BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a gaming machine in which a video slot game is conducted.
2. Description of Related Art
[0002] In conventional gaming machines, for example, a slot machine, a plurality of reels
are rotated for a predetermined time and coins are paid out corresponding to a symbol
combination which is displayed when all reels are stopped. And in a case that slot
machines are roughly classified based on kinds of reels, there exist a mechanical
type of slot machine in which plural reels on each outer periphery of which symbols
are formed are rotatably provided and a video slot machine in which a plurality of
hypothetical reels (graphics of reels), which are displayed on a display device, are
rotated as shown in Japanese Unexamined Publication No. 2003-180908.
[0003] Here, in the video slot machine, there is no mechanical restriction against each
of the reels. Therefore, for example, it can be independently prepared a plurality
of reels used only for a base game and a plurality of reels used only for a bonus
game. And in the base game the reels used only therefor are rotated on a display device,
and in the bonus game the reels used only therefor are rotated on the display device.
Thereby, progress of a video slot game conducted in the video slot machine can be
variously changed.
[0004] However, in case of the bonus game, the reels used only for the bonus game are always
rotated and stopped and thus a payout characteristic of the bonus game becomes substantially
same in every time the bonus game is conducted. Accordingly, the player is rapidly
accustomed to the bonus game in many cases, even if the reels used only for the base
game and the reels used only for the bonus game are independently prepared as plural
reels used in the video slot game and progress of the video slot game is variously
changed.
SUMMARY OF THE INVENTION
[0005] The present invention has been done to dissolve the above problems and has an object
to provide a gaming machine in which a bonus game characteristic in the video slot
game can be variegated.
[0006] In order to accomplish the above object, according to one aspect of the present invention,
it is provided a gaming machine having a plurality of first reel strips used in a
base game, a display device on which the first reel strips are variably displayed
and stopped, and a game controller for executing a video slot game including the base
game and a bonus game on the display device,
the gaming machine comprising:
a plurality of second reel strips selectively used in the bonus game; and
a lottery device for determining at least one of the second reel strips used in the
bonus game by a lottery;
wherein the game controller replaces at least one of the first reel strips with
the second reel strip determined by the lottery device, and
wherein the game controller executes the bonus game to variably display and stop
both the first reel strips remained after at least one thereof is replaced and the
second reel strip determined by the lottery device on the display device.
[0007] That is to say, in the gaming machine according to the present invention, a video
slot game including a base game and a bonus game is executed on a display device.
At that time, at least one of the second reel strips determined by the lottery device
is replaced with at least one of the first reel strips and the reel strips are variably
displayed and stopped on the display device, thereby the bonus game is executed. Therefore,
since there will exist many combinations of the first reel strips and at least one
of the second reel strips, both reel strips being variably displayed and stopped on
the display device while the bonus game is executed. Accordingly, the bonus game characteristic
in the video slot game can be variegated.
[0008] And according to another aspect of the present invention, it is provided a gaming
machine having a predetermined number of first reel strips used in a base game, a
display device on which the first reel strips are variably displayed and stopped,
and a game controller for executing a video slot game including the base game and
a bonus game on the display device,
the gaming machine comprising:
second reel strips one of which is selectively used in the bonus game; and
a lottery device for determining the one second reel strip used in the bonus game
by a lottery;
wherein the game controller prepares a plurality of strip combinations being comprised
of a number of the first reel strips, the number being obtained by subtracting one
from the predetermined number, and the one second reel strip determined by the lottery
device, and
wherein the game controller selects one of the strip combinations and executes
the bonus game to variably display and stop both the first reel strips and the one
second reel strip included in the one strip combination on the display device.
[0009] According to the gaming machine of the present invention, a video slot game including
a base game and a bonus game is executed on a display device. At that time, the game
controller prepares a plurality of strip combinations being comprised of a number
of the first reel strips, the number being obtained by subtracting one from the predetermined
number, and the one second reel strip determined by the lottery device. And the game
controller selects one of the strip combinations and executes the bonus game to variably
display and stop both the first reel strips and the one second reel strip included
in the one strip combination on the display device. Therefore, since there will exist
many combinations of the first reel strips and the second reel strip, both reel strips
being variably displayed and stopped on the display device while the bonus game is
executed. Accordingly, the bonus game characteristic in the video slot game can be
variegated.

"FISH", "PUNK", "OCTOPUS", "CRAB", "WORM", "SARDINE" are not shown, each symbol shows
a shark, a fish, a punk, an octopus, a crab, a worm and a sardine, respectively. And
"A", "K", "Q" and "J" shows a symbol of English character, respectively.
[0064] Further, "SARDINE" is a scatter symbol to shift to the bonus game as mentioned later
and in a case that more than three "SARDINE" symbols are totally displayed on the
variable display portions 21 to 25, the game state can be shifted to the bonus game.
[0065] Here, in a case that the symbol rows indicated by the first to fifth reel strip 101
to 105 are scrolled on the variable display portions 21 to 25 and thereafter stopped
and displayed, three symbols are stopped and displayed in each variable display portion,
as mentioned in the above.
