Grocer Kroger will test an app from software company Earn & Play that rewards shoppers with cash and discounts for playing games during grocery store visits.

Customers will be able to open the app when they go shopping and select a particular aisle or product. The app will then ask the user a series of questions aimed at ascertaining what makes that product or brand noteworthy.

Shoppers will be able to choose between a cash prize for playing the game or product discounts.
