Description

This application claims priority for Japanese Patent Application No. 2004-040648, filed February 17, 2004, the contents of which are incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates to gaming machines, such as a pachislo gaming machine, a gaming machine with rotating reels, and the like.

State of the art

Description will be given using an example of a gaming machine with rotating reels, specifically a gaming machine of the type pachislo. This type of gaming machine contains three reels arranged in the same line adjacent to each other, which visually display many types of symbols on their external surfaces. If coins were inserted, then when the start switch is turned on, the reels begin to spin and the symbols on the outer surface of each reel are displayed alternately. In this state, if the stop switches for each drum are actuated, the respective drums are stopped.

When all the reels are stopped by such an action, if the symbols that have stopped on the pay line determined by the number of coins entered satisfy a predetermined winning combination, then the player is awarded. The prize awarded to a player is a prize in the form of coins paid to him as a prize depending on the winning combination, or the prize is a large bonus (hereinafter referred to as BB) or an ordinary bonus (hereinafter referred to as OB), which makes it possible to participate in a special game in which coins can be won in larger quantities than in a regular game.

Therefore, the player operates the stop switch so that the combination of symbols satisfies the winning combination. When the player operates the stop switch skillfully, the player can receive wins and can enjoy the games. Operating the stop switch so that the combination of characters satisfies the winning combination is usually called a stop for visual inspection, or control stop. However, when the reels spin, the symbols are alternately displayed at high speeds, so that not all players are capable of performing a control stop operation. In other words, a control stop operation is an operation that can only be performed by a subset of players having excellent visual ability to perceive mutable objects and having gained great game practice.

Meanwhile, the popularity of slot machines has increased in recent times. However, younger players who are forbidden by law to play this type of slot machine more often also want to play, and the difference in the gain has developed, achieved not just by luck, but by the technical techniques that the player possesses. Therefore, the number of players who wish to practice playing a game on a slot machine is increasing, and the number of slot machines, which are the same as those in Japanese pachinko halls, are now placed in the arcade game galleries.

The aforementioned players use the number of slot machines that are placed in the arcade galleries to hone their techniques. However, since a test stop is difficult for beginners, in order to get used to it, they must go through repeated failures in order to learn the techniques of a control stop. Thus, on a regular slot machine, the assimilation of the technical techniques of a control stop was counted, it takes a lot of time, perseverance and money to play by the rules (games), and there is a difficulty that repelled many players.

Therefore, traditionally, in order to allow a person who does not have a game practice to easily perform a control stop operation, gaming machines have been proposed in which the rotation speed of the drum decreases when a predetermined condition is satisfied.

In one gaming machine of this type, a proposal was made for a gaming machine in which the BB, OB and other win flags are internally set, and when a predetermined number of continuous failures occurred in which the player was unable to stop the corresponding symbols, the rotation speed of the rotating reels changes from high speed (normal rotation speed) to low rotation speed (see the publication of Japanese patent pending Nos. N5-003943, 2001-062039, 2002-233610, 2003-062169 and 2003-210666).

However, these gaming machines are not designed so that the rotation speed of the reel can be changed by actions performed by the player. Changes are implemented by controls that are internal to the gaming machine.

In the method in which the internal control slows down the rotation speed of the rotating reels with the win flag set internally, there are cases in which the gain to the player is too great. This destroys the balance of wins between the Japanese pachinko hall and the player, thus creating a new problem for the Japanese pachinko halls because of the disadvantage.

Additionally, instead of the Japanese pachinko hall, in which the gaming machine, included in the gallery of gaming machines, is installed containing this type of automatic speed reduction function, the rotation of the rotating drum is different from that for the actual game

- 1 008395 of the total number of automatic machines. This makes it difficult for a trained player to put it into practice.

In addition, in a method in which the rotation speed of the rotary drum is reduced in the case where the win flag is set internally, the win flag thus becomes announced to the player. Thus, it is too easy for a trained player to find out what the result will be. This makes it difficult to reduce the pleasure of guessing whether the flag has been internally set.

In one gaming machine, to solve these types of difficulties, a gaming machine was considered that has a rotation speed change switch so that the player can act independently to reduce the rotation speed of the reels. In a gaming machine containing the aforementioned rotation speed change switches, the player can select the rotation speed of the reels in accordance with the player's level of practice. This creates an attractive slot machine. However, depending on the player, it can be imagined that the player always activates a rotation speed change switch, whereby the significance of techniques is greatly reduced. This will invalidate the original attractiveness of the slot machine.

SUMMARY OF THE INVENTION

The present invention has been made to solve the above problems. The objective of this invention is to provide a gaming machine that allows the player to select the rotation speed of the reels in accordance with the level of practice of the player, and also allows the player to operate the change of rotation speed switch only when, for example, an effect (result) shows that it is highly likely that a particular flag is set, thus increasing or adding to the attractiveness typical of slot machines.

The payout amount display unit 18 consists of a seven-segment LED and displays the number of coins that will be paid out when a win is set. The game coin introduction indicator 24 is displayed when game coins can be received.

In the upper right corner of block 2a of the display panel, a block 20 for displaying the number of additional games is provided. Block 20 displaying the number of additional games consists of a seven-segment LED and displays the number of possible OB games, the number of possible winnings of OB games, etc., which are described below. Below the display windows 4b, 4C and 4B, a main part 10 is provided consisting of a horizontal surface. Between the main part 10 and the display windows 4b, 4C and 4B, a liquid crystal display (display) device 5 is provided. Images of various effects (results) are displayed on the indicator screen 5a of the liquid crystal display device 5.

In the upper left location on the display panel unit 2a, a game stop indicator 31, a restart indicator 32, an OB operation indicator 33, and a BB operation indicator 34 are provided. The game stop indicator 31 is displayed while waiting for a predetermined period of time (for example, 4.1 s) to elapse from the rotation of the previous main reel to the rotation of the current main reels. The restart indicator 32 lights up when a restart is occurring. Indicator 33 of the operation OB illuminate when there is OB. The BB operation indicator 34 lights up when a BB occurs.

A slot 22 for lowering coins is provided on the right side of the liquid crystal display device 5.

On the left on the front of the surface of the main part 10 there is a switch 14 for calculating the stored coins, which is pressed to switch between the provision of credit / payment of coins that the player won during the game. When this switch 14 calculation of the stored coins is switched, the coins are paid out from the hole 15 of the payment of coins located on the front lower part. The paid coins are accumulated in the coin acceptor 16. On the right side of the stored coin calculation switch there is a start lever 6, which can rotate freely within a predetermined angular movement and which the player sets in motion to make the main reels rotate and trigger a variable display of characters in windows 4b , 4C and 4B display (i.e. start the game).

In addition, to the right of the main part 10, a switch 101 for changing the rotation speed is provided. When this rotational speed change switch 101 is actuated as described above, and a predetermined condition is satisfied, the rotational speed of the main drum can be changed, for example, from 80 to 70 rotations / min.

- 4 008395

According to the present embodiment, by acting on the rotation speed change switch 101, the speed is changed to a predetermined rotation speed that is lower than normal (lower low rotation speed in the document). However, the rotation speed change switch 101 is, for example, a 3-level switch, and in addition to switching to a low speed, it can also set a higher speed than usual, for example 90 rotations / min, to be included in the practice of a test stop.

In addition, the rotation speed change switch 101 can also be created using an analog switch, so that the rotation speed of the main drum can be set freely within a predetermined range (for example, from 60 to 80 rotations / min). By adopting a method of accelerating the rotation speed of the main drum gradually, for example, one can be included in practice in accordance with the skill level. This type of change in the function of the rotation speed change switch can also be applied to the gaming machine according to the present invention corresponding to the second embodiment, which is described below. The above explanation has illustrated specific rotational speeds, but in the present invention, the variable rotational speeds of the drum are not limited to the above values.

On the right on the front surface of the main part 10 is a device 29 for opening / closing the door and stop-reset. Using a pre-set key, the door open / close and stop / reset device 29 is turned right to open / close the front door and turned left to reset (cancel) the stop.

