By viewing this, the operator of the playground can grasp the accurate sales of the crane game machine 100. Further, below the display of the income, the number of prizes whose payout is detected by the prize payout sensor 41 (the number of prizes paid out), the payout rate calculated as described later, and the winning probability of the current assist mode are shown. The assist mode occurrence probability shown is also displayed. In this way, the service monitor 401 functions as a consumption tax amount display means capable of displaying the consumption tax amount included in the income. The service monitor 401 also functions as a tax-excluded amount display means capable of displaying the tax-excluded amount obtained by subtracting the consumption tax amount from the income. In the present embodiment, both the consumption tax amount and the tax-excluded amount are displayed, but either one may be displayed, or both may not be displayed.

When the unit price, the payout rate, and the consumption tax rate of the free gift are set as described above, the CPU 300a executes an assist mode generated amount calculation process (step S109). In the assist mode generated amount calculation process, an amount (target amount) as a target for paying out a prize is calculated. That is, in this process, the amount of money required to pay out one prize is calculated as the amount of money generated in the assist mode, based on the unit price of the prize, the payout rate, and the consumption tax rate. Specifically, the assist mode generation amount (Ass) is calculated by the following equation (1). Here, (Pr) indicates the unit price of the prize, (PO) indicates the payout rate (%), and (t) indicates the value obtained by adding 100 to the consumption tax rate (%) set in the consumption tax rate setting process. .. In the present embodiment, the calculated amount of money generated in the assist mode is rounded up after the decimal point, but may be rounded down or rounded off. Further, when the payout in consideration of the consumption tax rate is not set, 100 is set in (t).
Ass=Pr×100/PO×t/100 (1)
For example, as shown in FIG. 6, when the unit price of the prize is set to 280 yen, the payout rate is set to 15%, and the consumption tax rate is set to 8%, the amount of money generated in the assist mode is 2016 yen. The amount of money generated in the assist mode thus calculated is stored in the RAM 300c. As described above, in the present embodiment, the control unit 300 functions as the target amount of money setting means.

The CPU 300a ends the payout setting process when the process for calculating the amount of money generated in the assist mode ends.

Next, a play process executed in the crane game machine 100 according to the present embodiment will be described with reference to FIGS. 7 and 8. Here, FIG. 7 is a flowchart illustrating the play processing, and FIG. 8 is a flowchart illustrating a continuation of the play processing illustrated in FIG. 7.

First, the CPU 300a determines whether a coin has been inserted (step S201). That is, the CPU 300a determines whether or not the input signals from the coin selectors 84a and 84b are input. When the CPU 300a does not determine that the coin has been inserted (step S201: No), the CPU 300a executes the process of step S201 until it is determined that the coin has been inserted.

On the other hand, when the CPU 300a determines that a coin has been inserted (step S201: Yes), it determines the denomination of the inserted coin (step S203). That is, the CPU 300a selects one of the denominations depending on whether the input input signal is the input signal from the coin selector 84a that receives a 100-yen coin or the input signal from the coin selector 84b that receives a 500-yen coin. Determine if there is.

Then, the CPU 300a determines whether or not the inserted coin is a 100-yen coin (step S205). When determining that the inserted coin is a 100-yen coin (step S205: Yes), the CPU 300a adds 100 yen to the income (I) indicating the total amount of the inserted coin (money) (step S207). .. The information on the income (I) is stored in the RAM 300c. On the other hand, when the CPU 300a does not determine that the inserted coin is a 100-yen coin, that is, when the inserted coin is a 500-yen coin (step S205: No), the income (I ) Is added with 500 yen (step S209). In the present embodiment, the income indicates the total amount of value used in the game.

After that, the CPU 300a calculates the tax-excluded amount and the consumption tax amount included in the income from the value of the income (I) stored in the RAM 300c (step S211). Specifically, the tax-excluded amount (Cn) is calculated by the following formula (2), and the consumption tax amount (Tx) is calculated by the following formula (3). Here, (t) represents a value obtained by adding 100 to the consumption tax rate (%) set in the consumption tax rate setting process (for example, if the consumption tax rate is 8%, “t=108”). ..
Cn=I×100/t (2)
Tx=I-Cn (3)
The tax-excluded amount and the consumption tax amount calculated as described above are displayed on the operation status display screen of the service monitor 401. As described above, in the present embodiment, the control unit 300 functions as a consumption tax amount identifying means. Further, in the present embodiment, the control unit 300 functions as a tax-excluded amount identifying means.

