There are some people doing some ritual before playing slot games like the pattern to play or pull the lever at the same time so there's a higher chance get a higher roll well it is just their beliefs we have a different perspective with it, when i play i always do is to spin 2 times and then make another automatically spin so i feel there's a piece of luck with that pattern well it is a slot game it is all about the algorithm of the programmed system.
I read about funny experiments where experimenters "trained" rats to do absurd things to get a piece of food. The human brain works on the same algorithms as the rat. If event A happened after we performed action B, then we are looking for a relationship between A and B, even if it is completely absent. If we logically see that this connection does not exist, then we take it for "magic" and instead of a conscious action A, we do a "ritual" A to get B. In fact, this is self-deception and does not work.
