A slot machine is a gambling device that features many features, including different payback percentages. The payback percentage refers to the percentage of money that a player puts into a machine that is returned to the player. If a slot machine were to have a payout of 95%, for example, the casino would keep 10 percent of all money placed into it. In contrast, if the payout percentage were 90%, the casino would hand out all of the money. Changing a slot machine’s payback percentage is a time-consuming process, and in some jurisdictions, a physical swap of the EPROM is required. In New Jersey, this is required to be done in the presence of Gaming Control Board officials.
