I'm afraid there's actually none at all. I used to devise a lot of strategies in dice before. One day one strategy may seem more effective than the other but the next day things would be the opposite. So I guess it still all boils down to luck.
The most famous classic Martingale is a generic gambling strategy which I still use from time to time. But I am not relying on it based on how effective it is. I simply use it to try to recover earlier losses as fast as I possibly could. But I'm not saying it is a strategy one should adopt.
Indeed, there is no single strategy in gambling that can provide long-term profits. Because most gambling games are based on luck, it is not
recommended to make gambling as a source of income. Regarding the martingale strategy, this is a common strategy used by many gamblers,
I have used it several times. But the martingale strategy if used in the long term is also not effective, because of the risk that we can lose all
the money we have. My advice is not to be confused about what strategy is profitable when playing gambling, in the end it will only make us stressed.
Playing gambling is only for entertainment, so just enjoy the process, let each of us luck determine our victory.
