Please explain Intercasino / Interpoker bonuses for an idiot

[Theodore Donald Kiravatsos]

So I'm pretty confused after reading posts from month to month...

1) They give you $100 free every month? Do you have to deposit to get this, or does it just show up somewhere?

2) It is given in either poker or the casino? I understand there is a 25x WR for BJ, what is the raked hand requirement for poker?

I guess I'm just totally confused by Intercasino and would like to know the nuts and bolts of their monthly promotions.

3) Do they give you a hassle for using Neteller?
