UK law is specifically applicable to places where gambling is practiced, and its main goal is to keep you safe online. This is accomplished by attempting to make internet casinos more open about the specifics of their games and by taking action against establishments that they believe are deliberately courting young people or problem gamblers. As a result, you could be prompted to sign into an account or provide proof of your age before playing any games, even those that are free. Other than this, there are no limitations on free games.
