Google has again made an attempt to challenge world’s leading social networking website Facebook with an altogether new platform, Google+.

On Tuesday Google released Google+ Project with four separate features, its biggest bet so far, The BBC reports.

The four features or areas are called circles, sparks, hangouts and huddle. Circles allows users to share their information and updates with a selected group. Sparks is a feature that will enable users to connect with fellows having common interests. Huddle is for Instant Messaging among a group and Hangout allows video conferencing among multiple users.

“Today, the connections between people increasingly happen online. Yet subtlety and substance of real-world interactions are lost in the rigidness of our online tools. In this basic online sharing is awkward. Even broken. And we aim to fix it,” said senior vice president for Engineering at Google Vic Gundotra in a company’s blog post.

The search engine giant has opened the service to a select group of Google users for field testing. The users will soon be allowed to invite others to join the platform.

Critics believe that the company has merely lifted features from Facebook to build its own kingdom with video conferencing as an add-on feature.
