Description

    CROSS-REFERENCE TO RELATED APPLICATIONS
  • This application claims benefit of priority based on US Provisional Patent Application No. 61/038,983 filed on Mar. 24, 2008. The contents of this application are incorporated herein by reference in their entirety.
  • BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a slot machine capable of displaying a special picture consisting of a plurality of picture pieces and a control method thereof.
  • 2. Discussion of the Background
  • In conventional slot machines, when a player inserts game media such as medals, coins or bills into an insertion slot of the slot machine and presses a spin button, then a plurality of symbols are scroll-displayed to a display portion provided on the front surface of a casing and, thereafter, the respective symbols are automatically stopped, as disclosed in U.S. Pat. Nos. 6,960,133, 6,012,983 and 6,093,102. In this case, when scroll-display of respective symbols starts by an input from the spin button, symbols are selected using random numbers, and the selected symbols are stop-displayed to the display portion. Then, when a combination of the stop-displayed symbols along a winning line is a predetermined winning combination (prize), a payout is conducted.
  • Further, among conventional slot machines, there are some slot machines which conduct two types of payouts which are a payout determined according to the combinations of symbols rearranged along winning lines and a payout determined according to the number of displayed scatter symbols, as disclosed in U.S. Pat. No. 6,604,999 and US 2002-0065124-A1. In such a slot machine which conducts payouts based on such scatter symbols, there is no relationship between payouts and positions at which the scatter symbols are displayed.
  • Further, in the conventional slot machines, there exists a slot machine offering a predetermined profit different from a normal payout to a player.
  • For example, there exists a slot machine that reserves a part of a consumed credit and conducts a payout in such a large amount (so-called “jackpot”) as not to be paid out in the case of a normal winning, when a predetermined condition (for example, symbols being aligned in specific order) is satisfied.
  • Furthermore, there also exists a slot machine executing a game different from a basic game (in the present description, referred to as feature game, e.g. bonus game comparatively advantageous for the player). Examples of the feature game include a free game. The free game is a game that can be played without consuming game media. For example, a slot machine executing a free game as a secondary game in the case of establishment of a predetermined condition (symbols being aligned in a specific arrangement) in the basic game is disclosed in AU1972901-A1.
  • In such a slot machine that executes the feature game of this kind or generates a jackpot winning (slot machine offering a predetermined profit), the player normally plays the game expecting for receiving a profit of the feature game or the jackpot (predetermined profit).
  • However, such a slot machine is generally configured to execute the feature game or to generate the jackpot winning in the case that the symbols are aligned in a predetermined arrangement or in the case that specific symbols in a predetermined number are displayed. Here, the condition for offering of the predetermined profit is comparatively similar to the condition for offering of a normal payout in many cases. Accordingly, there tends to be happened a case where it is visibly unclear to the player that a display of which symbols in which arrangement leads to the predetermined profit. Consequently, it becomes hard to make the player have an expectation for the predetermined profit, so that there has been a problem that the slot machine fails to fully attract an interest of the player in the predetermined profit.
  • In light of the aforementioned problem, the present invention has been devised, and an object of the present invention is to provide a slot machine capable of fully attracting an interest of a player in a predetermined profit different from a normal payout and a control method thereof.
  • The contents of U.S. Pat. No. 6,960,133, U.S. Pat. No. 6,012,983, U.S. Pat. No. 6,093,102, U.S. Pat. No. 6,604,999, U.S. 2002-0065124-A1, and AU1972901-A1 are incorporated herein by reference in their entirety.
  • SUMMARY OF THE INVENTION
  • The present invention provides a slot machine having the following configuration.
  • That is, the slot machine comprises: a symbol display capable of variably displaying a display object showing a normal symbol and a picture piece for forming a predetermined picture; and a controller. The controller is programmed to execute processing of (A) stop-displaying at least a plurality of the display objects after variably displaying the plurality of the display objects, to the symbol display, (B) offering a normal payout corresponding to the normal symbols shown by the display objects stop-displayed in the processing (A) or a combination of the normal symbols, and (C) offering a predetermined profit different from the normal payout, as triggered by formation of the predetermined picture by the picture pieces shown by the display objects stop-displayed in the processing (A).
