Of course, they won’t just give away the $10 bonus to anyone to try their casino. Even if OP didn’t mention it, I'm sure there are minimum requirements, like at least being Jr. Member or having Bitcointalk account that wasn't created just to claim the bonus. Like in your case, it's pretty obvious that you made that account just to get the $10 and try the casino.

There are even three newbies who want to avail the $10 I'm not sure how they even found out about this. lol For sure an alt account.