At the top left and right on the housing 2 there are speakers 21b, 21B. Between these speakers 21b, 21B, a payout table panel 23 is provided that displays combinations of winning symbols, payout amount, etc. Three stop switches 7b, 7C, 7B are provided in the center of the front surface portion of the main part 10, below the liquid crystal display device 5, so that stop each of the main drums 3b, 3C, 3B.

Each of the main reels 3b, 3C, 3B has 21 characters from a plurality of character types that line up to form columns of characters. Each character has a code number from 00 to 20, which is stored as a data table in a read-only memory (ROM, VOM) 32, which is explained below. Each of the main reels 3b, 3C, 3B displays a column of characters made up of characters such as blue 7, red 7, strip, bell, drain, restart, and cherry, for example. Each of the main reels 3b, 3C, 3B is rotated so that the character column moves in a predetermined direction.

ROM 42 stores a plurality of types of probability lottery tables used to determine symbols of an internal winning combination. The table of the probabilistic lottery of internal winnings varies depending on the state of the game, but each time it is a table that establishes the correspondence between the range of predefined random numbers selected from the range from 0 to 16383 and the symbol of the combination that fell out. When determining the symbol of the internal winning combination, a certain numerical value (random number) that is extracted by the internal lottery is used to determine the symbol of the internal winning combination. In the aforementioned table of the probabilistic lottery of internal wins, the probability of internal winnings in the state of a regular game can be set to 55/16384 for BB, 28/16384 for OB, 2245/16384 for restart, 63/16384 for cherries and so on.

When, for example, blue 7-blue 7-blue 7 or red 7-red 7-red 7 are located along the activated line, the BB is won, so that fifteen coins are paid and the game state of the BB becomes the game state for the next game.

The game state OB occurs in the state of a normal game in the case when the combination of symbols located in the activated line is, for example, a strip-strip-strip, or in the state of a normal game within the BB in the case when the combination of symbols located (in a line) along the activated line, is, for example, Restart-Restart Restart (the so-called 1LS ΙΝ), and thus fifteen coins are paid. Sometimes they distinguish: OB, which begins in the state of an ordinary game, is called ordinary OB, and OB, which begins from the state of a regular game in the framework of BB, is called OB in the framework of BB.

A game state OB is a game state in which a player can bet one coin, and if a predetermined combination of symbols is generated, such as, for example, Re-start-Restart-Re-start, the combination for winning fifteen coins can be easily won. In the single case of the OB game state, the maximum number of games that can be played (this is called the possible number of OB games) is, for example, twelve. The number of wins that can occur (this is called the possible number of OB wins) is, for example, eight. In other words, the state of the OB game ends, for example, after twelve games or after eight wins. Then, when the state of the game OB ends, the state of the game is changed to the state of the normal game.

A single BB ends when thirty games were played in a regular game within the BB, or when the game state is changed to the game state AB three times, it ends

- 5 008395 is on the third OB. Then, in the case when the state of the game BB ends, the state of the game is changed to the state of a normal game.

In a normal game state, a restart is advantageous when the combination of characters along the activated line is Restart-Restart-Restart. When the re-launch wins, the same amount of coins that is entered becomes automatically entered so that the player can play without spending coins.

Sub drum 38 has a plurality of character types aligned to form a column of characters. Each symbol has a code number, and they are stored in ROM 85, related to the control subcircuit 82, which is explained below. The characters located on the sub drum 38 are not specifically limited. They can be sets of different scenes of specific moving images (animations), signs (c) of various combinations, drawings or the like, or images of famous pop artists, actors, athletes or the like in action. The sub drum 38 is rotatable / actuated so that the character column moves in a predetermined direction. However, the movement is not limited in any direction and can sometimes rotate in the opposite direction.

Typically, a symbol that stops / is displayed on the sub drum 38 indicates that OB, BB, a symbol of a small combination or other specific symbol of a dropped combination coincides internally (contains an internal match), or to indicate that a particular symbol of a dropped combination has a high probability of occurring internally, or to suggest combinations of characters that may be dropped out internally, or to indicate other different types of game state.

In FIG. 3 is a block diagram of a circuit structure and the like that includes a main control circuit 81 for controlling game processing operations in the gaming machine 1, a peripheral device (actuator) that is electrically connected to the main control circuit 81, and a control subcircuit 82 for in order to control the liquid crystal display device 5 and the speakers (speakers) 21B, 21B based on control commands sent from the main control circuit 81.

The main structural element of the main control circuit 81 is a microcomputer 40 located on a circuit board. Added to this is a random number sampling scheme. The microcomputer 40 includes a central processing unit (CPU, SRI) 41 for performing control operations in accordance with a pre-configured program, and a read-only memory 42 and a random access memory (RAM, BAM) 43, which are storage means.

Connected to the CPU 41 are a clock pulse generating circuit 44, and a frequency divider unit 45 for generating a standard pulse, and a random number generator 46 and a sampling circuit 47 for generating random numbers to be selected. It should be noted that, as a means for sampling random numbers, random sampling can be performed inside the microcomputer 40, that is, in the running program of the CPU 41. In this case, the random number generator 46 and the sampling circuit 47 may be absent or may be left for maintenance as backup for random numbers fetch operation.

The ROM 42 of the microcomputer 40 stores probabilistic lottery tables used to determine a random number sample executed after each action of the start lever 6 (each start operation), a stop control table for determining a stop state of the main reels in response to the actuation of the stop switches, various control commands (commands) for sending to the subcircuit 82 controls, etc. It should be noted that information exchanges are performed unidirectionally from the main control circuit 81 to the control subcircuit 82, without inputting commands, information or the like, from the control subcircuit 82 to the main control circuit 81.

In the circuit of FIG. The 3 main actuators, the actions of which are controlled by control signals from the microcomputer 40, are various indicators (bet indicator 9a-1, bet indicator 9b-2, maximum bet indicator 9c, win indicator 17), various display units (payout amount display unit 18 , a unit 19 for displaying the stored number of coins and a unit 20 for displaying the number of additional games), a coin collector (including a drive unit for making payments) 50, which is used as a means of pricing the games s, to save coins and pay a predetermined number of coins in accordance with the command from the coin collector drive (control) circuit 51, and step motors 59B, 59C, 59B for controlling the rotation of the main reels 3b, 3C, 3B.

In addition, the electric motor driving circuit 49 for driving / controlling the stepper motors 59B, 59C, 59B, the coin collector drive circuit 51 for driving / controlling the coin collector 50, the indicator driving (control) circuit 55 of indicators for driving / controlling various indicators and indicator control circuit 58 for driving / controlling various display units are connected via input / output port 48 (Ι / Ο) to the output unit of CPU 41. Each of these control circuits receives commands actuation and other control signals that are issued from the CPU 41 and control the operations / actions of each activation unit.

- 6 008395

In addition, as the main means of generating the input signals, which generates the necessary input signals for the microcomputer 40 in order to generate control commands, there are a start switch 68, a bet-1 switch 11, a bet-2 switch 12, a maximum bet switch 13, a switch 14, calculation of stored coins, rotation speed change switch 101, inserted coin sensor 228, drum stop signal circuit 56, drum position determination circuit 60 and payout completion signal circuit 61. They are also connected to the CPU 41 via an input / output port 48.

The start switch 68 detects the action of the start lever 6. The inserted coin sensor 228 detects coins inserted in the coin lowering member 22. The drum stop signal circuit 56 generates a stop signal in response to the action of each of the stop switches 7b, 7C, 7B. The drum position determination circuit 60 receives a pulse signal from the drum rotation sensor and provides a signal to the CPU 41 to determine the position of each of the main drums 3b, 3C, 3B. The payout completion signal circuit 61 generates a signal for detecting the completion of the payout of coins in the case where the calculated value from the coin determination unit 508 (the number of coins paid from the coin collector 50) takes a data value of the indicated number of coins.

