The term “gambling activities” refers to games in which a fee is charged for the chance of winning and the likelihood of winning is entirely or predominantly based on chance. In any case, the likelihood is definitely based on chance if the decisive event is an uncertain occurrence or outcome of a future event. In light of this, (sports) bets, for example, constitute gambling activities.
In some jurisdictions, gambling activities are subject to certain legal and regulatory restrictions. In Germany, gambling is regulated by the State Treaty on Gambling.
