Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine having lottery probability setting means for setting a value of a lottery probability for a plurality of predetermined winning modes to a desired value from a plurality of values.

[0002]

2. Description of the Related Art Conventionally, as this type of gaming machine, for example, there is a slot machine.

In a general slot machine, when a start lever is operated by a player after a medal is inserted, a plurality of reels rotate, and rotation of each reel is stopped by operating a stop button. At this time, when a predetermined combination of symbols is stopped and displayed on the display window, a prize is generated, and the number of medals according to the prize mode is paid out to the player. The winning mode is determined by random number drawing inside the machine. This determination is made according to which section of the winning probability table the random number selected by lottery belongs to. That is, the winning mode of the table section to which the random number belongs belongs to the winning mode determined by the lottery inside the machine, and the hit request flag corresponding to the winning mode is set.

The stop position of the rotating reel is controlled so that a symbol corresponding to the type of the hit request flag is stopped and displayed on the display window. That is, when the stop button is operated, the symbol displayed in the display window is not the symbol corresponding to the winning mode, but the symbol corresponding to the winning mode exists in, for example, four frames of symbols displayed subsequent to the display window. In this case, the symbol corresponding to the winning mode is stopped and displayed in the display window,
Reel control for drawing the symbol is performed.

The value of the lottery probability of each winning mode is determined by a value obtained by dividing the size of the probability lottery data defining the size of the table section of the winning probability table by the size of the entire range of generated random numbers.

[0006] In a slot machine provided with a lottery probability setting means capable of setting the value of the lottery probability to a desired value from among a plurality of values, for example, a slot machine having a lottery probability setting table shown in FIG. Can be set for each combination of the six stages. That is, when the setting is 6, the value of the lottery probability of the big bonus game (BIG), which is the jackpot winning mode, is 1 /
240, the value of the lottery probability of the regular bonus game (REG) in the medium winning prize mode is set to 1/364, and the value of the lottery probability of the bell in the small prize winning mode is set to 1/36.

When the setting is 5, the values of the lottery probabilities of BIG, REG, and Bell are respectively 1/240, 1/399,
It is set to 1/39 combination, and when setting 4 is BI
G, REG, Bell lottery probability values are 1/24 each
0, 1/481, and 1/48 are set.
Similarly, for each of the settings 3 to 1, BIG, REG,
The value of each lottery probability of the bell is set to a combination of values shown in FIG.

With this setting, the so-called machine allocation, which is the ratio of the number of payout medals to the number of medals inserted into the slot machine, is adjusted, and the sales of the slot machine at the game store are managed.

[0009]

However, in the conventional gaming machine described above, the setting of the lottery probability for each winning mode by the lottery probability setting means is performed uniformly for all of a plurality of predetermined winning modes. . For example, in the above-described slot machine, the values of the lottery probabilities of BIG, REG, and Bell are uniformly set as a combination of six levels.

[0010] For this reason, in the conventional gaming machine, there is a limit to the adjustment of the machine split, and therefore, there is a limit to the change given to the game property and the payout. For example, instead of setting the lottery probability of the small hit prize during the general game to prevent the number of medals in hand from being immediately reduced, the lottery probability of the big hit prize is set low, or the small probability during the general game is set. Instead of setting the winning prize lottery probability low and immediately reducing the number of medals in hand, set the jackpot prize lottery probability high and adjust it to payout characteristics such as to make it easy to generate big hit prizes continuously. I can't do that. That is, the payout characteristics of the gaming machine cannot be finely adjusted while the overall medal payout rate is the same.

[0011]

When it has reached, a signal notifying the completion of the medal payout is output to the CPU 31.

The ROM 32 stores, as a sequence program, a procedure of a game process executed in the slot machine 1, and stores a winning probability table, a symbol table, a winning symbol combination table, and the like in a divided manner. I have.

The winning probability table is stored in the sampling circuit 3
7 is used to divide the random numbers extracted in 7 into the respective winning modes, and stores data for partitioning a certain range of random numbers generated by the random number generator 36 into the respective winning modes. Such a winning probability table is configured, for example, as shown in FIG. A1 to a3, b1 to b3, c1 to c in FIG.
3, d1 to d3, e1 to e3, f1 to f3, g1 to g3
Is preset numerical data, and is used when the random number extracted by the sampling circuit 37 is divided into each winning mode. This data is “a1 to g1” when the number of inserted medals is one, “a2 to g2” when the number is two, and 3
In the case of sheets, a combination of the numerical values of “a3 to g3” is used.