[0066] And various winning symbol combinations are preset based on plural kinds of symbol
combinations and when the symbol combination corresponding to the winning symbol combination
is stopped on the activated pay line, the payout is added to the credit corresponding
to the winning symbol combination. This point is as same as that in the convention
slot machine, thus explanation thereof will be omitted.
[0067] Next, it will be described a construction of control system in the slot machine 1
with reference to Fig. 4. Fig. 4 is a block diagram schematically showing a control
system of the slot machine 1.
[0068] In Fig. 4, the control system of the slot machine 1 is basically constructed from
a CPU 50, and a ROM 51 and a RAM 52 are connected to the CPU 50. In the ROM 51, a
main process program mentioned later, a base game process program, a bonus game process
program, a lottery table used when it is conducted lottery to determine the symbols
which are stopped and displayed in the base game, a lottery table used when it is
conducted lottery to determine the symbols which are stopped and displayed in the
bonus game, and the other various programs necessary for control of the slot machine
1 and data tables. And the RAM 52 is a memory to temporarily store various data calculated
by the CPU 50.
[0069] And to the CPU 50, a clock pulse generator 53 for generating standard clock pulses
and a frequency divider 54 are connected, and a random number generator 55 for generating
random numbers and a random number sampling circuit 56 are also connected. The random
number sampled through the random number sampling circuit 56 is utilized in various
lotteries of the winning symbol combinations and the like. Further, to the CPU 50,
the COLLECT switch 45 attached to the COLLECT button 31, the GAME · RULES switch 46
attached to the GAME RULES button 32, the 1-BET switch 57 attached to the BET 1 PER
LINE button 33, the 2-BET switch 58 attached to the BET 2 PER LINES button 34, the
3-BET switch 59 attached o the BET 3 PER LINES button 35, the 5-BET switch 60 attached
to the BET 5 PER LINES button 36, the 8-BET switch 60 attached to the BET 8 PER LINES
button 37, the WIN·START switch 47 attached to the WIN START FEATURE button 38, the
1-LINE switch 62 attached to the RED PLAY 1 LINE button 39, the 2-LINES switch 63
attached to the PLAY 2 LINES button 40, the 5-LINES switch 64 attached to the PLAY
5 LINES button 41, the 20-LINES switch 65 attached to the PLAY 20 LINES button 42,
the 25-LINES switch 66 attached to the BLACK PLAY 25 LINES button 43 and the GAMBLE
· RESERVE switch 48 attached to the GAMBLE RESERVE button 44 are connected, respectively.
The CPU 50 conducts control to execute various operations each of which corresponds
to each button, based on the switch signal output from each switch by press thereof.
[0070] Further, to the CPU 50, the coin sensor 49 arranged in the coin insertion slot 9
and the bill sensor 67 arranged in the bill insertion portion 10 are respectively
connected. The coin sensor 49 detects coins inserted from the coin insertion slot
9 and the CPU 50 calculates the number of inserted coins based on the coin detection
signal output from the coin sensor 49. The bill sensor 67 detects kinds and sum of
the bill inserted from the bill insertion portion 10 and the CPU 50 calculates the
credit number equal to the sum of bill, based on the bill detection signal output
from the bill sensor 67.
[0071] To the CPU 50, a hopper 71 is connected through a hopper drive circuit 70. When a
drive signal is output to the hopper drive circuit 70 from the CPU 50, the hopper
71 pays out a predetermined number of coins from the coin payout opening 15.
[0072] And to the CPU 50, a coin detection portion 73 is connected through a payout completion
signal circuit 72. The coin detection portion 73 is arranged in the coin payout opening
15 and when the coin detection portion 73 detects that a predetermined number of coins
are paid out from the coin payout opening 15, a coin payout detection signal is output
to the payout completion signal circuit 72 from the coin detection portion 73, thereby
the payout completion signal circuit 72 outputs a payout completion signal to the
CPU 50. Further, to the CPU 50, the upper liquid crystal display 3 and the lower liquid
crystal display 4 are connected through a liquid crystal drive circuit 74, and the
upper liquid crystal display 3 and the lower liquid crystal display 4 are controlled
by the CPU 50.
