1. Field of the Invention
The present invention relates to a slot machine having special symbols 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 a payouts based on such scatter symbols, there is no relationship between payouts and positions at which the scatter symbols are displayed.
In such conventional slot machines, symbols to be stop-displayed (rearranged) typically have a predetermined picture (e.g. watermelon, cherry, number “7”, etc.). However, since only similar symbols are used in a large number of slot machines, there have been cases where a player is unlikely to feel freshness. This has caused a problem of making the player soon bored of a game.
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 having special symbols that have a player feel freshness.
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 and U.S. 2002-0065124-A1 are incorporated herein by reference in their entirety.
The present invention provides a slot machine comprising the following configuration.
Namely, the aforementioned slot machine comprises a display capable of rearranging synthetic symbol images each including a first symbol image associated with a predetermined prize and a second symbol image different from the first symbol images; a memory capable of storing first symbol image data indicating the first symbol image, second symbol image data indicating the second symbol image, and special first symbol image data indicating a special first symbol image corresponding to the first symbol image; and a controller programmed so as to execute the processing of: (A) rearranging the synthetic symbol images to the display based upon the first symbol image data and the second symbol image data stored in the memory, and (B) displaying the special first symbol images corresponding to first symbol images which are included in the synthetic symbol images rearranged in the processing (A) and constitute the predetermined prize, to the display based upon the special first symbol image data stored in the memory in place of the synthetic symbol images including the first symbol images out of the synthetic symbol images rearranged in the processing (A) in a case where the first symbol images included in the synthetic symbol images rearranged in the processing (A) or a combination thereof constitute the predetermined prize.
According to the aforementioned slot machine, the synthetic symbol images each including the first symbol image and the second symbol image are rearranged to the display. Such symbol images formed by synthesizing the two kinds of symbol images are not usually displayed in slot machines, and a player is unfamiliar with such symbol images. Therefore, by showing the player such symbol images, it is possible to have the player feel freshness. This can result in provision of a game in which the player is unlikely to become bored.
Further, according to the aforementioned slot machine, the first symbol image is associated with the predetermined prize. When the first symbol images included in the rearranged synthetic symbol images or a combination thereof constitute the predetermined prize (e.g. when a predetermined winning combination is established along a winning line), the special first symbol images are displayed to the display in place of the synthetic symbol images (the synthetic symbol images rearranged along the winning line) including the first symbol images that constitute the predetermined prize. The special first symbol images correspond to the first symbol images that constitute the predetermined prize.
Thereby, when the first symbol images included in the rearranged synthetic symbol images constitute the predetermined prize, the first symbol images can be displayed to the display with substantially the same sizes as those of the synthetic symbol images. It is therefore possible to give the player an impression as if the first symbol images constituting the predetermined prize have expanded to the special first symbol images as triggered by establishment of the prize. Hence it becomes possible to have the player feel interested in a view being as if the first symbol images expand to the special first symbol images, so as to make the player absorbed in the game.
Moreover, since the special first symbol images corresponding to the predetermined prize are displayed with sizes larger than those of the first symbol images and the second symbol images in the case of establishment of the predetermined prize, it is possible to make the player immediately aware of which prize has been established. This enables provision of a game very easy to understand for the player.
Further the slot machine of the present invention preferably has the following configuration.
Namely, the special first symbol image is an image having a substantially same picture as a picture of the corresponding first symbol image.
According to the aforementioned slot machine, the picture of the first symbol image is the substantially same as the picture of the special first symbol image corresponding to the first symbol image. It is thereby possible to further strengthen the impression received by the player as if the first symbol images constituting the predetermined prize have expanded to the special first symbol images as triggered by establishment of the prize. Hence it becomes possible to have the player feel increasingly interested in the view being as if the first symbol images expand to the special first symbol images, so as to make the player further absorbed in the game.
Further the slot machine of the present invention preferably has the following configuration.
Namely, the second symbol image is associated with a special prize different from the predetermined prize. Further, the memory is capable of storing special second symbol image data indicating a special second symbol image corresponding to the second symbol image. Furthermore, the controller is further programmed so as to execute processing of (C) displaying the special second symbol images corresponding to second symbol images which are included in the synthetic symbol images rearranged in the processing (A) and constitute the special prize, to the display based upon the special second symbol image data stored in the memory in place of the synthetic symbol images including the second symbol images out of the synthetic symbol images rearranged in the processing (A) in a case where the second symbol images included in the synthetic symbol images rearranged in the processing (A) or a combination thereof constitute the special prize.
According to the aforementioned slot machine, the second symbol image is associated with the special prize different from the aforementioned predetermined prize. Namely, the two kinds of symbol images constituting the synthetic symbol image are both associated with prizes. For example, the first symbol image is associated with a normal prize, and the second symbol image is associated with a bonus. It is thereby possible to make the player pay attention to both the first symbol images and the second symbol images. Consequently, it is possible to make the player further absorbed in the game.
Moreover, according to the aforementioned slot machine, when the second symbol images included in the rearranged synthetic symbol images or a combination thereof constitute the special prize (e.g. when a predetermined winning combination is established along the winning line), the special second symbol images are displayed to the display in place of the synthetic symbol images (the synthetic symbol images rearranged along the winning line) including the second symbol images that constitute the special prize. The special second symbol images correspond to the second symbol images that constitute the special prize.
Namely, it is possible to display to the display the special first symbol images with substantially the same sizes as those of the synthetic symbol images in the case of establishment of the predetermined prize by the first symbol images, while displaying to the display the special second symbol images with substantially the same sizes as those of the synthetic symbol images in the case of establishment of the special prize by the second symbol images. It is therefore possible to give the player an impression as if the first symbol images constituting the predetermined prize have expanded to the special first symbol images in the case of establishment of the predetermined prize by the first symbol images, while giving the player an impression as if the second symbol images constituting the special prize have expanded to the special second symbol images in the case of establishment of the special prize.
As thus described, it is possible to show the player a view being as if the first symbol images expand to the special first symbol images or a view being as if the second symbol images expand to the special second symbol images, depending upon whether the predetermined prize is established or the special prize is established. It is thus possible to have the player feel increasingly interested in such unfamiliar views.
The present invention provides a slot machine having the following configuration.
Namely, the aforementioned slot machine comprises a symbol display capable of variably displaying synthetic symbols each including a first symbol associated with a predetermined prize and a second symbol different from the first symbols; a display which is capable of displaying special first symbol images corresponding to the first symbols and arranged at a front face of the symbol display, a memory capable of storing special first symbol image data indicating the special first symbol image; and a controller programmed so as to execute the processing of: (A) variably displaying and then stop-displaying a plurality of the synthetic symbols to the symbol display, and (B) displaying the special first symbol images corresponding to first symbols which are included in the synthetic symbols stop-displayed in the processing (A) and constitute the predetermined prize, to the display based upon the special first symbol image data stored in the memory in such a manner as to cover the synthetic symbols including the first symbols in a case where the first symbols or a combination thereof constitute the predetermined prize.
