After becoming the most popular game in the world ever, every new Angry Birds game quickly attracts a huge following.

But the title, which has sold more than 350million copies, has an unlikely spin-off - a theme-park edition.

The unlicensed attraction - dubbed the first 3D Angry Birds game - has been launched at a park in China.

New game: One of the Angry Birds is fired at the pig in a castle at the Chinese theme park

Players use a slingshot to fire the birds and knock down pigs which are perched on a castle.

The game, at a park in the Hunan Province, is part of a month-long stress reduction festival and opened on September 1.

There have long been rumours that Rovio, the game's Finnish manufacturers, will licence a high-budget Angry Birds theme park.

Targets: The pigs that competitors have to aim for are perched in these castle-like structures

A spokesman for the park told Gamersky.com: 'This (Angry Birds attraction) serves as a method for people to purge themselves and to gain happiness.'

The attraction is the latest example of China infringing western copyrights.

A fake Apple store which looked exactly like a genuine outlet was shut down in Kunming City in July after it was exposed as a fake.
