In order to increase the amusement of the pachinko game, it is desirable to change the state of the movable piece arranged in the winning space in various ways. Since the movable piece that changes the state by being driven is separately arranged, there is a disadvantage that the configuration of the winning device becomes complicated, and the movable piece has a blade-like swinging piece or a rotating drum-like shape. However, the operation itself tended to be monotonous.

In addition, in Japanese Utility Model Laid-Open No. 61-4680, a rotating body having a ball receiving portion formed on the peripheral surface is rotatably mounted on the front side of a mounting board having a ball inlet, and a rotating body is mounted on the back side of the mounting board. A driving mechanism for rotating the ball, an entrance of a ball passage for giving a privilege is opened below the spherical inflow port, the rotating mechanism is rotated by the driving mechanism to remove the ball receiving portion from the spherical inflow port, and The lower end of the ball faces the entrance of the ball passage, and the hit ball does not enter the entrance of the ball flow entrance or the bonus ball passage with the privilege. Alternatively, the first state is difficult to enter, and the ball receiving section faces the ball inflow port, and the area around the entrance of the bonus ball path is opened to allow the hit ball to easily enter the ball inflow port or the entrance of the bonus ball path. A winning device of a pachinko machine that converts the state into a state is described.

The drive mechanism for rotating the rotating body in this winning device,
A rotating plate fixed to the tip of the rotating shaft of the rotating body, an elevating rod whose upper end is engaged with a pin of the rotating plate, and a ball mounting portion at the tip facing the first flow path and can be rotated halfway. And a link system composed of a swinging rod pivotally supported by the shaft. The operation of the link system is
First based on winning a special prize tool provided on the game board
This is performed by a pachinko ball that flows down the flow path, and the pachinko ball falls on the ball mounting portion of the swinging rod, pushes down one end of the swinging rod, and is pivotally attached to the other end of the swinging rod by swinging of the swinging rod. The lifting rod is raised, and the rotating plate is rotated by the raising and lowering of the lifting rod to rotate the rotating body by about 90 degrees, so that the hit ball is in a second state where it is easy to enter the ball inlet or the entrance of the bonus ball passage. Close.

Further, in this apparatus, a lock mechanism is provided for the rotating body to maintain the second state, and the electromagnetic solenoid is operated for the purpose of releasing the locked state by the lock mechanism. When the lock mechanism is unlocked, the link system operates in the opposite way to the above, and the rotating body does not enter the ball inlet or the entrance of the bonus ball passage from the second state. Difficult first
It is configured to return to the state.

Therefore, in this device, the operation of the drive mechanism for rotating the rotating body is directly performed by the pachinko ball,
Regardless of the pachinko ball, it is not configured to positively perform the rotation of the rotating body arbitrarily or when a specific condition is satisfied.

SUMMARY OF THE INVENTION An object of the present invention is to provide a highly entertaining new pachinko machine capable of solving the above-mentioned disadvantages of the prior art and positively changing the state of a movable piece with a simple configuration. A prize winning device is provided.

Means for Solving the Problems A winning device for a pachinko machine according to the present invention is a pachinko machine having a movable piece that can be changed between a first position that is advantageous to the player and a second position that is disadvantageous to the player. A winning device, wherein the movable piece is provided movably within a range between the first position and the second position, and the pachinko ball is passively changed from the first position to the second position by the weight of the pachinko ball. The movable piece is provided with a ball receiving portion for receiving the movable piece, and the movable piece is separately moved from the first position to the second position by the operation of the electromagnetic driving means.
A movable piece driving device for positively shifting to a position is provided.

In addition, there is a prize space that is contacted via the special winning opening,
The movable piece is arranged in the winning space.

Operation The pachinko ball that has won the big winning opening falls into the upper winning space on the near side.

The pachinko balls fitted into the cutouts on the movable one side are discharged from both sides of the upper winning space on the front side toward the downstream end of the bottom of the lower winning space, and after the discharge is completed, the movable piece is initialized by its own weight. It returns to the position and the opening of the partition is closed.

Also, when the pachinko ball falling into the upper winning space on the front side collides with the upper end of the movable piece, the movable piece is forcibly opened to the left and right due to the impact force and the weight of the pachinko ball, and the opening is momentarily opened. The pachinko ball may fall into this opening.