According to the aforementioned slot machine, the synthetic symbols each including the first symbol and the second symbol are stop-displayed to the symbol display. Such symbols formed by synthesizing the two kinds of symbols are not usually displayed in slot machines, and a player is unfamiliar with such symbols. Therefore, by showing the player such symbols, it is possible to have the player feel freshness. This can result in provision of a game in which the player is unlikely to become bored.
Further, according to the aforementioned slot machine, the first symbol is associated with the predetermined prize. When the first symbols included in the stop-displayed synthetic symbols or a combination thereof constitute the predetermined prize (e.g. when a predetermined winning combination is established along a winning line), the special first symbol images are displayed to the display in place of the synthetic symbols (the synthetic symbols stop-displayed along the winning line) including the first symbols that constitute the predetermined prize. The special first symbol images correspond to the first symbols that constitute the predetermined prize.
Thereby, when seen from the player, the synthetic symbols each including the first symbol that constitutes the predetermined prize are hidden by the special first symbol images. It is therefore possible to give the player an impression as if the first symbols constituting the predetermined prize have expanded to the special first symbol images as triggered by establishment of the prize. Hence it becomes possible to have the player feel interested in a view being as if the first symbols expand to the special first symbol images, so as to make the player absorbed in the game.
Moreover, since the special first symbol images corresponding to the predetermined prize are displayed with sizes larger than those of the first symbols and the second symbols in the case of establishment of the predetermined prize, it is possible to make the player immediately aware of which prize has been established. This enables provision of a game very easy to understand for the player.
Further the slot machine of the present invention preferably has the following configuration.
Namely, the second symbol is associated with a special prize different from the predetermined prize. The memory is capable of storing special second symbol image data indicating special second symbol image corresponding to the second symbol image. The controller is further programmed so as to execute processing of (C) displaying the special second symbol images correspond to second symbols which are included in the synthetic symbol images stop-displayed in the processing (A) and constitute the special prize, to the display based upon the special second symbol image data stored in the memory in such a manner as to cover the synthetic symbols including the second symbols in a case where the second symbols or a combination thereof constitute the special prize.
According to the aforementioned slot machine, the second symbol is associated the special prize different from the aforementioned predetermined prize. Namely, the two kinds of symbols constituting the synthetic symbol are both associated with prizes. For example, the first symbol is associated with a normal prize, and the second symbol is associated with a bonus. It is thereby possible to make the player pay attention to both the first symbols and the second symbols. Consequently, it is possible to make the player further absorbed in the game.
Moreover, according to the aforementioned slot machine, when the second symbols included in the stop-displayed synthetic symbols or a combination thereof constitute the special prize (e.g. when a predetermined winning combination is established along the winning line), the special second symbols are displayed to the display in such a manner as to cover the synthetic symbols (the synthetic symbols rearranged along the winning line) including the second symbols that constitute the special prize. The special second symbols correspond to the second symbols that constitute the special prize.
Namely, it is possible to display to the display the special first symbols in such a manner as to cover the synthetic symbols in the case of establishment of the predetermined prize by the first symbols, while displaying to the display the special second symbol images in such a manner as to cover the synthetic symbols in the case of establishment of the special prize by the second symbols. It is therefore possible to give the player an impression as if the first symbols constituting the predetermined prize have expanded to the special first symbol images in the case of establishment of the predetermined prize by the first symbol images, while giving the player an impression as if the second symbols constituting the special prize have expanded to the special second symbol images in the case of establishment of the special prize.
As thus described, it is possible to show the player a view being as if the first symbols expand to the special first symbol images or a view being as if the second symbols expand to the special second symbol images, depending upon whether the predetermined prize is established or the special prize is established. It is thus possible to have the player feel increasingly interested in such unfamiliar views.
The present invention provides a slot machine having the following configuration.
Namely, the aforementioned slot machine comprises a symbol display capable of variably displaying a plurality of second symbols; a display which is arranged at a front face of the symbol display and capable of rearranging first symbol images each associated with a predetermined prize and displayed in such a manner as to partially cover the second symbol; a memory capable of storing first symbol image data indicating the first symbol image and special first symbol image data indicating special first symbol images corresponding to the first symbol image; and a controller programmed so as to execute the processing of: (A) variably displaying and then stop-displaying the plurality of second symbols to the symbol display, (B) rearranging to the display the first symbol images each displayed in such a manner as to partially cover the second symbol stop-displayed in the processing (A) based upon the first symbol image data stored in the memory, and (C) displaying the special first symbol images corresponding to the first symbol images which are rearranged in the processing (B) and constitute the predetermined prize, to the display based upon the special first symbol image data stored in the memory in such a manner as to cover substantially the whole of second symbols partially covered by the first symbol images out of the second symbols stop-displayed in the processing (A) in a case where the first symbol images or a combination thereof constitute the predetermined prize.
According to the aforementioned slot machine, the second symbols are stop-displayed to the symbol display. Further, the first symbol images associated with the predetermined prize are rearranged to the display in such a manner as to partially cover the second symbols stop-displayed to the symbol display. Therefore, it appears to the player that the synthetic symbols each including the first symbol image and the partially covered second symbol image are displayed. Such symbols formed by synthesizing the two kinds of symbols are not usually displayed in slot machines, and a player is unfamiliar with such views. Therefore, by showing the player such symbols, it is possible to have the player feel freshness. This can result in provision of a game in which the player is unlikely to become bored.
Further, according to the aforementioned slot machine, the first symbol image is associated with the predetermined prize. When the rearranged first symbol images or a combination thereof constitute the predetermined prize (e.g. when a predetermined winning combination is established along the winning line), the special first symbol images are displayed to the display in such a manner as to cover substantially the whole of the second symbols partially covered by the first symbol images constituting the predetermined prize. The special first symbol images correspond to the first symbol images that constitute the predetermined prize.
Thereby, when seen from the player, the whole of the second symbols partially covered by the first symbol images that constitute the predetermined prize are hidden by the special first symbol images. It is therefore possible to give the player an impression as if the first symbol images constituting the predetermined prize have expanded to the special first symbol images as triggered by establishment of the prize. Hence it becomes possible to have the player feel interested in a view being as if the first symbol images expand to the special first symbol images, so as to make the player absorbed in the game.

The lamp 30 lights up in a predetermined pattern based on a control signal outputted from the main CPU 41.
The hopper 66 is installed inside the cabinet 11 and pays out a predetermined number of coins from the coin payout exit 19 to the coin tray 18, based on a control signal outputted from the main CPU 41. The coin detecting portion 67 is provided inside the coin payout exit 19, and outputs an input signal to the main CPU 41 when detecting a payout of a predetermined number of coins from the coin payout exit 19.
The graphic board 68 controls, based on a control signal outputted from the main CPU 41, an image display to the upper image display panel 33 and the lower image display panel 16. The number of credits stored in RAM 43 is displayed to the number-of-credits display section 31 (not shown) of the lower image display panel 16. The number of coins-out is displayed to the number-of-payouts display section 32 (not shown) of the lower image display panel 16. The graphic board 68 is equipped with VDP (Video Display Processor) which generates image data based on a control signal outputted from the main CPU 41 and a video RAM which temporarily stores image data generated by VDP, and of the like equipments. It should be noted that image data used in generating image data with VDP is contained in a game program read from the memory card 53 and stored in RAM 43.
