Description

[0001]
BACKGROUND OF THE INVENTION
  The present inventionPachinko machineIn particular, to prevent fraud related to the jackpot game formPachinko machine capableAbout.
[0002]
[Prior art]
Conventionally, a pachinko machine has a jackpot lottery counter (= jackpot random number counter) that circulates while returning to the initial value again when the predetermined value is reached by adding 1 (= + 1) from the initial value and starting. It is made so that it becomes a big hit when the numerical value drawn at the timing when the ball is won in the mouth matches a predetermined specific numerical value (winning value).
[0003]
Since the jackpot lottery counter changes regularly at a constant cycle, once a jackpot is generated, the timing is repeated at a fixed cycle.
[0004]
Then, there are often a strategy method in which a ball is won at the start opening in accordance with the jackpot timing, or a “goto” act of operating the proximity switch of the start opening at this timing.
[0005]
On the other hand, every time the jackpot lottery counter makes a round, the initial value of the jackpot lottery counter is changed, and even if a winning signal is input at a fixed cycle timing of the jackpot lottery counter, the random value lottery lottery counter lottery is constant Measures are taken so as not to become.
[0006]
In this type of countermeasure, a random number counter for determining the initial value is provided, and this counter is updated one after another using the remaining time for each user reset, and when the big hit lottery counter makes a round, the next start of the big hit lottery counter is The jackpot random number update processing is performed so as to shift to the value of the initial value determination random number counter.
[0007]
[Problems to be solved by the invention]
In general, the remaining time for each user reset depends on the size of various processes performed by the gaming machine and varies according to changes in the state of the gaming machine. It is said that the initial value random numbers that can be used every time when the counter is counted up irregularly and the jackpot random number counter makes a round are scattered appropriately.
[0008]
However, in practice, the initial value random number that can be used every time the jackpot random number counter makes a round is obtained by sampling the random number sequence for initial value determination every round of the jackpot random number counter. Depending on how you proceed, there may be bias.
[0009]
When this point is abused and the goth actor modifies the gaming machine and performs predetermined intervention from the outside, it must be considered that the fluctuation of the remaining time is not necessarily guaranteed.
[0010]
If the remaining time for each user reset is continuously controlled by the goto action, the number of updates of the initial value determination random number counter for each reset is also controlled, so that a significant bias occurs in the value of the initial value determination random number counter. there's a possibility that.
[0011]
In such a situation, the initial value random numbers that can be used every time the jackpot random number counter makes a round are also biased, and there is a possibility that a small number of initial values in the same or a specific range may be repeated, which provides a clue to capture. When the remaining time is controlled, the total remaining time when the individual remaining time is kept constant over a certain period of time (unit maintenance of the state) or when a predetermined number of user resets are performed. Control that keeps constant (global maintenance of the state) becomes a problem.
[0012]
  Therefore, an object of the present invention is to monitor the remaining time that can be used for each user reset, and thereby to take measures against fraudulent acts against anticipated goto acts and further enhance security.Pachinko machineIs to provide.

[0032]
Next, FIG. 9 is a block diagram showing the electrical configuration of the present system, which is provided on the back side of the game board 1.
[0033]
Reference numeral 100 denotes a main board having a game control management function and a command command generation function, and is responsible for security control according to the present invention.
[0034]
The main board 100 is used as a CPU 101 that performs overall control, a ROM 102 that stores various control programs for executing security control according to the present invention, a storage area for various data, a work area for arithmetic processing, and the like. A RAM 103 or the like is attached. Reference numeral 102a denotes a module storage area.
[0035]

[0036]
A special symbol start switch 22, a normal symbol operation switch 23, and a big prize opening switch 24 are connected to the input side sub-board 20 via an input port 21. Further, a power supply circuit 25 and a reset circuit 26 for causing the main program to be reset at a predetermined cycle are provided.
[0037]

[0039]
(System operation)
Hereinafter, the operation of this system will be described with reference to FIGS.
[0040]
In this example, security processing by monitoring the remaining time at the user reset interval will be described.
[0041]
FIG. 1 shows a method of counting the number of times the remaining time reaches a certain time and comparing it with the maximum limit number as an algorithm of a control program for security (countermeasures against fraud).
[0042]
(Explanation of flowchart)
First, the overall processing flow of the flowchart of FIG. 1 will be described.
[0043]
The process performed within one user reset is divided into a normal process (step S1) and a process (steps S2 to S5) performed during the remaining time after the end of the normal process.
