Definitions
- the invention relates to gaming communication systems and in particular to progressive gaming communication and control systems.
- progressive systems utilized with gaming machines have a number of significant limitations. For example, in the system where a group of slot machines are connected to a progressive controller which receives coin drop data transmitted from each machine to accumulate "progressive" jackpot values, only a limited number of such jackpot values can be paid by the individual machines.
- video poker progressive systems are currently limited in a number of respects because of their essentially one-way communication arrangements. These video poker systems typically display a maximum of three jackpot values corresponding to the top three winning hands e.g., royal flush, straight flush and four of a kind, and typically use a separate line from the progressive controller to each game to transmit each jackpot value or alternatively a single line with a variable number of pulses representing each jackpot value.
- FIG. 1 a portion of a gaming machine 10 in this case a video poker machine such as the Bally 5000 Plus Video Poker Machine, which can be used with a progressive gaming and control system.
- a video display 12 is used as shown in FIG. 1 to provide a display of a typical five card draw poker hand comprising five cards 14a-14e along with a table 16 which displays the current values of progressive jackpots for five winning hands: royal flush, straight flush, four of a kind, full house and a flush.
- a portion 18 of the display 12 is used to indicate to the player that the progressive jackpots shown in table 16 are available upon the insertion of a sixth coin.
- the video display 12 also provides an indication at 20 of the number of coins paid by the machine 10 along with an indication at 22 of the number of credits remaining to the player for credit play.
- a group of control buttons indicated generally at 23 are used by the player to control the machine 10 in the conventional manner and a coin slot 24 is used by the player to insert coins into the machine.
- Coin payouts are provided to the player via a hopper 25.
- FIG. 2 Illustrated in block diagram form in FIG. 2 is the preferred embodiment of a progressive game control and communication system utilizing a single communication unit 26.
- each of a group of up to 32 gaming machines 10 are individually connected to a RS232 interface 28 in the communication unit 26 by a bi-direction communication line 30.
- a commercially available progressive controller such as the Mikon Link Progressive Controller is connected to a RS422 interface 32 in the communication unit 26 by a bi-directional communication line 34.
- the progressive controller 30 can be used to control a LED or video display 36 over a line 38 to display progressive jackpot values as is typically done in casino environments.
- a microcomputer such as the Zilog Z-80 along with associated circuit components including RAM and ROM memory as indicated by 40 is used to control the operation of the communication unit 26. Functional connection of the optically isolated RS232 and RS422 interfaces 28 and 32 to the computer 40 is illustrated by a pair of lines 42 and 44.
- Each of the lines 30 from the communication unit 26 to the games 10 includes: a first data transmission line to transmit data in serial form from the communication unit 26 to the game 10; a second data line to transmit data in serial form from the game 10 to the communication unit 10; an enable line to transmit an enable signal from the communication unit 26 to the game 10; and a connect line to transmit a connect signal from the game 10 to the communication unit 26.
- the first type of data represents the values of the progressive jackpots that are to be displayed on the table 16 of the game display 12 which is broadcast to all of the games 10 by the communication unit 26.
- this message can include an ASCII character such as a "B" to indicate that it is a broadcast message; an ASCII "9" to indicate that the message represents jackpot values; and five, seven byte packets containing the values to be displayed.
- each game 10 can transmit an acknowledgment message to the communication unit 26 indicating that the message has been properly received; although because these jackpot values are transmitted every second in the preferred embodiment, this acknowledgment is not used.
- the second type of data represents the value of one of the progressive jackpots and is transmitted to a particular game 10 after the communication unit 26 has received a message from that game that a specific jackpot has been hit, e.g., a royal flush.
- This data message will include: an ASCII "L” to indicate that the message represents the value of a jackpot; an ASCII "0-7" to indicate which jackpot and a data portion representing the current value of that jackpot.
- the game 10 will transmit an acknowledgment message to the communication unit 26 and then either pay the jackpot value through the hopper 25 or flash an appropriate message so that the jackpot can be paid by hand.
- the second data line in line 30, as previously indicated, is used to transmit various data messages from the games 10 to the communication unit 26.
- each game 10 will transmit an eight byte identification code where the first character is an ASCII "I" to the communication unit 26 to identify itself.
- the game 10 After sufficient coins have been inserted or credits bet for jackpot play, the game 10 will transmit a coin-in message which includes: an ASCII "C” to indicate that this is a coin-in message; and ASCII "0-7" to indicate which jackpot is being played or an ASCII "8” to indicate that all jackpots displayed in table 16 are being played; two ASCII characters representing the number coins or credits bet at a first progressive rate; and two ASCII characters representing the number of coins or credits bet at a second progressive rate.
