Furthermore, the sub-control unit 91 detects an operation on the production switch 56, and controls the display of images on the liquid crystal display 51 and the sound output from the speakers 53 and 54 in accordance with the detected operation.

When playing a game in the slot machine 1, the player sets a prescribed number of bets by inserting medals into the medal inserting section 4 or operating the MAXBET switch 6. As a result, the winning line LN becomes valid, and the operation of the start switch 7 becomes valid, making it possible to start the game. The winning line LN is a line for determining whether the combination of symbols on the reels 2L, 2C, and 2R displayed on the transparent window 3 matches the combination of winning symbols. In this embodiment, only the winning line LN set across the middle row of the reel 2L, the middle row of the reel 2C, and the middle row of the reel 2R, that is, the symbols arranged horizontally in the middle row, is defined as the winning line. , a plurality of winning lines may be provided. Further, an invalidation line may be provided to make it easier to recognize that the combination of symbols constituting a winning prize has been aligned on the winning line LN.

When the start switch 7 is operated in a state where the game can be started, the reels 2L, 2C, and 2R rotate. At this time, the main control unit 41 performs an internal lottery. The internal lottery is a process of determining symbol combinations (display result combinations) that are allowed to be derived. When a symbol combination is allowed to be derived through an internal lottery, it is also said that the winning combination corresponds to the symbol combination.

When the stop switches 8L, 8C, and 8R are operated, the rotation of the reel corresponding to the operated stop switch is stopped. As a result, the symbol combination is derived and displayed on the transparent window 3. When a symbol combination that matches the symbol combination of a winning combination stops on the winning line LN, a winning corresponding to the winning combination occurs.

In the reel stop control, the rotation of the reels 2L, 2C, and 2R corresponding to the operation is stopped within the maximum stop delay time (in this embodiment, 190 ms (milliseconds)) from the time when each stop switch is operated. Control is performed to stop it. Reels 2L, 2C, and 2R are rotated 80 times per minute, and the symbols are varied by 80 (rotations) x 20 (number of symbols per reel, for example, 20 symbols) = 1600 symbols, so the maximum Until the stop delay time (190ms) elapses, a maximum of four symbols can be drawn in. In other words, in the stop control, one symbol is selected from the symbol displayed when the stop switches 8L, 8C, and 8R are operated, and the symbol up to 4 frames ahead, for a total of 5 frames (pull-in range). It is possible to select and derive the reels 2L, 2R, and 2R.

The winning combinations include a special winning combination (bonus), a small winning combination, and a replay winning combination. A special winning combination (bonus) is a winning combination in which the gaming state is controlled to a bonus state in which the probability of winning a small winning combination is higher than in a non-bonus state. The special bonuses include first-class special bonuses such as RB (regular bonus) and BB (big bonus), and second-class special bonuses such as CB (challenge bonus). In this embodiment, CB is provided as a special combination. A small role is a role in which a medal is awarded by winning a prize. A replay winning combination is a winning combination that allows the player to start the next game without consuming medals owned by the player.

In order to win a prize for each role determined according to the gaming state, it is necessary to win the internal lottery and set the winning flag for that role. In the internal lottery, the main control unit 41 determines whether or not to allow winnings for each of the above-mentioned winning combinations before the display results of all the reels 2L, 2C, and 2R are derived (specifically, the start switch 7 (at the time of detection) using random numbers.

Of the winning flags for each role, the winning flags for small roles and replay roles are valid only in the game in which the flags were set, and will be invalid in the next game, but the winning flags for special roles are It is valid until the combination of combinations allowed by the flag is completed, and becomes invalid in a game where the combination of combinations allowed by the flag is completed. In other words, once a special winning flag is won, even if it is not possible to match the combination of winnings allowed by the flag, that winning flag will not be invalidated and will be carried over to the next game. ing.

In addition, in the internal lottery, when the stop operation is performed in a predetermined operation mode (for example, operation order, operation timing), the small winning combination becomes more advantageous than when the stop operation is performed in other operation modes. It is possible to win a winning combination or a re-playing combination (hereinafter also referred to as a "push order combination"). For example, the push order combination may include a combination in which when a stop operation is performed in a predetermined operation mode, the stop mode is more advantageous than the stop mode when the stop operation is performed in another operation mode. , including combinations in which when a stop operation is performed in a predetermined operation manner, the rate of stopping is higher in a more advantageous stop operation than when the stop operation is performed in another operation manner. Further, the advantageous stopping mode includes not only a stopping mode that involves the awarding of medals, but also a stopping mode that involves a transition to an advantageous gaming state, a stopping mode that avoids a transition to a disadvantageous gaming state, and the like.

The main control unit 41 performs an advantageous section transfer lottery to determine whether to control the advantageous section when predetermined lottery conditions are established in the normal section (hereinafter also referred to as "normal section normal"). By doing so and winning the relevant advantageous section transition lottery (hereinafter also referred to as "advantageous section winning"), control of the advantageous section is started. The advantageous section is a section in which navigation information corresponding to the operation mode of the stop switches 8L, 8C, and 8R can be reported. On the other hand, the normal section is a section in which navigation information corresponding to the operation mode of the stop switches 8L, 8C, and 8R cannot be reported.

The main control unit 41 is capable of executing a navigation system that notifies the player of the operation modes of the stop switches 8L, 8C, and 8R that are advantageous to the player when the player wins the push order combination in the internal lottery. Specifically, the main control unit 41 provides a navigation system that notifies, as navigation information, the operation mode of the stop switches 8L, 8C, and 8R that is advantageous for the player according to the internal lottery result by the lighting mode of the game auxiliary display 12. It is possible to control the assist time (AT) which is a notification period during which notification can be executed.

During the advantageous section, the main control unit 41 executes navigation notification by controlling the AT when winning the push order combination, and determines the operation modes of the stop switches 8L, 8C, and 8R that are advantageous for the player ( For example, the order of operations, operation timing, etc.) are notified using the game auxiliary display 12, and the navigation information , a navigation effect is executed to notify the user of the operation mode using the liquid crystal display 51 or the like.

The push order combination includes a push order bell in which a bell is won when the player's operation mode matches the operation mode corresponding to the winning push order winning combination (hereinafter also referred to as "correct procedure"), and a push order bell that wins the prize when the player's operation mode matches the operation mode corresponding to the winning push order combination (hereinafter also referred to as "correct procedure"). This includes push-order reps in which the replay wins when the mode matches the operation mode corresponding to the winning push-order combination. Hereinafter, navigation that can be performed in a game where the push order bell is won will also be referred to as bell navigation.

By operating the stop switches 8L, 8C, and 8R according to the correct procedure according to the bell navigation, the player can win the winning combination that pays out more medals among the winning combinations included in the push order bell. Alternatively, by operating the stop switches 8L, 8C, and 8R according to the correct procedure according to the bell navigation, the player can win a winning combination that is unlikely to be missed out of the winning combinations included in the push order bell. In addition, among the roles included in the push order bell, the role that can win when the stop switches 8L, 8C, and 8R are operated in the correct answer procedure is called the "main character", and the stop switch 8L, The winning combinations that can be won when 8C and 8R are operated are also referred to as "secondary winnings."

By operating the stop switches 8L, 8C, and 8R in the operation mode notified by the navigation notification and navigation performance, it is now possible to securely win the main character included in the push order winning combination in the internal lottery. It has become. Furthermore, in controlling the advantageous section, the advantageous section LED 19 is turned on to notify that the advantageous section control is being performed.

[Game state transition]
FIG. 3 is a diagram for explaining the transition of gaming states. As shown in FIG. 3, the gaming states controlled by the liquid crystal display 51 include non-internal and internal.

Inside, the game is in a state where the game can be played and the payout rate of medals based on a predetermined design value is guaranteed. Note that in the slot machine 1 of this embodiment, most of the games are played by the player inside the slot machine 1.

On the other hand, when the player is not inside the game, the player does not play a game, or even if the player plays a game, the time for playing the game is extremely short. In non-internal mode, when a CB is won and the winning of the CB is missed, the gaming state shifts to internal mode from the next game. In other words, the internal state is such that the winning of CB has been carried over. Once the gaming state is internally controlled, it is rare for the carried over CB to win, and even if it does, the probability is extremely low.

In addition, in the example shown in FIG. 3, CB is not shown as a gaming state, but if a CB is won during non-internal or internal, the game will be changed from non-internal or internal to CB. The state changes. In this case, the CB ends after approximately one game, and the gaming state shifts to non-internal mode again.

The internal state includes a normal section and an advantageous section. As described above, the advantageous section is a section in which navigation information corresponding to the operation mode of the stop switches 8L, 8C, and 8R can be reported. On the other hand, the normal section is a section in which navigation information corresponding to the operation mode of the stop switches 8L, 8C, and 8R cannot be reported. In the normal section, when the winning section is won in the advantageous section transfer lottery (advantageous section winning), the state is controlled to be the advantageous section.

The states in the advantageous section include normal times (hereinafter also referred to as "advantageous section normal") and AT (hereinafter also referred to as "advantageous section AT"). Advantageous section is usually a state in which navigation can be performed. The advantageous section AT is a state in which the navigation execution probability is higher than the normal advantageous section. In this embodiment, the navigation execution probability in the normal advantageous section is 0%, but the navigation may be executed with a predetermined probability.

Further, the net increase in the number of games that the player can obtain per game in the advantageous section AT is larger than the net increase in the number of games that the player can obtain per game during the normal advantage section and the normal period. The net increase per game (hereinafter also referred to as "1G net increase") is the number of medals paid out per game minus the number of medals used to set the number of bets per game. .

The net increase in a predetermined state (normal section normal, advantageous section normal, advantageous section AT) is the total number of medals paid out in a predetermined state (normal section normal, advantageous section normal, advantageous section AT) in the predetermined state ( This is the number obtained by subtracting the total number of medals used to set the number of bets in the normal section normal, advantageous section normal, and advantageous section AT).

In both the normal section normal and the advantageous section normal, medals decrease. The advantageous section AT is a state in which the number of medals increases. The advantageous section AT is a state that is more advantageous to the player than the normal section normal and the advantageous section normal. Specifically, in this embodiment, the 1G net addition number is designed to be -1 in the normal section normal and the advantageous section normal, and the 1G net addition number is designed to be 8 in the advantageous section AT. .

That is, the ball payout rate in the normal section normal and the advantageous section normal is less than 1, and the ball payout rate in the advantageous section AT is greater than 1. Further, the ball payout rate is the same between the normal section and the advantageous section. Here, the payout rate is the ratio of the total number of medals paid out to the total number of medals used to set the number of bets during a period controlled to a certain state.