These numerical values are usually expressed as “a <b <c <d <e <
f <g ”and the extracted random number is d
If less than a, a small hit prize (small hit) is set. In this case, if less than a, a request flag per “two cherries” is set. When the value is b or more and less than c, a request flag for “plum” is set. When the value is c or more and less than d, a request flag for “bell” is set. If the extracted random number value is equal to or more than d and less than e, a "re-game" request flag is set. If the extracted random number value is equal to or more than e and less than f, a medium winning prize (medium hit) is set, a request flag for “RB (regular bonus)” is set, and the extracted random number value is equal to f.
If the value is less than g, a big hit is won (big hit), and a "BB (big bonus)" hit request flag is set.
If the value is equal to or larger than g, no prize is won.

That is, the winning mode is determined by which numerical range one sampled random number belongs to, and is represented by a hit request flag. here,
The random number generator 36, the sampling circuit 37, the winning probability table, and the microcomputer 30 constitute a winning mode determining unit. As described above, the winning mode determining means determines the winning mode of the game based on the random numbers selected by lottery, and sets a hit request flag according to the determined winning mode.

In the present embodiment, “R” per “BB”
Six types of probability lottery data indicating the size of the division per "B" and "two cherries" are prepared for each of the winning modes, and the winning probabilities of each of the winning modes are individually set to six levels. Can be set to

FIGS. 9, 10 and 11 show specific probability lottery data tables when the number of inserted medals in the winning probability table conceptually shown in FIG. 8 is 3, 2, and 1, respectively. I have. These probability lottery data tables are also R
It is stored in the OM32.

FIG. 9 shows a case where the number of inserted medals is three.
It is a probability lottery data table used when a winning mode is determined by a winning mode determining means. In the data table, probability lottery data for each lottery combination is stored for each gaming state, and 6 lottery combinations for each of the lottery combinations “BB”, “RB”, and “2 cherries” are respectively provided. Various kinds of probability lottery data are prepared, and by setting values 1 to 6 individually, the lottery probabilities of each lottery combination are individually set in six stages as described later.

The probability lottery data gw3 of the lottery role “BB” is
This corresponds to the numerical data g3 when the number of inserted medals in the winning probability table shown in FIG. 8 is three, and can be expressed as gw3 = g3-f3 by using the numerical data of the winning probability table. In the probability lottery data table shown in FIG. 9, the value of the probability lottery data gw3 is set to 52 for the set value 1, 54 for the set value 2, and 57 for the set value 3. .

Further, the probability lottery data f of the lottery combination “RB”
w3 corresponds to the numerical data f3 when the number of inserted medals in the winning probability table is three, and can be expressed as fw3 = f3-e3 using the numerical data of the winning probability table. In the probability lottery data table, the value of the probability lottery data fw3 is 50 when the set value is 1 and 5 when the set value is 2.
In the case of 1, setting value 3, it is set as 53.

The probability lottery data ew3 of the lottery combination "replay" corresponds to the numerical data e3 when the number of inserted medals in the winning probability table is three, and is represented using the numerical data of the winning probability table. And ew3 = e3-d3.
The probability lottery data dw3 of the lottery combination "Bell" corresponds to the numerical data d3 when the number of inserted medals in the winning probability table is three, and when expressed using the numerical data of the winning probability table, dw3 = d3-c3. Can be expressed as The probability lottery data cw3 of the lottery combination "Plum" corresponds to the numerical data c3 when the number of inserted medals in the winning probability table is three, and when expressed using the numerical data of the winning probability table, cw3 = c3-b
It can be expressed as 3. The probability lottery data bw3 of the lottery combination “4 cherries” corresponds to the numerical data b3 when the number of inserted medals in the winning probability table is three, and when expressed using the numerical data of the winning probability table, bw3 = b3 -A3.

Unlike the other lottery combinations, each of these four types of lottery combinations cannot change the value of the probability lottery data depending on the set value and becomes a common value for each set value.

The probability lottery data aw3 of the lottery combination “two cherries” indicates that the number of inserted medals in the winning probability table is three.
It corresponds to the numerical data a3 at the time of a sheet, and when expressed using the numerical data of the winning probability table, aw3 = a3-0 = a3
Becomes The probability lottery data aw3 of the lottery combination “2 cherry” also has the set value 1 to 1 in the same manner as the lottery combinations “BB” and “RB”.
6, setting can be made in six steps, such as 512 for setting value 1, 513 for setting value 2, and 514 for setting value 3.

The probability lottery data in each probability lottery data table shown in FIGS. 10 and 11 can be interpreted in the same manner as described above. The lottery probability value is calculated based on the range of random numbers generated by the random number generator 36 (0 to 1638).
4 divided by 16385).

The game states in the probability lottery data tables shown in FIGS. 9 to 11 are classified into three types: general games, internal hits, and BB general games. Here, the inside win is defined as BB by the winning mode determination means.
Or the RB hit request flag is set, but B
This means a normal game state in which a symbol combination corresponding to a hit of B or RB is not aligned on the activated pay line when each of the reels 3 to 5 is stopped. The winning mode determining means determines the game state at that time and appropriately selects the probability lottery data to be used.

