Abstract

<P>PROBLEM TO BE SOLVED: To provide a game machine such as a slot machine, capable of arousing interest in a game. <P>SOLUTION: Display windows 3 are arranged in the from of a 3 by 3 matrix. Reels are rotated behind the display windows. Each reel bears 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' symbol, however, is a somewhat high (5/12)<SP>9</SP>. When all of the display windows 3 are filled with the 'cherry' symbol, the reel behind the display window 3a in the center rotates, providing a subsidiary game. When the reel stops and the 'red 7' symbol is determined, the reels behind the other display windows 3 rotate. The reels are controlled to stop so as to make the 'red 7' symbol appear in the other windows 3, leading to a 'all red 7s' big win, the probability of occurrence of which is very low. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine in which a game is played in a game mode known as a so-called slot machine.

[0002]

2. Description of the Related Art According to Japanese Unexamined Patent Publication No. 8-10383, the display windows of symbols are arranged in a matrix of 3 rows and 3 columns, and the reels on which the symbols are arranged are rotated at the back of each display window. Type slot machines are known. When all reels are stopped, 9 symbols are observed through each display window. With respect to these symbols, a combination of symbols referred to in winning determination is generally set in advance by a total of eight winning lines of three horizontal lines, three vertical lines and two diagonal lines. Since the nine symbols are determined by the respective stop positions of the individual reels, in addition to the above eight pay lines, it is possible to further increase the pay lines such as a combination of four symbols located at the corners. .

Further, since nine reels are used in the slot machine, the same symbol may appear in all display windows. Such a symbol display form is unique and cannot be obtained by the conventional 3-reel type display, and has a very high appeal to the player. Taking advantage of these features, when all the display windows have the specific symbols that pay out the most medals when aligned on the normal winning line, this is set as the highest-level winning (big hit prize). Is normal. Then, when the jackpot prize is obtained, for example, 10,000 medals are paid out, or the right of the bonus game that the game can be executed in a state where the probability of occurrence of the prize is high for a predetermined number of times is obtained. Is given a great privilege.

[0004]

By the way, in the case of the 9-reel type slot machine, the number of symbols per reel is about 10 because each reel cannot be made too large. If one specific symbol is provided for each reel, the probability that it will appear in all display windows is 1/10 ⁹ (one billionth). This is almost a hopeless probability for the player, and cannot give the expectation for the jackpot winning.
In addition, most of the recent slot machines use a microcomputer to control the probability of winning, and it is possible to generate a jackpot at an arbitrary probability. However, when the jackpot is generated by the microcomputer at an appropriate frequency, it is clear that the probability of occurrence will be impossible compared with the above probability, and it is inevitable that the player feels unnatural. . For this reason, there was a problem that the interest in playing games such as slot machines decreased.

The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a gaming machine capable of improving the interest in playing games such as slot machines.

The above-mentioned object of the present invention is also common to a video type slot machine which displays a reel image together with a display window on a CRT or a liquid crystal display panel, and a slot incorporated in a pachinko machine as a part of a winning device. It is common to a machine-type game machine and a slot machine-type game machine incorporated as an auxiliary game device for other game machines.

[0007]

In order to achieve the above object, the present invention has a display window of symbols arranged in at least a plurality of rows, and reels having a plurality of kinds of symbols arranged therein are moved and displayed behind the display window. However, when the movement display of each reel is stopped while shifting the timing, the last one reel is stopped in the gaming machine in which the presence or absence and the type of the prize are determined based on the combination of the symbols appearing in each display window. It is characterized in that the reel that has been stopped or the reel that is rotating is swayed in small steps when the special winning reach state is reached before the game is played.

Here, as in claim 2, when the last one reel is in the special winning reach state before the stop, the illumination of the stopped reel or the spinning reel is changed. be able to.

Further, as in claim 3, when the last one of the reels is in the reach state of the special winning before the stop, the color and brightness of the stopped reel or the symbol of the spinning reel Can be modulated.