[0044]
Step S1 shows normal processing for executing processing in various gaming states.
[0045]
Here, the normal process will be briefly described. For example, in the game board 1 of FIG. 8, when the game ball 11 wins the start winning opening 2, the three symbols of the special symbol display device 3 start to change. When the display result is a combination of specific symbols (that is, a big hit), the variable winning ball apparatus 4 performs an opening operation. Further, when the game ball 11 wins the continuous winning area 6 in the variable winning ball apparatus 4, a new opening operation (continuous control processing) is performed after the completion of the opening operation.
[0046]
Further, when the game ball 11 passes through the normal symbol operation gate 8, the normal symbol display device 7 changes, and when the specific symbol is stopped and displayed on the display device 7, the electric tulip which is the normal electric accessory 2 Will be released.
[0047]
Step S1 includes most of the processes normally performed by the gaming machine as described above, for example, updating of the jackpot lottery counter, and various processes related to the normal symbols and special prize symbols.
[0048]
Steps S <b> 2 to S <b> 4 show various update processes performed in the remaining time after the process of step S <b> 1 ends.
[0049]
In step S2, the design random number is updated. In step S3, the security random number counter is used to add 1 to the numerical value of the security random number memory and overwrite the security random number memory using the remaining time of the user reset.
[0050]
However, in the above arithmetic processing, it is programmed to return to 0 again when the result of addition exceeds a certain value (for example, 255). As a result, the security random number counter always circulates in the range from 0 to the predetermined value, and is used in the security processing described later.
[0051]
In step S4, the initial value determination random number set as the initial value of the jackpot random number is updated.
[0052]
In step S5, a residual time counter (see FIG. 2 to be described later) is set immediately after the initial value random number update process performed within the remaining time of the user reset interval, and this residual counter is updated by updating the initial value determination random number. Immediately afterwards.
[0053]
In this way, since the number of updates of the remaining time counter varies depending on the length of the remaining time, the remaining time can be monitored by reading and checking the counter value at each user reset.
[0054]
It is assumed that the monitoring of the remaining time and the processing based on the result are incorporated as one subroutine in the normal processing in step S1.
[0055]
(Remaining time)
Next, the remaining time will be described.
[0056]
The user reset is performed using the reset circuit 26 of FIG. 9 described above, and an interrupt is generated at a constant cycle, and the processing of this control program is restarted from the top address at every interrupt timing. For example, the processing from step S1 to step S5 in FIG. 1 is periodically executed at intervals of 4 msec.
[0057]
The remaining time for each user reset depends on the size of various processes performed by the gaming device, and varies according to changes in the gaming state. For example, in the gaming state in which the normal symbol is activated and in the state in which the special prize symbol is started, the length of processing time in the normal processing in step S1 is different, and therefore, from step S2 to step S4 according to the change in the gaming state. The time required for this process, that is, the remaining time also changes.
[0058]
As a result, in the normal gaming state, the game ball irregularly activates the normal symbol or starts the special symbol, so the remaining time for each user reset also changes appropriately, and the initial value determination random number counter Since it is counted up irregularly, initial value random numbers that can be used for each round of the jackpot lottery counter are also scattered appropriately.
[0059]
On the other hand, in a specific gaming state corresponding to the goth action, in order to control the initial value determination random number counter, for example, some gothic intervention including a process for keeping the remaining time constant over a certain time Is considered to be performed.
[0060]
Therefore, by checking whether or not the remaining time is continuously constant, it is possible to determine whether the game is a normal game state in which normal symbols, special award symbols, etc. are properly mixed, or some unnatural behavior including the possibility of goto acts. You can know what the state is.
[0061]
(Remaining time monitoring / security)
Next, the remaining time monitoring process and the security process will be described with reference to FIGS.
[0062]
(Remaining time monitoring)
The remaining time monitoring process will be described with reference to FIGS.
[0063]
FIG. 2 shows the overall flow of the remaining time monitoring and security processing.
[0064]
Reference numeral 109 denotes a remaining time counter for measuring the remaining time (see step S5 in FIG. 1). Reference numeral 110 denotes a remaining time monitoring unit that monitors the remaining time. Reference numeral 200 denotes a security countermeasure set processing unit for preventing fraud. In the following, each part described in detail is configured as a hardware or software means in the main substrate 100 of FIG. 9 described above.
[0065]
FIG. 3 shows an internal configuration of the remaining time monitoring unit 110.
