Description

  The present invention relates to gaming machines such as pachislot machines that use medals, coins, game balls, and the like as game media, slot machines such as parrot machines.

  Conventionally, in game machines, particularly pachislot machines, a predetermined number of game media are inserted and a start lever is operated to execute a winning lottery for the game, and a plurality of symbols are displayed on the peripheral surface. In addition, when a plurality of rows (generally, three rows) of symbol variation reels (display devices) rotate, so-called symbol variation display is started.

  The symbol-variable reels that have started rotating by the operation of the start lever described above can be brought to a position that is almost intended by the player within the range of the number of symbols to be adjusted by the player operating the stop buttons provided correspondingly. Stopped.

  Here, when the start lever is operated, an internal lottery is executed and the winning / losing of the winning combination is determined, and the player performs the stop operation of each symbol variable reel by the stop button, and wins the internal lottery. In some cases, the winnings will be won and the rights will be exercised when the symbols corresponding to the winning are complete.

  Further, according to the result of the internal lottery, the symbol variation reel performs pull-in control of the winning symbol and kick-off control of the non-winning symbol within the range of the number of symbols to be adjusted from the symbol position at the time when the player stops the operation, As a result of internal lottery, if the winning combination is won, it will be easier to display the winning symbol combination by drawing in the winning symbol within the number of adjustment symbols, and if the internal lottery result is out The symbol variation reel is stopped by performing so-called slip control so as not to display the symbol combination corresponding to the winning combination.

  Even if the result of the internal lottery is a win, if the symbol variable reel is not stopped and displayed with the symbol corresponding to the winning combination, no winning is made and the above right is not exercised.

Conventionally, a gaming machine is configured so that a plurality of winning combinations can be won simultaneously by an internal lottery, and both winning combinations can be displayed, and a lottery or a predetermined condition (for example, a combination advantageous to a player is given priority). ) Etc., it has been proposed to display any combination (for example, see Patent Document 1).
JP2004-222873

  However, in the conventional gaming machine as described above, since the overlapping degree of the combination in the winning area where a plurality of combinations are won at the same time is always constant, the expectation of the combination does not change and the gameability is poor. There was a point.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a gaming machine that can improve the gameability by changing the degree of expectation for a combination without reducing the winning probability of any combination. It is.

  In order to solve the above-mentioned problem, the invention according to claim 1 includes a display means capable of displaying a plurality of symbols in a variable manner, and according to a start instruction, a small role in which a lottery result is reflected only in a winning game, and Once winning, the lottery results will continue to be reflected until a predetermined condition is met. A lottery that allows a single winning or multiple winnings to be performed is performed on any of the multiple roles including the leading role, and a variable display on the display means is started. And a gaming machine for winning the winning combination when the display means after the variable display stop based on the subsequent stop instruction is in a predetermined display state, comprising a plurality of patterns of the winning combination In addition, the normal game control means for executing the normal game for executing the lottery with a predetermined winning probability, and the winning probability for each winning combination and the pattern of the winning winning combination according to the game progress status are changed. And without, a, a changing means for changing the balance of the winning probability of patterns of the role of the overlapping winning.

  According to the first aspect of the present invention, the display means capable of variably displaying a plurality of symbols is provided, and a small role in which a lottery result is reflected only in a game won in accordance with a start instruction and a predetermined condition once won. A lottery that allows a single winning or multiple winnings to be performed on any of a plurality of roles including a leading role that continues to reflect the lottery result until it is satisfied is executed, and a variable display on the display means is started, based on a subsequent stop instruction A game machine such as a pachislot machine that wins the winning combination when the display state after the variable display stop of the display means is in a predetermined state, and is provided with a plurality of patterns of double winning combination as a normal game The lottery is executed with a predetermined winning probability.

  Here, in the present invention, the balance of winning probabilities between the winning winning patterns is changed without changing the winning probabilities for each winning combination and the winning winning pattern depending on the game progress status. I am doing so.

  That is, for example, when there are three patterns of (1) A and B, (2) A and C, and (3) A and D as the patterns of the winning combination, the winning probability of (1) at a certain point in time Is 5%, the winning probability of (2) is 10%, and the winning probability of (3) is 2%, the probability of overlapping winning is 17%. When these balances are changed according to the game progress, the probability of overlapping winning remains 17%, for example, the winning probability of (1) is 1%, the winning probability of (2) is 1%, ( The winning probability of 3) can be changed to 15%.

