Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a reel-type game machine typified by a slot machine. More specifically, the present invention relates to a reel-type game machine that allows you to play more interestingly.

[Prior Art] A reel-type game machine such as a slot machine usually uses three symbol reels each having a large number of symbols on its circumferential surface, and rotates them so that one symbol is placed on each symbol reel.
When the player presses the stop button provided individually, each symbol reel is stopped at random, winnings are determined according to the combination of symbols on the predetermined winning line, and if a prize is won, This is a game machine that pays out a predetermined number of medals.

10 and 11 show a schematic front view of such a conventional reel-type game machine Z, a winning line on the front panel 21, a symbol drum, etc. as seen from the reel window.

The reel-type game machine Z has a box-shaped housing, and inside thereof, three pattern reels 1, 2, 3, a motor for rotating them, and other control equipment are built-in. There is. On the outer peripheral surface of each of the pattern reels 1, 2, and 3, for example, 21 patterns of 7 types are displayed in a random arrangement order. In addition, the front panel 21 at the upper front includes a reel window 22 for the player to see through the symbols on the symbol reels 1, 2, and 3, and a reel window 22 for the player to see through the symbols on the symbol reels 1, 2, and 3.
Start switch 1 for rotating 2 and 3
0. stop buttons 11, 12, 13 for individually stopping the rotation of each of the symbol reels 1, 2, 3;
A medal slot 9 and a line display 23 for displaying the position and number of winning lines are provided.

In such a game machine Z, the winning line is in the reel window 2.
Five symbols are prepared corresponding to the symbols in the three rows of symbol reels 1, 2, and 3 that appear on reel 7, and from among these, the winning line at a predetermined position and number is mechanically selected according to the number of medals inserted. It is becoming more and more common. In other words, if the number of medals inserted by the player into the medal slot 9 is one, only the center line will be displayed, and if the number of medals inserted by the player is two, then there will be three lines in which the upper and lower lines a and b are added to the center line. However, in the case of three lines, the five lines to which diagonal lines a and b are added become winning lines.

Games on such conventional game machine Z are
As shown in FIG. 12, the game begins with the player inserting medals into the medal slot 9 (201), and the player pressing the start switch 10 to rotate each symbol reel 1, 2, 3 (202). After that, when the stop buttons 11, 12, and 13 are pressed in any order 203, each symbol reel 1, 2, and 3 stops rotating. When all the symbol reels 1, 2, and 3 have stopped (204), winning is determined based on the combination of the stopped symbols on the entered prize line (205), and if the winning has been achieved, a predetermined number of medals are paid out (206). In addition, if no prize is won, the game ends without medals being paid out (hereinafter, such a game will also be referred to as a drum-type game machine according to the present invention).
Due to legal regulations, the number of medals that can be paid out per game is limited, so when you get a big win (a combination of symbols that is extremely difficult to match), instead of paying out a large amount of medals at once, A small game with one reel that is likely to win is played many times in a row, giving a large return to the player (giving one large prize, so to speak).
Some games are equipped with a so-called continuous yakubutsu game (bonus game) that aims to achieve this goal. Such a continuous yakuza game is played in a different frame, so to speak, apart from the flow of the normal game after the medals are paid out in the normal game. Furthermore, even in such continuous yakuza games, there is a legal limit on the number of times that can be played in a row, and usually the maximum number of times within the limit is played, but the number of small games that can be played on one reel is Another game has been proposed that allows the decision to be made using another game (Japanese Utility Model Publication No. 37380/1983).

[Problems to be Solved by the Invention] In the conventional game machine Z, the stop position of the symbol reel is a combination of a chance element and a player's technique of aiming and pressing the stop button. It is widely used as a game machine that allows you to play fun games.

However, the inventor of the present invention was conducting intensive research into a game machine that could play even more interesting games.
We discovered that an even more interesting game could be created by allowing a special game to be played after the normal game, and when a player wins, the winning medals in the normal game are doubled and paid out.

The present invention provides a new drum-type game machine completed based on this knowledge.

[Means for Solving the Problems] The reel type game machine of the present invention will be explained based on FIG. 1.

The present invention provides at least three pattern reels 1, 2, 3 on which a suitable number of different types of patterns are displayed on a circumferential surface.