The bill validator 22 not only discriminates a regular bill from a false bill, but also accepts the regular bill into the cabinet 11. When accepting a regular bill, the bill validator 22 outputs an input signal to the main CPU 41, based on the face amount of the bill. The main CPU 41 stores, in the RAM 43, the number of credits according to the face amount of the bill transmitted with the input signal.
The ticket printer 35 prints on a ticket, based on a control signal outputted from the main CPU 41, a barcode formed by encoding data such as the number of credits, date and time, an identification number of the slot machine 10, and of the like data stored in the RAM 43, and outputs the ticket as a ticket 39 with a barcode.
The card reader 36 reads data from a smart card and transmits the data to the main CPU 41 or writes data into the smart card based on a control signal from the main CPU 41. The key switch 38S is provided on the keypad 38, and outputs a predetermined input signal to the main CPU 41 when the keypad 38 is operated by the player. The data display 37 displays, based on a control signal outputted from the main CPU 41, data read by the card reader 36 or data inputted by the player through the keypad 38.
To the door PCB 80, there are connected a control panel 20, a reverter 21S, a coin counter 21C, and a cold cathode tube 81. The control panel 20 is provided with a start switch 23S corresponding to the start button 23, a change switch 24S corresponding to the change button 24, a CASHOUT switch 25S corresponding to the CASHOUT button 25, a 1-BET switch 26S corresponding to the 1-BET button 26, and a maximum BET switch 27S corresponding to the maximum BET button 27. Each of the switches 23S to 27S outputs an input signal to the main CPU 41 when each of the buttons 23 to 27 corresponding thereto is operated by the player.
The coin counter 210 is provided inside the coin receiving slot 21 and discriminates a regular coin from a false coin inserted into the coin receiving slot 21 by the player. Coins other than regular coins are discharged from the coin payout exit 19. When the coin counter 21C detects a regular coin, the coin counter 21C outputs an input signal to the main CPU 41.
The reverter 21S operates based on a control signal outputted from the main CPU 41, and distributes a coin identified by the coin counter 21C as a regular coin into a cash box (not shown) or the hopper 66, which are disposed in the slot machine 10. 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.
First, in the slot machine 10, activation processing is executed (step S101). The activation processing will be specifically described later by using
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 execute slot machine game execution processing (step S102). The slot machine game execution processing will be described in more detail later using
Hereinafter, slot machine game execution processing executed in the slot machine 10 will be described.
The main CPU 41 reads a game program and executes the game program to progress a slot machine game.
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 (10 in the first 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 rearranges the normal payout symbol images (small) and the bonus payout symbol images (small) in the first display region 103A to the fourth display region 103D of the symbol matrix SM (step S14).
In the processing, first, the main CPU 41 starts scroll display of symbol images (normal payout symbol images (small) and bonus payout symbol images (small)) in the first display region 103A to the fifth display region 103E. The main CPU 41 executes the aforementioned symbol selection program, and determines the symbol images (the normal payout symbol images (small) and the bonus payout symbol images (small)) to be rearranged in the first display region 103A to the fifth display region 103E of the symbol matrix SM. The main CPU 41 then rearranges the symbol images (the normal payout symbol images (small) and the bonus payout symbol images (small)) in the normal payout symbol image (small) display regions and the bonus game payout symbol image (small) display regions.
Next, the main CPU 41 determines whether or not the game is in a ready-to-win state for establishment of the jackpot trigger, the free game trigger or the bonus game trigger (step S15). Namely, the main CPU 41 determines whether or not four of at least one kind of bonus payout symbol images (small) out of the jackpot trigger symbol images (small), the free game trigger symbol images (small) and the bonus game trigger symbol images have been rearranged along a line in the bonus payout symbol image (small) display regions of the first display region 103A to the fourth display region 103D.
When determining that the game is in a ready-to win state for establishment of the jackpot trigger, the free game trigger or the bonus game trigger, the main CPU 41 performs the following processing in step S16.
Namely, when four bonus game trigger symbol images (small) are displayed along a line on any row in the bonus payout symbol image (small) display regions of the first display region 103A to the fourth display region 103D, the main CPU 41 completes display of the symbol images ((i) and (ii) described below) on the row.
(i) four bonus game trigger symbol images (small) rearranged along a line
(ii) normal payout symbol images (small) included in synthetic symbol images including the aforementioned bonus game trigger symbol image (small) of (i), namely normal payout symbol image (small) constituting synthetic symbol images together with the bonus game trigger symbol images (small), that is, normal payout symbol images (small) rearranged on the same row as the row where the bonus game trigger symbol images (small) are displayed
The main CPU 41 then displays bonus game trigger symbol images (large) in the synthetic symbol image display regions of the first display region 103A to the fourth display region 103D on the row where the aforementioned bonus game trigger symbol images (small) of (i) and the aforementioned normal payout symbol images (small) of (ii) have been displayed (cf.
Since processing executed by the main CPU 41 in step S16 in a case where four jackpot trigger symbol images (small) are rearranged along a line or four free game trigger symbol images are rearranged along a line is substantially similar to the above-mentioned processing, the descriptions thereof are omitted here.
When determining in step S15 that the game is not in a ready-to-win state for establishment of any of the jackpot trigger, the free game trigger and the bonus game trigger, or after executing the processing of step S16, the main CPU 41 shifts the processing to step S17.
In step S17, the main CPU 41 rearranges symbol images (the normal payout symbol images (small) and the bonus payout symbol images (small)) in the normal payout symbol image (small) display region and the bonus payout symbol image (small) display region of the fifth display region 103E.
Next, the main CPU 41 determines whether or not the jackpot trigger has been established (step S20).
When determining that the jackpot trigger has been established, the main CPU 41 determines whether or not the winning combination has been established on the same row as the row where the jackpot trigger has been established. In the processing, the main CPU 41 determines whether or not five normal payout symbol images (small) have been rearranged along the row where five jackpot trigger symbol images (small) in accordance with establishment of the jackpot trigger have been rearranged along a line.
When determining that the winning combination has not been established on the same row as the row where the jackpot trigger has been established, the main CPU 41 performs the following processing in step S22.
Namely, the main CPU 41 completes display of symbol images ((i) to (iii) described below) on the row where the jackpot trigger has been established.
(i) jackpot trigger symbol images (large) displayed in the first display region 103A to the fourth display region 103D
(ii) a jackpot trigger symbol image (small) in accordance with establishment of the jackpot trigger out of bonus payout symbol images (small) rearranged along the fifth display region 103E
(iii) a normal payout symbol image (small) included in synthetic symbol images including the aforementioned jackpot trigger symbol image (small) of (ii), namely a normal payout symbol image (small) constituting a synthetic symbol image together with the jackpot trigger symbol image (small), that is, a normal payout symbol image (small) rearranged along the same row as the row where the jackpot trigger symbol image (small) is displayed
The main CPU 41 then displays jackpot trigger establishment symbol images in the synthetic symbol image display regions of the first display region 103A to the fifth display region 103E on the row where the aforementioned jackpot trigger symbol images (large) of (i), the aforementioned jackpot trigger symbol image (small) of (ii) and the aforementioned normal payout symbol image (small) of (iii) have been displayed.
