Ive been into playing of dice game and tried martingale strategy it never worked for long. Actually it depends on your base bet, whatever strategy you have it will never worked good for long. Eventually you will lose the game and just waste of money.
Martingale never worked for me either. I'm tired of trying it again and again, the progress gave me an headache so I never tried to do it again. Those gamblers that are saying it is working to them and gave them good profit it's up to them or they are just lucky enough for trying. But for those people that wants to try out, try it and see for yourself.
If you want martingale to work for you, you must first find the minimum number of shots you have to give before winning any bet. Apparently, you don't have much luck in gambling; at least your words convey this message.
Once you calculated that number, divide your amount according to martingale method and then try it. It will work few times for sure. However, don't increase your betting amount in any case.
