Candy Crush Saga, the game that has become synonymous with addictive freemium gameplay, has turned a year old. And in celebration of the milestone developer King announced some interesting internal numbers that show roughly how many people have become slaves to candy making, and what the impact has been like across Facebook and mobile. Here are the big sticking points: Candy Crush Saga has been downloaded half a billion times across both Facebook and mobile. To put that in perspective, it took Angry Birds three years to reach the mind-boggling billion-download mark. Candy Crush has become super popular super fast. One in every 23 Facebook users worldwide is now a fan of Candy Crush Saga – a total of 51 million fans. All in all, more than 150 billion individual games have been played to date.
