Abstract

<P>PROBLEM TO BE SOLVED: To make a win, the probability of occurrence of which is low due to the total number and kinds of symbols forming a symbol line occur with a reasonable frequency without giving a feeling of unnaturalness to a player. <P>SOLUTION: Display windows 3 are arranged in the form of a 3 by 3 matrix. Reels are rotated behind the display windows. Each of the reels bears an array of 12 symbols, including five 'cherry' symbols and one 'red 7' symbol. The simple probability of arrangement of the 'red 7' symbols in all of the display windows 3 is a very low (1/12)<SP>9</SP>. The probability of arrangement of the 'cherry' symbols is a somewhat high (5/12)<SP>9</SP>. When all of the display windows 3 are filled with the 'cherry' symbols, the reel in the back of the display window 3a in the center rotates, providing a subsidiary game. When the reel stops rotating and the 'red 7' symbol is determined, the reels provided behind another display windows 3 rotate. The reels are controlled to stop so as to make the 'red 7' symbols appear in all of the display windows 3, leading to an 'all red 7s' big win, the probability of occurrence of which is very low. <P>COPYRIGHT: (C)2003,JPO

What do you do against the base game that has just started
Decide whether to give such a prize. Therefore, the ROM 22
Is a random number considering the payout rate of the slot machine.
And data that associate symbol combinations with
Have been. Then, the CPU 10 executes each of the activated input.
Sampling of random numbers for each prize line
Determine the symbols for each reel to be combined on the line
I do. On the other hand, for each of the reels 5a to 5i,
How the symbols are arranged from the reference position
Is known in advance, and the control data is also written to the ROM 22.
The count value of the counter is
Perform stop control of stepping motor while referring to
Symbol set determined according to the random value
Stop the reel so that the alignment is aligned on the predetermined winning line
Will be able to do that. Therefore, the reel 5a
To 5i are sequences determined based on random number sampling.

Reel body connected to 6a to 6i and affixed to its outer periphery
Symbol sheet. symbol
The sheet has a plurality of types of thin
The bols are marked at a constant pitch. Fig. 3 Expanded state
1 shows an example of the symbol sheet. On the symbol sheet 25
Indicates that a total of 12 symbols are arranged at a constant pitch.
Form a symbol string. One symbol string
Symbol type is "red 7" (shaded
"7"), "Yellow 7" (white "7"), "Red BAR"
(“BAR” with diagonal lines), “White BAR” (white outline)
"BAR"), "blue BAR" (dotted "BA"
R ") and" Cherry ". The sign
25a is a symbol sheet 25 wound around the reel body.
Shows the attachment margin when attaching and fixing. Regarding the symbol sheet of each reel,
Jerry "and one of" Red 7 "are common to all
In the embodiment, “Cherry” is an array per symbol row.
Corresponds to the large number of first symbols, "Red 7" is the number of arrays
Is one of the symbols with less number. Also, "Yellow
7 "," Red BAR "," Blue BAR "," Yellow BAR "
Although it is changed in the range of 1 to 2 for each reel,
Symbols with a smaller number of sequences compared to "Cherry"
Hit. Therefore, the total number of symbols per reel
In the simple probability determined by the number of types and “red BAR”, “red BAR” is 1
/ 12, "Cherry" is 5/12, and other thin
Bol is different for each reel. Winning a prize is 3 reels
Is determined by the combination of symbols for each
Simple probability that the "Red 7" symbol will be on the winning line of the book
Is (1/12) ^Three , "Cherry" has a probability of (5/1
2) ^Three It becomes. It should be noted that systems other than "Red 7" and "Cherry"
The simple probability that the symbols are aligned on one winning line is
Depends on how many symbols are arranged on each reel.
