Mo. Code Regs. tit. 11 § 45-5.193
Current through Register Vol. 49, No. 23, December 2, 2024
Section 11 CSR 45-5.193 - Statistical Performance of Electronic Gaming DevicesPURPOSE: This rule establishes the standards for electronic gaming device statistical performance.
(1) Gaming equipment suppliers shall- (A) Provide the volatility index (VI) on all Probability Accounting Report (PAR) sheets. The volatility index shall be calculated at ninety-five percent (95%) confidence level and at one (1)-line played, or the electronic gaming device (EGD) minimum bet where applicable. For EGDs with non-linear pay tables, the bet with the lowest payout shall be used. The calculations shall be accomplished by utilizing the below formulas: VI = k[Greek small letter sigma]
Where k; equals the z score for the required confidence level and [Greek small letter sigma] is the standard deviation for the game.
The standard deviation is calculated as follows:

Net Payi = (the amount of each individual pay divided by the number of coins wagered)
E. V. = the payback percentage for the game Probabilityi = probability of each Net Payi
(B) Calculate PAR sheets utilizing theoretical analysis where feasible. When the Return To Player (RTP) percentage cannot be feasibly computed using theoretical analysis the RTP percentage shall be computed such that the half-width of the ninety-five percent (95%) confidence interval is not more than .01%. Within these PAR sheets, provide standard confidence intervals at a confidence level of ninety-five percent (95%) with each interval showing 10,000, 100,000, 1,000,000, 10,000,000, and 100,000,000 games played;(C) Obtain written authorization from the commission prior to submitting any EGDs that support features which introduce independent VIs, separate from the base game VI, to an independent testing laboratory;(D) All EGD software submitted for approval after January 1, 2014, shall ensure each EGD payout that is calculated into the PAR sheet's RTP for the game increments the appropriate coin-out, attendant-paid jackpot, attendant-paid progressive payout, or machine-paid progressive payout meter to allow for the analysis of game performance. Any features not calculated into the PAR sheet's RTP of the game shall not increment these meters; and(E) Ensure all base game, bonus and progressive winnings from a wager are aggregated to determine whether the EGD payout is a reportable and/or taxable event requiring the EGD to lock up allowing for the preparation of a W-2G and state withholdings as required by section 313.826, RSMo.(2) Independent testing laboratories shall- (A) Independently verify the manufacturers' VI and RTP percentage, then detail the findings in the certification letter; and(B) Provide standard confidence intervals at a confidence level of ninety-nine percent (99%) in the certification letters using this formula- Click to view image
with the number of games played for each interval being 10,000, 100,000, 1,000,000, 10,000,000, and 100,000,000.
