I've never said that forever because forever is a long time but everyone should take a break for even a few days because it clears the head and settles your emotional response improving your chances to win which is what you what ultimately.
Lately I have come to another sort of "conclusion" I would say. I have been playing the Gates of Olympus Super Scatter and I have been observing some sort of pattern, I guess everyone know though I need to reiterate it here. Whenever I have played with a low budget I have had more losing sessions without once being able to get above my initial balance while when I have used a high balance of 250 dollars or more have managed to win, I use IDR in both cases as a currency. This is to show that the more money you have the better your chances are, this to tell everyone that the more days you cool off the more money and chances you will have when you come back.
