The Michigan Gaming Control Board (MGCB) is continuing its crackdown on illegal gambling with a further 12 cease-and-desist letters issued to offshore gambling operators.

The latest enforcement action involves twelve sites that were found to be unlawfully offering online casino-style games and sports betting to Michigan residents in violation of state law.

The cease-and-desist letters were sent to the operators of 31 Bets Casino, Betnuvo, BetPhoenix, Booty.bet, Jackpotter, Kings Chance Casino, Mybitcoin Casino, Starbets, The Virtual Casino, This Is Vegas, Vegas Strip Casino, and xWin90.

“Illegal online gambling sites operate without oversight, putting players at risk and undermining Michigan’s secure, regulated marketplace,” said MGCB executive director Henry Williams. “We will continue to take relentless, decisive action to prevent unlicensed operators from targeting Michigan residents and ensure that all gaming is conducted lawfully and responsibly.”

Entities that ignore cease-and-desist directives may face additional enforcement measures by Michigan authorities.