  At this time, since the winning probabilities of the respective roles of A, B, C, and D are not changed, there is no change in the probability of winning independently for A, and the winning probability of 4% is independent for B. As for C, the probability of winning alone is increased by 9%, and for D, the probability of winning alone is reduced by 13%.

  Thereby, it is possible to improve the gameability by changing the degree of expectation for the winning combination without reducing the winning probability of any winning combination.

  Further, according to the present invention, as in the invention described in claim 2, when the winning combination includes a replay in which a game equivalent to the winning game is executed as a next game when winning, and when a predetermined condition is satisfied, Replay time execution means for executing a replay time for dramatically increasing the winning probability for replays compared to the normal game is further provided, and the changing means is configured to increase the winning probability for the replays by the replay time executing means. In addition, it is possible to change the balance of the winning probabilities among the winning winning patterns without changing the winning probabilities for the winnings excluding the replay and the overlapping winning winning patterns.

  Thereby, not only the winning probability for replay is different between the replay time and the normal game, but also the expectation for the combination is changed, so that the gameability can be improved.

  Further, as in the invention described in claim 3, further comprising a big game control means for executing a big game when the big game is won, wherein the predetermined condition is the end of the big game by the big game control means. You can also In other words, the present invention can also be applied to a model that executes a replay time after execution of a big game.

  Further, as in a fourth aspect of the invention, the plurality of winning combinations include a replay time operation pattern for executing a replay time that dramatically increases the winning probability for the replay in comparison with the normal game when winning. The predetermined condition may be a winning for the replay time operation symbol. That is, when the replay time is won by lottery and the display means wins a replay time operation symbol in a predetermined display state, the present invention can be applied to a model that executes the replay time.

  Further, according to the present invention, as in the invention of claim 5, the pattern of the winning combination that overlaps the winning combination may be a combination of the leading role and the small role. A special sense of expectation can be given, and the expectation of the small role changes according to the gaming state, so that the gameability can be further improved.

  As described above, according to the present invention, according to the progress of the game, without changing the winning probability for each winning combination and the pattern of the winning winning combination, the winning probability between the winning winning patterns of the winning combination pattern. Since the balance is changed, it is possible to provide a gaming machine that can improve the gameability by changing the degree of expectation of the winning combination without reducing the winning probability of any winning combination.

  Further, the operation timing by the start lever 354 is an internal lottery timing which will be described later, and the winning (winning) / off is determined by the operation of the start lever 354.

  FIG. 2 schematically shows a control block diagram for controlling the operation of the pachislot machine 300.

  The control system of the pachislot machine 300 is configured with the main control unit 100 as the center, and the main control unit 100 identifies medals inserted from the medal insertion unit 320, and the number and types of medals inserted (incorrect or And a stop button 356A, 356B, 356C, a MAX bet button 352B, and a single bet button 352A corresponding to the start lever 354 and the above-described reels 350A, 350B, and 350C, respectively. In addition, a settlement button 103 for returning a medal stored (credited) inside the gaming machine when the game is stopped is connected via a sensor (not shown) that detects an operation state.

  The main control unit 100 also includes a main control circuit 110 that includes a CPU, and the main control circuit 110 temporarily stores various control parameters mainly according to the progress of the game. A RAM 128 and a ROM 130 in which various programs are stored are connected, and a clock pulse generation circuit 124 that generates a clock pulse serving as a reference for the operation of the main control circuit 110 is connected via a frequency divider 126. Yes.

  Further, a random number generator 120 and a random number latch circuit 122 are connected to the main control circuit 110. The main control circuit 110 controls the random number generator 120 in synchronization with the clock pulse input through the frequency divider 126 to sequentially generate random numbers, and the random number latch circuit 122 generates the random number. Get random numbers.

  In the pachislot machine 300, an internal lottery that determines a winning combination at the operation timing of the start lever 354 is performed by the main control unit 100. In the main control circuit 110, when the start lever 354 is operated, the random number The latch circuit 122 is instructed to acquire, hold, and output a random number, and thereby a lottery result is derived according to the random number input from the random number latch circuit 122.