In the circuit of FIG. 3 shows that a random number generator 46 generates a random number within a predetermined range of values. Sampling circuit 47 selects one random number at a corresponding point in time after the action of trigger 6. The symbol of the internal winning combination is determined based on a random number that is generated in this manner and the probability lottery table stored in the ROM 42. After the symbol of the internal winning combination is determined, a random number is again sampled to determine a stop control table.

After the rotation of the main drums 3B, 3C, 3B is started, the number of exciting pulses that were applied to each of the stepper motors 59B, 59C, 59B is calculated. The value of the total amount is recorded in a predetermined area of RAM 43. The resulting pulse is obtained from the main drums 3b, 3C, 3V after each rotation and these pulses are input to the CPU 41 by means of a drum position determination circuit 60. The resulting pulses thus obtained reset to 0 the values of the total sum of the exciting pulses, which are summed in RAM 43. Accordingly, for each of the main drums 3b, 3C, 3V RAM 43 stores the value of the total sum, which corresponds to the rotation position within one revolution .

The symbol table is stored inside the ROM 42 to establish correspondence between the aforementioned rotation positions of the main drums 3b, 3C, 3B and the symbols located on the outer surfaces of the main drums. In this symbol table, the rotation position at which the aforementioned reset pulses are generated serves as a reference point, and correspondence is established between the code numbers that are sequentially assigned to the specified intervals of rotation steps for each main drum 3b, 3C, 3B, and symbol codes denoting symbols corresponding to each of the code numbers.

According to the gaming machine according to the present invention, an area for storing information whether to change to slow rotation (flag for changing rotation speed) is determined within a predetermined area of RAM 43. When the rotational speed change switch 101 is actuated, this rotational speed change flag is set. When the rotation of the drum is close to starting, for example, the CPU 41 reads the rotation speed change flag, and when the flag is set, the intervals between the excitation pulses that are supplied to each of the stepper motors 59b, 59C, 59B are changed to change the speed of rotation of the drums to slow rotation. However, in the present invention, if another condition is not satisfied, then the flag for changing the rotation speed will be cleared, the change in the rotation speed of the drums will not be implemented.

It should be noted that the checkbox for changing the rotation speed is automatically cleared when one game ends. In the next game, the main reels will rotate at normal rotation speed if they do not operate the rotation change switch 101.

In addition, inside the ROM 42, a table of winning symbol combinations is stored. The table of winning symbol combinations establishes the correspondence between the symbol combinations that form the winnings, the number of coins to be paid out for winning and the win determination codes that indicate the winnings. The aforementioned symbol winning combination table is accessed when a stop control is performed on the left main reel 3b, the middle main reel 3C and the right main reel 3B, and when confirming the win after the reels have been stopped.

When the lottery processing (probabilistic lottery processing), which is performed based on the aforementioned random number sample, generates an internal gain, the CPU 41 sends a signal to the motor control circuit 49 to stop / control the main reels 3b, 3C, 3B based on the operation signal sent from the drum stop signal circuit 56 in the case where the player operates the stop switches 7b, 7C, 7B, and based on the selected table

- 7 008395 stop control.

When the stop combination indicates a win for the combination symbol that has fallen internally, the CPU 41 then delivers the payout command signal to the collector drive circuit 51 and pays out a predetermined amount of coins from the collector 50. At this point, the coin determination unit 508 calculates the number of coins that will be paid out of coin collector 50. When the total amount reaches the designated amount, a signal to complete the payment of coins is input to the CPU 41. Accordingly, the CPU 41 stops the operation of the coin collector 50 by the coin collector drive circuit 51, and thus, the coin payout processing is completed.

In FIG. 4 shows a block diagram of the structure of a control subcircuit 82. The control subcircuit 82 performs functions such as display control for the liquid crystal display device 5 and control of the sound output from the speakers 21b, 21B based on control commands from the main control circuit 81. The control subcircuit 82 is created on a circuit board that is not the circuit board on which the main control circuit 81 is built. The main structural element is a microcomputer (hereinafter referred to as a submicrocomputer) 83. A control subcircuit 82 is constituted together with an image control circuit 91 used as a display control for the liquid crystal display device 5, an audio source integrated circuit (IC, 1C) 88 for controlling the sound output from the speakers 21b, 21B, and a power amplifier 89 used as an amplifier.

The submicrocomputer 83 includes a sub-CPU 84 for executing control actions / operations in accordance with control commands sent from the main control circuit 81, program ROM 85 used as a storage medium, and a working RAM 86. The control subcircuit 82 does not contain a generating circuit a synchronizing pulse, a frequency divider, a random number generator or a sampling circuit, but is designed to perform random number sampling in sub-CPU 84 programs.

The software ROM 85 stores a control program that is to be executed on the sub-CPU 84. The working RAM 86 functions as a temporary storage facility when the aforementioned control program is executed on the CPU 84. In addition, the program ROM 85 also stores a program for operating sub-drum 38. It should be noted that the sub-drum 38 starts to rotate simultaneously with the main reels when the start switch 68 is used.

An electric motor control circuit 110 for driving / controlling a stepper motor 598 that rotates / controls the sub drum 38, a motor control circuit 110 that drives / controls the stepper motors 598. is connected to the sub-CPU 84 through an input / output port. in addition, a drum position determination circuit 111 for generating an input signal is also connected.

The ROM 85 stores a database in which code numbers are assigned to each of the symbols on the sub drum 38. The position of the drum is determined in the same manner as for the main drum. The sub drum 38 displays a predetermined effect (symbol) after a predetermined length of time has elapsed since the start switch 68 has been activated. The sub-CPU 84, after the drum position has been determined in the aforementioned manner according to the symbol, executes a stop request to stop at the desired symbol in accordance with that symbol. For the drum 38 there is no limitation on the number of frames to change or the like, so that it can move until it stops at the desired character.

It should be noted that in accordance with the present embodiment, a particular effect is shown when a particular symbol of the combination that has fallen matches internally. The ROM 42 of the main control circuit 81 stores a sub drum effect table in which a plurality of symbol combinations are recorded on the main drum and symbol combinations that are stopped on the sub drum 38. The CPU 41 outputs a signal to the control subcircuit 82 based on the sub drum effects table. The CPU 84 of the control subcircuit 82 stops the sub-drum 38 at the desired symbol if a predetermined time elapses after the start switch 68 has expired.

In addition, when the rotation speed change switch 101 is actuated, a table for determining whether the change in the rotation speed of the main drum is in effect or not, namely, a specific effect table in which the effects (symbols) of the sub drum 38 and specific symbols of the internal winning combination are recorded and similar, save in ROM 42 of the main control circuit 81. Based on a specific table of effects, it is determined whether the effect (symbol) that is stopped / displayed on the sub drum 38 is an effect (symbol) that makes it possible to actuate the rotation speed change switch of the main drums.

An image management circuit 91 is formed together with an image management CPU 92, a working image management RAM 93, an image management program ROM 94, an image ROM 96, a video RAM 97 and an image management integrated circuit 98. The image control CPU 92, based on the parameters set by the sub-microcomputer 83, determines the image content for the liquid crystal display device 5 in accordance with the control program

- 8 008395 image stored inside the ROM 94 of the image management program. The ROM 94 of the image management program stores an image management program and various sampling tables corresponding to a display on the liquid crystal display device 5. The working image management RAM 93 is created as a temporary storage means in the case where the aforementioned image management program is executed on the image management CPU 92.

The image management integrated circuit 98 forms an image in response to the display contents determined by the image management CPU 92 and outputs it to the liquid crystal display device 5. The image ROM 96 stores data about the points that make up the image. Video RAM 97 is created as a means of temporary storage in the case when the image forms the integrated circuit 98 of the image management.

In FIG. 5-6 are flowcharts of routines that are executed on the gaming machine shown in FIG. 1-2. Subprograms are called and executed with a predefined time reference from the main program, which is already executable. The explanation of the game execution processing programs is given with a separate explanation shown in FIG. 5 of the game execution processing program 1 and shown in FIG. 6 programs 2 processing the execution of the game.