A normal game determining means 31 which determines whether or not a prize has been won based on the detection signals 5, 16, and 17, calculates the winning score in the case of a prize, and allows transition to a doubling game; A second stopping means 29 gives a stop signal to the winning/failure determining device 10 by human operation, and determines whether the result of the winning/failure determining device 10 when h is stopped is "hit" or "miss", ” or a “miss” decision signal, and i memorize the winning score in the normal game or the previous doubling game, and when a “win” decision signal of the doubling game decision device is input. , the entered prize score is doubled, the transition to the next doubling game is allowed on the condition that the previously won score does not exceed the limit value, and the winning score is set to 0 or a low score when a "losing" determination signal is input. a score calculation means 56 for changing to;
j, and a hopper driving means 33 for driving a hopper to pay out the number of medals corresponding to the winning score.

[Function] In the present invention, the first drive devices 5, 6, and 7
When the picture reels 1, 2, and 3 of the book are rotated, and then the first drive device 11, 12, and 13 is manually operated, the three picture reels 1, 2, and 3 stop at the rotational position corresponding to the time of the operation. do.

When the symbol reels 1, 2, and 3 stop, the respective rotation stop positions are determined by the first detection devices 15, 1.
6 and 17 are both detected.

As described above, when one normal game is completed, the normal game determining means 31 detects the stopped symbols on each symbol reel 1, 2, and 3 based on the stop signals from the first detection devices 15, 16, and 17. , it is determined whether the combination is related to winning a prize, and if it is a winning combination, a winning score is calculated and stored. Then, the win/fail deciding device 10 operates and uses the entered prize score as a starting point to award 1
You can try the doubling game for the second time.

When the second stopping means 29 is manually operated, the success/failure determining device 10 stops its operation, displays "hit" or "miss" in accordance with the stopping point, and stops. When it is a "win", it is determined by the doubling game determining means 32, and a determination signal indicating a "win" is issued.

If you win in the doubling game, the winning score of the normal game or the previous doubling game is doubled by the score calculation means and stored, and you are given the right to challenge the next doubling game. Depending on the player's choice, the player can move on to the next game or end the game, but the player can repeat the doubling game as many times as he or she wants until the memorized winning score exceeds the limit (for example, 100 coins). I can take on challenges.

When the winning score exceeds the limit value, the number of medals corresponding to the stored winning score is paid out through the hopper driving means 33.

When a player loses in a doubling game, the winning score of the normal game or the previous stage's doubling game is set to 0 or greatly reduced by the score calculation means, and the game is over.

If you do not win in the regular game, the game will be over.

In the present invention, the doubling game provides the player with a chance to double the winning score in a game-like manner, making it possible to play a game with a lot of fun.

A stop lamp 25, etc., which turns off when 13 is pressed, is provided.

Next, the electric circuits of each of the game machines will be explained based on FIG. 30 is a microcomputer that controls the entire slot machine. The microcomputer 30 includes a CPU that performs comparisons and calculations necessary for the progress of the game based on input signals, and outputs the results as control signals;
Programs that determine procedures such as comparisons and calculations in the CPU, their execution order, etc., ROM that stores various data necessary for determining winnings in normal games and multiplication games, RAM that stores other data, external signals Input port 36 for adjusting the timing of internal signals and selecting input/output signals

2, 13, 14, 29, position detection sensor 15, 1
6, 17, 18, and the signal lines of the medal detector 41 are connected to each other. In addition, each stop button 11,
A stop circuit 48 is interposed in the signal lines 12, 13, 14, and 29. The position detection sensor 1
Numerals 5, 16, and 17 detect a reset signal section provided at one location on the circumference of each symbol reel 1, 2, and 3, and are composed of, for example, a photo sensor. A reset signal is generated once every rotation. The position detection sensor 18 detects a reset signal section provided at one location on the disk 4, and is composed of, for example, a photo sensor, and is configured to emit a reset signal once every rotation of the disk 4. There is.

The medal detector 41 detects that a medal has been inserted into the medal slot 9, and uses a micro switch, a photo sensor, or the like.

The output port 37 has a hopper 42 that pays out winning payout medals, a disk 4 and pattern reels 1, 2,
A speaker 43 that plays a melody with a different tone during the rotation of 3 or when winning a prize, and a score display 5

4, 45, and 46.

Next, this embodiment will be described with reference to FIG. 4.

In this embodiment, when the power is on, a control signal is always issued from the CPU to the stepping motor 4, and the disk 4 is rotated at a relatively high speed 101. Note that the rotation of the disk 4 at this time is used as a preparation for determining the validity of the doubling game.

