Shake Shack unveils gamified loyalty offering

Shake Shack is enhancing its guest engagement with app-exclusive offers and a gamified loyalty program. App users may get any size soda for $1. The offer is one of several "Shack Hacks" planned to reward app users.

Also, next week, the company will launch "Challenges," the initial phase of its loyalty program designed to increase customer frequency by encouraging guests to complete tasks and earn rewards.

The first two challenges include:

• Challenge 1: Order any burger on two separate occasions within 30 days to receive $10 off your next visit.
• Challenge 2: Order any BBQ sandwich on two separate visits before Aug. 6 to unlock $5 off your next visit. This challenge promotes the Summer BBQ limited-time offer platform.