The symbol table stored in the ROM 32 is conceptually shown in FIG. The symbol table is for associating the rotation positions of the reels 3 to 5 with the symbols, and represents a symbol row by symbols. In this symbol table, symbol codes corresponding to the code numbers are stored for each of the reels 3 to 5.
The code numbers are sequentially assigned at a constant rotation pitch of each of the reels 3 to 5 based on the rotation position at which the reset pulse is generated. The symbol code indicates a symbol provided corresponding to each code number.

In the winning symbol combination table,
The symbol code of each winning symbol combination shown in the payout display unit 22, the symbol code of the symbol combination forming the “reach eye” that suggests to the player that the flag of the occurrence of the specific game is established, and each winning is shown. A winning determination code, a winning medal payout number, and the like are stored. This winning symbol combination table is referred to at the time of stop control of the first reel 3, the second reel 4, and the third reel 5, and when performing a winning confirmation after stopping all the reels.

Next, the operation of the gaming machine controlled by the microcomputer 30 in this embodiment will be described.

FIGS. 13 to 15 are flowcharts showing the outline of this game processing.

When the power is turned on to the slot machine 1 by the main switch 72, an internal check is performed, and it is first determined whether or not the ROM 32 is abnormal (FIG. 1).
3, step 171). If there is no abnormality in the ROM 32, next, all output ports of the CPU 31 are initialized (step 172), and then it is determined whether or not a power down error has occurred (step 173). In the case of a power down error, the process returns to step 171. If the error is not a power down error, the CPU 31 is initialized (step 174), and it is determined whether or not the RAM 33 is abnormal (step 175). If there is an abnormality in the ROM 32 or the RAM 33, the display drive circuit 42
Is controlled by the CPU 31, and the error of the ROM and the RAM is displayed on the payout number display section 25 (step 17).
6).

If there is no abnormality in the RAM 33 in step 175, it is then determined whether or not the setting key type switch 74 is turned on by being turned clockwise by 90 degrees (step 175). 177). Setting key type switch 7
If No. 4 is not turned on, it is next determined whether the backup is normal or not (step 179). If the backup is normal, the process returns to the state when the power was turned off. (Step 180).

If the setting key type switch 74 is turned on in step 177, the lottery probability setting process is performed as follows (step 178).

FIG. 16 is a flowchart showing the details of the lottery probability setting process in step 178.

First, the lottery probability set value when the power is turned off is read by the CPU 31 (step 19).
1). The lottery probability set value is set by a two-digit numerical value. The lower one digit is set to the setting values 1 to 6 shown in the probability lottery data table, and the upper one digit is a lottery for setting the lottery probability. The role is set by a numerical value of 1 to 3. The lottery combination number 1 is a lottery combination “BB” and the number 2 is a lottery combination “R
B ”and the numerical value 3 correspond to the lottery combination“ 2 cherry ”.

Next, it is determined whether or not the lottery combination value is 3 or less (step 192). If the lottery combination value exceeds 3, the lottery combination value is set to 1 (step 19).
3). If the lottery combination value is 3 or less, and step 19
When the numerical value is set to 1 in step 3, the display drive circuit 42 is driven under the control of the CPU 31, and the lottery number value is displayed in the first digit of the payout number display section 25 (step 194).

Next, it is determined whether or not the start lever 15 has been turned on with reference to the start switch 15S (step 195). If the start lever 15 has not been turned on, the reset switch 73 is next turned on. It is determined whether or not has been turned on (step 196).
When the reset switch 73 is turned on, 1 is added to the lottery combination value (step 197), and step 192 is performed.
Return to the processing of.

On the other hand, if the ON operation of the reset switch 73 is not detected in step 196 and the ON operation of the start lever 15 is detected in step 195,
The number of lottery combinations is set to one of 1 to 3, and the lottery combinations for setting the lottery probability are "BB", "RB", "2 cherry".
After determining any one of the above, the process proceeds to the next process.

Next, it is determined whether the lottery probability set value read in step 191 is 6 or less (step 19).
8) If the lottery probability setting value exceeds 6, the setting value is 1
Is set to (step 199). If the lottery probability set value is 6 or less, and if the set value is set to 1 in step 199, then the display drive circuit 42 is driven under the control of the CPU 31, and the lottery probability set value is displayed on the payout number display unit 25. It is displayed in the last digit (step 200).

Next, it is determined whether or not the start lever 15 has been turned on by referring to the start switch 15S (step 201). If the start lever 15 has not been turned on, then the reset switch 73 is turned on. It is determined whether or not has been turned on (step 202).
When the reset switch 73 is turned on, 1 is added to the lottery probability setting value (step 203), and step 1 is executed.
It returns to the process of 98.

On the other hand, when the on-operation of the reset switch 73 is not detected in step 202 and the on-operation of the start lever 15 is detected in step 201,
The lottery probability setting value is set to one of 1 to 6.