Subsequently, the CPU 300a determines whether or not it is the lottery mode based on the information of the dip switches 402a and 402b read at the time of activation (step S213). When the CPU 300a determines that it is in the lottery mode (step S213; Yes), it determines whether the cycle counter is 0 (step S215). The cycle counter is a counter that is set for each cycle of the number of plays set in the assist mode generation cycle initial setting process described above, and is decremented each time a game is played. When the cycle of the number of plays arrives, the cycle counter becomes 0. Is configured to be.

When the CPU 300a determines that the cycle counter is 0 (step S215; Yes), the CPU 300a executes the assist (A) mode generation cycle setting process (step S217) and then executes the process of step S219. On the other hand, when the CPU 300a does not determine that the cycle counter is 0 (step S215; No), the CPU 300a executes the processing of step S219 without executing the assist mode generation cycle setting processing.

Here, the assist (A) mode generation cycle setting process will be described with reference to FIG. Note that FIG. 9A is a flowchart illustrating the assist mode generation cycle setting process.

When the assist mode generation cycle setting process is started, the CPU 300a sets an initial value (play count initial value) to the cycle counter (step S301). The initial value set here is a value corresponding to the cycle of the number of plays set in the above-described assist mode generation cycle initial setting process. For example, the cycle of the set number of plays is "100". In this case, "100" is set as the initial value.

Subsequently, the CPU 300a calculates the carryover amount (step S303). The carry-over amount was obtained by multiplying the amount of money generated in the assist mode by the value of the paid-out prize counter (that is, the number of prizes paid out in the previous cycle) from the previous calculated value calculated as described later. Calculated by deducting the amount. As described above, in the present embodiment, the control unit 300 functions as a carryover amount identifying means.

After that, the CPU 300a adds the calculated carryover amount to the payout (P/O) converged amount initial value to obtain a calculated value (step S305). Specifically, the CPU 300a refers to the assist mode generation cycle setting table shown in FIG. 9B stored in the ROM 300b, reads out the amount of money corresponding to the play count initial value set in step S301, and sets it to P /O convergence amount initial value, and the carry-over amount calculated in step S303 is added to this to obtain a calculated value. In this embodiment, by setting the calculated value in this way, a more stable payout rate can be achieved. The initial value of the P/O convergence amount in the assist mode generation cycle setting table shown in FIG. 9B is set when the amount required to play one game is 100 yen, The P/O convergence amount initial value is set according to the amount of money required to play one game. For example, when one game is set to 200 yen, the P/O convergence amount initial value corresponding to the play count initial value “100” is “¥20,000”.

Subsequently, the CPU 300a calculates the payable counter added value by dividing the calculated value calculated in step S305 by the amount of money generated in the assist mode (step S307). That is, the CPU 300a obtains the number of times of performing the operation of the grip device 200 in the assist mode in this cycle. For example, when “¥10000” is set as the calculated value and the amount of money generated in the assist mode is “¥2016”, the calculated payable counter addition value is “4”. The CPU 300a sets the payout possible counter addition value thus calculated to the payout possible counter (step S309). As described above, in this embodiment, the control unit 300 functions as a winning number setting means.

After that, the CPU 300a clears the value of the paid-out prize counter (step S311), and then ends this processing.

Returning to FIG. 7, the CPU 300a sets the assist mode occurrence probability in step S219 (step S219). The probability of occurrence of the assist mode is obtained by "payout counter value/cycle counter value". Therefore, as the prizes are not paid out, the assist mode is more likely to occur as the number of plays is increased, and when the prizes are paid out, the assist mode is less likely to occur.

The CPU 300a executes a lottery process for performing a lottery on whether or not to generate the assist mode with the set probability of generating the assist mode (step S221).