If the advantageous section is won in the normal normal section, the advantageous section will be controlled as normal. Advantageous Section Normally, if AT is won, control is made to the advantageous section AT. When the advantageous section AT ends, the advantageous section is normally controlled when continuation control is performed, and the normal section is normally controlled when end control is performed. Further, when end control is performed in the normal advantageous section, control is performed in the normal section.

The main control unit 41 is capable of executing termination control and continuation control. End control is performed when control to an advantageous state that is advantageous to the player (in this embodiment, advantageous section AT) ends in an advantageous section, or when a predetermined end condition is satisfied in a normal advantageous section. This is the control to end the control to the advantageous section. Continuation control is control that continues control to an advantageous section when control to an advantageous state (advantageous section AT) ends in the advantageous section.

When the control to the advantageous section AT or the advantageous section normal is terminated by the termination control, the control to the advantageous section is terminated. In this case, the next game will be controlled to the normal section (normal section normal). At that time, information regarding advantageous sections is deleted. The information regarding the advantageous section includes information such as the number of games played in the advantageous section, the number of net additions during the advantageous section, and the number of net additions during the advantageous section AT.

End control is performed when a limiter condition or any end condition is satisfied in an advantageous section (advantageous section normal or advantageous section AT), or when an end condition corresponding to the net increase is established at the end of advantageous section AT (described later). etc. is executed. Further, termination control is also executed when initialization is performed by changing settings. If end control is not performed at the end of advantageous section AT, continuation control is performed.

For example, the limiter conditions include that the number of games played in an advantageous section reaches a predetermined specific number (1500G), or that the net increase in the number of coins in an advantageous section reaches a predetermined specific number (2400). . Further, for example, the arbitrary ending condition includes playing the predetermined upper limit number of games without winning an advantageous win in the advantageous section normal.

If you win the advantageous section transfer lottery during the normal section, you will be controlled again to the advantageous section. In this embodiment, the number of games to be played in the normal section is designed to be approximately one (for example, the winning probability in the advantageous section transfer lottery is designed to be 90% or more). By doing this, in most cases, the advantageous section is won in the first game in which control to the normal section is started, and the control is again controlled to the advantageous section (advantageous section normal) from the next game.

When the advantageous section is normally controlled again after the end control is performed, the information regarding the advantageous section is initialized and counting of the number of games played in the advantageous section is started. Further, in this case, the main control unit 41 cannot grasp the net increase in number when the control was performed in the previous advantageous section AT.

On the other hand, when the control to the advantageous section AT is completed by continuous control, the control to the advantageous section is continued and the advantageous section is normally controlled. Furthermore, in this case, since control to the advantageous section continues, information regarding the advantageous section is not initialized. In other words, the main control unit 41 can continue to count the number of games played in the advantageous section and grasp the net increase in the number of games played during the previous control in the advantageous section AT.

FIG. 4 is a block diagram showing the configuration of the slot machine. As shown in FIG. 4, the slot machine 1 includes a game control board 40 that controls the progress of the game and outputs various commands according to the progress of the game, and a performance control board 40 that controls predetermined performances according to the commands. 90, a power supply board 101 that generates power to drive electrical components, and an external output board 1000 that outputs signals according to the progress of the game to the outside.

The game control board 40 advances the game based on detection signals from switches such as various operation means and detection means (examples shown on the left side of the game control board 40 in FIG. 4), Display devices such as those shown on the left side of the board 40 are driven and controlled. Moreover, the game control board 40 drives and controls the reel motors 32L, 32C, and 32R based on signals from the reel sensors 33L, 33C, and 33R.

The game control board 40 is equipped with a circuit configuration such as a main control section 41 (exemplified in the game control board 40 in FIG. 4). The main control unit 41 performs processing related to the progress of the game, and directly or indirectly controls the components mounted on or connected to the game control board 40.

[Winning role]
FIG. 5 is a diagram for explaining types of winning combinations, symbol combinations of winning combinations, and awards at the time of winning. The name column in FIG. 5 shows the name of the winning combination, and the symbol combination column shows the combination of symbols that will result in the winning combination. In addition, in the symbol combination column that can stop on the invalid line, symbol combinations that can be easily recognized by the player and that can stop on the invalid line when a winning symbol combination stops on the winning line are listed. It is shown. The award column shows the value that will be awarded at the time of winning (number of medals paid out, replay award, etc.).

As shown in FIG. 5, a CB is provided as a special combination. The small prizes are middle bell, upper bell 1 to 8, watermelon, and cherry. As a replay combination, a reply is usually provided.

The middle bell is a role corresponding to the main character mentioned above. Upper bells 1 to 8 are winnings corresponding to the above-mentioned secondary winnings, and the number of coins paid out is smaller than that of the middle bell. Specifically, if the middle bell is won, 11 coins will be paid out, and if the upper bells 1 to 8 are won, two coins will be paid out. If a watermelon wins, the watermelon symbols will line up on reels 2L, 2C, and 2R.

[Lottery target role]
FIG. 6 is a diagram for explaining combinations of winning combinations that are read out as lottery target combinations for each gaming state. The role number column in Figure 6 shows the role number determined for each lottery target role, the lottery target role column shows its name, and the winning combination combination column shows the role numbers included in each lottery target role. The combinations of winning combinations to be drawn are shown, and in the gaming state column, for each gaming state, a circle mark indicates that the winning combination is to be drawn.

As shown in FIG. 6, CB is provided as a lottery target winning combination for the special winning combination. The small winning combinations to be drawn include 6-option bells 1 to 6, watermelon, and cherry. As a lottery target role for the re-gaming role, a reply is usually provided. Note that watermelon and cherry are also referred to as "rare combinations" because their winning probability in the internal lottery is lower than that of the 6-choice bell.

In the non-internal mode, all the winning combinations are possible, but in the internal mode, only CB cannot be won because the winning of CB has already been carried over.

[Reel control of push order]
FIG. 7 is a diagram for explaining reel control at the time of winning a push order combination. As shown in FIG. 7, six selection bells 1 to 6 are provided in the pressing order. In a game in which a 6-option bell is won during AT (during advantageous section AT), BellNavi is executed and the correct answer procedure is notified to the player. The player can win a winning combination that is advantageous to the player by operating the stop switches 8L, 8C, and 8R in the correct procedure according to the BellNavi.

For example, in a game where any of the 6-choice bells 1 to 6 wins, when stop switches 8L, 8C, and 8R are operated in the correct answer procedure, the main middle bell wins and 11 pieces are paid out. , when the stop switches 8L, 8C, and 8R are operated in the incorrect answer procedure, either the upper bell, which is a secondary role, wins and two coins are paid out, or the prize is lost.

[Setting value]
In the slot machine 1 of this embodiment, the payout rate of medals changes depending on a set value. Specifically, the payout rate of medals is changed by determining the winning probability used in the internal lottery according to the set value. The set value is comprised of six levels from 1 to 6, with 6 being the highest payout rate, and decreasing values in the order of 5, 4, 3, 2, and 1, the lower the payout rate. That is, when 6 is set as the setting value, the advantage is the highest for the player, and as the value decreases in the order of 5, 4, 3, 2, and 1, the advantage gradually decreases.

To change the setting value, operate the power switch on the power box provided inside the slot machine 1, and if the power of the slot machine 1 is turned on, turn it off once, and then change the setting. It is necessary to turn on the power of the slot machine 1 after operating the key switch and turning on the setting key switch. When the setting key switch is turned on to turn on the power of the slot machine 1, the slot machine 1 shifts to a setting change state in which it is impossible to proceed with the game on condition that the door is open. When the setting change state is entered, the current setting value read out from the RAM 41c is displayed on the setting value display as a display value.

In the setting change state, when the reset/setting switch is operated, the display value displayed on the setting value display is updated one by one (if the setting is further operated from setting 6, it returns to setting 1). Thereafter, when the start switch 7 is operated, the displayed value is determined as the set value. When the setting key switch is turned off, the determined display value (setting value) is stored in the RAM 41c, and the game enters a state in which the game can proceed. Note that the setting change state is entered by turning the power switch once to the OFF state, turning the setting key switch to the ON state, and turning on the power switch, so these operations are also collectively referred to as setting change operations.

When the settings are changed, the information regarding the game stored in the RAM 41c is initialized. Therefore, for example, if the setting is changed during an advantageous section, information regarding the advantageous section is initialized and control is made to the normal section. In this case, as described above, the main control unit 41 will no longer be able to grasp the net increase in number when it was controlled in the previous advantageous section AT.

[About type test]
The slot machine 1 is capable of outputting external output signals indicating the gaming status, error occurrence status, and the like. These external output signals are output from the game control board 40 under the control of the main control unit 41, and are sent to the hall computer or the It is designed to be output to an external device such as a data display terminal installed corresponding to the slot machine 1.

Furthermore, the slot machine 1 is configured to be able to externally output signals used for type testing. In the industry where gaming machines such as slot machines are distributed, inspection by a third-party organization (type test) is mandatory before shipment, and only those machines that are determined to meet the specified standards in the type test are There are special circumstances in which shipping to amusement arcades is permitted.

The slot machine 1 includes an input/output board for inputting and outputting signals used for testing. The input/output board is electrically connected to the game control board 40 and the performance control board 90. The test signals output from the slot machine 1 to the test device include a game start signal for starting the game, such as setting the bet amount and rotating the reels, and a game start signal for ending the game, such as stopping the reels. This includes an end signal, a signal that allows the number of coins to be paid out to be specified, and the like.

The input/output board mounted on the slot machine 1 includes a connector for electrically connecting to the game control board 40, a connector for electrically connecting to the production control board 90, and an electrically connecting to the testing device. A connector is provided for this purpose. The type test is performed by inputting and outputting various signals with the input/output board and the test device connected through a connector. When the slot machine 1 outputs a test signal, the test signal is input to the test device via the input/output board. This allows the test device to specify the number of games played in the slot machine 1, the number of bets set, the number of medals paid out, and the like.

As described above, information is repeatedly input and output between the slot machine 1 and the test device via the input/output board, and the game can be automatically played repeatedly. As a result, the type test for the slot machine 1 can be automatically performed.

[Standards for type test]
FIG. 8 is a diagram for explaining the type test criteria. Type examinations are conducted for the purpose of regulating gaming machines that are likely to significantly arouse the desire for gambling. As shown in FIG. 8, tests including a short time test, medium short time test, medium time test, and long time test are conducted as the type test. In the table shown in FIG. 8, the "number of games executed" indicates the prescribed number of games executed in each test, and the "upper limit value" indicates the upper limit value of the ball payout rate. The payout rate is the ratio of the total number of medals paid out to the total number of medals used to set the number of bets during a period in which a predetermined number of games are played.