  If the internal lottery is a win (role winning), a winning operation will be awarded when the winning symbols are aligned by the stop operation by the subsequent stop buttons 356A, 356B, 356C, and the player can acquire the number of medals according to each symbol. The gaming state is advantageous to the player in accordance with the arranged symbols.

  Here, the combination includes a small combination and a large combination, each having a different degree of advantage for the player. When winning a small role, a predetermined number of medals are paid out according to the role, while when winning a big role, a bonus game corresponding to the role is executed. This bonus game is configured to be able to execute a plurality of small role games. For this reason, naturally, the bonus is more advantageous to the player than the small role.

  In addition, a motor drive circuit 132 is connected to the main control unit 100, and the motor drive circuit 132 includes left (L), middle (C), and right (R) reel motors 106A, 106B, Each of the left, middle, and right reels 350A, 350B, and 350C is connected via 106C.

  Further, in the pachislot machine 300, the symbol variation by the symbol variation unit 316 is started at the operation timing by the start lever 354. When the start lever 354 is operated, the main control unit 100 operates the motor drive circuit 132. The reel motors 106A, 106B, and 106C are respectively started to rotate, and the three reels 350A, 350B, and 350C are rotated, and the three stop buttons 356A, 356B, and 356C are operated on the basis of the subsequent operations. The rotation of the reels 350A, 350B, and 350C is stopped.

  Here, in the main control unit 100, when the rotation of the reels 350A, 350B, and 350C is stopped based on the stop operation by the stop buttons 356A, 356B, and 356C, the predetermined number of symbols is controlled according to the result of the internal lottery. Is supposed to run.

  In other words, when the stop button 356A, 356B, 356C is operated at the stop timing at which the symbol that stops only on the winning line is stopped on the active line when the internal lottery is off, intentionally avoiding the stop at this symbol Therefore, control is performed so that the stop position is shifted (kicked off) and stopped at the off symbol arrangement.

  Also, when the internal lottery is won, even if the winning symbol does not stop at the stop timing operated by the player, if the winning symbol is within the predetermined number of symbols, the winning symbol is intentionally stopped on the active line. Performs control to shift (pull in) the stop position.

  By kicking and pulling in the above, it is possible to make the internal lottery result and the game result uniform, and even if the stop operation timing is slightly shifted, it is possible to align the winning symbols, It prevents people from being lost.

  The main control unit 100 is connected to a hopper drive circuit 136 for operating a hopper 138 provided inside the pachislot machine 300. The hopper 138 stores medals, and the main control unit 100 pays out medals from the hopper 138 via the hopper drive circuit 136 in accordance with the stop pattern specified by the output from the reel position detection circuit 134. Executed.

  Further, a medal detection sensor 140 that detects medals paid out from the hopper 138 is disposed in the vicinity of the hopper 138 and is connected to the main control unit 100 via a payout completion signal circuit 142. The payout completion signal circuit 142 determines whether or not the payout is completed based on the detection signal from the medal detection sensor 140, and generates a payout completion signal when it is determined that the payout is completed. Is input.

  When the payout completion signal is input from the payout completion signal circuit 142, the main control unit 100 ends the medal payout by the hopper 138 via the hopper driving circuit 136.

  Further, a display lamp drive circuit 144 is connected to the main control unit 100, and the 7-segment display unit 315A, the display unit 315B, the 7-segment display unit 315C, and the medal are inserted through the display lamp drive circuit 144.

The notification effect by the above is executed.

  FIG. 3 is a block diagram functionally showing a control system for normal game control in the main control unit 100 according to the present embodiment.

  The main control unit 100 includes a lottery unit 180, and an operation signal indicating that the start lever 354 has been operated is input to the lottery unit 180. The lottery unit 180 executes an internal lottery with the operation of the start lever 354 after a predetermined number of medals have been inserted (bets) as a trigger.

  The lottery unit 180 acquires a random value in synchronization with the operation of the start lever 354, and sends the random value to the winning combination / symbol determination unit 184 via the table selection unit 182.

  The table selection unit 182 stores a lottery table in which information (winning area) indicating roles / designs corresponding to numerical values that can be acquired by the lottery unit 180 is stored for each gaming state of the pachislot machine 300. Note that the gaming state of the pachislot machine 300 includes, for example, a normal game, a bonus internal winning, a bonus game in operation, and the like.

