Description

  The present invention relates to a gaming machine that performs slip control when rotation of a reel is stopped, a data management method for compressing and storing a plurality of slide frames set in one reel, and data management for realizing this data management method In particular, the present invention relates to a gaming machine, a data management method, and a data management program that can compress the number of smooth frames to 6 bytes in binary notation.

In general, a slot machine (rotating type gaming machine) is known as a gaming machine installed in a game arcade.
In the slot machine, a player inserts a game medium and operates (presses) a rotating rotation start device (start lever) to design a predetermined pattern, character, number, or the like (hereinafter collectively referred to as “pattern”). A plurality of (usually three) reels (rotating cylinders) displaying the symbol start rotating, and the rotation stopping device is activated by pressing a plurality of (usually three) stop buttons corresponding to each reel at an arbitrary timing. This is a gaming machine in which the reels that are activated to rotate are stopped, and a predetermined number of game media are paid out according to the arrangement of the symbols of the stopped reels.

In such a slot machine, rotation stop control called slip control is performed when the rotating reel stops.
The slip control includes pull-in control and kick-off control.
Withdrawal control is to detect the symbol displayed on the winning line at the timing when the stop button is operated, and when this detected symbol is different from the winning symbol for winning the gaming state won in the internal lottery, The control means that the reel is rotated (displaced) by several frames so that the winning symbol stops on the winning line.
On the other hand, in the kicking control, when the detected symbol is a symbol for winning a gaming state that is shifted in the internal lottery, the reel is rotated (displaced) by several frames so that the winning symbol does not stop on the winning line. Refers to control.

Further, as a method for realizing the slip control, for example, there is a table control performed using a slip frame number table.
A specific example of the smooth frame number table is shown in FIG. As shown in the figure, in the sliding frame number table, the number of sliding frames for each reel and each symbol (the number of displacement frames when the reel is displaced by several frames when sliding control is executed (the number of displacement symbols)). Is preset.
This smooth frame number table is used as follows.
When the stop button is operated, the symbols displayed on the winning line are detected at the timing of this operation. Next, the number of smooth frames corresponding to the detected symbol is specified using the smooth frame number table. Then, the reel is rotationally controlled to stop so that a symbol at a position displaced by the specified number of smooth frames is displayed on the winning line.

A specific example will be described.
For example, in the number of smooth frames shown in FIG. 13, the number of smooth frames “1” is set for symbol number 18 of the first reel. This means that when the detected symbol is symbol number 18, symbol number 19 shifted by “1” is displayed on the winning line and the reel is stopped.
Further, for example, the number of smooth frames “4” is set in the symbol number 15 of the first reel. This means that when the detected symbol is symbol number 15, symbol number 19 shifted by “4” is displayed on the winning line and the reel is stopped.
Thus, in the table control, the slip control is performed based on the number of smooth frames set for each symbol.

  By the way, the number of sliding frame tables is usually prepared as several hundreds of sliding pattern tables. This is because there are many types of winnings, including BB (Big Bonus Game) and RB (Regular Bonus Game), and even if the symbols displayed on the winning line when the stop button is operated are the same for each game. This is because it is possible to give the player an unexpectedness and to make the player entertained by displacing with a different number of smooth frames.

In addition, the amount of data in the case where one sliding pattern table is stored in the storage means is conventionally 21 bytes per reel.
This is because the number of smooth frames set for one reel is 21, and each number of smooth frames is any number from 0 to 4, and can be expressed by 1 byte.

However, the capacity of the storage means (memory) in which the smooth frame number table is stored is limited by rules. For example, the related enforcement law (the so-called Unit 5 regulations) amended in 2003 regulates it to 3 kB or less. In addition to the smooth frame number table, various data relating to the game are stored in the storage means. As the game performance improves in the future, it is desired to store more data or increase the sliding pattern table.
Therefore, if the data amount for one slip pattern table can be reduced as much as possible, the data amount of the entire hundreds of kinds of slip pattern tables can be considerably reduced, and a large free space can be created in the storage means.

Against this background, various techniques for compressing the data amount of the number of smooth frames have been proposed.
For example, a slide frame number table (advance frame number stop table) for the left reel and stop data (data indicating a stopped / non-stop state) set for each symbol of the left, middle, and right reels Some devices perform slip control using a simple stop table that is represented (see, for example, Patent Document 1).
In this technique, in the slip control, the number of bitter stops (number of smooth frames = 0) and the same symbol stop which is 4, 3, 2, 1, 0 in the order of appearance of symbols are most frequently performed. Focusing on the fact that there is regularity in that the control that is not stopped by this symbol is performed up to 4 times in the stop, creating and storing a simple stop table in addition to the smooth frame number table to reduce the data It is.

  In this case, the number of smooth frames is set to a number of 15 or less (numbers represented by 4 bits “0000” to “1111”), and two types of the number of smooth frames are set in one symbol. Since the data is represented by 1 byte, the data amount per reel can be 21/2 = 10.5 bytes.

Other conventional examples include the following.
Since the number of smooth frames can be represented by five of “0”, “1”, “2”, “3”, “4”, these are represented by 3 bits “000” to “100”, 3 bits × 21 There is a design in which the data amount per reel is 8 bytes, with the design = 63 bits.

