This application is a continuation in part of U.S. Patent Application titled “Game Machine,” Ser. No. 08/919,016, filed Aug. 27, 1997, pending, and is a continuation in part of U.S. Pat. Application titled “Game Machine,” Ser. No. 09/012,115, filed Nov. 17, 1997, pending, the contents of all of which are hereby incorporated by reference.
The present invention relates to a game machine, and more particularly to a game machine such as a slot machine, poker game machine, or the like, whereby a game is played by inserting coins.
Conventionally, game machines such as slot machines or poker game machines, which pay back coins according to the prize status of the game results, have been very popular and are widely used. A slot machine is described here as one example of a game machine.
After inserting a coin into the slot machine, the player starts the game by operating a start lever, for example. The slot machine causes a plurality of reels (for example, three reels) bearing numerous types of symbols on the circumference thereof to rotate at high speed, and it determines the prize status according to the combination of symbol marks on the reels which appear in prescribed window positions when the reels are stopped. The number of tokens paid out is determined by the combination of symbols when the reels have stopped, in other words, the prize status.
Slot machine prizes include “big jackpots,” where 1000 or more tokens, for example, are paid back, and so-called “small jackpots.” The player plays the slot machine in anticipation of increasing the number of tokens in the player's possession, but since the number of tokens in the player's possession does not increase significantly with “small jackpots,” the player plays the slot machine while hoping for a “big jackpot” that will quickly increase the number of tokens in the player's possession.
In a game machine wherein coins are inserted in order to play a game, a selector is used for sorting the coins inserted and ejecting coins of the wrong shape, such as invalid coins or false coins, and a hopper is used for discharging coins paid back according to the game results. The structure of the selector and the hopper depend on the thickness and diameter of the coins.
Needless to say, there is a difference in size between a 25 cent coin and a dollar coin, for example, and it is not possible to handle both these types of coin using a single type of selector or hopper. However, in a casino, for example, there are many different categories of customer, including, for example, those who want to play games which bet 25 cents a turn (hereafter, called “25 cent rate game”), and those who want to play games which bet 1 dollar a turn (hereafter, “1 dollar rate game”). Therefore, in outlets targeted at a variety of customers, it is necessary to provide, for example, two types of game machine: those taking 25 cent coins, and those taking 1 dollar coins.
The present invention was devised in view of the foregoing, an object thereof being to provide a game machine whereby it is possible to play, for example, a game betting 25 cents a turn and a game betting one dollar a turn, in a single game machine.
In a game machine wherein coins are inserted and a game can be played by placing these coins as a bet, a game machine according to the present invention is characterized in that it allows a game betting a unit value that is different from the value of one of the inserted coins to be played.

Below, the present invention is described with reference to the drawings.
Here is a case where the present invention is applied to a slot machine, which is one example of a slot machine, is described. FIG. 1 is an external view of one embodiment of a slot machine according to the present invention.
In FIG. 1, a slot machine main unit 1 is shown. The front face of a cabinet 2 constituting the entire main unit 1 is provided with windows 3L, 3C, 3R corresponding to the number of reels (in the case of FIG. 1, three reels), for viewing symbols on a set of reels 4L, 4C, 4R located inside the cabinet 2. A start lever 5 for causing the reels 4L, 4C, 4R to rotate when operated by a player is rotatably attached at a prescribed angle on the side face of the cabinet 2.
A coin inlet 6 for inserting coins and a digital display 7 are provided on the lower right side of the windows, 3L, 3C, 3R on the front face of the cabinet 2. The digital display 7 comprises a credit number display 7A for displaying the number of coins currently in credit, and a converted credit number display 7B for displaying the number of coins currently in credit when converted to the current game rate.
