In general you need to have a
gambling license in each country you want to offer your product.
There are several countries without a gambling law and poker rooms were operating there until recently, but now they are asked to withdraw from all the countries in the 'grey zone'.
I suppose Unibet will go back to these countries but the order would be like
-a country establishes a new gambling regulations
-Unibet applies for the gambling license
-Unibet allows the citizens of this country to play
that means it may take some time before the restriction are lifted.
