cuz its 'easy & quick money' where you will nowhere else make such quick legitimately
There is not such a thing as easy and quick money, you need to work hard for it, even those few gamblers that are able to get some profits out of the casino games make great effort to reach such results.
The strategy of all casinos and gambling games to let you win in the beginning. You are going crazy from all that winnings and fast & quick money. That easy make you involved. You start to believe in your luck and think that you have some special skills. But all this is scam. Then you loose over and over again with trying to bring back your luck.
Casinos don't need to fix the games the casino games already offer and advantage to the casino known as the house edge so there is no need to do that, because if a casino was caught cheating their customers, they will stop playing at that casino and the casino will probably go bankrupt.