[0073] Here, as shown in Fig. 5, the liquid crystal drive circuit 74 is constructed from
a program ROM 81, an image ROM 82, an image control CPU 83, a work RAM 84, a VDP (video
display processor) 85 and a video RAM 68. And in the program ROM 81, there are stored
an image control program for controlling display of the upper liquid crystal display
3 and the lower liquid crystal display 4 and various selection tables. And in the
image ROM 82, for example, there are stored dot data for forming images of the symbol
rows indicated by the first to fifth reel strips 101 to 105 in Fig. 6, such images
being displayed on the lower liquid crystal display 4 (or variable display portions
21 to 25). And the image control CPU 83 determines the images displayed on the upper
liquid crystal display 3 and the lower liquid crystal display 4 among the dot data
stored beforehand in the image ROM 82, according to the image control program stored
beforehand in the program ROM 81 based on parameters set by the CPU 50. Further, the
work RAM 84 functions as temporary memory when the image control program is executed
by the image control CPU 83. And the VDP 85 forms images corresponding to display
contents determined by the image control CPU 83 and outputs such images to the upper
liquid crystal display 3 and the lower liquid crystal display 4. Thereby, for example,
the symbol rows indicated by the first to fifth reel strips 101 to 105 are scrolled
and displayed on the lower liquid crystal display 4 (or the variable display portions
21 to 25). Here, the video RAM 86 functions as temporary memory when images are formed
by the VDP 85.
[0074] And to the CPU 50, LEDs 78 are connected through a LED drive circuit 77. Many LEDs
78 are arranged on the front plane of the slot machine 1 and are controlled so as
to turn on or turn off by the LED drive circuit 77 based on the drive signal from
the CPU 50, when various effects are done. Further, a sound output circuit 79 and
a speaker 80 are connected to the CPU 50 and the speaker 80 produces various effect
sounds when various effects are conducted based on the output signal from the sound
output circuit 79.
[0075] To the CPU 50, a touch panel 121 is connected through a touch panel drive circuit
122. The touch panel 121 is arranged on the image plane of the lower liquid crystal
display 4 and when the player touches on the variable display portions 21 to 25 by
the finger, the touch panel 121 can recognize through the touch panel drive circuit
122 not only the variable display portion on which the player touches among the variable
display portions 21 to 25 but also the stop area on which the player touches among
the first stop areas 211, 221, 231, 241, 151, the second stop areas 212, 222, 232,
242, 252 and the third stop areas 213, 223, 233, 243, 253.
[0076] That is to say, the touch panel 121 can recognize through the touch panel drive circuit
122 the variable display portion on which the player touches among the variable display
portions 21 to 25, based on coordinate information of the portion which is touched
by the player.
[0077] Here, it will be described with reference to Fig. 9 the lottery table which is used
when the symbols stopped and displayed on the activated pay line L1 shown in Fig.
11 are determined, when the base game is conducted by using five variable display
portions 21 to 25 in the slot machine 1.
[0078] The symbols stopped and displayed on the activated pay line L1 shown in Fig. 11 are
determined every each of the variable display portions 21 to 25. In order to realize
this, code Nos. "00" ~ "29" are respectively allotted to the symbol in each symbol
row indicated by the first to fifth reel strips 101 to 105 as shown in Fig. 6, in
order of the upper most symbol. And the lottery table shown in Fig. 9 is provided
beforehand. Further, five random numbers are sampled by the random number sampling
circuit 56 so as to correspond to each of the variable display portions 21 to 25.
[0079] Hereinafter, the symbol row indicated by the first reel strip 101 in Fig. 6 will
be described. The symbols in the symbol row are scrolled on the variable display portion
21. At that time, if the random number sampled by the random number sampling circuit
56 is "0", the symbol "J" (English character) allotted to the code No. "00" is stopped

[0097] Here, concerning with only the payout obtained by the symbol "SARDINE", the payout
number calculated by multiplying the payout number shown in Fig. 8 with the total
bet number (a product of the bet number and the number of activated pay line) is added
to the credit. At that time, if it exists the payout other than the payout on the
basis of the symbol "SARDINE", such payout is also added to the credit.
[0098] And as for the symbol "SARDINE", in a case that more than three symbols "SARDINE"
are totally stopped and displayed on the variable display portions 21 to 25 with no
relation to the activated pay lines, not only the above payout can be obtained but
also the game state can be shifted to the bonus game.
[0099] Here, the bonus game is a game which is conducted after the base game is terminated,
and in many cases the bonus game is generally more beneficial for the player. If the
game state shifts to the bonus game, 15 - 25 games can be continuously and automatically
done without betting any credits corresponding to a result of the lottery conducted
when the game state shifts to the bonus game.
[0100] Here, as the bet number and the number of activated pay line in the bonus game, the
bet number and the number of activated pay line set in the base game are utilized,
respectively. And in the bonus game, although the winning symbol combinations and
payouts thereof in the bonus game are as same as those in the base game, the symbol
"SHARK" is handled as the symbol "LOBSTER" (shown in Fig. 7) and if more than three
symbols "SARDINE" totally appear (are totally stopped and displayed), the game state
in the bonus game can be again shifted to the bonus game. Therefore, the player can
obtain a lot of credits in many cases.
[0101] Next, the main process program done in the slot machine 1 will be described with
reference to Fig. 36. Fig. 36 is a flowchart of the main process program. In Fig.