But (1/12) ^Three Larger than (2/12) ^Three Than
Is small. In this slot machine, the same type of symbol
Besides the winning line, the same pattern with a different color
Even if the symbols are completed, a prize will be won. That is, “7-7-
7 "and" BAR-BAR-BAR "also win. One case
In order to win these prizes, the following
Are paid out. (1) When the number of inserted medals is 8 or less
(Per winning line) 200 "red 7-red 7-red 7" 200 "yellow 7-yellow 7-yellow 7" 80 "7-7-7" 8 "red BAR-red BAR-red BAR" 20 "White BAR-White BAR-White BAR" 15 "Blue BAR-Blue BAR-Blue BAR" 10 "BAR-BAR-BAR" 4 "Cherry-Cherry-Cherry" 3 (2) When the number of inserted cards is 10 (a) Is the symbol of the same pattern aligned in all display windows?
If all the winning lines are
This is done. (B) "7" or "BA" is displayed on all display windows.
When the "R" pattern is complete, it depends on the type of symbol
The following number of payout medals will be paid out. [ALL red 7] 10000 sheets [ALL yellow 7] 5000 sheets [ALL 7] 500 sheets [ALL (red or white or blue) BAR] 150 sheets [ALL BAR] 50 sheets (c) Special when "Cherry" is available
A prize will be won and the sub game will be started, which will be described later.
Depending on the outcome, the number of payout medals shown in (b) above will be paid out
It is. "Cherry" appears on all of the display windows 3.
And a chime (not shown) sounds and the secondary game automatically starts
Be executed. The sub-game is the display window 3 of 3 rows and 3 columns
One reel rotates only behind the central display window 3a
This is done by letting The rotation of this reel
When the symbol column is moved and displayed, it stops
The symbol of the secondary game is determined by the symbol that appears in
You. The symbol of the sub game determined in this way is "Red 7"
, Each resource behind the remaining eight display windows 3
Are rotated all at once, displaying "Red 7" and stopping
You. And payout of 10,000 payout medals
Is Similarly, depending on the sub game, "yellow 7", "red 7"
"BAR", "White BAR", "Blue BAR" are the display windows at the center.
When it appears at 3, the remaining eight reels spin again
Stop control so that the same type of symbol appears
The payout medals of the number shown in (b) above are paid out.
It is. In the sub game, "CELLI" is displayed on the central display window 3a.
The stop position control of the reel so that the symbol
Done. The flowcharts of FIGS. 4 and 5 will be described below.
Accordingly, the operation of the above slot machine will be described.
If you start the game with 1 to 8 medals
By operating the start lever 12, nine reels
These reels rotate all at once and at random timing
Is stopped. Shin appearing behind each of the display windows 3
The combination of bols is determined by the number of inserted medals.
Judgment is made according to the entire activated winning line. Soshi
If the prize shown in (1) above has been obtained,
Line indicator 7 provided for the winning line
Switches from a continuous lighting state to a slow blinking state.
You. This allows the player to win any winning line
You can see at a glance whether it has been done. Also, CPU
10 drives the medal dispenser 18 and selects the type of the prize.
The payout medals corresponding to the number are paid out to the tray 20. After ten medals have been inserted, the game is started.
In this case, the display window is displayed in step 1 (ST1) of FIG.
It is determined whether the same pattern of symbols has stopped in all three.
Is determined. When this determination is N (No),
The same as when 8 dulls are inserted,
To determine if there is a prize, and if a prize has been obtained
Pays out the number of payout medals corresponding to the type of winning
Is done. As a result of the determination in ST1, Y (Yes)
Therefore, all of the display windows 3 have symbol patterns other than "Cherry".
When the turns are completed, the winning prize shown in (2)-(b) above
It is determined which one of them is, and all the line indicators 7
It blinks in a clear cycle to show that a prize has occurred.
Display, and the number of payout medals corresponding to the type of winning
Will be paid out. In particular, the "ALL red 7" prize was obtained
10000 payout medals will be paid out
Winning prize, blinking display on the line display 7
In addition, a chime sounds and appeals to the surroundings. "ALL Cherry" by ST2
If a winning is identified, a special prize is won and the processing shown in FIG.
The sub game is started according to the principle. Vice game starts
Then, all of the line indications 4 are displayed in a short cycle of about 0.5 seconds.
