Drake and Lil Wayne might be changing the game with the set up of their interactive Drake vs. Lil Wayne Tour, and accompanying app, which allows fans to choose a winner between to the two "battling" rappers each night of the concert. Now two shows deep, Birdman Jr. is 2-0 against his protégé. Still confused about how all this works? The duo recently dropped a video to give fans run down of how the app functions, and also use the face time for a little friendly trash talk.

The tour plans on hitting 31 cities throughout the months of August and September including New York City, Chicago, Atlanta, San Francisco, Houston, Dallas and Los Angeles. On opening night, the duo performed the new Carter V single "Grindin'" for the first time.

Peep the tutorial, above.