  Further, in this embodiment, when winning a prize, it is possible to win a replay in which a game equivalent to the winning game is executed as the next game by an internal lottery, and when the bonus game ends, the winning probability for the replay is increased. A replay time that is dramatically increased over the normal game is executed.

  FIG. 4 shows an example of a lottery table used in the normal game and the replay time. The lottery table is stored in the ROM 130. Further, in the example shown in FIG. 1. Area no. 2, Area No. to win the bell 6. Area no. 4. Area No. where replay and bonus are won simultaneously. 3. Area No. where bell and bonus are won simultaneously. 5, random numbers are assigned to the six winning areas.

  Also, as shown in the figure, in the present embodiment, the types of winning areas are common to the replay time and the normal game executed after the bonus game ends. However, the random number value and the number of random number values assigned to each winning area are different.

  FIG. 5 schematically shows the number of random values assigned to each winning area. (A) shows the number of random values in the normal game, and (B) shows the number of random values in the replay time. It is shown. Note that the length of the band is proportional to the number of assigned random numbers. That is, the longer the band, the greater the number of assigned random number values.

  In addition, since the types of bands correspond to each winning area, and as described in the explanation of the winning area, the bonus may be won simultaneously with replay or the bell. A part of the band indicating the number of the bars is overlapped with the replay and the bell. That is, the length α of the overlapping portion of the replay band and the bonus band is the winning area number. 3, the length β of the overlapping portion of the bell band and the bonus band is the winning area number. 5 corresponds to the number of random values assigned to 5 respectively.

  As shown in the figure, in the replay time, the area No. to be won for the replay is shown. The biggest feature is that the random number assigned to 2 is increased compared to the normal game. Area No. to win this replay As the number of random number values assigned to No. 2 increases, the area no. The random number assigned to 1 is decreased.

  That is, as shown in the figure, the total number X of random numbers assigned to the areas (No. 3, No. 4, and No. 5) to be won for the bonus and the areas (No. 5 and No.) for which the bell is to be won. The total number Z of random values assigned to .6) is the same between the normal game and the replay time, and the winning probability for the winning except for the replay does not change between the normal game and the replay time.

  By the way, in the present embodiment, in the normal game and the replay time, the area where the replay or the bell and the bonus are simultaneously won in order to improve the gameability without changing the number of the winning areas and the winning probability for the role excluding the replay. No. 3 and no. The number of random values assigned to 5 is made different between the normal game and the replay time.

  That is, as shown in FIG. 3, no. 4 and no. The number of random numbers X (fixed) assigned to the area No. The number α (variation) of random numbers assigned to the area No. The number of random numbers β assigned to 5 (variation), the area no. When the number Y (fixed) of random numbers assigned to 4 is used, all the following formulas (1) to (3) are satisfied in any gaming state.

α + β = XY (1)
α> 0 (2)
β> 0 (3)
Therefore, there are various variations in addition to the assignment method shown in the figure, and as an example, the assignment method shown in FIGS. 6A and 6B is also conceivable. In the example shown in FIG. 6, since the probability of winning a bonus at the same time is increased when the bell is won at the replay time, the expectation to win the bell is higher than the normal game during the replay time. Therefore, the expectation of the role is different between the normal game and the replay time, and the game performance is improved.

  In the table selection unit 182, information indicating the current gaming state is obtained from the gaming state control unit 186, and a lottery table for determining the combination / design is selected from the lottery table provided for each gaming state. Based on the lottery table selected by the table selection unit 182, the winning combination / symbol determination unit 184 determines the winning combination (small role (including replay), major player) and the winning symbol, and the determined winning combination and winning The symbol is input to the gaming state control unit 186.

  The gaming state control unit 186 is connected to a gaming program memory 188 in which data indicating various programs corresponding to the gaming state of the pachislot machine 300 is stored. The game state control unit 186 mainly controls the game state by reading and executing game program data corresponding to the game state from the game program memory 188 as appropriate by the game execution control unit 186A.

  The game program memory 188 stores data indicating a normal game program and data indicating a bonus game program. For example, in the normal game state, the normal game program data is read from the game program memory 188. When the bonus game is in operation, the bonus game program data is read according to the gaming state of the bonus game, and the process is executed based on the program data.

