Upon the execution of the subtracting operation mentioned above, the winning notification processor 504 transmits the value of the accumulated gaming value, resulting from the subtraction, to the respective slot machines 1 via the communication interfaces 501. This enables the player to know the remaining amount subsequent to the win payout of the Mystery jackpot in the respective slot machines 1.
As set forth above, with such Mystery jackpot system, since the occurrence of the win on the Mystery jackpot is notified to the slot machine, in which the win occurs, and the other slot machines (i.e., slot machines with no occurrence of the win), not only the player, who won in the credit, but also players (players who lost in the credit) of the other slot machines 1 and a gallery who watches over a progress of the game practiced by the players are able to easily confirm, with either the liquid crystal display device 3 or the liquid crystal display device 4, when the Mystery jackpot, indicative of the accumulated gaming value, is obtained. This provides a capability of providing an increase in interests of the player, who obtained the Mystery jackpot, to bring a lot of excitations in seasoning. Moreover, under circumstances where a plurality of the Mystery jackpots are set in the same Mystery jackpot system, the presence of the winning can be notified for each Mystery jackpot that is set. This enables the player to easily confirm whether a common bonus, related to any of the progressive bonuses, is obtained.
[2. Example of Operation]
Now, an operation example of the Mystery jackpot system of the presently filed embodiment is described with reference to FIGS. 6A, 6B and 6C.
First, suppose that a predetermined collection executing condition, such as the start of variable movements of the symbols, occurs in a slot machine A (S601). The Mystery jackpot system is configured such that each slot machine 1 provides the management machine 300 with information of a collected gaming value, indicative of a predetermined gaming value, for each occurrence of the collection executing condition to allow the transferred collected gaming value to be accumulatively added in the management machine 300 whereby such “an accumulated gaming value” is credited to a winning object on condition of the occurrence of the winning. Upon the occurrence of the collection executing condition, the gaming values collected from the respective slot machines 1 are added to the cumulative collection value at such a time point. Also, the collection executing condition may be selected from those of various items.
Upon the occurrence of the collection executing condition, the slot machine A calculates the collected gaming value based on a predetermined calculation formula to cause the resultant calculated value to be notified with an adding request to the management machine 300 (S602).
Next, upon receipt of such notification, the management machine 300 operates at this point to add the notified collected gaming value to the accumulated gaming value stored in the accumulated gaming value storage device 503 (S603).
After the adding operation has been completed (S603), the management machine 300 provides an accumulated gaming value notification to all the slot machines 1 (including the slot machine A and a slot machine B in this example) notifying the accumulated gaming value that is updated upon executing the adding operation (S604, S606). Upon receipt of the notification, the slot machines 1 displays the notified updated accumulated gaming value as new amount of premium of the Mystery jackpot on the displays 3 or 4 of the respective slot machines 1 (S605, S607). This makes it possible for the respective players to grasp the present gaming values (premium), which can be obtained in the Mystery jackpot.
In the meanwhile, upon the occurrence of the collection executing condition, the other slot machine 1 (in this example, for example, the slot machine B) executes the operation to add the collected gaming value to the accumulated gaming value and the operation to notify the accumulated gaming value. That is, if the collection executing condition occurs on the slot machine B (S608), the slot machine B calculates the collected gaming value using a predetermined calculation formula or the like, giving notification of the resultant calculated value with an adding request to the management machine 300 (S609).
Next, upon receipt of the notification, the management machine 300 adds the collected gaming value, which is notified from the slot machine B, to the accumulated gaming value already stored in the accumulated gaming value storage device 503 at this time point (S610).
After the adding operation has been completed (S610), the management machine 300 provides the accumulated gaming value notification to notify the respective slot machines A and B with the accumulated gaming value updated upon execution of the adding operation (S611, S655). Upon receipt of this notification, the respective slot machines 1 display the updated accumulated gaming value as new amounts of premium of the Mystery jackpot on the displays 3 or 4 of the respective slot machines 1 (S613, S614). This makes it possible for the respective players to grasp the present gaming value, to be obtained by the Mystery jackpot.
Thus, each time the collection executing condition occurs in the respective slot machines 1, the collected gaming value is added to the accumulated gaming value stored in the management machine 300, increasing the value of the accumulated gaming value until the accumulated gaming value is paid out.
By the way, with the Mystery jackpot system, the respective slot machines 1 always monitor whether or not a predetermined primary lottery condition occurs.
Although the primary lottery condition may include any kind of conditions, in this example, the respective slot machines are supposed to perform random lotteries using the random numbers that are triggered when the variable displays of the symbols are started.
Now, suppose that with the slot machine A, the SPIN/REPEAT switch 37 is pressed to start the variable displays of the symbols with the resultant occurrence of the primary lottery condition (S616). This occurrence is detected by the primary lottery execution section 404 of the slot machine A, by which the primary lottery is executed (S617). Here, a credit was lost in the outcome of the primary lottery (S618). The slot machine A terminates the lottery of the Mystery jackpot without sending any notification to the management machine 300.
Next, description is made of an operation example of the slot machine 1 in cases, where the credit is won in the primary lottery but lost in the secondary lottery, taking the slot machine B as an example.
First, like the manner as set forth above, it is supposed that with the slot machine B, the SPIN/REPEAT switch 37 is pressed to start the variable displays of the symbols with the start of the primary lottery condition (S619). This occurrence is detected by the primary lottery execution section 404 of the slot machine B by which the primary lottery is executed (S620). Meanwhile, with this example, it is also supposed that the result of the primary lottery of the S620 is won (S623). Then, the primary lottery execution section 404 of the slot machine B commands the secondary lottery execution section 405 to start the secondary lottery. The secondary lottery execution section 405 executes the secondary lottery in a method under which alternatives are provided to the player in response to the command, set forth above, for selection (S622). With this example, it is supposed that the credit is lost in the outcome of the secondary lottery (S623). As a result of secondary lottery, the slot machine B terminates the lottery on the Mystery jackpot without sending any notification to the management machine 300.