Next, it is determined whether or not the setting key type switch 74 has been turned 90 degrees counterclockwise and turned off (step 204). If the setting key type switch 74 has been turned off, the lottery probability setting process ends. .

Here, the reset switch 73, the setting key type switch 74, the display drive circuit 42, the payout number display section 2
5 and the microcomputer 30 individually determine the value of the lottery probability for the winning mode of “BB”, “RB”, and “2 cherries” for each of the winning modes, as one desired value among the six values. Constitutes a lottery probability setting means.

In this embodiment, the winning combinations whose probability lottery data changes according to the lottery probability setting are “BB” and “R”.
Although the description has been given of the three cases of "B" and "two cherries", the lottery probability data of the winning combination such as "bell" and "plum" may be changed by the lottery probability setting.

In this embodiment, a unit in which the lottery probability data is changed by one setting, that is, one setting unit is any one of “BB”, “RB”, and “two cherry” The case where there is one individual winning combination is described. However, one setting unit may be assigned to a plurality of winning combinations, and the lottery probability data of the plurality of winning combinations may be changed at a time by one setting operation. For example, "BB"
And a bonus prize such as “RB” are treated as one setting unit, and the setting values of these winning combinations are collectively set to, for example, 3 by one setting operation, and the lottery probability data is changed collectively. .

After the lottery probability setting process of step 178 in FIG. 13 is performed as described above, next, initialization at the start of the game is performed in a predetermined storage area of the RAM 33 (FIG. 1).
3, step 181).

Next, the CPU 3 determines whether or not there is a replay (replay) as a result of the previous game and there is automatic medal insertion.
1 (see FIG. 14, step 101). If there is this automatic insertion, the game medals corresponding to the insertion request are then automatically inserted (step 102). On the other hand, if there is no automatic insertion, the player next inserts medals into the medal insertion slot 9 and waits for a detection signal to be input from the medal sensor 9S (step 103).
Or, BET switches 10, 11, 1 depending on the player.
2 is operated and waits for signals from these switches to be input. Up to three medals can be inserted during a general game, and one medal can be inserted in a bonus game during a BB game or an RB game.

Next, by operating the start lever 15,
It is determined whether or not a start signal has been input from the start switch 15S (step 104). If this determination is "YES", it is next determined whether 4.1 seconds have elapsed since the previous game (step 105). 4.
If one second has not elapsed, the waiting time for starting the game is consumed until 4.1 seconds have elapsed (step 106).
After 4.1 seconds, a winning determination is made by the winning mode determining means. That is, a random number for lottery generated by the random number generator 36 is extracted by the sampling circuit 37 (step 107), and a probability lottery process is performed (step 108).

This probability lottery process is performed in accordance with FIG. 17 and FIG.
Is performed according to the flowchart shown in FIG. 3, and the determination is made by determining which one of the winning groups belongs to the winning probability table in the winning probability table. That is, first,
The accumulated area of the probability lottery value secured in the RAM 33 is cleared (FIG. 17, step 131). Next, RAM3
The winning number 1 is set in the winning number storage area in No. 3 (step 132). This winning number is shown in the lottery data table for each gaming state in FIG. 19, and the winning number 1 corresponds to the winning of two cherries.

In the same table, the number of lotteries, the lottery combinations, and the order are shown for each game state of general game, BB, RB inside, and BB general game. In the game state of the general game, the number of lotteries is expressed as seven, and two cherry, four cherry, plum, bell, re-game, RB,
And lottery combinations of BB and BB and their order 1 to 7 are shown. The above winning numbers correspond to this order, and order 1 is the winning number 1. In addition, BB, RB inside hit,
In each game state of the general game during BB, the number of lotteries is represented as 5, and the lottery combinations and the order excluding RB and BB are represented.

Next, the probability lottery data table during the BB regular game is set in the probability lottery data table storage area of the RAM 33, and the number of lotteries during the BB regular game (5 times)
Is set in the lottery count storage area of the RAM 33 (step 133). Next, a game state flag described later is referred to to determine whether the current game state is the BB operation, that is, whether the current game state is just the BB game state (step 134).

If the BB operation is being performed, the process proceeds to step 138 described later. If the BB operation is not being performed, it is next determined whether or not the BB or RB is hitting inside (step 135). When the inside of the BB or RB is being hit, the probability lottery data table for the inside of the BB or RB is set in the probability lottery data table storage area of the RAM 33, and the number of lotteries (5 times) for the inside of the BB or RB is set. It is set in the lottery count storage area (step 136).

If the inside of the BB or RB is not hit, the probability lottery data table in the general game is stored in the RAM 3
3 is set in the probability lottery data table storage area, and the number of lotteries during normal game (seven times) is set in the lottery number storage area (step 137).

