The Gaming Commission can grant or refuse seven types of licences.

In the event of an infringement of the Gaming and Betting Act of 7 May 1999 as amended by the Act of 10 January 2010, the Gaming Commission can impose administrative sanctions, ranging from a warning, to the suspension of the operation of several machines for a certain period, to the withdrawal of the licence. A sanction procedure is subject to strict rules. Any decision is preceded by extensive consultation by the Commission. Licence holders who could be facing a sanction can defend themselves before the Gaming Commission, either alone or assisted by a lawyer.

Since the Gaming and Betting Act is a criminal statute, offenders could be criminally prosecuted for some offences. The Gaming Commission can also impose fines if the public prosecutor decides not to prosecute. For this, not only the licence holders but also the players could be punished. The fines give the Commission considerable flexibility, which leads to efficient oversight.
