Abstract

<P>PROBLEM TO BE SOLVED: To prevent bias of display patterns. <P>SOLUTION: A controller 3 generates direction pattern identification information as a lottery result. A summing means 9 counts a sum per each type of direction pattern. A bias determining means 10 compares each counted sum per each direction pattern with a bias determining value 13 set for each direction pattern. The bias determining means 10 determines that there is no bias when even one of the counted sums exceeds the bias determining value 13 and it drives a selecting means 11. The selecting means 11 collates each sum determined by the summing means 9 with a priority corresponding table 12 and it selects direction pattern identification information with the highest priority. A history means stores the direction pattern identification information selected by the selecting means 11. A pattern display 4 displays a direction pattern corresponding to the selected direction pattern identification information. By this, bias of the direction patterns is prevented. <P>COPYRIGHT: (C)2004,JPO

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention plays a game advantageous to a player by matching symbols used in gaming machines such as pachinko machines and slot machines. The present invention relates to a symbol control device. FIG. 5 shows a symbol control apparatus disclosed in Japanese Patent Laid-Open No. 2000-167164. The control device 51 includes symbol correlation data 52 that defines the correlation between the background image and the reach image. In the symbol correlation data 52, for example, cherry blossoms, thunder, typhoons, and snow are set as background images, and spring /
When summer / autumn / winter is set, the numerical value is high if the relationship between the background image and the reach image is deep, and the numerical value is small if the relationship between the background image and the reach image is thin. In addition, the background image switching means 53 of the control device 51 switches the background image at the end of the big hit game or the number of times of symbol variation game set in the control device 51. As a result of the winning lottery, for example, if the jackpot is lottery, the control device 51 displays the current background image (in the state where the symbol display 4 starts the symbol variation game corresponding to the jackpot lottery result). The background image displayed in FIG. 5) is selected and a control image 51 selects a reach image that has a low correlation with the current background image. This prevents the display pattern from being biased by a symbol display device such as a confirmed symbol or a notice display. [0003] For example, if the background picture is “sakura”, the reach picture “spring” is selected, and if the background picture is “thunder”, the conventional example is “ If the reach picture “Summer” is selected and the background picture is “Typhoon”, then “Autumn”
The reach image is selected, and if the background image is “snow”, the reach image “winter” is selected. Unless it switches, the same reach image is repeated,
There was a problem that the bias of the fixed symbol occurred. [0004] Therefore, the present invention provides a symbol control device capable of preventing the display pattern from being biased by the symbol display device such as the effect pattern, the confirmed symbol, the notice display, and the effect time, and improving the playability appealing visually. To do. In the present invention, a lottery is performed and a symbol change is started after the symbol change is started, and then stopped, while the symbol change is stopped based on the lottery result. In the symbol control device of the gaming machine that creates a gaming state advantageous to the player when the confirmed symbol is matched with the symbol,
A lottery result in the stored history is provided by including a history means for storing the lottery result and a selection means for selecting a display pattern different from the lottery result when the history stored in the history means is biased. When the bias occurs, the display pattern displayed on the symbol display differs from the previous display pattern, so that the prevention of the bias of the display pattern can be improved, and the playability appealing to the eye can be improved. 1 to 4 show an embodiment, FIG. 1 schematically shows a symbol control apparatus, FIG. 2 shows a variation pattern table 5, and FIG. 3 shows a history table. 6 shows the priority correspondence table 12. The symbol control apparatus will be described with reference to FIG. The symbol control device includes a ball detector 2, a control device 3, and a symbol display 4. The ball detector 2 is an input device for the control device 3, detects a ball that has won a start winning component 1 provided on a game board that is a game subject, and outputs a ball detection signal to the control device 3. The symbol display 4 is an output device for the control device 3 and displays a symbol variation game accompanying the start winning. The control device 3 is attached to the back side of the game board or the back side of the gaming machine frame on which the game board is mounted, and the computer is a ROM.
