Michigan’s gambling regulator has clamped down on a further 10 unlicensed online gaming sites for serving players in the state.

The Michigan Gaming Control Board (MGCB) has sent 10 cease-and-desist letters to illegal offshore websites operated by Apex Dynamics, who are based in Belize.

With the latest enforcement action, the MGCB has issued cease and desist letters to 26 illegal online operators this year.

The sites facing regulatory action include Aladdin’s Gold Casino, All Star Slots, Buzz Luck, Club World Casinos, CryptoReels, High Noon, Lucky Red Casino, Manhattan Slots Casino, ReelSpin Casino and Slotter Casino.

“The Gaming Control Board’s relentless dedication to maintaining the integrity of Michigan’s gaming industry drives our efforts,” said MGCB executive director Henry Williams. “We will continue to take strong action to shut down illegal operations that undermine trust in Michigan’s legal gaming system.”

Michigan’s regulated online gaming and sports betting market generated monthly revenue of $268.5 million in February, a 23 per cent year-on-year improvement.

Gross iGaming revenue was up by 18 per cent to $222.5 million, while online sports betting gross revenue increased by 51 per cent to $46.0 million.