- the data message transmitted to the communication unit 26 includes an ASCII "J” to indicate a hit message and an ASCII "0-7" to indicate which of the jackpots listed in table 16 has been hit.
- a release message consisting of an ASCII "R" and an ASCII "0-7" indicating which jackpot has been released is transmitted to the communication unit 26.
- the communication unit 26 will transmit an acknowledgment that the message was properly received to the game 10 in response to each of the above described messages.
- the progressive controller 30 communicates with the communication unit 26 over the line 34.
- Messages sent by the progressive controller 30 to the communication unit 26 include a polling message to request any pending traffic that the communication unit 26 may have.
- the progressive controller 30 can transmit a jackpot value information message which includes: an ASCII "B" which indicates that jackpot value information is to follow; an ASCII number 0-7 indicating the particular jackpot in table 16; and a series of bytes containing the current value of that jackpot.
- the progressive control 30 will also transmit a jackpot winner message, in response to a jackpot request message from the communication unit 26, and can include: the address in ASCII "01-32" of the game with the winning jackpot; and ASCII "L” if the jackpot requires a game lockup; an ASCII number "0-7" identifying the jackpot, for example from table 16, which has been won; and ten ASCII bytes that indicates the value of this particular jackpot.
- the communication unit 26 typically transmits a number of different messages to the progressive unit 30.
- One such message is a coin-in message which represents the number of coins or credits input into the game 10 since the last coin-in message was set to the progressive controller 30.
- One of the functions of the computer 40 in the communication unit 26 is to accumulate this coin-in data from the games as discussed above.
- the coin-in message can include: an ASCII "C” to indicate that this is a coin-in message; and ASCII value of "01-32" to identify the last game to accept a coin or a credit; an ASCII value of "0-7" to indicate that the coins are for a specific jackpot or a value of "8” to indicate that the coins or credits are for all of the jackpots; two ASCII characters to indicate the number of coins bet at a first progressive rate; and two ASCII characters to indicate the number of coins bet at a second progressive rate.
- This message is usually sent in response to the poll message from the progressive unit 30 and is used by the progressive controller 30 to increment the various jackpot values shown in Table 16.
- a jackpot win message is another of such messages transmitted over line 34 and includes the address in ASCII "01-32" of the game 10 in which the jackpot win occurred; an ASCII "J” indicting that this is a jackpot win message; an ASCII character from "0-7" indicating which jackpot from table 16 has been won and is also sent in response to a poll message from the progressive controller 30.
- the communication unit 26 does not have any information to transmit to the progressive controller 30, it will in response to the poll message, transmit a no traffic message which includes an ASCII "N.”
- Another message termed an application acknowledgment, is transmitted in response to the poll message and results from the above described jackpot win message to confirm that this instruction is received and executed properly.
- This message includes the ASCII id (01-32) of the game 10 providing the payout and an ASCII "00” if the jackpot is to be paid by the hopper 25 along with an ASCII "Ack” to acknowledge receipt of the message.
- the previously mentioned enable and connect lines in line 30 also perform operative functions with respect to the progressive control and communication system.
- a signal on the connect line serves to provide the communication unit 26 with notice that the game 10 is connected to the communication unit 10.
- the actual identification of the game 10 is transmitted to the communication unit 26 on one of the data lines upon power up as described above.
- the enable line is used by the communication unit to enable the operation of the game 10 to which it is attached.
- the communication unit 26 can be programmed, for example, by DIP switches, to disable operation of the games 10 under certain circumstances by utilizing the enable line.
- the enable line can be used to disable or lock-up all of the machines 10 until this jackpot has been paid. Also, if there is a fault in the progressive controller 30 or communication between the progressive controller 30 and the communication unit 26, the communication unit 26 can use the enable line to disable all of the games 10 to stop play until the fault is remedied.
- the computer 40 of the communication unit 26 facilitates operation of the progressive system of FIG. 2 by accumulating coin drop information from each of the gaming machines 10 in its memory until the communication unit 26 is polled by the progressive controller 30.
- This arrangement permits a progressive system having a large number of gaming machines 10, up to 32 in the embodiment of the invention described above, where a large number of progressive jackpots, up to eight, can be managed effectively at high speed. Also, by using bi-directional communication with the appropriate acknowledgments between gaming machines 10 and a progressive controller 30,the reliability and security of the progressive system is substantially enhanced.
