Play daily until 10/31. There are quite a lot of free food and drink prizes with no purchase necessary to redeem them. You have to use the Carl’s Jr. app and play the game (press and hold on the car to slide left and right) although the app just launches a webpage.
Note: The rewards don’t show up automatically in the app, you have to redeem the promo code that you get in the winning confirmation email.
