According to RTS 7, Random Number Generators must be tested in order to verify the compliance of the following qualities:

1. the output from the RNG is uniformly distributed over the entire output range and game, lottery, or virtual event outcomes are distributed in accordance with the expected/theoretical probabilities.
2. the output of the RNG, game, lottery, and virtual event outcomes should be unpredictable, for example, for a software RNG it should be computationally infeasible to predict what the next number will be without complete knowledge of the algorithm and seed value.
3. random number generation does not reproduce the same output stream (cycle), and that two instances of a RNG do not produce the same stream as each other (synchronise).
4. any forms of seeding and re-seeding used do not introduce predictability.
5. any scaling applied to the output of the random number generator maintains the qualities above.
