The secret to unlocking the Super Bowl level inside Angry Birds has been hatched by zblanco4, a user over at the Angry Birds Nest, with a little clue to guide the way. Just as Rovio promised, the clue was planted in the Rio ad during Super Bowl - check it out below:

Detailed instructions have been left behind for the rest of us to join in on the fun. The requirements? Not much! As they are:

  1. Open level 13-12 of Ham ‘Em High
  2. Shoot the first Yellow bird anywhere
  3. Now shoot the White bird backwards and drop an egg on the back side of the hill
  4. If you hit the right spot the Golden Egg will pop up!
  5. Once you find the egg you will see the first image below, which opens the Secret Super Bowl Golden Egg level
  6. If you can pass the level you’ll see the second image. Notice that the egg contains the text “Rio”

For those of us on the sidelines, a handy YouTube video has been provided detailing us the Xs and Os on how to tackle this secret and obtain the hidden goodies.
