Casual games company King revealed the Candy Crush Saga game has achieved more than half a billion installs across Facebook and mobile gadgets. King also said the addictive game has been played more than 150 billion times to date. The company has been reported to be an inital product offering (IPO) candidate in the US, according to a report published by TechCrunch.

The company is celebrating Candy Crush's first year anniversary today. The game was first released to Facebook users back in April 2012. It became a hit within that year after being released as a smartphone app. In February, King reported 9 billion monthly gameplays across all its games. These include Pet Rescue and Bubble Witch Saga, the report said.

The British game maker was recently reported to have confidentially filed for an IPO in the US. King reportedly used a secretive IPO registration process that was made possible by the Jumpstart Our Business Startups (JOBS) Act, TechCrunch reported.

According to The Wall Street Journal, King had hired Bank of America Corp, J.P. Morgan Chase & Co., and Credit Suisse Group AG to handle the IPO. Bloomberg said an IPO could value the company at USD5 billion to USD7 billion, the report stated.