DETAILED DESCRIPTION OF THE INVENTION An embodiment in which the present invention is applied to a slot machine well known as a gaming machine will be described. An outline front view and an electrical configuration of a slot machine using the present invention are shown in FIGS. 1 and 2. The front panel of the game machine body 2 is provided with the symbol display windows 3 arranged in a matrix of 3 rows and 3 columns. Behind each display window 3, reels 5a to 5i having a plurality of kinds of symbols arranged at a constant pitch are provided on the outer periphery, and each of the reels 5a to 5i constitutes a symbol row to be moved and displayed behind the display window 3. . These reels 5a to 5i are stepping motors 6a to 6i.
Can be rotated individually by.

As shown in FIG. 1, three display windows 3 arranged in three rows and three columns are combined by three pay lines each having three horizontal lines, three vertical lines and two diagonal lines. At the time of winning determination, the presence / absence and the type of winning are determined by whether or not the symbols of the same pattern are aligned on these winning lines. An arrow-shaped line indicator 7 is provided at one end of each pay line, and the activated pay line is displayed by lighting an LED incorporated therein.
The number of activated winning lines is determined by the number of medals inserted prior to the start of the game. In addition to the straight pay lines, it is possible to further provide, for example, four display windows at four corners, or a pay line in which four display windows are combined in a diamond shape.

When a medal is inserted from the medal insertion slot 8 prior to the start of the game, the medal sensor 9 detects this and inputs a medal detection signal to the CPU 10. CPU10
Counts the number of inserted medals based on the medal detection signal, and sends a display signal to the display driver 11 accordingly. The display driver 11 selectively drives the LEDs 7a incorporated in the back of each line display 7 based on the display signal from the CPU 10.

When one medal is inserted from the medal insertion slot 8, only one horizontal pay line in the center is activated, and every time two or three coins are inserted, the activated pay line is 2 horizontal. The number of books will increase to 3 horizontally. Similarly, when 4 to 6 coins are thrown in, in addition to the horizontal 3 pay lines, the vertical pay lines are increased one by one, and by inserting 8 coins, all the prize lines are activated. The line display 7 is sequentially turned on in response to the increase in the number of activated lines. In addition,
In this slot machine, a total of 10 medals can be inserted by inserting 2 medals after inserting 8 medals necessary to activate all the pay lines. When a game is played after inserting 10 medals, it is possible to play a sub game when a special prize described later is obtained, as well as a normal game in which the presence or absence of a prize is determined by eight pay lines. Become.

When the start lever 12 is operated after inserting the medal, a start signal is input from the start signal generator 13 to the CPU 10. The CPU 10 activates the motor driver 15 in response to the input of the start signal, so that drive pulses are supplied to the stepping motors 6a to 6i provided for each of the nine reels 5a to 5i. However, when no medals have been inserted, the start signal is ignored and the motor driver 15 is not activated.

The reels 5a to 5i are stepping motors 6
The rotation amount can be identified by the number of drive pulses supplied to the stepping motors 6a to 6i. Therefore, the number of drive pulses supplied to each of the stepping motors 6a to 6i is counted by an individual counter provided in the winning determination unit 16, and the sensor 17 is counted each time the reels 5a to 5i pass the reference position.
If the count value of the corresponding counter is reset by the reset signal obtained from a to 17i, the rotation position within one rotation of the stepping motor can be sequentially monitored.

When activating the motor driver 15, the CPU 10 samples a random number value from a built-in random number generator, and determines what kind of prize is to be given to the currently started normal game. Therefore, ROM22
Stores data that associates random number values with symbol combinations in consideration of the payout rate of the slot machine. Then, the CPU 10 samples a random number value for each activated pay line and determines a symbol for each reel to be combined on each pay line.

