Lets get things straight, as long as they are simple.
Phyngster is absolutely right. You cannot claim a coupon and then withdraw without following the rules, because: if you had lost, you would have claimed the bonus - naturally.
I had my trouble with inetbet once (their birthday promo) but after all: They are one of the very few absolutely trustworthy
RTG places.
Of course: winning has to to quite a lot with luck.
I had phantastic winning streaks , so that i thought, the software was not random, and i had my losing streaks, so that i was nearly certain, the software was "cheating".
Nonsense!
If you like
RTG, play there, or at Club world.
Or at a casino, which doesnt exist yet, maybe one, which is run by Grandacesgeisha. (got me?)