Next, the main CPU 41 conducts a payout based upon the progressive jackpot (step S23). The number of coins to be paid out in the progressive jackpot corresponds to a value obtained by adding an initial payout value to an accumulated value (a value resulted from accumulation of a portion of the number of inserted game media) stored in the RAM 43, and the payout is conducted through hand-pay. Examples of the processing executed by the main CPU 41 in the step S23 may include outputting a notification sound from the speaker 29, lighting the lamp 30, printing the ticket 39 with a barcode indicating the number of payout printed thereon, and the like.
Since the slot machine 10 is a stand-alone type slot machine, the value obtained by adding the initial payout value to the accumulated value (the value resulted from accumulation of a portion of the number of inserted game media) of the slot machine 10 is adopted as a payout in the progressive jackpot.
However, in the present invention, the accumulated value adopted to the progressive jackpot is not limited to this example. For example, when the slot machine is connected to a network, it is possible to adopt an accumulated value of the same kind of slot machines inside a single casino, an accumulated value of the same kind of slot machine in the same region (e.g. a state or a country), and the like can be adopted.
When the winning combination is established on the same row as the row where the jackpot trigger has been established in step S21, the main CPU 41 executes the following processing.
Namely, the main CPU 41 completes display of symbol images ((i) to (iii) described below) on the row where the jackpot trigger has been established.
(i) jackpot trigger symbol images (large) displayed in the first display region 103A to the fourth display region 103D
(ii) a jackpot trigger symbol image (small) in accordance with establishment of jackpot trigger out of bonus payout symbol images (small) rearranged along the fifth display region 103E
(iii) a normal payout symbol image (small) included in synthetic symbol images including the aforementioned jackpot trigger symbol image (small) of (ii), namely a normal payout symbol image (small) constituting a synthetic symbol images together with the jackpot trigger symbol image (small), that is, normal payout symbol images (small) rearranged on the same row as the row where the jackpot trigger symbol image (small) is displayed.
The main CPU 41 then displays double payout symbol images in the synthetic symbol image display regions of the first display region 103A to the fifth display region 103E on the row where the aforementioned jackpot trigger symbol images (large) of (i), the aforementioned jackpot trigger symbol image (small) of (ii) and the aforementioned normal payout symbol images (small) of (iii) have been displayed.
Next, the main CPU 41 conducts a payout based upon establishment of the winning combination while conducting a payout based upon the progressive jackpot (step S25).
The payout based upon the progressive jackpot is as described in step S23. The payout based upon establishment of the winning combination will be described in step S32.
When determining in step S20 that the jackpot trigger has not been established or after executing the processing of step S23 or step S25, the main CPU 41 determines whether or not the winning combination has been established (step S30). In the processing, the main CPU 41 determines whether or not five normal payout symbol images (small) have been rearranged on any row of the symbol matrix SM.
When determining that the winning combination has been established, the main CPU 41 executes the following processing in step S31.
Namely, the main CPU 41 completes display of the symbol images ((i) to (ii) described below) on the row where the winning combination has been established.
(i) five normal payout symbol images (small) constituting the winning combination
(ii) bonus payout symbol images (small) included in synthetic symbol images including the aforementioned normal payout symbol images (small) of (i), namely bonus payout symbol images (small) constituting synthetic symbol images together with the normal payout symbol images (small), that is, bonus payout symbol images (small) rearranged on the same row as the row where the normal payout symbol images (small) are displayed.
The main CPU 41 then displays normal payout symbol images (large) in the synthetic symbol image display regions of the first display region 103A to the fifth display region 103E on the row where the aforementioned normal payout symbol images (small) of (i) and the aforementioned bonus payout symbol images (small) of (ii) have been displayed (cf.
Next, the main CPU 41 pays out coins based upon odds (normal odds) in the normal game (step S32).
For example, when five coins are BET, the number of coins to be paid out in the case of establishment of “AIR PLANE×5” is 20×5=100 coins (cf.
In the case of storing coins, the main CPU 41 executes the processing of addition of the number of credits stored in the RAM 43. On the other hand, in the case where coins are to be paid out, the main CPU 41 transmits a control signal to the hopper 66, to pay out a predetermined number of coins.
When determining in step S30 that the winning combination has not been established, or after executing the processing of step S32, the main CPU 41 determines whether or not the bonus game trigger has been established (step S40).
When determining that the bonus game trigger has been established, the main CPU 41 determines whether or not the free game trigger has been established (step S41).
When determining that the free game trigger has not been established, the main CPU 41 executes the following processing in step S42.
Namely, the main CPU 41 completes display of symbol images ((i) to (iii) described below or (I) described below) on the row where the bonus game trigger has been established.
(i) bonus game trigger symbol images (large) displayed in the first display region 103A to the fourth display region 103D
(ii) bonus game trigger symbol images (small) in accordance with establishment of the bonus game trigger out of bonus payout symbol images (small) rearranged along the fifth display region 103E
(iii) a normal payout symbol images (small) included in synthetic symbol images including the aforementioned bonus game trigger symbol image (small) of (ii), namely a normal payout symbol images (small) constituting a synthetic symbol image together with the bonus game trigger symbol image (small), that is, a normal payout symbol images (small) rearranged on the same row as the row where the bonus game trigger symbol image (small) is displayed
(I) normal payout symbol images (large) displayed in the first display region 103A to the fifth display region 103E.
The main CPU 41 then displays bonus game trigger establishment symbol images (cf.
Next, the main CPU 41 executes bonus game execution processing (step S43). The bonus game execution processing will be described later using
When determining in step S41 that the free game trigger has been established, the main CPU 41 executes the following processing in step S44.
Namely, the main CPU 41 completes display of the symbol images ((i) to (iii) described below or (I) described below) on the row where the bonus game trigger has been established, and display of the symbol images ((iv) to (vi) described below or (II) described below) on the row where the free game trigger has been established.

Next, the main CPU 41 determines whether or not TF is 0 (step S261).
When determining that TF is not 0, the main CPU 41 returns the processing to step S213. On the other hand, when determining that TF is 0, the main CPU 41 completes the present subroutine.
First, the main CPU 41 sets the remaining number TS of special bonus games to TS=CS (CS=10 in the first embodiment) in a number-of-special-bonus-game storage area of the RAM 43 (step S310).
Subsequently, the main CPU 41 executes processing of steps S313 to S317, steps S320 to S325, steps S330 to 332, steps S340 to S345, and steps S350 to S352. However, the processing is substantially same as the processing of steps S13 to S17 of

Subsequently, there will be described activation processing (see step S101 in
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
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 executes insurance setting processing and game execution 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.
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.