The CPU 300a determines whether or not the generation of the assist mode has been won (step S223). If the CPU 300a has won to generate the assist mode (step S223; Yes), it sets the assist mode (step S225), and if it has not won to generate the assist mode (step S223; No), the normal mode is set (step S227). As described above, in the present embodiment, it can be said that the control unit 300 that executes step S223 functions as a hit/miss determination unit. Here, since the cycle counter value is decremented each time a game is played, it can be said that the amount (usage amount) corresponding to the value used for the game can be specified. Therefore, in the present embodiment, the control unit 300 can be said to function as a payout determination unit that makes a payout determination based on the unit price of the prize, the target payout rate and the consumption tax rate, and the usage amount.

The assist mode is a mode in which the operation of the gripping device 200 is controlled at a game difficulty level at which a prize is likely to be obtained. Specifically, as shown in FIG. The arm 203 is opened (that is, arm power with strength 0) (a), and immediately after the prize P is gripped and lifted, the arm 203 is closed with arm power of strength 7 and the prize P is gripped. (B). The arm power strength has a minimum value of 0 and a maximum value of 10, and the weight of the prize P in the present embodiment can be gripped and lifted when the arm strength is about 6 or more. After that, even in the process of hoisting the prize P, the arm power is kept constant (c) (d) (e). Therefore, in the assist mode, since the prize P can be relatively easily lifted while being supported by the gripping force of the arm 203, the prize P can be easily obtained. In this way, it can be said that the assist mode is a mode in which the prize acquisition easy control is performed.

On the other hand, the normal mode is a mode in which the operation of the gripping device 200 is controlled at a game difficulty level at which a prize is likely to be taken, and specifically, the gripping device 200 is lowered as shown in FIG. At the stage of making the arm 203, the arm 203 is brought into an open state (that is, arm power with strength 0) (a). Immediately after the prize P is gripped and lifted, the arm 203 is closed with the arm power of strength 8 to grip the prize P (b). After that, in the process of hoisting the prize P, the arm power is gradually weakened (for example, in (c) of FIG. 10(A), the arm power is reduced to 6 to grip the prize P, and (d)). Then, the arm power is further reduced to 4 and the prize P is gripped. As shown in (d) of FIG. 10(A), with arm power of strength 4, the force for gripping the prize P becomes insufficient, and the weight of the prize P causes the arm mounting portion 202 to start moving downward. Therefore, the arm 203 slightly moves in the direction in which the arm 203 is opened. After that, when the arm power is reduced to strength 3 at the stage where the gripping device 200 is fully raised, the prize P cannot be completely supported, and the prize P falls into the play field 2 (e). Thus, it can be said that the normal mode is a mode in which the prize acquisition difficulty control is performed.

As described above, the CPU 300a sets the mode to the assist mode or the normal mode and then executes the game process (step S229). In the play process, a process of accepting the operation of the operation lever 81 and the operation button 82 of the operation unit 8 and performing the moving operation and the gripping operation of the gripping device 200 within a predetermined time limit (for example, 30 seconds) is executed. .. At this time, the gripping operation of the gripping device 200 is controlled so that an operation according to the set mode is performed. As described above, in this embodiment, the control unit 300 functions as a drive control unit.

After that, the CPU 300a determines whether or not the prize has been paid out (step S231). Specifically, the CPU 300a determines the payout of the prize based on the presence/absence of a signal from the prize payout sensor 41.

When the CPU 300a determines that the prize has been paid out (step S231; Yes), it increments the prize payout counter, decrements the payable counter, and increments the paid-out prize counter (step S233). The value of the premium payout counter is used to calculate the payout rate. On the other hand, when the CPU 300a does not determine that the prize has been paid out (step S231; No), the CPU 300a executes the process of step S235 without performing the process of step S233.

After that, the CPU 300a decrements the cycle counter (step S235) and then calculates the payout rate (P/O) (step S237). The payout rate (P/O) is calculated by dividing the amount (payout amount) obtained by multiplying the set unit price of the prize by the value of the prize payout counter by the tax-excluded amount (Cn) of the income (I). The calculated payout rate is displayed on the operation status display screen of the service monitor 401.

