Next, the internal configuration of the above-mentioned slot machine 1 will be described with reference to
The controller 41 has a main CPU 42, a RAM 43 and a ROM 44. The main CPU 42 operates in accordance with the programs stored in the ROM 44 and performs signal input and output with respect to the other constituent elements through an I/O port 49. Specifically, the main CPU 42 controls the operation of the entire slot machine 1. The RAM 43 stores data and programs to be used when the main CPU 42 is operating. For instance, the RAM 43 temporarily retains the random number values which have been sampled by the sampling circuit 46 after the game has started. The RAM 43 stores code numbers corresponding to the respective reels 101 through 105. The ROM 44 stores various types of programs that will be executed by the main CPU 42, as well as permanent data.
More particularly, the programs stored in the ROM 44 include game programs and game system programs (hereinafter referred to as game programs or the like). Further, the game programs include lottery programs as will be described later.
The lottery programs are used to determine the code numbers corresponding to symbols to be displayed on center positions of each reel display portion 101 to 105 (namely, symbol display portion 111B, 112B, 113B, 114B, and 115B) of the variably display portion 3B.
This lottery program includes symbol weighing data. The symbol weighing data shows correspondence relationships between the respective code numbers and one or a plurality of random number values within a predetermined number value range (for instance 0 through 255). The probability of lottery with respect to each symbol is set by associating one or a plurality of random number values to one code number. The random number values are drawn by lottery and symbols which have been finally identified from the random number values are re-positioned on the variably display portion 3B. The lottery program for determining the symbols to be positioned may also employ weighing data in which the predetermined random number range is associated to the symbol combination. In this case, determined winning combination is displayed on the variably display portion 3B.
The random number generation circuit 45 operates in accordance with the commands from the main CPU 42 and generates random numbers within a predetermined range. The sampling circuit 46 selects, by lottery, an arbitrary random number from the random numbers generated by the random number generation circuit 45 in response to a command from the main CPU 42. At the same time, the sampling circuit 46 inputs the random number thus selected to the main CPU 42. The clock pulse generation circuit 47 generates a reference clock for causing the main CPU 42 to operate. The divider 48 inputs a signal obtained by dividing the reference clock by a constant frequency to the main CPU 42.
The main control board 71 is connected to the touch panel 4. As described above, the touch panel 4 is arranged at a front face of the variably display portion 3B and is adapted to identify a coordinate position of the portion that was touched by the player. Specifically, the touch panel 4 can discriminate the portion that the player has touched, and in what direction the touched portion was moved based on the coordinate position information that was thus identified. A signal in accordance with the above discrimination is then inputted to the main CPU 42 through the I/O port 49.
The main control board 71 is connected to the operation button 26 (the start button and the like, as mentioned above) and a signal in accordance with a depression operation of these buttons is inputted to the main CPU 42 through the I/O port 49.
The illumination effect driving circuit 61 outputs an effect signal for causing the light emitting portions 25 and the topper effect device 27 as mentioned above to perform illumination effects. The topper effect device 27 is connected in series with the illumination effect driving circuit 61 through the light emitting portions 25.
The hopper driving circuit 63 drives the hopper 64 under the control of the main CPU 42. As a result, the hopper 64 carries out an operation to payout coins to the coin payout opening. The payout completion signal circuit 65 receives coin amount value data from the coin detecting portion 24 to which it is connected. Then, when the received coin amount value has reached the set coin amount value, the payout completion signal circuit 65 inputs a signal that notifies completion of coin payout to the main CPU 42. The coin detecting portion 24 detects the number of coins that were paid out by the hopper 64 and then inputs coin amount value data showing the amount of coins that was detected to the payout completion signal circuit 65. The display portion driving circuit 67 controls the display operation of the respective display portions including the payout number display portion 5, the payout number display portion 6, and the like.
The main control board 71 is connected to the sub-control board 72. As shown in
The sub-micro computer 73 has a sub-CPU 74, a program ROM 75, a work RAM 76 and I/O ports 77 and 80. The sub-CPU 74 carries out a control operation in accordance with a control command transmitted from the main control board 71. Although the sub-control board 72 does not have a clock pulse generation circuit, a divider, a random number generation circuit and a sampling circuit, it is constituted so as to execute sampling of random numbers based on an operation program of the sub-CPU 74. The program ROM 75 stores a control program to be executed by the sub-CPU 74. The work RAM 76 is constituted as a temporary memory to be used by the sub CPU 74 in executing the control program.