[0066]
The remaining time monitoring unit 110 stores a predetermined number as a reference for the remaining time counter value capturing unit 111, the previous value memory 112, the comparison unit A113, the coincidence counter 114, the comparison unit B116, and the comparison unit B116. And a memory 115.
[0067]
In FIG. 3, the remaining time counter value fetching unit 111 fetches the counter value of the remaining time counter 109, overwrites the counter value in a predetermined memory in the comparison unit A <b> 1 and the previous value memory 112, and then the remaining time counter 109. Clear 109.
[0068]
The previous value memory 112 includes at least two storage parts, and when the current value is written in one of the two values, the other value is set for comparison reference.
[0069]
The comparison unit A113 compares the counter value with the previous counter value.
[0070]
The match counter 114 adds 1 to the counter value of the match counter 114 when the comparison results in a match, and clears the counter value of the match counter 114 when there is a mismatch.
[0071]
The coincidence counter 114 sends the counter value to the comparison unit B116, compares it with a predetermined fixed number 115, and outputs the comparison result. A predetermined security measure is set according to the output result.
[0072]
FIG. 4 shows a method for monitoring the remaining time and a processing flow according to the result.
[0073]
In step S11, the value of the remaining time counter 109 is fetched.
[0074]
In step S12, the value of the previous remaining time counter 109 stored in the memory is referred to and compared with the current counter value.
[0075]
As a result of comparison, if they match, the process proceeds to step S13, and if they do not match, the process proceeds to step S14.
[0076]
In step S13, since it is determined that they match, the value of the match counter 114 is incremented by one.
[0077]
In step S14, since there is no match, the value of the match counter 114 is cleared.
[0078]
In addition, the determination of coincidence / non-coincidence may include not only the case where they are literally equal but also the case where one is different.
[0079]
When the remaining time of the user reset becomes constant, it can be detected by increasing the value of the coincidence counter 114.
[0080]
In step S15, it is determined whether or not the value of the coincidence counter 114 is larger than the K value. If the value is larger, the process proceeds to step S16.
[0081]
In step S16, it is determined whether or not the value of the coincidence counter 114 is greater than the KM value. When the value reaches a certain value or more, it is determined that the remaining time has become unnaturally constant, and security processing 1 ( Step S17) and security processing 2 (step S18) are performed.
[0082]
(Security processing)
5 to 7 show examples of security processing when the remaining time becomes constant. Each element shown in FIGS. 5 to 7 corresponds to a process using the ROM 102 and the RAM 103 in the main board 100.
[0083]
The security processing is executed in the above-described security countermeasure set processing unit 200 in FIG.
[0084]
As this security process, for example, a security process 1 (step S17 in FIG. 4) for generating an error sound and notifying the player, and a security process 2 (not noticed by the player) that does not generate an error sound (not shown in FIG. 4). Step S18).
[0085]
(Security processing 1)
An example of the security process 1 will be described.
[0086]
When a period that is constant according to the output value of the coincidence counter 114 reaches a predetermined value KM or more, an error sound is generated. Note that the error sound can be generated using a known technique.
[0087]
(Security processing 2)
An example of the security process 2 will be described with reference to FIGS. 5 to 7 show the processing contents in the security countermeasure set processing unit 200 of FIG.
[0088]
In this example, one of the three processes (see FIGS. 5 to 7) is performed according to the value of the security random number counter 203a. However, it is not always necessary to do so. Even if only one is performed, the same effect can be obtained.
[0089]
Here, when the value of the security random number counter 203a is different, prediction is difficult by performing completely different processing. In addition, since the remaining time at that time is affected by which of these processes is performed, there is an aim of making it difficult to control the remaining time.
[0090]
The security process 2 includes elements in each process shown in FIGS. 5 to 7, and performs any of the following processes (1) to (3) that differ depending on the remainder obtained by dividing the security random number by 3.
[0091]
(1) No remainder
The process A with no remainder will be described with reference to FIG.
[0092]
In FIG. 5, a predetermined change is given to the progress of the initial value determination random number counter 201. For example, the arithmetic unit 205 for adding the random value stored in the memory 203b of the security random number counter 203a to the random value stored in the memory 201b of the initial value determining random number counter 201a is performed, and the result is overwritten in the memory 201b again. Then, processing A for shifting the initial value determination random number counter 201a is performed.
[0093]
When the addition result exceeds the range of the initial value determination random number counter 201a in the calculation unit 205, the maximum value of the initial value determination random number counter 201a is subtracted from the addition result to determine the initial value determination random number counter 201a. The random number value stored in the memory 201b is set to fall within a predetermined range.