Pachinko balls discharged from the notch of the movable piece that opens left and right will win a special winning opening or a normal winning opening arranged at the downstream end of the bottom of the lower winning space, but the open position of the movable piece will be Since it is on both sides of the upper prize space, it is highly probable that the prize will normally be won.

In addition, since the opening of the partition is open when the movable piece is opened to the left and right, the probability that the pachinko ball winning the big winning opening falls on the bottom surface of the lower winning space through the opening of the partition increases. .

The pachinko ball that has fallen on the bottom of the lower prize space rolls to the downstream end along the slope of the bottom, but the probability of winning the special prize opening is because the opening of the partition wall is provided at the approximate center. Is high.

When the pachinko ball wins the special winning opening, the electromagnetic driving means operates, the movable piece driving device operates, and the movable piece is forcibly opened, so that continuous winning in the special winning opening is possible. .

After confirming that the right second-class start-up opening winning memory flag F2 is set, the CPU 50 starts the process of opening the blade 3 by exciting the large winning opening opening solenoid SOL.

When the middle type 2 opening mouth winning storage flag F1 is set, the CPU 50 resets the middle type 2 opening opening winning storage flag F1 and sets 2 to the repetition number setting counter C5 (step S306). When the left and right type 2 start opening winning memory flag F2 is set, the left and right type 2 opening opening winning memory flag F2 is reset and the setting counter C5 is repeated several times.
Is set to 1 (step S307), the index SIG defining the driving direction of the controlled object is set to -1, the big win opening flag F4 is set, and the timer T1 for the solenoid is set to time t5 to start. (Step S308).

The flag F4 has already been set in the "winning device driving process"
Is set, the CPU 50 proceeds to step S309 after executing the determination processing in step S302, and proceeds to step S309 to execute the timer for solenoid.
It is determined whether or not the set time of T1 has elapsed, and if the set time of the timer T1 has not elapsed, the “winning device driving process” of this cycle ends.

Step S301, step S302, step S30 for each cycle
When it is confirmed in step S309 that the set time (= t5) of the timer T1 has elapsed during the repetitive execution of the processing of step 9, the CPU 50 reverses the sign of the index SIG, and sets the time t4 to the timer T1 for the solenoid. Set and start (Step S3
10), it is determined whether the sign of the index SIG is positive or negative (step S31).
1) Since the value of the index SIG is (-1) ² = 1,
CPU50 excites the big win opening solenoid SOL
Is released (step S312). That is, the second type starting ports 5, 6,
If a pachinko ball wins in any of 7 above, t
When 5 seconds have elapsed, the blade 3 is opened (FIG. 9, FIG. 10).
See figure).

Thereafter, the processing of step S301, step S302, and step S309 is repeatedly executed for each cycle in the same manner as described above, and it is determined in step S3 that the set time (= t4) of the timer T1 has elapsed.
When confirmed in 09, the CPU 50 reverses the sign of the indicator SIG,
The timer t1 for the solenoid is set to time t4 and started (step S310) to determine whether the sign of the index SIG is positive or negative (step S311). At present, the value of the index SIG is (-1) ³
= −1, the CPU 50 sets the special winning opening opening solenoid S
Release the magnetic excitation of the OL and close the blade 3 (Step S31)
2). That is, after the first opening of the blade 3 is executed, t
When 4 seconds have elapsed, the blade 3 is closed (FIG. 9, FIG. 10).
See figure). Next, the CPU 50 sets the repetition number setting counter C5.
Is decremented (step S314), and it is determined whether or not the value of the counter C5 has become 0 (step S315). If the value of the counter C5 becomes 0 at this stage,
When the number of repetitions setting counter C5 is initially set to 1 by winning the right second-type starting openings 6 and 7, the special winning opening opening flag F4 is reset, and the opening operation of the blade 3 is completed (step). S316, see FIG. 9).