On the other hand, it is known in advance how the symbols are arranged from the reference position for each of the reels 5a to 5i, and the comparison data thereof is also written in the ROM 22. By performing the stop control of the stepping motor with reference to the count value, it is possible to stop the reel so that the symbol combinations determined corresponding to the random number values are aligned on a predetermined pay line. Therefore, reel 5a
5i are stopped and controlled by the CPU 10 so that a combination of symbols determined based on sampling of random numbers can be obtained.

The winning determination section 16 receives the data of the activated winning line from the CPU 10, and further, the ROM 2
By referring to the data stored in 2, it is confirmed whether or not a winning is obtained for each activated winning line. When it is confirmed that there is a winning, the CPU outputs a winning signal indicating the type of winning and a line signal indicating the winning line in which the winning is obtained among the activated winning lines.
Input to 10, and if lost, CP the lost signal
Input in U10. It should be noted that when a winning is obtained on a plurality of winning lines at the same time, all winning is valid, and each winning signal and line signal are input to the CPU 10.

When a prize is generated, the CPU 10 inputs a display signal for prize display to the display driver 11.
As a result, the display device 7 corresponding to the winning line for which a winning is obtained displays a winning display pattern, for example, a blinking pattern with a slow cycle of about 1 to 2 seconds. Also,
The medal payout device 18 is driven by referring to the data of the number of payout medals stored in the ROM 22, and the number of payout medals corresponding to the type of winning obtained is paid out to the tray 20. The RAM 21 is used as a memory for temporarily storing various data obtained during the game processing, such as the number of inserted medals, and the ROM 22 includes a sequence program for normal game processing and a sub-program in addition to the data described above. A sequence program for game processing is stored.

The reels 5a to 5i are composed of a reel main body connected to the stepping motors 6a to 6i, and a symbol sheet attached to the outer periphery thereof. On the symbol sheet, a plurality of types of symbols forming a symbol array are written at a constant pitch. FIG. 3 shows an example of the symbol sheet in the expanded state. A total of 12 symbols are arranged on the symbol sheet 25 at a constant pitch, and a symbol array is formed by this. The types of symbols included in one symbol row are “red 7” (“7” with diagonal lines), “yellow 7” (white “7”), and “red BAR”.
(“BAR” with diagonal lines), “White BAR” (white “BAR”), “Blue BAR” (“BA with dots”
R ”) and“ cherry ”in total. In addition, reference numeral 25a indicates a sticking margin when the symbol sheet 25 is wound around the outer circumference of the reel body and fixed.

Regarding the symbol sheets of each reel, 5 pieces of "cherry" and 1 piece of "red 7" are common to all, and in this embodiment, "cherry" has a large number of arrangements per 1 symbol column. “Red 7” corresponds to one of the symbols with a small array number. Also, "yellow 7", "red BAR", "blue BAR", "yellow BAR"
Although it is changed within a range of 1 to 2 for each reel, it corresponds to a symbol having a smaller number of arrays as compared with “cherry”. Therefore, “red BAR” is 1 in the simple probability determined by the total number of symbols and the number of types per reel.
/ 12, "cherry" is 5/12, and other symbols are different for each reel. Winning or winning is determined by the combination of symbols on each of the three reels, so 1
The simple probability that "Red 7" symbols are aligned on the winning line of the book is (1/12) ³ , and the probability that "Cherry" is aligned is (5/1
2) It becomes ³ .

The simple probability that symbols other than "red 7" and "cherry" will be lined up on one pay line varies depending on how many of the symbols are arranged on each reel, but (1/12) greater than ^3, it is smaller than (2/12) ^3. In this slot machine, symbols of the same type are lined up on the pay line, and symbols of the same pattern with different colors are lined up to win the prize. That is, "7-7-
7 "and" BAR-BAR-BAR "will also be awarded. As an example, the following number of payout medals are paid out for these winnings.

(1) When the number of inserted medals is 8 or less (per winning line) "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 pieces "Cherry-Cherry-Cherry" 3 pieces (2) When the number of inserted medals is 10 pieces (a) When the symbols of the same pattern are not aligned on all the display windows, the above (1) is applied to all the pay lines. Will be paid.

