the reason why the left reel 21L is the specific variation display part of the bell combination set will be described.

  As shown in FIG. 4, in the left reel 21 </ b> L, three types of symbols “white bell”, “hatching bell”, and “black bell” corresponding to the bell roles A to C are arranged at every 7 symbols. Although described in detail later, the pull-in control range by the display control means 45 of this example is equivalent to 4 symbols. On the other hand, the number of symbols simultaneously displayed in the symbol display area 110L is three symbols. For example, in order to draw and stop the “hatching bell” of symbol number 10, symbol numbers 10 to 12 are displayed in the symbol display region 110L from the moment when symbol numbers 4 to 6 are displayed in the symbol display region 110L. It is necessary to operate (stop operation) the stop button 61L within a variation range of 7 symbols up to the moment.

  On the other hand, in order to draw and stop the “white bell” of the symbol number 17, the symbol numbers 17 to 19 are displayed in the symbol display region 110 L from the moment when the symbol numbers 11 to 13 are displayed in the symbol display region 110 L. It is necessary to perform stop operation within the fluctuation range of 7 symbols up to the moment. Further, in order to pull in and stop the “black bell” of symbol number 3, symbol numbers 3 to 5 are displayed in the symbol display region 110L from the moment when symbol numbers 18 to 20 are displayed in the symbol display region 110L. It is necessary to perform stop operation within the fluctuation range of 7 symbols up to the moment.

  Thus, in the left reel 21L, the range of the stop operation for stopping the symbols “white bell”, “hatching bell”, and “black bell” in the symbol display area 110L is independent, and two or more bell roles There is no overlapping range that can be aimed at winning. That is, the left reel 21L serves as the specific variation display unit that cannot simultaneously aim for winnings of two or more group roles belonging to the bell role set. As in the case of the bell combination, the middle reel 21C serves as the specific variation display unit for the plum combination, and the right reel 21R serves as the specific variation display unit for the cherry combination.

Next, the slot machine 1 of this example has a mechanical configuration as shown in FIG.
A control board 3 for controlling the overall operation of the slot machine 1 and each part electrically connected to the control board 3 will be described with reference to FIGS. For the control board 3, in addition to the above-described configuration, the inserted medal detection unit 63 for detecting a medal inserted as a game medium, the reel 21 together with the reel 21, and the rotation of the reel 21 constituting the symbol variation display means 2. A reference position detecting unit 66 for detecting a position, a medal paying unit 54 for paying out medals, a lamp control board 56 for controlling lighting of the lamp unit 560, a setting value operating unit 68 for setting a setting value representing the player's advantage degree, a speaker A voice control board 52 for controlling 520 (voice output part), various display parts 55 such as a credit display part 551 and a payout number display part 552, and a liquid crystal control board 53 for controlling the liquid crystal display part 530 are electrically connected. Has been.

  As shown in FIGS. 1 and 2, the inserted medal detection unit 63 is a detection unit that outputs an insert signal each time a medal is inserted from the medal insertion port 630. In the slot machine 1 of this example, when a medal is inserted through the medal insertion slot 630 or when a medal is bet according to the operation of the bet button 64, the start lever 62 is set to an effective state. The game can be started.

  The reel drive unit 22 is means for driving the reel 21 to rotate. As shown in FIG. 1, the reel driving unit 22 includes a stepping motor (not shown) that can be controlled in units of steps, and rotationally drives the reel 21 by the rotational driving force of the stepping motor. The stepping motor rotates one step each time a control pulse is taken from the control board 3.

As shown in FIG. 1, the reference position detector 66 is a detector that detects the passage of the reference position piece for each of the reels 21L, 21C, and R and outputs a detection signal.
As shown in FIG. 1, the medal payout unit 54 is configured to pay out a predetermined number of medals to the medal tray 15 under the control of the control board 3.
As shown in FIG. 1, the set value operation unit 68 is an operation unit for changing a set value for setting an internal winning probability of a bonus combination or the like step by step using a setting key 680.

