On some sites you will get an award even if the bug is minor, let alone critical. but on some casino sites. like cheap casino websites or just starting out with small capital they think they won't pay you even if it's a critical bug unless you are a kind person who wants to volunteer something like that. If the bug comes from a large casino website with many communities, they will definitely pay you no matter how small the bug you get, you will be greatly appreciated. about how. I believe it is more effective to send them the email that is listed on their website.
Well, the actually truth of the matter is that, even some big gambling casinos are way more stingy than a start up, so, it still not every casino, whether big or small, that will be ready to pay for a bug that is minor, most won't actually, so what I think is, if the bug is minor, simply just point their eyes to it to get them notified, but don't expect any form of appreciation or reward.
But if it's a critical bug, like one that would allow hackers or even users use that bug as a means to steal from the casino real big, then some bug casinos definitely will reward a person for discovering such bug and not exploiting it, and some small casinos will also reward the person too based on their financial capacity.
But like I said before there are still some really big casinos that won't give a damn, what they did do is go behind you and fix the bug, and come back to tell you there was never a bug like that.