(B) "7" or "BA" is displayed on all the display windows.
When the “R” patterns are complete, the following number of payout medals are paid out according to the type of symbol.

“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) All of the display windows When "cherries" are collected, a special prize is awarded and a sub game described later is started, and the number of payout medals shown in (b) above is paid out according to the result of the sub game.

When "cherry" appears in all of the display windows 3, a chime (not shown) sounds and the sub game is automatically executed. The sub game is played by rotating one reel only behind the central display window 3a among the display windows 3 of 3 rows and 3 columns. The rotation of the reels causes the symbol row to be moved and displayed, and the symbols that appear when the reels stop determine the sub game symbols. The symbol of the sub game decided in this way is "Red 7"
If so, all the reels rotate at the same time behind the remaining eight display windows 3 and all “Red 7” is displayed and the reels stop. Then, 10,000 payout medals are paid out.

Similarly, when "yellow 7", "red BAR", "white BAR", and "blue BAR" appear in the central display window 3 by the sub game, the remaining eight reels rotate again. The reel stop control is performed so that the same type of symbol appears, and the number of payout medals shown in (b) above is paid out. In the sub game, reel stop position control is performed so that the "cherry" symbol does not appear in the central display window 3a.

The operation of the slot machine will be described below with reference to the flowcharts of FIGS. 4 and 5.
When the game is started by inserting 1 to 8 medals, 9 reels are simultaneously rotated by the operation of the start lever 12, and these reels are stopped at random timing. The combination of symbols appearing behind each of the display windows 3 is determined according to the activated winning line determined by the number of inserted medals. When the winning shown in (1) above is obtained, the line display 7 provided for the winning line where the winning is obtained.
Changes from a continuous lighting state to a slow blinking state. This allows the player to check at a glance which winning line has won the prize. Also, CPU
The numeral 10 drives the medal payout device 18 to pay out the number of payout medals corresponding to the type of winning to the saucer 20.

When the game is started after inserting 10 medals, it is determined in step 1 (ST1) of FIG. 4 whether the symbols of the same pattern are stopped in all the display windows 3. When this determination is N (No), the presence / absence of a prize is determined for all the pay lines, as in the case of inserting eight medals, and when a prize is obtained, the number of coins corresponding to the type of the prize. Payout medal is paid out.

If the result of determination in ST1 is Y (Yes) and all the display windows 3 have symbol patterns other than "cherry", any of the winnings shown in (2)-(b) above will occur. It is determined whether or not there is any, and all of the line display 7 blinks at a slow cycle to indicate that a winning has occurred, and the number of payout medals corresponding to the type of winning is paid out. In particular, when the winning of "ALL Red 7" is obtained, it is a big winning prize in which 10,000 payout medals are paid out, and besides the blinking display by the line display 7, a chime sounds to appeal to the surroundings.

When it is identified in ST2 that the game has become "ALL Cherry", the special prize is won, and the sub game is started according to the process shown in FIG. When the sub game is started, all of the line display 4 blinks in a short cycle of about 0.5 seconds, and the chime sounds in a pattern different from that at the time of the jackpot win and the sub game is started. Appeal to the surroundings. At the same time, only the reel provided behind the central display window 3a among the nine display windows 3 starts to rotate.

When the sub game is started, the CPU 10 samples one random number value from the built-in random number generator and determines the type of winning of the sub game according to the sampled random number value, thereby determining the symbol of the sub game. The symbol at this time is determined from symbols other than “cherry”. Assuming that the symbol thus determined is "red 7", the CPU 10 controls the reel stop so that the symbol "red 7" appears in the display window 3a after a random time has elapsed. As described above, the rotation position of the spinning reel corresponds to the count value of the corresponding counter in the winning determination unit 16, and the CPU 10 supplies the drive pulse to the motor driver 15 while monitoring this count value. The stop position of the stepping motor is determined so that "red 7" appears in the display window 3a.