When a player inserts one medal into the medal slot 9 (102), the detection signal is sent to the medal detector 41.
is sent to the CPU. At that point, the CPU stops sending the drive signal to the stepping motor 4 and issues a drive signal to the stepping motors 5, 6, and 7. Therefore, the disk 4 stops rotating (103), and the symbol reels 1, 2, and 3 start rotating (104). At this time, the disc score determined by the stop position of the disc 4 is displayed on the score display 57 (104).

Detection and display of the number of disk points is performed as follows. Among the reset signals input from the position detection sensor 18 every rotation of the disk 4, the CPU starts from the time when the final reset signal is input.
The number of pulses of the drive signal until the transmission of the drive signal to the stepping motor 8 is stopped is counted. Since the number of drive signal pulses required to rotate one frame of the disk 4 is known in advance, it is determined which frame of the disk 4 is stopped at the target 28 position based on the count pulse number. The correspondence between the number of frames and the number of disk points is also known in advance, and is stored as reference data in a predetermined area of the ROM. Therefore, by comparing the count pulse number as an index with the reference data, the number of disk points appearing at the target 28 position is detected. The disk score detected in this way is temporarily stored in the RAM for the doubling game to be executed later, and a control signal is sent to the score display 57 to display the number, and the score is displayed. 104 displayed on top of the container 57.

In this way, if "1" on the disk 4 has stopped at the position of the target 28, it will give 1 point, if "2" has stopped, it will give 2 points, and in the case of "3" and "4", the same goes. 3 points and 4 points are displayed on the score display 57.

The normal game starts when the symbol reels 1, 2, and 3 start rotating. After that, when the player presses the stop buttons 11, 12, and 13 arbitrarily (105), a stop signal is imported into the CPU.
The drive signals directed from the CPU to the stepping motors 5, 6, and 7 are stopped. Therefore, the rotation of the symbol reels 1, 2, and 3 is stopped 106. The stepping motors 5, 6, and 7 rotate and stop in quick response to the drive signal, so they stop almost instantly when the player presses a button.

Therefore, the player must press each stop button 11, 12,
By freely selecting the order and interval of pressing 13, it is possible to stop each of the symbol reels 1, 2, and 3 at desired positions. Picture reel 1, 2,
When all 3 are stopped (106), the normal game ends, winning is determined based on the combination of the stopped symbols at that time (107), and winning points are displayed according to the type of winning.

The normal game determining means 31 that executes the determination and display is comprised of a microcomputer 30, and is performed as follows. The CPU detects each symbol reel 1, 2 from the position detection sensor 15, 16, 17.
From the time when the final reset signal is input among the reset signals input every rotation of step 3 until the stop signal is input and the transmission of drive signals to each stepping motor 5, 6, and 7 is stopped. Count the number of pulses of the drive signal between. Each symbol reel 1,
The number of pulses of the drive signal required to rotate one frame of the symbols appearing in 2 and 3 is known in advance, so depending on the count pulse number, which frame of each symbol reel 1, 2, and 3 will be displayed in the reel window. 22, and it is determined whether the vehicle is stopped or not. In order to determine winning, several combinations of symbols related to winning are stored in a predetermined area of the ROM.
The CPU uses the count pulse numbers for the three pattern reels 1, 2, and 3 as an index to compare the pattern combinations in the ROM. If the comparison results match, it means a prize, and the type of prize is also determined at the same time. Then, a drive signal is outputted to the winning score display 58 to display the winning score corresponding to the winning type. In addition, some game machines provide a chance to re-spin specific symbol reels 1, 2, and 3 108 and receive a winning determination again if you do not win a prize, or if you win a prize but your winning score is low. In the case of such a game machine, a definitive winning determination and winning score are displayed based on the stopped symbols when the rotation is prevented after re-spinning (109).

The lamps 51 and 52 constitute the validity determining device 10 together with the disk 4.
On the surface of the lamp 52, the odd numbers "1" and "3" of the disk points are displayed, and on the surface of the lamp 52, the even numbers "2" and "4" of the disk points are displayed. Note that instead of the numbers, patterns of human faces with different expressions may be displayed.

These lamps 51 and 52 are designed to start blinking alternately at the same time when a prize is won in the normal game.

