You should never play casino games with an expectation going in that you will come out with your money. The house has an edge. So just try and get some enjoyment out of playing and if you don't get any then don't play them.
If avoiding those games was that easy for the OP he would not be wasting that much amount gambling, he might be getting a rush wagging that much money in those casino and he might not be caring much about winning big amounts, not sure why the OP has not tried any other reputed casino in the market and try his luck elsewhere rather than loosing this much coins in a single casino