Furthermore, on the front face of the cabinet 2 below the windows 3L, 3C, 3R, there are also provided: a spin switch 8 for setting the reels in motion by operation of a push button, which is independent of the operation of the start lever 5; a single bet switch 9 for betting just one of the coins in credit on the game when a push button is pressed once; a maximum bet switch 10 for betting the maximum number of coins which can be bet on a single game when a push button is pressed once; a C/P switch 11 whereby the player can switch between credit and pay out of accumulated coins by operating a push button; and a coin receptacle 13 for collecting coins paid out from a coin pay outlet 12 on the lower front face of the main unit 1 when the C/P switch 11 is operated.
A display panel 14 showing the winning symbol combinations and a prize allocation table, or the like, is provided on the upper front face of the main unit 1. A front door panel 15 is provided, which can be opened and closed with respect to the main unit 1 for the purpose of inspecting and servicing the internal parts of the main unit 1, collecting and supplying coins, and the like. The windows 3L, 3C, 3R for viewing the reels 4L, 4C, 4R located in the main unit 1 are provided in the front door panel 15. A rate changing switch 17 also is provided, and is described in detail later.
FIG. 2 is a diagram illustrating one example of an allocation table marked on the display panel 14 shown in FIG. 1.
In this embodiment of a slot machine, the prize allocation changes according to the number of coins input prior to starting the game (number of coins bet on the game). In FIG. 2, the “1st COIN” column indicates the allocation paid when one coin is inserted, the “2nd COIN” indicates the allocation paid when two coins are inserted, and the “3rd COIN” column indicates the allocation paid when three coins are inserted. The numbers in each of the allocation rows in FIG. 2 indicate the number of one dollar coins paid out.
Furthermore, in the slot machine according to the present invention, it is possible to play a one dollar-rate game, a 25 cent-rate game, or a 50 cent-rate game, while restricting the type of coin which can be inserted to a one dollar coin, as described later. In FIG. 2, the “RATE” column shows the game rate; for example, when the combination of symbol marks shows “777” when two coins are bet in a 50 cent-rate game, then reference is made to the “2nd COIN” column in the “777” and “C50” rows. In this case, 800 one dollar coins are paid out, as shown in FIG. 2.
FIG. 3 is an external view showing in detail the reel viewing window section in the slot machine illustrated in FIG. 1. In FIG. 3, lamps 14 a, 14 a′ are shown, which light up when a coin is inserted, and the player can ascertain the prize status from the combination of symbols “S” stopped on a line 21 illuminated by lamps 14 a, 14 a′. It will be apparent to one of ordinary skill in the art that more than one lamp, and more or less than three reels, may be used on a slot machine according to the present invention.
As described in FIG. 2, in this slot machine, the prize allocation changes according to the number of coins inserted prior to the start of the game (number of coins bet on the game). This is determined in accordance with the flowchart illustrated in FIG. 4, for example, on the basis of the number of coins inserted as detected in the form of an electrical signal by a microswitch, photosensor, or the like, and a determination as to whether or not the start lever 5 or spin switch 8 has been operated. In FIG. 4, as well as causing the display lamps 14 a, 14 a′ to light up, the “BET active” processing also generates an input signal to a microcomputer section described below for reference when determining the number of coins to be paid out when a prize is won.
Optionally, in the type of slot machine in which the prize status is determined by random selection using random numbers, a demonstration is made by unusual lights or sounds or by unusual operations when the randomly selected prize status is a “big jackpot” or when a “big jackpot” is missed by one reel symbol among all the reels, i.e., all but one of the reels are aligned in positions that would correlate to a “big jackpot” result (this condition of two matching symbols out of three reels, or of three matching symbols out of four reels if there are four reels, etc., is referred to as a “one-shy” condition). In one method for making this demonstration, reel lights may be provided on the reverse side of reel belts on which are imprinted the symbols around the reels, and these reel lights, which in conventional slot machines are flashed only when the prize status has been confirmed after all the reels have stopped, are flashed before all the reels stop.