In each test, if the ball output rate exceeds the upper limit as a result of playing the prescribed number of games, the machine falls under the category of a gaming machine that is likely to significantly arouse the desire for gambling, and will not pass the type test. In this way, the type test eliminates slot machines that are likely to seriously arouse the desire for gambling.

For example, if the control to the advantageous section AT, which is advantageous to the player, ends, and after a short period of time has elapsed, the control is continued to the advantageous section AT for a long period of time, the ball payout rate will exceed the above-mentioned upper limit. , an excessive amount of medals will be paid out in a short period of time. In such a case, the desire for gambling will be greatly aroused, and the control will be unintentionally continued in the advantageous section AT. In view of the above-mentioned circumstances, in the present embodiment, the slot machine 1 is configured so as to prevent the slot machine 1 from being unintentionally continuously controlled to the advantageous section AT.

As shown in FIG. 8, the short-time test is a test of 400 games (hereinafter also referred to as "G"). The upper limit of the ball payout rate in this test is 220%. A 1600G test is performed for medium and short time tests. The upper limit of the ball payout rate in this test is 150%. The medium time test is a 6000G test. The upper limit of the ball payout rate in this test is 125%. The long-term test is conducted at 17,500G. The upper limit of the ball payout rate in this test is 115%.

In this embodiment, the prescribed number of bets required to execute one game is three. For example, in a short-time test, if the number of bets for each game is set to 3 and the game is executed for 400G, the total number of medals used to set the number of bets will be 1200. Here, if a player wins the middle bell, which is an 11-card combination, in all games, the total number of medals to be paid out will be 400G x 11 medals = 4400 medals. In this case, the ball output rate is 1200 sheets/4400 sheets = 367%, which exceeds the upper limit of the ball output rate of 220%, and therefore does not pass the type test.

In this embodiment, the design is such that the net increase in the number of 1G cards is eight in the advantageous section AT, which is an advantageous state. In the above example, if you win the middle bell, which is an 11-card hand in all games, the number of coins paid out (11 coins) - the number of bets (3 coins) = 8 coins, so the net increase in 1G will be 8 coins. Become. However, if the advantageous section AT continues for 400G, the ball delivery rate will be 367%, which exceeds the upper limit (220%), so the type test cannot be passed.

Therefore, in order to pass the type test, it is necessary to limit the number of games controlled in the advantageous section AT in 400G that are continuously executed. For example, in 400G that are executed continuously, the number of games controlled in the advantageous section normal is controlled to 220G, and the number of games controlled in the advantageous section AT (normal section normal or advantageous section normal) is controlled to 180G. Suppose we did.

Assume that the net number of 1G cards added in 220G, which is normally controlled in the advantageous section, is 0, and the net number of 1G cards added in 220G, which is controlled in the advantageous section AT, is 8. In this case, the number of bets for each game is set to 3 and the game is executed for 400G, so the total number of medals used to set the number of bets is 1200.

Also, the total number of medals paid out in the normal advantageous section of 220 games is 660 pieces (=220G x 3 pieces), and the total number of medals paid out in the advantageous section AT of 180 games is 1980 pieces (=180G x 11 pieces). Therefore, the total number of medals paid out with 400G is 2640 (660+1980). In this case, the ball output rate is 2640 pieces/1200 = 220%, which matches the upper limit value (220%) of the ball output rate, and therefore passes the type test.

In the above example, the number of medals (net increase) that increases in the advantageous section AT of 180 games is the total number of medals paid out (11 medals x 180G = 1980 medals) - total number of bets (3 medals x 180G = 540 medals) = 1440 medals. becomes. In other words, in the above example, if the number of games controlled by the advantageous section AT is 180G or less (net increase of 1440 sheets or less), the type test is passed, but if the number of games controlled by the advantageous section AT is 180G or less, the type test is passed. If the number exceeds 1,440 sheets, the model test will not be passed.

[Example of transition of net increase during advantageous period]
FIG. 9 is a diagram for explaining an example of a transition in the number of net increases during an advantageous section. In the example described above, the net increase in 1G in the 220G normally controlled advantageous section is 0, and the net increase in 1G in the 180G controlled in the advantageous section AT is 8.

In the example shown in FIG. 9, similarly, an example will be described in which 220G control is performed normally in the advantageous section, and then 180G control is performed in the advantageous section AT. In this embodiment, it is assumed that the number of 1G net additions is -1 in the advantageous section normal, and the number of 1G net additions is eight in the advantageous section AT.

In FIG. 9(a), the vertical axis shows the number of net additions, and the horizontal axis shows the number of executed Gs. As shown in FIG. 9(a), when the advantageous section is normally controlled and the 220th G is completed, the net increase in number is -220 (=-1 x 220G). Then, it is assumed that the vehicle is controlled to the advantageous section AT from the 221st G. In 180G from the 221st G to the 400th G, the net increase is 1440 sheets (=8 sheets x 180G). As a result, after 400G has passed, the net increase in number is 1220 (=1440-220).

In the example explained earlier, if the net increase is 0 in the 220G advantageous section normal, and the 1G net increase is 8 in the 180G advantageous section AT, the net increase will be 1440 after 400G has passed, and as a result, It reaches the upper limit of 220% for short-term tests. However, if the net increase in 1G is -1 in the normal advantageous section, it will decrease by 220 in the normal advantageous section, so the net increase will remain at 1220 after 400G, which is the upper limit of the short-term test (220% ) will never be reached.

However, the example in Figure 9(a) explains the case where the number of net additions changes on average, and in reality, stochastic variations occur, so there is no reason why the number of net additions changes like this. isn't it.

For example, as shown in FIG. 9(b), suppose that in the case where the advantageous section is normally controlled, the winning combination with a large number of payouts (for example, an 11-card winning combination) happens to be consecutively won. As a result, if the number of sheets is increased by 80, the net increase will be -140 after 220G. As a result, after 400G has passed, the net increase in number is 1300 (=1440-140). However, even in such a case, the upper limit value (220%) of the short-time test is not reached.

In the example explained earlier in which the number of 1G net additions is 0 in the normal advantageous section, if even a slight stochastic variation as shown in Figure 9(b) occurs, the upper limit of the short-term test (220%) will be exceeded. This will result in However, as shown in Figure 9, if the 1G net increase is set to -1 in the normal advantageous section, even if stochastic variations occur, the upper limit of the short-time test will be exceeded. The probability of such cases occurring can be reduced as much as possible.

[AT winning rate, number of AT acquired, and rate of reaching 2400 coins]
As explained above using FIGS. 8 and 9, when trying to design the net increase in number of cards to 8 in the advantageous section AT, setting an upper limit (for example, 180G) to the number of games that can be controlled in the advantageous section AT, After ending the advantageous section AT, it is desirable to control to a non-advantageous section AT in which the net increase in 1G is negative (for example, -1 sheet) in a predetermined period (for example, 220G).

Based on the above, the slot machine 1 in this embodiment was designed as follows. As described above, when the control to the advantageous section AT is completed, the main control unit 41 performs either continuation control or termination control. If continuous control is performed, the advantageous area is normally controlled by ending the control to the advantageous area AT. In other words, control to the advantageous section continues.
In this case, information regarding the advantageous section is not initialized, and information such as the number of net additions during the previous advantageous section AT control and the number of net additions during the advantageous section is retained.

On the other hand, when the end control is performed, the control to the advantageous section AT ends and the control is then carried out to the normal section (normal section normal). Then, after being controlled to the normal section for about one game, when the control is again performed to the advantageous section (advantageous section normal), the information regarding the advantageous section is initialized. As a result, information such as the number of net additions during the previous advantageous section AT control and the number of net additions during the advantageous section will be erased.

In the present embodiment, when the normally controlled start operation for the 1st G in the advantageous section is performed, the lottery for the number of AT winning games and the lottery for the number of AT acquisition coins are performed. The main control unit 41 determines the number of AT winning games by lottery in the AT winning game number lottery.

When the number of AT winning games has elapsed since the advantageous section was controlled normally, the advantageous section AT is won. For example, if 220G is determined as the number of AT winning games, the advantageous section will be controlled normally, then the advantageous section AT will be won in the 220th G (AT winning game), and the next game will be controlled to the advantageous section AT. become. Winning to the advantageous section AT may be determined when an operation to start the AT winning game is performed. Other details of the AT winning game number lottery will be described later using FIG. 14. Note that the present invention is not limited to this, and an AT lottery may be performed every game to determine whether or not to win the advantageous section AT.

In addition, the main control unit 41 determines the number of AT acquisitions by lottery in the AT acquisition number lottery. The number of AT acquired medals is the number of medals to be increased from when the control to the advantageous section AT ends until the control to the advantageous section AT ends. The main control unit 41 determines the number of AT games to be given when controlling the advantageous section AT based on the number of AT acquisitions.

For example, suppose that it is decided to increase the number of medals by 480 in the AT acquisition number lottery. In this embodiment, the net increase in the number of 1G medals in the advantageous section AT is 8, so if it is decided to increase the number of medals by 480 medals, the number of AT games will be 60G (=480 medals/ 8 pieces) will be awarded. Other details of the AT acquisition number lottery will be described later using FIG. 15.

In this embodiment, the percentage of winning in the advantageous section AT (hereinafter also referred to as "AT winning rate") is determined according to the number of games played after the advantageous section is normally controlled (hereinafter also referred to as "number of elapsed games"). ) are designed differently.

For example, during a period when the number of games played after being controlled normally in the advantageous section is between 201G and 250G, the ratio of being controlled by the advantageous section AT is higher than during a period when the number of played games is between 1G and 200G. (AT winning rate is high). In other words, in the AT winning game number lottery, the rate at which one of 201G to 250G is determined is higher than the rate at which any one of 1G to 200G is determined.

In addition, in this embodiment, depending on the number of games played from the time when the advantageous section is normally controlled until winning the advantageous section AT, the control to the advantageous section AT ends after being controlled to the advantageous section AT. The number of medals that increases by the time (AT acquired number) and the rate at which the increase in medals reaches 2400 medals in the advantageous section (the limiter condition due to the number of net increases is met) (hereinafter also referred to as "2400 medal attainment rate") Designed differently. A detailed explanation will be given below using FIG. 10.