Flashes at the end of the period, and the chime triggers a jackpot
When the secondary game started with a different pattern from the birth
And appeal to the surroundings. At the same time, nine display windows 3
Only the reel provided behind the central display window 3a
Start rotation. When the sub game is started, the CPU 10
Sample one random value from the stored random number generator
The type of winning in the secondary game is determined according to the value,
The symbol of the sub game is determined. At this time,
Bol is determined from symbols other than "Cherry"
You. The symbol determined in this way was "Red 7"
Then, the CPU 10 displays after a random time has elapsed.
Stop the reels so that the "red 7" symbol appears in the window 3a.
Perform stop control. As already mentioned, the spinning reel
The rotational position of is determined by the total of the corresponding counter in the winning determination unit 16.
The CPU 10 monitors this count value.
To supply drive pulse to motor driver 15 while
Stepping so that "red 7" appears in the display window 3a
The stop position of the motor is determined. In this manner, the "red 7" is displayed on the central display window 3a.
When the symbol stops, this “Red 7” is decided in the secondary game.
Symbol. The symbol for the secondary game is determined
Then, the remaining eight reels start rotating simultaneously. Soshi
In addition, the CPU 10 controls each of the counters built in the winning determination unit 16.
While monitoring the count value of the data, "Red 7" is displayed on each display window 3.
Stop each stepping motor so that the symbol of appears
Perform control. Therefore, all of the nine display windows
The symbol “red 7” determined by the system appears. When all the reels stop in this way, a big hit
Winning, big by line indicator 7 and chime
Winning prize is displayed and 10,000 payout medals
Will be paid out. Note that the game determined by the sub game
When the symbol is another, the same symbol
Will be displayed on all of the display windows 3, and the winning
Payout of the number of payout medals according to the type of the payout medal is performed. Originally, "A", which has the largest number of payout medals,
The probability of winning of "LL Red 7" is determined by the
Obtained by simple probability calculation only from the number of "Red 7" symbols
If you do, (1/12) ⁹ It ’s one in five billion
Smaller. Therefore, "ALL red 7" prize
Is a prize that rarely occurs in probability
It greatly reduces the interest of the player. Conversely, I mentioned above
Just use random number sampling techniques to stop the reels.
If you perform stop control and generate this prize at an appropriate frequency,
From the above probability, it becomes extremely unnatural. Therefore, as described above, the distribution per reel is
"Red 7", "Yellow 7", "Red BAR",
For “White BAR” and “Blue BAR” symbols,
The probability that they are aligned with all display windows 3 is extremely low.
Considering these, the number of arrays per reel is
Many "cherry" symbols are displayed on all display windows 3
Occasionally a sub game is started, and "ALL red 7", "A
"LL Yellow 7", "ALL Red BAR", "ALL White BA"
R ”and“ ALL blue BAR ”at appropriate frequency
You. The simple probability of obtaining "ALL cherry" is (5 /
12) ⁹ Is greater than 1/2700
In the result of the above sub game, "ALL red 7"
Generate prizes that rarely occur in probability
A reasonable frequency without giving the player unnatural feelings
It is possible to generate these prizes. In the case of the above embodiment, when a special prize is won,
Rotate only one reel behind the central display window 3a
The secondary game starts, but reels are rotated in the secondary game
Are not limited to those behind the central display window 3a,
It may be in a position. Furthermore, the same as the start of the secondary game
Sometimes all reels are rotated all at once, with the center display first
Stop reels behind window 3a or other display window 3
After deciding the symbol of the sub game, the remaining reels
It is also possible to perform stop control in accordance with this. In addition to a single reel, a plurality of
It is also possible to play a sub game using the
When playing the sub game using the reels of
After “Cherry” is displayed on display window 3, all reels are
Rotate so that all symbols are
The stop control of the rule may be performed. In addition, the sub game is played
The first condition is to insert 10 medals
However, the present invention is not necessarily limited to this.
It may be the number of sheets. As described above, the reel used in the normal game is
The slot machine by playing the sub game using
Configuration can be simplified, but
Dedicated secondary game device to further enhance the appeal
It is also possible to add. For example, slot machine
A dedicated display window for the secondary game is provided on the front panel of
"Red 7", "Yellow 7", "Red BAR", "White BAR",
Spin the reel on which the "blue BAR" symbols are arranged
In the sub game, the symbol is
After the reels are determined, the reels behind each display window 3 are driven to
Stop system so that symbols determined in the game appear
You can do it. In addition, a reel dedicated to the sub game is used.
