All the games are showing up in one long column on the left, with the 'category' links all the way at the bottom. Is it showing up like this for anyone else?

I'm using Firefox if that matters.

Yeah it's doing it for me too.

Try clearing your cache - the site's CSS has been updated. (Shift+F5 or Ctrl+F5 should do it).

Also make sure your browser window is wide enough! If you make it narrow it will use the phone layout.

Ctrl+F5 did the trick, thanks!
