Get ready to win big with Starbucks‘ newest promotion, the Starbucks Summer Games. Starting July 21st – August 23rd, customers who download the app and sign up as a Starbucks Reward member can participate. The Starbucks Summer Games website has a game, similar to pinball, where you can potentially win prizes depending on how well you do. The first game is free but to continue earning prizes/points you will have to purchase something from the coffee chain during the sweepstakes period. For a full breakdown on their prizes click HERE.
