However, basically, in the spiral passage 60a from the ball exit 50b or 50c or 50d set so as to suggest the result of the above jackpot lottery, the result of the probability variation lottery, the result of the round number lottery, or the number of auxiliary games. It is assumed that priority is given to the control performed to discharge the production ball DB.

  Next, processing executed by the main control 21 will be described, and then processing control executed by the sub-control device 25 and effects produced by the ball guidance device 16 will be described.

  In the main control 21, in the big hit lottery, when the game ball B wins the start winning opening 10a, 10b and the start opening SW10d is turned on, the big hit random number is extracted when the number of reserved special symbols is not the maximum, When the big hit random number is a specific value, it becomes a big hit, and when the big hit random number is other than the specific value, it is lost. For example, the winning probability of the big hit lottery is either a low probability (for example, 1/300) or a high probability (for example, 30/1) depending on the gaming state.

  Next, as a special symbol, if the game is lost, the lost symbol is selected, and if it is a big hit, the big hit symbol is selected from the big hit symbol random numbers extracted together with the big hit random number. It is alternatively selected from a predetermined selection rate. The selected special symbol is displayed on the special symbol display 18a after the variable display.

  As shown in FIG. 12, for example, there are 14 types of jackpot symbols A to N, and for each jackpot symbol, the winning probability, the number of rounds, and the number of auxiliary games are determined as shown in the figure. The jackpot symbol is selected by lottery. The winning probability is the probability of a jackpot lottery after the jackpot game, and is either a low probability or a high probability. The number of rounds is the number of rounds in which the big prize opening 12a is opened for a predetermined time (for example, 1 second) during the big hit game, and is either 8R or 16R.

  The number of auxiliary games is the number of auxiliary games to be performed after the big hit game, and is defined by the number of special symbols, that is, the number of big hit lotteries, which is 0 times, 50 times, 100 times, and 10,000 times. It is either. In the auxiliary game, as compared with the normal game, the winning probability of the winning lottery performed when the game ball B passes through the gate 11 is increased, and the variation time of the normal symbol displayed on the normal symbol display 18b is shortened. At least one of the opening time of the start winning opening 10b is lengthened.

  That is, by selecting the big hit symbol by lottery, the probability variation lottery, the round number lottery, and the auxiliary game number lottery are performed. Then, the information on the selected special symbol is transmitted from the main control device 21 to the sub-control device 25, and in the special symbol information, the result of the big hit lottery, the result of the probability variation lottery, the result of the round number lottery, the auxiliary Includes the results of the number of game draws.

  As shown in the flowchart of FIG. 13, in the process control executed by the sub-control device 25, first, it is determined whether or not a change start command has been received (S1), and if S1; The variation start command includes information on the variation pattern, special symbol, and gaming state. When the variation start command is received (S1; Yes), the variation start command is analyzed (S2), and the variation pattern, You can get information on special symbols and gaming status, you can get the results of the jackpot lottery from the information of the special symbols, and if you win in the jackpot lottery, the result of the probability variation lottery, the result of the lot number lottery, The result of the auxiliary game frequency lottery can be obtained.

  Next, based on the result of the big hit lottery, the result of the probability variation lottery, the result of the round number lottery, the result of the auxiliary game number lottery, etc., whether or not to execute the effect ball guidance effect is selected by, for example, lottery (S3). If not executed (S4; No), the process returns. When executing (S4; Yes), when the execution start timing comes (S5), the effect ball guidance effect process control is executed (S6), and then the process returns.

  Here, the effect ball guidance effect processing control for suggesting the result of the big hit lottery is executed during the variation of the special symbol based on the big hit lottery, and the effect ball guidance effect processing control for suggesting the result of the probability random lottery, The effect ball guidance effect processing control for suggesting the result of the lot number lottery and the effect ball guidance effect processing control for suggesting the result of the auxiliary game frequency lottery are after the suspension of the special symbol based on the jackpot lottery. It is executed during a big hit game.