  • According to the slot machine, the display object may be stop-displayed to the symbol display. The display object shows a picture piece for forming a predetermined picture. In the case that the picture pieces shown by the display objects stop-displayed to the symbol display form the predetermined picture, a predetermined profit (for example, a feature game or a payout of a coin according to a jackpot) different from a normal payout is offered. Namely, a condition for offering of the predetermined profit is a display of the predetermined picture to the symbol display (in the present description, also referred to as “completion of a predetermined picture”), which is different from a mere arrangement or a mere number of the symbols and is visibly very clear to the player.

Specifically, when the hopper 66 is filled with coins, a regular coin is distributed into the cash box by the reverter 21S. On the other hand, when the hopper 66 is not filled with coins, the regular coin is distributed into the hopper 66. The cold cathode tube 81 functions as a backlight installed on the rear face side of the lower image display panel 16 and the upper image display panel 33, and lights up based on a control signal to be outputted from the main CPU 41.
  • Next, processing executed in the slot machine 10 will be described.
  • FIG. 4 is a flowchart illustrating main processing executed in the slot machine 10 according to a first embodiment.
  • First, in the slot machine 10, activation processing is executed (step S101). The activation processing will be specifically described later by using FIG. 9 to FIG. 11.
  • After the activation processing, the main CPU 41 executes processing of addition of the number of credits stored in the RAM 43 as an interrupt processing, on receiving a detection signal outputted from the coin counter 21C when the coin inserted into the coin receiving slot 21 is detected by the coin counter 21.
  • After the processing of step S101, the main CPU 41 determines whether or not a free game flag is set (step S102). The free game flag is a flag to be set as triggered by the completion of the picture 110 (see FIG. 1D) and is a flag indicating that it is currently the free game period (see step S29 in FIG. 6).
  • When determining that the free game flag is not set, the main CPU 41 executes normal game execution processing (step S200). The normal game execution processing will be specifically described later by using FIG. 5 and FIG. 6. After executing the processing of step S200, the main CPU 41 returns the processing to step S102.
  • When determining that the free game flag is set, the main CPU 41 executes free game execution processing (step S300). The free game execution processing will be specifically described later by using FIG. 8. After executing the processing of step S300, the main CPU 41 returns the processing to step S102.
  • Hereinafter, there will be described the slot machine game execution processing (the normal game execution processing and the free game execution processing) performed in the slot machine 10.
  • The main CPU 41 reads a game program and executes the game program to progress a slot machine game.
  • FIG. 6 is a flowchart illustrating a subroutine of slot machine game execution processing.
  • FIG. 7 is a view illustrating a relation among a type and a number of rearranged normal symbols and a number of coin-outs.
  • First, the main CPU 41 determines whether or not a coin has been BET (step S11). In the processing, the main CPU 41 determines whether or not to have received an input signal outputted from the 1-BET switch 26S when the 1-BET button 26 is operated or an input signal outputted from the maximum BET switch 27S when the maximum BET button 27 is operated. When determining that a coin has not been BET, the main CPU 41 returns the processing to step S11.
  • On the other hand, when determining that a coin has been BET in step S11, the main CPU 41 executes processing for making a subtraction from the number of credits stored in the RAM 43, according to the number of BET coins (step S12). It should be noted that, when the number of BET coins is larger than the number of credits stored in the RAM 43, the main CPU 41 does not execute the processing for making a subtraction from the number of credits stored in the RAM 43, and returns the processing to step S11. When the number of BET coins exceeds an upper limit of the number of coins that can be BET on a single game (50 coins in the present embodiment), the main CPU 41 does not execute the processing for making a subtraction from the number of credits stored in the RAM 43, and the processing is proceeded to step S13.
  • Next, the main CPU 41 determines whether or not the start button 23 has been turned on (step S13). In the processing, the main CPU 41 determines whether or not to have received an input signal outputted from the start switch 23S when the start button 23 is pressed.
