For example, I have not yet heard of any winning strategy for playing dice or slots.
I heard a strategy for playing games is patient, where most gamblers don't have.
It is not always possible to maintain patience when you lose and lose money over and over again. I know this very well because I have experienced it many times in practice. And this is despite the fact that I did not set a goal to earn money.
I feel your pain, the same endless loop has happened on my unlucky game sessions too. Patience is not required for the last dollar of bankroll, the game melts down the balance faster than blink of an eye if you have strong patience.