Optionally, a slot machine may randomly select game result conditions from among a plurality of conditions before a plurality of reels, which are rotated at the start of a game, come to a stop. Such a slot machine is characterized by comprising reel light control means for flashing the reel lights on the inside, which illuminate the symbols imprinted on the circumference of the aforementioned plurality of reels when the randomly selected game results correspond to specific conditions, such as “big jackpot” or “small jackpot.” A player is alerted by the reel light control means to the fact that the aforementioned randomly selected game results correspond to the aforementioned specific conditions.
Optionally, the aforementioned reel light control means flash the aforementioned reel lights when there are quasi-specific conditions, including, for example, one or more game result conditions, such as “one-shy”, “two-shy”, and “second game free,” which are similar to the aforementioned specific conditions, among the aforementioned plurality of conditions, and the aforementioned quasi-specific conditions are randomly selected from among the aforementioned plurality of conditions. It will be apparent to one of ordinary skill in the art that this method of random selection of a prize result condition, and of demonstrating the prize result condition selected, may be combined with the systems and methods described herein for selecting a game rate and adjusting the prize probability based on the game rate selected.
FIG. 4 is a flowchart 100 illustrating the selection of lines to activate by lighting up one or more of the lamps 14 a, 14 a′. The selection may be made using a microswitch, a photosensor, or another similar electrical signal-based system for detection of the insertion of a token and determination as to whether or not the start lever 5, or the spin switch 8, or both, have been operated. In the flowchart 100, the line activation process starts at a step 101 indicating conclusion of a prior game. Following the step 101 is a test step 102 that determines whether a coin has been entered. The test step 102 is repeated until a coin is entered. Once a coin has been entered, control passes to a step 104 with one bet active. Following the step 104 is a test step 106 that determines whether the start lever 5 has been pulled. If the start lever 5 has been pulled, then the game proceeds to a game start step 120 and the game starts. Otherwise, a test step 108 determines whether a second coin has been entered. The test steps 106, 108 are repeated until either the start lever 5 is pulled or a second coin is entered. If a second coin is entered, control passes to a step 110 that indicates that two bets are active. Following the step 110, a test step 112 is performed to test whether the start lever 5 has been pulled. If the start lever 5 has been pulled, control passes from the step 112 to the game start step 120. Otherwise, a test step 114 is performed to determine whether a third coin has been entered. The steps 112, 114 are repeated until either the start lever 5 is pulled or a third coin is entered. If a third coin is entered, three bets are active in a step 116. A test step 118 is then performed to determine whether the start lever 5 has been pulled. If the start lever 5 has been pulled, then control passes to the game start step 120. Otherwise, the test step 118 is repeated.
The basic progress of the game after coins have been inserted and the game has been started in this way follows the flowchart shown in FIG. 5.
FIG. 5 is a flowchart 200 illustrating progress of the game once the number of bets active has been determined in accordance with the process shown in FIG. 4 (or by following one of a variety of conventional processes equivalent to that shown in FIG. 4). The game begins at the game start step 120 (of FIG. 4). A reel rotation step 202 follows the start step 120. Following the reel rotation step 202 is a wait step 204. Following the wait step 204 is a prize selection step 206 in which the prize status is selected. Following the prize status selection step 206 is a stop reels step 221 in which the reels are stopped, optionally in response to a player's pressing of stop buttons. After the step 221, control passes to a game end step 224.
In other words, the game is started by operation of the start lever 5 or spin switch 8, the three reels 4L, 4C, 4R rotate, and after a prescribed time period has elapsed, a prize status is selected, the reels 4L, 4C, 4R are stopped automatically based on the selected result, and the current game ends.
When the game is over, prize determination processing is conducted in accordance with the flowchart in FIG. 6, for example, and processing for paying out coins is implemented when a prize has been won. In determining the prize, photoelectric signal components provided for each symbol on the reel are read by photosensors, for example, or in a device where the reels are driven by pulse motors, a signal component is provided in one position on each reel such that a reset pulse is obtained upon each revolution of the reel, thereby allowing it to be determined how many pulse signals have been supplied to the pulse motor after the production of the reset pulse until the reel stops.