On the other hand, when 2 is initially set in the number-of-repetitions setting counter C5 due to winning in the middle type 2 starting port 5,
Since C5 = 1, the process of step S316 is not executed, and the processes of steps S301, S302, and S309 are repeatedly executed in the same manner as described above in the “winning device driving process” after the next cycle, and during this time, When it is confirmed in step S309 that the set time (= t4) of the timer T1 has elapsed, the CPU 50 executes the processing of steps S310 and S311 in the same manner as described above, but the value of the index SIG is currently (− 1) Since ⁴ = 1, the CPU 50 magnetically excites the special winning opening solenoid SOL to open the blade 3 (step S312). That is, when a pachinko ball wins in the middle type 2 starting port 5, the blade 3 is opened again at the point of time t4 seconds after the first closing of the blade 3 (see FIG. 10). Thereafter, the same processing is repeated, and when the set time (= t4) of the timer T1 has elapsed, the second opening of the blade 3 is completed (see FIG. 10), and the value of the counter C5 becomes 0.
(Step S315), the special winning opening flag F4 is reset (step S316).

When the pachinko ball that has entered the special winning opening 2 wins the special winning opening 28 while the special winning opening 2 is opened and closed in this way, the accessory continuous operation switch SW5 detects the entering of the pachinko ball, The corresponding latch of the switch detection circuit 51 is set. The CPU 50 reads the information of the switch detection circuit 51 in the switch S101 of the "winning ball detection processing", and
The ball is confirmed to have entered the ball 28 (switch S107), and the continuous operation number setting counter C2 is incremented (switch S108).

Step S305 in the “winning device driving device” of the same cycle
The CPU 50 detects that the value of the continuous operation number setting counter C2 has been set in the step 50, and starts processing relating to the continuous opening of the special winning opening 2. First, the index SI defining the driving direction of the controlled object
G is set to 1, the continuous release flag F3 and the continuous release pause flag F5 are set, and the repetition number setting counter C5 is set to 2
Are set, and the times t1 and t2 are set in the solenoid timer T1 and the motor timer T2 to start (step S317), and the drive motor M is rotated forward (step S31).
8). In this case, the forward rotation of the drive motor M is for returning the movable piece 34 to the initial position, similarly to the processing in step S002, and generally does not affect the substantial operation of the movable piece 34.

Since the continuous opening flag F3 and the continuous opening pause flag F5 have already been set in the “winning device driving process” in the next cycle, the CPU 50 executes the determination process in steps S301 and S319, and then sets the motor timer T2 set time (= It is determined whether or not t2) has elapsed (step S320). If the set time of the timer T2 has not elapsed, it is further determined whether or not the set time of the solenoid timer T1 (= t1) has elapsed. (Step S3
21) If none of the set times has elapsed, the “winning device driving process” of this cycle ends after the determination process of step S321 ends.

In the “winning device driving process” after the next period, the determination process of step S301, step S319, step S320, and step S321 is repeatedly executed in the same manner as described above, but the set time t2 <
First, at step S320, the motor timer T2
Of the set time is detected. Therefore, the CPU 50 inverts the sign of the index SIG that defines the driving direction of the control target (step S322), and determines whether the sign of the index SIG is positive or negative (step S323). At present, the value of the index SIG is (−1). ¹ = -1
Therefore, the CPU 50 stops the forward rotation of the drive motor M (step S324).

That is, the forward rotation of the drive motor M is executed for t2 seconds after the entry into the special winning opening 28 is confirmed, and the movable piece 34 returns to the initial position regardless of the previous state (FIG. 11). reference).

Next, the CPU 50 decrements the value of the repetition number setting counter C5 (step S325), and determines whether or not the value of the counter C5 is 0 (step S326).
Since the value of the counter C5 is 2-1 = 1, a time t3 is set in the motor timer T2 and started (step S3).
27).

Hereinafter, in the same manner as described above, every predetermined period, step S301,
The determination processing of steps S319, S320, and S321 is repeatedly performed. Since the set time t2 + t3 <t1, the elapse of the set time of the motor timer T2 is detected in step S320. Therefore, the CPU 50 inverts the sign of the index SIG that defines the driving direction of the control target (step S322), and determines whether the sign of the index SIG is positive or negative (step S323). At present, the value of the index SIG is (−1). ^{Since 2} = 1, CPU50
Drives the forward / reverse control circuit MS to rotate the motor M in reverse (step S328), sets the time t2 in the motor timer T2, and starts (step S329).