Next, the number of medals inserted into the machine is checked (step 138), and the probability lottery data for one medal is set in the probability lottery data storage area of the RAM 33 (step 139). Next, it is determined whether or not the number of inserted medals is one (step 140).
If the number is one, the process proceeds to step 144 described later. If the number is not one, the probability lottery data for two medals is set in the probability lottery data storage area of the RAM 33 (step 141). Next, it is determined whether or not the number of inserted medals is two (step 142). In the case of two sheets, the process proceeds to the process of step 144 described later,
If not, the probability lottery data for 3 medals is RA
It is set in the probability lottery data storage area of M33 (step 143).

Here, no matter which lottery probability data table is selected, the probability lottery data for each of the lottery combinations of “BB”, “RB”, and “2 cherries” are stored in the lottery probability setting in step 178 described above. In the processing, a desired step value among the six steps has already been individually set.

Next, each size of the set probability lottery data is added to the probability lottery value accumulation area secured in the RAM 33 (FIG. 18, step 144). This addition is first performed with the size of the probability lottery data as aw, and the process returns from step 148 to be described later and returns to step 1
Each time 44 is performed, the size of the probability lottery data bw, c
w, dw, ew, fw, and gw are sequentially added to the probability lottery value accumulation area.

Here, the sizes aw, b of the probability lottery data
w, cw, dw, ew, fw, and gw are the sizes of the respective sections of the prize mode in the prize probability table shown in FIG.
As already described for each size when the number of inserted medals is three, aw = a, bw = ba, cw = c-
b, dw = dc, ew = ed, fw = fe, gw =
gf. By the first addition performed with the size of the probability lottery data as aw, the probability lottery value accumulated value D becomes aw.

Next, the random number specified by the sampling circuit 37 is set to X in the expression XD (step 145). By calculating this formula, it is determined whether or not a winning mode defined by the probability lottery data has been won (step 146). That is, X-D
It is determined whether the calculation result is positive or negative. If the calculation result is negative, that is, if the value of the random number value X is smaller than the value of the cumulative value D, the specified random number is used as the probability lottery data. It belongs to the prize mode divided by. The accumulated value D at the beginning of the process is aw, and in this case, when the calculation result is negative, the lottery result is a winning mode divided by a, that is, a small winning of two cherries, and the process will be described later. Proceed to 150.

On the other hand, if the calculation result is positive, 1 is added to the winning number stored in the winning number storage area (step 147). Initially, 1 is set in this winning number storage area in step 132, so that the winning number becomes 2 by this initial addition processing in step 147. It is understood from the table in FIG. 19 that the winning number 2 corresponds to four cherries. Thereafter, every time this process is performed, the winning numbers are counted up to 3, 4, 5,.... Next, it is determined whether or not the number of lotteries has reached the specified number stored in the lottery number storage area (step 148).

If the lottery for the specified number of times has not been completed, the process returns to step 144, and bw which is the size of the next probability lottery data is added to the probability lottery value accumulation area. Then, according to the processing of steps 145 and 146, X
The calculation of −D is performed, and the sign of the calculation result is determined. When the size bw of the probability lottery data is added to the probability lottery value accumulated value D by this processing, the value of D becomes aw + bw
become. In this case, if the calculation result is negative, it is assumed that the random number specified by the sampling belongs to the prize mode divided by the probability lottery data b, the lottery result is a small winning of four cherries, and the processing is performed. The process proceeds to step 150 described later.

On the other hand, if the calculation result is positive, it is determined that the winning mode defined by the probability lottery data has not been won, and the winning number is counted up according to step 147, and the winning number is set to 3. Thereafter, it is determined in step 148 whether or not the number of lotteries has reached the specified number. If not, the process returns to step 144 and the same processing as described above is repeatedly performed.

If the number of lotteries reaches the specified number in step 148, the value X of the specified random number is determined to be greater than or equal to the maximum value of the probability lottery value accumulated value D, and the random number does not belong to any of the winning modes. As a result, the lottery result is lost. Therefore, the lost number 0 is set as the winning number (step 149).

In the specific processing of steps 144 to 148, the range of random numbers to be extracted is 0 to 16384, and the probability lottery in the general game state in the probability lottery data table for three betting shown in FIG. When the data is shown in FIG. 20, it is performed as follows. Here, step 17
In the lottery probability setting process 8, the lottery combination “BB” is set to 4 and the probability lottery data gw3 is set to 61. The lottery combination “RB” is set to 1 and the probability lottery data fw3 is set. Is set to 50 and the lottery role "2 cherry"
Is set to 6 and the probability lottery data aw3 is 260
5 is set.

For example, assuming that a random number 6954 is extracted in the normal game state, X = 6954, and the initial D = 260.
5 (probability lottery data aw3 for two cherries)
The calculation of X-D is as follows.

