Hi acorn... I ran into the same problem and have figured it out. Although there are links to the casino listed here on LCB
they are not the right links to use for the free chips from these new casinos
popping up. I made the mistake with onbling and just today got an email from onbling with the correct link for that affiliate.
I got an email from Lucky Club
from the affiliate and from that link I had no problem. I won't mention the affiliate here, but can say wait for the email in each case and use the link provided there only. Or wait for LCB to get a deal with the new casinos and then use the link provided by LCB. Unfortunately, the links being posted here are just not the ones with the attached bonus.
I will say I am not sure about these casinos... I got the bonus at lucky club but after playing forever it still says I have over $2600 WR... which is astronomical
for a $25 chip... even if I had not played all that I had before checking the last time. And there is no page there saying how much I aalready played, etc. be cautious.
(Mods, not sure this question and answer are in the right thread so please move at will.)