That is, after the drive motor M performs the forward rotation operation for returning the movable piece 34 to the initial position for t2 seconds and stops for t3 seconds,
The reverse drive is started (see FIG. 11). Accordingly, after the cam 42 is confirmed to have entered the special winning opening 28, t2
After the elapse of + t3 seconds, the rotation is started from the initial position as shown in FIG. 6 toward the state as shown in FIG. 7, but while the small diameter portion of the cam 42 is in sliding contact with the cam follower 44, The position of the cam follower 44 is not displaced.
Is not driven, the movable member 34 starts to spread after the time tx at which the large diameter portion of the cam 42 starts sliding contact with the cam follower 44, and further, at the stage when the time ty has elapsed,
The relationship between 42 and the cam follower 44 is as shown in FIG. 7, and the movable member 34 is completely dispersed (see FIG. 11). Note that tx + ty ≦ t2, and the reverse rotation of the drive motor M has just started at the current stage immediately after the completion of step S328.

Hereinafter, in the same manner as described above, every predetermined period, step S301,
The determination process of steps S319, S320, and S321 is repeatedly performed. Since the set time t1 <t2 + t3 + t2, the elapse of the set time of the solenoid timer T1 is detected in step S321. Therefore, the CPU 50 sets the time t4 in the solenoid timer T1 and starts the same, and also excites the big winning opening opening solenoid SOL to open the blade 3;
The first release in the continuous release operation is performed (step S330).

That is, the first opening of the wing 3 of the special winning opening 2 in the continuous opening operation is performed after the elapse of t1 seconds after the entry of the ball into the special winning opening 28 is confirmed (see FIG. 11). ).

Hereinafter, in the same manner as described above, every predetermined period, step S301,
The determination processing of steps S319, S320, and S321 is repeatedly executed. Since the set time t2 + t3 + t2 <t1 + t4, the elapse of the set time of the motor timer T2 is detected in step S320. Therefore, the CPU 50 reverses the sign of the index SIG defining the driving direction of the control target (step S322),
Although the sign of the index SIG is determined (step S323),
At present, the value of the index SIG is (-1) ³ = -1, so the CPU
50 stops the driving of the driving motor M (step S324),
The value of the repetition number setting counter C5 is decremented (step S325), and it is determined whether or not the value of the counter C5 is 0 (step S326).
Since -1 = 0, the inversion output from the forward / reverse control circuit MS is further stopped (step S331), the continuous open pause flag F5 is reset, and an index defining the drive direction of the control target is set.
The SIG is set to 1 and the repetition number setting counter C5 is set to 18 (step S332).

That is, after the drive motor M confirms that the ball has entered the special winning opening 28, the forward rotation operation is executed for t2 seconds for the return of the initial position of the movable piece 34 and stopped for t3 seconds, and then the forward and reverse rotation control circuit MS The reverse rotation of the cam 42 and the cam follower are performed as described above by the reverse rotation for t2 seconds.
The relationship with 44 is as shown in FIG.
34 will be forcibly opened (see Fig. 11).

In the next cycle of the "winning device driving process", since the continuous release pause flag F5 has already been reset, the CPU 50 proceeds to step S
After execution of the determination processing in step 301 and step S319, it is determined whether or not the set time (= t4) of the solenoid timer T1 has elapsed (step S333). If the time has not elapsed, the value of the open winning number storage counter C6 is reduced. It is determined whether or not the number has reached 10 (step S334). If not, the value of the counter C6 becomes 4
Is determined (step S335), and if the value of the counter C6 is not 4, it is determined whether or not the set time of the motor timer T2 has elapsed (step S336). The drive output to the motor M is stopped (Step S33)
7). At the present stage immediately after the processing after step S333, the set time of the motor timer T2 has already elapsed when the inversion of the drive motor M is stopped in the processing before the previous cycle and the movable member 34 is completely spread. Since the processing of setting and starting the timer T2 has not been executed in the subsequent processing, and the determination result of step S336 is necessarily true,
The process of stopping the drive output to the drive motor M is appropriately performed. However, the drive motor M is in a stopped state, and the process of step S337 has no substantial effect.

Therefore, as long as the determination results of step S333, step S334, and step S335 are false, in the “winning device driving process” after the next cycle, steps S301, step S319, step S333, step S334, step S335, and step S336 Only the determination process and the process of step S337 are repeatedly executed at predetermined intervals.

