The present invention provides an architecture and method for a gaming-specific platform that features secure storage (354) and verification (366) of game code and other data, provides the ability to securely exchange data with a computerized wagering gaming system, and does so in a manner that is straightforward and easy to manage. Some embodiments of the invention provide the ability to identify game program code as certified or approved, such as by the Nevada Gaming Regulations Commission or other regulatory agency. The invention provides these and other functions by use of encryption (216), including digital signatures (220) and hash functions (210) as well as other encryption methods.

Encryption in a secure computerized gaming system

A disclosed gaming machine is designed to execute a modular gaming software architecture. A plurality of gaming software modules may be loaded into RAM on the gaming machine and executed to play a game of chance. Many of the gaming software modules are designed to communicate via application program interfaces so that the logic in many of the gaming software modules may be designed independently of each other. In particular, the modular gaming software architecture allows a game flow software module used to generate a game of chance on the gaming machine to be decoupled from a game presentation software module used to present the game chance. Thus, a group of games may be designed where the games share a common game flow software module but use different game presentation software modules to change the look and feel of the game.

Game development architecture that decouples the game logic from the graphics logic

A method of playing a slot machine game in which a player wagers upon one or more symbols and then collect awards for combinations of two or more symbols wagered upon appearing in adjacent to each other in the symbol matrix. The slot machine game may also provide a symbol repositioning feature in which one or more symbols are moved from their original positions to other positions in the symbol matrix.

A disclosed gaming machine is designed to execute a modular gaming software architecture. A plurality of gaming software modules may be loaded into RAM on the gaming machine and executed to play a game of chance. Many of the gaming software modules are designed to communicate via application program interfaces so that the logic in many of the gaming software modules may be designed independently of each other. In particular, the modular gaming software architecture allows presentation state logic to be decoupled from implementations of presentation components, such as graphical, audio and gaming device components, used in a presentation of the game of chance on a gaming machine.

Decoupling of the graphical presentation of a game from the presentation logic

A transformation engine that enables content and information to be transformed from one format, a source format, to a format that is compatible with the requesting device, a destination format. Advantageously, various device types can access and share content via a network without concern as to the original format of the content. When a client device provides a request for content, the transformation engine identifies delivery characteristics of the client device, and identifies a source for the requested content. The transformation engine then transforms the source formatted content into a format identified through a best fit analysis of the delivery characteristics of the device.

Content management and transformation system for digital content

A utility program for software development generates a synchronized set of translation modules for application program interfaces in a emulated platform. The utility builds the translation modules from iterated function templates having generalized function code, exception templates with special-purpose code, and types templates for converting data types from the emulated platform.

Program-interface converter for multiple-platform computer systems

A utility program develops and updates an API-translation layer of an emulator for running programs written for one platform on another platform. This speeds the development of code such as operating-systems upgrades, where the API set can change frequently. The utility builds a module for each API from a set of templates to execute the module's function on the other platform. Generalized function templates iterate through API functions. Exception templates can override the generalized templates in specific cases. Types templates convert individual arguments of the API. Code templates contain code for incorporation into a number of other templates.

Interface conversion modules based upon generalized templates for multiple platform computer systems

A single program loader loads program modules for multiple platforms in an emulation environment. A name list has entries each containing the name of a module for one platform and the name of a corresponding module for another platform. The loader identifies first-platform modules in a load list, and substitutes the corresponding module for the other platform. Modules referenced in any loaded module are added to the load list recursively.