First, as shown in the game execution processing program 1 of FIG. 5, the CPU 41 determines whether there is a request for the automatic insertion of coins (block 810). It should be noted that in the case when there is a request for automatic introduction, in the previous game the restart should be won. When there is a request for the automatic insertion of coins, the requested number of coins is automatically entered (step 811), and the coin injection command is sent to the control subcircuit 82 (step 812).

On the other hand, at step 810, when it is determined that there is no request for the automatic insertion of coins, the CPU 41 determines whether the coins have actually been entered (step 813). In other words, the CPU 41 determines whether a detection signal issued by the coin input sensor 228 is valid, which determines that the coins inputted to the coin lowering member 22 are received, thereby determining whether coins are inserted.

At step 813, in the case when it is determined that no coins have been entered, the CPU 41 returns the processing to step 810. At step 813, in the case when it is determined that the coins have been entered, or in the case where the processing corresponding to step 812 is executed, then determination is made whether the trigger 6 is actuated (block 814). In other words, the CPU 41 determines whether an input signal is received from the start switch 68.

In step 814, in the case where it is determined that the start lever 6 is not actuated, the CPU 41 then returns to step 814. On the other hand, in the case where it is determined in step 814 that the start lever 6 is activated, the CPU 41 then performs various settings (block 815).

In processing various settings, when the trigger 6 is actuated, the random number generator 146 selects random numbers. Based on the value of the random number that is selected and based on the probability lottery tables set in RAM 43, lottery processing is performed to form an internal winning combination symbol (win flag). In addition, when processing for setting various tuning parameters, for example, processing the winning indicator highlighting lottery, processing is performed for selecting a stop control table to stop the spinning reels, processing for sending the start command to the control subcircuit 82 as a send processing at the start of the game, and processing to initialize the start of rotation of the drum, etc., which starts the rotation of the main reels 3 (3b, 3C, 3K). At this point in time, the CPU 41 sends a control signal to the control subcircuit 82 and causes the sub-drum 38 to rotate simultaneously with the main drums 3 (3b, 3C, 3K).

After that, the CPU 41 determines whether a predetermined time has elapsed (whether it is time to stop the sub-drum) (step 816). If the predetermined time duration has not elapsed, the processing returns to step 816. The predetermined time duration in step 817 is preferably from about 1 to 5 seconds.

When the CPU 41 determines that the predetermined length of time has expired, a sub-drum effect table stored in the aforementioned ROM 42 is accessed based on a combination of symbols (symbols of a dropped combination) obtained in the internal gain to determine which symbol to stop on the sub-drum 38. and then the control signal is sent to the control subcircuit 82 to stop at this symbol (step 817).

Then, the CPU 41 determines whether a predetermined time period has elapsed (whether the time period allowing the operation of the rotation speed change switch 101 has expired) (step 818). If the predetermined time period has not expired, the processing returns to step 818. The predetermined time period in step 818 is preferably from about 1 to 3 seconds. Preferably, the liquid crystal display device or the like displays whether the time period allowing the operation of the rotation speed change switch 101 has expired. In addition, the end of the time period for actuating the rotational speed change switch 101 can also be transmitted by voice through the speakers 21K, 218.

- 9 008395

The reason why the time period for the operation of the rotation speed change switch 101 is set in this way is that there are many cases where one looks at the effect on the sub drum and determines whether or not to operate the rotation speed change switch 101.

Then, the CPU 41 determines whether the rotation speed change switch 101 is actuated (step 819). That is, when the rotation speed change switch 101 is actuated for the aforementioned time period, the rotation speed change flag provided in the RAM 43 is set. In this case, the CPU 41 determines whether the rotation speed change switch 101 is actuated, determining whether or not in RAM 43 flag change the speed of rotation.

In the case where it is determined that the rotation speed change switch 101 is not actuated, the rotation speed is not changed, so that the processing is performed in accordance with step 822. On the other hand, in the case where it is determined that the change switch 101 is actuated speed, then the CPU 41 then determines, based on the above-mentioned specific effect table, whether a particular effect is shown by means of a symbol that is stopped / displayed on the sub drum 38 (step 820).

In the case where it is determined that a particular effect is not displayed on the sub drum 38, it is necessary to invalidate the rotation speed switch 101, so that the rotation speed change flag is cleared and processing is performed in accordance with step 822.

In the case where it is determined that a particular effect is displayed on the sub drum 38, the CPU 41 then changes the rotation speed of the main drum 38 to slow rotation based on the rotation speed change flag (step 821). In other words, the CPU 41 sends a control signal to change the intervals between the exciting pulses supplied to each of the stepper motors 59b, 59C, 59K, thereby reducing the rotation speed of the main drums 3 to low.

A particular effect refers, for example, to an effect that shows that the probability of an internal win for a particular symbol of a dropped combination is high. In FIG. 11A-11C show examples of effect symbols shown on a sub drum. The method of the effect (result) may be such as to contain a symbol of a pig finding treasures or relaxing in the tropics, as shown in FIG. 11A and 11B. Examples are given for internal winnings for OB, BB, watermelon and another symbol of a small combination, but the effect method in the present invention is not limited to these examples. For example, it is also possible to show specific characters or the like, or to show a specific character that has fallen out, or the like. It should be noted that in FIG. 11C shows an embodiment in which the combination of symbols on the main reels is not a win.

If there is a high probability that an internal gain has occurred for a particular symbol of a dropped combination, there is still a small possibility that an internal gain has not occurred for that particular symbol of a dropped combination. Therefore, in this case, for example, even when the combination of symbols of the main drum is not a gain, it is still necessary to establish a sub-drum results table in order to form a specific effect (result). However, this probability should be low, for example below 5%.

In the present invention, when the sub-drum 38 has generated this type of specific effect (result), the gain is for OB, BB, a symbol of a small combination or other symbol of a dropped combination, due to the line of specific symbols. However, it is difficult to line up the intended symbols, especially for a beginner. Therefore, the rotation speed of the main reels 3 is reduced, and thus it becomes easier to line up the symbols on the main reels by means of a check stop.

Then, the CPU 41 determines whether the stop switches 7 (7b, 7C, 7K.) Are turned on (stop buttons) based on whether there is an input signal from the drum stop signal circuit 56 (step 822). In the case where it is determined that the stop switch 7 is not turned on, the CPU 41 determines whether the value of the automatic stop timer is 0 (step 823). In the case where it is determined that the value is not 0, processing returns to step 822.

On the other hand, in the case where it is determined in step 822 that the stop switches 7 are turned on, or in the case where it is determined in step 823 that the automatic stop timer is 0, the CPU 41 stops the rotation of the main reels 3 in accordance with the stop switches 7 . When doing this, the number of moving frames is determined based on the query (symbol of the internal winning combination), symbol positions (rotation positions of the main reels 3 when the action is performed), the selected stop control table, and the like (step 824).

Then, the CPU 41 performs processing to stop the main reels 3 after forcing them to rotate the number of moving frames determined in step 824 (step 825), and sets a stop request for one of the main reels 3 (step 826).

Then, the CPU 41 determines whether all three main drums (3b, 3C, 3K.) Have stopped (step 827). In the case where it is determined that not all of the main reels have stopped, processing is returned to block 822.

Then, as shown in the game execution processing program 2 in FIG. 6, when it is determined that all the main reels have been stopped, the CPU 41 searches for a win (block 830). In this moment

- 10 008395 time CPU 41 refers to objects such as a table of combinations of win symbols that are stored in ROM 42. In addition, CPU 41 also determines whether or not the win flag is normal, and if not, an error about prohibition and processing may be suspended.

The CPU 41 determines whether there is a payout of coins, that is, say, it determines the presence / absence of the number of winning coins (step 831). In the case where it is determined that there is a payout of coins, the CPU 41 either saves or pays out the number of coins determined in accordance with the state of the game and the symbol of the winning combination (step 832). In the case where the coins are to be saved, the CPU 41 executes the processing to sum up the number of coins stored in the RAM 43. On the other hand, in the case that the coins are paid out, the CPU 41 sends a payout command signal to the coin collecting drive circuit 51 and the predetermined amount of coins is paid out of the coin collector 50. When this is done, the coin determination unit 508 adds the number of coins to be paid out from the coin collector 50. When the total amount reaches the indicated number, a signal to complete the payment of coins is entered t in the CPU 41. Accordingly, the CPU 41 stops the actuation of the coin collector 50 by the coin collector drive circuit 51 and completes the coin payout processing.