Next, description is made of operation examples of the slot machine 1 and the management machine 300 in cases where the credits are won in both outcomes of the primary and secondary lotteries to execute the payout of the Mystery jackpot.
First, suppose that with the slot machine A, the SPIN/REPEAT switch 37 is pressed to start the variable displays of the symbols with the start of the primary lottery condition (S624). With the slot machine A, the symbols are stopped and displayed after the start of the variable displays of the symbols, thereby executing an original gaming operations (not shown) of the gaming machine with the resultant occurrences of a normal winning and a bonus game depending on statuses of the symbols stopped in displays 3, 4.
Aside from the original gaming operation of the slot machine, the primary lottery execution section 404 of the slot machine A detects the occurrence of the primary lottery condition, upon which the primary lottery is executed (S625). Here, suppose that a credit is won in the outcome of the primary lottery (S626). Then, the primary lottery execution section 404 of the slot machine A commands the secondary lottery execution section 405 to begin the secondary lottery. The secondary lottery execution section 405 executes the secondary lottery in a method under which alternatives are provided to the player in response to the command, set forth above, for selection (S627). With this example, suppose that the credit is won in the outcome of the secondary lottery (S628). As a result of the secondary lottery, the payout of the Mystery jackpot for the slot machine A is decided.
Hereunder, an operation example, to be executed after the winning occurs on the secondary lottery, is described below with reference to FIG. 6C.
Now, after the outcome of the secondary lottery appears to be won (S628), the slot machine A, subjected to the occurrence of the winning, transmits a winning occurrence notification to the management machine 300 (S629).
Upon receipt of the winning occurrence notification, the management machine 300 provides notification to the slot machine A, to which the accumulated gaming value is to be paid out, with a prize gaming value which is a whole of or a part of the value of the accumulated gaming values stored in the accumulated gaming value storage device 503 (S630).
Upon receipt of the notification of the prize gaming value, the slot machine A executes a credit adding operation (S631). That is, the slot machine 1 executes the operation to add the value of the prize gaming value, notified from the management machine 300, to the value (values of coins, already inserted by the player, and a credit) of the credit stored at the time when the notification is received and a value, resulting from the addition, is stored and kept as a value of a new credit. That is, this results in a capability for the player to receive the payment of the credit or the like resulting from the winning on the so-called jackpot.
Further, the slot machine A performs the credit adding operation (S631), while executing an own winning effect (S632). For instance, the effect controller 40 of the slot machine A is started up to provide effects in such a way to cause the LEDs 57 to be blinked in a predetermined pattern and cause the speaker 59 to sound a fanfare, a winning blessing music, etc., while providing a display of a message “CONGRATURATION! YOU WIN MYSTERY JACKPOT! WINNING CREDIT IS ◯◯◯◯!” or the like on the liquid crystal displays 3 or 4.
By the way, upon receipt of the winning occurrence notification in step S629, the management machine 300 transmits a winning occurrence notification to allow the player of the other slot machine B to be notified with the occurrence of winning (S633). Upon receipt of such a winning occurrence notification, the slot machine B renders the effect controller 406 operative to start up, thereby causing a winning notification effect to be executed. For instance, various effects are executed such that the LEDs 57 are blinked in a predetermined pattern while providing a display of a message “SOMEBODY HITS MYSTERY JACKPOT! ”, etc., on the liquid crystal displays 3 or 4.
Next, the management machine 300 regulates a value, stored in the accumulated gaming value storage device 503, in association with the credit adding operation of the slot machine A in which the winning occurs, thereby executing a subtracting operation of the value of accumulated gaming value (S635). The subtracting operation may include a method of resetting the value, stored in the accumulated gaming value storage device 503 to an initial value (an arbitrary value such as, for instance “0”, “100”, etc.) and it doesn't matter if a method is employed by which the amount of payment is subtracted from the value stored prior to the payment.
After the subtracting operation has been completed (S635), the management machine 300 transmits a residue accumulated gaming value notification, involving the accumulated gaming value, for the purposes of providing notification to the slot machines A, B with the value of the accumulated gaming value stored in the accumulated gaming value storage device 503 (S636, S638). Upon receipt of such notification, the slot machines A, B update the displays of the present accumulated gaming value (S637, S639). This makes it possible for the players of the respective slot machines A, B to grasp the present gaming value.
Also, the Mystery jackpot system repeatedly executes the operations to add the collected gaming values mentioned above, execute the lottery and payout the accumulated gaming value for the occurrence of the winning in subsequent stages, thereby continuously providing the players with entertaining and exciting values of a so-called Mystery jackpot game.
[3. Other Features]
While the presently filed embodiment has been described with reference to an example wherein the management machine 300 is comprised of a separate device independent from the slot machine 1, however it is also possible to provide the management machine 300 integrally formed with any one of the slot machines 1 constituting the Mystery jackpot system. For instance, a modified form of the presently filed embodiment may be considered to have a structure in which a board (such as a mother board), on which a microcomputer with a function corresponding to the management machine 300 is installed, is mounted on the slot machine 1 to allow the board to be connected to the microcomputer 61 of the slot machine 1.
According to the present invention, the Mystery jackpot system makes it possible to perform complicated lottery and effects without causing a host computer from bearing a load. Also, while the present invention has been described above taking a Pachi-Slot machine for domestic use as an example, the present invention may have application to slot machines manufactured for foreign countries.