FIG. 10 is a diagram for explaining the AT winning rate, the number of AT acquisitions, and the rate of reaching 2400 coins. As shown in FIG. 10, when continuous control is performed, during the period when the number of elapsed games is 1G to 200G, the AT winning rate is X11, the number of AT acquired coins is Y11, and the rate of reaching 2400 coins is Z11. In the period when the number of elapsed games is 201G to 250G (hereinafter also referred to as the "first period"), the AT winning rate is X12, the number of AT acquired coins is Y12, and the rate of reaching 2400 coins is Z12. In the period where the number of elapsed games is 251G to 300G (hereinafter also referred to as the "second period"), the AT winning rate is X13, the number of AT acquired coins is Y13, and the rate of reaching 2400 coins is Z13. .

On the other hand, when termination control is performed, during the period in which the number of elapsed games is 1G to 200G, the AT winning rate is During the period, the AT winning rate is X22, the number of AT acquired is Y22, and the rate of reaching 2400 coins is Z22.In the second period, the AT winning rate is X23, the number of AT acquired is Y23, and the rate of reaching 2400 coins is Z22. , the rate of reaching 2,400 sheets is Z23.

In this embodiment, X11>X21, Y11<Y21, Z11<Z21, X12>X22, Y12<Y22, Z12<Z22, Designed so that the following relationships hold: >Y12, Z11>Z12, X13<X12, Y13>Y12, Z13>Z12, X21<X22, Y21>Y22, Z21>Z22, has been done. A more specific explanation is as follows.

After the control to the advantageous section is terminated by the end control, the period from when the control is again controlled to the advantageous section until the 200G (hereinafter also referred to as "specific number of games") is played is the first after the said period has passed. The rate of control in the advantageous section AT is lower than in the period (201G to 250G) (X21<X22). By doing so, it is possible to significantly reduce the desire for gambling, and it is also possible to prevent medals from being paid out excessively in a short period of time. Note that the period is not limited to the first period (201G to 250G) described above, and may be a period that includes all games after 201G.

In addition, when one set value is set, the first period (from 201G to 250G) is higher than the ratio of control in the advantageous section AT in the second period (251G to 300G) after the first period has elapsed from the specific timing (X22>X23). By doing this, players will be motivated to continue playing until they play a specific number of games, and it will be difficult for players to end the game as control to the advantageous section AT ends, so the operating rate of slot machines at game parlors will increase. can be improved.

Here, the first setting value is, for example, setting 6. Further, settings 4 to 6 may be used. In this embodiment, as will be described later, the pattern in which the net increase number changes is designed to vary depending on the set value. Note that the period is not limited to the second period (201G to 250G) described above, but may be other periods (for example, 301G to 350G).

In addition, when the first setting value is set, in the first period (201G to 250G) from the specific timing (timing when 200G is played) when the specific number of games (200G) is played after continuous control is performed. The rate controlled by the advantageous section AT is the first period (201G to 250G) from the specific timing (timing when 200G is played) when the specific number of games (200G) is played after the control to the advantageous section is finished by the end control. ) is higher than the ratio controlled by the advantageous section AT (X12>X22). By doing so, the player can expect that continuous control will be performed to continue control to the advantageous section.

Here, the first setting value is, for example, setting 6. Further, settings 4 to 6 may be used. Note that the period is not limited to the second period (201G to 250G) described above, but may be other periods (for example, 301G to 350G).

In addition, after the control to the advantageous section is finished by the termination control, the period from when the control is re-controlled to the advantageous section until the specific number of games (200G) is played is after the continuation control is performed and the specific number of games is played. The rate of control in the advantageous section AT is lower than in the period up to (X21<X11). By doing so, it is possible to significantly reduce the desire for gambling, and it is also possible to prevent medals from being paid out excessively in a short period of time.

Furthermore, when the control to the advantageous section AT is decided in the first period, the expected value of the number of medals to increase in the advantageous section AT is the same as the expected value of the increase in the number of medals in the advantageous section AT when the control to the advantageous section AT is decided in the second period. The increase in the number of medals in section AT is smaller than the expected value (Y12<Y13, Y22<Y23). By doing so, it is possible to prevent the number of medals from increasing excessively even if it is easy to be controlled to the advantageous section AT in a relatively short period of time.

In addition, when control to the advantageous section AT is decided in the first period, the rate at which medals increase by a certain amount (the number reaching the limiter) in the advantageous section AT is the rate at which the number of medals increases by a certain amount (the number reaching the limiter) in the advantageous section AT in the second period. This is lower than the rate at which the number of medals equal to or greater than the specific amount increases in the advantageous section AT when control is determined (Z12<Z13). By doing so, it is possible to prevent the number of medals from increasing excessively even if it is easy to be controlled to the advantageous section AT in a relatively short period of time.

Furthermore, during the period from when the continuation control is performed until the specific number of games is played, the ratio of control to the advantageous section AT is lower than during the first period after the period (X11<X12). By doing so, it is possible to prevent medals from being paid out excessively in a short period of time.

In addition, when continuous control is performed, the expected value of the number of medals to increase in the next advantageous section AT when control is performed to the next advantageous section AT is the same as when control is performed to the next advantageous section AT when termination control is performed. is smaller than the expected value of the increase in the number of medals in the advantageous section AT when the number of medals increases (Y12<Y22). By doing so, it is possible to prevent the number of medals from increasing excessively even if it is easy to be controlled to the advantageous section AT in a relatively short period of time.

In addition, when continuous control is performed, the rate at which the number of medals increases by a specific amount (the number reaching the limiter) in the next advantageous section AT is determined by the end control. In this case, the rate is lower than the rate at which the number of medals equal to or more than a specific amount increases in the advantageous section AT when the next control is performed in the advantageous section AT (Z12<Z22). By doing so, it is possible to prevent the number of medals from increasing excessively even if it is easy to be controlled to the advantageous section AT in a relatively short period of time.

[Termination control and continuation control]
Hereinafter, with reference to FIG. 11, the control to the advantageous section AT and the transition of the net increase will be specifically explained when the end control and the continuation control are performed. FIG. 11 is a diagram for explaining termination control and continuation control. FIG. 11(a) shows an example of winning the advantageous section AT in a relatively short period of time in the normal advantageous section, and FIG. 11(b) shows an example of winning the advantageous section AT for a long period of time in the normal advantageous section. This is an example.

First, an example of winning the advantageous section AT in a relatively short period of time in the normal advantageous section will be explained. In this example, as will be described later, a transition pattern of the number of net increases is assumed in which setting 6 is set as the setting value. As shown in FIG. 11(a), it is assumed that the vehicle is currently controlled in an advantageous section AT. It is assumed that end control is performed when control to advantageous section AT ends. When the control to the advantageous section is completed by the end control, control is performed to the normal section (normal section normal).

It is assumed that the advantageous section is won in the 1st G after the normal section is controlled normally. In the next game in which the advantageous section is won, the game is controlled to be an advantageous section (advantageous section normal). As a result, the information regarding the advantageous section is initialized, and counting of the number of games played in the advantageous section is started.

In the example of FIG. 11A, assume that when the advantageous section is normally controlled, 220G is determined as the number of AT winning games, and 60G is determined as the number of AT games. In this case, the advantageous section AT is won in the 220th G after the normal section is controlled normally, and from the next game onwards, the advantageous section AT is controlled. Then, the vehicle is controlled to an advantageous section AT of 60G.

Then, when 60G elapses after being controlled to the advantageous section AT, the control to the advantageous section AT ends. At this time, it is assumed that continuous control is performed. By performing continuous control, the advantageous section continues without being controlled from the advantageous section to the normal section. Specifically, when the control for the advantageous section AT ends, the control for the advantageous section is normally controlled. In this case, information regarding advantageous sections is not initialized. Therefore, the main control unit 41 can grasp the net increase in the number of vehicles after being controlled to the advantageous section.

Next, it is assumed that when continuous control is performed and the advantageous section is normally controlled, 250G is determined as the number of AT winning games, and 60G is determined as the number of AT games. As a result, the advantageous section AT is won at the 220th G after the normal section is controlled normally, and from the next game onwards, the advantageous section AT is controlled to be 60G.

Then, when 60G elapses after being controlled to the advantageous section AT, the control to the advantageous section AT ends. At this time, it is assumed that continuous control is performed. It is assumed that when the advantageous section is normally controlled, 200G is determined as the number of AT winning games, and 80G is determined as the number of AT games.

It is assumed that termination control is performed when the 200G advantageous section normal and the 60G advantageous section AT end. As a result, control to the advantageous section (advantageous section AT) ends, and control to the normal section (normal section normal) is started. By performing the termination control, information regarding advantageous sections is initialized.

As shown in FIG. 11(a), the expected value of the number of medals that decreases while playing a specific number of games (200G) increases from when it is controlled to one advantageous section AT until the end of that advantageous section AT. smaller than the expected number of medals.

Next, an example will be described in which the player does not win the advantageous section AT for a long period of time in the normal advantageous section. In this example, as will be described later, a transition pattern of the number of net increases is assumed in which setting 1 is set as the setting value. As shown in FIG. 11(b), it is assumed that the vehicle is currently controlled in an advantageous section AT. It is assumed that end control is performed when control to advantageous section AT ends. When the control to the advantageous section is completed by the end control, control is performed to the normal section (normal section normal).

It is assumed that the advantageous section is won in the 1st G after the normal section is controlled normally. In the next game in which the advantageous section is won, the game is controlled to be an advantageous section (advantageous section normal). At this time, information regarding the advantageous section is initialized, and counting of the number of games played in the advantageous section is started.

Assume that when the advantageous section is normally controlled, 700G is determined as the number of AT winning games, and 200G is determined as the number of AT games. In this case, the advantageous section AT is won in the 700th G after the normal section is controlled normally, and from the next game onwards the advantageous section AT is controlled. Then, the vehicle is controlled to an advantageous section AT of 200G.

In the present embodiment, the main control unit 41 does not perform continuous control if the number of medals in the advantageous section AT has increased by a first amount or more when ending the control on the advantageous section AT. In this embodiment, the first amount is, for example, 1400 sheets. In this example, control is performed to an advantageous section AT of 200G. Since the 1G net increase is 8 sheets, the average net increase during the advantageous section AT is 1600 sheets (=8 sheets x 200G), which exceeds the first amount of 1400 sheets.

Note that the present invention is not limited to this, and if the number of medals has increased by the first amount or more during the controlled advantageous section when the control to the advantageous section AT ends, the continuous control may not be performed. . In addition, when the number of games played reaches a specific number (1500G), the limiter condition is met and control to the advantageous section ends, but continued control is executed depending on the number of games remaining until the limiter condition is met. It may also be possible to decide whether or not it is possible. For example, when the number of remaining games is less than or equal to a predetermined number of games, the continuation control may not be performed.

