All reputable online casinos are powered by well-known and secure online casino software that creates games that are completely random and fair. Additionally, online casinos have their games tested for fair play and randomness by external, independent auditors like eCORGA , BMM and TST that ensure casino fans are playing in a fair and safe online casino gaming environment. TST in particular rigorously tests the randomness of the random number generator, while eCORGA also makes sure that casinos deliver fair payout percentages.
