When an online casino is labeled a Certified Casino, the platform has been tested and verified by independent regulatory bodies or testing agencies to ensure fair play, security, and compliance with legal standards. The certification confirms that the games use genuine Random Number Generators (RNGs), personal and financial data are protected, and the operator adheres to responsible gambling practices. Certified casinos are typically licensed by respected authorities like the UK Gambling Commission, MGA, or others, giving players confidence that the casino is trustworthy, transparent, and operates legally.
