A. As used in this section, unless the context requires a different meaning:
1. "Card position" means the first card
dealt, second card dealt in sequential order.
2. "Number position" means the first number
drawn in sequential order.
B. A network bingo system shall utilize randomizing procedures in the creation of network bingo cards.
C. Any random number generation, shuffling, or randomization of network bingo cards used in connection with a network bingo system must be by use of a random number generation application that has successfully passed standard tests for randomness and unpredictability including:
1. Each card position or number
position satisfies the 99% confidence limit using the standard chi-squared
analysis. "Chi-squared analysis" is the sum of the ratio of the square
difference between the expected result and the observed result to the expected
result.
2. Each card position or
number position does not produce a significant statistic with regard to
producing patterns of occurrences. Each card position or number position will
be considered random if it meets the 99% confidence level with regard to the
"run test" or any similar pattern testing statistic. The "run test" is a
mathematical statistic that determines the existence of recurring patterns
within a set of data.
3. Each card
position or number position is independently chosen without regard to any other
card or number drawn within that game play. This test is the "correlation
test." Each pair of card positions or number positions is considered random if
it meets the 99% confidence level using standard correlation
analysis.
4. Each card position or
number position is independently chosen without reference to the same card
position or number position in the previous game. This test is the "serial
correlation test." Each card position or number position is considered random
if it meets the 99% confidence level using standard serial correlation
analysis.
