According to the rules, masks will remain mandatory and customers can visit facilities in groups of up to four people.
In addition, every betting facility must ensure 1.5 meters of social distancing, provide hand sanitisation services for staff and customers and regularly disinfect their establishment and any equipment used.
The new rules were announced on June 7.
Meanwhile, a new protocol between the Belgian Gaming Commission and the federal police was also announced.
It includes a request from the Gaming Commission to access federal personal data in order to identify a visitor to a class I or II gaming establishment as a member of the Integrated Police, and subsequently ban them from gambling.
The protocol also outlines that new data should be transferred daily in order to keep up with additions and losses of staff to the Integrated Police force.
Last week, the Gaming Commission revealed that it had issued 55 sanctions for 23 cases in 2020.
