Sometimes a advertising campaign with the simplest audience engagement can generate the best results. A great example of this is Vodaphone’s “Pixel Hunt” game created by Jung Von Matt/Alster.  The game was designed to promote the new LG Optimus phone and its 5 megapixel camera in Germany. Game play is simple, you click on pixels to eliminate them, and if you are lucky you could instantly win one of one hundred phones hidden behind a pixel in the image.

In one month, all 5 million pixels were clicked out by over 300 thousand participants that signed into the site to play. That is some pretty serious usage, that was generated with minimal promotion, and viral spread.
