For me, it is not a game marble, you can also make out cutting lines

I will meet Roberto half-way here. 
Master "game marbles" are a hard find but they most certainly exist.
When you take any game marble and light it up and enlarge it, you may get the same results.
I have experience doing this with a light box.(yep, I used to be quite mental about marbles).
I have no problem calling this one a Master Made “game marble”.
Nice work! Nice find!
It is a pretty marble, orange is pretty rare in any machine made marble.
Marble—On!!

Not related to ID'ing the marble in this post but game marbles do have patterns, etc., like akroorka said. Here is a picture of some game marbles from a Vitro Chinese Checker Box.
