The redundancies, which will account for 16 per cent of the firm's workforce, were announced online by the company's chief executive Mikael Hed.

"We have been building our team on assumptions of faster growth than have materialised," he said.

As a result, the company will have to simplify its business structure, focusing on the three areas with the highest growth potential: games, media and consumer products.

While the firm has branches located in Sweden, Japan, China, South Korea and the UK, the cuts are only expected to affect its Finland offices.

According to Rovio, Angry Birds is the number one paid mobile application of all time. Since launching on iOS in 2009, the game has expanded into a fully-fledged brand, encompassing a TV series, toys and even an animated movie due to be released in 2016.

Despite the success of the video game franchise, Rovio announced net profits in 2013 that were less than half that of the previous year's figures.