The game process is repeatedly executed while using the RAM as a temporary storage component in the process according to the program stored in the program, and includes a variation pattern table 5, a history table 6, a writing means 7, a packet number counter 8, and a summing means 9. , Bias determination means 10, selection means 11, and priority correspondence table 12. The variation pattern table 5 and the priority correspondence table 12 are formed by a storage component such as a ROM, and the history table 6 is formed by a storage component such as a RAM. The history table 6 and the writing means 7 form a history means. As shown in step 101, the symbol control device generates effect pattern identification information as a lottery result obtained by the control device 3 executing a lottery process, and the summing means 9 counts the total number for each type of effect pattern. In the predetermined number of symbol variation games, the number of times each effect pattern appears is obtained, and the total number for each effect pattern counted by the bias determination means 10 is determined in the control device 3 for each effect pattern type. Compare with value 13. When all the counted numbers are equal to or less than the bias determination value 13, the bias determination means 10 determines that there is no bias, and the history means stores the drawn production pattern identification information as a history and the symbol display 4 draws the lottery. The effect pattern corresponding to the performed effect pattern identification information is displayed (see NO in step 102 and step 104). On the other hand, 1 out of the total number counted
If the bias determination value 13 is exceeded at any time, the bias determination means 10 determines that there is a bias and drives the selection means 11 (see YES in step 102).
Each of the obtained total numbers is collated with the priority correspondence table 12 set for each type of effect pattern to select the effect pattern identification information with the highest priority, and the history means selects the effect pattern selected by the selection means 11. The identification information is stored as a history and the design display 4 displays an effect pattern corresponding to the selected effect pattern identification information (see step 103 and step 104), thereby preventing the effect pattern from being biased. The variation pattern table 5 will be described with reference to FIG. In the variation pattern table 5, the effect pattern identification information and the effect time are individually set for each change pattern number. For example, the effect pattern identification information “A” and the effect time “10 seconds” are set to the variation pattern number “1”, and the effect pattern identification information “B” and the effect time “15 seconds” are set to the change pattern number “2”. Is set to the variation pattern number “3”, the effect pattern identification information “C” and the effect time “20 seconds” are set, and the effect pattern identification information “C” and the effect time “30” are set to the variation pattern number “4”. Second ”is set, production pattern identification information“ C ”and production time“ 40 seconds ”are set for the variation pattern number“ 5 ”, and production pattern identification information“ D ”and production time are set for the variation pattern number“ 6 ”. “20 seconds” is set, and the variation pattern number “7” has the effect pattern identification information “D”.
And the effect time “30 seconds” is set, the effect pattern identification information “D” and the effect time “40 seconds” are set in the variation pattern number “8”, and the effect pattern identification information “ E "and production time" 20 seconds "
Is set, the variation pattern number “10” is set to the effect pattern identification information “E” and the effect time “30 seconds”, and the variation pattern number “11” is set to the effect pattern identification information “E” and the effect time “40”. Second ”is set, production pattern identification information“ C ”and production time“ 45 seconds ”are set in the variation pattern number“ 12 ”, and production pattern identification information“ D ”and production time are set in the variation pattern number“ 13 ”. “45 seconds” is set, and the variation pattern number “14” includes production pattern identification information “E” and production time “45”.
Second "is set. The effect pattern, which is the effect pattern identification information “A”, stops after the symbol fluctuates, and produces a deviation other than the winning symbol. Production pattern identification information “B”, “C”, “D”, and “E” produce a reach called normal reach or special reach, and each of these production patterns has a different design, background image, or the like. Fluctuation pattern numbers “1” to “11” are effects for removal, and fluctuation pattern numbers “12” to “1”
“4” is an effect for jackpot. The history table 6 will be described with reference to FIG. The history table 6 stores one or more lottery results. Specifically, the history table 6 includes a plurality of packets, and one lottery result is stored in the packet by the writing unit 7. Each packet has a packet number and effect pattern identification information “C”,
An effect C flag, an effect D flag, and an effect E flag corresponding to “D” and “E” are provided. The writing means 7 rewrites the packet with the packet number counted by the packet number counter 8 as follows. That is, the writing means 7 is the selecting means 1
1 or the effect flag corresponding to the effect pattern identification information from the bias determination means 10 is set to significant, for example, “1”, and the effect flag corresponding to the effect pattern identification information not selected is insignificant, for example “0”. To "". The packet number counter 8 is incremented by 1 to the pointer value stored every time rewriting of the history table 6 by the writing means 7 is completed.
