Earlier this week, casual gaming juggernaut Zynga received yet another outside investment of an undisclosed sum of money. A number of news outlets speculated on the aforementioned sum and what it's done to the company's bottom line -- for instance, the Wall Street Journal (via Develop) reported that the investment was worth $250 million, valuing the company at somewhere between $7 billion and $10 billion. All Things Digital says the investment was for $500 million, and claimed (alongside the New York Times) that the company is worth "nearly $10 billion."

Meanwhile, Joystiq.com's gaming industry luminaries have valued the new investment at "many, many millions," placing Zynga's net worth at "the largest number anyone's ever seen or written." Feel free to use those valuations as well, business guys.
