The international casino game industry has adopted G2S (game to systems) protocol for the futurecommunication standards between slot machines and gaming hosts. G2S protocol uses the internet protocols andXML message format. Not simply G2S protocol replaces the SAS protocol currently in use but with manylimitations, but provides diverse application and business chances to the casino industry. In this paper, weintroduce the overview of technical features of G2S system, and describe our design and implementationexperience of core G2S protocol engine for slot machine devices. The G2S engine provides key protocol stack ofG2S (HTTP, XML, and SOAP) and runtime services, using open source softwares and custom classes. Theprotocol compatibility of the implemented G2S engine is confirmed against an openG2S host softwarecontributed by IGT. Also the measured memory size and perfroamcne is compact enough for typical slotmachine hardware specification.
