Martingale technique is not effective to use unless you bring large capital to continue to be doubled in every dice game, I will also change the game pattern to default mode to avoid high losses because dice games are unpredictable and only depend on luck factor without any guarantee technique used for winning predictions.
Even though you have large capital, it doesn't have any guarantee if the martingale technique will always work! actually you're doesn't need large capital to do that, just play with smallest bet. First you said martingale technique is only effective if you have large capital, but in the end you're said there's no technique to win in dice game, you're contradict yourself.
