Understanding Gambling Laws in Missouri
Missouri law prohibits gambling outside of licensed venues such as state-sanctioned casinos. According to RSMo § 572.010, gambling is broadly defined and includes any contest, game of chance, or wagering activity where something of value is risked on an uncertain outcome. This includes poker games, sports betting, internet gambling platforms, and using gambling devices like unregistered slot machines.
Charges often arise when authorities allege that someone has profited from facilitating or participating in unauthorized gambling activities, even in private residences or online environments. Even playing in what seems like a harmless “friendly game” may result in misdemeanor or felony charges depending on how the law is interpreted.