Then, the CPU 41 determines whether the OB gain has actually occurred (step 833). In the event that an OB gain has occurred, the CPU 41 performs OB settings (step 834). At the same time, at step 834, the CPU 41 performs settings in the probabilistic lottery table OB and the table of combinations of win symbols for OB. In addition, in this case, at step 834, the CPU 41 starts summing the number of winnings of the games OB and the like and starts processing to display the value of the total amount on the display unit 20 of the number of additional games.

In the case where the processing corresponding to step 834 is performed or when it is determined at step 833 that the OB gain has not occurred, the CPU 41 determines whether the BB gain has occurred (step 835). When it is determined that a gain in the BB has occurred, the CPU 41 performs BB tuning (step 836). At the same time, at step 836, the CPU 41 performs the settings in the table of probabilistic lottery BB and in the table of combinations of win symbols for the BB. In addition, in this case, at step 836, the CPU 41 starts the summation of the number of used games of the BB and the like, and starts displaying the value of the total amount thereof on the display unit 20 of the number of additional games, and starts the summation of the paid coins and the like.

In the case when the processing corresponding to step 36 is performed, or when it is determined at step 835 that the gain of the BB has not occurred, the CPU 41 determines whether the OB has ended (step 837). In the case where it is determined that the OB has completed, the CPU 41 then performs processing to reset / clear the OB setting (step 838). At the same time, at step 838, the CPU 41 uses the table of probabilistic lottery OB, which was established during processing at step 834, the table of combinations of winning symbols for OB and the like, to perform processing to switch to the table of probability lottery used for the state of a normal game (not OB or BB).

In the case where the processing corresponding to step 838 is to be performed, or when it is determined at step 837 that the winning OB has not completed, then the CPU 41 then determines whether the BB has ended (step 839). In the case where it is determined that the WB has completed, the CPU 41 then executes processing to reset the WB settings (step 840). At the same time, at step 840, the CPU 41 uses the BB probability lottery table that was set during processing at step 836, a table of combinations of winning symbols for the BB, etc., to perform processing to switch to the probability lottery table, which should be used in the state ordinary game.

In the case where the processing corresponding to step 840 is to be performed, or when at step 839 it is determined that the BB has not completed, the CPU 41 then clears the rotation speed change flag and sets the settings for restoring the normal rotation speed of the main drums (step 841). Therefore, in a subsequent game, the main reels will rotate at a normal rotation speed if the rotation speed change switch 101 is not actuated. If the processing in step 841 is completed, then this routine ends.

The following is a simple explanation regarding the gaming method of the gaming machine according to the first embodiment. First, the player performs actions such as inserting coins, and actuates the start lever to start the rotation of the main reels and the sub drum. As soon as the main drums and the sub-drum have started to rotate and a predetermined period of time has elapsed, the sub-drum stops at a symbol that shows a combination of a pre-set effect (result).

In FIG. 11A-11C show examples of combinations of effects (results) displayed on a sub drum. As shown in FIG. 11A-11B, when the symbol of a piglet discovering treasures, or relaxing in the tropics, or the like is displayed, it indicates that there is a high probability that there has been an internal win for OB, BB, watermelon or other small combination symbol. On the other hand, when the pig cries, as in FIG. 11C, this indicates that there is a high probability of a non-winning symbol.

In the case where the effect (result) symbol displays a specific result, such as that shown in FIG. 11A and 11B, then a player who believes that this indicates a high probability of internal you

- 11 008395 games for a specific symbol of the combination that has fallen, and who wants to make the symbol he has planned to stop and be displayed, or the beginner will activate the switch 101 changes the speed of rotation.

When the aforementioned result indicates an internal gain for a particular symbol of the dropped combination, the operation of the rotation speed change switch 101 causes a decrease in the rotation speed of the main reels, and thus the player can execute a control stop more easily and can line up the combination of symbols that he plans. However, even with the same symbols, the main reels may not have an internal gain for a particular symbol of the dropped combination, in which case the rotation speed of the main reels is not reduced.

Therefore, instead, when the player actuates the rotation speed change switch, the player can make a judgment whether the particular symbol of the dropped combination coincides internally, based on whether the rotation speed of the main reels has been reduced.

Then, stop switches are actuated to stop the rotation of the main reels in a combination displaying a combination of predetermined symbols.

The gaming machine according to the present invention in accordance with the first embodiment is created as described above. Therefore, it is possible to actuate the rotation speed change switch in order to slow down the rotation speed of the main reels only when it is indicated that there is a high probability of an internal gain for a particular symbol of the dropped combination. In any other case, the rotation speed of the main reel is not reduced, and in this way it is possible to maintain the usual level of significance of the skill and maintain the initial attractiveness of the gaming machine.

In addition, when the rotation speed changes are activated by the switch and the rotation speed of the main reels is slowed down, the likelihood of placing the combination of the intended symbols in the line increases, the chance of winning coins increases, and, moreover, the use of a sub drum increases the efficiency. As a result, it becomes possible to fully enjoy the game using the gaming machine.

Second Embodiment

An explanation is given below regarding a gaming machine according to the present invention in accordance with a second embodiment. The gaming machine according to the second embodiment is further provided with a point award means to award a predetermined number of points when the predetermined condition is satisfied, a point subtractor to subtract the predetermined number of points when the aforementioned rotation speed change switch is actuated, and a means for storing points in order to save the full amount of points, based on the results of operations through the above media Twas the awarding of points and the above-mentioned means for subtracting points. The aforementioned rotation speed change switch becomes operable when, in addition to the symbols on the sub-drum displaying this particular effect (result), the number of points stored in the aforementioned point storage means is equal to or greater than the number of points that will be subtracted by the aforementioned means of subtracting points.

In FIG. 7 is a front view showing the appearance of the gaming machine of the present invention in accordance with the second embodiment. In FIG. 8 is a block diagram showing a main control circuit, peripheral devices and the like constituting a gaming machine according to the present invention in accordance with a second embodiment.

The gaming machine in accordance with the second embodiment is equipped with a block 201 display points for displaying the number of points located on the right side in the middle region of the block (part) 2A of the display panel. Other than this, the structure is substantially similar to the gaming machine according to the first embodiment shown in FIG. 1-2. Furthermore, in the block diagram shown in FIG. 8, the indicator control circuit 58 is equipped with a glasses display unit 201. Other than this, the structure is substantially similar to the gaming machine according to the first embodiment shown in FIG. 1-2. Therefore, the explanations are omitted in this case, with the exception of the explanation of the glasses display unit.

The point display unit 201 is a display device for displaying on the screen the number of points saved by the point saving means (point counter) of the RAM 43. The number of points is increased by a points or by b points when a win occurs for a particular symbol of a small combination, a symbol of a restart combination or like that. That is, a gain for a particular symbol of a small combination, a symbol of a restart combination or the like leads to the fact that the numerical value in the display units of the points has become a numerical value of P = P + a or P = P + b. On the other hand, when the rotation speed change switch is actuated and the rotation speed of the reels is reduced, items A are subtracted. That is, the number of points shown in the points display unit becomes the value PA. The number of points cannot be negative. When the P value is less than A, the rotation speed change switch 101 cannot be operated to reduce the rotation speed of the main drums. Therefore, the player must act as a switch

- 12 008395 changes in rotational speed at that moment in time when the effect of decreasing the rotational speed of the main drums is greatest.

As described above, the gaming machine according to the second embodiment is characterized in that it provides a point award means to award a predetermined number of points in the case when the predetermined condition is satisfied, a point subtractor to subtract the predetermined number of points in the case where the action of the aforementioned rotation speed change switch, and the means for storing points to save the total amount of points based on the results of operations of the above means of awarding points and the above-mentioned means for subtracting points. In addition, this embodiment is characterized in that the aforementioned rotation speed change switch becomes operable when, in addition to the condition required in the gaming machine corresponding to the aforementioned first embodiment, the number of points stored by the aforementioned means of storing points is equal to or greater than the number points to be deducted by the aforementioned means of deducting points. This is explained using flowcharts.