  As shown in the flowchart in FIG. 14, in the effect ball guidance effect process control in S <b> 6, first, the ball exit for discharging the effect ball DB is set based on, for example, the upper intermediate ball exit 50 c and the lower intermediate ball exit based on the table of FIG. 15. 50d or the lower ball outlet 50b is selected (S10). As shown in FIG. 15, when the player loses in the big hit lottery and loses, either the upper intermediate ball exit 50c or the lower intermediate ball outlet 50d is selected. If either one of the lower ball exits 50b is selected and lost in the probability variation lottery and the probability is low, if either the upper intermediate ball exit 50c or the lower intermediate ball exit 50d is selected and selected and the probability is high, Either the lower half ball exit 50d or the lower ball exit 50b is selected.

  Also, for example, when 8R is selected in the round number lottery, either the upper halfway ball exit 50c or the lower halfway ball exit 50d is selected, and when 16R is selected, any of the lower halfway ball exit 50d or the lower ball exit 50b is selected. Is selected. When 0 is selected in the auxiliary game frequency lottery, the upper halfway exit 50c is selected, when 50 or 100 is selected, the lower halfway exit 50d is selected, and 10,000 is selected, The ball outlet 50b is selected. As described above, the more the ball outlet located at the lower position is selected, the higher the possibility of shifting to a state advantageous to the player.

  As shown in FIG. 14, after the ball exit is selected in S10, it is determined whether or not it is the introduction timing of the effect ball DB (S11). If S11; Yes, the effect ball introduction mechanism 71 is activated (S12), As a result, the effect ball DB is introduced into the spiral passage 60a from the upper sphere entrance 50a of the guide cylinder 50, and the rotation of the spiral rotator 60 is started (S13). It is displayed (S14).

  In the ball exit correspondence display of the image display 14 in S14, the lottery results indicated by the upper halfway ball exit 50c, the lower halfway ball exit 50d, and the lower ball exit 50b are displayed based on the table of FIG. For example, with regard to the big hit lottery, as shown in FIG. 16, “losing” is set for the upper halfway exit 50c, “missing or big hit” is set for the lower halfway exit 50d, and “big hit” is set for the lower setting 50b. These are displayed in an easy-to-understand manner in association with each other using arrows or the like.

  As shown in FIG. 14, when the ball entrance SW90 is turned on after S14 (S15; Yes), the position of the effect sphere DB is estimated based on the rotation speed and the rotation direction of the spiral rotating body 60. (S16). Next, based on this estimation, it is determined whether or not the game ball DB is in the vicinity of the upstream side of the upper halfway ball exit 50c (S17). If S17; No, the game ball DB is located upstream of the lower halfway ball exit 50d. It is determined whether or not the position is near (S18).

  When the game ball DB is located near the upstream side of the upper halfway ball exit 50c (S17; Yes), and when the upper halfway ball exit 50c is selected in S10 (S19; Yes), the upper halfway discharge shown in FIG. 9 can be performed. When the state is switched to the state (S21), the effect ball DB is discharged from the upper halfway ball exit 50c, and when the upper halfway ball exit 50c is not selected in S10 (S19; No), it is shown in FIG. The state is switched to the lower middle dischargeable state (S22), and the effect ball DB passes through the upper middle ball outlet 50c.

  When the game ball DB is in a position near the upstream side of the lower halfway ball exit 50d (S18; Yes), if the lower halfway ball exit 50c is selected in S10 (S20; Yes), the lower halfway discharge shown in FIG. The state is switched to the state (S22), and the effect ball DB is discharged from the lower halfway ball exit 50d. If the lower halfway ball exit 50d is not selected in S10 (S20; No), it is shown in FIG. The state is switched to the upper middle dischargeable state (S21), and the effect ball DB passes through the lower middle ball outlet 50d and is finally discharged from the lower ball outlet 50b.

  When the game ball DB is not in the vicinity of any of the upper halfway ball exit 50c and the lower halfway ball exit 50d (S17; No, S18; No), when the effect button 31 is operated (S23; Yes), the spiral rotating body At least one of the rotation speed and the rotation direction of 60 is changed (S24). After S21, S22, S24, S23; No, the process proceeds to S25. In S25, it is determined whether or not any of the ball outlets SW91, 92, 93 is on. If S25; No, the process returns to S16.