  As shown in FIGS. 1 and 2, the control board 3 includes a CPU 31, ROM 33 and RAM 34 as memory means, and an I / O unit 32 as an input / output interface. The ROM 33 has a function as auxiliary parameter storage means 330 that stores auxiliary parameter values corresponding to characters. The RAM 34 has a function as parameter storage means 340 that stores parameter values corresponding to characters.

  As shown in FIG. 1, the ROM 33 as the memory means stores a winning random number table used by the internal lottery means 42 for the lottery of the internal winning combination. As shown in FIG. 5, the winning random number table is a data table that defines winning random numbers for each winning combination. FIG. 5A shows a winning random number table applied to the normal state. FIG. 5B shows a winning random number table applied to the bonus game. Each winning random number table is a random number table that defines winning random numbers for one type of combination or combinations of two or more types that can be internally won in one game. In the slot machine 1 of this example, a winning random number table for each set value is set.

  Here, as can be seen from FIG. 5A, in the slot machine 1 of this example, three types of group roles (bell role A to C, plum role A to C, or cherry role A belonging to any one of the role sets are provided. For ~ C), the winning random numbers are all independent. For example, the random number range of 218-7500, which is the winning random number of the bell role A, the random number range of 19,200-26482, which is the winning random number of the bell role B, and the random number range of 41600-46281, which is the winning random number of the bell role C They are independent of each other and do not have duplicate winning random numbers. Therefore, in the slot machine 1 of this example, two or more of the group roles belonging to the same set of roles are not simultaneously won in one game.

  Further, as can be seen from FIG. 5A, in the slot machine 1 of this example, 55000 to 55140 is set as a winning random number that can cause the specific combination A and the specific combination B to be simultaneously won internally, and is specified as the specific combination B. 56300 to 56452 are set as winning random numbers that can simultaneously win the combination C. On the other hand, in the slot machine 1 of this example, the specific combination A and the specific combination B, or the specific combination B and the specific combination C are set so as not to win simultaneously in one game. Therefore, in a game in which two or more types of specific combinations A to C are simultaneously elected internally, simultaneous winning is impossible, but a player may aim for any specific combination. it can.

  As shown in FIGS. 1 and 2, the ROM 33 stores a stop table (not shown) used for stop control of the reel 21. The stop table is a data table that defines the number of drawn symbols (number of smooth frames) for each symbol arranged on the reel 21. The number of drawn symbols represents the variable number of symbols until the reel 21 is actually stopped when the stop button 61 is operated at the moment when the corresponding symbol is positioned on the winning line 112.

  Further, as described above, the ROM 33 has a function as auxiliary parameter storage means 330 that stores auxiliary parameter values to be added to parameter values. As shown in FIG. 6, the auxiliary parameter storage unit 330 stores a parameter variation table in which auxiliary parameter values for each character are defined. FIG. 6A shows a parameter variation table applied to the character A. FIG. 6B shows a parameter variation table applied to the character B. FIG. 6C shows a parameter variation table applied to the character C.

  In the parameter variation tables of FIGS. 6A to 6C, auxiliary parameter values corresponding to “special skills 1 to 3” are specified for specific roles A to D, respectively. For example, the auxiliary parameter value of “special skill 1” when the specific combination C wins is 2 for character A, 80 for character B, and −50 for character C. Similarly, the auxiliary parameter value of “special skill 1” when the specific combination B wins is 10 for character A, 1 for character B, and 2 for character C. Here, as described above, in the slot machine 1 of this example, the specific combination A and B, and the specific combination B and C may be internally won simultaneously in one game. When two or more types of specific combinations are won simultaneously, an auxiliary parameter value to be added to the parameter value can be selected according to which specific combination is won by the player.

  As described above, the RAM 34 as the memory means has a function as the parameter storage means 340 for storing the parameter value indicating the “skill level” of the “special skill” by the selected character selected by the player, as shown in FIG. Yes. The parameter storage means 340 stores parameter values corresponding to “special skills 1 to 3”, which are three types of “special skills”, for the selected character. The parameter storage unit 340 stores the parameter value calculated by the parameter calculation unit 46.

