Not a html wiz myself, just assuming from common sense. You have to put the information somewhere with surveys/similar: either as cookie or html link, possibly with a few more methods available. As any type of website & game will have unique user-ids these are usually taken for this.

What device was used, what OS that device had - both probably to display everything correctly for those devices/OSs (in above url a platform iOS & iPhone 7.04, model iPod touch 5,1 are noted).

Not sure about "dixe" and "nixe" but there is clearly: user_id (from game i assume), openudid (uniqueidentifier used by advertisers, it's an API by the same name) & advertising id (to show regional ads).

Actually cracked it down quite a bit now. ;)