  When any of the ball outlets SW91, 92, 93 is turned on (S25; Yes), the effect ball DB is discharged to the outside of the guide cylinder 50, and then the rotation of the spiral rotating body 60 is stopped ( In step S26, the effect ball collection mechanism 75 is operated (S27), whereby the effect ball DB discharged from the ball outlets 50b, 50c, and 50d is collected, transported to the effect ball exit ball introduction mechanism 71, and the effect ball is introduced. It is held by the mechanism 71 and is ready for the next operation.

The operational effects of the sphere guidance device 16 described above will be described.
The ball guiding device 16 includes a guide cylinder 50, a spiral rotating body 60, a production ball introduction / recovery mechanism 70, a rotation drive mechanism 80, and a sub-control device 25. The guide cylinder 50 has upper ball inlets 50a at both upper and lower ends. A lower sphere outlet 50b and an upper intermediate sphere outlet 50c and a lower intermediate sphere outlet 50d are provided in the middle in the height direction between the upper sphere inlet 50a and the lower sphere outlet 50b. Since the spiral rotating body 60 is rotatably accommodated and supported, and the spiral rotating body 60 forms a spiral passage 50a inside the guide cylinder 50, the effect introduction / recovery mechanism 70 causes the guide cylinder 50 to have an upper ball entrance 50a. When the effect ball DB is introduced into the spiral passage 60a, the effect ball DB falls while rotating the spiral passage 60a. At this time, the sub-control device 25 controls the rotation drive mechanism 80, and this rotation drive. By rotating and driving the spiral rotator 60 by the structure 80, it is possible to perform the spherical guidance of the unique production sphere DB in which the spiral rotator 60 (that is, the spiral passage 60a) also rotates, and in the spiral passage 60a. It is possible to perform a novel distribution in which the effect ball discharge position for discharging the effect ball DB to the outside of the guide cylinder 50 is changed in the height direction.

  Since this ball guiding device 16 guides the effect ball DB other than the game ball B launched on the game board 4, when the spiral rotating body 60 is rotationally driven, the rotational operation of the spiral rotating body 60 is periodically performed. The effect ball DB in the spiral passage 60a can be freely operated without giving the characteristics, and therefore the effect ball DB in the spiral passage 60a can be used as the lower ball exit 50b and the upper halfway ball exit 50c. And the stage ball discharge position so as to be discharged from any one of the ball outlets 50b or 50c or 50d selected in association with the winning of the game ball B to the start winning ports 10a and 10b in the lower half ball outlet 50d. Is rotated in the height direction in association with the winning of the game ball B to the start winning opening 10a, 10b, the rotation drive mechanism 80 is controlled by the sub-control device 25, and the guide cylinder 50 is placed on the game board 5. Setting Since the player is transparent, the player can see that the effect ball DB inside the guide cylinder 50 is guided, and the effect ball DB is discharged from any of the lower ball exit 50b, the upper intermediate ball outlet 50c, and the lower intermediate ball outlet 50d. Since the state of being played can be seen, the game effect effect by the guidance of the effect ball DB can be enhanced.

  The sub-control device 25 controls the rotation phase of the spiral rotator 50 from the rotation reference position, so that the effect ball DB in the spiral passage 60a can be discharged from the upper middle ball outlet 50c, and the upper half of the state can be discharged. Since the production ball DB in the passage 60a can pass through the upper middle ball outlet 50c and can be selectively switched to the lower middle dischargeable state that can be discharged from the lower middle ball exit 50d, the production ball DB is When it is located at least near the upstream side of the upper middle ball outlet 50c, the effect ball DB can be reliably discharged from the upper middle ball outlet 50c by switching to the upper middle ball dischargeable state. Since the effect ball DB passes through the upper halfway ball exit 50c by switching to the possible state, after that, when the production ball DB is located near the upstream side of at least the lower halfway ball exit 50d, the lower halfway By switching to the exitable state, the effect ball DB can be reliably discharged from the lower intermediate ball exit 50d, and the effect ball DB can also pass through the lower intermediate ball exit 50d. It is possible to reliably discharge from the outlet 50b. In this way, the production ball DB in the spiral passage 60a is reliably discharged from the upper intermediate ball outlet 50c, the lower intermediate ball outlet 50d or the lower ball outlet 50b selected in association with the winning of the game ball B to the start winning ports 10a and 10b. can do.