The image control circuit 81 has an image control CPU 82, an image control work RAM 83, an image control program ROM 84, an image ROM 86, a video RAM 87 and an image control IC 88. The image control CPU 82 determines the image to be displayed on the upper display portion 3A and the variably display portion 3B based on the parameters set in the sub-micro computer 73 and the image control programs stored in the image control program ROM 84. For example, the upper display portion 3A displays a payout table and a help screen. The variably display portion 3B carries out scrolled display and stopped display on the respective symbol display portions 111A to 111C, 112A to 112C, 113A to 113C, 114A to 114C, and 115A to 115C.
The image control program ROM 84 stores an image control program and various types of selection tables relating to display on the upper display portion 3A and the variably display portion 3B. The image control work RAM 83 functions as a temporary memory to be used in execution of the image control program in the image control CPU 82. The image control IC 88 forms an image in accordance with the contents determined by the image control CPU 82 and then outputs the image thus formed to the upper display portion 3A and the variably display portion 3B.
The image ROM 86 stores dot data for forming an image. The video RAM 87 functions as a temporary memory to be used by the image control IC 88 in forming an image.
Here, the internal construction of the slot machine 1 as mentioned above is merely one example and one or more aspects of the invention is not so limited. For example, memory card and/or PLD (Programmable Logic Device) may be detachably from the slot machine 1 and necessary information may be read from the memory card and/or the PLD.
The slot machine 1 of the first embodiment employs coins, bills or electronic value information (credit) corresponding to these, as gaming values. The gaming values applicable to the present invention are not limited to those described above, and can include, for instance, medals, tokens, electronic money and tickets.
Next, the symbols which are variably displayed on the symbols display portion will be described with reference to
As shown in
Symbols shown in
Next, a base game and a free game executed on the slot machine 1 having the above configuration will be described. In the base game, all of the symbols are scatter symbol. The base game is a game in which an award is provided based on the number of same symbols displayed on the symbol display portions 111A to 111C, 112A to 112C, 113A to 113C, 114A to 114C, and 115A to 115C with 3×5 matrix (namely, matrix in 3 rows and 5 columns) shape on the variably display portion 3B.
When the bet count is determined based on the operation of the bet button, and then the start button is input, the reels start to spin on the each of the reel display portions 101 to 105. Accordingly, the symbol rows displayed on the reel are scrolled from top to bottom, as shown in
In the base game, winning combination is determined based on the number of the same symbols and an award corresponding to the determined winning combination will be provided. If the winning combination is realized, amount of outcome, which the payout number corresponding to the winning combination is multiplied by the bet number, is provided to the player. This point will be described later.
On the other hand, the free game is a game which is switched-executed from the base game if the predetermined condition is met in the base game. Here, the predetermined condition can be a condition where the BONUS symbols 45G (predetermined symbol) are displayed with a predetermined number (for example, three) and above.
The free games are executed with the predetermined number (for example, ten). After the free game is terminated, the game is changed to the base game again. Here, with respect to the procedure of the free game, the free game is the same as the base game, except that in the free game, gaming values (credits) corresponding to the bet amount are not consumed at the start of the game, and the game is continuously carried out automatically without requiring the player to operate the operation button. Here, the number of the executed free game is variable. Also, one or more aspects of the invention may have different types of the number of the free game to be executed, and the number of the free game to be executed can be selected based on a predetermined condition.
The winning combination and payout number thereof used in the base game and the free game in the slot machine 1 of the embodiment will be described with reference to
For example, if twelve “A” symbols are displayed on the symbol display portions 111A to 111C, 112A to 112C, 113A to 113C, 114A to 114C, and 115A to 115C, amount of outcome which 60 credit is multiplied by the bet number will be provided to the player.

Next, a main control program executed in the slot machine 1 of the embodiment will be described in detail with reference to drawings.
