Grand Theft Auto's Diamond Casino lets cash be turned into chips

So as I understand it, the game lets you spend real money to buy "chips" for gambling; but even if you win at the gambling, you can't get your money back out.

Sounds like a terrible deal. If I wanted to amuse myself by gambling with my hard-earned cash, I'd like there to be at least some chance of coming out ahead.

Great scheme for preying on naive teenagers, though.
