After its last month launch of a widget that enabled web sites to embed some casual games on their sites, Heyzap has now announced a launch of a game database that can be categorized into segments like sports or puzzles.

With over 3,000 sites already having installed Heyzap’s widget, and gamers having played nearly 5 million minutes during the one-month post-launch period, the further organization of games into categories will help game-developers effortlessly pick contextualized casual games content.

The San Francisco-based Heyzap said that the game-grouping would result in something similar to a YouTube of Flash games; and with the use of the API, 6,000 Flash-based casual games would be accessed by the developers.

In partnership with Cooliris and Weebly, Heyzap also plans to launch an applications programming interface, whereby developers would be able to create their own game portals and supplement certain games. Such a launch will enable publishers to directly upload their games on the site, thereby reaching out to a much larger audience than what they might reach otherwise.

Presently funded by Y Combinator, Heyzap would look for more funds once things start rolling as expected. There is, however, there is already stiff competition that Heyzap faces in the web-gaming arena – what with names like Kongregate, Oberon Media, Wild Tangent, Games2Win, Addicting Games, and GameCurry!