When the symbol "red 7" is stopped in the central display window 3a in this manner, this "red 7" becomes the symbol determined in the sub game. When the sub game symbol is determined, the remaining eight reels start spinning all at once. Then, the CPU 10 monitors the count value of each counter built in the winning determination unit 16 and displays “red 7” on each display window 3.
The stop control of each stepping motor is performed so that the symbol of appears. Therefore, the symbol “red 7” determined in the sub game appears in all 9 display windows.

When all the reels are stopped in this way, a big win is won, the big win is displayed by the line display 7 and the chime, and 10,000 payout medals are paid out. If the symbol determined by the sub game is another, the same symbol is displayed on all of the display windows 3, and the payout of the number of payout medals according to the type of the prize is paid out. Be seen.

Originally, "A
The probability of winning LL Red 7 ”is (1/12) ⁹ and is 5 billion minutes when calculated by a simple probability calculation only from the number of“ Red 7 ”symbols in the symbol string. It becomes smaller than 1. Therefore, the winning of "ALL Red 7" is stochastically rarely generated, and greatly detracts from the player's interest. On the contrary, as described above, if the reel stop control is simply performed by using the random number sampling method, and this prize is generated at an appropriate frequency,
From the above probability, it becomes extremely unnatural.

Therefore, as described above, "red 7", "yellow 7", "red BAR", in which the number of arrays per reel is small,
Regarding the “white BAR” and “blue BAR” symbols, the “cherry” symbol having a larger number of arrangements per reel than these is considered in consideration of the extremely low probability that they will be aligned on all the display windows 3. When all the display windows 3 are in place, the sub game is started, and "ALL red 7", "A
LL Yellow 7 ”,“ ALL Red BAR ”,“ ALL White BA
"R" and "ALL blue BAR" are generated at an appropriate frequency. The simple probability of getting "ALL Cherry" is (5 /
12) It becomes ⁹ and is larger than 1/2700. Therefore, if a prize such as "ALL red 7" that rarely occurs in the result of the sub game is generated, it is unnatural for the player. It is possible to generate these prizes at an appropriate frequency without giving a feeling.

In the case of the above embodiment, when a special prize is won, the sub game is started by rotating only one reel behind the central display window 3a, but the reel rotated in the sub game is the central display window 3a. It is not limited to the one behind, but may be in another position. Further, at the same time as the start of the sub game, all the reels are rotated at the same time, first the reels behind the central display window 3a or the other display windows 3 are stopped to determine the sub game symbol, and then the remaining It is also possible to stop control the reels accordingly.

It is also possible to use a plurality of reels instead of one reel to play the sub game. For example, when the sub game is played using all reels, "cherry" is temporarily displayed on all display windows 3. After all are aligned, all reels may be re-rotated and the stop control of all reels may be performed so that the same symbol appears in the display window 3. It should be noted that the first condition under which the sub game is played is to insert 10 medals, but the present invention is not limited to this, and an appropriate number of medals such as 8 or more may be used.

As described above, the configuration of the slot machine can be simplified by playing the sub game using the reels used in the normal game, but in order to further enhance the appeal to the player, a dedicated sub game is used. It is also possible to install a game device side by side. For example, on the front panel of the slot machine, a display window dedicated to the sub game is provided, and behind that, "red 7", "yellow 7", "red BAR", "white BAR",
The reel in which the symbols of "blue BAR" are arranged is rotated, and in the sub game, after the symbols are determined using this dedicated reel, the reels behind each display window 3 are driven to determine the symbols determined in the sub game. The stop control may be performed so that appears. Instead of using the reels dedicated to the sub game, a roulette game machine that blinks electronically may be incorporated in the front panel, and one of the five types of symbols may be determined by the roulette game machine.

