Title 13 - Gaming
Part 8 - TECHNICAL STANDARDS FOR GAMING DEVICES AND ON-LINE SLOT SYSTEMS
Chapter 3 - PROPER ACCOUNTING FOR GAMING DEVICES
Rule 13-8-3.1 - Changes to payout percentage

(a). The theoretical payback percentage of a gaming device must not be capable of being changed without making a hardware or software change in the device. For purposes of this standard, the addition of an attendant paid bonus, a progressive jackpot, or a change in rate of progression of an existing progressive jackpot is not considered to be a change in the theoretical payback of the gaming device.

(b). Notwithstanding subsection (1), draw poker type gaming devices may have switch selectable or menu selectable top award values so long as the selectable range does not alter the payback percentage of the device by more than 1 percent with typical field play.

(c). For those gaming devices which are already approved as of the effective date of this regulation, this subsection (3) shall apply for a period of one year after the effective date of this regulation. Gaming devices which are considered to be slot machines and which have a difference in theoretical payback percentage which exceeds 4 percent for a single-coin play versus maximum-bet play, must have electronically stored digital meters of at least 6 digits which record the number of plays made in each category of wager for which the theoretical payback percentage is different from the single-coin bet category.