36, at first, in step (abbreviated as "S" hereinafter) 11, a start acceptance process
shown in Fig. 37 is done. This process is a process for accepting the switch signal
output from the 1-BET switch 57, the 2-BET switch 58, the 3-BET switch 59, the 5-BET
switch 60, the 8-BET switch 61, the 1-LINE switch 62, the 2-LINES switch 63, the 5-LINES
switch 64, the 20-LIENS switch 65, the 25-LINES switch 66, based on operation of the
BET 1 PER LINE button 33, the BET 2 PER LINES button 34, the BET 3 PER LINES button
35, the BET 5 PER LINES 36, the BET 8 PER LINES button 37, the RED PLAY 1 LINE button
39, the PLAY 2 LINES button 40, the PLAY 5 LINES button 41, the PLAY 20 LINES button
42 or the BLACK PLAY 25 LINES button 43. When the switch signal output from each switch
is accepted, the game is started.
[0102] And in S12, a lottery process shown in Fig. 16 mentioned later is done based on the
switch signal output from the 1-LINE switch 62, the 2-LINES switch 63, the 5-LINES
switch 64, the 20-LINES switch 65, the 25-LINES switch 66.
[0103] Here, if the bonus game is won, a repeat number of the bonus game is determined.
In this case, for example, such repeat number is selected among 10 - 25 games by a
lottery.
[0104] Next, in S13, a base game process shown in Fig. 17 mentioned later is done. Thereafter,
procedure shifts to S14 and it is determined whether or not the bonus game is won.
Concretely, in the lottery process in S12, if more than three symbols "SARDINE" totally
appear (are stopped and displayed) on the variable display portions 21 to 25 with
no relation to the activated pay lines, the bonus game is won (S14: YES). Thereby,
procedure shifts to S15 and the main process program is terminated after the bonus
game process shown in Fig. 40 mentioned later is done. On the other hand, in the lottery
process of S12, if more than three symbols "SARDINE" does not totally appear (are
not stopped and displayed) on the variable display portions 21 to 25 with no relation
to the activated pay lines, the bonus game is not won (S14: NO), thereby the main
process program is terminated.
[0105] Next, the start acceptance process program conducted in the slot machine 1 will be
described with reference to Fig. 37. Fig. 37 is a flowchart of the start acceptance
process program. In S11 of the main process program shown in Fig. 36, the start acceptance
process is conducted. Here, to conduct this process, at first, procedure shifts to
S21 of Fig. 37 and it is determined whether or not a predetermined time (for example,
15 seconds) is elapsed. Here, if it is determined that the predetermined time is not
elapsed (S21: NO), procedure shifts to S23, and on the other hand, if it is determined
that the predetermined time is elapsed (S21: YES), demonstration effect is done on
the upper liquid crystal display 3 or the lower liquid crystal display 4 in S22, thereafter
procedure shifts to S23. And in S23, it is determined whether or not operation of
the RED PLAY 1 LINE button 39, the PLAY 2 LINES button 40, the PLAY 5 LINES button
41, the PLAY 20 LINES button 42 or the BLACK PLAY 25 LINES button 43 is done. Here,
if it is determined that operation of the RED PLAY 1 LINE button 39 and the like is
not done (S23: NO), procedure returns to S21 and the above procedures are repeated.
On the other hand, if it is determined that operation of the RED PLAY 1 LINE button
39 and the like is done (S23: YES), procedure returns to the main process program
of Fig. 36 and shifts to the lottery process in S12 even while the demonstration effect
is done.
[0106] Here, in the determination process in S23, such determination in S23 may be conducted
based on the other input signals other than the above operation signals.
[0107] Next, the lottery process program done in the slot machine 1 will be described with
reference to Fig. 38. Fig. 38 is a flowchart of the lottery process program. In S12
of the main process program shown in Fig. 36, the lottery process is done. To conduct
this process, at first, procedure shifts to S31 of Fig. 38 and a symbol determination
process is conducted. Here, the symbols stopped and displayed on the first pay line
L1 in the base game are determined every each of the variable display portions 21
to 25. Concretely, as mentioned above, five random number values are sampled by the
random number sampling circuit 56 so as to correspond to each of the variable display
portions 21 to 25 and the symbols stopped and displayed are determined through the
code Nos. based on the lottery table shown in Fig. 9. And if the symbols stopped and
displayed on the activated pay line are determined, a determination process of the
winning symbol combination is done in S32, thereafter procedure returns to the main
process program in Fig. 36 and shifts to the base game process in S13. Here, concretely
speaking, in the determination process of the winning symbol combination, the winning
symbol combination and the payout thereof are determined based on the table shown
in Fig. 8 through the code No. obtained in S31, as mentioned.
[0108] Next, the base game process program done in the slot machine 1 will be described
with reference to Fig. 39. Fig. 39 is a flowchart of the base game process program.
In S13 of the main process program shown in Fig. 36, the base game is conducted. To
realized this, at first, in S41 of Fig. 39, scroll of each of the symbols is done
on the variable display portions 21 to 25 based on the switch signal output from the
1-LINE switch 62, the 2-LINES switch 63, the 5-LINES switch 64, the 20-LINES switch
65 or the 25-LINES switch 66, the switch signal being accepted in S11 of Fig. 36.