Further, other conventional examples include the following.
Multiply 32 by the number of sub-frames of symbol number X on the first reel to obtain the first product, multiply the number of sub-frames of symbol number X on the second reel by 5 to obtain the second product, and then the third reel The number obtained by adding the first product and the second product to the number of sliver frames of symbol number X is used as the sliver number compressed data of symbol number X ("symbol number X" Common number) (for example, see Patent Document 2).
Specifically, for example, in the number of smooth frames shown in FIG. 13, for the symbol number 20 represented by a thick frame, the number of smooth frames “1” on the first reel is multiplied by 32 to obtain the first product “32”. The second reel “1” is multiplied by 5 to obtain a second product “5”, and the third reel “1” is multiplied by the first product and the second product. The sum “38” obtained by the addition (“26” in hexadecimal notation) is used as the compressed frame number compressed data of symbol number 20.

According to this technology, the calculated smooth frame number compressed data can be represented by 1 byte (8 bits), of which the upper 3 bits represent the number of subframes of symbol number X of the first reel, and the lower 5 bits represent the first. This represents the number of smooth frames of the symbol number X of the second reel and the third reel.
The compressed frame number compressed data represents the number of 3 frames of 3 symbols in 1 byte, and since 21 symbols are drawn on each reel, the compressed frame number data of 3 reels is 1 Byte × 21 pieces = 21 bytes data amount, and the number of smooth frames per reel can be compressed to 21 bytes / 3 pieces = 7 bytes.
JP 2005-319187 A JP-A-6-304300

However, the technique described in Patent Document 2 that can reduce the data amount among the conventional techniques described above compresses up to 7 bytes, but if it can further compress up to 6 bytes, it further creates a free space in the storage means. Can do.
The technique described in Patent Document 2 compresses the number of sub-frames of symbol number X having the same symbol number in each of the first, second, and third reels. For this reason, in order to obtain the number of sub-frames of symbol number X on the first reel, the number of sub-frames of symbol number X on other reels is expanded, and a wasteful calculation is performed.

  Furthermore, even if some reels have the same table, it is necessary to prepare the same table separately for each reel.

  In addition, the slip control includes control control in addition to the table control described above, and the control method can be varied for each reel, but the first reel is set as table control and the second reel and the third reel are controlled. When the technique described in Patent Document 2 is used in the case of control, there is a problem that in order to obtain the number of sliding frames on the first reel, the number of sliding frames on other reels that are not used at all must be developed. It was.

  The present invention has been considered in view of the above circumstances, and it is possible to compress the number of sliver frames up to 6 bytes, and to avoid useless operations such as compressing and expanding the number of unnecessary sliver frames, The object is to provide a data management method and a data management program.

  In order to achieve this object, the gaming machine of the present invention is a gaming machine that executes a control for shifting the reel by several frames so that the number of sliding frames is varied at the timing when the stop button is operated as a sliding control. Thus, the number of frames to be displaced when executing the slip control is set as the number of slide frames, and the number of 21 slide frames set in one reel is stored as the compressed number of slide frames expressed by 6 bytes in binary notation. The storage unit is provided.

When the gaming machine has such a configuration, the number of 21 smooth frames can be stored as 6-byte compressed frame number compressed data.
In the conventional technique, compression is possible up to 7 bytes, but a technique for compressing up to 6 bytes has not been proposed. This 1-byte difference is very large in a slot machine having a data area limit (within 3072 bytes), and becomes more significant as the number of sliding pattern tables increases.

Since the number of smooth frames is compressed and stored, the free space in the storage means can be increased, and various data and the smooth pattern table can be newly stored in this free space.
Furthermore, since the compressed data for the number of smooth frames is calculated for each reel, even if the compressed data for the number of smooth frames is expanded, the number of smooth frames set for other reels is not expanded. For this reason, it is possible to avoid a wasteful calculation such that the number of unnecessary smooth frames is expanded.
In addition, even if some reels have the same table, there is no need to prepare the same table separately for each reel.

In addition, the gaming machine of the present invention expresses the number of sub-frames from the first (symbol number 0) to the 20th (symbol number 19) out of 21 sub-frames by the 2-bit slip designating data, respectively. The number of sub-frames of (symbol number 20) is represented by binary-coded 4-bit sub-frame number data, and the sub-slip control performed by the number of sub-frames set regardless of the number of adjacent sub-frames is designated as a special sub-slip. The data for designating the number of smooth frames at the time of execution is designated as special smooth frame number designating data, and the smooth frame number compressed data can be constituted by combining these slip designating data, the smooth frame number data, and the special smooth frame number designating data.
If the gaming machine has such a configuration, the number of 21 smooth frames can be compressed to a data amount of 6 bytes.

In addition, the gaming machine of the present invention has stop designation data indicating that the slip designation data stops at the symbol, displacement designation data indicating displacement to another symbol, and a first special designation that designates one special slip. It can be configured to include four designation data of data and second special designation data for designating other special slip.
When the gaming machine has such a configuration, not only the normal number of sliding frames but also special sliding can be handled.

