A Bugdroid checks out the unique winning code on a KitKat package and soon more follow. This was part of a giveaway held by KitKat brand holders (Nestlé's/Hershy) to win prizes.
For those that didn't win, the "Spot the Android" game was mentioned, however this game has not been found. 
There is a chance it could be the post card option in the giveaway, though it is unverified.
This was a precursor to the Android KitKat mini series.
