Once Nokia finally manages to get players to its new N-Gage mobile game service, it apparently wants to make sure they have no reason to go anywhere else. The mobile phone giant has come out with a tool that lets users upload content to create their own "mini games" and share them with others in the community, InformationWeek reports.

Gamers in the company's Yamake community can upload text, pictures, audio clips and video from their mobile device or PC and use the online tools to morph the content into various types of games, including picture puzzles and quiz games, the article says. The user-created games can then be shared between N-Gage-compatible phones and other S60-based devices via MMS.