6954−2605 = 4349 (1) Since 4349 of this calculation result is a positive number, the winning number is set, and 1 is added to the winning number set to 1 and the winning number is set to 2. . Since the specified number of lotteries in the general game state is seven, the specified number of lotteries is not completed, and the same processing is repeated again. That is, the probability lottery data bw3 of the next four cherries is added to the accumulated value D, and D = 2605 + 2200 = 4805, and the next X−
D is calculated.

6954-4805 = 2149 (2) Since 2149 of this calculation result is also a positive number, it is not elected and 1 is added to the election number set to 2 and the election number is set to 3. . Also here, since the specified number of lotteries has not been completed, the same processing is repeated again. That is, the probability value lottery data c of the next plum is added to the cumulative value D.
w3 is added to make D = 4805 + 2100 = 6905, and the next X-D calculation is performed.

6954-6905 = 49 (3) Since 49 of this calculation result is still a positive number, it is not elected. One is added to the election number set to 3 and the election number is set to 4. You. Also here, since the specified number of lotteries has not been completed, the same processing is repeated again. In other words, the next-bell probability lottery data dw3
Are added to make D = 6905 + 300 = 7205, and the next X-D calculation is performed.

6954-7205 = -251 (4) Since this calculation result is a negative number, the winning is made, the winning number becomes 4, and the winning pattern divided by the probability lottery data dw3, that is, the small win winning pattern of the bell You have been elected.

Thereafter, a winning request flag corresponding to the winning number is set (step 150). The types of the hit request flag include “two cherries”, “four cherries”,
There are seven types of “plum”, “bell”, “re-game”, “RB”, and “BB”, and one of these is set in a predetermined area of the RAM 33.
If none of the hit request flags are set, "losing" occurs.

The probability lottery process in step 108 of FIG. 14 is performed as described above. Next, reels 3 to 5
A predetermined area of the RAM 33 in which each rotational position of
Initialization is performed at the start of reel rotation (step 109 in FIG. 14). Subsequently, each of the reels 3 to 5 is driven to rotate by the stepping motor 55. Next, it is determined whether any of the stop buttons 16 to 18 has been turned on (step 110). If the ON operation has not been performed, it is determined whether or not the automatic stop timer has reached 0 (step 111). The automatic stop timer is for automatically stopping each of the reels 3 to 5 after a predetermined time elapses when the stop buttons 16 to 18 are not operated for a predetermined time.

When any one of the stop buttons 16 to 18 is turned on or the automatic stop timer becomes 0, the number of frames of the symbol drawn on the activation line by the stop display control means, that is, the sliding frame A number is determined (step 112). This number of sliding pieces is
It is determined from the winning request, the number of control frames, the symbol position, and the like.

The game state is the RAM 3 shown in FIG.
The game state is stored in a one-byte area called a game state (game state flag) 3 and hexadecimal data 01 to 05 indicates the game state at that time. The gaming state stored in this gaming state status includes:
"RB working", "BB working", "General game",
There are five types of “BB inside hit” and “RB inside hit”.

"RB operation in progress" indicates a game state during the RB game. RB means a regular bonus game. In this RB game, a bonus game in which a plurality of high payout games are combined can be performed once. "BB
"In operation" indicates a gaming state during the BB game. BB
Means a big bonus game and this BB
In the game, a set of the general game and the bonus game can be performed a plurality of times.

"Normal game" indicates a game state in which neither BB nor RB wins. In the small hit prize generated in the general gaming state, a plum generated with three plum symbols aligned on the activation line, a bell generated with three bell symbols aligned, and a cherry symbol generated on the first reel 3 There are two cherries generated by stopping on one activation line, and four cherries generated by arranging cherries on two activation lines. Here, the number of medals paid out is 15 when a plum is won, and 8 when a bell is won.
When a two-piece cherry prize is awarded, four pieces are provided, and when a two-piece cherry is awarded, two pieces are provided.

"BB inside hit" is a general game state in which the BB hit request flag is set, but a predetermined winning symbol combination is not stopped and displayed on each of the reels 3 to 5, and the BB game has not yet entered. Is represented. “RB inside hit” indicates that the RB hit request flag is set, but a predetermined winning symbol combination is not stopped and displayed on each of the reels 3 to 5 and the general gaming state in which the RB game has not yet been entered. I have.

The winning request also consists of one byte.
It is stored in the hit request flag storage area of the RAM 33 shown in FIG. For example, 1 is assigned to bit 7 of this storage area.
Indicates that the hit request flag is “BB”, while 1 indicates that the hit request flag is “RB”. Two types of hit request flags may be set at the same time.

For example, BB request flag or RB
When the winning request flag is set, the winning request flag is set to the next game unless the symbol combination corresponding to “BB” or “RB” is stopped and displayed on each of the reels 3 to 5 in the current game. Carried over. Therefore, "BB
At the time of the next game of “inside win” or “RB inside win”, if the win mode is determined by the win mode determination means, the win request flag of the small win mode is set. Therefore, the hit request flag of “BB” or “RB” and the hit request flag of the small hit prize are simultaneously set.

