Candy Crush Saga generated an insane $1.5 billion in revenue last year

This is what the creator of Flappy Bird was potentially giving up when he took his game down from the App Store and Google Play. Candy Crush Saga publisher King filed IPO registration paperwork on Tuesday and revealed that it generated a whopping $1.88 billion in revenue in 2013 along with $1.98 billion in gross bookings, which the company defines as the “total amount paid by our users for virtual items and for access to skill tournaments.” While this in and of itself is impressive, here’s the truly crazy part: King says that 78% of its gross bookings came from Candy Crush Saga alone, which means that Candy Crush made around $1.54 billion in gross bookings last year. Of course, Candy Crush’s ridiculous strength could also be King’s greatest weakness: It has no other games that even come close to matching the user base of its flagship title and if user interest starts to die off, King could find itself in Zynga territory very quickly.
