M life, MGM Resorts International's customer loyalty program, has announced new relationships with Visa Inc., a global payments technology company, and Topguest, a product of Switchfly, Inc., which enables loyalty programs to reward members for sharing on social networks.

M life rewards members with Tier Credits for social engagement and with offers when using their enrolled Visa cards. With Visa's real-time messaging technology, M life Mobile Offers provide personalized offers from MGM Resorts' destinations in Las Vegas for Visa account holders who opt into the program. Visa account holders may visit www.visa.com/mlife and enroll their eligible Visa accounts and mobile phone numbers. Once enrolled, members may receive offers via SMS text to their mobile phones.

For example, when a member makes a hotel reservation online or via phone for Excalibur using his or her enrolled Visa account, he or she may receive an SMS text with a special show ticket offer and a link for advance purchase. And, while shopping in Las Vegas with their enrolled Visa cards, members may receive offers relevant to their interests. M life Mobile Offers will launch later this year at Beau Rivage in Biloxi, Miss.; Gold Strike in Tunica, Miss.; and MGM Grand Detroit.

Via Topguest, M life now rewards members for sharing their MGM Resorts' experiences via social networks. Members who link their social media accounts will receive 500 M life Tier Credits when they virtually check in with Facebook Places or Foursquare, post a location-tagged tweet to Twitter, or share an Instagram photo from participating MGM Resorts' venues on the Las Vegas Strip; Biloxi, Miss.; Tunica, Miss.; or Detroit. Members can earn 500 Tier Credits per resort, per day.

In Las Vegas, they can earn up to 6,000 credits if they visit all 12 participating properties in a day, allowing them to advance more quickly to the next Tier Level, with each level providing additional benefits. A maximum of 7,500 Tier Credits per quarter, with a possible total of 30,000 each year, may be earned through social engagement.