When 200G has elapsed after being controlled to the advantageous section AT, the control to the advantageous section AT ends. By executing the termination control, the control to the advantageous section (advantageous section AT) ends, and the control to the normal section (normal section normal) is performed. By performing the termination control, information regarding advantageous sections is initialized.

As explained above, in the example of FIG. 11(a), the winner wins in the advantageous section AT in a relatively short period of time in the normal advantageous section, whereas in the example of FIG. Do not win in the advantageous section AT. Comparing the example in FIG. 11(a) and the example in FIG. 11(b), in the example in FIG. 11(b), the number of staying games in the advantageous section normal is large, so the net increase in the number of games in the advantageous section AT is also large. On the other hand, in the example of FIG. 11(a), continuous control is repeated multiple times such that the number of staying games in the advantageous section normal is small and the number of games stayed in the advantageous section AT is also small. Also. By performing such continuous control multiple times, control is performed to stabilize the net increase.

[Relationship between continuous control, AT winning rate and net increase]
In the example shown in FIG. 10, when continuous control is performed, the AT winning rate, the number of AT acquired coins, and the rate of reaching 2400 coins are determined regardless of the ball output situation during the previous advantageous section AT. However, the present invention is not limited to this, and the following may be used.

When the control of the advantageous section AT ends, if the number of medals in the advantageous section AT has not increased by the second amount or more and the continuation control is performed, the number of specific games (200G ), if the number of medals has increased by the second amount or more in the advantageous section AT when the control for the advantageous section AT ends, and the continuous control is performed, The rate of control over the advantageous section AT may be set to be higher than during the period from when the game is played until the specific number of games is played. For example, the second amount is 500 sheets. In addition, in the above, it is not limited to "the number of medals increases by the second amount or more in the relevant advantageous section AT", but it also includes "the number of medals increases by the second amount or more during the controlled advantageous section". good.

In addition, if the number of medals has increased by the second amount (500 pieces) or more in the advantageous section AT when the control to the advantageous section AT ends, and the continuous control is performed, the control is performed on the next advantageous section AT. The expected value of the number of medals that will increase in the advantageous section AT when the control for the advantageous section AT ends is that the number of medals in the advantageous section AT has not increased by the second amount or more and that continuous control is not performed. In the case where this is done, the number of medals may be set to be smaller than the expected value of the increase in the number of medals in the advantageous section AT when the next control is performed in the advantageous section AT. In addition, in the above, it is not limited to "the number of medals increases by the second amount or more in the relevant advantageous section AT", but it also includes "the number of medals increases by the second amount or more during the controlled advantageous section". good.

In addition, if the number of medals in the advantageous section AT is increased by the second amount (500 pieces) or more when the control to the advantageous section AT ends, and the continuous control is performed, the control is performed on the next advantageous section AT. The rate at which the number of medals equal to or greater than a specific amount (the number reaching the limiter) increases in the advantageous section AT when the number of medals increases by a certain amount (the number of medals that reach the limiter) is determined by In the case where the number of medals has not increased and continuous control is performed, the rate may be lower than the rate at which the number of medals increases by a specific amount in the advantageous section AT when the next control is performed in the advantageous section AT. In addition, in the above, it is not limited to "the number of medals increases by the second amount or more in the relevant advantageous section AT", but it also includes "the number of medals increases by the second amount or more during the controlled advantageous section". good.

A specific example will be described with reference to FIG. 12. FIG. 12 is a diagram for explaining the relationship between continuous control, AT winning rate, and the number of net increases.

As shown in FIG. 12(a), it is assumed that when the control to the advantageous section AT ends, the termination control is performed and the normal control is performed in the normal section. Next, it is assumed that the advantageous section is controlled to be normal due to the advantageous section winning. It is assumed that 220G is determined as the number of AT winning games and 30G is determined as the number of AT games when controlling the advantageous section to normal. Assume that the number of medals increases by 240 due to the control to the advantageous section AT, that is, the number of medals does not increase by the second amount (500) or more, and continuous control is performed.

In this case, during the period until the specific number of games (200G) is played, compared to the example shown in FIG. The number of medals increases when the limiter is reached, and the rate at which the number of medals increases up to the limiter increases in advantageous sections. It is assumed that 180G is determined as the number of AT winning games and 350G is determined as the number of AT games when controlling the advantageous section to normal. By controlling to the advantageous section AT, the net increase in number becomes 2400 sheets and reaches the limiter.

Next, as shown in FIG. 12(b), it is assumed that when the control to the advantageous section AT ends, the end control is performed and the normal control is performed in the normal section. Next, it is assumed that the advantageous section is controlled to be normal due to the advantageous section winning. Assume that when controlling the advantageous section to normal, 220G is determined as the number of AT winning games, and 90G is determined as the number of AT games. Assume that the number of medals increases by 720 due to the control to the advantageous section AT, that is, the number of medals increases by a second amount (500) or more, and continuous control is performed.

In this case, during the period until the specific number of games (200G) is played, compared to the example in FIG. At times, the number of medals that increases becomes smaller, and furthermore, the rate at which the number of medals increases until the number reaches the limiter becomes lower in advantageous sections. It is assumed that 260G is determined as the number of AT winning games and 30G is determined as the number of AT games when controlling the advantageous section to normal. By controlling the advantageous section AT, the number of medals increases by 240. In this case, the limiter will not be reached by controlling the advantageous section AT.

[Freeze winning, regular winning and reset suggestion]
As described above, in the present embodiment, when the advantageous section AT is won (that is, when the control to the advantageous section AT is determined), the control is performed to the advantageous section AT from the next game. The decision to control the advantageous section AT is made, for example, when an operation to start an AT winning game is performed. The conditions under which control to the advantageous section AT is determined include a first condition and a second condition.

The first condition is, for example, a freeze win. The second condition is, for example, a normal AT win. A freeze win is a win that involves the execution of a freeze when the advantageous section AT is won. A normal win is a win that does not involve freezing when winning in the advantageous section AT. When a freeze win occurs, it is determined that the net increase in the number of tickets reaches 2400 in the advantageous section AT controlled by the freeze win. This will be explained in detail below.

The main control unit 41 can execute freezing when control to the advantageous section AT is determined (when the advantageous section AT is won). Freeze is a control performed by the main control unit 41, and is a delay control that delays the progress of the game. The main control unit 41 can freeze the game in which control to the advantageous section AT has been determined. Further, the sub-control unit 91 executes a freeze effect based on a command that is transmitted from the main control unit 41 and can specify freeze information. In this embodiment, when the start switch 7 is operated, the start of rotation of the reels is delayed for a predetermined period of time, and after the elapse of the predetermined period, the reels start rotating.

The main control unit 41 determines either a freeze win or a regular win when winning the advantageous section AT. The number of AT acquisition coins is determined by the AT acquisition number lottery, and if it is confirmed that the net increase will reach 2400 coins in the advantageous section, the freeze win is selected. On the other hand, the number of AT acquisition coins is determined by the AT acquisition number lottery, and if it is not determined that the net increase in number will reach 2400 coins in the advantageous section, the normal winning is selected.

When the freeze is won, after the start operation of the freeze winning game, the freeze is executed and a freeze effect is executed. The freeze effect is a effect that is executed in response to the freeze when the freeze is executed. The freeze effect is executed during the period in which the freeze is executed. Furthermore, the freeze performance is a performance that suggests control over the advantageous section AT and that the net addition number will reach 2400 sheets. In the freeze effect, an image of a treasure chest is displayed on the liquid crystal display 51. Then, a cloud appears from inside the treasure chest with the words ``extreme heat'' attached to it.

On the other hand, in the case of a normal winning, the normal effect is executed after the normal winning game start operation. The normal performance is a performance that suggests control to the advantageous section AT. In the normal performance, an image of a treasure box is displayed on the liquid crystal display 51. Then, a cloud with the word "chance" on it appears from inside the treasure chest.

FIG. 13 is a diagram for explaining freeze winning, normal winning, and reset suggestion effects. As shown in FIG. 13, after the end control ends the control to the advantageous section, the specific number of games (2
During the period (1G to 200G) until the 00G) is consumed, only the freeze win of the freeze win and the regular win can be achieved. If the number of AT winning games is determined to be in the range of 1G to 200G in the AT winning game number lottery, then the AT acquisition number lottery will be held so that the number of AT acquisition coins will be 2400.

In addition, in the period after the period until the specific number of games is played (specifically, from 201G to ceiling G), either the freeze winning condition or the normal winning condition can be satisfied. In this embodiment, a so-called "ceiling" is provided, and when the ceiling G is reached after the advantageous section is normally controlled, the advantageous section AT is always won at the ceiling G. For example, the ceiling G is 777G.

Further, the expected value of the increase in the number of medals in the advantageous section AT, which is controlled based on the establishment of a freeze win, is larger than the expected value of the increase in the number of medals, in the advantageous section AT, which is controlled based on the establishment of the normal AT win. For example, in this embodiment, if a freeze win occurs, it is certain that the net increase will reach 2400 in the advantageous section, while if a regular win occurs, the net increase will reach 2400 in the advantageous section. I'm trying not to reach that limit.

Further, as described above, in this embodiment, after the end control ends the control to the advantageous section, the rate of winning the advantageous section AT is lower in the period from 1G to 200G than in the first period. (Almost never wins). Furthermore, in the first period, the rate of winning AT in the advantageous section is higher than in the second period.

Further, in the present embodiment, the sub-control unit 91 can execute a reset suggestion effect. The reset suggestion performance is a performance that suggests that the control to the advantageous section will be performed again when the control to the advantageous section is to be performed again after the end control has ended the control to the advantageous section.

In this embodiment, the reset suggestion effect is executed when the end control ends the control to the advantageous section and a start operation is performed to start the control to the normal section. The reset suggestion effect may include, for example, displaying an image of a girl on the liquid crystal display 51 and displaying an image with the words "reset mode" attached thereto.

For example, the reset suggestion effect is executed from when a start operation is performed in a game that starts control to normal in the normal section until a predetermined condition (for example, the first stop operation or the third stop operation is performed) is satisfied. Alternatively, it may be always executed during normal section control. In addition, if a reset suggestion effect is always executed during control of the normal section to normal, it is possible to identify that the normal section is being controlled to normal so that it can be distinguished from other states such as advantageous section normal or advantageous section AT. A background image, an image with the words "reset mode" added thereto, or the like may be displayed.