  The jackpot lottery is performed in response to the winning of the game ball B at the start winning ports 10a and 10b, and the jackpot condition is established when the winner is won by the jackpot lottery. The sub-control device 25 displays the result of the jackpot lottery. Since control is performed so that the production ball DB in the spiral passage 60a is discharged from the ball outlet 50b, 50c, or 50d set as suggested, the presence / absence of this big hit lottery, the winning expectation degree, and the like are determined via the production ball discharge position. The player can be notified and the effect of the big hit lottery can be enhanced.

  A chance variation lottery will be performed in conjunction with the winning of the jackpot lottery, and when winning in the probability variation lottery, the winning probability of the jackpot lottery will be set to a predetermined low probability, and if winning in the probability variation lottery will be set to a higher probability than the low probability The sub-control device 25 controls to discharge the effect ball DB in the spiral passage 60a from the ball outlet 50b, 50c or 50d set so as to suggest the result of the probability variation lottery. It is possible to notify the player of the presence / absence of winning, the expected degree of winning, etc. to the player via the effect ball discharge position, thereby enhancing the effect of the probability variation lottery.

  A lot number lottery is performed in conjunction with the winning of the big hit lottery, and the number of rounds that the big winning opening 11a is opened for a predetermined time or more during the big hit game is selected by this round number lottery. Since the production ball DB in the spiral passage 60a is controlled to be discharged from the ball outlet 50b or 50c or 50d set so as to suggest the result of the number lottery, the number of rounds selected in the round number lottery, etc. The player can be notified through the effect ball discharge position, and the effect of the lot number lottery can be enhanced.

  Auxiliary game number lottery is performed in conjunction with the winning of the big hit lottery, and the auxiliary game number lottery is selected to select the number of auxiliary games that increase the winning percentage of the game ball B that wins the start winning port 10b after the big hit game. The sub-control device 25 performs control so that the effect ball in the spiral passage 60a is discharged from the ball outlet 50b, 50c or 50d set so as to suggest the result of the auxiliary game number lottery. It is possible to notify the player of the number of auxiliary games selected in (1) via the effect ball discharge position, thereby enhancing the effect of the auxiliary game frequency lottery.

  An effect button 31 that can be operated by the player is provided, and the sub-control device 25 receives the signal indicating that the effect button 31 has been operated, and controls to change at least one of the rotation speed and the rotation direction of the spiral rotating body 60. Therefore, when the player operates the effect button 31, the rotation speed and the drop speed of the effect ball DB in the spiral passage 60a can be changed, and the player's sense of participation can be enhanced.

In addition, you may change the said Example as follows.
(1) One intermediate ball outlet is provided between the upper ball inlet 50a and the lower ball outlet 50b. In this case, the sub-control device 25 controls the rotational phase from the rotation reference position of the spiral rotator 60, so that the effect sphere DB in the spiral passage 60a can be ejected from the midway sphere exit and in the midway dischargeable state. It is configured to be selectively switchable to a state in which discharge is not possible on the way through the outlet.
(2) Three or more intermediate ball outlets are provided between the upper ball inlet 50a and the lower ball outlet 50b.

(3) An upper halfway proximity SW that detects a game ball DB at a position near the upstream side of the upper halfway ball exit 50c, and a lower halfway proximity SW that detects the game ball DB at a position near the upstream side of the lower halfway ball exit 50d, Provided on the inner surface of the guide cylinder 50. In this case, in the process control of FIG. 14, it is not necessary to estimate the position of the game ball in S16. In S17, it is determined whether the upper halfway proximity SW is on. In S18, whether the lower halfway proximity SW is on. It becomes the judgment. As a result, the effect ball DB can be more reliably discharged from the selected ball outlet.