The packet number is counted up from an initial value (for example, 1) by storing the value, and if the pointer value exceeds the maximum value (for example, 300) of the packet number set in the control device 3, the pointer value is counted. To the initial value. The summing unit 9 individually counts the total values of the effect C flag, the effect D flag, and the effect E flag which are significant in the history table 6, and the total of the counted values is the effect C total value and the effect D total. The value and the production E total value are stored in the total column 14 of the history table 6. The bias determination means 10 exceeds the effect C determination value, the effect D determination value, and the effect E determination value in which the effect C total value, the effect D total value, and the effect E total value obtained by the summing means 9 are the bias determination value 13. It is determined whether or not. Bias determination means 10 is production C
The selection means 11 when at least one of the total value, the effect D total value, and the effect E total value exceeds the effect C determination value, the effect D determination value, and the effect E determination value (that is, when bias occurs).
Is transferred to the writing means 7 in the other cases (that is, when there is no bias). For example, the effect C determination value is “30”, the effect D determination value is “15”, and the effect E determination value is “3”, and is set in the bias determination value column 15 that is the ROM of the control device 3. The selecting means 11 selects the effect C total value, the effect D total value, and the effect E total value from the summing means 9 from the priority correspondence table 12 (FIG. 4).
The priority corresponding to the effect C total value, the effect D total value, and the effect E total value are individually extracted and stored from the priority correspondence table 12, and the highest priority among the extracted priorities. The effect pattern identification information of the priority is extracted and transferred to the writing means 7. As shown in FIG. 4, a priority correspondence table 16; 17; 1 corresponding to the priority correspondence table 12
8 is individually set for each of the production pattern identification information “C”, “D”, and “E”, and in the priority correspondence tables 16 to 18, each of the production C total value, the production D total value, and the production E total value decreases. Production C such that each priority becomes higher
A priority is individually set for each total value, effect D total value, and effect E total value. According to the structure of the embodiment, the power switch (not shown) in the pachinko machine is turned on, and the control device 3
In the activated state, a ball launched into the game area of the game board wins the start winning component 1, a start winning signal is input from the ball detector 2 to the control device 3, and the control device 3 inputs the start winning signal. Is detected, the control device 3 executes a lottery process. In the lottery process, the control device 3 acquires a random number value from the random number generation means at the winning timing of the start winning signal, collates the acquired random value with a lottery table stored in the control device 3,
From the lottery table, the fluctuation pattern number corresponding to the random value, the confirmed symbol identification information, and the notice identification information are extracted and stored as a lottery result. The control device 3 collates the obtained variation pattern number with the variation pattern table 5 in FIG. 2, extracts effect pattern identification information and effect time corresponding to the variation pattern number from the variation pattern table 5 and stores them. Then, the effect total value corresponding to the effect pattern identification information extracted by the control device 3 is transferred to the bias determination means 10. The bias determination means 10 determines whether or not the transferred effect total value exceeds the effect determination value (bias determination value 13) corresponding to the extracted effect pattern identification information, and the calculated total value exceeds the effect determination value. When it is determined that the display means is selected, the selection means 11 is driven, and in other cases, the effect pattern identification information transferred is transferred to the writing means 7. For example, when the control device 3 selects the variation pattern number “4” as the lottery result, the variation pattern identification information “C” is extracted from the variation pattern table 5 of FIG.
From the history table 6, since the effect C total value “31” of the variation pattern identification information “C” exceeds the effect C determination value “30”, it is determined that there is a bias, and the selection unit 11 is driven. The selection means 11 that has been driven by the bias judgment means 10 collates the effect C total value “31” with the priority correspondence table 16 shown in FIG. The priority “9” corresponding to the effect C total value “31” is extracted from the degree correspondence table 16 and stored, while the effect D total value “9” is shown in FIG. 4B for the effect pattern identification information “D”. Priority correspondence table 1 shown
7, the priority “13” corresponding to the effect D total value “9” is extracted from the priority correspondence table 17 and stored, while the effect E total value “1” is set to the effect pattern identification information “E”.
4 is compared with the priority correspondence table 18 shown in FIG. 4C, and the effect E total value “1” is compared with the priority correspondence table 18.
