Roar Digital has launched the BetMGM online gaming and betting app in the state of New Jersey, a rebranding of its original PlayMGM app that was introduced in 2017.

Roar Digital, the joint venture created by MGM Resorts and GVC Holdings, will incorporate the new GVC sportsbook platform into the app and will serve as the core mobile platform for future state rollouts.

The rebrand enables customers to play traditional MGM Resorts casino and poker games, along with the ability to place an expanded range of pre-match and in-play bets on professional and collegiate football, MLB, MLS, NBA and NHL games, among other sporting events.

"Today's an exciting day as we launch the rebranded and upgraded BetMGM app in New Jersey," said Roar Digital chief exec Adam Greenblatt.

"We're thrilled to give our customers bigger and bolder opportunities to enjoy the games and unique experiences that BetMGM will provide as the professional and collegiate football seasons get underway. We believe our product takes in-game entertainment to the next level."

Upgraded features in the app include an early cash out function, a one wallet system allowing movement of funds across customer accounts, the ability to track bets in real time, and daily boosted bets and promotions across all major sports.

MGM's president of interactive gaming, Scott Butera, commented: "The mobile gaming industry's future is on a steep incline, and we are harnessing best-in-class mobile technology from Roar Digital, powered by GVC.

"We expect this significant upgrade to our mobile experience to complement MGM's proven retail presence and allow us to immediately compete in New Jersey and additional states where mobile gaming is approved."

GVC Holdings chief executive Kenneth Alexander added: "The combination of the power of MGM's brand, alongside GVC's state-of-the-art technology and online sports-betting expertise, will ensure that the BetMGM offering is at the forefront of the US sport-betting opportunity."

The BetMGM app is currently available for download on the App Store.