According to the slot machine 10 of the first embodiment, the synthetic symbol images each including the normal payout symbol image (small) and the bonus payout symbol image (small) are rearranged in the symbol matrix (SM). Such symbol images formed by synthesizing the two kinds of symbol images are not usually displayed in slot machines, and a player is unfamiliar with such symbol images. Therefore, by showing the player such symbol images, it is possible to have the player feel freshness. This can result in provision of a game in which the player is unlikely to become bored.
Further, according to the slot machine 10 of the first embodiment, the normal payout symbol image (small) is associated with the winning combination. When the normal payout symbol images (small) included in the rearranged synthetic symbol images or a combination thereof constitute the winning combination, the normal payout symbol images (large) are displayed to the symbol matrix (SM) in place of the synthetic symbol images (the synthetic symbol images rearranged along the winning line) including the normal payout symbol images that constitute the winning combination. The normal payout symbol image (large) has substantially the same picture as that of the normal payout symbol image (small) that constitute the winning combination.
Thereby, when the normal payout symbol images (small) included in the rearranged synthetic symbol images constitute the winning combination, the normal payout symbol images (large) can be displayed in the symbol matrix (SM) with substantially the same sizes as those of the synthetic symbol images. It is therefore possible to give the player an impression as if the normal payout symbol images (small) constituting the winning combination have expanded to the normal payout symbol images (large) as triggered by establishment of the winning combination. Hence it becomes possible to have the player feel interested in a view being as if the normal payout symbol images (small) expand to the normal payout symbol images (large), so as to make the player absorbed in the game.
Moreover, since the normal payout symbol images (large) corresponding to the winning combination are displayed with sizes larger than those of the normal payout symbol images (small) and the bonus payout symbol images (small) in the case of establishment of the winning combination, it is possible to make the player immediately aware of which prize has been established. This enables provision of a game very easy to understand for the player.
According to the slot machine 10 of the first embodiment, the bonus payout symbol image (small) is associated with the progressive jackpot, the free game and the bonus game. Namely, the two kinds of symbol images constituting the synthetic symbol image are both associated with prizes. It is thereby possible to make the player pay attention to both the normal payout symbol images (small) and the bonus payout symbol images (small). Consequently, it is possible to make the player further absorbed in the game.
Moreover, according to the slot machine 10 of the first embodiment, when a combination of the jackpot trigger symbol images (small), free game trigger symbol images (small) or the bonus game trigger symbol images (small) included in the rearranged synthetic symbol images establishes the jackpot trigger, the free game trigger or the bonus game trigger, the jackpot trigger establishment symbol images, the free game trigger establishment symbol images or the bonus game trigger establishment symbol images are displayed in the symbol matrix (SM) in place of the synthetic symbol images including the jackpot trigger symbol images (small), free game trigger symbol images (small) or the bonus game trigger symbol images (small).
Namely, it is possible to display in the symbol matrix (SM) the normal payout symbol images (large) with substantially the same sizes as those of the synthetic symbol images in the case of establishment of the winning combination by the normal payout symbol images, while displaying in the symbol matrix (SM) the symbol images indicating completion of the bonus trigger with substantially the same sizes as those of the synthetic symbol images in the case of completion of the bonus trigger by the bonus payout symbol images (small). It is therefore possible to give the player an impression as if the normal payout symbol images (small) constituting the winning combination have expanded to the normal payout symbol images (large) in the case of establishment of the winning combination by the normal payout symbol images (small), while giving the player an impression as if the jackpot trigger symbol images (small), the free game trigger symbol images (small) or the bonus game trigger symbol images (small) have expanded to the jackpot trigger establishment symbol images, the free game trigger establishment symbol images or the bonus game trigger establishment symbol images in the case of establishment of the jackpot trigger, the free game trigger or the bonus game trigger.
As thus described, it is possible to show the player a view being as if the normal payout symbol images (small) expand to the normal payout symbol images (large) or a view being as if the jackpot trigger symbol images (small), the free game trigger symbol images (small) or the bonus game trigger symbol images (small) expand to the jackpot trigger establishment symbol images, the free game trigger establishment symbol images or the bonus game trigger establishment symbol images, depending upon whether the winning combination is established or the bonus is established. It is thus possible to have the player feel increasingly interested in such unfamiliar views.
In the first embodiment, the case has been described where synthetic symbol images are rearranged in the symbol matrix SM on the lower image display panel 16 (the case where the slot machine 10 is a so-called video slot machine). However, the slot machine of the present invention may be configured so as to stop-display synthetic symbols by using so-called mechanical reels.
In the following, a slot machine 310 having such a configuration is 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.
Moreover, descriptions of parts in the second embodiment, to which the descriptions in the first embodiment are applicable, are omitted.
A general description of a second embodiment will be given by using
In the slot machine 310 (
A display region 328 that displays symbols are provided at the central portion of the lower image display panel 16 provided at a front of the five reels 314. Five display windows 315 (315A, 315B, 315C, 315D and 315E), the rear surfaces of which are visible, are formed inside the display region 328. Three of synthetic symbols drawn on the outer peripheries of the reels 314A, 314B, 3140, 314D, and 314E are displayed through each display window 315A, 315B, 315C, 315D, and 315E.
The synthetic symbol includes a normal payout symbol (small) and a bonus game payout symbol (small). The normal payout symbol (small) corresponds to the normal payout symbol image (small) in the first embodiment. The bonus game payout symbol (small) corresponds to the bonus game payout symbol image (small) in the first embodiment.
Like in the first embodiment, the bonus game payout symbol (small) includes a jackpot trigger symbol (small), a free game trigger symbol (small) and a bonus game trigger symbol (small).
In the second embodiment, when five normal payout symbols (small) are stop-displayed along a line (a winning combination is established), five normal payout symbol images (large) are displayed in predetermined positions of the display region 328. The predetermined position is a position corresponding to the synthetic symbol including the normal payout symbol (small) constituting the established winning combination.
In the example showing in
At this time, when seen from the player, the five synthetic symbols are hidden by the “AIR PLANE” symbol images (large), and seen as in
In an example shown in
At this time, when seen from the player, the four synthetic symbols are hidden by bonus game trigger symbol images (large), and seen as in
Also when four jackpot trigger symbols (small) are stop-displayed along a line on the reels 314A to 314D, four jackpot trigger symbol images (large) are similarly displayed in positions corresponding to four synthetic symbols including the four jackpot trigger symbols (small).
Further, also when four free game trigger symbols (small) are stop-displayed along a line on the reels 314A to 314D, four free game trigger symbol images (large) are similarly displayed in positions corresponding to four synthetic symbols including the four free game trigger symbols (small).
In an example shown in

Also when five jackpot trigger symbols (small) are stop-displayed along a line on the reels 314A to 314E, five jackpot trigger establishment symbol images are similarly displayed in positions corresponding to five synthetic symbols including the five jackpot trigger symbols (small).
Further, also when five free game trigger symbols (small) are stop-displayed along a line on the reels 314A to 314E, five free game trigger establishment symbol images are similarly displayed in positions corresponding to five synthetic symbols including the five free game trigger symbols (small).