The prize status is determined by comparing the combination of the symbols on each reel, in the form of code signals as mentioned previously, with a ROM described below. If a prize has been won, a hopper motor for paying out prize coins is driven to pay out the coins. The coins paid out are counted, for example, by means of a coin counter provided in the coin pay-out chute, and when the prescribed number of coins has been reached, the game is terminated.
FIG. 6 is a flowchart 300 illustrating the determination of the prize when the game is over. Following the game end step 224 (of FIG. 5), control passes to a step 312 in which determination of the prize is made. Following the step 312 is a test step 314 which tests whether a prize was won. If so, control passes to a step 316. Otherwise, control passes to the game over step 101 (of FIG. 4). In the step 316, the coins, or prize tokens, are paid out in the proper amount. Following the step 316 is a test step 318 in which it is determined whether the paying out has been completed. If so, control passes to the game over step 101. Otherwise, control returns to the step 316 and the process is repeated until the game over step 101 is reached.
FIG. 7 is a block diagram of a microcomputer section which controls the slot machine according to the present embodiment.
In FIG. 7, block A marked by the broken line is a main control section comprising a main CPU 50, a ROM 51 and a RAM 52. The ROM 51 contains a table of the aforementioned symbols and their corresponding symbol codes and a table of symbol codes corresponding to prizes and the number of prize coins to be paid out, as well as a prize probability table, and the like, corresponding to the prize status when a prize is awarded for a game that has been played. The RAM 52 provides a random number store for temporarily recording the random numbers sampled after the start of the game, and a memory etc. for temporarily storing data, such as the rotating reel code numbers, symbol numbers, and the like. Preferably, the prize probability changes in accordance with the game rate, which may be changed by means of the rate changing switch. The prize probability may increase as the game rate increases. For example, the prize probability may increase linearly, exponentially, or in some other functional relationship, as the game rate increases.
A clock pulse generator 53 produces, for example, a 4 MHZ pulse and actuates the main CPU 50 by means of this reference pulse, and a divider 54 supplies an interruption pulse of 500 Hz, for example, to the main CPU 50 for the purpose of interrupt execution processing of a prescribed program. A sound generator 55 is driven so as to generate sounds via a speaker 56 in order to enhance the appeal of the game at appropriate times after the start of the game. An LED drive section 57 drives, for example, a seven-segment digital display light-emitting diode 58, and this is used for displaying the number of coins paid out, or the like. The digital display section 7 shown in FIG. 1 may be constituted by a seven-segment digital display light-emitting diode 58 in this way.
Block B marked by the broken line is a reel drive monitoring block. In the present embodiment, the reels 4L, 4C, 4R are driven respectively by pulse motors M1, M2, M3. The motors M1, M2, M3 are rotated by drive pulses from a motor drive section 60 and, for example, the reels 4L, 4C, 4R are rotated such that the symbol on a reel visible through window 3L, 3C, 3R is shifted by one symbol per pulse. Each reel is also constructed such that a reset signal is generated upon each revolution. A detecting block 61 detects this reset signal. In the main CPU 50, the number of drive pulses supplied to the motor after the detecting block 61 has detected a reset signal is counted, thereby enabling the reel symbols visible in the windows 3L, 3C, 3R to be identified.
A prize coin pay-out hopper 70 and a hopper motor drive section 71 also are provided. A coin detecting section 72 detects the insertion of coins prior to the start of a game. A signal for the number of coins paid out from the hopper 70 and a signal for the number of coins inserted from the coin detecting section 72 are transmitted from a count drive section 76 via a Sw input section 75 and the main CPU 50 to the counter or light 77, and the number of coins inserted or paid out is detected, or the display lamps on the active prize line are lit according to the number of coins inserted. When the number of coins inserted reaches three, a lock solenoid 73 is activated to lock the coin inlet. A further switch operating component 78, such as a pause switch, or the like, is operated when the player wishes to suspend a game after inserting coins. A start signal generating section 79 is constituted by the aforementioned start lever 5 or spin switch 8, or the like.
