Do you have favorite gaming strategies? Are there any effective approaches you know of that can be used in different games?
Luck based games doesn't entails strategy at all, obviously, it's either you are a lucky or not simply as that. In some card games let's say baccarat, other uses martingale system, but it's a disaster if you experience successive loses and you need to have a deep and bigger capital just to break even.
And with that, I doubt that you will have effective strategies, sooner or later the house edge are going to catch up with you. But if you ever found one and you win money, then it's better to quit early.
That true casino games are almost entirely games of luck where every success is not influenced by strategy but by the fate of each gambler, strategy is only limited to increasing the chances of winning and will not guarantee anything.
Regarding martingale, it can actually give win to every gambler who applies it, but it does require lot of money and even if experience consecutive losses while still have money, can still get win.
It just that winnings may never be comparable to what was previously lost in the application of martingale during gambling.
There will never be any method that can result in winnings, but there are several ways to avoid periodic losses, every winning must be withdrawn with the aim of returning the capital that has been deposited.
