King.com and other Play for Cash sites. Are they for real and worth the trouble?

Question

What is the catch with these sites? Can you make any money on it, assuming of course that you win more than you lose :)

Answer 1

I bet that they do give you money, you just have to be really good at the game.

Answer 2

too much comission to the site on these type of games.  You would have to be very dominant, better to try moola where the betting is free, and no commision.  I f you are good you can make large bets without ever depositing money.

I am a pro gambler, though primarily sports, that is something that is much more realistic to make some real money.