  • When determining that the start button 23 has not been turned ON, the main CPU 41 returns the processing to step S11. It should be noted that, when the start button 23 is not turned ON (for example, when a command to end the game is inputted without pressing the start button 23), the main CPU 41 cancels a result of the subtraction obtained in step S12.
  • On the other hand, when determining in step S13 that the start button 23 has been turned ON, the main CPU 41 executes display-object rearrangement processing (step S14).
  • Here, the display-object rearrangement processing will be described by using FIG. 6.
  • First, the main CPU 41 executes display-object determination processing (step S20). In the processing, the main CPU 41 determines the display object to be rearranged in the symbol matrix SM by executing the display-object selection program described above.
  • Next, the main CPU 41 starts scroll-display of the display objects and rearranges the display objects in the first display area 100A to the third display area 100C based on the determination result in step S20 (step S21).
  • Next, the main CPU 41 determines whether or not the rearrangement is in the li-zhi state for the completion of the picture 110 (see FIG. 1D) (step S22). Namely, the main CPU 41 determines whether or not the six display objects rearranged in the second display area 100B and the third display area 100C are the display objects for forming the picture 110.
  • When determining that the rearrangement is not in the li-zhi state for completion of the picture 110, the main CPU 41 rearranges the display objects in the fourth display area 100D to the fifth display area 100E (step S23) and terminates the present subroutine.
  • On the other hand, when determining that the rearrangement is in the li-zhi state for the completion of the picture 110, the main CPU 41 displays the li-zhi effect image 130 and the li-zhi text image 120 (see FIG. 1B) to the lower image display panel 16 (step S24).
  • Next, the main CPU 41 rearranges the display objects in the fourth display area 100D (step S25).
  • Then, the main CPU 41 determines whether or not the picture 110 is completed. Namely, the main CPU 41 determines whether or not the nine display objects rearranged in the second display area 100B to the fourth display area 100D are the display objects for forming the picture 110.
  • When determining that the picture 110 is not completed, the main CPU 41 displays the bad-luck image 121 (see FIG. 1C) to the lower image display panel 16 (step S27).
  • On the other hand, when determining that the picture 110 is completed, the main CPU 41 displays the picture-completion effect image 131 and the picture-completion text image 122 (see FIG. 1D) to the lower image display panel 16 (step S28).
  • Thereafter, the main CPU 41 sets the free game flag (step S29) and sets the remaining number T of the free game to T=C in the number-of-free-game storage area in the RAM 43 (step S30).
  • After executing the processing of step S27 or step S30, the main CPU 41 rearranges the display object in the fifth display area 100E (step S31) and terminates the present subroutine.
  • The display-object rearrangement processing executed in step S14 in FIG. 5 has been described by using FIG. 6.
  • After executing the processing of step S14, the main CPU 41 determines whether or not a prize is established (step S15). Here, the establishment of the prize refers to the rearrangement of two or more normal symbols of at least one type, out of “10”, “J”, “Q”, “K”, “UMBRELLA”, “CLOUD”, “THUNDER”, and “SUN”, in the symbol matrix SM (see FIG. 7). In the processing, the main CPU 41 counts the number of normal symbol for each type, with regard to the rearranged display objects in step S14. Then, the main CPU 41 determines whether or not the counted number is equal to or more than two.
  • When determining that the prize has been established, the main CPU 41 executes processing according to payout of the coin (step S16). In the processing, the main CPU 41 determines the number of coin-outs based on the type and the number of rearranged normal symbols with reference to the odds data (see FIG. 7A) stored in the RAM 43.
  • For example, in the case that two “SUN” are rearranged when 2 coins are BET, the number of coin-outs is 50 (=25×2).
  • Here, in the case that the odds symbol is rearranged in the symbol matrix SM, the number obtained by multiplying the number calculated based on the type and the number of the normal symbols by 3.