In other words, a double game can be played following the normal game. Therefore, the CPU stops the drive signals to the stepping motors 5, 6, and 7, and simultaneously issues lighting signals to the lamps 51 and 52 alternately. After the lamps 51 and 52 start blinking alternately, the player presses the stop button 2.
When you press 9, it's 110, and that stop signal is the CPU
be taken in. As a result, the CPU stopped blinking control, and the light was on when the stop operation was performed.
Only one of the lamps 51 or 52 is turned on, and the other lamp 51 or 52 is turned off.

At this time, if the lamp 51 displaying an odd number is lit, if the number on the disk 4 that is stopped at the target 28 position is "1" or "3", it is a "win" and so on. Otherwise, it will be "missed". Also, if the lamp 52 with an even number is lit, the target 28
The number on disk 4 that is stopped at the position is "2"
Or, if it is "4", it is a "hit", otherwise it is a "miss". This determination of validity is determined by the doubling game determining means 32, which is realized by comparative determination by the microcomputer 30. Note that since the score calculation means 56 and the hopper driving means 33 are also constituted by the microcomputer 30, their processing procedures will be explained.

The CPU detects the number of disk points detected earlier (1 to 1).
4) from RAM and determine whether it is odd or even. Next, it is determined whether the lit lamp is the lamp 51 displaying an odd number or the lamp 52 displaying an even number, and the two are compared and if both are odd numbers, or both are even numbers. In this case, a determination signal 111 is issued which means a "win" in the doubling game.

When such a decision signal is issued, the CPU takes the next step to calculate the winning score11.
2. This is done by first calling up the winning score stored in the RAM (the one that was stored when symbol reels 1, 2, and 3 stopped) and then executing an operation to double it. Furthermore, you can challenge the doubling game as many times as you like until your winning score exceeds the limit.

When the double prize winning score is obtained in this way, a drive signal is issued to the hopper 42 to pay out the number of medals corresponding to the score. As a result, medals as winning dividends are awarded to the player, and the game is over.

The contents of the doubling game described above form the basis of the present invention. That is, in FIG. 4, the steps after step 109 show a rather simple form, and the game machine of the more preferred embodiment is capable of executing more complicated game contents. One example will be explained based on FIG. Note that FIG. 5 shows only steps after step 110 in FIG. 4. That is, the contents before step 112 are the same as shown in FIG. To put it very simply, this content is the addition of a first special game for paying out winning dividend medals, and a second special game for accumulating points for low dividends if you do not win a prize. There is.

If you get a "win" in the doubling game, it will be 111, and if the winning score is doubled, it will be 112, and the doubled winning score will be
113 is added by the CPU until it reaches 100 points. At the same time, in order to display the added score on the added score display 59, a display signal is issued from the CPU to the display 59. The player can play the doubling game any number of times until the added score reaches 100 points114. Note that even if the score does not reach 100 points, if the player presses the stop button 14, the game may immediately proceed to the first special game. The doubling game here is that if you lose,
Since the payout is set to be reduced as will be described later, the player is faced with highs and lows every time he plays the doubling game.

If the above added score reaches 100 points, the CPU
issues a drive signal to the stepping motor 18 in order to shift to the first special game. As a result, disk 4 begins to rotate at a low speed 115. In this first special game, as disk 4 rotates,
If the moving mark M, which moves toward and away from the target 28, is successfully stopped at the target 28 position, it will be a "hit", and the disk 4 will be stopped by pressing the stop button 14 by the player. The rotation of the disk 4 is set at a low speed, and by pressing the stop button 14 while keeping an eye on the moving mark M, the rotation can be successfully stopped at the target 28 position in most cases.

If the player now presses the stop button 116, the stop signal will be taken into the CPU,
Immediately, the drive signal from the CPU is stopped, and the rotation of the disk 4 is stopped. As a result, whether the moving mark M has stopped at the target 28 position is determined as follows. It was explained earlier that the reset signal is sent to the CPU from the position sensor 18. The stop position of the moving mark M can also be determined by counting the number of drive pulses after receiving the reset signal, in the same way as the stop position of the number of disk points. Therefore
By determining whether the number of pulses counted by the CPU matches the number of pulses when the moving mark M stops at the target 28 position, it is determined whether the first special game is valid or not.

If the thus determined result is a "win" (117), the CPU issues a drive signal to the hopper 42 to pay out 100 winning payout medals, and then the game is over (119). Note that if the determination is "miss", the game is over (119) without receiving any medals.