Further, various modifications can be made in carrying out the present invention. For example, instead of paying out 10,000 dividend medals as a bonus for a jackpot prize, a bonus game bonus that allows a player to win a prize with a higher probability than a regular game during a certain number of consecutive game periods. May be given. In addition, for slot machine type game machines built into pachinko machines, as an award by jackpot winning, the attacker provided as a winning device on the game side of the pachinko machine is opened, and pachinko balls will be won for a certain period or a certain number. It is possible to combine methods such as keeping the state easy.

In addition, the types of symbols used in the slot machine can be changed to symbols with various patterns or colors, and the total number of symbols per symbol column and the number of types can be changed as appropriate. Of course, the number is not limited to the above. Furthermore, the present invention is equally applicable to video type slot machines, including those incorporated in other game machines such as pachinko machines, and can be used for those having display windows and reels of 3 rows and 3 columns or more. You can

In the normal game, when the reels are sequentially stopped while shifting the timing, the special winning state is reached before the last one is stopped, that is, the reels stopped by then. When all are symbols that make up the special prize, you can sway the reel that is stopped or the reel that is spinning,
It is also effective to increase the excitement by reversing and further changing the lighting of the reel, and displaying the fact that the reach state is reached by modulating the color and brightness of the symbol in the video type Is. It is also possible to give these changes even when a special prize is obtained.

Furthermore, the present invention can be implemented in a mode in which the sub game described above is omitted. For example, in the above-mentioned embodiment, when 10 medals are thrown and the game is played, when all the display windows 3 have "cherry", this is regarded as a special prize, and then the reel is automatically re-rotated. The reel stop control is performed so that "red 7" appears in all display windows 3. Therefore, in essence, "ALL Cherry"
Is the same value as "ALL Red 7",
When the display state is "ALL Cherry", the payout of medals for the jackpot is not yet performed. And "A
After the indicator lamp 7 and chime indicate that there was a special prize for "LL Cherry," all reels automatically restarted, and all of them stopped displaying "Red 7" in the display window 3. When it is done, it becomes a big hit prize, a message to that effect is displayed, and 10,000 medals are paid out.

According to the above configuration, the "ALL Red 7" jackpot prizes, which are rarely generated from the simple probability, are arranged in all the display windows 3 with "cherries" arranged in five reels per reel. It can be generated with probability (5/12) ⁹ . Therefore, by generating the "ALL cherries" at an appropriate frequency and then generating the "ALL Red 7" jackpot prize, it is possible to generate the jackpot prize without giving the player any discomfort. It is possible to give a sense of expectation for jackpot prizes.

In the above embodiment, "cherry" is used as the first symbol having a large number of arranged symbols per reel, and "red 7" is used as the second symbol having a smaller arranged number of symbols. However, the pattern and color of the symbol itself can be changed to various other ones. In addition, for the second symbol which is a big win when all the display windows 3 are aligned, 1-2 reels / reel
Although it is usual to keep the number of individual symbols, the arrangement number of the first symbols constituting the special prize per reel and the arrangement number of all symbols per reel should be changed appropriately in consideration of the payout rate. You can

[0046]

As described above, according to the present invention, the display windows of the symbols are arranged in at least a plurality of rows, and the reels in which a plurality of kinds of symbols are arranged are moved and displayed behind the display windows, respectively, and each reel is displayed. The state before the last one of the reels stops in the gaming machine in which the presence or absence of a prize and the type are determined based on the combination of symbols appearing in each display window when the movement display of the When the reach state of the special prize is reached, the stopped reel or the spinning reel is swayed in small increments, so the appeal to the player when the reach state is reached becomes high, and the slot machine or slot machine It is possible to further enhance the interest of gaming machines in which games are played in the form of games.

In addition, when the last one reel is in the reach state of the special prize before the stop, the reel is stopped, or the reel is stopped or spinning. If the lighting of the reel is changed, the interest of the gaming machine can be further improved. In addition, as in claim 3, when the last one of the reels is in the reach state of the special winning in the state before the stop, in addition to the swing of the reel described above, By adding modulation to the color and brightness of the symbol, it is possible to further enhance the interest of the gaming machine.
