During the Super Bowl, a commercial hinted at an Angry Birds secret. Those who figured out the secret were rewarded with a football-shaped golden egg. The hidden level for that golden egg? A teaser for the upcoming Angry Birds Rio. For those that missed the commercial, a screenshot can be found after the break, as well as the full video for how to unlock the golden football egg, and the level you’ll receive as a reward. Kudos to @AndroidThrasher for the screenshot and scarbzscope for the video!
