Initial testing of the system began last month with a limited number of operators, after details of the system were announced in October.
The KSA will now expand this from 14 December to all interested land-based and igaming operators, as well as any of their potential suppliers.
Operators that secure a new online gambling licence in the Netherlands will be required to integrate with Cruks when the market opens on 1 September next year.
Once integrated, operators must check if a player has signed up to Cruks before they are allowed to register and play online games.
In October, the KSA also set out the terms and conditions for a licence application under the Remote Gambling Act, including reporting a variety of the applicant’s policies and details of how its “cooling off” requirements will be applied.
In October, the Dutch government published regulations explaining in detail how Cruks works. When a player registers with an online operator for the first time, or if the player wants to access a land-based casino, they enter their public service code (BSN), which leads to the generation of a Cruks code. This code is then compared to the list of codes for self-excluded players and if it matches, the player must not be allowed to register or enter.