  In addition, the gaming machine of the present invention detects a symbol displayed on the winning line when the stop button is operated, and if this detected symbol is not a winning symbol for winning the gaming state won as a result of the internal lottery, a reel is inserted. If the symbol detected by shifting one frame is not the winning symbol, the process of shifting the reel by one frame is sequentially performed within the range of the maximum allowable number of frames, and the winning symbol is displayed on the winning line while the reel is shifted. And control to stop the reel at this time, and / or if the detected symbol is a winning symbol for winning a gaming state that is out of the result of the internal lottery, the reel is shifted by one frame, and the symbol detected after this shifting When is a winning symbol, the process of shifting the reel by one frame is sequentially performed within the range of the maximum allowable number of frames, and a predetermined symbol other than the winning symbol is a winning line while the reel is shifted. Is displayed, control control means for executing control for stopping the reel at this time as control control, and developing the smooth frame number compression data calculated by any one of claims 1 to 3, The table control means for performing the slip control and one or more reels including the reel corresponding to the stop button operated first are allowed to perform the slip control by the table control means, and for the other reels. Further, it is possible to provide a configuration including stop control means for performing slip control by the control control means.

When the gaming machine has such a configuration, among the plurality of reels, the reel corresponding to the first operated stop button (and the reel corresponding to the next operated stop button) is slipped by the table control means. Control can be performed, and for other reels, slip control can be performed by the control control means.
In this way, a variety of sliding controls can be realized in one gaming machine.

The data management method of the present invention is a data management method for storing the number of 21 smooth frames set in one reel as the number of compressed smooth frames, and the first to the 20th among the 21 number of smooth frames. The number of sub-frames up to is represented by 2-bit sub-frame designation data, the 21st sub-frame number is represented by sub-frame number data represented by 4 bits of binary numbers, and is related to the number of sub-frames set in adjacent symbols. The slip control performed by the set number of slide frames is designated as special slip, and the data specifying the number of slide frames when performing this special slide is designated as the number of special slide frames. The number of slide designation data, the number of slide frames and the number of special slide frames Combining with the specified data, the 6-byte compressed frame number compressed data is configured. There a method of storing the 憶 means.
Thus, the present invention can also be realized as a method.

The data management program of the present invention is a data management program for causing a data compression apparatus to execute processing for compressing the number of smooth frames set in one reel to obtain the compressed number of smooth frames. Of these, the number of the first to the 20th sub-frames is represented by 2-bit sub-frame designation data, and the 21st sub-frame number is represented by the sub-frame number data represented by 4 bits of binary numbers, which are set in adjacent symbols. The slip control performed by the set number of sliver frames regardless of the set number of sliver frames is designated as special sliver, and the data for designating the number of sliver frames when performing this special sliver is designated as special sliver frame number specification data. 6 bytes combining number data and special smooth frame number designation data It may be configured to execute the process of constructing the slip number compressed data to the data compression device.
Thus, the present invention can be realized as a program.

As described above, according to the present invention, it is possible to compress the number of smooth frames set in one reel to 6 bytes.
For this reason, since the free space increases in the storage means, it is possible to increase the sliding pattern table and to store more other data.

In addition, since the smooth frame number compressed data is independent for each winning combination and each reel, it is easy to handle and understand in the development process.
Furthermore, since the number of sliding frames is calculated for each reel, even when table control is performed for all of a plurality of reels, stop control of the first reel is performed by table control, and stop control of other reels is performed. Even when two control methods are mixed, such as when performing control control, it is possible to efficiently obtain the number of smooth frames without developing the number of unnecessary smooth frames.

[Control means]
Next, with reference to FIG. 3, the control means 40 for controlling the slot machine according to the present embodiment configured as described above will be described.
This figure is a block diagram showing an outline of the control means of the slot machine and its peripheral configuration according to the present embodiment.

The control means 40 of this embodiment is a control means for controlling each part of the slot machine 1 described above, and is configured to have a microcomputer including an IC, a memory, various circuit boards, and the like.
Specifically, as shown in FIG. 3, the control means 40 includes a CPU 41, RAMs 42 and ROM 43 as storage means, a clock generation circuit 44 for generating a reference clock, a random number generation circuit 45 for generating random numbers for internal lottery, A display unit drive circuit 46 that drives each of the display units 12a to 12d, a sound circuit 47 that generates sound from the speaker 19, a display unit drive circuit 48 that drives the display unit L for presentation, and the like are provided.

  The CPU 41 inputs the medal signal from the medal selector 16a and the medal signal from the insertion button 17 (17a, 17b), and the number of medals inserted from the medal insertion slot 16 and the medal betted by pressing the insertion button 17. The number of stored medals stored in the RAM 42 is decreased based on the medal signal from the insertion button 17. Thereby, the number of medals used (betting) for each game is determined.

  In addition, when the CPU 41 receives a start signal from the start lever 14, the CPU 41 outputs a pulse (drive) signal that serves as a control signal for the reels 21 a to 21 c to the drum unit 20. Thereby, in the drum unit 20, the reels 21a to 21c can be rotated by the start signal.

  Further, when receiving a stop signal from the stop buttons 15 a to 15 c, the CPU 41 outputs a pulse (drive) signal serving as a control signal for the reels 21 a to 21 c to the drum unit 20. Thereby, in the drum unit 20, the rotation of the corresponding reels 21a to 21c can be stopped by a stop signal input by pressing the stop buttons 15a to 15c.