In FIG. 9-10 are flowcharts illustrating routines that are executed in a gaming machine according to the present invention in accordance with a second embodiment. It should be noted that when performing the same processing as in the gaming machine according to the present invention in accordance with the first embodiment, the same step numbers are used, and detailed explanations are omitted for the steps that perform the same processing.

First, as shown in the game execution processing program 1 of FIG. 9, steps 810-820 perform the same processing as in the gaming machine according to the present invention in accordance with the first embodiment.

In other words, the processing corresponding to steps 810-815 is performed. At step 816, the CPU 41 determines whether a predetermined time period has elapsed. At step 817, the sub drum is stopped. At step 818, it is determined whether the time period for which the rotation speed change switch 101 is allowed to operate has expired. In addition, the CPU 41 determines in step 819 whether the rotational speed change switch 101 is actuated, and in step 820 determines whether there is a specific result on the sub drum.

When there is a specific effect (result) on the sub drum, the CPU 41 then determines whether the number of points (P) stored by the point storage means (point counter) in RAM 43 from steps 853 and 855 from the previous game is equal to or greater than a predetermined value ( A), in other words, is P> A (step 850). It should be noted that the processing in steps 853 and 855 are explained below.

If the number of points (P) stored by the means for storing points is not equal to or greater than the set value (A), in other words, when it is determined that the number of points (P) is less than the set value (A), then the action must be invalidated a rotational speed change switch 101, so that the rotational speed change flag is cleared, and processing proceeds to step 822.

On the other hand, when it is determined that the number of points (P) stored in the point counter is equal to or greater than the set value (A), the CPU 41 then changes the rotation speed of the main reels 3 to slow rotation based on the flag for changing rotation speed (step 821). In other words, the CPU 41 sends a control signal to change the interval between pulses output to each of the stepper motors 59b, 59C, 59B, and thus reduces the rotation speed of the main drums 3 to low. In the aforementioned case, there is a specific effect (result) on the sub drum and P> A, so that the control stop is easy and the gain easily occurs for a particular symbol of the internal winning combination.

Then, the CPU 41 subtracts the number A of points from the number of points (P) stored in the point counter in response to a change in the rotation speed of the main reels, in other words, P = PA, and this value is stored in the point counter (step 851).

The subsequent processing from step 822 to step 841 is performed in a manner similar to the gaming machine according to the present invention in accordance with the first embodiment, so that explanation is omitted.

At step 841, in the game execution processing program 2 shown in FIG. 10, after setting the parameters for restoring the normal rotation speed of the main reels 3, the CPU 41 determines whether a win has occurred with the restart symbol combination (step 852).

In the case where it is determined that a win has occurred for the replay combination symbol, the CPU 41 then adds the number of points a to win the replay combination symbol to the number of points (P) in the point counter and stores it (step 853). In other words, the number of points in the score counter becomes P = P + a.

On the other hand, in the case where it is determined that a win did not occur for the restart symbol, or the number of points in the score counter became P = P + a, the CPU 41 then determines whether the guessing of the small combination symbol has occurred (step 854).

- 13 008395

In the case where it is determined that a small combination symbol is winning, the CPU 41 then adds the number of b points of winning the small combination symbol to the number of points (P) in the point counter (step 855). In other words, the number of points in the score counter becomes P = P + b. The number of points may vary depending on the winning type of symbol of a small combination and the state of the game. The player remembers (means) the glasses that are displayed as described above, and then, when there is a specific effect (result) on the sub drum at 820, the player determines whether to activate the rotation speed change switch. When the processing at step 855 is completed, then this routine ends.

The following is a simple explanation regarding the game method of the gaming machine in accordance with the second embodiment. First, the player performs actions such as introducing coins. After that, the player then actuates the start lever to start the rotation of the main reels and the sub drum. Once the main drums and the sub-drum have started to rotate and a predetermined period of time has elapsed, the sub-drum stops at a symbol that shows a predetermined combination of an effect (result) such as that shown in FIG. 11A-11C.

When an effect (result) symbol is displayed as a specific result, such as that shown in FIG. 11A and 11C, the player checks the number of points P displayed in the points display units 201 on the indicator panel.

The number of points P is increased by a or b, depending on the occurrence of a small combination symbol and the like, and thus indicate the current points after subtracting A when the rotation speed change switch is actuated to reduce the speed of the main reels. If the number of points P is less than A, then the rotation speed of the main reels cannot be reduced. On the other hand, if P is equal to or greater than A, then a rotation speed change switch can be operated to reduce the rotation speed of the main drums.

When the number of points P is equal to or greater than A, the player who believes that this indicates a high probability that a particular symbol of the guessed combination coincides internally, and who wants to make the intended symbol to stop and be displayed, or the beginner will activate the speed change switch rotation.

In the case where the aforementioned effect (result) indicates that a particular symbol of the dropped combination has coincided internally, the operation of the rotation speed change switch decreases the rotation speed of the main reels. Thus, the player can execute a control stop more easily and can put in line the combination of symbols that he has outlined (symbols of the dropped combination).

The gaming machine of the present invention in accordance with the second embodiment is created as described above. Therefore, for example, the rotation speed change switch is effective only when the value after adding the number of points awarded when the so-called restart symbol or small combination symbol matches is greater than the number of points that will be subtracted if the aforementioned speed change switch is activated rotation. Therefore, the rotation speed change switch cannot always be activated to slow down the rotation speed of the main drums. For each player, it becomes necessary to evaluate the corresponding time points in order to control the rotation speed change switch. Therefore, the contents of the game becomes changeable and the game can be enjoyed to a greater extent.

Third Embodiment

The following is an explanation of a third embodiment of the present invention. The gaming machine according to the third embodiment is a gaming machine in which the game described in the first and second embodiments is applied to a bonus game.

The gaming machine according to the third embodiment shares many features like the gaming machine according to the first embodiment shown in FIG. 1-6, and the second embodiment shown in FIG. 7-11, so detailed explanations of these features are omitted here. Only features that are excellent are explained in more detail. Moreover, in FIG. 12 is a perspective view showing an appearance of a gaming machine according to the present invention in accordance with a third embodiment. Namely, the gaming machine 300 in accordance with the present embodiment is equipped with a housing 312 and a main door 350.

The surface of the housing 312, which is facing the player, is open, and the housing 312 is set at a predetermined location, for example, in a casino. The housing 312 is provided with a control device described below for electrical control of the gaming machine 300, and a coin collector, not shown in the diagrams, for controlling the introduction, storage and payment of coins, and other various structural structures.

The main door 350 is a structure occupying the inner part of the housing 312, so that it is not exposed from the outside (it is not open from the outside). The main door 350 is hinged on the left side when viewed from the front of the cabinet 312.

- 14 008395

The hinge is used as a fulcrum, and the door 350 can be rotated in a circle forward and backward, whereby it can be opened and closed freely. A liquid crystal display device 330 is provided approximately in the center of the main door 350.

The liquid crystal display device 330 is a means for displaying various symbols corresponding to a game, including effects (results) images, information images and the like. The player views the various images displayed on the device.

330 liquid crystal display as it plays. The liquid crystal display device 330 is equipped with a transparent liquid crystal panel. On a liquid crystal panel, part of the panel or the entire panel can be switched between transparent / opaque states (the switching is determined by whether or not the device 330 is controlled by the liquid crystal display). The liquid crystal display device 5 also allows display of various images.

On the side of the rear surface of the liquid crystal display device 330, there are three mechanical main drums arranged adjacent to each other, on the peripheral surface of each of which various types of symbols are located. In addition, on the right side there is a mechanical sub-drum that can rotate, on the periphery of which there are various types of symbols that differ from those on the main reels. Different symbols on each of the mechanical drums (main and sub drum) can be observed when the liquid crystal panel is in a transparent state. The designs of each of the mechanical drums (main drums and sub drum) are essentially similar to each of the mechanical drums (main drums and drum) in the first embodiment described above, so that detailed explanations thereof are omitted. It should be noted that the gaming machine for the present invention is not limited to three main reels and one sub drum; the combination of quantities can be changed as needed.