There has been described the outline of the second embodiment.
Hereinafter, the second embodiment will be described in more detail.
A reel controller 372 is connected to the main PCB 360.
The sub CPU 61 included in the reel controller 372 controls the rotation and stoppage of the reels 314 (314A, 314B, 314C, 314D and 314E). A motor driving circuit 362 equipped with FPGA (Field Programmable Gate array) 363 and a driver 364 is connected to the sub CPU 361. FPGA 363 is an electronic circuit such as LSI capable of programming and works as a control circuit of a stepping motor 370. The driver 364 works as an amplifier circuit of a pulse to be inputted to the stepping motor 370. The stepping motors 370 (370A, 370B, 370C, 370D and 370E) which rotate each of the reels 314, are connected to the motor driving circuit 362. The stepping motor 370 is a 1-2 phase excitation type stepping motor.
An index detecting circuit 365 and a position change detecting circuit 371 are connected to the sub CPU 361. The index detecting circuit 365 is used for detecting positions (indexes described later) of the rotating reels 314 and can also detect an out-of-order state of the reels 314.
The position change detecting circuit 71 detects a change of stoppage positions of the reels 14 after the stoppage of the rotating of the reels 14.
The position change detecting circuit 371 detects the change of stoppage positions of the reels 314, for example, in a case where the stoppage position is changed by force by a player as if the state of the arrangement of symbols is in a winning state, despite the fact that the state of the arrangement of symbols is not actually in a winning state, and of the like cases. The position change detecting circuit 371 is configured to be capable of detecting the change of stoppage position of the reel 314 by, for example, detecting fins (not shown in the figure) attached with a predetermined space on the inner side of the reel 314.
First, the main CPU 41 executes the processing of steps S411 to S413. However, since the processing is similar to the processing of steps S11 to S13 of
When determining in step S413 that the spin button 23 has been turned on, the main CPU 41 executes symbol determination processing (step S414). In the processing, the main CPU 41 executes a symbol determination program stored in the RAM 43, to determine code Nos. at the time of stoppage of each reel 314. The symbol determination program is a program for determining synthetic symbols (code Nos. corresponding to synthetic symbols) stop-displayed in the display region 328.
Specifically, the main CPU 41 executes a program for random number generation which is included in the symbol determination program, to select a random number value corresponding to each of the five reels 314 out of numeric values of 0 to 255. In the present embodiment, descriptions will be given of a case where random numbers are generated on a program (a case where so-called software random numbers are used). In the present invention, however, a random number generator may be provided, and random numbers may be extracted therefrom (so-called hardware random numbers may be used).
The main CPU 41 determines a code No. of each reel 314 based upon the selected five random number values. Code No. of each reel 314 corresponds to a code No. of the synthetic symbols to be stop-displayed at the central portion of each display window 315. The main CPU 41 determines the codes No. of the respective reels 314, so as to determine a prize. For example, when deciding the code Nos. of the reels 314 to “00”, “00”, “00”, “00”, and “00”, it means that the main CPU 41 determines “AIR PLANE×5” as the prize.
Next, the main CPU 41 stop-displays synthetic symbols on the reels 314A to 314D (step S415). In the processing, the main CPU 41 executes reel rotation control processing. This is processing where, after start rotation of all the reels 314, the rotation of the reels is stopped so that symbols having been determined in step S414 are stop-displayed.
Next, the main CPU 41 determines whether or not the game is in a ready-to-win state for establishment of the jackpot trigger, the free game trigger or the bonus game trigger (step S416). Namely, the main CPU 41 determines whether or not four of at least one kind of bonus payout symbols (small) out of the jackpot trigger symbols (small), the free game trigger symbols (small) and the bonus game trigger symbols (small) have been stop-displayed along a line on the reels 314A to 314D.
When determining that the game is in the ready-to-win state for establishment of the jackpot trigger, the free game trigger or the bonus game trigger, the main CPU 41 executes the following processing in step S417.
Namely, when four bonus game trigger symbols (small) are stop-displayed in a line on the reels 314A to 314D, the main CPU 41 displays bonus game trigger symbol images (large) in the display region 328 of the lower image display panel 16 in such a manner as to cover four synthetic symbols including the four bonus game trigger symbols (small). At this time, the main CPU 41 refers to positional table data included in the game program stored in the RAM 43. The positional table data is data indicating a table where a position of synthetic symbol to be stop-displayed is associated with a position of the display region.
Consequently, when seen from the player, the four synthetic symbols are hidden by the bonus game trigger symbol images (large) (cf.
Further, when four jackpot trigger symbols (small) are stop-displayed along a line on the reels 314A to 314D, the main CPU 41 similarly displays jackpot trigger symbol images (large) in the display region 328 of the lower image display panel 16 in such a manner as to cover four synthetic symbols including the four jackpot trigger symbols (small).
Moreover, when four free game trigger symbols (small) are stop-displayed along a line on the reels 314A to 314D, the main CPU 41 similarly displays free game trigger symbol images (large) in the display region 328 of the lower image display panel 16 in such a manner as to cover four synthetic symbols including the four free game trigger symbols (small).
When determining that the game is not in the ready-to-win state for establishment of any of the jackpot trigger, the free game trigger, or the bonus game trigger, or after executing the processing of step S417, the main CPU 41 shifts the processing to step S418.
In step S418, the main CPU 41 controls rotation of the reels, to stop-display synthetic symbols on the reel 314E (step S418).
Next, the main CPU 41 determines whether or not the jackpot trigger has been established (step S420).
When determining that the jackpot trigger has been established, the main CPU 41 determines whether or not the winning combination has been established on the same row as the row where the jackpot trigger has been established (step S421). In the processing, the main CPU 41 determines whether or not five normal payout symbols (small) have been stop-displayed on the row where the five jackpot trigger symbols (small) in accordance with establishment of the jackpot trigger have been stop-displayed along a line.
When determining that the winning combination has not been established on the same row as the row where the jackpot trigger has been established, the main CPU 41 displays jackpot trigger establishment symbol images in the display region 328 of the lower image display panel 16 in such a manner as to cover five synthetic symbols including the five jackpot trigger symbols (small) in accordance with establishment of the jackpot trigger (step S422).
Next, the main CPU 41 conducts a payout based upon the progressive jackpot (step S423).
When determining in step S421 that the winning combination has been established on the same row as the row where the jackpot trigger has established, the main CPU 41 displays double payout symbol images (large) in the display region 328 of the lower image display panel 16 in such a manner as to cover five synthetic symbols including the five jackpot trigger symbols (small) in accordance with establishment of the jackpot trigger (step S424).
Next, the main CPU 41 conducts a payout based upon a progressive jackpot and also conducts a payout based upon establishment of the winning combination (step S425).
When determining in step S420 that the jackpot trigger has not been established, or after executing the processing of step S423 or S425, the main CPU 41 determines whether or not the winning combination has been established (step S430). In the processing, the main CPU 41 determines whether or not five normal payout symbols (small) have been stop-displayed on any row of the reels 314.
