Chillingo has forged itself one of the App Store's top positions thanks to its range of premier games such as Zen Bound and iDracula.

It's now branching out into other App Store genres with the expansion of its secondary publishing arm, Clickgamer.

"The Clickgamer brand is fully focused on casual iPhone games, entertainment and lifestyle applications - whereas Chillingo will be focused on AAA games with deeper gameplay and that essential wow-factor," Chillingo's director and co-founder Joe Wee tells PocketGamer.Biz.

The multi-platform publisher is already used to promote titles on various platforms including Windows Mobile, Symbian, BlackBerry and J2ME, and will now be used to publish casual games and software applications for the iPhone's App Store.

Clickgamer has already got to work on the iPhone with casual games Tankz and Dragon Panic, along with the complete iPhone catalogue of applications from PPCLink Mobile Software.