According to the system composition described above, the determination processing relating to the basic progress of the game, as illustrated in the aforementioned flowcharts, can be implemented by means of a prescribed executing program in the main CPU 50.
The composition of the slot machine according to the present embodiment is described further below.
FIG. 8 is a diagram showing the main unit 1 of the slot machine illustrated in FIG. 1, with the front door panel 15 in an open state.
As described previously, windows 3L, 3C, 3R are provided in the front door panel 15, and a reel unit 20 comprising reels 4L, 4C, 4R is provided inside the cabinet 2 in a position facing the windows 3L, 3C, 3R.
A selector 18 is provided for sorting the inserted coins and ejecting coins of the wrong shape, such as invalid coins, false coins, and the like. A hopper 70 also is provided for ejecting coins paid out according to the game result. Coins inserted via the coin inlet 6 are sorted by the selector 18, and if a coin is valid, it is counted as part of the number of inserted coins and then supplied to the hopper, where it is retained. Coins discharged from the hopper 70 are paid out via the coin outlet 12 and collect in the coin receptacle 13.
In the present embodiment, the selector 18 and hopper 70 use one dollar coins. In other words, in a slot machine according to the present invention, it is possible to play a one dollar-rate game, 50 cent-rate game, and a 25 cent-rate game, while restricting the type of coin which can be inserted to a one dollar coin. It will be apparent to one of ordinary skill in the art that the invention may be readily modified to permit play at any rate that is a multiple of $1, such as, for example, a $2 rate game, a $5 rate game, a $10 rate game, etc., or a fraction of $1, such as, for example, a 1 cent rate game, a 5 cent rate game, or a 10 cent rate game, etc.
The player inserts a one dollar coin into the coin inlet 6 in the main unit 1 of the slot machine, and he or she can select the game rate by pressing the rate changing switch 17 illustrated in FIG. 1.
FIG. 9 is a flowchart 950 of processing for changing the game rate. This processing is implemented by the CPU 50 illustrated in FIG. 7, for example. Firstly, following a start step 900, it is determined whether or not the current game rate is a one dollar rate in a step 901. If the current game rate is one dollar, then it is determined whether or not the rate changing switch 17 has been pressed in a step 902, and if it has been pressed, the current game rate is changed to 25 cents in a step 903, and if it has not been pressed, then the current game rate is kept at one dollar in a step 904.
At the rate determination step 901, if the current game rate is not one dollar, then it is determined whether or not the current game rate is 50 cents in a step 905. If the current game rate is 50 cents, then it is determined whether or not the rate changing switch 17 has been pressed in a step 906, and if it has been pressed, the current game rate is changed to one dollar in a step 907, and if it has not been pressed, the game rate is kept at 50 cents in a step 908.
At the step 905, if the current game rate is not 50 cents, then it is determined whether or not the rate changing switch 17 has been pressed in a step 909, and if it has been pressed, the current game rate is changed to 50 cents in a step 910, and if it has not been pressed, the current game rate is kept at 25 cents in a step 911. Following the step 903, the step 904, the step 907, the step 908, the step 910, or the step 911, the game rate determination process ends in a step 920.
FIG. 10 is a flowchart 990 of processing for switching a game according to the game rate. This processing is implemented by the CPU 50 shown in FIG. 7, for example.
Firstly, it is determined whether or not the current game rate set as illustrated in FIG. 9 is a one dollar rate in a step 921. If the current game rate is one dollar, then the number of credits at a one-dollar rate is displayed in figures in the converted credit number display 7B in a step 922. In other words, while the number of credited one dollar coins inserted by the player via the coin inlet 6 is displayed on the credit number display 7A, a number derived by converting the number of coins displayed on the credit number display 7A is shown on the converted credit number display 7A. In the case of a one dollar rate, the number shown on the credit number display 7A and the number shown on the converted credit number display 7B are the same. If a game is played in this state, then by pressing the single-bet switch 9 once, the number shown in the converted credit number display 7B is decremented by one, one dollar is bet on the game, and a one dollar-rate game can be played in a step 923.