  Then, when the rotation of the reels 21a to 21c stops, the CPU 41 recognizes the stop symbols of the reels 21a to 21c based on the marker signal input from the drum unit 20, and determines whether or not the stop symbols are in a predetermined winning arrangement. If the result of determination is a predetermined winning arrangement, a medal payout process corresponding to the type of winning is performed.

Further, as shown in FIG. 4, the CPU 41 has an internal lottery means 41-1, a data expansion means 41-2, a table control means 41-3, a control control means 41-4, and a stop control means 41-5. And have.
The internal lottery means 41-1 performs an internal lottery for each game and controls the game according to the result of the internal lottery.
The internal lottery is a lottery process performed for each game, and is executed by a lottery table that is preset and stored in the random number generation circuit 45 and the ROM 43 made up of a counter IC and the like, and the extracted random number is stored in any region of the lottery table The contents indicated by the area to which the user belongs are determined and won as a lottery result.
Specifically, the random number generation circuit 45 generates a random number within a predetermined random width range (for example, 1 to 16384). The lottery table is a data table stored in the ROM 43, and predetermined winning contents are assigned corresponding to a range (1 to 16384, etc.) that a random value can take.

The winning contents (game state) set in the lottery table include jackpots (special prizes such as BB, RB, etc.), small roles, replays, losers, etc., and the winning contents are within the range of random numbers. For example, 1 to 55: big win, 55 to 1055: small role, 1056 to 16384: lost, and so on, are assigned so that each content has a predetermined winning probability.
Then, at the moment when the start lever 14 is pressed, one random number is extracted from the random number generation circuit 45, and the extracted random number is collated with the value of the lottery table, so that the winning content to which the random number belongs is obtained as the lottery result. It is determined.

  The lottery result is sent to the table control means 41-3. Thereby, the stop positions of the reels 21a to 21c are controlled in accordance with the winning contents. That is, when a winning content is won, regardless of the timing at which the player presses the stop button 15, the symbols attached to the reels 21 a to 21 c are arranged according to the winning content within a certain range. Is controlled to stop (retraction control). In addition, when a certain winning content is off and the symbol displayed on the winning line is a symbol for winning the winning content, stop control is performed so that the symbol is removed from the winning line (kicking control). ).

  In the present embodiment, a gaming state in which the amount of gaming media to be paid out is relatively large, such as a big bonus or a regular bonus, is referred to as a “special accessory”. However, the specific combination is not limited to the big bonus and the regular bonus, and can include, for example, a challenge time, a single challenge time, a single bonus, and the like.

  The data expansion means (calculation means) 41-2 executes the expansion program, expands the smooth frame number compressed data, and calculates the number of smooth frames. A specific example of this decompression process will be described in detail later in “Compression process, decompression process (data management method)”.

The table control means 41-3 performs sliding control (table control) of the reel 21 using the sliding frame number table.
That is, when the table control means 41-3 receives the lottery result from the internal lottery means 41-1, the table control means 41-3 selects a smooth frame number table (sliver frame number compressed data) corresponding to the lottery result for three reels from the storage means. Take out. Next, a stop signal is received from the operated stop button 15, and the reel 21 corresponding to the operated stop button 15 is specified based on the stop signal. Subsequently, the smooth frame number compressed data for the identified reel 21 is selected and sent to the data expansion means 41-2. Furthermore, a marker signal is received from the winding position detection unit 24, and based on this marker signal, the pattern detected by the rotation position detection unit 24 (the pattern displayed on the winning line when the stop button 15 is operated) is displayed. Check. Then, the number of sliver frames corresponding to the detected symbol is selected from the number of sliver frames after the expansion process received from the data expansion unit 41-2, and a pulse (drive) signal indicating the selected number of sliver frames is sent to the motor drive circuit 22. Then, the slip control is performed so that the reel 21 is displaced by the number of the slip frames.

A specific example will be described.
For example, if the lottery result in the internal lottery means 41-1 is RB winning, the table control means 41-3 stores the smooth frame number table (sliver frame number compressed data) for RB for the three reels. (ROM 43). Next, when the stop button (left) 5a is operated, the table control means 41-3 specifies the corresponding reel (left) 21a. Subsequently, the data for the reel (left) 21a is selected from the smooth frame number compressed data already taken out from the storage means, and is sent to the data expansion means 41-2 for expansion processing.
Further, the table control means 41-3 confirms (detects) the number (for example, symbol number 18) of the detected symbol of the reel (left) 21a based on the marker signal from the rotating drum position detector 24, and confirms this. The number of smooth frames having the symbol number 18 is selected from the number of smooth frames after the expansion process (here, the number of smooth frames is “1”). A pulse (drive) signal indicating the selected number of smooth frames “1” is sent to the motor drive circuit 22 and is shifted (slid) by one frame during the stop control of the reel (left) 21a, and the symbol number 19 is displayed. The slip control is performed.

  The control control means 41-4 and the stop control means 41-5 will be described in detail in “Control Control” below.

