I wonder how it's possible to set my website as infobox on google results?Do I need special meta tags, special structured data?For example, this website:It actually doesn't hold no special meta or anything, it's not in first results, but still it appears there, how is it possible?

Structured data. This tool will show you how to add it to your pages.You can use Google structured data testing tool to check your pages. The whole vocabulary is available on schema.org: schema for games is at schema.org/Game. The examples at the bottom of the schema pages have been helpful to me.
