Maryland Online Sportsbook Reviews & Ratings
Using sports betting apps in Maryland is convenient and legal for residents aged 21 and older. Maryland based apps do require geolocation technology to ensures users are physically within state borders when placing bets. Some people think of this as an invasion of privacy and prefer the offshore sports betting sites that do not require bettors to download a tracking app on their phones.