  On the other hand, the main control unit 100 is configured to include a reel drive control unit 194. Based on the start operation of the start lever 354, after a lapse of 4.1 seconds from the start of the previous game, the motor drive unit 132 is provided. Then, the reel motors 106A, 106B, and 106C are driven to start rotation of the reels 350A, 350B, and 350C.

  Further, the reel drive control unit 194 performs stop control for stopping the rotation of the reels 350A, 350B, and 350C based on the operation of the stop buttons 356A, 356B, and 356C.

  Position detection sensors 198A, 198B, and 198C are attached to the reels 350A, 350B, and 350C, respectively, and are connected to the reel drive control unit 194 via the reel position detection circuit 134. The reel drive control unit 194 recognizes the rotational positions of the reels 350A, 350B, and 350C, stops the reels 350A, 350B, and 350C in consideration of the slip control, and also stops the reels 350A, 350B, and 350C that have stopped. The symbol array is sent to the gaming state control unit 186.

  Based on the symbol arrangement of the reels 350A, 350B, and 350C that have been stopped, the gaming state control unit 186 confirms whether or not a winning combination has been won. If a winning combination is awarded, a predetermined payout is made and a winning combination is made. If the small role is replay, the replay game is executed, and if it is a bonus, the game execution control unit 186A reads the bonus game program from the game program memory 188 and executes it.

  As shown in the figure, a flag memory 192 is connected to the gaming state control unit 186 via the flag management control unit 190, and the internal winning state of the combination corresponding to the winning result of the internal lottery described above is flagged. It is managed by the state of.

  Each flag is established by winning in the internal lottery. Generally, the state of the small role flag disappears in one game (flag is not established), but the state of the bonus flag is thereafter determined by each reel 350A, 350B, 350C. By stopping and displaying the bonus symbols in a predetermined arrangement on the display window 314, it is maintained until the bonus is won.

  Note that the flag memory 192 is connected to the reel drive control unit 194 described above, and the state of the flag stored in the flag memory 192 is based on the operation of the stop buttons 356A, 356B, and 356C by the reel drive control unit 194. It is applied as a slip control parameter for pull-in or kick-off during stop control.

  The operation of this embodiment will be described below.

  FIG. 7 shows a flowchart of the game state control process executed by the main control unit 100. Hereinafter, the gaming state control process according to the present embodiment will be described with reference to FIG.

  First, in step 200, the completion of the betting process based on the bet operation via the bet button 352 is waited, and then the operation of the start lever 354 is validated, and the process proceeds to step 202 to wait for the operation of the start lever 354.

  In the next step 204, an internal lottery of the combination is performed, and thereafter, the process proceeds to step 206 to determine whether or not the result of the internal lottery is a bonus winning. If the determination is affirmative, a bonus flag is established, the process proceeds to step 208, the game state is set to the inside of the bonus, and then the process proceeds to step 210.

  Here, the internal lottery is executed based on a table corresponding to the gaming state, and in this embodiment, the winning probabilities as shown in FIGS. 5A and 5B for the normal game and the replay time, respectively. This is executed using the table.

  On the other hand, if a negative determination is made in step 206, the process proceeds to step 210 without setting the gaming state.

  In step 210, rotation of the reels 350A, 350B, and 350C is started, and thereafter, the process proceeds to step 212 to execute reel stop control processing described later, thereby stopping the rotation of the reels 350A, 350B, and 350C.

  That is, when a medal is invested by a bet operation via the bet button, the operation of the start lever 354 is validated, an internal lottery is executed based on the start operation via the start lever 354, and the reel starts rotating.

  The set value is transmitted to the sub control unit 150 at the timing when the start lever 354 is operated. When the internal lottery of the combination is executed, a command indicating the result of the internal lottery is transmitted to the sub-control unit 150.

  Further, based on the operation of the stop buttons 356A, 356B, 356C after the rotation of the reels 350A, 350B, 350C starts, the rotation of the reels 350A, 350B, 350C corresponding to the operated stop buttons 356A, 356B, 356C is stopped. .

  Thereby, the rotation of each reel 350A, 350B, 350C is stopped in a state where the symbols of each reel 350A, 350B, 350C are displayed one by one on each effective line.

  A command indicating the operation timing of each stop button 356A, 356B, 356C and a command indicating the stop position of each reel 350A, 350B, 350C are also transmitted.

