CoC related website - legal questions
Hi, I'm thinking about creating a website with CoC tips, tricks, strategies etc. Is it legal to register a domain with clash of clans in it (it would be something like clash-of-clans-tips.com but in Spanish) and is it all right to use screenshots and artwork from the game (for example walls set-ups using real walls from CoC) just for the purpose of explaining some techniques?
In the Supercell page they have some downloadable logos and banners, so I assume it would be no problem to use them, also YouTube is full of CoC recordings which after all use the game's artwork. But I would like to make it clear what is legal and what not in terms of legal use of the name and screenshots before proceeding any further with the idea.
Thank you in advance for your advice!
