How does rank system work? Why newbie (personally me), can be higher in rank than old player, who has invented much stronger armies and built more troops?

The rank is based on your score, which is dependent on your army size, population size, relics, conquers and crystals. Have more of these than said player, and you get a better rank. Be warned though, Rank does not mean immunity.

I'll become a prick But where I could find information about it? Cause I think, that someone knows it, and uses it... And newbies are left just to test it and suffer it...

tappa i really suggest you to go get a mentor your mentor can answer and show you a good way to play the game

It seems I need to pay someone (mentors) in order to play BD I was just expecting to find out, how the game works... And actually I've got no answer into 5 questions... No money - no honey...

No, mentors are free volunteers Tappa.

But why can't I get answers in forums then?

To be honest, the forums are a ghost town for most of the time, and some players want their trade secrets to stay as they are: secrets. Anyways, I've given you the link, and the site should answer what you need to know for the most part. If you need specifics, try clicking on the link on my signature at the bottom.

Thanks for your responses, but your tutorial link is not working...

Really? works fine for me. Anyways, try it now.
