If you're just hanging out playing Angry Birds in the living room while the Super Bowl is on, be sure to look up while the commercial for the animated film Rio is playing. Hidden in the ad will be a code for a downloadable Angry Birds levels (though it's not been specified if it will be compatible with all versions of the game.)

Users who find the code in the ad (which will be available on YouTube later), and then complete the level will be entered to win a trip to the March 22 premiere of Rio -- the same day the Angry Birds Rio promotional game is released. No details about the level itself have been released, but we can confirm it involves slingshotted spheroid birds launched at rickety structures.