[0109] And in S42, scroll of each of the symbols on the variable display portions 21 to
25 is stopped.
[0110] Further, in S43, according to the symbol combination corresponding to the winning
symbol combination stopped and displayed on the variable display portions 21 to 25,
the credit corresponding to the payout determined on the basis of the table shown
in Fig. 8 is paid out. Here, after process in S43 is done, procedure shifts to the
main process program shown in Fig. 36 and shifts to the determination process in S14.
[0111] Next, the bonus game process program done in the slot machine 1 will be described
with reference to Fig. 39. Fig. 39 is a flowchart of the bonus game process program.
In S14 of the main process program shown in Fig. 36, if it is determined that the
bonus game is won (S14: YES), procedure shifts to S15 of Fig. 36 and the bonus game
process is conducted. To realize this, at first, procedure shifts to S39 shown in
Fig. 39 and the lottery process during the bonus game is done. Here, in the bonus
game, the symbols stopped and displayed on the first pay line L1 are determined every
each of the variable display portions 21 to 25. Concretely, as mentioned, five random
number values are sampled by the random number sampling circuit 56 so as to correspond
to each of the variable display portions 21 to 25, and the symbols stopped and displayed
are determined through the code Nos. based on the lottery table shown in Fig. 9. And
if the symbols stopped and displayed on the first pay line L1 are determined, the
winning symbol combination and the payout thereof are determined based on the table
shown in Fig. 8 through the code Nos.
[0112] Further, in the rotation process in S52, scroll of each of the symbols is automatically
done on the variable display portions 21 to 25.
[0113] And in the stop control process in S53, scroll of each of the symbols on the variable
display portions 21 to 25 is stopped.
[0114] Further, in the payout process in S54, according to the symbol combination corresponding
to the winning symbol combination stopped and displayed on the variable display portions
21 to 25, the credit corresponding to the payout determined based on the table in
Fig. 8 (however, the symbol "SHARK" is handled as the symbol "LOBSTER (shown in Fig.
7)) is paid out.
[0115] Next, procedure shifts to S55 and it is determined whether or not the execution number
of times of the bonus game reaches to the number of times determined in S12 of Fig.
36. At that time, if it is determined that the execution number of times of the bonus
game does not reach to the number of times already determined (S55: NO), procedure
returns to S51 and the above processes are repeated. On the other hand, if it is determined
that the execution number of times of the bonus game reaches to the number of times
already determined (S55: YES), the bonus game process program is terminated.
[0116] Here, if the bonus game is won in S51, the repeat number of times of the bonus game
is determined again and the determined repeat number of times is added to the "number
of times determined in S12 of Fig. 36" used in the determination process in S55. Thereby,
when the bonus game is won during the bonus game, procedure can again shift to the
bonus game. Concretely speaking, for example, in a case that procedure shifts to the
bonus game with 20 number of times for the first time and the bonus game with 17 number
of times is won in the twelfth bonus game, the bonus games are conducted in 25 times
(20 times - 12 times + 17 times) thereafter.
[0117] And if the credit can be finally obtained in the bonus game, a double down game to
bet the credit is done after the bonus game is terminated. This double down game will
be omitted.
[0118] By the way, in the slot machine 1 of the embodiment, although the symbol rows variably
displayed on each of the variable display portions 21 to 24 of the lower liquid crystal
display 4 while being scrolled are as same as those in the base game when the bonus
game is conducted, the symbol row variably displayed on the variable display portion
25 of the lower liquid crystal display 4 while being scrolled is any one of the symbol
rows shown by the 5-1 reel strip 106, the 5-2 reel strip 107, the 5-3 reel strip 108,
the 5-4 reel strip 109 and the 5-5 reel strip 110, in Fig. 41.
[0119] And in the slot machine 1 of the embodiment, when the bonus game is conducted, the
process shown in Fig. 43 is done at the time point W1 right before the bonus game
process in S15 in the main process program of Fig. 36, in order to select the symbol
row variably displayed on the variable display portion 25 of the lower liquid crystal
display 4 while being scrolled. That is, in the main process program in Fig. 36, when
it is determined that the bonus game is won (S14: YES), procedure shifts to S101 in
Fig. 43 and the lottery of the reel strip is done. Concretely, one random number value
is sampled through the random number sampling circuit 56 and the symbol row is determined
based on the lottery table shown in Fig. 44. And after the symbol row is determined,
procedure returns to the main process program in Fig. 36 and shifts to the bonus game
process in S15.
[0120] Therefore, according to the lottery table in Fig. 44, in a case that the random number
value sampled through the random number sampling circuit 56 in S101 of Fig. 43 is
"0", the symbol row indicated by the 5-1 reel strip 106 is selected. And in a case
that the random number value sampled through the random number sampling circuit 56
is "1", the symbol row indicated by the 5-2 reel strip 107 is selected. Further, in
a case that the random number value sampled through the random number sampling circuit
56 is "2", the symbol row indicated by the 5-3 reel strip 108 is selected. And in
a case that the random number value sampled through the random number sampling circuit
56 is "3", the symbol row indicated by the 5-4 reel strip 109 is selected. Further,
in a case that the random number value sampled through the random number sampling
circuit 56 is "4", the symbol row indicated by the 5-5 reel strip 110 is selected.