[0094]
(2) Remainder 1
The process B of the remainder 1 is demonstrated based on FIG.
[0095]
In FIG. 6, the arithmetic unit 207 adds the numerical value stored in the jackpot numerical memory 206 and the numerical value stored in the security random number memory 203b.
[0096]
The result of the addition is written in the jackpot value preparation memory 208 as a value corresponding to the jackpot, and processing B for overwriting the contents of the jackpot value preparation memory 208 to the jackpot value memory 206 at the timing when the jackpot lottery counter makes a round is set. Process C is canceled.
[0097]
As a result of the above addition, if the numerical value exceeds the range of the big hit lottery counter, the maximum value of the big hit lottery counter is subtracted from the added result so as to be within the range of the big hit lottery counter, and these are stored in the big hit number preparation memory 208 Write to.
[0098]
The big hit lottery counter here is provided in the main board 100 and has a function of counting +1 from the initial value every time the user is reset and circulating while returning to the initial value again when reaching a constant value of, for example, 300. Is. Then, when the numerical value drawn at the timing when the game ball 11 wins the winning prize opening 2 matches a specific numerical value (for example, a winning value = 7) set in advance in the big winning value memory 206, the big hit is made. Is set to
[0099]
(3) Remainder 2
The process C of the remainder 2 is demonstrated based on FIG.
[0100]
In FIG. 7, a numerical value table different from the currently used numerical value table 201 is selected from a plurality of big hit value numerical tables 201 stored in the ROM 102, and is selected (selected) from the ROM 102 at the timing when the big win lottery counter has made a round. The process C for calling the jackpot value table into the jackpot value memory 206 is set, and the process B is canceled (a plurality of jackpot value tables are stored in the ROM 102).
[0101]
If the value of the coincidence counter 114 exceeds K even once during the round of the jackpot random number lottery counter, one of the above is set. If the value of the coincidence counter 114 exceeds K several times during the round of the jackpot random number lottery counter, the last set contents are performed after one round except for the process (1). In either case, a warning signal may be output to the outside (such as a hall computer).
[0102]
As described above, the remaining time generated at each user reset is monitored using the remaining time counter 109, and if the remaining time becomes constant over a certain time, the security random number at that time By executing security processing that varies in various ways depending on the value, it is possible to make the capture by gotoing more difficult.
[0103]
In addition, if the remaining time becomes constant over a considerable period of time, it is difficult to continuously capture the same platform for a long time by making an error sound so that it can be heard by the player and its surroundings. This makes it possible to make it more difficult to capture by Goto.
[0104]
[Second example]
Next, a second embodiment of the present invention will be described with reference to FIGS. In addition, about the same part as the 1st example mentioned above, the description is abbreviate | omitted and the same code | symbol is attached | subjected.
[0105]
In this example, security processing by monitoring the sum of the remaining time in the user reset interval will be described.
[0106]
FIG. 10 shows the overall flow of the monitoring of the remaining time sum and the security processing. Reference numeral 300 denotes a remaining time sum monitoring unit that monitors the sum of remaining times.
[0107]
FIG. 11 shows an internal configuration of the remaining time sum monitoring unit 300.
[0108]
The remaining time sum monitoring unit 300 includes a remaining time counter value capturing unit 111, a remaining time counter value cumulative addition unit 310, an addition number counter 320, a first comparison unit 330, and a set number storage for storing a set number of times. The unit 340 includes a calculation unit 350, a second comparison unit 360, and a storage unit 370.
[0109]
FIG. 12 shows processing when the sum of the remaining times is constant.
[0110]
(Monitoring the sum of remaining time)
Hereinafter, a method for monitoring the sum of remaining times and a flow of processing according to the result will be described with reference to FIGS. 11 and 12.
[0111]
First, the remaining time counter value capturing unit 111 captures a counter value from the remaining time counter 109 (step S21).
[0112]
The counter value of the remaining time fetched from the remaining time counter value fetching unit 111 is sequentially accumulated and added to the remaining time counter value cumulative adding unit 310 (step S22).
[0113]
Each time the remaining time data is fetched, the counter value of the addition counter 320 is counted up.
[0114]
The first comparison unit 330 compares whether the counted-up counter value matches a preset number of times (step S23).
[0115]
In this case, if the set number of times is the maximum value of the jackpot lottery counter + 1, the remaining time can be cumulatively added over one round of the jackpot lottery counter.
