I used to play dice in online casinos and apply the martingale technique. In the beginning, I had some profit but as the time went by I started losing and losing and I wasn't able to cover my initial bet.
Now I am trying something like the same but differently. I pick a big football club and I bet that it will lose. If I lose my bet, I double it and so on.
There is no working strategy even different style like Martingale doesn't seems to work most of the times in dice. If you want to win, try different strategies and do not stick in only one strat because the system may read your betting style. If you want to win fast, try to bet all in. Lol but the moment you increase your bet especially when you all in, more chance that you will gonna lose than you win.