  The CPU 31 executes a software program read from the ROM 33, thereby extracting a random number extraction means 48 for extracting random numbers, a winning determination means 49 for determining a winning symbol, a display control means 45 for controlling the symbol variation display means 2, an internal winning An internal lottery means 42 for lottering a combination, a flag control means 41 for controlling an internal winning flag, a parameter calculating means 46 for calculating a parameter value corresponding to the selected character, and a flag notifying means 47 for notifying the establishment of the internal winning flag. It is comprised so that each function of may be implement | achieved.

  As shown in FIGS. 1 and 2, the random number extraction means 48 is a means for extracting random numbers from a predetermined range of random numbers generated by a random number generation means (not shown). The random number extraction means 48 of this example extracts a random number using the change start signal of the start lever 62 as a trigger signal and inputs it to the internal lottery means 42. Note that the random number generation means of this example generates an integer in the range of 0 to 65535 in decimal numbers as a random number for internal lottery.

  As shown in FIG. 1, the internal lottery means 42 is a means for determining an internal winning combination by internal lottery and establishing a corresponding internal winning flag. The internal lottery means 42 determines the internal winning combination by collating the random number extracted by the random number extracting means 48 against the winning random number of each winning specified in the winning random number table shown in FIG.

  As shown in FIG. 1, the flag control means 41 is a means for controlling an internal winning flag representing a state where each winning combination can be won. The flag control means 41 starts the next game regardless of whether or not the internal winning flag other than the bonus flag which is the internal winning flag of the bonus combination is won in the game in which the internal winning flag is set for the first time. Switch to the off state before By such control of the flag control means 41, all the combinations other than the bonus combination that has not won a prize in the internally won game are missed. On the other hand, the bonus flag is carried over to the next game until winning.

  As shown in FIGS. 1 and 2, the display control unit 45 is a unit that controls symbol variations of the reels 21 </ b> L, C, and R via the reel driving unit 22. The display control means 45 starts the symbol variation of the reel 21 in response to the game start signal and stops the symbol variation of the reel 21 in response to the variation stop signal. The display control means 45 inputs a control pulse to the reel drive unit 22 and rotates the stepping motor by one step for each pulse. The display control means 45 counts the number of control pulses input to the reel drive unit 22, that is, the number of steps rotated by the stepping motor. In particular, in this example, the number of steps generated after the latest detection signal can be counted by resetting the number of steps to zero each time the detection signal of the reference position piece is fetched for each reel 21.

  As shown in FIG. 1, the display control means 45 performs so-called pull-in control in which symbols within a pull-in control range determined by rules (rules regarding game machine authorization, type verification, etc.) are stopped on the winning line. In this example, a range corresponding to four symbols is set as the pull-in control range. The display control means 45 calculates a bita symbol, which is the symbol 20 instantaneously located on the winning line 112, based on the number of steps at the time of taking in the fluctuation stop signal, and compares the bitter symbol with the stop table. . Then, the number of drawn symbols defined corresponding to the bitter symbol is acquired, and the reels 21 are stopped by drawing the symbols for the number of drawn symbols.

  As shown in FIGS. 1 and 2, the winning determination means 49 is a means for determining whether or not the combination of symbols stopped and displayed on the three reels 21L, 21C, 21R is a predetermined winning symbol. Specifically, the winning determination means 49 determines whether or not the combination of symbols stopped on the winning lines 111 to 115 set so as to cross the three reels 21L, 21C, 21R is a winning symbol. And determine the winning combination. The winning determination means 49 takes in the number of steps counted by the display control means 45 for each stepping motor of the reel drive unit 22 after each reel 21L, C, R stops. The winning determination means 49 obtains the type of the symbol 20 stopped on the winning lines 111 to 115 based on the number of steps, and determines whether or not a winning combination is established for the combination of the symbols 20. The winning determination means 49 outputs a medal payout number (see FIG. 3) according to the type of winning combination to the medal payout unit 54.

