Angry Bird Playground

It started with an app game, followed by several merchandising products and it was even used as a design for a formal gown in a presidential gathering. Now, tThe world's most popular computer game will become live attractions for children next year when the first "Angry Birds" playgrounds appear in Finland.

The developer said last 12 December 2011 that two Finnish towns will get the first playgrounds kitted out with equipment inspired by the game's characters as it signed a global deal with playground equipment manufacturer Lappset.

"The playgrounds fit perfectly into the Angry Birds world and our way of thinking," Rovio marketing chief Peter Vesterbacka said in a statement.

The Angry Birds playground product range features animal spring riders, swings, sandpits and a range of climbing towers with slides, and a unique Angry Birds arcade game.

Mobile gaming firm Rovio, which plans to go public within a few years, said last month its hit game had reached a record 500 million downloads less than two years after its launch.

Unlike most mobile game crazes, Angry Birds, in which players use a slingshot to attack pigs who steal the birds' eggs, has stayed atop the charts since it was launched for Apple's iPhone in 2009.

Reuters reported that Rovio is expanding the brand across traditional merchandising, to the big screen with film studios.

Earlier this year, Rovio raised US$ 42 million from venture capital firms including Accel Partners, which previously backed Facebook and Baidu, and Skype founder Niklas Zennstroem's venture capital firm Atomico Ventures.

Rovio was founded in 2003 after three students including Niklas Hed — CEO Mikael Hed's cousin and now Rovio's COO — won a game-development competition sponsored by Finnish mobile phone maker Nokia Oyj and Hewlett-Packard CO.