The storage means (RAM 42, ROM 43) stores data relating to the game. Further, the storage means stores a development program (ROM 43). Further, the storage means stores various data (each data shown in FIGS. 8 to 13) calculated when the expansion program is executed.
The storage means stores a smooth frame number table. The number of smooth frames included in the number of smooth frames is stored as the number of compressed frames. Thus, by storing the number of smooth frames as compressed data, the free capacity of the storage means can be increased and other data and a larger number of smooth pattern tables can be stored.

Further, the storage means stores a plurality of smooth frame number tables for each reel 21. In addition, a plurality of smoothing frame number tables for the same gaming state per reel 21 can be stored. In this case, the table control means 41-3 performs a predetermined process and selects one smooth frame number table from the plurality of smooth frame number tables taken out from the storage means. This selected smooth frame number table is used when determining the number of smooth frames.
In this way, by storing a plurality of the number of smooth game number tables for the same gaming state for each reel 21, even if the same gaming state is won in the internal lottery and the same symbol is displayed when the stop button 15 is operated, table control is performed. The means 41-3 can select a different number of smoothomas for each game. For this reason, the slip control can be performed with the number of smooth frames that vary greatly for each game.

Here, the smooth frame number table will be described.
As shown in FIG. 13, the smooth frame number table is a table representing the number of smooth frames set for each reel 21 and each symbol. The number of smooth frames is set to any number from “0” to “4”.
The reason why the number of smooth frames is any one of “0” to “4” is as follows.
On the reel 21, 21 symbols are usually drawn. If the stop button is operated while the reel 21 is rotating, the reel 21 must be stopped within 190 msec from this operation. This stop within 190 msec is a stop within 0 to 4 frames in the design. Therefore, the number of smooth frames is any one of “0” to “4”.

Among them, the number of smooth frames is “0” indicates that the symbol displayed on the winning line is displayed as it is at the timing when the stop button is operated and is stopped (so-called bitter stop).
The number of smooth frames “1” to “4” indicates that the symbol located at a position displaced by the number of the smooth frames from the symbol displayed on the winning line at the timing when the stop button is operated is displayed to stop. .

In the sub-frame number table, if any of the adjacent symbols becomes a detected symbol and is controlled so as to be finally displaced to another symbol, “4”, The number of smooth frames is set in the order of “3”, “2”, and “1”.
For example, symbol numbers 18 to 15 correspond to the table shown in FIG. In these, the number of smooth frames is set in the order of “1” to “4”, and finally stops at symbol number 19.

Further, any one of “4”, “3”, “2”, and “1” can be set independently in some places regardless of the number of smooth frames of the front and rear symbols. Thereby, unexpectedness can be given to sliding.
For example, symbol numbers 12, 10, and 8 correspond to the table shown in FIG. In these, “1” or “4” is set regardless of the number of smooth frames of the preceding and following symbol numbers. This number of smooth frames is called the number of special smooth frames.

The configuration of the slot machine 1 according to the present embodiment described above is substantially the same as the configuration and functions of the existing slot machine except for the above-described units, and the game method, the game system, and the like are also substantially the same.
Therefore, detailed description of the same parts as those of the existing machine is omitted.

[Data compression device and data writing device (data compression writing system)]
Next, a data compression device for compressing the number of smooth frames and a data writing device for writing the compressed number of smooth frames in the ROM will be described with reference to FIG.
FIG. 1 is a block diagram showing a configuration of a data compression / write system including a data compression device and a data writing device.

As shown in the figure, the data compression apparatus 5 includes a storage unit 51, a data compression unit 52, a storage unit 53, an output unit 54, an input unit 55, a display unit 56, and a control unit 57. ing.
The storage unit 51 stores a compression program, a smooth frame number table, and other programs and data related to various functions of the data compression apparatus 5.
The data compression means 52 executes the compression program to compress the number of smooth frames to obtain the number of compressed smooth frames. A specific example of this compression processing will be described in detail later in “Compression processing, decompression processing (data management method)”.

The storage unit 53 stores the number of smooth frames (slide frame number compressed data) compressed by the data compression unit 52 in a portable recording medium 7 (for example, a flexible disk).
The output means 54 sends the number of smooth frames compressed by the data compression means 52 (sliver frame number compressed data) to the data writing device 6.
Note that the data compression apparatus 5 can include both the storage unit 53 and the output unit 54, or can include only one of them.

The input unit 55 includes a key and the like, and is a user interface operated by the user when performing compression processing.
The display means 56 displays predetermined items related to the compression process.
The control unit 57 reads a predetermined program from the storage unit 51 and operates related units in order to execute various functions of the data compression device 5.
Note that the data compression apparatus 5 can be configured by, for example, a personal computer.

The data writing device 6 includes reading means 61 for reading the compressed smooth frame number data from the recording medium 7 and writing means 62 for writing the read smooth frame number compressed data to the ROM 43.
However, the writing means 62 can also write the smooth frame number compressed data sent via the output means 54 of the data compression apparatus 5 to the ROM 43. In this case, the reading means 61 can be omitted.
The ROM 43 in which the smooth frame number compressed data is written by the data writing device 6 is mounted on the control means 40 of the slot machine 1.
The data writing device 6 can be constituted by, for example, a ROM writer.
In the present embodiment, the data compression device 5 and the data writing device 6 are collectively referred to as a data compression writing system A.

