  • Some preferred intelligent gaming tables of the present assignee are implemented with special features and/or additional circuitry that differentiates them from general-purpose computers (e.g., desktop PC's and laptops).
  • Intelligent gaming tables are highly regulated to ensure fairness and, in some cases, intelligent gaming tables may be operable to dispense monetary awards. Therefore, to satisfy security and regulatory requirements in a gaming environment, hardware and software architectures may be implemented in intelligent gaming tables that differ significantly from those of general-purpose computers.
  • a description of intelligent gaming tables relative to general-purpose computing machines and some examples of the additional (or different) components and features found in intelligent gaming tables are described below.
  • a fault or a weakness tolerated in a PC may not be tolerated in an intelligent gaming table because in an intelligent gaming table these faults can lead to a direct loss of funds from the intelligent gaming table, such as stolen cash or loss of revenue when the intelligent gaming table is not operating properly.
  • a first difference between intelligent gaming tables and common PC based computers systems is that some intelligent gaming tables may be designed to be state-based systems.
  • a state-based system the system stores and maintains its current state in a non- volatile memory, such that, in the event of a power failure or other malfunction the intelligent gaming table will return to its current state when the power is restored. For instance, if a player was shown an award for a table game and, before the award could be provided to the player the power failed, the intelligent gaming table, upon the restoration of power, would return to the state where the award is indicated.
  • PCs are not state machines and a majority of data is usually lost when a malfunction occurs. This requirement affects the software and hardware design on an intelligent gaming table.
  • PC based computer systems is that for regulation purposes, various software which the intelligent gaming table uses to generate table game play activities (such as, for example, the electronic shuffling and dealing of cards) may be designed to be static and monolithic to prevent cheating by the operator of intelligent gaming table.
  • various software which the intelligent gaming table uses to generate table game play activities may be designed to be static and monolithic to prevent cheating by the operator of intelligent gaming table.
  • one solution that has been employed in the gaming industry to prevent cheating and satisfy regulatory requirements has been to manufacture an intelligent gaming table that can use a proprietary processor running instructions to generate the game play activities from an EPROM or other form of non-volatile memory.
  • the coding instructions on the EPROM are static (non-changeable) and must be approved by a gaming regulators in a particular jurisdiction and installed in the presence of a person representing the gaming jurisdiction.
  • any changes to any part of the software required to generate the game play activities can require a new EPROM to be burnt, approved by the gaming jurisdiction and reinstalled on the intelligent gaming table in the presence of a gaming regulator.
  • an intelligent gaming table must demonstrate sufficient safeguards that prevent an operator or player of an intelligent gaming table from manipulating hardware and software in a manner that gives them an unfair and some cases an illegal advantage.
  • the intelligent gaming table should have a means to determine if the code it will execute is valid. If the code is not valid, the intelligent gaming table must have a means to prevent the code from being executed.
  • the code validation requirements in the gaming industry affect both hardware and software designs on intelligent gaming tables.
  • a third important difference between intelligent gaming tables and common PC based computer systems is the number and kinds of peripheral devices used on an intelligent gaming table are not as great as on PC based computer systems.
  • intelligent gaming tables have been relatively simple in the sense that the number of peripheral devices and the number of functions the intelligent gaming table has been limited.
  • the functionality of intelligent gaming tables were relatively constant once the intelligent gaming table was deployed, i.e., new peripherals devices and new gaming software were infrequently added to the intelligent gaming table.
  • This differs from a PC where users will go out and buy different combinations of devices and software from different manufacturers and connect them to a PC to suit their needs depending on a desired application. Therefore, the types of devices connected to a PC may vary greatly from user to user depending in their individual requirements and may vary significantly over time.
  • intelligent gaming tables still have unique device requirements that differ from a PC, such as device security requirements not usually addressed by PCs.
  • monetary devices such as coin dispensers, bill validators and ticket printers and computing devices that are used to govern the input and output of cash to an intelligent gaming table have security requirements that are not typically addressed in PCs. Therefore, many PC techniques and methods developed to facilitate device connectivity and device compatibility do not address the emphasis placed on security in the gaming industry.
