When Google announced Android 4.4 KitKat, it also took the wraps off a new contest that was co-sponsored by Hershey. The Android-themed contest, which offers up a Nexus 7 as its grand prize, is now live on Hershey’s website.

To enter, you must purchase a special version of the Kit Kat bar that features the green Android robot on its label. Inside the wrapper is a code that you can enter into a form on Hershey’s website. If you have the right code, you can win a Nexus 7 (1,000 available), a $5 Google Play credit (150,000 available), or a free bag of Kit Kat Minis (20,000 available). As with most contests, you can enter to win without buying a candy bar and adding some inches to your waistline. The contest rules allow you to request a free Game Code by sending a index card to the promotion’s mailing address. You can read the mail-in entry rules below. The no purchase option may be the healthy way out, but it’s not nearly as fun as searching for those green robots in the candy aisle. I know I’ll be on the lookout for these Kit Kat bars and will likely snag a few just because.