[Game operation]
Next, the gaming operation of the slot machine will be described with reference to FIG.
This figure is a flowchart showing an outline of the gaming operation of the slot machine according to the present embodiment.
Note that, as described above, the ROM 43 in which the smooth frame number compressed data is written is mounted on the control means 40 of the slot machine 1.

  First, a game is started when a player inserts a medal (game medium) into the medal slot 16 (step 10). Next, when the start lever 14 is pressed (operation of the spinning cylinder rotation start device, step 11), the three reels 21a to 21c start to rotate (step 12). A lottery is performed (step 13).

  Thereafter, when the player operates the stop buttons 15a to 15c (operation for stopping rotation of the spinning cylinder, step 14), the lottery result of the internal lottery is determined (winning a predetermined gaming state ?, step 15), and this lottery The reel rotation stop control is performed according to the result (slip control).

As a result of the determination, when a predetermined gaming state is won, slip control of the reel 21 is executed so that the winning gaming state wins (retraction control, step 16).
On the other hand, when the predetermined gaming state is not won, slip control is executed so that the gaming state does not win (kicking control, step 17).
Next, the rotation of the reels 21a to 21c is stopped, and it is determined whether or not the symbol (stop symbol) displayed on the winning line is a winning symbol (step 18). The number of medals corresponding to the number is paid out (step 19).
When a game is subsequently performed (step 20), steps 10 to 19 are executed.

[Compression processing, decompression processing (data management method)]
Next, compression processing and decompression processing of the number of smooth frames will be described with reference to FIGS.
FIG. 8 is a chart showing the correspondence between the number of smooth frames for symbol number 20 and the number of smooth frames, FIG. 9 is a chart showing the correspondence between the number of symbols for symbol number 19 to symbol number 0 and the slip designating data, and FIG. FIG. 11 is a chart showing the correspondence between the number of special sub-frames and the special sub-frame number designation data, and FIG. 11 is a chart showing the conversion process of each sub-frame number.

(Compression process)
First, the compression process of the number of smooth frames will be described.
(A1) Setting the number of smooth frames As shown in FIG. 13, usually 21 symbols are drawn on one reel, and the number of smooth frames is set for each symbol. There are five sub-frame numbers “0”, “1”, “2”, “3”, and “4”, and any one sub-frame number is set for each symbol.

(A2) Convert the number of sliver frames of symbol number 20 into 4-bit sliver frame number data.
This is to convert the number of smooth frames in decimal notation into the number of smooth frames in binary notation. The following smooth frame number data is obtained for each value of the smooth frame number.

Number of smooth frames Number of smooth frames “0” → “0000”
“1” → “0001”
“2” → “0010”
“3” → “0011”
“4” → “0100”

For example, since the number of smooth frames of the symbol number 20 shown in FIG. 13 is “1”, the number of smooth frames is “0001”.
As described above, the number of smooth frames having the symbol number 20 is represented by 4 bits.
A correspondence table between the number of smooth frames and the data of the number of smooth frames is illustrated in FIG.

(A3) The number of smooth frames from symbol numbers 19 to 0 is converted into 2-bit slip designating data.
Conversion to the sliding designation data is performed in order from the number of sliding frames of symbol number 19.
(A3-1) When the number of sliding frames is “0” The sliding designation data is set to “00”. This “00” is referred to as stop designation data.

(A3-2) When the number of smooth frames is a number obtained by adding 1 to the number of smooth frames of the previous symbol number The slip designating data is set to “01”.
For example, if the number of sub-frames for symbol number 18 is “1” and the number of sub-frames for the previous symbol number 19 is “0”, “1” is a number obtained by adding 1 to “0”. “01”. This “01” is referred to as displacement designation data.
On the other hand, when the number of sub-frames of symbol number 12 is “1” and the number of sub-frames of symbol number 13 of the previous time is “1”, “1” of symbol number 12 is the number obtained by adding 1 to “1” of symbol number 13 Therefore, the slip designating data is not set to “01”.
When the number of smooth frames is arranged in the order of “1”, “2”, “3”, “4” as in the case of symbol numbers 18 to 15, all of the slip designating data for the number of smooth frames is “ 01 ".

(A3-3) When the number of sliding frames is not the number obtained by adding 1 to the number of sliding frames of the previous symbol number The sliding designating data “10” (first special designating data) for designating special sliding A or special sliding B is used. It is converted into one of the designated slip designation data “11” (second special designation data).

Here, whether it is converted to “10” or “11” depends on whether the number of special smooth frames before conversion matches the number of special smooth frames of special smooth A or special smooth B.
For example, if the number of special sub-frames for special sub-A is 1 and the number of special sub-frames for special sub-B is four, the number of sub-frames for symbol number 12 is “1”. It is converted into slip designating data “10” designating A.
For symbol number 10, since the number of smooth frames is “4”, it is converted to slip designation data “11” that designates a special slip B that matches this number.

In addition, symbol numbers 12 and 10 are both numbers in which the number of smooth frames is not the number obtained by adding 1 to the number of smooth frames of the previous symbol number.
Further, a correspondence table between the number of sliding frames of symbol number 19 to symbol number 0 and the sliding designation data is illustrated in FIG.