  As shown in FIGS. 1 and 6, the parameter calculation means 46 is a means for calculating a parameter value in accordance with any winning combination of specific roles A to D. When any one of the specific combinations A to D wins, the parameter calculation means 46 acquires an auxiliary parameter value corresponding to the specific combination that won the prize by referring to the parameter variation table (FIG. 6), and adds it to the parameter value. As auxiliary parameter values and parameter values, there are three types of auxiliary parameter values or parameter values respectively corresponding to “special skills 1 to 3”. The parameter value calculated by the parameter calculation means 46 is restricted to a range of 0-100. When the parameter value exceeds 100, 100 is forcibly set, and when it is less than zero, zero is forcibly set.

  As shown in FIGS. 1 and 7, the flag notification unit 47 is a unit that notifies the establishment of the internal winning flag corresponding to the group combination belonging to the combination by lottery. In particular, the flag notification unit 47 of this example is configured to display a selection character selected by the player on the liquid crystal display unit 530 to notify the internal winning flag. The flag notification means 47 selectively notifies the internal winning flag with a notification probability corresponding to the “acquisition level” (parameter value) of the “special skill” by the selected character selected by the player. As described above, the flag notification means 47 notifies the internal winning flag of the bell role A, B, C with the notification probability corresponding to the “acquisition level” (parameter value) of “special skill 1”, and “special skill 2” Announcement of the internal winning flags of plums A, B, and C with the notification probability according to the “acquisition level” (parameter value), and the cherry role with the notification probability according to the “acquisition level” (parameter value) of “special skill 3” A, B, and C internal winning flags are notified.

  The probability that the flag notification means 47 of this example implements the notification effect is set as in the group combination notification lottery table of FIG. The group combination notification lottery table is a table showing the relationship between the parameter value indicating the “acquisition level” of the “special skill” by the selected character and the notification probability of the internal winning flag corresponding to the group combination. As described above, “special skill 1” corresponds to the bell role set, “special skill 2” corresponds to the plum role set, and “special skill 3” corresponds to the cherry role set.

  As is known from FIG. 7, basically, the notification probability of the internal winning flag increases as the “acquisition level” (parameter value) of “special skill” increases. Therefore, basically, the notification probability of the internal winning flag can be increased by repeating the winning of the specific combination. However, for “special skill 2”, the peak value (100%) of the notification probability is set in the range of “acquisition level” 80 to 89, and when the “acquisition level” approaches 100, the notification probability decreases. In the slot machine 1 of this example, by including the setting of the notification probability such as “special skill 2”, an unexpected notification effect rich in change is realized.

  Next, the operation of the slot machine 1 of the present example configured as described above will be described with reference to FIGS. FIG. 8 is a flowchart showing a rough flow of a game executed by the slot machine 1. FIG. 9 is a flowchart showing the flow of the character selection process P1. FIG. 10 is a flowchart showing the flow of the game start process P2. FIG. 11 is a flow showing the flow of the winning process P3. As shown in FIG. 8, the slot machine 1 of this example executes a game by processing a character selection process P1, a game start process P2, and a winning process P3 in this order.

  In the character selection process P1 as shown in FIG. 9, first, the operation of the character selection button 430 is determined as in step S101. When the character selection button 430 is operated, the currently set character type is determined. If character A is currently set (step S102), character B is set as the selected character (step S103). If character B is currently set (step S112), character C is set as the selected character (step S113). If character A and character B are not currently set (steps S102 and S112), character A is set as the selected character (step S122).

  Next, the flow of the game start process P2 will be described with reference to FIG. As in step S201, the operation of the start lever 62 is determined. When the start lever 62 is operated, the internal winning combination is determined by lottery (step S202), and the internal winning flag of the winning winning combination is set to 1 (ON state) (step S203). Subsequently, as in step S204, the flag state of the internal winning flag (bell flag) for the bell role is determined.

  When any one of the bell flags is 1 (on state), as in step S205, a notification lottery for determining whether or not to notify the bell flag according to the acquisition level (parameter value) of the special skill 1 is performed. . Subsequently, as in step S206, the flag state of the internal winning flag (plum flag) of the plum role is determined. When any one of the plum flags is 1 (on state), as shown in step S207, a notification lottery for determining whether or not to notify the plum flag according to the skill level (parameter value) of the special skill 2 is performed. Is done.

