Hi,
seems BB1Web does really know what he's doing and saying; and the conclusion I've come to is that it is better to promote a few really good casinos rather than hundreds, including all the 'possible' bad apples out there.
You have to read the T&C's before signing up for any bonus; if you don't then its your own fault that you get caught dissatisfied and disgruntled.
BTW, a lot of the RTG casinos do the 20x, 30x and 'so many times' play through thing; if you don't know what you're doing or signing up for then stay far away; a lot of them (RTG) also do promote a 'no play through requirement' but beware of the 'bonus is no-cashable' parts; also, check out the casinos giving cash back rewards which I initially thought was a loyalty bonus but it isn't; it's really cash back on your LOSSES.
Good luck next time.