(A4) Special slips A and B are defined.
As shown in FIG. 10, the number of special sub-frames can be originally set by selecting one of the four frames of one frame, two frames, three frames, and four frames. However, since the present invention aims to express the number of 21 smooth frames in 6 bytes, the number of frames that can be selected as the number of special smooth frames is limited. That is, in expressing the number of 21 sub-frames in 6 bytes (48 bits), the sub-frame number data of symbol number 20 is 4 bits, and the sub-designation data of symbol numbers 19 to 0 is 2 bits × 20 = 40 bits. Since each is expressed, the number of bits allocated to data for specifying the number of special sub-frames (special sub-frame number specifying data) is 4 bits.
Since the number of special sub-frames is four, “1” to “4”, it can be expressed by 2 bits. As a result, 4 bits / 2 bits = 2 types of special smooth frame numbers can be set.

Therefore, in this embodiment, two types of special slide A and special slide B are provided as special slides.
The special smooth frame number designation data of special slide A is set to “00”, and the special slide frame number designation data of special slide B is set to “11”. As a result, the number of special slide frames for special slide A is 1 frame, and the number of special slide frames for special slide B is 4 frames.

(A5) Generate the number of smooth frames compressed data.
The compressed smooth frame number data is generated by combining the smooth frame number data of symbol number 20, the slip designating data of symbol numbers 19 to 0, and the special smooth frame number designating data.
For example, the smooth frame number data, the slip designating data, and the special smooth frame number specifying data obtained by the methods (a1) to (a4) are arranged as follows.
`` 00 00 01 01 01 01 00 00 11 00 11 01 10 01 00 01 01 01 01 00 0001 00 11 ''

This smooth frame number compressed data is shown in FIG.
As shown in the figure, the compressed frame number compressed data consists of the specified bytes from the 1st byte to the 5th byte, the upper 4 bits of the 6th byte are the data of the number of live frames, and the lower 4 bits of the 6th byte are special. Each is composed of the number of smooth frame designation data and can be expressed by 6 bytes (48 bits).
By the above method, the number of 21 smooth frames set in one reel can be converted into 6-byte compressed data.

(Deployment process)
Next, the expansion process will be described. The decompression process is a process of decompressing the smooth frame number compressed data to obtain the smooth frame number.
(B1) The number of lower 4 bits (2 bits × 2) of the sixth byte of the sub frame number compression data is used as the special sub frame number designation data.
In this embodiment, “11”, which is the least significant 2 bits of the compressed subframe number data shown in FIG. 12, is designated as the special subframe number of special subframe B, and “00”, which is the next 2 bits, is the special subframe A. The number of special sub-frames is specified.

(B2) The upper 4 bits of the sixth byte of the smooth frame number compressed data are used as the number of symbols of symbol number 20 and are converted into the number of smooth frames.
For example, the upper 4 bits “0001” of the sixth byte of the compressed smooth frame number data shown in FIG. Then, “1” obtained by converting this binary number notation “0001” into a decimal number is the number of smooth frames of symbol number 20.

(B3) The upper 40 bits of the smooth frame number compressed data are used as the slip designating data from symbol number 19 to symbol number 0, and converted to the number of smooth frames for each symbol every two bits.
This conversion is performed by 2 bits from the lower order.
(B3-1) When the sliding designation data is “00” (stop designation data) The number of sliding frames is set to “0”.
(B3-2) When the slip designating data is “01” (displacement designating data) The number obtained by adding 1 to the number of the smooth symbols of the previous symbol number is set as the number of the smooth symbols of the current symbol number.
For example, if the designating data of symbol number 18 is “01” and the number of sub-frames of symbol number 19 of the previous time is “0”, the number “1” added to “0” by 1 is the number of sub-frames of symbol number 18. To do.
Similarly, when the designating data of symbol number 15 is “01” and the number of sub-frames of symbol number 16 of the previous time is “3”, the number “4” obtained by adding 1 to “3” is the number of sub-frames of symbol number 15. And

(B3-3) When the slide designation data is “10” (first special designation data) The number of special slide frames corresponding to the special slide frame number designation data of the special slide A is set as the number of slide frames of the symbol number.
For example, the slip designation data of symbol number 12 is “10”. For this reason, the number of special sliver frames “1” corresponding to the special sliver frame number designation data “00” of the special sliver A is the number of sliver frames of the symbol number 12.

(B3-4) When the slip designating data is “11” (second special designating data) The number of special sub-frames corresponding to the special sub-frame number designating data of special sub-B is set as the number of sub-frames of the symbol number.
For example, the slip designation data of symbol number 10 is “11”. For this reason, the number of special sliver frames “4” corresponding to the special sliver frame number designation data “11” of the special sliver B is the number of sliver frames of the symbol number 10.

(B4) The number of smooth frames obtained by (b1) to (b3) is the number of 21 smooth frames set for the reel.
Specifically, “0043210040421104432101” shown in FIG. 11 is obtained, and this is the number of smooth frames set in the first reel.