[0116]
When the counter value of the addition counter 320 matches the set number, the cumulative addition value of the remaining time at that time and the set number are sent to the calculation unit 350.
[0117]
The calculation unit 350 obtains a remainder obtained by dividing the cumulative addition value by the set number of times (step S24).
[0118]
Here, the cumulative addition value of the remaining time counter value cumulative addition unit 310 and the value of the addition counter 320 are returned to 0 (clear) (step S25).
[0119]
Then, the remainder value obtained by the calculation unit 350 is sent to the second comparison unit 360.
[0120]
The second comparison unit 360 compares the remainder of this time with the previously obtained remainder and determines whether or not the difference (absolute value) of these remainders is smaller than a predetermined value (step S26).
[0121]
At this time, if the difference between the previous remainder and the current remainder is smaller than a predetermined value, the process proceeds to security processing (step S27).
[0122]
Note that if both the first comparison unit 330 and the second comparison unit 360 are negative, the security processing is not performed and the processing is directly terminated.
[0123]
(Security processing)
Here, as the security process, for example, one of the three security processes in the security process 2 (see FIGS. 5 to 7) in the case where the remaining time shown in the first example described above becomes constant is as follows. It may be executed at that time.
[0124]
As described above, even if the individual remaining time generated at each user reset is not constant, the security process is executed if the total value of the remaining time of the predetermined number of times has a certain regularity. Intervention in the remaining time can be made more difficult by action.
[0125]
[Third example]
Next, a third embodiment of the present invention will be described with reference to FIG. In addition, about the same part as each example mentioned above, the description is abbreviate | omitted and the same code | symbol is attached | subjected.
[0126]
In this example, the security process by directly monitoring the initial value of the jackpot lottery counter will be described.
[0127]
A monitoring means for monitoring whether or not the initial value random number that can be used every time the jackpot lottery counter makes a round, is continuously included in the same or predetermined range in the jackpot random number update processing that is normally performed, The monitoring means compares the initial value with the immediately preceding initial value, and checks whether the difference between the comparison results is within a predetermined range. If this difference falls within a predetermined range, it is determined that the initial value has continued to be a close value, and either security processing (1) or (2) described later is executed.
[0128]
In this example, since the initial value random number is directly monitored, monitoring of the remaining time is not necessarily required, and can be performed relatively easily. However, when a plurality of initial values are used alternately, it cannot be handled, and monitoring at the remaining time level is required.
[0129]
(Initial value random number monitoring)
Here, an initial value random number monitoring method used when the jackpot random number counter makes a round and a processing flow corresponding to the result will be described with reference to FIG.
[0130]
In step S31, the big hit lottery counter is incremented by one.
[0131]
In step S32, it is checked whether or not the value of the jackpot lottery counter exceeds the maximum random number.
[0132]
If it does not exceed the maximum value, the process proceeds to step S34. On the other hand, if it exceeds the maximum value, the process proceeds to step S33, and the jackpot lottery counter is set to zero.
[0133]
In step S34, whether or not the big hit lottery counter matches the initial value data is compared, and it is determined whether or not the big hit random number has made a round and returned to the initial value.
[0134]
If they match, the process proceeds to step S35 to extract an initial value determining random value. On the other hand, if they do not match, the process ends.
[0135]
In step S36, a difference between the extracted initial value determining random number value and the initial value data is obtained, and it is checked whether or not the difference is smaller than a predetermined value ε.
[0136]
When the difference is smaller than the value ε, in other words, when the initial value determination random number value continues to have the same value, the process proceeds to step S37, and security processing described later is executed.
[0137]
In step S38, the initial value determination random number value is stored in the jackpot random number.
[0138]
In step S39, the stored initial value determination random number value is stored in the jackpot initial value data. The initial value data is a value of 0 when the power is turned on.

【The invention's effect】
As described above, according to the present invention, the remaining time that fluctuates depending on the processing size of various game forms or the result of calculating the remaining time is continuously within a predetermined range. If it is within the predetermined range, it is considered that there is a possibility that some kind of goto action is being performed, and security processing is executed so that only a specific game form is not continuously performed As a result, it is possible to take countermeasures against fraudulent actions against anticipated goto acts and further enhance security.
[0143]
Further, according to the present invention, it is monitored whether or not the initial value random number used every time the big hit lottery counter makes a round, and only a specific game form is determined according to the monitoring result. Since the security processing is executed so as not to be performed continuously, it is possible to take measures against the anticipated goto action and further enhance the security.