When determining that the winning combination has been established, the main CPU 41 displays normal payout symbol images (large) in the display region 328 of the lower image display panel 16 in such a manner as to cover five synthetic symbols including the five normal payout symbols (small) that constitute the winning combination (step S431).
Consequently, when seen from the player, the five synthetic symbols are hidden by the normal payout symbol images (large) (cf.
Next, the main CPU 41 pays out coins based upon odds in the normal game (normal odds) (step S432).
When determining in step S430 that the winning combination has not been established, or after executing the processing of step S432, the main CPU 41 determines whether or not the bonus game trigger has been established (step S440).
When determining that the bonus game trigger has been established, the main CPU 41 determines whether or not the free game trigger has been established (step S441).
When determining that the free game trigger has not been established, the main CPU 41 displays bonus game trigger establishment symbol images in the display region 328 of the lower image display panel 16 in such a manner as to cover five synthetic symbols including the five bonus game trigger symbol (small) in accordance with establishment of the bonus game trigger (step S442).
Consequently, when seen from the player, the five synthetic symbols are hidden by the bonus game trigger establishment symbol images (cf.
Subsequently, the main CPU 41 executes the bonus game execution processing (step S443), and completes the present subroutine.
When determining in step S441 that the free game trigger has been established, the main CPU 41 displays special bonus game trigger establishment symbol images in the display region 328 of the lower image display panel 16 in such a manner as to cover five synthetic symbols including the five bonus game trigger symbols (small) in accordance with establishment of the bonus game trigger and five synthetic symbols including the five free game trigger symbols (small) in accordance with establishment of the free game trigger (step S444).
Subsequently, the main CPU 41 executes the special bonus game execution processing (step S445), and completes the present subroutine.
When determining that the bonus game trigger has not been established in step S440, the main CPU 41 determines whether or not the free game trigger has been established (step S450).
When determining that the free game trigger has not been established, the main CPU 41 completes the present subroutine.
On the other hand, when determining that the free game trigger has been established, the main CPU 41 displays free game trigger establishment symbol images in the display region 328 of the lower image display panel 16 in such a manner as to cover five synthetic symbols including the five free game trigger symbols (small) in accordance with establishment of the free game trigger (step S451).
Subsequently, the main CPU 41 executes the free game execution processing (step S452), and completes the present subroutine.
According to the slot machine 310 of the second embodiment, the synthetic symbol images each including the normal payout symbol (small) and the bonus payout symbol (small) are stop-displayed on the reels 314A to 314D. Such symbol images formed by synthesizing the two kinds of symbol images are not usually displayed in slot machines, and a player is unfamiliar with such symbols. Therefore, by showing the player such symbols, it is possible to have the player feel freshness. This can result in provision of a game in which the player is unlikely to become bored.
Further, according to the slot machine 310 of the second embodiment, the normal payout symbol (small) is associated with the winning combination. When the normal payout symbols (small) included in the stop-displayed synthetic symbols or a combination thereof constitute the winning combination, the normal payout symbol images (large) are displayed in the symbol matrix (SM) in such a manner as to cover the synthetic symbols (the synthetic symbols stop-displayed along the winning line) including the normal payout symbols (small) constituting the winning combination. The normal payout symbol image (large) has substantially the same picture as that of the normal payout symbol image (small) that constitute the winning combination.
Thereby, when seen from the player, the synthetic symbols each including the normal payout symbol that constitutes the winning combination are hidden by the normal payout symbol images (large). It is therefore possible to give the player an impression as if the normal payout symbols (small) constituting the winning combination have expanded to the normal payout symbol images (large) as triggered by establishment of the winning combination. Hence it becomes possible to have the player feel interested in a view being as if the normal payout symbols (small) expand to the normal payout symbol images (large), so as to make the player absorbed in the game.
Moreover, since the normal payout symbol images (large) corresponding to the winning combination are displayed with sizes larger than those of the normal payout symbols (small) and the bonus payout symbols (small) in the case of establishment of the winning combination, it is possible to make the player immediately aware of which prize has been established. This enables provision of a game very easy to understand for the player.
According to the slot machine 310 of the second embodiment, the bonus payout symbol (small) is associated with the progressive jackpot, the free game and the bonus game. Namely, the two kinds of symbols constituting the synthetic symbol image are both associated with prizes. It is thereby possible to make the player pay attention to both the normal payout symbols (small) and the bonus payout symbols (small). Consequently, it is possible to make the player further absorbed in the game.
Moreover, according to the slot machine 310 of the second embodiment, when a combination of the jackpot trigger symbols (small), the free game trigger symbols (small) or the bonus game trigger symbols (small) included in the stop-displayed synthetic symbols establishes the jackpot trigger, the free game trigger and the bonus game trigger, the jackpot trigger establishment symbol images, free game trigger establishment symbol images or bonus game trigger establishment symbol images are displayed in the display region 328 in such a manner as to cover the synthetic symbols each including the jackpot trigger symbol (small), free game trigger symbol (small) or the bonus game trigger symbol (small).
Namely, it is possible that, when the winning combination is established by the normal payout symbols (small), the normal payout symbol images (large) are displayed in the display region 328 with substantially the same sizes as those of the synthetic symbols, whereas when the bonus game trigger is established by the bonus game payout symbols (small), the symbol images indicating establishment of the bonus game trigger are displayed in the display region 328 with substantially the same sizes as those of the synthetic symbols. It is therefore possible to give the player an impression as if the normal payout symbols (small) constituting the winning combination have expanded to the normal payout symbol images (large) in the case of establishment of the winning combination, while giving the player an impression as if the jackpot trigger symbol images (small), free game trigger symbols (small) or the bonus game trigger symbols (small) have expanded to the jackpot trigger establishment symbol images, the free game trigger establishment symbol images or the bonus game trigger establishment symbol images in the case of establishment of the jackpot trigger, the free game trigger or the bonus game trigger.
As thus described, it is possible to show the player a view being as if the normal payout symbols (small) expand to the normal payout symbol images (large) or a view being as if the jackpot trigger symbols (small), free game trigger symbols (small) or the bonus game trigger symbols (small) expand to the jackpot trigger establishment symbol images, the free game trigger establishment symbol images or the bonus game trigger establishment symbol images, depending upon whether the winning combination is established or the bonus is established. It is thus possible to have the player feel increasingly interested in such unfamiliar views.
It has been described that in the slot machine 310 according to the second embodiment, synthetic symbols are stop-displayed on the reels 314A to 314E. However, the slot machine of the present invention may be configured such that bonus payout symbols (small) are stop-displayed on the reels.
In the following, the same constituents as those of the slot machine 310 according to the second embodiment are described while provided with the same numerals.
Further, descriptions of parts in the third embodiment, to which the descriptions in the first embodiment and the second embodiment are applicable, are omitted.

There has been described the outline of the third embodiment.
Hereinafter, the third embodiment will be described in more detail.
First, the main CPU 41 executes processing of steps S511 to S514. However, since the processing are similar to the processing of steps S411 to S414, the descriptions thereof are omitted here.