First, when the power switch is turned on (upon power on), the main control board 71 and the sub-control board 72 are activated, and the controller 41 executes an initial setting process at step (hereinafter referred to as S) 1. In the initial setting process, the main CPU 42 executes the BIOS stored in the ROM 44 and expands the compressed data incorporated in the BIOS in the RAM 43. By executing the BIOS that was expanded in the RAM 43, the main CPU 42 carries out a diagnosis and initialization of the different types of peripheral devices. Further, the main CPU 42 writes the game programs and the like from the ROM 44 into the RAM 43 to acquire payout rate setting data and country identification information. While executing the initial setting process, the main CPU 42 also carries out an authentication process with respect to each program.
Then, at step S2, the main CPU 42 sequentially reads the game programs and the like from the RAM 43 and executes these programs to carry out a main game process. The slot machine 1 according to the embodiment carries out the game by executing this main game process. The main game process is repeatedly executed while power is supplied to the slot machine 1.
Next, a sub-process of the main game process at the above-described step S2 will be described based on
As shown in
At S12, the main CPU 42 determines whether or not the start button from amongst the operation buttons 26 has been depressed. This determination is carried out based on the signal inputted to the main CPU 42 in response to depression of the start button. Here, if the start button has not been depressed (S12: NO), the flow returns to the start acceptance process (S11). As a result, the player can carry out an operation to correct, etc. the bet amount. Alternatively, if the start button has been depressed (S12: YES), the main CPU 42 subtracts the bet amount set based on the above-described bet operation from the credit amount that the player currently possesses and at the same time stores the result as bet information in the RAM 43. After that, the procedure will be shifted to S13.
In S13, the symbol lottery process is executed. Concretely, the main CPU 42 samples random number value from a number value range within a predetermined random number value range by executing the lottery program store in the RAM 43, and determines symbols to be stopped on center positions of each reel display portion 101 to 105 (namely, symbol display portion 111B, 112B, 113B, 114B, and 115B) based on the sampled random number values and the table.
Here, a process using random number values in S13 will be described.
Here, as shown in
For example, with respect to the reel display portion 101, in a case where reel shown in

Also, as shown in
Returning to
For example, the MEAT symbol 45B determined in S13 is stopped on the symbol display portion 111B. In this case, the BONUS symbol 45G is displayed on the symbol display portion 111A and the MEAT symbol 45B is displayed on the symbol display portion 111C.
After that, in S15, the main CPU 42 determines whether or not the symbols arranged on the variably display portion 3B correspond the winning combination. This determination is performed based on the code numbers of each reel display portion 101 to 105 stored in the RAM 43.
At a result, if it is determined that the winning combination is realized (S15:YES), the procedure will be shifted to S16. On the other hand, if it is determined that none of the winning combinations is not realized (S15:NO), the procedure will be shifted to S17. Here, if a game will be ongoingly started in next time, the process of S13 and later will be executed again.
In S16, the main CPU 42 provides the payout number corresponding to the winning combination which is determined in S15 to the player.
Next, in S17, the main CPU 42 determines whether or not a free game start trigger is realized. As mentioned above, a condition of shifting the free game may be displaying of the bonus symbol or displaying of the predetermined symbol with the predetermined number.
If it is determined that the free game start trigger is realized (S17:YES), the procedure will be shifted to a free game process (S18), and the game is changed from the base game to the free game. Here, detail of the free game process will be described later. On the other hand, if it is determined that the free game start trigger is not realized (S17:NO), the procedure will be terminated.
Next, the free game will be described with reference to
In S24, the payout number is determined based on the displayed symbols and determined payout number is accumulated. The accumulated payout number in this process will be provided to the player in S26 which will be described later.
In S25, it is determined whether or not the free game is executed with a predetermined number. If it is determined that the free game is executed with the predetermined number (S25:YES), the procedure will be shifted to S26. On the other hand, if it is determined that the free game is not executed with the predetermined number (S25:NO), the procedure will be returned to S21.
In S26, accumulated payout number is provided to the player. Here, the process as described above, when the free game is executed with the predetermined number, accumulated payout number is provided at once, the payout number may be provided every the free game.
In the display change process for the second specific symbol as mentioned above, symbol display portions, on which the first specific symbol and the second specific symbol are displayed, can be combined to one display area and predetermined image can be displayed on the combined display area, before the second specific symbol is changed.