Next, we will explain what happens when you do not win in the normal game. If the player does not win in the normal game, this means that the determination in step 107 in FIG. be done. Note that if the player is "missed" in the doubling game shown in step 111 of FIG. 5, the second special game is also played. The second special game executed here is intended to give the player a chance to get a low payout score even if he loses in the normal game or doubling game.

If the judgment results in step 107 and step 111 are "off", the CPU issues a drive signal to the stepping motor 8, and the subsequent stop operation 121 and propriety judgment 122 are carried out in steps 116 and 117. It is done in the same way. If the judgment result in step 122 is a "win", the disk points are added up by the CPU 123 until they reach 10 points. Note that the disk score is determined in step 103 in FIG.
This is the score from 1 to 4 that was displayed 107 on the score display 57. When the added points reach 10 points or more, a drive signal is issued from the CPU to the hopper 42, and one medal is paid out for every 10 points125. In the second special game, the number of medals paid out is one for every 10 points, and the payout ratio is reduced to 1/10 compared to the first special game, where points and medals are paid out on a one-to-one basis.

Regarding the game content of this example as described above,
Its characteristics will be explained based on FIGS. 4 and 5. After the player enjoys the normal game shown up to step 106 in FIG. 4, the player receives a prize determination 107.
If you win in the regular game, step 1 in Figure 5.
Doubling games shown in 10-113 may be performed. Here you can experience the excitement of whether your winning score will be doubled or drastically reduced. Even in the doubling game, if you win, you will be given a chance to get double the amount of dividend medals. Then the first
Even in the special game (steps 115 to 118), if the player wins, dividend medals are paid out and the player can obtain them.

On the other hand, when the player does not win in the normal game or "loses" in the doubling game, a second special game in steps 120 to 125 can be executed. In this second special game, you cannot immediately get the dividend medals, but if you get "wins" several times and accumulate points, you can receive medal dividends at a small rate.

As described above, the game content of this embodiment has the great pleasure of doubling the winning payout, and is even more enjoyable due to the payout and the accumulated payout in case the player does not win.

Embodiment 2 In the present invention, the propriety determining device 10 can be of any type as long as it can determine propriety with a simple switch operation. Another example of the configuration of the validity determining device 10 will be described next.

In FIG. 6, 61 and 62 are lamps,
The two lamps 61 and 62 are designed to blink alternately in response to a control signal from the microcomputer 30. Switches 63 and 64 are provided in association with the two lamps 61 and 62, respectively.

The player can freely select and press either switch 63 or 64, and when the switch 63 or 64 is pressed, the lamp 61 or 62 associated with that switch 63 or 64 will light up. If it lights up, it is considered a "win". A “hit” is determined at the moment when the lighting signal to the microcomputer 30 is issued.
This is done by determining whether the corresponding switch ON signal is input.

Embodiment 3 The validity determining device 10 shown in FIG. 7 uses a 7-segment numeric display 65.
The numbers are sequentially and repeatedly displayed by a control signal from the microcomputer 30. The display is stopped by pressing one of the two switches 63, 64. When the switch 63 is pressed, if the stop display is an odd number, it is a "hit", otherwise it is a "miss", and when the switch 64 is pressed, if the stop display is an even number, it is a "hit",
Otherwise, it is considered a "miss". The "win" determination is also performed by the microcomputer 30.

Embodiment 4 The validity determining device 10 shown in FIG.
You can stop it by pressing . When the switch 63 is pressed, if the mark that stops at the position of the arrow 67 on the reel window 22 is ○, it is considered a "hit", otherwise it is considered a "miss", and when the switch 64 is pressed, the reel stops. If the mark you made is an X, it is considered a “hit”, otherwise it is a “miss”.
It is said that

The “hit” judgment is also done by the microcomputer 30.
It is carried out by.

Embodiment 5 In the first embodiment, only one winning line is fixed, but it may be possible to select a plurality of winning lines.

Another such embodiment is shown in FIG. In this embodiment, five winning lines a, b, a, b are displayed on the reel window 22. If the number of medals inserted into the medal slot 9 before the start of the game is one, only one winning line will be selected, and if the number of medals inserted is two, three winning lines, a and b, will be selected. selected,
Further, if there are three medals inserted, control is performed so that five winning lines, a, b, a, b, are selected. Therefore, the winning determination in this embodiment is made for each winning line selected according to the number of medals inserted, and then the game shifts to the doubling game.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit thereof.
