Certification and Legality
GLI (Gaming Laboratories International) has created a standard (GLI #21) which includes requirements and definitions for Server Centric Gaming systems, referred to as Client-Server Systems (CSS). GLI differentiates between Server Based Gaming Systems (SBGS) and Server Supported Gaming Systems (SSGS). GLI defines SBGS as “The combination of a server and client terminals in which the entire or integral portion of game content resides on the server.” SSGS is defined as “The combination of a server and client terminal(s) which together allow the transfer of the entire control program and game content to the client terminal(s)…”
GLI certifies SBG and SSG systems according to the GLI #21 standard, something which is a requirement by many operators and jurisdictions for them to consider and allow such systems. Currently SBG systems are allowed in several countries and US states, both through GLI certification and local legislation.
