Maybe we can do it this way if we have more capital during the game, or are still in the same room. If we have left the room, we will return to basics, or the same as when we just started the game.
In general, 10 minutes at the start of the game we will win, so we can make a bet with a larger amount, or adjust it so that there are enough rounds.
If we have been playing for a few minutes, but there are no signs of winning, then we leave to get another room game, but if there has been no change, it is better to leave the game until a few hours later. These are the ways that I often do in continuous betting.
I've heard of this strategy from gamblers in slot games but unfortunately the technique is not guaranteed to work to determine high wins, anyone who plays in the new room without winning for 5 minutes will be replaced by another room, but it's better to try your luck on one room for the opportunity to get a high chance of winning.
I don't know how it used to be in the past, maybe like you said and that's why we have those legends running around till this day, but today all spins on slots are independent, and, of course, you can do whatever you like if it makes your gambling experience better, but your actions will not affect the outcome.