Below the liquid crystal display device 330, an essentially horizontal control panel 328 is provided. An element is provided on the right side of this control panel 328

331 for lowering coins, in order to enter coins into the gaming machine 300. On the other hand, on the left side of the control panel there is a bet switch 322 for selecting a number of coins in order to bet on the activated line, which is described below. Also provided is a re-bet switch 324 when repeating rotation to execute the game again without making any changes to the coin bet on the aforementioned activated line in the previous game. The number of coins to bet on the aforementioned activated line is determined according to whether the bet switch 322 or the re-bet switch 324 is pressed / activated.

On the aforementioned control panel 328 to the left of the bet switch 322, a trigger switch 332 is provided. Pressing / activating either the start switch 332 or the spin repeat bet switch 324 is used as a start to start a game, and the rotation of the above three mechanical reels starts in a predetermined manner.

On the other hand, on the aforementioned control panel 328, a payout switch 336 is provided close to the coin drop member 331. When the player presses / operates the payout switch 336, the coins that have been entered are paid out from the payout hole 338, which is open on the front bottom of the door 350. The coins that are paid out are collected in the coin container 340. Above the coin container 340, framing the left and right side of the coin payout opening 30, speakers 342 are provided for transmitting sound effects that emanate from speakers placed inside the cabinet 312, outside the cabinet 312.

It should be noted that, although this is omitted from the diagrams, various display units are provided at predetermined positions on the door 350, including a payout display unit, a loan amount display unit, and a bet amount display unit.

In addition, in the present gaming machine 300, five paylines b1 (corresponding to the center line 8a in FIG. 1), b2 (corresponding to the top line 8b in FIG. 1), b3 (corresponding to the bottom line 8c in FIG. 1), b4 (corresponding the intersection line 86 in Fig. 1) and b5 (corresponding to the intersection line 8e in Fig. 1) are displayed on a transparent liquid crystal panel of the liquid crystal display device 330. The display combinations of these pay lines L-L5 are basically similar to each of the lines 8a-8e in the first embodiment, so that detailed explanations are omitted.

In addition, in the present gaming machine 300, the rotation speed switch 301 and stop switches 307b, 307C, 307B are provided on the control panel 328, which are similar to the rotation speed switch 101 and the stop switches 7b, 7C, 7B in the aforementioned first embodiment.

The rotation speed switch 301 and the stop switches 307b, 307C, 307B have similar functions with the rotation speed switch 101 and the stop switches 7b, 7C, 7B. Therefore, detailed explanations are abridged. However, in the present gaming machine 300, the switch actions

- 15 008395

301 rotation speeds and stop switches 307b, 307C, 307K are activated after switching to the premium game. During a normal game, they are inactive (non-working). This is a difference from the rotational speed switch 101 and the stop switches 7b, 7C, 7K described above. In other words, in this regard, the present gaming machine 300 is significantly different from the gaming machines corresponding to the aforementioned first and second embodiments. It should be noted that the rotation speed switch 301 and the stop switches 307b, 307C, 307K are not limited to the examples shown in FIG. 12. They can be provided at other positions on the housing 312. It also goes without saying that they can be touch panels displayed on the transparent display panel of the liquid crystal display device 330.

It should be noted that it is also possible to have only a portion of the indicator screen of the aforementioned liquid crystal display device 330 indicated as an area that is switched between the transparent / opaque state. In addition, the full screen of the indicator can also be indicated as an area whose state is switched between transparent / opaque.

The control device for the present gaming machine 300 is made essentially substantially similar to the control device shown in FIG. 3 (or with the control device shown in FIG. 8). However, the command signal for changing the rotation speed, which is output in the case when the rotation speed switch 301 is pressed / actuated, and the drum stop signal, which is output in the case where the stop switches 307b, 307C, 307K are pressed / actuated, are set as Valid only during the bonus game. In addition, in the control device 12 shown in FIG. 3 and 8, input signals for the speakers 21b, 21K and the liquid crystal display device 5 are input from the input / output port 48 of the main control circuit 81 through the control subcircuit 82. However, the control device of the present gaming machine 300 is not equipped with a control subcircuit. Thus, the signal from the input / output port of the main control circuit 81 is input directly to the speakers and the liquid crystal display device 330.

In FIG. 13 and 14, basic processing programs for controlling the gaming machine 300 are illustrated, which are executed by the control device of the present gaming machine 300 described above.

Turning to FIG. 13, in the main processing program, the CPU of the control device first determines whether there is a remaining credit, which is the remaining number of coins entered (step 8101). In particular, the CPU reads the amount of C credits stored in RAM and performs the aforementioned determination operation based on the read amount of C credits.

Going to step 8102, the CPU determines whether the bet betting repeat switch 324 is pressed / activated (step 8102). In the case where the repetition switch 324 when repeating rotation is pressed and the operation signal is input from the switch 324, the CPU moves the processing to step 8114. On the other hand, in the case where the operation signal from the repetition switch 324 when repeating rotation is not yet entered even after the predetermined time period has elapsed, the CPU then determines that the switch 324 is not pressed, and then transfers the processing to step 8103.

When the processing proceeds to step 8103, the game conditions are set. Specifically, based on the operation of the bet switch 322, the CPU determines the number of coins that will be the bet for the activated L-L5 lines in the current game. At this time, the CPU receives an operation signal that emanates from the bet switch 322 due to the operation of the switch 322, and based on the number of times that this received signal is received, the CPU stores the bet amounts for the above-mentioned lines L1-L5 in certain areas of RAM memory. The CPU reads the amount of C credits, which is recorded in a specific memory area in the aforementioned RAM. From the readout amount C of the loan, the CPU then deducts the amount of the total rate, which is formed by adding the aforementioned rate amount. This value, which is subtracted, is then stored in a specific area in RAM.

If the game conditions are set, the CPU then waits for the trigger switch 332 (step 8104) to be activated. In the case where the start switch 332 is pressed, which causes the operation signal to be input from the switch 332, the CPU determines that the start switch 332 is activated and transfers the processing to block 8105.

On the other hand, if the processing proceeds to step 8114, the CPU determines whether the value C of the loan amount is equal to or greater than the total bet amount from the previous game. In the event that it is determined that the aforementioned value C of the loan amount is lower than the full value of the bet amount of the previous game, the game cannot be started, so that the CPU completes the present program without performing any processing. On the other hand, if it is determined that the aforementioned value C of the loan amount is equal to or greater than the total bet amount from the previous game, the CPU subtracts the full value of the bet amount of the previous game from the value C of the loan amount and stores the subtracted value in a specific memory area in RAM After that, the CPU transfers processing to step 8105.

When the processing proceeds to step 8105, the CPU performs processing to determine a winning combination symbol by the internal lottery.

When the aforementioned lottery processing is completed, the CPU then moves the processing to step

- 16 008395

8106.

As shown in FIG. 13, when the processing proceeds to step 8106, the CPU rotates the mechanical main reels. Specifically, the CPU causes each of the mechanical reels to rotate sequentially or simultaneously based on a symbol location table stored in the aforementioned RAM.

When the rotation of the mechanical main reels is started, the CPU then waits for the predetermined time period to expire (step 8107). When the predetermined time period has elapsed, the CPU then stops the rotation of each of the mechanical main drums (block 8108).

When the rotation of all the mechanical main reels has stopped, the CPU then determines whether the winning combination symbol has fallen out (step 8109). Specifically, the CPU performs determination processing based on the status of the win flag. If the win flag is not turned on, the CPU determines that the symbol of the winning combination does not take place, and then ends this processing. On the other hand, when the CPU determines that the win flag is turned on, the CPU determines that the winning combination symbol has occurred, and transfers the processing to block 8110.

