I was asked to devise a mechanism to increase in-store time and money spent by customers.
"adi-dash" is a mobile/in-store competition. The user takes a waiting number on their cellphone, and has to wait until the number is (possibly) called at the store. They then can spend a fixed amount of money in a very short time.
This solves the problem in two ways. The user is required to wait for their number to be called, increasing dwelltime. However, the limited amount of time available in case of a win makes it necessary to familiarize themselves with the prices and offers of all products. When their number (most likely) is not called, there's a high chance that they want to take *something* home that they have discovered.
