Candy Crush maker King bought by Activision Blizzard

Candy Crush describes itself as the "sweetest game around" - but even so there's no guarantee that the $5.9bn (£3.8bn) takeover of King.com won't leave both investors and players with a bitter taste.

Candy Crush Saga, which was first launched on Facebook and smartphones in 2012, caught the public imagination and still makes up about a third of the company's revenue.

Even though the company has produced more than 200 games, including the popular Bubble Witch and Farm Heroes, it has yet to repeat the success it found with Candy Crush Saga.