  Subsequently, as in step S208, the flag state of the internal winning flag (cherry flag) for the cherry role is determined. When any one of the cherry flags is 1 (on state), as shown in step S209, a notification lottery for determining whether or not to notify the cherry flag according to the skill level (parameter value) of the special skill 3 is performed. Is done. When winning by the notification lottery in steps S205, S207, and S209, notification of the type of winning combination corresponding to the established internal winning flag is started (step S210), and rotation of the reel 21 is started (step S211). .

  Next, the flow of the winning process P3 will be described with reference to FIG. In step S301, a stop operation for the left reel 21L, that is, a press operation of the left stop button 61L is determined. When the left stop button 61L is pressed, the left reel 21L is stopped as in step S302. In step S321, a stop operation on the middle reel 21C, that is, a depression operation of the middle stop button 61C is determined. When the middle stop button 61C is pressed, the middle reel 21C is stopped as in step S322. In step S331, a stop operation for the right reel 21R, that is, a press operation of the right stop button 61R is determined. When the right stop button 61R is pressed, the right reel 21R is stopped as in step S332. As in step S303, the above process is repeatedly performed until all the reels 21L, C, and R are stopped.

  After all the reels 21 are stopped (step S303), it is determined whether or not the combination of symbols stopped on the winning line as shown in step S304 is a winning symbol (see FIG. 3), thereby determining a winning combination. The When the replay combination is won as in step S305, a replay game is set for the next game (step S306). When the bonus combination is won as in step S345, the bonus flag is reset to the off state (zero) (step S346), and the bonus game flag is set to the on state (1) (step S347).

  When the specific combination is won as in step S355, the auxiliary parameter value is added to the parameter value representing the acquisition level of each special skill as in step S356, and a new parameter value is obtained. Then, this new parameter value is stored in the parameter storage means 340 (step S357), and thereafter a medal payout process P31 is performed. When the replay combination, bonus combination, and specific combination do not win (steps S305, S345, S355) and other small combination wins (step S365), a medal payout process P31 is performed.

  In step S307, it is determined whether or not the bonus game end condition has been achieved. If the bonus game end condition is achieved, the bonus game flag is reset to the off state (zero) (step S308). If the bonus game end condition is not achieved, the internal winning flag other than the bonus flag is reset to the off state (zero) (step S309), and the notification effect is ended (step S310).

  As described above, according to the slot machine 1 of this example, the degree of change in the parameter value varies depending on the type of the selected character selected according to the player's preference, and the notification frequency of the internal winning flag can change. In other words, in this slot machine 1, there are various notification effects such as the notification frequency of the internal winning flag changing according to the player's selection, and the interest of the game is improved.

  It should be noted that a false notification that the internal winning flag is established may be performed even when the group combination belonging to the combination is not internally won. In this case, similarly to the real notification performed when the internal winning flag is established, the false notification ratio can be determined according to the “skill level” of the “special skill”.

  Further, the setting value of this example set via the setting value operation unit 68 represents the setting stage of the internal winning probability such as a bonus combination. Instead of this, a setting value indicating the setting stage of the notification probability of the internal winning flag of the group combination belonging to the combination set may be employed. Furthermore, it is also possible to set a combination of an internal winning probability setting step and an internal winning flag notification probability setting step that can be set independently of each other.

Further, in this example, as shown in the parameter variation table (FIG. 6), the auxiliary parameter value added to the parameter value according to the winning of the specific combination is constant. Alternatively, the auxiliary parameter value may be changed over time, or when a specific winning combination is won, a lottery is performed to determine whether or not to change the value of the auxiliary parameter value. The value of may be varied.
Furthermore, in this example, as the calculation of the parameter value and the auxiliary parameter value, the addition of the auxiliary parameter value to the parameter value is set. However, instead of this, another calculation can be adopted.

  In addition, in this example, the winning of the specific role is set as the predetermined condition, but instead of this, the winning in the lottery performed for each game, the winning of the replay role for 3 consecutive games, and the mini game in the game Achievement or the like can be set as the predetermined condition.
