Abstract: Open architecture communication systems and methods are provided that allow flexible data transmission between gaming machines and other devices and nodes within a gaming machine network. The gaming machine and other devices employ a communication interface that sends and receives data via a common communication protocol and via common communication hardware. The communication interface and common communication protocol allow data transfer between gaming machines and other network nodes such as gaming service servers, despite the presence of different proprietary gaming machine functions and proprietary communication protocols and despite the presence of various proprietary hardware and proprietary communication protocols relied on by the servers.

Abstract: A central determination gaming system which provides a player a choice in outcomes. In one embodiment of the present invention, upon a player initiating a game play at one of a plurality of gaming terminals in communication with a central controller, the central controller selects a plurality of game outcomes from a pool of game outcomes. The selected game outcomes are communicated to the gaming terminal and the gaming terminal provides one of the selected game outcomes to the player based on at least one choice made by the player regarding the game play. The provided game outcome is prevented from further selections from the pool of game outcomes.

Abstract: Apparatus and methods for administering payouts in gaming machines are disclosed. More particularly, improved techniques for distributing large payouts with minimal interruption of a gaming session at a gaming apparatus are disclosed.

Abstract: A gaming machine displays multiple game outcome presentations to one or more players playing the gaming machine. A player may initiate a new game on the gaming machine while the outcome of a previous game is being presented to the player. For a number of different games, two or more game outcomes may be presented simultaneously to the player on the gaming machine. The game outcome presentations for two or more of the games may appear to interact. However, the game outcomes determined by the gaming machine are independent of one another and do not depend on the game outcome presentation. Many different combinations of games may be played simultaneously on the gaming machine.

Abstract: Disclosed is a gaming system and method designed or configured to provide wins of restricted credits. Restricted credits may be awarded according to the same or a different pay table than cashable credits on the same machine or at the same gaming property. Where separate pay tables are used for restricted and cashable credits, the invention may be implemented with a machine that accepts and pays only restricted credit according to a single, fixed internal payout schedule (“pay table”). Alternatively, the invention may be implemented with a machine that pays restricted credit according to one fixed internal pay table and cashable credit according to another fixed internal pay table. Or, a machine may pay restricted credit according to an external pay table provided by a host system to which the machine is connected.

Abstract: Gaming machines and systems having MRAM and MROM are disclosed. MROMs for storing boot programs and other Read Only code are formed by cutting write connections or not providing PCB socket leads to MRAM write pins, or by using memory hubs to prevent writing to MRAMs. A tale-tale board or other logging device monitoring activities at various components while primary machine power is down records to MRAM, which can be dual ported to the logging device and MGC. Various components can each have dedicated logging devices and MRAMs. One MRAM associated with the brain box replaces both DRAM and NVRAM of regular machine architectures, and is used for dual purposes of regular operational use and as safe storage to facilitate a state recovery. Prioritization of data during the storage process is rendered unnecessary. Another MRAM associated with the back plane board stores data associated with the exterior housing or terminal.

Abstract: Methods and systems for detecting counterfeit cashless instruments are disclosed. A pattern of attempted redemptions or other transactional recordings of gaming machine printed tickets, vouchers or other cashless instruments having identification numbers with valid predictable fields but invalid unpredictable fields can indicate a likely counterfeiting attempt or operation. Occurrences can include a thief or other unscrupulous party discovering which gaming machine printed ticket fields lend themselves to prediction and which do not, and then attempting to guess at some of the randomly generated numbers in hopes of coming up with a valid number or number set. In addition, stored hash numbers can be compared to a hash number generated according to a one-way hash function. A pattern of invalid hash numbers can also indicate a likely counterfeit attempt.

Abstract: Different mechanisms are provided to enable a gaming machine to download files/images, move/copy the files/images from one folder to another without breaking authentication, and resume interrupted file manipulation operations such as move/copy operations and/or download operations which have been interrupted by a power hit. In this way, the technique of the present invention is able to provide a self-diagnostic system for ensuring authenticated, atomic transactions, and for automatically handling detected error conditions. Additionally the technique of the present invention is able to provide a mechanism for seamlessly updating gaming machine components at runtime. This may include, for example, the automatic mounting and/or unmounting of selected games to/from the gaming machine memory during runtime.

Abstract: A disclosed gaming machine presents pachinko games to a player playing the gaming machine. In some embodiments, a player may initiate a new pachinko game on the gaming machine while the outcome of a previous pachinko game is being presented to the player. The wagers on each game may be different. Also, a player may input parameters into the gaming machine that affect the game outcome presentation. For a number of different games, two or more game outcomes may be presented simultaneously to the player on the gaming machine. However, the game outcomes determined by the gaming machine are independent of one another and do not depend on the game outcome presentation. Normally, the game outcomes are determined using a random number generator and a pay table stored in a memory on the gaming machine.

Abstract: A disclosed gaming network provides a method and system for identifying message senders through use of a communication protocol that includes a message field containing message contents and a verification field containing a verification signature. The verification signature is calculated by a message sender utilizing a valuation of the message contents and an identifier value provided by the message receiver.
