Some time ago I watched a documentary about gambling addicts. They claimed they were playing because the game puts you in a kind of stupor which is like being high. Winning money did not matter to them as long as the high held on. It is a bit counter intuitive but winning money is not the point of gambling. If an addict wins money he will imedialty spend that money to gamble more.

This app skips the winning and some degree spending, money part altogether. Which is smart if you want to exploit gambling addincts and avoid regulations.
