Can I wager on my phone without the BetMGM app?

Yes. However, if you prefer to play on your mobile web browser, you will have to install the Geoguard app on your device. We are required by law to confirm that you are in the state of Massachusetts before accepting wagers; when Geoguard is installed and running on your phone it will confirm your location each time you log in. Geoguard is available in the App Store and the Google Play Store.
