What Is GLI (Gaming Laboratories International)?

The largest accredited testing laboratory in regulated gaming

In short:

GLI (Gaming Laboratories International) is the largest accredited testing laboratory in regulated gaming. It certifies games, platforms, and operators across more than 480 jurisdictions and authors widely cited technical standards including GLI-19 (online gaming) and GLI-33 (event wagering).

What GLI does

GLI is a global testing laboratory founded in 1989 and headquartered in Lakewood, New Jersey. It provides certification services to game developers, platform vendors, and operators across both land-based and online gaming. Its scope covers RNG certification, RTP audit, platform compliance, technical standards authorship, and ongoing operator audit.

GLI is one of a small group of accredited laboratories alongside eCOGRA, BMM Testlabs, and iTech Labs. It has the largest geographic footprint, with offices in major regulated markets including the US, Europe, Asia, and Australia.

Key GLI standards

GLI-19 is the technical standard for online gaming systems, covering RNG, game logic, security, and customer-facing requirements. It is referenced or adopted by regulators across multiple online markets. GLI-33 covers event wagering and sportsbook systems. GLI-11 covers gaming devices in land-based environments.

Each standard goes through periodic revision as technology and regulation evolve. Adoption varies by jurisdiction, with some regulators adopting GLI standards directly and others adapting them into local technical requirements.

Why GLI matters in B2B

For game developers and platform vendors, GLI certification is the most widely accepted ticket to market. For operators, GLI-certified products signal that the underlying software has passed an externally validated standard. For affiliates and review publishers, GLI involvement is an editorial trust signal.
