Random Number Generators
Random Number Generators (RNG's) are used in both Terrestrial and Interactive gaming systems to drive the game outcome determination process. Arguably the most critical aspect of gaming systems, RNG's pose the most significant concern for Manufacturers, Regulators and Operators alike. TST is renowned for its RNG testing. TST has performed numerous evaluations on both Software and Hardware RNG's. On more than one occasion, TST has found errors or omissions in RNG's previously tested by other testing agencies.
TST performs RNG evaluations with a special emphasis on the distribution and unpredictability of the RNG application. The RNG's randomness is inspected using both the raw output of the RNG, and how that raw output is scaled and mapped to particular application outcomes. This is important, as the way an RNG's output is scaled and mapped could potentially show bias towards certain outcomes.
TST's RNG evaluation approach has on more than one occasion, to identify errors or omissions in RNGs around the world. The RNG's randomness would be inspected using both the raw output of the RNG, and how that raw output is scaled and mapped to particular application outcomes. This is important, as the way an RNG's output is scaled and mapped could potentially show bias towards certain outcomes.
A full RNG evaluation will include:
The General RNG Analysis is an investigation of the general functionality and implementation of the RNG. This General RNG Analysis may include the following:
The DIEHARD Battery of Tests is an assessment of the level of unpredictability of the application outcomes before scaling and mapping.
The Final Outcome Distribution Tests are an assessment of the distribution of the application outcomes after scaling and mapping.