Next, the main CPU 41 stop-displays the bonus payout symbols (large) on the reels 314A to 314D, and also rearranges the normal payout symbol images (small) in the symbol image display regions 316A to 316D (step S515).
Next, the main CPU 41 determines whether or not the game is in a ready-to-win state for establishment of the jackpot trigger, the free game trigger or the bonus game trigger (step S516). Namely, the main CPU 41 determines whether or not four of at least one kind of bonus game payout symbols (large) out of the jackpot trigger symbols (large), the free game trigger symbols (large) and the bonus game trigger symbols (large) have been stop-displayed on the reels 314A to 314D.
When determining that the game is in the ready-to-win state for establishment of the jackpot trigger, the free game trigger or the bonus game trigger, the main CPU 41 completes display of normal payout symbol images (small) rearranged on the row corresponding to the row where four bonus payout symbols (large) have been stop-displayed out of the normal payout symbol images (small) rearranged in the symbol image display regions 316A to 316D (step S517).
When determining in step S516 that the game is not in the ready-to-win state for establishment of the jackpot trigger, the free game trigger or the bonus game trigger, or after executing the processing of step S517, the main CPU 41 shifts the processing to step S518.
In step S518, the main CPU 41 conducts bonus payout symbols (large) stop-displayed on the reel 314E, and also rearranges normal payout symbol images (small) in the symbol display region 316E.
Next, the main CPU 41 determines whether or not the jackpot trigger has been established (step S520).
When determining that the jackpot trigger has been established, the main CPU 41 determines whether or not the winning combination has been established on the same row as the row where the jackpot trigger has been established. In the processing, the main CPU 41 determines whether or not five normal payout symbol images (small) are rearranged on the row where the five jackpot trigger symbols (large) in accordance with establishment of the jackpot trigger have been stop-displayed.
When determining that the winning combination has not been established on the same row as the row where the jackpot trigger has been established, the main CPU 41 displays jackpot trigger establishment symbol images in the symbol image display regions 316 in such a manner as to cover the five jackpot trigger symbols (large) in accordance with establishment of the jackpot trigger.
Next, the main CPU 41 conducts a payout based upon the progressive jackpot (step S523).
When determining in step S521 that the winning combination has been established on the same row where the jackpot trigger has been established, the main CPU 41 displays double payout symbol images (large) in the symbol image display regions 316 in such a manner as to cover the five jackpot trigger symbols (large) in accordance with establishment of the jackpot trigger (step S524).
Next, the main CPU 41 conducts a payout based upon the progressive jackpot, and also conducts a payout based upon establishment of the winning combination (step S525).
When determining in step S520 that the jackpot trigger has not been established, or after executing the processing of step S523 or S525, the main CPU 41 determines whether or not the winning combination has been established (step S530). In the processing, the main CPU 41 determines whether or not five normal payout symbol images (small) have been rearranged in any row in the symbol image display regions 316.
When determining that the winning combination has been established, the main CPU 41 completes display of the five normal payout symbol image constituting the winning combination, and displays normal payout symbol images (large) in the symbol image display regions 316 in such a manner as to cover substantially the whole of the bonus payout symbols (large) that are partially covered by the normal payout symbol images (small) (step S531).
Consequently, when seen from the player, the five bonus payout symbols (large) are hidden by the normal payout symbol images (large) (cf.
Next, the main CPU 41 pays out coins based upon odds (normal odds) (step S532).
When determining in step S530 that the winning combination has not been established, or after executing the processing of step S532, the main CPU 41 determines whether or not the bonus game trigger has been established (step S540).
When determining that the bonus game trigger has been established, the main CPU 41 determines whether or not the free game trigger has been established (step S541).
When determining that the free game trigger has not been established, the main CPU 41 displays bonus game trigger establishment symbol images in the symbol image display regions 316 in such a manner as to cover the five bonus game trigger symbols (large) in accordance with establishment of the bonus game trigger (step S542).
Consequently, when seen from the player, the five bonus game trigger symbols (large) are hidden by the bonus game trigger establishment symbol images (cf.
Subsequently, the main CPU 41 executes the bonus game execution processing (step S543), and completes the present subroutine.
When determining in step S541 that the free game trigger has been established, the main CPU 41 displays special bonus game trigger establishment symbol images in the symbol image display regions 316 in such a manner as to cover the five bonus game trigger symbols (large) in accordance with establishment of the bonus game trigger and the five free game trigger symbols (large) in accordance with establishment of the free game trigger (step S544).
Subsequently, the main CPU 41 executes the special bonus game execution processing (step S545), and completes the present subroutine.
When determining in step S540 that the bonus game trigger has not been established, the main CPU 41 determines whether or not the free game trigger has been established (step S550).
When determining that the free game trigger has not been established, the main CPU 41 completes the present subroutine.
On the other hand, when determining that the free game trigger has been established, the main CPU 41 displays free game trigger establishment symbol images in the symbol image display regions 316 in such a manner as to cover the five free game trigger symbols (large) in accordance with establishment of the free game trigger (step S551).
Subsequently, the main CPU 41 executes the free game execution processing (step S552), and completes the present subroutine.
According to the slot machine 310 of the third embodiment, the jackpot trigger symbols (large), the free game trigger symbols (large) or the bonus game trigger symbols (large) are stop-displayed on the reels 314. Further, the normal payout symbol images (small) are rearranged in the symbol image display regions 316 in such a manner as to partially cover the jackpot trigger symbols (large), the free game trigger symbols (large) or the bonus game trigger symbols (large). Therefore, it appears to the player that the synthetic symbols each including the normal symbol image (small) and the partially covered bonus payout symbol image (large) are displayed. Such symbols formed by synthesizing the two kinds of symbols are not usually displayed in slot machines, and a player is unfamiliar with such symbols. Therefore, by showing the player such symbols, it is possible to have the player feel freshness. This can result in provision of a game in which the player is unlikely to become bored.
Further, according to the slot machine of the third embodiment, the normal payout symbol image (small) is associated with the winning combination. When the rearranged normal payout symbol images (small) or a combination thereof constitute the winning combination, the normal payout symbol images (large) are displayed in the symbol image display regions 316 in such a manner as to cover substantially the whole of the bonus payout symbols partially covered by the normal payout symbol images constituting the winning combination.
Thereby, when seen from the player, the whole of the bonus payout symbols (large) partially covered by the normal payout symbol images (small) that constitute the winning combination are hidden by the normal payout symbol images (large). It is therefore possible to give the player an impression as if the normal payout symbol images (small) constituting the predetermined prize have expanded to the normal payout symbol images (large) as triggered by establishment of the winning combination. Hence it becomes possible to have the player feel interested in a view being as if the normal payout symbol images (small) expand to the normal payout symbol images (large), so as to make the player absorbed in the game.
Moreover, since the normal payout symbol images (large) corresponding to the winning combination are displayed with sizes larger than those of the first symbol images in the case of establishment of the winning combination, it is possible to make the player immediately aware of which prize has been established. This enables provision of a game very easy to understand for the player.