[0121] Here, comparing the symbol row mentioned above with the symbol row indicated by the
fifth reel strip 105 variably displayed on the variable display portion 25 of the
lower liquid crystal display 4 while being scrolled when the base game is done, there
exist the following characteristics in the symbol row indicated by the 5-1 reel strip
106, the 5-2 reel strip 107, the 5-3 reel strip 108, the 5-4 reel strip 109 and the
5-5 reel strip 110 in Fig. 41.
[0122] That is to say, the symbol row indicated by the 5-1 reel strip 106 shown in Fig.
41 is as same as the symbol row indicated by the reel strip 105 in Fig. 6, except
that the symbol "LOBSTER" (shown in Fig. 7) is allotted to the code No. "10". Therefore,
when the symbol row indicated by the 5-1 reel strip 106 in Fig. 41 is selected and
game state shifts to the bonus game, it can be added in the bonus game the characteristic
that the symbol "LOBSTER" (shown in Fig. 7) is aligned with twice probability in comparison
with the base game (the characteristic that it is easier to obtain the winning symbol
combination than in the base game).
[0123] Here, this case corresponds to a case shown in Fig. 46 (a) mentioned later.
[0124] And the symbol row indicated by the 5-2 reel strip 107 shown in Fig. 41 is as same
as the symbol row indicated by the reel strip 105 in Fig. 6, except that the symbol
"SARDINE" is allotted to the code No. "21". Therefore, when the symbol row indicated
by the 5-2 reel strip 107 in Fig. 41 is selected and game state shifts to the bonus
game, it can be added in the bonus game the characteristic that the symbol "SARDINE"
is aligned with twice probability in comparison with the base game, thereby the bonus
game can be again easily won (the characteristic that it is easier to continuously
obtain the bonus game).
[0125] Here, this case corresponds to a case shown in Fig. 46 (b) mentioned later.
[0126] And the symbol row indicated by the 5-3 reel strip 108 shown in Fig. 41 is as same
as the symbol row indicated by the reel strip 105 in Fig. 6, except that the symbol
"LOBSTER" (shown in Fig. 7) is allotted to the code No. "21". Therefore, when the
symbol row indicated by the 5-3 reel strip 108 in Fig. 41 is selected and game state
shifts to the bonus game, it can be added in the bonus game the characteristic that
the symbol "LOBSTER" (shown in Fig. 7) is aligned with triple probability in comparison
with the base game, thereby the bonus game can be again easily won (the characteristic
that it is easier to continuously obtain the bonus game).
[0127] Here, this case corresponds to a case shown in Fig. 46 (c) mentioned later.
[0128] And the symbol row indicated by the 5-4 reel strip 109 shown in Fig. 41 is as same
as the symbol row indicated by the reel strip 105 in Fig. 6, except that the symbol
"LOBSTER" (shown in Fig. 7) is allotted to the code No. "12" and the symbol "SARDINE"
is allotted to the code No. "21". Therefore, when the symbol row indicated by the
5-4 reel strip 109 in Fig. 41 is selected and game state shifts to the bonus game,
it can be added in the bonus game the characteristic that the symbol "LOBSTER" (shown
in Fig. 7) is aligned with twice probability (the characteristic that it is easier
to obtain the winning symbol combination than in the base game) and the symbol "SARDINE"
is aligned with twice probability in comparison with the base game, thereby the bonus
game can be again easily won (the characteristic that it is easier to continuously
obtain the bonus game).
[0129] Here, this case corresponds to a case shown in Fig. 46 (d) mentioned later.
[0130] And the symbol row indicated by the 5-5 reel strip 110 shown in Fig. 41 is exactly
as same as the symbol row indicated by the reel strip 105 in Fig. 6. Therefore, when
the symbol row indicated by the 5-5 reel strip 110 in Fig. 41 is selected and game
state shifts to the bonus game, it is added in the bonus game the characteristic which
is as same as that in the base game, except that the symbol "SHARK" is handled as
the symbol "LOBSTER" (shown in fig. 7).
[0131] Here, this case corresponds to a case shown in Fig. 46 (e) mentioned later.
[0132] Here, the symbol rows indicated by the 5-1 reel strip 106, the 5-2 reel strip 107,
the 5-3 reel strip 108, the 5-4 reel strip 109 and the 5-5 reel strip 110 shown in
Fig. 41 are stored in the image ROM 82.
[0133] As mentioned, when the process of S101 in Fig. 43 is executed, the CPU 50 functions
as "lottery device".
[0134] And when the main process program in Fig. 36 is executed, the CPU 50 functions as
"game control device".