After that, the CPU 300a determines whether or not there is a credit remaining (step S239). CPU300a performs the process of step S215, when it determines with credit remaining (step S239; Yes), and when it does not determine with credit remaining (step S239; No), ends the play process. ..

When the CPU 300a does not determine in step S213 that it is the lottery mode, that is, when it determines that it is the ceiling mode (step S213; No), it executes the process of step S241 in FIG. "100 yen" is added to the reserve amount as the amount (step S241). The accumulated amount of money to be added is set to the amount necessary for playing one game. For example, if the amount of accumulated money is set to 200 yen for one game, the accumulated amount of money to be added is set to "200 yen". ..

The CPU 300a determines whether or not the accumulated amount of money is equal to or more than the amount of money generated in the assist mode (step S245). That is, the CPU 300a determines whether or not the reserve amount has reached the ceiling amount.

When the CPU 300a determines that the accumulated amount of money is equal to or more than the amount of generated assist mode (step S245; Yes), the CPU 300a sets the assist mode (step S247), and does not determine that the accumulated amount of money is equal to or larger than the amount of generated assist mode. In this case, that is, when it is determined that the reserve amount is less than the assist mode generation amount (step S245; No), the normal mode is set (step S249). As described above, in the present embodiment, the control unit 300 including the CPU 300a that executes step S245 functions as a payout determination unit.

After setting the mode to the assist mode or the normal mode as described above, the CPU 300a then executes the game process (step S251). At this time, the gripping operation of the gripping device 200 is controlled so that an operation according to the set mode is performed.

After that, the CPU 300a determines whether or not the prize has been paid out (step S253).

When determining that the prize has been paid out (step S253; Yes), the CPU 300a increments the prize payout counter (step S255), and then sets the amount obtained by subtracting the amount of money generated in the assist mode from the accumulated amount to the accumulated amount. Then (step S257), the process of step S259 is executed. On the other hand, when the CPU 300a does not determine that the prize has been paid out (step S253; No), the CPU 300a executes the process of step S259 without executing the processes of step S255 and step S257.

After that, the CPU 300a calculates the payout rate (P/O) (step S259), and then determines whether or not there is a credit remaining (step S261). The CPU 300a executes the process of step S241 when it is determined that there is credit remaining (step S261; Yes), and ends the play process when it is not determined that there is credit remaining (step S261; No). ..

Next, another embodiment of the play process will be described with reference to FIG. FIG. 11 is a flowchart showing a continuation of the play process shown in FIG.

In this embodiment, if the lottery mode is not determined in step S213 of FIG. 7 (step S213; No), the process of step S271 of FIG. 11 is executed to calculate the payout amount (step S271). The payout amount is calculated by multiplying the unit price of the premium set in the premium unit price setting process by the value of the premium payout counter.

Thereafter, the CPU 300a calculates the payout rate (P/O) based on the income tax-excluded amount (Cn) and the payout amount (step S273), and the calculated payout rate (P/O) is set as the payout rate setting process. It is determined whether it is smaller than the set payout rate set in step S275 (step S275).

When the CPU 300a determines that the payout rate is smaller than the set payout rate (step S275; Yes), the assist mode is set (step S277), and when it is not determined that the payout rate is smaller than the set payout rate. (Step S275; No), the normal mode is set (step S279). Thus, in this embodiment, it can be said that the control unit 300 including the CPU 300a that executes step S275 functions as a payout determination unit.

After setting the mode to the assist mode or the normal mode as described above, the CPU 300a then executes the game process (step S281). At this time, the gripping operation of the gripping device 200 is controlled so that an operation according to the set mode is performed.

After that, the CPU 300a determines whether or not the prize has been paid out (step S283).

When determining that the prize has been paid out (step S283; Yes), the CPU 300a increments the prize payout counter (step S285), and then executes the process of step S287. On the other hand, when the CPU 300a does not determine that the prize has been paid out (step S283; No), the CPU 300a executes the process of step S287 without executing the process of step S285.

After that, the CPU 300a, after calculating the payout rate (P/O) (step S287), determines whether or not there is a credit remaining (step S289). The CPU 300a executes the process of step S271 when it is determined that there is credit remaining (step S289; Yes), and ends the play process when it is not determined that there is credit remaining (step S289; No). ..
