Auditing is an important part of ensuring fairness in all forms of gambling, including sweepstakes casinos. Audits involve verifying that games are operated according to the rules and regulations set out by the casino, as well as ensuring that payouts are made accurately and in a timely manner. To be compliant with international standards, sweepstakes casinos must have their games regularly audited by third-party auditors who have no affiliation with the casino itself.
