We have a mobile-friendly version that shows when using your phone. This version is consistent across forums and will not show you the fancy designs for individual games. It is a simple text-based forum that's primary purpose is simple reading and posting on a mobile device.
If you want to see the full versions of the forums on your phone, simply go to the "Full Site" link at the bottom of any page. That will be the same experience as looking through a browser or on your computer. Tablets also use the "full site" versions.
If you want to return to the mobile version after seeing the "Full site" version, simply log out and log back in again; the default mobile-friendly version will now be visible.
