You can try for yourself to know if that is works or not. But as far as I know, there is no 100% guaranteed method that will work many times in the gambling games because you need to find what method will work for you. You need to modify the method from time to time so that it could work, but still, it is difficult to get the right method. Maybe you can win for one or two or three times, but the next bet, I don't think you will win again. Besides using the right method, you need to have luck.