  • a number of hardware/software components and architectures are utilized in intelligent gaming tables that are not typically found in general purpose computing devices, such as PCs.
  • These hardware/software components and architectures include but are not limited to watchdog timers, voltage monitoring systems, state- based software architecture and supporting hardware, specialized communication interfaces, security monitoring and trusted memory.
  • a watchdog timer may be used in International Game Technology (IGT) intelligent gaming tables to provide a software failure detection mechanism.
  • ITT International Game Technology
  • the operating software periodically accesses control registers in the watchdog timer subsystem to "re-trigger" the watchdog. Should the operating software fail to access the control registers within a preset timeframe, the watchdog timer will timeout and generate a system reset.
  • Typical watchdog timer circuits include a loadable timeout counter register to allow the operating software to set the timeout interval within a certain range of time.
  • a differentiating feature of the some preferred circuits is that the operating software cannot completely disable the function of the watchdog timer. In other words, the watchdog timer always functions from the time power is applied to the board.
  • IGT gaming computer platforms preferably use several power supply voltages to operate portions of the computer circuitry. These can be generated in a central power supply or locally on the computer board. If any of these voltages falls out of the tolerance limits of the circuitry they power, unpredictable operation of the computer may result. Though most modern general-purpose computers include voltage monitoring circuitry, these types of circuits only report voltage status to the operating software. Out of tolerance voltages can cause software malfunction, creating a potential uncontrolled condition in the gaming computer. Intelligent gaming tables of the present assignee typically have power supplies with tighter voltage margins than that required by the operating circuitry. In addition, the voltage monitoring circuitry implemented in IGT gaming computers typically has two thresholds of control. The first threshold generates a software event that can be detected by the operating software and an error condition generated.
  • This threshold is triggered when a power supply voltage falls out of the tolerance range of the power supply, but is still within the operating range of the circuitry.
  • the second threshold is set when a power supply voltage falls out of the operating tolerance of the circuitry. In this case, the circuitry generates a reset, halting operation of the computer.
  • IGT slot machine game software One method of operation for IGT slot machine game software is to use a state machine. Different functions of the game (bet, play, result, points in the graphical presentation, etc.) may be defined as a state. When a game moves from one state to another, critical data regarding the game software is stored in a custom non-volatile memory subsystem. This is critical to ensure the player's wager and credits are preserved and to minimize potential disputes in the event of a malfunction on the gaming machine.
  • the gaming machine does not advance from a first state to a second state until critical information that allows the first state to be reconstructed has been stored. This feature allows the game to recover operation to the current state of play in the event of a malfunction, loss of power, etc that occurred just prior to the malfunction.

  • Devices which meet or exceed the above criteria may be referred to as "fault-tolerant” memory devices, whereas it is which the above criteria may be referred to as “fault non-tolerant” memory devices.
  • battery backed RAM devices may be configured or designed to function as fault-tolerant devices according to the above criteria, whereas flash RAM and/or disk drive memory are typically not configurable to function as fault-tolerant devices according to the above criteria. Accordingly, battery backed RAM devices are typically used to preserve gaming machine critical data, although other types of non- volatile memory devices may be employed. These memory devices are typically not used in typical general-purpose computers.
  • the gaming machine is configured or designed to store critical information in fault-tolerant memory (e.g., battery backed

  • Security monitoring circuits detect intrusion into an IGT intelligent gaming table by monitoring security switches attached to access doors in the intelligent gaming table cabinet. Preferably, access violations result in suspension of game play and can trigger additional security operations to preserve the current state of game play. These circuits also function when power is off by use of a battery backup. In power-off operation, these circuits continue to monitor the access doors of the intelligent gaming table. When power is restored, the intelligent gaming table can determine whether any security violations occurred while power was off, e.g., via software for reading status registers. This can trigger event log entries and further data authentication operations by the intelligent gaming table software.
