King Digital Entertainment shares fell more than 15 percent in their market debut Wednesday, making it the worst-performing initial public offering so far this year.
King's "Candy Crush Saga" climbed atop download charts on Facebook and iPhone, but investors worried if the London-based game maker could produce another home run.
King's shares hit an intraday low of $18.25 on Thursday from their IPO price of $22.50, which valued the company at about $6 billion.
Here is a list of other IPO flops this year.