[0135] As mentioned in detail, in the slot machine 1 according to the embodiment, among
the symbol rows variably displayed on each of the variable display portions 21 to
25 of the lower liquid crystal display 4 while being scrolled when the base game is
executed, there exist the symbol rows indicated by the first reel strip 101, the second
reel strip 102, the third reel strip 103, the fourth reel strip 104 and the fifth
reel strip 105. And among the symbol rows variably displayed on each of the variable
display portions 21 to 25 of the lower liquid crystal display 4 while being scrolled
when the bonus game is executed, there exist the symbol rows indicated by the 5-1
reel strip 106, the 5-2 reel strip 107, the 5-3 reel strip 108, the 5-4 reel strip
109 and the 5-5 reel strip 110.
[0136] Here, for explanation convenience sake, it is supposed that a hypothetical rotational
body on an outer periphery of which the symbol row indicated by the first reel strip
101 in Fig. 6 is formed is the first hypothetical reel 101R, a hypothetical rotational
body on an outer periphery of which the symbol row indicated by the second reel strip
102 in Fig. 6 is formed is the second hypothetical reel 102R, a hypothetical rotational
body on an outer periphery of which the symbol row indicated by the third reel strip
103 in Fig. 6 is formed is the third hypothetical reel 103R, a hypothetical rotational
body on an outer periphery of which the symbol row indicated by the fourth reel strip
104 in Fig. 6 is formed is the fourth hypothetical reel 104R, and a hypothetical rotational
body on an outer periphery of which the symbol row indicated by the fifth reel strip
105 in Fig. 6 is formed is the fifth hypothetical reel 105R.
[0137] Further, it is supposed that a hypothetical rotational body on an outer periphery
of which the symbol row indicated by the 5-1 reel strip 106 in Fig. 41 is formed is
the 5-1 hypothetical reel 106R, a hypothetical rotational body on an outer periphery
of which the symbol row indicated by the 5-2 reel strip 107 in Fig. 41 is formed is
the 5-2 hypothetical reel 107R, a hypothetical rotational body on an outer periphery
of which the symbol row indicated by the 5-3 reel strip 108 in Fig. 41 is formed is
the 5-3 hypothetical reel 108R, a hypothetical rotational body on an outer periphery
of which the symbol row indicated by the 5-4 reel strip 109 in Fig. 41 is formed is
the 5-4 hypothetical reel 109R, and a hypothetical rotational body on an outer periphery
of which the symbol row indicated by the 5-5 reel strip 110 in Fig. 41 is formed is
the 5-5 hypothetical reel 110R.
[0138] Thus, in the slot machine 1 according to the embodiment, as shown in Fig. 1 (a),
when the base game is conducted, the first hypothetical reel 101R is variably displayed
and stopped on the variable display portion 21 of the lower liquid crystal display
4, the second hypothetical reel 102R is variably displayed and stopped on the variable
display portion 22 of the lower liquid crystal display 4, the third hypothetical reel
103R is variably displayed and stopped on the variable display portion 23 of the lower
liquid crystal display 4, the fourth hypothetical reel 104R is variably displayed
and stopped on the variable display portion 24 of the lower liquid crystal display
4 and the fifth hypothetical reel 105R is variably displayed and stopped on the variable
display portion 25. However, the 5-1 hypothetical reel 106R, the 5-2 hypothetical
reel 107R, the 5-3 hypothetical reel 108R, the 5-4 hypothetical reel 109R and the
5-5 hypothetical reel 110R are not used in the base game.
[0139] On the other hand, as shown in Fig. 1 (b), when the bonus game is conducted, the
first hypothetical reel 101R is variably displayed and stopped on the variable display
portion 21 of the lower liquid crystal display 4, the second hypothetical reel 102R
is variably displayed and stopped on the variable display portion 22 of the lower
liquid crystal display 4, the third hypothetical reel 103R is variably displayed and
stopped on the variable display portion 23 of the lower liquid crystal display 4,
the fourth hypothetical reel 104R is variably displayed and stopped on the variable
display portion 24 of the lower liquid crystal display 4. And further, on the variable
display portion 25 of the lower liquid crystal display 4, one hypothetical reel is
selected among the 5-1 hypothetical reel 106R, the 5-2 hypothetical reel 107R, the
5-3 hypothetical reel 108R, the 5-4 hypothetical reel 109R and the 5-5 hypothetical
reel 110R and the symbol row corresponding to the reel strip of the selected hypothetical
reel is variably displayed and stopped on the variable display portion 25. In this
case, the fifth hypothetical reel 105R is not used.
[0140] Therefore, in the base game as shown in Fig. 45, the game is conducted by using only
the combination of the first hypothetical reel 101R, the second hypothetical reel
102R, the third hypothetical reel 103R, the fourth hypothetical reel 104R and the
fifth hypothetical reel 105R.
