What is CRUKS?

The Centraal Register Uitsluiting Kansspelen (CRUKS) is a gambling self-exclusion system and database in the Netherlands. It is used to maintain a list of users which have decided to exclude themselves from gambling and is used to stop them from registering and playing with licensed gambling operators. 

How does CRUKS work?

Users are able to access the CRUKS system through their DigiD (a Dutch ID system for online services and government websites). They can then register with either their public service number, surname, and date of birth, or, if they are not a Dutch citizen, with official documents like a passport. 

A user can also be directly registered by a Kansspelautoriteit employee if they do not have access to the DigiD system.

The user will then be able to generate a CRUKS code, this code is used when registering for or accessing a gambling service. Then, the code is compared to a list of codes in the CRUKS system and if the players’ code matches one that is self-excluded, they will be blocked from accessing any gaming services.

CRUKS also generates aggregated metrics that relate to the number of queries and excluded players. This can be used to measure the system's success and, importantly, does not include data about any gaming habits. 

The system came into effect as of March 1, 2021. 

CRUKS Compliance

In order to be compliant with new regulations, operators will have to use the CRUKS system and correctly check users against the self-exclusion database. This means regulators must now do the following:

Any licensee’s gaming system must automatically consult the Netherlands Gambling Authority’s Central Register every time a player signs up, to check again the CRUKS database. The player’s CRUKS code must be checked and they must only be allowed access if it is confirmed they are not in the register. 

A service interruption protocol must also be in place, which should consult and sign out CRUKS players after the interruption has been resolved, or keep track of users and their activity during the interruption. 

What does the KSA do?

The CRUKS is maintained and managed by Kansspelautoriteit (KSA) - the Netherlands’ official gambling regulatory authority. This means it is in charge of gambling licensing and regulations within the Netherlands. 

The KSA works to protect and keep users safe, as well as create a compliant, safe, secure and responsible gaming environment by working alongside operators. This includes enforcing and maintaining current regulations, alongside bringing into effect new systems, such as CRUKS.
