I think casinos have the right to allow, or reject, withdraw from Faucet.
Of course they do, but then it should be clearly defined in ther ToS.
Then again, how do you explain this kind of promotion?
Well, First Of all they don’t have Jackpot System.
2nd, It's Common sense that you have to pay to buy products. In Their case, They did some mistakes, But As I can see, They Updated Their TOS.
3rd. Every Company Has their Our Slogan And Taglines. (Take the Bonus and Wins) It's not mean You can do whatever you want with bonus. As Cratoon Said, This guy continuously Claimed Faucet till he manage some big amount. He claimed faucet every day and tried to make something, but he failed. And luckily he he managed that amount with his last claim without risking a Penny.
I have another financial project, So I understand Their Pain.