[AT winning game number lottery]
As described above, using FIG. 10, the relationship between the number of played games, the AT winning rate (proportion of winning AT in the advantageous section), the number of AT acquired coins, and the rate of reaching 2400 coins was explained. Below, these relationships will be explained in more detail. First, the AT winning game number lottery will be explained using FIG. 14. Next, the AT acquisition number lottery will be explained using FIG. 15.

FIG. 14 is a diagram for explaining the AT winning game number lottery. The table in FIG. 14 is an AT winning game number lottery table used when performing an AT winning game number lottery. As described above, when the 1st G start operation which is normally controlled in the advantageous section is performed, the lottery for the number of AT winning games and the lottery for the number of AT acquisition coins are performed.

In this embodiment, the AT winning rate in each game differs depending on the setting value. Furthermore, the AT winning rate for each game differs depending on whether termination control is performed or continuation control is performed. Further, when continuous control is performed, the AT winning rate in each game differs depending on the number of medals (number of AT acquired) increased in the previous advantageous section AT.

Specifically, as shown in FIG. 14, the AT winning rate in each game is different depending on whether the setting is low or high. For example, a low setting is when the setting value is set to 1 to 3, and a high setting is when the setting value is set to 4 to 6. Note that the present invention is not limited to this, and the AT winning rate may be made different for each setting.

Furthermore, the AT winning rate for each game differs depending on whether termination control is performed or continuation control is performed. Further, when continuous control is performed, the AT winning rate in each game is different depending on whether pattern A is used or pattern B is used. Pattern A is a case where the previous AT acquisition number (net increase in the advantageous section AT) is less than the second amount (500 pieces), and pattern B is a case where the previous AT acquisition number is greater than or equal to the second amount (500 pieces). This is the case.

In the table of FIG. 14, after the control to the advantageous section ends, the period from when the control to the advantageous section is completed until the specific number of games (200G) is played is "1G to 50G", "51G to 100G", Corresponds to "101G to 150G" and "151G to 200G". The first period corresponds to "201G to 250G", and the second period corresponds to "251G to 300G".

For example, when setting 1 (low setting) is set as the setting value, the proportion of winnings in the advantageous section AT in the first period (201G to 250G) is ) is 23.0% (pattern A) or 21.0% (pattern B), and is 18.0% when termination control is performed (corresponding to X22 in FIG. 10). On the other hand, when setting 6 (high setting) is set as the setting value, the rate of winning in the advantageous section AT in the first period (201G to 250G) is lower than that when continuous control is performed (X12 in Fig. 10). ) is 50.0% (pattern A) or 47.0% (pattern B), and when termination control is performed, it is 45.0% (corresponding to X22 in FIG. 10). Thus, as shown in FIG. 10, the relationship X12>X22 holds.

Here, for example, the above-mentioned X12 (=23.0) indicates the rate of winning in the advantageous section AT in any of the 201st to 250th G in the first period. In other words, the number of AT winning games is determined to be one of 201G to 250G with a probability of 23.0%. It may be equally determined whether one of the 201G to 250G is determined. For example, one of the 201st G to 250th G is determined with a probability of 1/50. In this case, for example, the probability that the number of AT winning games is determined to be 201G is 23.0%×(1/50)=0.46%. That is, the AT winning rate in the 201st G is 0.46%.

In addition, when setting 1 (low setting) is set as the setting value, the proportion of winnings in the advantageous section AT in the second period (251G to 300G) is lower than that when continuous control is performed (corresponding to X13 in Fig. 10). ) is 6.0% (pattern A) or 5.0% (pattern B), and is 4.0% when termination control is performed (corresponding to X23 in FIG. 10). On the other hand, when setting 6 (high setting) is set as the setting value, the percentage of winning in the advantageous section AT in the second period (251G to 300G) is lower than when continuous control is performed (X13 in Figure 10). ) is 8.0% (pattern A) or 6.0% (pattern B), and when termination control is performed, it is 5.0% (corresponding to X23 in FIG. 10). Thus, as shown in FIG. 10, the relationship X13>X23 holds.

Furthermore, when setting 1 (low setting) is set as the setting value, the rate of winning the advantageous section AT in 1G to 200G is 1. 2% (0.3% + 0.3% + 0.5% + 0.1%) (pattern A) or 0.2% (pattern B) and when termination control is performed (corresponding to X12 in Figure 10) ) is 0.0%. On the other hand, when setting 6 (high setting) is set as the setting value, the probability of winning the advantageous section AT in 1G to 200G is 3 when continuous control is performed (corresponding to X13 in Fig. 10). .0% (pattern A) or 0.1% (pattern B), and when termination control is performed, it is 0.0% (corresponding to X23 in FIG. 10). Thus, as shown in FIG. 10, the relationship X13>X23 holds. Similarly, as explained using FIG. 10, the relationships of X11<X12, X13<X12, X21<X22, and X23<X22 also hold true.

Furthermore, when the setting is high such as setting 6, the AT winning rate in the first period (201G to 250G) is higher than when the setting is high such as setting 1. On the other hand, when the setting is high such as setting 1, the AT winning rate in 251G to 777G (period after the first period) is higher than when it is high setting such as setting 6. In particular, when the setting is high such as setting 1, the AT winning rate at 777G, which is the ceiling G, is higher than when the setting is high such as setting 6.

[AT acquisition number lottery]
FIG. 15 is a diagram for explaining the AT acquisition number lottery. The table in FIG. 15 is an AT acquisition number lottery table used when performing an AT acquisition number lottery. When the number of AT winning games is determined using the AT winning game number lottery table shown in FIG. 14, the number of AT winning tickets is determined using the AT winning number lottery table based on the determined number of AT winning games.

In the present embodiment, except for 0 to 200G (hereinafter also referred to as "first range"), the fewer the number of AT winning games, the smaller the number of AT winnings. For example, in the example shown in the table of FIG. 15, the number of AT winning games ranges from 400G to 777G (hereinafter also referred to as the "fourth range"), and the number of AT winning games ranges from 251G to 400G (hereinafter also referred to as the "third range"). If determined, the number of AT winning games is determined to be between 201G and 250G (hereinafter also referred to as the "second range"), and the number of AT won decreases in this order.

Since FIG. 15 shows the AT acquisition number lottery table when the end control is executed, the case where the end control is performed will be described below as an example. For example, the rate at which the number of AT winnings is determined to be 480 is 26.0% when the number of AT winning games is determined to be 220G (second range), whereas the percentage when the number of AT winning games is 700G (second range) is 26.0%. 4th range), it becomes 1.5%. Here, when the number of AT acquisition coins is determined to be 480 coins, the number of AT games awarded is 60G (=480 coins/1G net increase of 8 coins).

On the other hand, the rate at which the number of AT winnings is determined to be 1200 is 0.4% when the number of AT winning games is determined to be 220G (second range), but when the number of AT winning games is 700G. (4th range), it becomes 17.0%. Here, when the number of AT acquisition coins is determined to be 1200 coins, the number of AT games awarded is 150G (=1200 coins/1G net increase of 8 coins).

Additionally, the rate at which the number of AT winnings is determined to be 2,400 (the rate at which the limiter is reached) is 0.2% when the number of AT winning games is determined to be within the second range; If the number is determined to be in the fourth range, it will be 11.1%. Here, when the number of AT acquisition coins is determined to be 2400 coins, the number of AT games awarded is 300G (=2400 coins/1G net increase of 8 coins).

Further, the rate at which the number of AT winning coins is determined to be 2400 coins (the rate at which the limiter is reached) is 100% when the number of AT winning games is determined to be in the first range (1G to 200G). In other words, as explained using FIG. 13, when winning in 1G to 200G, the number of AT acquired coins is always determined to be 2400, a freeze win occurs, and a freeze and freeze effect are executed. It turns out.

As shown in Figure 15, when the number of AT winning games is determined to be in the second range, there is a high percentage of AT winnings of around 300 to 700 coins, whereas the number of AT winning games is in the fourth range. If it is determined, there is a high probability that the AT acquisition number will be about 900 to 1400 or 2400 (reaching the limiter). In the former case, the number of net additions will change as shown in FIG. 11(a), and in the latter case, the number of net additions will change as shown in FIG. 11(b).

Furthermore, as explained using FIG. 14, when the setting is high such as setting 6, the AT winning rate in the first period (201G to 250G) is higher than when the setting is high such as setting 1. At a high setting such as setting 1, the AT winning rate in 251G to 777G (period after the first period) is higher than when setting a high setting such as setting 6. Therefore, if the setting is high such as setting 6, the net increase will tend to change as shown in Figure 11(a), and if the setting is low such as setting 1, the net increase will tend to change as shown in Figure 11(b). The number of net increases is likely to change as follows. In this way, the pattern in which the number of net additions changes varies depending on the set value.

Also, for example, if the number of AT winning games is 1G to 200G, the percentage that the number of AT winnings is determined to be 2400 is 100%, and if the number of AT winning games is 201G to 250G, the number of AT winnings is 100%. If the number of AT won games is 251G to 300G, the percentage of AT winnings determined to be 300 to 399 coins is 28.0%. be. The average value of the number of AT winnings is, when the number of AT winning games is 201G to 250G (corresponding to Y22 in Figure 10), when the number of AT winning games is 251G to 300G (corresponding to Y23 in Figure 10), When the number of AT winning games is 1G to 200G (corresponding to Y21 in FIG. 10), the numbers increase in order. That is, as explained using FIG. 10, the relationships Y21>Y22 and Y23>Y22 hold true.

Also, for example, the rate at which the number of AT winnings is determined to be 2400 is 100% (corresponding to X21 in Figure 10) when the number of AT winning games is 1G to 200G, , it is 0.2% (corresponding to X22 in FIG. 10), and when the number of AT winning games is 251G to 300G, it is 7.0% (corresponding to X23 in FIG. 10). In other words, the rate at which the number of AT winnings is determined to be 2400 is when the number of AT winning games is between 201G and 250G, when the number of AT winning games is between 251G and 300G, and when the number of AT winning games is between 1G and 200G. The value increases in this order. That is, as explained using FIG. 10, the relationships Z21>Z22 and Z23>Z22 hold true.

Although the AT acquisition number lottery table when continuous control is executed is not shown in FIG. 15, in the table, as explained using FIG. 10, Y11<Y21, Z11<Z21, Y12< It is designed so that the relationships Y22, Z12<Z22, Y13<Y23, Z13<Z23, Y11>Y12, Z11>Z12, Y13>Y12, and Z13>Z12 hold true.

[Main effects]
Next, the main effects obtained by the embodiment described above will be explained.

