I can't confirm this, so you must had really very much of pain
As an example, yesterday i made on inetbet a deposit with $ 200.- and after a half hour i cashed out exactly $ 464.-, so i think that's okay
Then another example by 49er Casino, i deposited only $ 20.-, so i could only make a total bet of 20.- Cent, but there i get on Cleopatra's Gold "5 Pyramides" and that was $ 100.-
Okay i'm happy about that, but if i had made a bet of $ 2.- this could be a $ 1.000.- win!
So it looks like, that you have really a very long painful way, but maybe you chooesd the false casino, with lower payouts?
I've also seen, that sometimes there are comming bonus rounds after bonus rounds and it looks very good for me, but then you can play 1 hour and there comes no bonus round again (i lost then $ 100.- in a total 20.- cent bet, that's are $ 1.000.- in a $ 2.- Bet!), so if you have the pain and play exactly in this phase, you can't win anything

But after this loosing phase comes another big wins and bonus rounds, but certainley you should have enough money to play, or play only in 20.- Cent Bets, or you have the big risk to loose all your money, but you can certainley also win something

These are the game rules