  • In the case of accumulating the coin, the main CPU 41 executes processing for adding a number of credits corresponding to the determined number of coin-outs. On the other hand, in the case of paying out coins, the main CPU 41 transmits a control signal to the hopper 66 in order to pay out the coin in number corresponding to the determined number of coin-outs.
  • When determining that the prize has not been established in step S15, or after executing the processing of step S16, the main CPU 41 terminates the present subroutine.
  • FIG. 8 is a flowchart illustrating a subroutine of free game execution processing.
  • First, the main CPU 41 executes the processing of step S41 to step S42, and since the processing is virtually the same processing as the processing of step S13 to step S14 in FIG. 5, the description thereof is omitted here.
  • Next, the main CPU 41 determines whether or not the first special picture is completed (step S43). Namely, the main CPU 41 determines whether or not the nine display objects rearranged in the second display area 100B to the fourth display area 100D are the display objects for forming the picture 111.
  • When determining that the first special picture is completed, the main CPU 41 conducts the progressive jackpot (step S44). The number of coin to be paid out in the progressive jackpot is a number corresponding to the value obtained by adding an initial payout value to an integration value (the integration value of a part of the number of inserted game media) stored in the RAM 43, and the payout is conducted as a hand pay. Examples of the processing conducted by the main CPU 41 in step S44 include output of a notification sound from the speaker 29, lighting of the lamp 30, print of the ticket 39 with a barcode indicative of the number of coin-outs, and the like.
  • Since the slot machine 10 is a stand-alone type slot machine, a value obtained by adding the initial payout value to the integration value (the integration value of a part of the number of inserted game media) on a single slot machine 10 is adopted as the payout of the progressive jackpot.
  • However, in the present invention, the integration value adopted in the progressive jackpot is not limited to this example. For example, in the case that the slot machine is connected to a network, there may be adopted an integration value on the slot machines of the same type in a single casino, an integration value on the slot machines of the same type provided in the same area (for example, state and country), and the like.
  • When determining that the first special picture is not completed, the main CPU 41 determines whether or not the second special picture is completed (step S45). Namely, the main CPU 41 determines whether or not the nine display objects rearranged in the second display area 100B to the fourth display area 100D are the display objects for forming the picture 112.
  • When determining that the second special picture is completed, the main CPU 41 sets the remaining number T of the free game to T=T+C in the number-of-free-game storage area in the RAM 43 (step S46).
  • When determining that the second special picture is not completed in step S45, or after executing the processing of step S44 or step S46, the main CPU 41 executes processing of step S47 to step S48. Since the processing is virtually the same processing as the processing of step S15 to step S16 in FIG. 5, the description thereof will be omitted here.
  • When determining that the prize has not been established in step S47, or after executing the processing of step S48, the main CPU 41 sets the remaining number T of the free game to T=T−1 in the number-of-free-game storage area in the RAM 43 (step S49).
  • Next, the main CPU 41 determines whether or not T is zero (T=0) (step S50). When determining that T is not zero, the main CPU 41 terminates the present subroutine. On the other hand, when determining that T is zero, the main CPU 41 clears the free game flag (step S51) and terminates the present subroutine.
  • Subsequently, there will be described activation processing (see step S101 in FIG. 5) by using FIG. 9 to FIG. 11.
  • FIG. 9 is a flowchart illustrating a procedure of activation processing. This activation processing is the processing conducted by the mother board 40 and the gaming board 50. It should be noted that the memory card 53 is inserted into the card slot 53S in the gaming board 50, and the GAL 54 is mounted onto the IC socket 54S.
  • First, when a power switch is turned on (power is turned on) in the power supply unit 45, the mother board 40 and the gaming board 50 are activated (steps S1-1, S2-1). Inactivation of the mother board 40 and the gaming board 50, individual processing is respectively executed in parallel. Namely, in the gaming board 50, the CPU 51 reads the auxiliary authentication program stored in the boot ROM 52, and conducts auxiliary authentication according to the read auxiliary authentication program, to previously check and prove that the authentication program is not falsified before loading the program to the mother board 40 (step S2-2). Meanwhile, in the mother board 40, the main CPU 41 executes the BIOS stored in the ROM 42, and expands compressed data which is incorporated in the BIOS into the RAM 43 (step S1-2). The main CPU 41 then executes the BIOS expanded into the RAM 43 to diagnose and initialize a variety of peripheral devices (step S1-3). The processing of step S1-3 will be specifically described later with reference to FIG. 12.
