According to the Wizard, betting on multiple lines has no effect on the pay out or the edge. I have watched some YouTube videos of Natasha Dow Schull talking about her book Addiction by Design and she claims that the purpose of lines is to "smooth" the gaming experience of slots. I am curious to learn if anyone has calculated this effect.
As you increase the number of lines from 1 to 50, how does this effect the standard deviation?
It helps you get to the long run quicker.
