redsales: Your link and alanback's say exactly what I was saying! Both links do not mention how the percentage of payoff is figured or changed. I used 7760 coins out of 8000 positions as an example of 97%. To change it to say 95% you'd have to lower the total payout to 7600. This could as easy as changing a two cherry payout from 6 coins to 5 if there was 160 ways of getting two cherries. This would make the machine "tighter". It has nothing to do with random numbers, electric motors, or mechanical drives.

And the whole thing works on the long run of the game, not your particular visit. If you're going to win, then you need to get lucky. It's that simple. As for increasing your chance of winning on a slot machine, understanding the casino's marketing tactics and how they use human nature to their advantage is how you do it. As the one link shows some of their tactics by positioning the looser machine where they'll be seen by people waiting line. What it says about machines next to a buffet line being tighter makes sense too. The loose ones should be three rows away so that the people in line will see people winning and will try the ones next to the line because they don't want to lose their spot in line.