  • Since the ROM 55 of the gaming board 50 is connected to the main CPU 41 via the PCI bus, the main CPU 41 reads the authentication program stored in the ROM 55, and stores the read authentication program into the RAM 43 (step S1-4). At this time, according to the standard BIOS function of BIOS, the main CPU 41 takes a checksum by ADDSUM system (normal checking system) and stores the authentication program into the RAM 43, while conducting processing for confirming whether or not the storage is certainly conducted.
  • Next, after confirming what is connected to the IDE bus, the main CPU 41 accesses, via the IDE bus, the memory card 53 inserted in the card slot 53S, to read a game program or a game system program from the memory card 53. In this case, the main CPU 41 reads data constituting the game program and the game system program by 4 bytes. Subsequently, the main CPU 41 conducts authentication to check and prove that the read game program and game system program have not been falsified, following the authentication program stored in the RAM 43 (step S1-5). When this authentication processing is normally completed, the main CPU 41 writes and stores the game program and the game system program, which have been the authentication targets (which have been authenticated), into the RAM 43 (step S1-6). Next, the main CPU 41 accesses, via the PCI bus, the GAL 54 mounted on the IC socket 54S, reads payout ratio setting data from the GAL 54, and writes and stores the data into the RAM 43 (step S1-7). Subsequently, the main CPU 41 conducts processing for reading country identification information stored in the ROM 55 of the gaming board 50 via the PCI bus, and writes and stores the read country identification information into the RAM 43 (step S1-8).
  • After conducting the above-mentioned processing, the main CPU 41 sequentially reads and executes the game program and the game system program, thereby execute insurance setting processing and game execution processing.
  • FIG. 10 is a chart illustrating a procedure of peripheral-device initialization processing.
  • First, the main CPU 41 diagnoses and initializes a reel-related device (step S3-1). In this processing, the main CPU 41 sequentially transmits request signals to the index detecting circuit 65, the position-change detecting circuit 71, and the motor driving circuit 62. Then, the main CPU 41 determines whether or not to have received predetermined response signals and conducts clearance of a predetermined storage area, and the like.
  • Next, the main CPU 41 diagnoses and initializes a display (step S3-2). In this processing, the main CPU 41 transmits the request signal to the graphic board 68. Then, the main CPU 41 determines whether or not to have received a predetermined response signal and conducts clearance of a predetermined storage area, and the like.
  • Next, the main CPU 41 diagnoses and initializes various types of input devices (step S3-3). In this processing, the main CPU 41 transmits request signals to the input devices such as the spin switch 23S, the change switch 24S, the CASHOUT switch 25S, the 1-BET switch 26S, the maximum BET switch 27S, and the touch panel 11, and then determines whether or not to have received predetermined response signals.
  • Subsequently, the main CPU 41 diagnoses and initializes other peripheral devices connected to the main CPU 41 (step S3-4). Then the present subroutine is terminated.
  • In the present embodiment, there has been described the case where the slot machine 10 is a stand-alone type slot machine. However, in the present invention, a plurality of slot machines may be connected to a central controller via a network and controlled by the central controller.
  • FIG. 11 is a chart illustrating a procedure of activation processing executed by the central controller.
  • First, when the power switch is turned on (the power is turned on) in the power unit, a mother board is activated (step S4-1).
  • In the mother board, a CPU executes a BIOS stored in a ROM so as to expand compressed data incorporated in the BIOS into a RAM (step S4-2). Then, the CPU executes the BIOS expanded into the RAM, and then, diagnoses and initializes various types of peripheral devices such as a display (step S4-3).
  • Next, the CPU executes initialization processing of each slot machine. In this processing, the CPU establishes a network connection between the central controller and each slot machine, and diagnoses if the network functions properly.
