Im writing a review site where the community rates posts. I have noticed that Google can pick up on this ratings and display them in its search results. Does anyone know how this is achieved?
An example is a review site like IGN, where in their screen shot below they have indicated their review has a rating of 9.3/10.

How can I indicate to Google my own review rating? Maybe some sort of custom meta tag or something.
