  1. Every machine is designed to achieve a particular payback percentage - the percentage of money put in that is paid out to gamblers. Most jurisdictions require payback percentages to be above 75 percent, but they are usually closer to 90 to 97 percent. Your chances of winning are the same every time you play because the numbers the computer selects are always random. You don't have a better chance of winning the longer you stay at a particular machine. And on a typical machine, the losing images just above and below the jackpot image appear more often than the other images do; this gives the gambler the impression that he just missed the jackpot, which makes him want to keep gambling.