When the processing proceeds to block 8110, the CPU then determines whether the winning combination symbol that takes place is a combination symbol that enables transition to the bonus game. In particular, the CPU performs the aforementioned processing corresponding to the determination based on the type of the aforementioned win flag. In the case where the winning flag is on, the flag indicating that the player has won the transition to the aforementioned bonus game, the CPU determines that the winning combination really indicates the transition to the bonus game, and then transfers the processing to step 8111. On the other hand, in the case where the checkbox turned on is not a flag indicating the transition to the aforementioned bonus game, the CPU determines that the winning combination is a symbol of the winning combination for something other than the transition to the bonus game, and translates about rabotku to step 8113.

When the processing proceeds to step 8111, then the CPU pays out in a predetermined manner the number of coins suitable for the combination symbol allowing entry into the bonus game mentioned above.

After completion of the payment initiated by the combination symbol enabling entry into the bonus game, the CPU then performs processing corresponding to the bonus game (block 8112). Such a bonus game is, for example, a game that can be launched for a predetermined number of games without betting coins (free game). The present embodiment, for example, is set so that a free game can be played 15 times. When executing processing for a premium game, the CPU first activates the rotation speed switch 301 and the stop switches 307b, 307C, 307B. In addition, the CPU reads the credit amount C recorded in a predetermined memory area in the aforementioned RAM, and adds to this value a certain number of coins determined by winning the bonus symbol PREMIUM (ΒΟΝυ8), and then stores this value in the preset memory area in RAM . The CPU then reads the bonus game lottery table and the winning combination table that are stored in the ROM, and then writes the bonus game lottery table and the winning combination table that read again the main game lottery table and the winning combination table that are stored in the aforementioned predetermined RAM memory area . In the aforementioned bonus game lottery table, the odds of guessing the combination symbols are set higher than in the aforementioned main game lottery table. The CPU stores data indicating a predetermined number of bonus games (which is 15 in the present embodiment) in a predetermined RAM memory area (this corresponds to the processing for setting the number Ν of bonus games in step 8201, which is described below). Accordingly, when the bonus game has started, for example, the player intends to launch a game in which winning combination symbols occur easily during 15 games, thereby increasing the player’s interest in the game.

When the processing intended for the bonus game is completed, the CPU terminates this main processing program.

On the other hand, when processing proceeds to step 8113, the CPU pays out in a predetermined manner the number of coins suitable for the winning combination symbol other than the aforementioned winning combination symbol enabling entry into the aforementioned bonus game.

After the payout is completed for the winning combination symbol other than the winning combination symbol enabling entry into the bonus game, the CPU then completes this main processing program.

It should be noted that in each payment processing mentioned above, the number of coins to be paid is stored as a loan. However, the payout command may be issued to the coin acceptor drive (initiation) circuit in order to cause the payout of the coins, in fact, from the payout hole 338 through the coin acceptor.

Then, as shown in FIG. 14, in the bonus game processing program, the CPU first sets the number Ν of bonus games, as described above (step 8201).

- 17 008395

When the number N of bonus games is set, the CPU performs processing to determine a winning combination symbol by the internal lottery (block 8202).

Then, when the processing proceeds to step 8203, the CPU causes each of the mechanical main reels to rotate either sequentially or simultaneously based on the symbol location table stored in the above RAM.

Thereafter, each processing that is explained in steps 816-827 in the aforementioned first embodiment is performed, and a control intended for processing to change the rotation speed of the mechanical main drums is performed, but this part is similar to the description of the first embodiment described above, so that detailed explanation omitted.

When the rotation of all the mechanical main reels is stopped, the CPU determines whether the winning combination symbol is present based on the status of the win flag (step 8206). When the win flag is turned on, the CPU determines that the winning combination symbol does occur. Then, the CPU calculates the amount of coin payout corresponding to the winning combination symbol, and pays out the calculated number of coins in a predetermined manner (step 8207).

Then, the CPU performs processing to restore the normal rotation speed of each of the mechanical main drums (step 841), but this processing is similar to the explanation of step 841 given in the first embodiment, so that a detailed explanation is omitted.

After that, the CPU passes the processing to block 8208. On the other hand, in the case when the win flag is not turned on, the CPU determines that the winning combination symbol has not occurred. The CPU then transfers the processing to block 841 without performing the aforementioned payout processing, and then performs the processing in block 8208.

When the processing proceeds to block 8208, the CPU reduces the number N of bonus games.

When the number of bonus games N is reduced, the CPU determines whether any game from the number of bonus games N is left. In the event that some of the number of bonus games N remains, the CPU returns processing to block 8202 and performs lottery processing. On the other hand, in the case where the bonus game N does not remain, the CPU invalidates the rotation speed switch 301 and the stop switches 307C 307C, 307B (block 8210) and then terminates this bonus game processing program.

It should be noted that in the aforementioned payout processing, the number of coins to be paid is stored as a loan. It is possible to wait for the payout command to the coin acceptor drive circuit so that the coins are actually paid out from the payout hole 338 through the coin acceptor.

In addition, it goes without saying that various traditionally known free game contents can be used as the contents of a free game, which is given as a premium game.

It should be noted that the aforementioned third embodiment is explained based on the first embodiment. However, instead, the structure may be based on the second embodiment, in which means for storing points and means for subtracting points are provided.

In addition, in the aforementioned third embodiment, the fact whether or not a winning combination symbol has occurred has been determined during the bonus game according to the timing of pressing / actuating the stop switches 307C 307C, 307B. However, it is also possible to adopt a structure in which the appearance of the winning combination symbol is not a controlled moment of time for pressing / activating the stop switches 307C 307C, 307B.

Stop switches 307b, 307C, 307B can simply function as dummy ones, with the appearance of a winning combination symbol, determined solely in accordance with the internal lottery.

In addition, in the third embodiment, the main drums and the sub-drum are created in the form of mechanical drums. However, they can also be created as so-called video drums displayed on the screen of the aforementioned liquid crystal display device 330 or the like.

The gaming machine according to the present invention in accordance with the third embodiment is created as described above. Thus, the rotation speed change switch can be used to slow down the rotation speed of the main reels only when, for example, a result on the aforementioned sub-drum and the like during a bonus game indicates a high probability that there has been an internal win for a particular symbol of the dropped combination. At this point, the likelihood of placing the intended combination of symbols in a line increases and the chance of winning coins during the bonus game increases, whereby the player’s sense of expectation of the bonus game can be raised even further, thereby increasing efficiency.

It should be noted that the gaming machine according to the present invention is explained in specific terms based on the gaming machines in accordance with the respective embodiments in the first, second and third embodiments. However, the present invention is not an ogre.

- 18 008395 by the above mentioned gaming machines, provided that the structures and results of the present invention are present.

In the above embodiments, explanation is given regarding the case where there is one sub drum, but the number of sub drums is not limited. There may be two or more than two sub-drums. In addition, glasses can be displayed on a liquid crystal device.

The times at which the rotation speed change switch act may be before the start switch operation. In this case, the player operates the rotation speed change switch based on the displays of the results of the previous game, so that the CPU also determines whether the operation to change the rotation speed is valid based on the displays of the results of the previous game.

In addition, the condition for enabling the rotation speed of the aforementioned main drums to be changed is not limited only to the displayed combination corresponding to the sub drum. It is also possible to establish a condition establishing a means other than a sub drum. For example, an indicator or the like can be provided at a position located somewhere on the gaming machine body (a position visible to the player, for example, on the front surface panel or on the upper surface of the cabinet), and the condition can be satisfied if this indicator or the like is highlighted or flickers at a predetermined point in time or a predetermined color. Furthermore, the condition can also be satisfied if a predetermined character is displayed on the screen of the liquid crystal display device or the like.

In addition, the change in the rotation speed of the main drums is not limited to only two levels and can be set at three levels or more. In addition, the aforementioned number of points to be used can be set to a plurality of levels, and the number of points to be used can be applied as appropriate. Also, the type of team (the signal of the team, which can be perceived by visual perception, auditory sensations or the like) as premises for spending points can be arbitrary.