(1) Equipped with a variable display section that can variably display multiple types of identification information, each of which can be identified,
In a slot machine (for example, slot machine 1) in which a display result is derived by variably displaying the variable display section, and then a display result is derived by stopping the variable display section, and winnings can be generated according to the display result,
a setting means (for example, a process of setting a setting value by the main control unit 41) capable of setting one of a plurality of levels of setting values having different degrees of advantage for the player;
Derivation operation means (for example, stop switches 8L, 8C, 8R) operated to derive display results;
A non-broadcasting section (for example, a normal section) in which operation information (for example, navigation information) corresponding to the operation mode (for example, pressing order) of the derivation operation means cannot be notified, and a notification section (for example, a normal section) in which the operation information can be notified ( for example, an advantageous section);
The section control means is
In the notification period, when the control to an advantageous state that is advantageous to the player (for example, advantageous period AT) ends, it is possible to perform end control to end the control to the notification period (for example, as shown in FIG. 3),
After the control to the notification period is terminated by the termination control, the period from when the notification period is controlled again until the specific number of games (for example, 200G) is played is longer than the period after the said period has passed. The ratio of being controlled to the advantageous state is low (for example, as shown in FIG. 10, X21<X22).

Specifically, as shown in FIG. 3, when the control to the advantageous section AT that is advantageous to the player is completed in the advantageous section, the main control unit 41 performs end control to terminate the control to the advantageous section AT. It is possible to do this. In addition, as shown in FIG. 10, after the end control ends the control to the advantageous section, the period from when the control is re-controlled to the advantageous section until the specific number of games (200G) is played is after the said period has passed. The rate of control in the advantageous section AT is lower than in the first period (201G to 250G) (X21<X22).

For slot machines, type tests are conducted for the purpose of regulating machines that are likely to significantly arouse the desire for gambling. In the type test, as a result of playing a specified number of games, if the ball payout rate, which is the ratio of the total number of medals paid out to the total number of medals used to set the number of bets, exceeds the upper limit, it is considered to be a sign of a significant gambling desire. Such slot machines are excluded as they are deemed to be potentially tempting. Therefore, if the control to the advantageous section AT, which is advantageous to the player, ends, and the control is again to the advantageous section AT after a short period of time, the above-mentioned ball payout rate will exceed the upper limit and , an excessive amount of medals will be paid out in a short period of time. This greatly arouses the desire for gambling. Under these circumstances, after the control to the advantageous section is finished by end control, the ratio of being controlled by the advantageous section AT during the period from when it is controlled again to the advantageous section until the specific number of games is played is reduced. In this way, it is possible to significantly reduce the desire for gambling, and it is also possible to prevent medals from being paid out excessively in a short period of time. In this way, it is possible to prevent the vehicle from being unintentionally continuously controlled to the advantageous section AT.

(2) The expected value of the amount of gaming value owned by the player (for example, the number of medals) that decreases while the specific number of games is played is from the time when the advantageous state is controlled until the end of the advantageous state. is smaller than the expected value of the amount of gaming value owned by the player that increases (for example, FIG. 11(a)).

Specifically, as shown in FIG. 11(a), the expected value of the number of medals that decreases during the playing of a specific number of games is as follows: The increase in the number of medals is smaller than the expected value. By doing so, the player does not need to add new medals and play the game until the specific number of games is played.

(3) The conditions under which the control to the advantageous state is determined include a first condition (for example, freeze winning) and a second condition (for example, normal AT winning),
Only the first condition of the first condition and the second condition can be satisfied during a period after the control to the notification period is finished by the end control and until the specific number of games is played. Yes (for example, Figure 13),
In the period after the period until the specific number of games is played, either of the first condition and the second condition can be satisfied (for example, FIG. 13).

Specifically, as shown in FIG. 13, the conditions under which control to the advantageous section AT is determined include freeze winning and normal AT winning. In addition, in the period after the control to the advantageous section is finished by the end control and until the specific number of games is played, only the freeze win of the freeze win and the normal AT win can be achieved. Further, in the period after the period until the specific number of games is played, either the freeze win or the normal AT win can be satisfied. By doing this, the player can expect a freeze win to occur.

(4) The expected value of the amount of gaming value owned by the player that increases in the advantageous state controlled based on the fulfillment of the first condition increases in the advantageous state controlled based on the fulfillment of the second condition. is larger than the expected value of the amount of gaming value owned by the player (for example, FIG. 13).

Specifically, as shown in FIG. 13, the expected value of the number of medals increases in the advantageous section AT, which is controlled based on the establishment of a freeze win, and increases in the advantageous section AT, which is controlled based on the establishment of a normal AT win. This is larger than the expected number of medals. By doing this, the player can expect a freeze win to occur.

(5) When at least one setting value (for example, setting 6) is set by the setting means, a specific timing when the specific number of games is played after the end control ends the control for the notification period. The rate at which the advantageous state is controlled in the first period (for example, 201G to 250G) from the timing when 200G is consumed is the same as the rate at which the advantageous state is controlled in the second period after the first period has elapsed from the specific timing (for example, , 251G to 300G) than the ratio of being controlled to the advantageous state (for example, as shown in FIG. 10, X22>X23).

Specifically, as shown in FIG. 10, when at least setting 6 is set, after the end control ends the control to the advantageous section, the first period starts from a specific timing (the timing when 200G is consumed). (201G to 250G), the ratio of being controlled to the advantageous section AT is higher than the ratio of being controlled to the advantageous section AT in the second period (251G to 300G) after the first period has elapsed from the specific timing (X22> X23). By doing this, players will be motivated to continue playing until they play a specific number of games, and it will be difficult for players to end the game as control to the advantageous section AT ends, so the operating rate of slot machines at game parlors will increase. can be improved.

(6) When control to the advantageous state is determined in the first period, the expected value of the amount of gaming value to increase in the advantageous state is equal to Sometimes, the amount of gaming value that increases in the advantageous state is smaller than the expected value (for example, as shown in FIG. 10, Y12<Y13, Y22<Y23).

Specifically, as shown in FIG. 10, when control to the advantageous section AT is determined in the first period, the expected value of the number of medals to increase in the advantageous section AT is the same as the expected value of the increase in the number of medals in the advantageous section AT in the second period. is smaller than the expected value of the increase in the number of medals in the advantageous section AT when control is determined (Y12<Y13, Y22<Y23). By doing so, it is possible to prevent the number of medals from increasing excessively even if it is easy to be controlled to the advantageous section AT in a relatively short period of time.

(7) When the control to the advantageous state is determined in the first period, the rate at which the gaming value increases by a certain amount (for example, the number of coins reaching the limiter) or more in the advantageous state is determined in the second period. It is lower than the rate at which the gaming value increases by the specified amount or more in the advantageous state when control to the advantageous state is determined (for example, as shown in FIG. 10, Z12<Z13).

Specifically, as shown in FIG. 10, when control to the advantageous section AT is determined in the first period, the rate at which the number of medals increases by a specific amount (the number reaching the limiter) in the advantageous section AT is , is lower than the rate at which medals increase by a specific amount or more in the advantageous section AT when control to the advantageous section AT is determined in the second period (Z12<Z13). By doing so, it is possible to prevent the number of medals from increasing excessively even if it is easy to be controlled to the advantageous section AT in a relatively short period of time.

(8) The section control means is capable of performing continuous control to continue control to the notification section when the control to the advantageous state ends in the notification section (for example, as shown in FIG. 3). ,
When at least one setting value (for example, setting 6) is set by the setting means, from the specific timing when the specific number of games is played after the continuous control is performed (for example, the timing when 200G is played) The rate at which the advantageous state is controlled in the first period (201G to 250G) is determined at a specific timing when the specific number of games has been played (for example, when 200G has been played) after the end control ends the control for the notification period. (for example, as shown in FIG. 10, X12>X22) is higher than the ratio of being controlled to the advantageous state in the first period (for example, 201G to 250G) from the timing when

Specifically, as shown in FIG. 3, when the control to the advantageous section AT ends in the advantageous section, the main control unit 41 can perform continuous control to continue the control to the advantageous section AT. It is. Further, as shown in FIG. 10, when at least setting 6 is set, the first period starts from a specific timing (timing when 200G is played) at which the specific number of games (200G) is played after continuous control is performed. (201G to 250G), the rate at which the advantageous section AT is controlled is determined from the specific timing (the timing at which 200G is played) at which the specific number of games (200G) is played after the control to the advantageous section is finished by the end control. This is higher than the ratio controlled by the advantageous section AT in one period (201G to 250G) (X12>X22). In this way, in the first period after the continuation control is performed, the ratio of control to the advantageous section AT is higher than in the first period after the end control is performed, so the control to the advantageous section is continued. The player can expect that continuous control will be performed.

(9) Setting means capable of setting any one of a plurality of levels of setting values with different degrees of advantage for the player (for example, a process of setting a setting value by the main control unit 41);
Derivation operation means (for example, stop switches 8L, 8C, 8R) operated to derive display results;
A non-broadcasting section (for example, a normal section) in which operation information (for example, navigation information) corresponding to the operation mode (for example, pressing order) of the derivation operation means cannot be notified, and a notification section (for example, a normal section) in which the operation information can be notified ( for example, an advantageous section);
The section control means is
In the notification period, when the control to an advantageous state that is advantageous to the player (for example, advantageous period AT) ends, it is possible to perform end control to end the control to the notification period (for example, as shown in FIG. 3),
In the notification period, when the control to the advantageous state is completed, it is possible to perform continuous control to continue the control to the notification period (for example, FIG. 3),
After the control to the notification period is terminated by the end control, the period from when the notification period is controlled again until the specific number of games (for example, 200G) is played is the period after the continuation control is performed. The ratio of being controlled to the advantageous state is lower than the period until the number of games is played (for example, as shown in FIG. 10, X21<X11).

Specifically, as shown in FIG. 3, when the control to the advantageous section AT that is advantageous to the player is completed in the advantageous section, the main control unit 41 performs end control to terminate the control to the advantageous section AT. It is possible to do this. Further, in the advantageous section, when the control to the advantageous section AT is finished, the main control section 41 can perform continuous control to continue the control to the advantageous section AT. Further, as shown in FIG. 10, after the end control ends the control to the advantageous section, the continuation control is performed during the period from when the control is again performed to the advantageous section until the specific number of games (for example, 200G) is played. The rate of being controlled by the advantageous section AT is lower than the period from when the player is defeated until the specific number of games is played (X21<X11).

