TOKYO -- It only took Pokemon Go about three months to capture $600 million from users.
According to U.S. startup Niantic, which manages the app, Pokemon Go a month or so ago had been downloaded more than 500 million times around the world.
It debuted in July.
Although the game can be played for free, some players buy virtual items that can help them advance.
Pokemon Go breached the $600 million mark 2.5 times faster than Candy Crush Saga, a smash hit that came out in the spring of 2012, and more than five times faster than Puzzle & Dragons, another much-loved game that came out in early 2012, according to App Annie, a U.S. analyst that studies apps and virtual goods.
Friday marked the 100th day since Pokemon Go became available in Japan. According to a survey by Tokyo-based research firm MMD Labo, more than 60% of people who downloaded and played Pokemon Go were still using the app three weeks after the game's Japan release.
The norm is for 80% to 90% of a new smartphone game's Japan users to stop playing two weeks after its release.
Pokemon Co., a Nintendo affiliate based in Tokyo, was involved in the game's development.
Licensing fees paid to Pokemon Co. will be reflected in Nintendo's earnings according to the number of shares Nintendo holds in Pokemon Co.
Nintendo has apparently added about 10 billion yen ($95.4 million) in profit for the July-September period.
