Game systems: the practical details
Logos from test laboratories should connect to an identifiable certificate, game version and scope. A copied badge is not independent evidence.
Key distinctions
- RNG outcomes should be unpredictable.
- Testing scope can cover software rather than the casino.
- Operator conduct sits outside pure game mathematics.
Put the information to use
- Identify the game provider.
- Verify the test claim.
- Match certificate scope.
- Check operator legality separately.
