Zynga CEO Mark Pincus speaks at a Zynga event Tuesday, Oct. 11, 2011, in San Francisco. Zynga is adding more ways for people to play its Web games as it grooms its business for an initial public offering of stock. The expansion announced Tuesday will enable Zynga's 232 million users worldwide to play games such as CityVille and Mafia Wars on the company's own website instead of only on Facebook and other social networking services.
