A Random Number Generator (RNG) is an algorithm designed to generate a sequence of numbers or outcomes that cannot be predicted. It is commonly used in video and casino games to ensure fairness and unpredictability in the results. To verify the integrity of an RNG, third-party testing services conduct thorough evaluations, including ongoing assessments of RNG performance, game payout verification, security audits, and more. If the RNG passes these tests, it receives certification, affirming its randomness and fairness. This certification is crucial for maintaining the trust and confidence of players in the gaming system.
