SECTION 325:85-15-50. RNG requirements
Latest version.
- Where the authorized game or system uses a RNG to make selections, such RNG and the selections shall:(1) Be statistically independent.(2) Conform to the desired random distribution.(3) Pass various recognized statistical tests.(4) Be unpredictable.(5) Be cycled continuously in the background between games and during game play at a speed that cannot be timed by the player.(6) Randomly determine the first seed by an uncontrolled event. After every game, there shall be a random change in the RNG process (new seed, random timer, delay, etc.). This will verify the RNG does not start at the same value, every time. It is permissible not to use a random seed; however, the Manufacturer must ensure that the games will not synchronize.(7) If a random number with a range shorter than that provided by the RNG is required for some purpose within the Player Terminal, the method of re-scaling, (i.e., converting the number to the lower range) is to be designed in such a way that all numbers within the lower range are equally probable.(8) If a particular random number selected is outside the range of equal distribution of rescaling values, it is permissible to discard that random number and select the next in sequence for the purpose of re-scaling.(9) Unless otherwise denoted on the payglass, where the Player Terminal plays a game that is recognizable such as electronic card games, the same probabilities associated with the live game shall be evident in the simulated game. For example, the odds of drawing a specific card or cards in an electronic card game shall be the same in the live game as if a physical deck of cards were being used. Card games also must meet the following:(A) Cards once removed from the deck shall not be returned to the deck except as provided by the rules of the game depicted; and(B) As cards are removed from the deck, they shall be immediately used as directed by the rules of the game (i.e., the cards are not to be discarded due to adaptive behavior by the Player Terminal).(10) Mechanical-based RNG games are games that use the laws of physics to generate the outcome of the game. All mechanical-based RNG games must meet the requirements of these Rules with the exception of the requirement stated above that dictate the requirements for electronic RNGs.(11) Each possible permutation or combination of game elements that produces winning or losing game outcomes shall be available for random selection at the initiation of each play, unless otherwise denoted by the game.(12) A Player Terminal shall use appropriate communication protocols to protect the RNG and random selection process from influence by associated equipment, which may be communicating with the Player Terminal.
