Finland, 2009. Rovio’s finest creative minds are devising a new game. Something good; something that’ll help them hit the big time.

In the midst of the brainstorming session, designer Jaakko Iisalo steps forward with a character he’s been working on: a bright-red spherical bird who looks rather miffed. Everyone has a good laugh. Alright, they decide. Let’s go with this.

Nobody knew just how high that wingless bird would soar. Angry Birds has been downloaded more than 3 billion times, and enjoys a film-star level of global fame. Play the game for 30 seconds and you’ll know why. Angry Birds is undeniably fun.

Dastardly pigs have stolen the bird’s eggs. This flock can’t fly, but that doesn’t mean they’ll sit back and watch as their offspring become an omelette breakfast for luminous-green swine.

Load up the slingshot, pull it back at just the right angle, and unleash feathered hell, using each bird’s unique power to wreak havoc on a nearby pig fortress. Angry Birds has the timeless entertainment value of jumping up and down on a matchstick diorama built by someone you really, really dislike.

Angry Birds 2 takes the iconic series to tottering new heights, with boss battles, magic spells, customisable outfits and regular special events.

It’s swelling with fancy features, too – you can nurture the next generation of birds by adopting a hatchling. Level up the adorable little guy and you’ll earn Rainbow Feathers and stat boosts for your flock. Who says parenting isn’t rewarding?

Training pays off at the Mighty Eagle Shop, where you can spend coins earned in bootcamp on special items, including exclusive hats. And speaking of hats... Once a mere fashion statement, hats now come with upgrades: they’ll supercharge your flock power during a special event and remain extra-stylish forever afterwards.

There’s also a competitive arena with improved matchmaking and a Master League for top demolishers, so that you may distinguish yourself as the angriest of all the birds.

So, if you’re looking to blow off some steam the old-fashioned way, warm up your sling, practise your best beaky scowl and take aim – those pigs have rested for long enough.
