51.com (formerly known as 51.com Inc.) is a Chinese online entertainment company primarily focused on online games. While their website currently presents a diverse range of services, including online games, dating, and other entertainment options, the historical emphasis and significant portion of their business remains centered around online gaming. The precise breakdown of revenue streams across different sectors isn't publicly readily available through their current website presentation.

The company’s online game offerings likely cater to the significant Chinese online gaming market. The types of games offered are not explicitly detailed on the current iteration of their website; a more detailed understanding would require access to archived information or past press releases. However, given the competitive landscape of the Chinese online gaming industry, it's reasonable to assume a variety of genres are represented, potentially including massively multiplayer online role-playing games (MMORPGs), mobile games, and potentially others.
