Developed in conjunction with Wonderful Pistachios' inhouse agency, it's a browser-based game entitled The Hunt for the Golden Pistachio.
The first two levels open for everyone to play, while the remaining three levels are only accessible by entering a 'Get Crackin' code found on specially marked bags of Wonderful Pistachios, or sharing aspects of the game via Facebook and Twitter.
These levels contain hidden in-game Golden Pistachios that may result in real-life rewards, ranging from free pistachios and Angry Birds plush toys to $25,000 cash. These are only available to US residents over the age of 18.
This element will run until 31 December, after which all five levels will be unlocked for players.
"The ubiquitous consumer adoption of Angry Birds and pistachios makes this partnership a natural fit," said Marc Seguin, senior director of marketing, North America for Wonderful Pistachios.
"We're excited to give consumers the snacks they crave with pistachios and feed the frenzy for new Angry Birds content with the launch of this game."
"We're delighted to be working with Wonderful Pistachios," added Peter Vesterbacka, Rovio's CMO. "We think our fans will get a kick out of cracking pistachios and playing their favourite game for the opportunity to win great prizes."