Instead, a flashing roulette wheel on the front panel
With a roaming game machine.
One of the above five types of symbols
You may. In practicing the present invention,
Various modifications are possible. For example, by winning a jackpot
Instead of paying out 10,000 payout medals as a bonus
In addition, during a certain number of successive games,
Games with a higher probability of winning than regular games
You can give bonus game bonus that can
No. Furthermore, slot machines built into pachinko machines
For gaming machines of the form
The pachinko machine is equipped with an award
Release the tacker and snap it for a certain period of time or a certain number.
Combining techniques such as keeping the ball easy to win
Can be Other thin machines used in slot machines
Even for the types of bolts, various patterns or coloring
Symbol, or a symbol per symbol row.
The total number and types of cards can be changed as appropriate, and the number of payout medals
Of course, the present invention is not limited to the above. Further
In addition, the present invention is incorporated in other game machines such as pachinko machines.
Video-type slot machines
Window and reel with 3 rows and 3 columns or more
Can also be used. Also, in the normal game, the reels are
To stop sequentially while shifting the ring
Is a special winning reel before stopping the last one
Status, that is, all reels that have been stopped so far are special
If it is a symbol that constitutes a prize,
Shake the reel or rotating reel in small increments,
Flipping, or even changing the reel lighting,
For video type, modulated to symbol color and brightness
To indicate that you have reached your reach.
Is also effective in raising interest. In addition, if a special prize is obtained
It is also possible to give these changes when
is there. Further, the present invention omits the above-mentioned sub game.
The present invention can also be practiced in such a form. For example, in the above embodiment,
And display the result of playing the game by inserting 10 medals
When "Cherry" is in all of window 3, this is specially inserted.
Prize, then automatically re-spin the reels
Reel stop control so that "red 7" appears in display window 3
I do. Therefore, in effect, "ALL Cherry"
Is the same value as "ALL Red 7",
When "ALL Cherry" is displayed,
No medals will be paid out. And "A
LL Cherry ”special prize
After the 7 or chime is displayed, all reels are automatically
Rotation is resumed, and all of these display “Red 7” on the display window 3.
When it stops and shows, it will be a jackpot prize,
The display is done and 10,000 medals are paid out
You. According to the above configuration, the simple probability is almost impossible.
"ALL red 7" jackpot prize that never occurs
"CELLI" which is arranged 5 pieces per reel
Probability that "-" is aligned with all display windows 3 (5/12) ⁹ Occurs in
Will be able to do that. Therefore, an appropriate frequency
After generating "ALL cherry" at the degree, "ALL red"
By generating a "7" jackpot prize, the player
Generate a jackpot prize without discomfort
Can give players the expectation of winning a jackpot
Can be In the above embodiment, one reel
As the first symbol with a large number of symbols
And the second synth with a smaller number of
"Red 7" is used as the bolt, but the symbol itself
The pattern, color, etc. can be changed to various other
You. Also, when all of the display windows 3 are aligned, a big hit prize
1 to 2 per reel
It is usual to keep individual, but the first that constitutes a special prize
The number of symbols per reel and the number of symbols per reel
Payout rate for the number of all symbols
Can be appropriately changed in consideration of the above. As described above, according to the present invention, the thin
From the number and total number of symbols included in the column
To generate a prize with a very low probability of occurrence
In this case, the first thin
In response to Bol appearing in all display windows,
The symbol row is moved and displayed again behind the display window of
The second symbol with a smaller number of arrays than the symbol is displayed
Because it appears in all of
Low prizes, without giving the player unnatural feelings
Can be generated at an appropriate frequency. Moreover,
By performing such processing, this prize is obtained
When a symbol is
Appear simultaneously on all display windows arranged in multiple rows and multiple columns
Therefore, it has a high degree of appeal to players, and slot machines
Or the game is played in the form of a slot machine game
