The Dutch government is having some success in managing its online betting and poker market ahead of regulation.
The sites are closing in the hope of getting a license to operate in Holland when the liberalisation of the gambling market takes place.
Earlier this year the Dutch Supreme Court ordered the online gaming companies to install software which would identify and block Dutch citizens.
In 2010 a government commission recommended the opening up of the gambling market but the process of adoption by the state has been slow and largely stalled.
