What the MGCU Does

  • Licensing — issues and renews operator, vendor, supplier, and key-employee licenses for sports wagering, casinos, and beano.
  • Compliance audits — reviews monthly revenue reports and verifies operators are meeting the 10% adjusted gross revenue tax obligation.
  • Responsible gambling oversight — administers the statewide voluntary self-exclusion program and ensures operators provide required problem-gambling resources.
  • Investigations — handles complaints, suspicious wagering activity, and integrity concerns in cooperation with sports leagues.
  • Geolocation enforcement — confirms operators correctly restrict betting to inside Maine state lines.

Filing a Complaint

Bettors who believe an operator has violated state law — for example, by withholding winnings or failing to honor advertised promotions — can file a complaint directly with the MGCU. Complaints typically require account details, transaction records, and a description of the disputed event.
