That's how long the war has raged between Rovio's egg-pinching pigs and angered birds. Since then, there's been an Star Wars partnership, a TV series, books and an army of plush toys. There's even a feature length film due May 2016.
But the next major instalment in one of the biggest video game titles of all time (42 million downloads and counting) has arrived on smartphones in the form of Angry Birds 2.
In anticipation of Rovio's sequel filling your empty hours (or stealing the full ones), we've picked the brains of the app-obsessed Google Play team to provide a list of the most addictive arcade and action titles available for your thumbs. Prepare for some serious procrastination.
Angry Birds 2
They're back, with some new feathered tricks. All the standard mechanics return, but now you're able to pick which bird you fire next, adding a new level of strategy to the game. There are bigger levels, new multiplayer challenges and many, many more excuses to stay up late for "just one more try".
Mars Pop - Bubble Shooter
You'e right, there's nothing alluring about that title. But behind the bubblegum façade lies a deeply addictive multiplayer experience. Similar to oh-so-many colour-matching shooters, this app allows you to take part in international tournaments and challenge friends.
Marvel Contest of Champions
Admit it. The notion of a beat'em'up game that pits Wolverine against Iron Man, has just raised your heart rate a touch. A furious, fast screen tapper, you're able to pit all your favourite Marvel characters against all your slightly less favoured Marvel characters. Your phone's battery won't know what hit it.
If you don't love arcade sniper games, you're wrong. Just wrong.
Playing Agent 47, you pick off your foes from range through a variety of levels and challenges. Points are awarded for trickier shots - there's a neat trick you can do with a glass barrier we don't want to spoil for you.
Batman Arkham Origins
Marvel on Marvel not your thing? Then this Batman battler should be more your thing. Taking the combat element from the hugely popular console series, this app manages to capture the slick combo skills of the main game. And using a Batarang is as cool as you hope it would be.
Daddy Long Legs
"Walk as far as you can" doesn't sound like much of a game - but you're going to want to try this bizarre take on arcade gaming. You have to time the leg movements of your 'Daddy', which will collapse in hilarious style should you move too quickly or slowly. A weird and wonderful game.
