If a bank slot machines has signage that says “97.4% Return” what does that mean?
That means that every slot machine in that bank must be set to a theoretical return of at least 97.4%. In other words the longer your played the closer the ratio of wins to money bet would get to 97.4%. Slot machines are very volatile so in the short run anything can happen. Popular opinion has it that only one machine must be set to 97.4%, or that the overall average must be 97.4%. However I am taking a firm stand that both notions are wrong. My source is an agent, whom I won’t name, with the Nevada Gaming Control Board.