  In the next step 214, a combination of symbols stopped on the active line (stop symbol) is specified based on the stop positions of the reels 350A, 350B, and 350C, and the winning symbol of the winning combination won by the internal lottery is determined. If they match and match, it is determined that the winning combination has been won.

  In the next step 216, it is determined whether or not the result of the winning determination is a winning. If the determination is negative, the process returns to step 200 again. If the determination at step 216 is affirmative, the routine proceeds to step 218, where it is determined whether or not the winning combination is a bonus as a result of the winning determination at step 214. If an affirmative determination is made in step 218, the process proceeds to step 224.

  In step 224, after the gaming state is determined to be during the bonus game operation, the process proceeds to step 226 to execute the bonus game, and then the process proceeds to step 236.

  In step 236, the gaming state is set to RT operation, and then the process returns to step 200 again. In other words, when the bonus game ends, the game shifts to the replay time.

  On the other hand, if a negative determination is made in step 218, the process proceeds to step 220, where a predetermined number of medals are paid out as a payout corresponding to the winning combination, and then the process proceeds to step 240.

  In step 240, it is determined whether or not the gaming state is operating in RT. If the determination is affirmative, the process proceeds to step 242 to determine whether or not to end RT. If step 242 is affirmative, the process proceeds to step 244, and after the game state is set to the normal game, the process returns to step 200 again.

  On the other hand, if a negative determination is made in either step 240 or step 242, the process returns to step 200 again.

  As described in detail above, according to the present embodiment, in accordance with the start instruction, the small role in which the lottery result is reflected only in the winning game, and once the lottery is won, the lottery result until a predetermined condition is satisfied. In addition to executing a lottery that allows a single winner or multiple winners to be reflected on any of the major actors that continue to be reflected, start a variable display of a plurality of symbols in the display window 314, and then after the variable display stop based on the stop instruction When a winning combination is won when the display state of the display window 314 becomes a predetermined state, the lottery including a plurality of overlapping winning combination patterns is executed with a predetermined winning probability. The bonus game is executed when the player wins a big game in the game, and the winning probability for the replay is given to the replay in the normal game only for a predetermined period after the bonus game ends. The winning probability of the winning combination between the overlapping winning combination patterns without changing the winning probability for the winning combination excluding replay and the winning winning combination pattern (area No. for overlapping winning) .3 and No. 5 because the replay time is changed to change the balance of the number of random numbers α and the number β) so that they are different from the normal game, so that the winning probability of any combination is not reduced. The game can be improved by changing the degree of expectation.

  Further, according to the present embodiment, since the pattern of the winning combination is a combination of the major role and the small role, it is possible to give a special expectation to the bonus winning combination bonus and the bonus combination. Since the expectation of the small part changes according to the gaming state, the gaming property can be further improved.

  It should be noted that the configuration of the pachislot machine (see FIGS. 1 to 5) and the flow of each process (see FIG. 7) in the present embodiment are merely examples, and can be changed as appropriate.

For example, the replay time may not be executed after the bonus game is ended, but may be executed when a replay action symbol in a predetermined display state is won.
(Other embodiments)
In the above embodiment, the mode in which the winning probability balance between the patterns of the winning combination is different between the normal game and the replay time has been described, but as another mode, in the normal game, in the winning area and each winning area A description will be given of a mode in which the corresponding winning combinations are common, and the balance of the winning probabilities between the patterns of the winning combinations is different according to the progress of the game.

  FIG. 8 schematically shows the number of random values assigned to each winning area in two tables selected in accordance with the progress of the game in a normal game. As shown in the figure, in Table 1 and Table 2, the total number (α + β = X−Y) of random values to be won in duplicate is the same number, and the number α of random values to be won in duplicate for replay and bonus is shown. Only the number β of random numbers to be won in duplicate for the bell and the bonus is different from each other (α> 0, β> 0).

  The selection timing of this table can be set according to the progress of the game. For example, the timing at which the bonus game ends, the timing at which the number of games reaches a predetermined number, or the like can be applied. The table can be selected by selecting a table in a predetermined order (for example, alternately) or by executing a lottery to select which table and selecting the table according to the result of the lottery. it can.

  Thereby, the game nature in a normal game can be improved.
