Certification
What is Certification?
Certification is the process by which an independent testing laboratory evaluates and validates that an online slot meets standards for fair play, security, and regulatory compliance. The most recognized laboratories in the industry include eCOGRA, iTech Labs, and Gaming Laboratories International (GLI). A valid certification confirms that the RNG behavior and declared RTP match the specifications submitted for testing.
Role of testing laboratories
Organizations such as eCOGRA, iTech Labs, and GLI evaluate games and platforms on behalf of regulators and operators. Their testing covers whether the random number generator produces outputs consistent with declared distributions, whether the observed RTP aligns with the published figure, and whether bonus mechanics behave as described in the game rules.
Scope of a certification
A certification may cover an individual game, an entire platform, or an operator’s systems. It is commonly required by national gambling authorities as a condition for obtaining an operating license. Certified software may be subject to periodic re-audits or must be re-submitted after any significant update.
What it means for players
A certification does not guarantee winnings, but it confirms that the displayed rules correspond to actual game behavior. In many jurisdictions, certification details are public: the testing laboratory’s seal appears in the casino’s legal footer or on the individual game information page.
