To play at an online casino you must be at least 18 years old, or of legal gambling age in your country of residence: whichever is the older. Most casinos are not designed to appeal to children and will make every effort to prevent minors playing at their online casino. Unfortunately, though, no system is infallible, and some young people will not be detected. If you are aware of any person under the age of 18 gambling online, then please contact the casino in question.
