Payout Percentage (slots)

The primary measurement of a machine, calculated by the number of times a given set of symbols occurs in the computer selection table times its particular coin payout. All these payouts are added up and divided by the total possible combinations. The result is a percentage that, over the long run, the machine will return to the player. The range, practically, is 85 to 100 percent with few in the 97 to 100 category. This number is determined by the slot manager when ordering the machine, to provide the casino's mix of machines, and move his overall payout up or down.
