I just tried playing dice last night and trying the martingale system. Boy, did it not work at all. It might work if I used a lot more money to start with, so I would've had more time to actually get some wins and rebound, but I clearly did not start enough. I might try again a little later.
Don't start again, finale of your effort will always be the same. That is because martingale is flawed by design.
But it is always a magnet for newcomers, I don't know why. You need to realize that you will be exposed to extremely high risk with little reward while using martingale.
This system was responsible for bankruptcy of many gamblers who didn't realize they suffered long losing streak.
If take a look at the law of statistics - there is less than 0.1% chance of losing a 50/50 bet more than 9 times in a row.
But unfortunately players who use martingale also often use auto bet function which allows for thousands of bets during a session.
So there is MORE than likely to see this outcome once and that that is basically game over for you...
