I did not try any; but, it was very nice of you to offer!!

Not it, but I'll give you another hint for SpaceChem:

"It's the name of the train that takes four minutes to reach the gate to the Ninth Underworld".

bump!

I tried the Space Chem code and it told me that it is invalid.
Mystery solved, I guess. :-)

Hmm that's weird because spacechem was giveaway with gun monkeys by PC GAMER in the same event.
I'll check if was the right key, thanks
I found another! Dino D-Day.. I am going to update the first post with the key

Yes, Dino D-Day worked. Thank you!!

...
Or maybe I was just too stupid to realise that these are Steam codes?
...
Edit: Tried it on Steam now, says code has already been used.

Sorry I thought that I said it but seems that I forget. Thanks for tell me that was used. It could be a ninja? and thanks for warning me about the Steam advise. I must edit the post.

A google trivia!

How many goals (?) receive in the last (#) matchs ???

I don't know if the trivia is hard, nobody wants the game or somebody took it. Maybe the three ^^

Oops I see that I was excited about the Racing's Club victory so I didn't think clearly about another important clue for the pseudo-trivia how determinate the number of match! well the lasts matchs were wins in a row.. Six for be exactly. Anyway sorry for the late and my awkwardness

Now everybody can try it.
