Burger King is giving away 96 a day.
For each 15 minute increment, the Burger King computer randomly picks one time. The individual to enter a code at or directly after that time wins a Kinect bundle.
Sign up, click "send codes" and six codes will be sent to you. You can enter 6 times a day. The code really doesn't matter (as long as it is a valid code); the key is entering the code at the right time.