The priority “7” corresponding to is extracted and stored. The selection means 11 selects the effect pattern identification information “D” because the priority “13” of the effect pattern identification information “D” is the highest among the obtained priorities “9”, “13”, and “7”. And transferred to the writing means 7. The writing means 7 sets an effect D flag corresponding to the transferred effect pattern identification information “D” in the packet of the packet number “6” counted by the packet number counter 8 in the history table 6 of FIG. In addition to setting the effect C flag and the effect E flag to “0”, the rewriting of the history table 6 by the writing means 7 is completed. Then, the writing means 7 returns the transferred effect pattern identification information “D” to the control device 3. As the writing means 7 finishes rewriting the history table 6, the packet number counter 8 counts up the packet number, while the control device 3 displays the effect pattern identification information “D” returned from the writing means 7. 4 is output. Receiving the effect pattern identification information “D” from the control device 3, the symbol display 4 starts the symbol variation, and the effect pattern identification information “D” is transmitted via a reach where symbols other than the final stop symbol are hit. While performing the reach production which is the production pattern of No. 1, the final stop symbol is stopped according to the lottery result after performing the notice production that may be a big hit. When the confirmed symbols that have been stopped are matched with the winning symbols, the control device 3 controls the opening / closing drive source 19, and the opening / closing drive source 19 opens and closes the opening / closing body 21 of the variable winning component 20 provided on the game board to start the big hit game. To do. The total column 14 in the history table 6
If the production C total value of the production is less than or equal to “30”, the bias determination means 10 determines that the production C total value “30” is the production C judgment value “3”.
Since it is 0 or less, it is determined that there is no bias, the production pattern identification information “C” is transferred to the writing means 7, and the writing means 7 counts the packet number packet “ The effect C flag “6” is set to “1”, and the effect D flag and the effect E flag are set to “0”. It will be understood that the symbol display 4 displays the effect pattern of the effect pattern identification information “C”. In the above embodiment, the control device 3 is divided into a main control device and a symbol control device, the main control device is provided with a variation pattern table 5, and the symbol control device is a history table 6, a writing means 7, a packet number. A counter 8, a summing unit 9, a bias determination unit 10, a selection unit 11, and a priority correspondence table 12 are provided. The main control unit executes a lottery process and outputs production pattern identification information to the symbol control unit. The present invention can also be applied to a mode that operates in the same manner as the control device 3 of the above-described embodiment. According to this, the history table 6, the writing means 7, the packet number counter 8, the summing means 9, the bias determining means 10, the selecting means 11, and the priority correspondence table 12 can be omitted from the main control device. The storage capacity burden can be reduced. In the embodiment, the effect pattern is used as the display pattern. However, instead of the effect pattern, a confirmed symbol or a notice can be applied as the display pattern. When the lottery table is set so that the fixed symbols appear on the average, it is also possible to apply that the selecting unit 11 selects the smallest total symbol obtained by the total unit 9 instead of the priority. The reliability may be set for each of a plurality of types of notices, and the selection unit 11 may select a high reliability instead of the priority. An appearance value may be set in the notice, and when the notice does not appear even if the number of symbol variation games reaches the appearance value, the notice may be displayed in the next symbol variation game. It is also possible to change the production time. Replace the start winning signal with the game start signal,
If the symbol is stopped by inputting a symbol stop signal instead of stopping the symbol that has changed according to the program stored in the control device 3, the present invention can also be applied to a slot machine. In the above embodiment, when the lottery result is biased, a display pattern having a high priority is selected instead of the display pattern according to the lottery result. However, the history means stores a plurality of lottery results performed in the past. When all of the plurality of lottery results are the same, the bias determination means 10 determines that there is a bias, drives the selection means 11, and drives the selection means 11.
By selecting a display pattern that is different from the past lottery results, the bias can be eliminated. In this case, the history means stores the result of one lottery performed in the past, and this 1
If the result of lottery performed after the first lottery is the same as the result of one lottery performed in the past, the bias determination means 10 can be applied to determine that there is a bias. According to this, the priority correspondence table 12, the summing unit 9, and the packet number counter 8 can be omitted, and the capacity of the history table 6 can be minimized.