With respect to the process in which the second specific symbol changes into the first specific symbol, a concrete example of a process using an alignment of symbols will be described.
An example of the symbol change process will be described with reference to
In S31, it is determined whether or not determination target symbol is the first specific symbol.
If it is determined that the determination target symbol is the first specific symbol (S31:YES), the procedure will be shifted to S32.
In S32, the position of the symbol which is adjacent is stored in the RAM 43.
In S33, it is determined whether or not all of displayed symbols are processed. If it is determined that all of the displayed symbols are processed (S33:YES), the procedure will be shifted to S34 and the symbol displayed on the stored position in the RAM 43 is changed to the first specific symbol. On the other hand, it is determined that the symbol which is not the determination target exists (S33:NO), the procedure will be returned to S31 and the above process is executed again.
In above process, determination process, which determines whether or not the first specific symbol and the second specific symbol are adjacently displayed, can be simplified with the use of the alignment of symbols as mentioned above. That is, it can be determined whether or not the second specific symbol is adjacently displayed based on whether the first specific symbol is displayed on the symbol display portion. Also, in the above example, since three symbols are displayed on each of the reel display portion, above process is implemented by that at least two second specific symbols are consecutively adjacently displayed respectively on both sides (upper side and under side) of the first specific symbol. Here, in one or more aspects of the invention which N of the first specific symbols are displayed on the symbol display portions, above process is implemented by that at least “N-1” of the second specific symbols are consecutively adjacently displayed respectively on up both sides of the first specific symbol.
In one or more aspects of the invention, it can be determined whether or not the first specific symbol and the second specific symbol are adjacently displayed with the use of tables.

As mentioned above, in the slot machine 1 of the first embodiment, if the predetermined condition is met (S17:YES) and the free game is started, reels are variably displayed on the reel display portions 101 to 105, and symbols are displayed on the variably display portions after the predetermined time is elapsed (S22). Then, if the LION symbol 45A and the MEAT symbol 45B are adjacently displayed (S31:YES), the MEAT symbol is changed to the LION symbol 45A (S34). Therefore, as shown in
Also, since the processes use the alignment of the symbols, one or more aspects of the invention can reduce processing load. Also, since the processes use the tables stored in the memory, one or more aspects of the invention can be implemented by software and hardware resources which are cooperatively working.
Next, a second embodiment embodying one or more aspects of the invention will be described. Hereinafter, reference numbers, which are the same as the slot machine 1 shown in
A schematic configuration of a slot machine 1 according to the second embodiment is substantially same as the slot machine 1 according to the first embodiment. Also, each control processes in the second embodiment is substantially the same as the processes in the first embodiment.
In the slot machine 1 in the first embodiment, the symbol change process is executed in the only the free game, however, in the second embodiment, the symbol change process is executed in the base game.
A sub process of the main game process executed in the slot machine according to the second embodiment will be described with reference to
In the second embodiment, the symbol replacement process executed on the displayed symbols in the reel spin control process.
Since processes in S61 to S64 shown in
As mentioned above, in the slot machine 1 according to the second embodiment, if the base game is started, the reels are variably displayed on the reel display portions 101 to 105, and symbols are displayed on the variably display portion 3B after the predetermined time is elapsed (S64). Then, if the LION symbol 45A and the MEAT symbol 45B are adjacently displayed (S31:YES), the MEAT symbol is changed to the LION symbol 45A (S34). Therefore, as shown in
The present invention is not limited to above embodiments and various changes and modifications can be done within the scope of the present invention certainly. For example, in a case where one or more aspects of the invention are implemented by the hybrid type slot machine which has the mechanical reels and transparent liquid crystal display device, the mechanical reels can be used in the base game and video reels displayed on the transparent liquid crystal display device can be used in the free game. Also, in the same game, some reel can be implemented by the mechanical reel and other reel can be implemented by the video reel. Further, one or more aspects of the invention can be different type of the reels and reel can be selected based on the payout ratio.
Also, one or more aspects of the invention can be implemented as a playing method to execute above processes. Further, one ore more aspects of the invention can be implemented as a program to execute above processes in one or more computers, and a tangible medium in which the program is stored.