Step S333 is performed while such processing is repeatedly executed.
When it is confirmed that the set time (= t4) of the solenoid timer T1 has elapsed, the CPU 50 inverts the sign of the index SIG defining the drive direction of the control target, and
Set time t4 to 1 and start (step S33
8) The sign of the index SIG is determined to be positive or negative (step S33).
9) Since the value of the index SIG is (−1) ¹ = −1 at present, the CPU 50 releases the magnetic excitation of the large winning opening opening solenoid SOL, closes the blade 3, and sets the repetition number setting counter C5. Decrement and store that the first opening / closing operation in the continuous opening operation is completed (step S340), and
It is determined whether or not the value of C5 is 0, that is, whether or not the opening operation of the blade 3 has been performed 18 times (step S34).
1) Since the value of the counter C5 is 17 (= 18-1) at present, the "winning device driving process" of this cycle ends after the execution of the determination process in step S341.

Hereinafter, in the same manner as described above, every predetermined period, step S301,
Step S319, step S333, step S334, step S33
5, repeatedly execute the processing of step S336, step S3377,
At step S333, the set time of the solenoid timer T1 (= t
When it is confirmed that 4) has elapsed, the CPU 50 inverts the sign of the index SIG defining the driving direction of the control target, sets time t4 in the solenoid timer T1, and starts the timer (step S338). Although the sign of the sign of the SIG is determined (step S339), since the value of the index SIG is (−1) ² = 1, the CPU 50 magnetizes the large winning opening opening solenoid SOL to open the blade 3. (Step S343), it is determined whether or not the value of the repetition number setting counter C5 is 4 (= 18−14),
Whether the opening / closing operation of the blade 3 has already been performed 14 times before the opening operation of the blade 3 performed in the current cycle, that is, the opening operation of the blade 3 performed in the current cycle is the 15th opening operation Is determined (step S344). Since the value of the counter C5 is 17 at present, the “winning device driving process” of this cycle ends after executing the determination process of step S344.

Hereinafter, whether the value of the repetition number setting counter C5 becomes 0 or 4
Or the value of the open-time winning number storage counter C6 reaches 10 or 4 unless a phenomenon occurs.
U50 is, in the same manner as described above, for each predetermined cycle, step S301, step S319, step S333, step S334, step S335,
The processes in steps S336 and S3377 are repeatedly executed, and in step S333, the set time of the solenoid timer T1 (= t4)
Each time it is confirmed that the elapsed time has elapsed, the opening and closing operation of the special winning opening opening solenoid SOL is repeatedly executed as described above.

That is, the wings 3 of the special winning opening 2 are repeatedly opened and closed every t4 seconds after the first opening in the continuous opening operation is performed after a lapse of t1 seconds after the entry into the special winning opening 28 is confirmed. , A series of continuous opening operations is performed (the eleventh
See figure).

If it is confirmed in step S344 that the opening operation of the blade 3 has become the fifteenth time during the execution of the continuous opening operation of the blade 3 in this manner, the CPU 50 drives the drive motor M to rotate forward to rotate the cam. Start the initial position return of step 42 (step
(S345), the time t2 is set in the motor timer T2 and started (step S346).

That is, at the stage when the opening operation of the blade 3 becomes the fifteenth time, the drive motor M is driven to rotate forward, and the cam 42 is moved from the position shown in FIG. 7 to the initial position shown in FIG. To start rotating. Since the cam 42 has a smooth fall from the large-diameter portion to the small-diameter portion, unlike the case of the above-described spreading, there is no time flag in the swing operation of the cam follower 44, and the cam follower 44 moves to the initial position of the movable member 34. Will be immediately started. Then, when the time ty until the large diameter portion of the cam 42 separates from the cam follower 44 elapses, the movable member 34 is completely returned to the initial position, and the forcibly spread state is released (see FIG. 11). When the time tx + ty has elapsed, the cam 42 returns to the initial position shown in FIG. At this stage immediately after the completion of step S345, the direct rotation of the drive motor M has just started.

Then, the CPU 50 executes the determination processing of step S301, step S319, step S333, step S334, step S335, and step S336 in the same manner as described above, but the motor timer T2
Is reset, the process of step S337 is not executed until it is determined in the determination process of step S336 that the set time (= t2) of the motor timer T2 has elapsed.

In other words, the drive motor M that has been directly rotated at the stage when the opening operation of the blade 3 has become the fifteenth time is driven until the set time (= t2) of the motor timer T2 elapses (see FIG. 11). ). As described above, since t2 ≧ tx + ty, the cam 42
Will be completely returned to the initial position shown in FIG.

