It's time for my first puzzle [Little Hint added]

I thought it would not be a bad idea to make a puzzle-giveaway. You do not have to say "hello" or "thank you" to me. It may sound a little bit French of me or even Italian but once you get the hang of it, it will flow like a river. Of course it may take some help from Google to find out, that there is a symbol for "Stickstoff", but surely all the Hawkeyes in this forum will find out, that "Stickstoff" is the German name for a chemical element which normally comes in a gaseous State. So without any further Abbreviations I give you the link, where you can enter the Solution for this puzzle:

Rules

1. Please don't post any clues or even solutions in this forum. Let it be up to me, to decide to give hints or not.
2. You find the solution in the text above. Get the clues together right and solve them and it shouldn't be a mistery to you.
3. If you need clues, write a comment. I may help you. (But I also may not :) ).
4. This one is open for every level
5. Be curious

EDIT: Forgot to tell here: The Giveaway (and therefore the puzzle) ends sunday in a week at 8 p.m. CET (thats 3 p.m. EDT)

Hint:
Since less than 2 days are left I give a little hint: Don't try to find the name of the game directly. Only if you solve the clues you find out the game. But then you do so directly.
