Mobile users fuel King.com - Telegraph The company, often hailed as Britain's equivalent of Farmville creator Zynga, had not released figures for mobile usage since it developed its first mobile games less than a year ago. However, the company, which is understood to be gearing up for an initial public offering, said it has seen a huge surge in smartphone users following the release of a mobile version of Bubble Witch Saga last July. The game was tailored so that it could be easily played on Apple's iPhone devices. King's Candy Crush Saga game has also been hugely popular amongst mobile users, topping the charts as the most popular Facebook game by any producer. The growth in mobile usage has helped King to attract 108m unique players a month, who play King.com games more than 12bn times a month between them.
