Since BetMGM Casino is licensed and regulated in the states where it operates, it must comply with all rules and regulations related to fairness and testing. The return-to-player percentages for each game are rigorously maintained, as are other elements of gameplay, with everything regularly subjected to audits by regulators. As with any brick-and-mortar casino, BetMGM would not be able to keep its license to operate without proving the integrity of the games it offers.