Step S341 during execution of the continuous opening operation of the blade 3
When the value of the counter C5 becomes 0 and it is confirmed that the opening operation of the blade 3 has been performed 18 times, the CPU 50 sets the continuous opening flag F3 to 0 and changes the value of the continuous operation number setting counter C2. Increments and a series of consecutive opening operations
The completion of the number of times is stored (step S342), and the “winning device driving process” of this cycle ends.

On the other hand, while the continuous opening operation of the blades 3 is performed, the "winning ball detection process" (see FIG. 16) is repeatedly executed at predetermined intervals, and the continuous opening flag F3 indicating the continuous opening operation of the blades 3 Is set, the number of pachinko balls that have won in the winning device 4 (within the special winning opening 2) during the series of continuous opening operations is sequentially accumulated in the open-time winning storage counter C6.

The value of the open-time winning number storage counter C6 is sequentially referred to in steps S334 and S335 of the "winning device driving process" executed at predetermined intervals, and the value of the counter C6 becomes 4 in the process of step S335. Is confirmed, CPU50
Even if the opening operation of the blade 3 is not the 15th operation, the drive motor M is driven to rotate forward to start the initial position return of the cam 42 (step S347), and the motor timer T2 is set to the time t2.
Is set and started (step S348).

That is, in the present embodiment, the stage in which the opening operation of the blade 3 in the series of continuous opening operations is the fifteenth time (see FIG. 11), or the special winning opening 2 during the series of continuous opening operations.
At the stage when the number of pachinko balls won in the game reached 4 (No. 12
The drive motor M is rotated directly, and the operation of returning the movable member 34 to the initial position is started. In any case, the drive stop processing of the motor M is executed by the processing of the steps S336 and S337.

Similarly, when it is confirmed that the value of the counter C6 has become 10 in the processing of step S334, the CPU 50 releases the magnetic excitation of the large winning opening opening solenoid SOL and closes the blade 3 (step S334).
349), 0 is set to the number-of-repetitions setting counter C5 (step S349), and the flow shifts to step S341. In this case, since the determination result of step S341 is necessarily true,
The continuous release flag F3 is forcibly reset, and the value of the continuous operation number setting counter C2 is forcibly decremented (step S342).

Therefore, even if the opening operation of the blades 3 is not performed 18 times, when the number of pachinko balls that have won in the special winning opening 2 during the series of continuous opening operations reaches 10, the series of continuous opening operations The operation is completed (see FIG. 12).

If a winning in the special winning opening 28 is detected during a series of continuous opening operations, the continuous opening flag F3 is set in step S110 of the "winning ball detection process" (see FIG. 16).
Is forcibly reset.
This is detected in step S301, and the CPU 50 stops the series of continuous opening operations, shifts to step S317 after executing the determination process from step S302 to step S305, and starts the series of continuous opening operations of the blade 3 once again. And is repeated in the same manner as described above (see FIG. 13).

When a series of continuous opening operations are completed by the 18 opening operations of the blades 3 or the winning of 10 shots into the special winning opening 2, and the continuous opening flag F3 is reset, in the “winning device driving process” in the next cycle and thereafter, The determination process from step S301 to step S305 is executed. If the value of the continuous operation number setting counter C2 is not 0, a series of continuous opening operations of the blade 3 are repeatedly executed in the same manner as described above. (However, in the embodiment, the maximum is limited to 9 times).

The operation of the winning device 4 has been described with reference to the processing of the CPU 50 and the timing chart showing the operation of each control target, but the operation of the winning device 4 is not limited to this.
The drive can be arbitrarily controlled by changing the set values of the timer and the counter and the program of the ROM 48.

Effect of the Invention According to the pachinko machine prize winning device of the present invention, if the pachinko ball enters the ball receiving portion provided on the movable piece, the movable piece is passively disadvantageous to the player due to the weight of the pachinko ball. While the position can be changed from the position to the second position which is advantageous to the player, when the movable piece driving device is operated by the operation of the electromagnetic driving means, the movable piece can be arbitrarily set or the first piece can be set when specific conditions are satisfied. Since it is also possible to positively shift from the position to the second position, it is possible to positively change the state of the movable piece and change the winning probability without complicating the configuration of the prize winning device itself. Amusement can be further increased.
