What's the rules on gambling-apps at the Market? Can one release applications that has a "bank system" that allows people to deposit money, play for money and win money through Google Market? Have anyone done it?
If one could, I'd guess large betting sites like Betfair and Unibet would have implemented such type of apps by now. I searched and found none, so that leads me to believe it's not allowed (I'm to lazy to dig into the submission guidelines right now).
That said (and now I'm taking on my consumer hat), which of the large betting/poker sites do have good apps for Android right now?
