Yes, the trick with slot machines is knowing how to bet when you should, why? You cannot bet a very large balance in one spin, because obviously the balance would go away in the blink of an eye, bets on slot machines have to be very measured and have conditions of enjoyment and not regretting what is You are destined to lose, many players who enter a casino are thinking about how much they will win, and what they have to think about is how much they will lose, that way the system will not surprise them and it will make the player mature much faster and have more expertise in slots.
But surely there's no trick on that. There's no way to know when and how you should bet with. If there would be a pattern to recognize, someone would have already abused it to the point that slot devs would need to change the pattern radically. And i often bet large amounts with just one spin. I can either win big or small or lose everything. With enough spins i am only using more time to that result.
Major difference on these tactics are the fact that with other i can spend more time on slots, which can be fun too.
But what I know is that there are no patterns and tactics in slot games and we only need to press the bet button to wait for the reels to stop.
If we are lucky we will get a win and if not we will lose faster if we can't manage our balance.
So in slot games there is only balance management to last longer in the game until waiting for luck to come.