  • After the above-described processing, the CPU controls proceeding of the game executed in a plurality of the slot machines by reading and executing a game control program.
  • As above described, according to the slot machine 10 of the present embodiment, the display objects may be rearranged in the symbol matrix SM. Among these display objects, there exists the display object showing the picture piece for forming the predetermined picture (picture 110). Then, the free game is executed in the case that the picture pieces shown by the display objects rearranged in the symbol matrix SM form the predetermined picture. Namely, a condition for generation of the free game is a display of a predetermined picture in the symbol matrix SM, and the condition is different from a mere arrangement or a mere number of the symbols and is visibly very clear to the player. Accordingly, it is easier to have the player have an expectation for the completion of such a predetermined picture, and player's interest in the free game can be fully attracted.
  • Further, according to the slot machine 10 of the present embodiment, the picture 110 as a trigger for generating the free game is displayed in the predetermined display area (the second display area 100B to the fourth display area 100D) in the symbol matrix SM. Accordingly, the player's attention can be concentrated on such areas. Accordingly, it is possible to have the player absorbed in the game.
  • Furthermore, according to the slot machine 10 of the present embodiment, the display objects are sequentially rearranged in the second display area 100B to the fourth display area 100D, in which the picture 110 may be displayed. When the display objects are rearranged in the second display area 100B and the third display area 100C, if the picture pieces shown in the rearranged display objects form the picture 110 to be completed when the picture piece for forming the picture 110 is stop-displayed in the fourth display area 110D (namely, in the case of the li-zhi state for completion of the predetermined picture), the li-zhi effect image is displayed.
  • Accordingly, it is possible to increase the player's expectation for the completion of the picture 110, as well as evoking the player's attention on the predetermined picture.
  • Further, according to the slot machine 10 of the present embodiment, as triggered by the formation of the picture 111 by the picture pieces shown in the display objects rearranged in the free game, a payout of the progressive jackpot is conducted. Further, as triggered by the formation of the picture 112 by the picture pieces shown in the display objects rearranged in the free game, the remaining number of the free game is increased. Accordingly, it becomes possible to have the player have an expectation for the completion of the picture 111 or the picture 112 in the free game, so that the player's interest in the free game can be fully attracted. Moreover, it becomes possible to significantly increase the player's interest in the completion of the picture 110 in the normal game, so that the player can be absorbed in the game.
  • In the above-described embodiment, there has been described the case where the symbols (the normal symbol and the special symbol) are rearranged in the symbol matrix SM in the lower image display panel 16 (the case where the slot machine 10 is a so-called video slot machine). However, a slot machine of the present invention may be configured such that the symbols (the normal symbol and the special symbol) are stop-displayed by using a so-called mechanical reel.
  • In the following, a slot machine 310 having such a configuration will be described.
  • It is to be noted that in the following, the same constituents as those of the slot machine 10 according to the first embodiment are described while provided with the same numerals.
  • Further, a description will be omitted as for a part to which the description of the slot machine 10 is applicable.

On the outer peripheral surfaces of the reels 314A, 314B, 314C, 314D and 314E, there are drawn display objects sequences constituted by display objects each showing normal symbols only, such as “10”, “J”, “Q”, “K”, “UMBRELLA”, “CLOUD”, “THUNDER”, and “SUN”, and the display objects each showing the normal symbols and the picture piece for forming the predetermined picture (the picture 110, the picture 112, the picture 112).
  • At the center portion of the lower image display panel 16, there is provided a display area 328 for displaying the symbols. Within the display area 328, there are formed five display windows 315 (315A, 315B, 315C, 315D and 315E) visible through their back surfaces. Further, the symbols drawn on the outer peripheral surfaces of the reels 314A, 314B, 314C, 314D and 314E are displayed on a three-by-three basis, through the display windows 315A, 315B, 315C, 315D and 315E.
  • An internal configuration and flowcharts of the slot machine 310 are virtually the same as those in the above-described embodiment, and therefore, the description thereof will be omitted here.
