Gaming Laboratories International (GLI) operates as a gaming industry testing and certification laboratory. The testing facility is operated in over 10 offices to better deliver independent testing. GLI offers complete testing and certification services for all types of online gambling systems operators, including online casinos, poker rooms, bingo, sportsbooks, etc.

In order to get a GLI certificate of integrity and seal of approval, an online gambling software vendor or online gambling business operator needs to submit all hardware and software utilized for random data generation. Also the licensee needs to supply GLI with a submission letter that should incude the following information:

Game parameters and rules including the number of selections within one game or draw, range and if the numbers are drawn with or without replacement, for example Keno, 20 numbers drawn from 1 through 80 without replacement;
A description of the RNG including seeding method, frequency and size of the seed, all key functions involved in the RNG process and type and location of the RNG algorithm that is used;
An explanation of any differences between how the data is drawn for the test application and the production application;
Software version(s);
A documented list of changes that have been made to the program since the last version that was submitted for the jurisdiction;
GLI Verify signatures or equivalent;
Hardware requirements and specifications;
Testing expectations;
Billing expectations;
Intended RNG report recipients;
Primary contact(s) and contact information for all questions.

The application used to generate the random data must be as close to the final production application as possible with regard to the RNG implementation. Therefore, it should use the identical function(s), calls, variables, scaling methodology, etc. as the production software. The manufacturer shall disclose any differences between the test application and the production application.