[0141] On the contrary, in the bonus game, the game is conducted by using one combination
selected from five combinations, that is, the combination of the first hypothetical
reel 101R, the second hypothetical reel 102R, the third hypothetical reel 103R, the
fourth hypothetical reel 104R and the 5-1 hypothetical reel 106R as shown in Fig.
46 (a), the combination of the first hypothetical reel 101R, the second hypothetical
reel 102R, the third hypothetical reel 103R, the fourth hypothetical reel 104R and
the 5-2 hypothetical reel 107R as shown in Fig. 46 (b), the combination of the first
hypothetical reel 101R, the second hypothetical reel 102R, the third hypothetical
reel 103R, the fourth hypothetical reel 104R and the 5-3 hypothetical reel 108R as
shown in Fig. 46 (c), the combination of the first hypothetical reel 101R, the second
hypothetical reel 102R, the third hypothetical reel 103R, the fourth hypothetical
reel 104R and the 5-4 hypothetical reel 109R as shown in Fig. 46 (d) and the combination
of the first hypothetical reel 101R, the second hypothetical reel 102R, the third
hypothetical reel 103R, the fourth hypothetical reel 104R and the 5-5 hypothetical
reel 110R as shown in Fig. 46 (e). As mentioned, the bonus game is conducted by using
any one combination among five kinds of combinations.
[0142] Thus, in the slot machine 1 according to the embodiment, the video slot game constructed
from the base game and the bonus game is conducted on the lower liquid crystal display
4, and the first hypothetical reel 101R, the second hypothetical reel 102R, the third
hypothetical reel 103R, the fourth hypothetical reel 104R and the fifth hypothetical
reel 105R are used in the base game, and on the other hand in the bonus game, the
fifth hypothetical reel 105R is replaced with one of the 5-1 hypothetical reel 106R,
the 5-2 hypothetical reel 107R, the 5-3 hypothetical reel 108R, the 5-4 hypothetical
reel 109R and the 5-5 hypothetical reel 110R, the hypothetical reel to be replaced
being specified in the lottery (S101) which is done when the game state shifts from
the base game to the bonus game, and the replaced hypothetical reel is used with the
first to fourth hypothetical reels 101R to 104R in the bonus game. Thereby, since
there exist five kinds of combinations of the hypothetical reels (see Fig. 46 (a)
- (e)) which are variably displayed and stopped on the lower liquid crystal display
4 while the bonus game is executed, the characteristic of the bonus game in the video
slot game can be variegated.
[0143] Here, the present invention is not limited to the above embodiment and various changes
and modifications can be done within the scope of the present invention.
[0144] For example, in the slot machine 1 of the embodiment, although the lottery to select
the symbol row which is replaced and used when the game state shifts to the base game
to the bonus game is done at the point time W1 right before the bonus game process
in S 15 is executed, such lottery may be done when the game state again shifts from
the bonus game to the bonus game and every time the lottery process of the bonus game
(S51) is done.
[0145] And in the slot machine 1 of the embodiment, although the symbol row which is replaced
when the game state shifts from the base game to the bonus game is the symbol row
which is variably displayed on the variable display portion 25 of the lower liquid
crystal display 4 while being scrolled, the symbol row variably displayed on any one
of the variable display portions 21 to 24 of the lower liquid crystal display 4 while
being scrolled may be replaced. And the symbol rows variably displayed on more than
two variable display portions among the variable display portions 21 to 25 of the
lower liquid crystal display 4 may be replaced. Further, in these case, the variable
display portion (s) on which the symbol row (s) replaced are variably displayed while
being scrolled may be set beforehand or selected by the lottery.
[0146] And in the slot machine 1 of the embodiment, although the symbol row is replaced
when the game state shifts from the base game to the bonus game, the symbol row may
be replaced every time the base game is started.
[0147] Further, in the slot machine 1 of the embodiment, although the symbol row, which
is replaced when the game state shifts to the bonus game and used in the bonus game,
is determined based on the lottery table in Fig. 44 in which one random number value
sampled by the random number sampling circuit 56 corresponds to one code No., the
symbol row which is replaced when the game state shifts to the bonus game and used
in the bonus game may be determined based on the lottery table shown in Fig. 47 in
which a specific range of the random number sampled by the random number sampling
circuit 56 corresponds to one reel strip.
[0148] Further, in the slot machine 1 of the embodiment, the symbol stopped and displayed
on the first pay line L1 is determined every each of the variable display portions
21 to 25 in the base game and the bonus game, based on the lottery table in Fig. 9
in which one random number value sampled through the random number sampling circuit
56 and one code No. are corresponded with each other. As for this point, for example,
the symbol stopped and displayed on the first pay line L1 may be determined every
each of the variable display portions 21 to 25, based on the lottery table in Fig.
42 in which a specific range of the random numbers sampled through the random number
sampling circuit 56 corresponds to one code No..
[0149] As mentioned, the present invention can be adopted for a gaming machine in which
the video slot game is executed by changing the hypothetical reels used in the bonus
game so as to become different from the hypothetical reels used in the base game.
