The latest US IPO filing setting the financial media abuzz is King Digital, known for their super addictive Candy Crush Saga mobile game

The latest US IPO filing setting the financial media abuzz is King Digital, known for their super addictive Candy Crush Saga mobile game. It's no wonder King is planning on going public, in 2013 the company's revenues soared to $1.88 billion from $164 billion in the year prior. Like fellow game maker Zynga (ZNGA), management is attempting to strike while the iron is hot. Net profit in 2013 was $568 million on the strength of Candy Crush - which is being played by a whopping 93 million people a day. King's $500 million IPO should value the company at $8 billion to $10 billion. The question is, can King succeed where Zynga has failed miserably? The company will need to show sustained growth as well as diversification beyond its one big hit, ideally prior to the IPO.