As shown in FIG. 22, the number of control frames depends on the order of symbols for which the pull-in control is prioritized.
3 is stored as a table. The drawing shows a pull-in priority table during a general game. During a general game, the pull-in priority is determined in the order of replay, small hit, and BB / RB game. This priority is the priority of the winning combination that is preferentially drawn on the activation line. When two types of winning modes are simultaneously requested as described above, or when a winning mode is determined by the winning mode determining means, a winning mode having a higher priority is determined according to the predetermined priority. The pattern according to is preferentially drawn. The control frame number is a frame number within a range in which the CPU 31 can control the pull-in, and during a general game, each winning combination is set to 4 frames.

The symbol position is the position data of each of the reels 3 to 5 written in the area of the RAM 33 initialized in step 109. This symbol position is the data of the symbol present at each activation line at that time, and is stored as the symbol code shown in FIG.

When determining the number of sliding frames, first, the current game state is referred to, and a priority order table according to the game state is selected. In other words, if it is a general game state, FIG.
The table shown in FIG. 2 is selected. Next, the number of control frames of the winning combination according to the winning request is referred to from the selected table. Thereafter, the symbol position at that time is referred to, and the symbol at that time on the activation line of the first stop reel is grasped. If this symbol is not a symbol corresponding to the winning request, it is determined whether there is a symbol corresponding to the winning request within the range of the number of control frames referred to. If the symbol corresponding to the winning request is within the range of the number of control frames, the number of frames from the activated line to the symbol is determined as the number of sliding frames.

Next, the number of sliding frames is stored in a predetermined area of the RAM 33 so that the first stop reel (rotating drum) rotates by the number of sliding frames determined in this way (FIG. 14, FIG. 14).
Step 113). Thereafter, the stop request flag of the first stop reel is set (step 114). CPU31
Stops the rotation of one reel in response to the stop request flag being set.

Next, it is determined whether or not all the reels have stopped (step 115 in FIG. 15). If the second reel and the third reel have not been stopped, the process returns to step 110, and the above processes are repeated.

Steps 110 to 1 by the CPU 31
The reel stop processing of No. 15 is performed as follows during a general game, for example.

For example, when the ON operation of the first reel stop button 16 is detected, the first reel stop button 16
Is operated by the player, the number of drive pulses supplied to the stepping motor 55 of the first reel 3 becomes R
The information is read from the AM 33 and is associated with the rotation position of the first reel 3. When the rotational position of the first reel 3 is known, three symbols appearing in the observation window 6 are grasped as symbol codes by contrast with the symbol table (see FIG. 12).

In this case, when the big hit hit request flag is set, it is checked whether or not there is a symbol constituting a big hit on the activated pay line in the observation window 6. Similarly, when the hit request flag for medium hits and small hits is set, it is checked whether there is a symbol constituting a medium hit or small hit on the activated pay line in the observation window 6. When there is a symbol corresponding to the hit request flag on the activated pay line, the CPU 31 immediately stops the first reel 3.

As a result of the above check processing, if the symbol corresponding to the hit request flag does not appear on the activated pay line in the observation window 6, the first reel 3 is further rotated by the number of control frames (four symbols). Check what kind of symbols appear when you let them. If there is a symbol corresponding to the hit request flag, the number of sliding frames up to that frame position is reached, and the first reel 3 is rotated by the number of sliding frames and stopped there. This pull-in control process is performed in the same manner at the time of each stop control process of the second reel 4 and the third reel 5 described below.

Next, when the stop button 17 of the second reel 4 is turned on, a stop control process of the second reel 4 is performed. In this stop control process, first, in the state where the second reel 4 is rotating, first, the pay line L at the center of the observation window 7 is set.
Assuming that 21 symbols of each code number 0 to 20 stop at 1, a combination with the symbols of the first reel 3 already stopped on the activated pay line is read. In addition, a rotation code indicating that the third reel 5 is rotating is read. Although the second reel 4 is also rotating, it is assumed that the second reel 4 is stopped by the above-described processing, so that it is not read as a rotation code.

When the combination of symbol codes is read in this way, the winning symbol combination table described above is referred to, and the second reel 4 rotates the 21 rotation positions with respect to the symbol determined by stopping the first reel 3. , It is sequentially determined what kind of winning may occur on the activated winning line. For example, FIG.
Assuming that the first reel 3 is stopped as shown in FIG. 3A, the symbol combination pattern at that time is checked assuming 21 stop positions of the second reel 4. For example, as shown in FIG.
At the center of the code number "5", the symbol combinations on the pay lines L1, L2A, L2B, L3A, L3B are as shown in FIG.

