The easiest strategy on gambling probably use martingale to playing dice because this is pretty easy to do so that everytime you lost then you can raise up the bets but unfortunately this is not long term strategy because i'm sure most of gamblers has been done use this atrategy and majority lost with deep pocket
yeh, martingale has been mentioned already. I really don't like calling it a *profitable* betting strategy cos you will always hit sportsbook/casino limits on the inevitable bad run... but we can put in for now.
