ECOGRA, iTechLabs, GLI and other slot auditors - what is it
Independent slot auditors are specialized companies that test slot machines and other gambling for integrity and compliance with stated characteristics. Their main task is to confirm that the results are generated randomly, and the declared percentage of return to the player (RTP) corresponds to the real one. Such checks are mandatory for licensed casinos and are carried out according to regulatory requirements.
1. Why do you need auditors
Exclude the possibility of fake results.
The correct operation of the random number generator (RNG) is confirmed.
RTP stability is checked over a long distance.
Ensure the confidence of players in casinos and game providers.
Allow regulators to control market integrity.

1. Obtaining a sample game - the laboratory receives game code or access to the test environment.
2. Analysis of the RNG algorithm - checking the randomness of the results.
3. Mass testing - millions of simulations to detect deviations from the declared RTP.
4. Comparison with a theoretical model - results must meet statistical expectations.
