Candy Crush Saga, the matching game played by millions on their commute, has reached $20 billion in revenue since its 2012 launch, maker King Tjodolf Sommestad said Tuesday.
He added that it would soon release levels up to 15,000 for the most dedicated players.
The game first appeared on the web before transitioning to Facebook and then mobile phones, significantly expanding its user base. It has been downloaded a staggering five billion times to date.
Candy Crush pioneered the "freemium" model, where the game is free to play, but players can spend money to enhance their performance or opt to watch advertisements for power-ups.
Sommestad stated that Candy Crush and its sibling titles like Farm Heroes Saga have demonstrated that mobile games can maintain enduring appeal.
“We’ve proven to ourselves and to the industry that it is possible to reignite games that are years old and keep them relevant for a decade or longer, and break records even a decade in,” Sommestad said in an interview.
King has been owned by the American company Activision Blizzard since 2016, known for games like Call of Duty, and it recently approved Microsoft's acquisition of the company for $69 billion. King contributed around $747 million to Activision's net revenue in the second quarter, accounting for a 31% increase.