[Control control]
Next, control control will be described.
There are the following two types of control.
(1) A symbol displayed on the winning line when the stop button 15 is operated is detected, and it is determined whether or not the detected symbol is a winning symbol for winning the gaming state won as a result of the internal lottery. When the detected symbol is not a winning symbol, the reel 21 is shifted by one frame, and after the shifting, the symbol displayed on the winning line is detected, it is determined whether or not the detected symbol is a winning symbol, and the detected symbol is detected. When is not a winning symbol, the process of shifting the reel 21 by one frame is sequentially performed, and when the winning symbol is displayed on the winning line while the reel 21 is shifted within the range of the maximum allowable number of frames (normally five frames), The control to stop the reel 21.

(2) A symbol displayed on the winning line when the stop button 15 is operated is detected, and it is determined whether or not this detected symbol is a winning symbol for winning a gaming state that is out of the result of the internal lottery. When the detected symbol is the winning symbol, the reel 21 is shifted by one frame, and after the shifting, the symbol displayed on the winning line is detected, and it is determined whether or not the detected symbol is the winning symbol. When the detected symbol is the winning symbol, the process of shifting the reel 21 by one frame is sequentially performed, and a predetermined symbol other than the winning symbol is displayed on the winning line while the reel 21 is shifted within the range of the maximum allowable number of frames. Then, it means the control to stop the reel 21 at this point.
The control control (1) and (2) is performed by the control control means 41-4 of the CPU 41.

When one slot machine 1 is provided with both control control means 41-4 and table control means 41-3, one or two reels 21 corresponding to the first operated stop button are included. The reel control can be performed on the reels 21 by the table control means 41-3, and the slip control can be performed on the other reels 21 by the control control means 41-4. Thus, the process of assigning the slip control method for each reel is performed by the stop control means 41-5.
Thereby, various sliding controls can be performed by one slot machine 1.

As described above, according to the gaming machine, the data management method, and the data management program of this embodiment, the number of 21 smooth frames in one reel can be compressed to 6 bytes and stored. For this reason, since the storage means has a free space, it is possible to increase the sliding pattern table and store other data and programs.
Further, since the smooth frame number compressed data is calculated for each reel, it is possible to avoid a wasteful calculation in which an unnecessary number of smooth frames is expanded.

[Data management program]
Next, the data management program will be described.

As long as there is no special limitation.

  Furthermore, in the slot machine of the above-described embodiment, the case where the game medium to be used is a medal (coin) is shown, but the game medium that can be used in the slot machine according to the present invention is not limited to a medal, for example, a pachinko ball and Similar game balls can also be used as game media. A slot machine that can be played using such a game ball is also called a pachilot or the like, and can be applied as the slot machine of the present invention.

A game machine that executes a reel slip control so that a symbol corresponding to a lottery result stops or does not stop on a predetermined winning line based on the determined number of smooth frames. There,
The smooth frame number table is
The number of frames to be displaced when executing the slip control is defined as the number of slide frames, and the number of 21 slide frames corresponding to the 21 symbols of the reel set on one reel is expressed by 6 bytes in binary notation. Is stored in the storage means as the compressed number of smooth frames.
The smooth frame number compressed data is
Of the 21 smooth frame numbers, the first to 20th smooth frame numbers are represented by 2-bit smooth designation data in binary notation, respectively.
The 21st subframe number is represented by 4-bit subframe number data in binary notation,
Regardless of the number of sliding frames set for the adjacent symbol, the sliding control performed by the number of sliding frames set as a single frame number is designated as special sliding, and the number of sliding frames when performing this special sliding is a maximum of 4 in binary notation. Represented by the bit special sub-frame number specification data,
The slip designation data includes stop designation data indicating that the reel is stopped at the timing when the stop button is operated, displacement designation data indicating that the symbol is displaced from the symbol at the timing when the stop button is operated, And specially specified data,
The displacement designation data consists of data designating a number obtained by adding 1 to the number of smooth frames set in the symbol to be displayed next ,
The special designation data consists of data designating the number of sub-frames of the special sub-frame number designation data,
With these slip specified data, and it slipped number of data, the gaming machine characterized by being composed by arranging a special slide number specified data in a predetermined order. The gaming machine according to claim 1, wherein the special designation data includes first special designation data for designating one special slide and second special designation data for designating another special slide. When the stop button is operated, the symbol displayed on the winning line is detected, and if the detected symbol is not a winning symbol for winning the gaming state won as a result of the internal lottery, the reel is shifted by one frame and detected after this shift. If the winning symbol is not the winning symbol, the process of shifting the reel by one frame is sequentially performed within the range of the maximum allowable number of frames, and when the winning symbol is displayed on the winning line while the reel is shifted, Control to stop the reel with,
And,
When the detected symbol is a winning symbol for winning a gaming state that is out of the result of the internal lottery, the reel is shifted by one frame, and when the detected symbol after shifting is the winning symbol, the reel is shifted by one frame. The shifting process is sequentially performed within the range of the maximum allowable number of frames, and when a predetermined symbol other than the winning symbol is displayed on the winning line while the reel is shifted, the control to stop the reel at this point is controlled. Control control means to perform as
Table control means for developing the sliding frame number compressed data according to claim 1 or 2 and performing sliding control of the reel;
For one or two reels including the reel corresponding to the stop button operated first, slip control is performed by the table control means, and for other reels, slip control is performed by the control control means. The game machine according to claim 1, further comprising stop control means to be performed.