In the step 921, if the current game rate is not one dollar, it is determined whether or not the current game rate is 50 cents in a step 924. If the current game rate is 50 cents, the number of credits is displayed in the converted credit number display 7B at a 50 cent rate in a step 925. In other words, while the number of credited one dollar coins inserted by the player via the coin inlet 6 is shown on the credit number display 7A, a number derived by converting the number shown in the converted credit number display 7A at a 50 cent rate is shown in converted credit number display 7B. In the case of a 50 cent rate, the number shown on the converted credit number display 7B is twice the number shown on the credit number display 7A. If a game is played in this state, then by pressing the single-bet switch 9 once, the number shown on the converted credit number display 7B is decremented by one, 50 cents is bet on the game, and a 50 cent-rate game can be played in a step 926.
At the step 924, if the current game rate is not 50 cents, the number of credits is shown in the converted credit number display 7B at a 25 cent rate in a step 927. In other words, while the number of credited one dollar coins inserted by the player via the coin inlet 6 is shown on the credit number display 7A, a number derived by converting the number shown on the credit number display 7A at a 25 cent rate is shown on the converted credit number display 7B. In the case of a 25 cent rate, the number shown on the converted credit number display 7B is four times the number shown on the credit number display 7A. If a game is played in this state, then by pressing the single-bet switch 9 once, the number shown on the converted credit number display 7B is decremented by one, 25 cents is bet on the game, and a 25 cent-rate game can be played in a step 928. Following the $1 rate execution step 923, the 50 cent rate execution step 926, or the 25 cent rate execution step 928 is an end step 930.
When the game is over, if the player wishes the credited coins that have been won to be paid out by the slot machine, then he or she should press the C/P switch 11 shown in FIG. 1. By doing this, a number of one dollar coins equal to the number shown in the credit number display 7A is paid out via the hopper 70 and the coin outlet 12.
In FIG. 5, it was described that the prize status is selected when the game is started. In this prize status selection process, prizes are determined on the basis of prescribed probabilities, but in the present invention, the prize probability used in this selection may also be varied according to the game rate. In other words, if the game rate is low, for instance, a 25 cent rate, then the prize probability can be set to a relatively low value, whereas if the game rate is high, for instance, a one dollar rate, then the prize probability can be set to a high value. By this means, it is possible to provide the player with an advantage when be or she plays a game at a higher game rate. In the embodiment described above, a rate changing switch 17 is provided in a position on the front surface of the front door panel 15 whereby it can be operated by the player such that, provided that there are coins in credit, the player can change the game rate according to his or her own wishes, but the present invention is not limited to this, and the rate changing switch 17 may be located on the rear face of the front door panel 15, for example, such that it can only be changed by employees of the outlet, such as a casino, or the like.
Furthermore, in the aforementioned embodiment, a slot machine accepting one dollar coins was described, but the present invention is not limited to this and it is possible to devise the machine such that coins of a different size to a one dollar coin, or bank notes, or tokens of different sizes or colors representing different monetary values, can be inserted. Coins, bank notes, and tokens will be referred to interchangeably herein as “value units”.
Moreover, in the aforementioned embodiment, a slot machine allowing a one dollar-rate game, a 50 cent-rate game, and a 25 cent-rate game was described, but the present invention is not limited to this and it is possible to offer different game rates to one dollar, 50 cent and 25 cent rates, and it is also possible to switch between two types of game rate, or between four or more types of game rate.
In the aforementioned embodiment, a slot machine was described, but the present invention is not limited to this, and needless to say, it may be applied to any type of game machine which allows a game to be played, whereby coins are inserted and these coins are placed as a bet, such as a poker game machine, or the like.