The arrow on the third reel 5 is a rotation code indicating that the reel is being rotated. Depending on the stop position of the third reel, "AAA" may be a big hit or a winning line depending on the stop position of the third reel. There is a possibility that a small hit prize of “EEE” may occur in L2B. Therefore, for the code number "5" of the second reel 4, a big hit prediction flag and a small hit prediction flag are set as shown in FIG. The presence or absence of such a prediction flag is checked for all code numbers on the second reel 4, and these data are written to the RAM 33.

The prediction flag data written in the RAM 33 in this manner is referred to when the second reel 4 is stopped. That is, when the stop button 17 of the second reel 4 is operated, the prediction flag corresponding to the code number of the second reel 4 is referred to. The stop control of the second reel 4 is executed such that the symbol of the big hit stops.

Next, when the ON operation of the stop button 18 of the third reel 5 is detected, the stop control processing of the third reel 5 is performed. In this stop control processing, the first reel 3 and the second reel 4 have already stopped and the combination of the symbols has been specified. Therefore, the combination of these symbols is provided for each code number of the third reel 5. The possibility of winning is determined, and a winning expectation flag is set in the same manner as in the table shown in FIG.

The prediction flag data is also referred to when the stop button 18 of the third reel 5 is operated, and when a big hit is predicted, the big hit symbol is stopped on the activated pay line. Stop control of the third reel 5 is executed. At the time of the stop control processing of the third reel 5, not only a winning according to the winning request flag but also a winning different from the winning request flag can be obtained by the combination with the symbols of the first reel 3 and the second reel 4 which have already stopped. The reel stop position is controlled so as to not obtain the following.

When the reel stop control processing is completed, next, a winning search processing is performed (step 116 in FIG. 15). In the winning search process, the type of the winning flag indicating the combination of the symbols actually arranged on the activated winning line matches the type of the hit request flag determined by the probability lottery process. Then, it is determined whether or not the winning flag is normal (step 11).
7). If this determination result is not normal, for example, if the symbol combination of bells is aligned on the activated pay line and the hit request flag is a plum flag, the medal payout number display section 25 of the front panel 2 Displays an illegal error (step 118).

If the winning flag is normal, it is next determined whether or not the winning number is 0 (step 119). If the winning number is not 0, then the game medals are stored or paid out according to the state at that time (step 1).
20). That is, in the state where the game is played with credits, the number of credits is increased by the number of medals obtained by winning, and in the state where the game is played by inserting medals into the slot 9, the number of medals obtained by winning is obtained. The number of medals is paid out to the tray 20.

Next, it is determined whether or not the winning mode is a replay winning (step 121). If the winning mode is a replay winning, an automatic insertion request is set (step 122). Then, initialization at the end of one game, for example, the area of the RAM 33 used in the game is initialized (step 123).
One game is over.

In this embodiment, conventionally, “B
The setting of the lottery probability for each of the lottery combinations "B", "RB", and "2 cherries" was performed uniformly, but as described above, "BB", "RB", "2 cherries" Is set individually for each winning mode.
That is, conventionally, when the setting of the lottery probability is set to 1,
Although the probability lottery data of each lottery combination is uniformly set to the setting 1, in the present embodiment, the setting 4 is set for the lottery combination "BB", the setting 1 is set for the lottery combination "RB", and the lottery combination "2 "Cherry" can be set individually for each lottery combination such as setting 6. Further, it is also possible to uniformly set the probability lottery data of each lottery combination as in the related art.

Therefore, according to the present embodiment, it is possible to provide a variation in the adjustment of the machine split, which is the ratio of the number of payout medals to the number of inserted medals. Therefore, for example, it is difficult to win a small hit prize such as a two-piece cherry but easy to win a BB game, or a game property such as winning a small hit prize immediately but not easily winning a BB game, or paying out medals. Can change more than ever before.

In the above embodiment, the case where the present invention is applied to a slot machine has been described, but the present invention is not limited to this. That is, the present invention is also applied to a ball-and-ball game machine such as a pachinko machine, which includes a lottery probability setting means for setting a value of a lottery probability for a plurality of predetermined winning modes to a desired value from a plurality of values. In this case, the same effect as in the above embodiment can be obtained.

[0123]

As described above, according to the present invention, the setting of the probability lottery value which has been uniformly performed for all of a plurality of predetermined winning modes is individually set for each of the winning modes. become. Also, it is set for each of at least two or more winning modes. For this reason, it is possible to give a wide range of adjustments to the machine split, and it is possible to change the game characteristics and payout more than ever, and the interest of the game is improved.

For example, the lottery probability of the small hit prize during the general game is set high so that the number of medals in hand is not immediately reduced, but the lottery probability of the big hit prize is set low, The payout characteristics such as setting the lottery probability of the small hit prize in the middle and immediately reducing the number of medals in hand, instead of setting the lottery probability of the big hit prize, making it easier to generate the big hit prize continuously Can be easily adjusted. That is, according to the present invention, it is possible to finely adjust the payout characteristics of the gaming machine while keeping the overall medal payout ratio the same.