For slot machines, type tests are conducted for the purpose of regulating machines that are likely to significantly arouse the desire for gambling. In the type test, as a result of playing a specified number of games, if the ball payout rate, which is the ratio of the total number of medals paid out to the total number of medals used to set the number of bets, exceeds the upper limit, it is considered to be a sign of a significant gambling desire. Such slot machines are excluded as they are deemed to be potentially tempting. Therefore, if the control to the advantageous section AT, which is advantageous to the player, ends, and the control is again to the advantageous section AT after a short period of time, the above-mentioned ball payout rate will exceed the upper limit and , an excessive amount of medals will be paid out in a short period of time. This greatly arouses the desire for gambling. Due to these circumstances, after the control to the advantageous section is finished due to end control, the period from when the control is re-controlled to the advantageous section until the specific number of games is played is the period after the continuation control is performed and the specific number of games is played. By lowering the ratio controlled by the advantageous section AT compared to the period until the end of the game, it is possible to significantly reduce the desire for gambling, and to prevent medals from being paid out excessively in a short period of time. I can do it. In this way, it is possible to prevent the vehicle from being unintentionally continuously controlled to the advantageous section AT.

(10) During the period from when the continuation control is performed until the specific number of games is played, the rate of being controlled to the advantageous state is lower than during the period after the period (for example, as shown in FIG. so that X11<X12).

Specifically, as shown in FIG. 10, during the period from when the continuous control is performed until the specific number of games is played, the rate at which the AT is controlled is more advantageous than in the first period after the period has elapsed. is low (X11<X12). By doing so, it is possible to prevent medals from being paid out excessively in a short period of time.

(11) In the case where the continuation control is performed, the expected value of the amount of gaming value that will increase in the advantageous state when the control is next performed in the advantageous state is When controlled to be advantageous, the amount of gaming value that increases in the advantageous state is smaller than the expected value (for example, as shown in FIG. 10, Y12<Y22).

Specifically, as shown in FIG. 10, when the continuation control is performed, the expected value of the number of medals to increase in the advantageous section AT when the control is next performed in the advantageous section AT is the same as the expected value of the number of medals that increases in the advantageous section AT. In this case, the expected value of the increase in the number of medals in the advantageous section AT when the next control is performed in the advantageous section AT is smaller than the expected value (Y12<Y22). By doing so, it is possible to prevent the number of medals from increasing excessively even if it is easy to be controlled to the advantageous section AT in a relatively short period of time.

(12) In the case where the continuation control is performed, the rate at which the gaming value increases by the specified amount or more in the advantageous state when the control is next performed in the advantageous state is the following in the case where the termination control is performed: is lower than the rate at which the gaming value increases by the specified amount or more in the advantageous state when the control is performed to the advantageous state (for example, as shown in FIG. 10, Z12<Z22).

Specifically, as shown in FIG. 10, when continuous control is performed, the next time control is performed to an advantageous section AT, the number of medals increases by a specific amount (the number of medals reaching the limiter) in the advantageous section AT. This rate is lower than the rate at which the number of medals increases by a specific amount in the advantageous area AT when the end control is performed and the next advantageous area AT is controlled (Z12<Z22). By doing so, it is possible to prevent the number of medals from increasing excessively even if it is easy to be controlled to the advantageous section AT in a relatively short period of time.

(13) When the notification period is controlled again after the control to the notification period is terminated by the end control, a suggestion effect that suggests that the notification period is controlled again (for example, a reset suggestion presentation) The apparatus further includes a suggestion effect execution means (for example, a process for executing a reset suggestion effect by the sub-control unit 91) (for example, FIG. 13).

Specifically, as shown in FIG. 13, when the control to the advantageous section is again performed after the control to the advantageous section is completed by the end control, the sub-control unit 91 controls the control to be controlled to the advantageous section again. Executes the suggested reset suggestion effect. In this way, by executing the reset suggestion effect when the termination control is performed, it becomes easy for the player to understand whether or not the continuation control is performed.

(14) If the gaming value has increased by a first amount (for example, 1400 coins) or more in the advantageous state when ending the control to the advantageous state, the section control means performs the continuation control. No (for example, FIG. 11(b)).

Specifically, as shown in FIG. 11(b), when the main control unit 41 ends the control for the advantageous section AT, the main control section 41 determines whether the number of medals increases by a first amount (1400 pieces) or more in the advantageous section AT. If so, do not perform continuous control. By doing this, it is possible to prevent the number of medals from increasing excessively, and it is possible to prevent the player's desire for gambling from becoming too intense.

(15) If the gaming value has not increased by a second amount (for example, 500 coins) or more in the advantageous state when the control to the advantageous state ends, and the continuation control is performed, the continuation During the period from when the control is performed until the specific number of games is played, when the control to the advantageous state ends, the gaming value has increased by the second amount or more in the advantageous state, and the continuous control When this is done, the ratio of being controlled to the advantageous state is higher than during the period from when the continuation control is performed until the specific number of games is played (for example, FIG. 12(a)).

Specifically, as shown in FIG. 12(a), when the control of the advantageous section AT ends, the number of medals has not increased by the second amount (500 pieces) or more in the advantageous section AT, and the continuous control is In this case, during the period from when the continuous control is performed until the specific number of games (200G) is played, when the control to the advantageous section AT ends, the second amount or more of medals will be awarded in the advantageous section AT. is increasing and continuous control is performed, the rate of control in the advantageous section AT is higher than in the period from when the continuous control is performed until the specific number of games is played. By doing this, even if the number of medals does not increase much, the player can expect control to move to the advantageous section AT again.

(16) If the gaming value has increased by the second amount or more in the advantageous state when the control to the advantageous state ends, and the continuous control is performed, then the control to the advantageous state is The expected value of the amount of gaming value that increases in the advantageous state when the control to the advantageous state ends is the case where the gaming value has not increased by the second amount or more in the advantageous state and the continuation of the When the control is performed, the amount of gaming value that increases in the advantageous state when the control is performed next time is smaller than the expected value (for example, FIG. 12(b)).

Specifically, as shown in FIG. 12(b), when the control for the advantageous section AT ends, the number of medals has increased by the second amount (500 pieces) or more in the advantageous section AT, and the continuous control is In this case, the expected value of the number of medals to increase in the advantageous section AT when the next control is applied to the advantageous section AT is the second amount in the advantageous section AT when the control to the advantageous section AT ends. In the case where the number of medals has not increased and continuous control is performed, the expected value of the number of medals to increase in the advantageous section AT when the next control is performed in the advantageous section AT is smaller than the expected value. By doing this, it is possible to prevent the number of medals from increasing excessively, and it is possible to prevent the player's desire for gambling from becoming too intense.

(17) If the gaming value has increased by the second amount or more in the advantageous state when the control to the advantageous state ends, and the continuation control is performed, then the control to the advantageous state is The rate at which the gaming value increases by the specified amount or more in the advantageous state when the control to the advantageous state ends is determined if the gaming value has not increased by the second amount or more in the advantageous state and In the case where the continuous control is performed, the rate at which the gaming value increases by the specified amount (the number of coins reaching the limiter) or more in the advantageous state when the control is next performed to the advantageous state is lower (for example, 12(b)).

Specifically, as shown in FIG. 12(b), when the control for the advantageous section AT ends, the number of medals has increased by the second amount or more (500 pieces) in the advantageous section AT, and the continuous control is In this case, the rate at which the number of medals in the advantageous section AT increases by a certain amount (the number of medals reaching the limiter) when the control is applied to the advantageous section AT is determined by the time when the control over the advantageous section AT ends. If the second amount or more of medals are not paid out in the advantageous section AT and continuous control is performed, the next time the control is performed in the advantageous section AT, the specified amount or more of medals will be paid out in the advantageous section AT. (for example, FIG. 12(b)). By doing this, it is possible to prevent the number of medals from increasing excessively, and it is possible to prevent the player's desire for gambling from becoming too intense.

[Modified example]
Although the main embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications and applications are possible. Modifications of the above embodiments applicable to the present invention will be described below.

[About the lighting state of the advantageous section LED 19]
In this embodiment, based on the control for the advantageous section, the advantageous section LED 19 is turned on to notify that the advantageous section control is being performed. The lighting timing of the advantageous section LED 19 is, for example, when the third stop is made in a game in which an advantageous section has been won, or when a start operation is performed to start a game that starts control to the advantageous section. However, the present invention is not limited to this, and the timing at which the advantageous section LED 19 is turned on may be set as follows.

For example, the advantageous section LED 19 may be turned on after the third stop in the 2nd G (or in subsequent games) when control to the advantageous section ends due to end control and control to the normal section starts. You can also do this. Further, by lighting the advantageous section LED 19, it is possible to suggest a transition to an advantageous section, and to execute an advantageous section transition suggestion effect in which an image suggesting a transition to an advantageous section is displayed on the liquid crystal display 51. . Further, when the player wins the advantageous section in the normal section, an image indicating that the player wins the advantageous section may be displayed in the game. Further, the advantageous section shift suggestion effect may be executed at the timing when the start operation is performed in the 2nd G (or in subsequent games).

In this embodiment, the probability of winning the advantageous section is very high in the first game in which control to the normal section is started. However, in the first game, rather than turning on the advantageous section LED 19 or performing an advantageous section shift suggestion effect at the timing of the third stop, in the second game or later, turning on the advantageous section LED 19 or executing an advantageous section shift suggestion effect. By executing , it becomes easier to distinguish whether termination control or continuation control has been performed.

[About advantageous sections]
In the present embodiment, the states in the advantageous section include the normal section normal and the advantageous section AT, but may also include CZ. CZ is a state in which navigation can be executed. AT is a state in which navigation can be executed, and the probability of navigation execution is higher than in CZ. The net increase in the number of games per game that the player can acquire during AT is larger than the net increase in the number of games per game that the player can acquire during CZ. Normally, when a player wins in the CZ lottery, the state is controlled to be CZ. Control over the CZ is managed by the number of games, and the CZ ends on the condition that the number of games played during the CZ reaches a predetermined upper limit number of games. Furthermore, based on the AT winning in CZ, the state is controlled from CZ to AT. When controlled from CZ to AT, the control is again changed to CZ after AT ends. If AT wins in CZ, it will be controlled by AT again. On the other hand, if the number of games played reaches the upper limit number of games without winning an AT in CZ, the state is controlled in normal mode. When applied to this embodiment, for example, when a lottery for the number of AT winning games is performed, a lottery may be performed to determine whether to shift to CZ at the same time. If the CZ is won, the control may be made to the CZ at the number of games obtained by subtracting the number of CZ execution games from the number of AT winning games.

Note that the various configurations, various processes, timings of various processes, etc. in the present embodiment and the modified examples described above can be combined as appropriate.

The embodiments disclosed this time should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is indicated by the claims rather than the above description, and it is intended that all changes within the meaning and range equivalent to the claims are included.
