Other than the forms of gambling specifically authorized and regulated by the state, any other form of gambling in the Show Me State is a Misdemeanor.
Missouri an Interesting State
It’s another one to watch for online gambling to perhaps be licensed and regulated by the state in the next several years. There have actually been one or two previous bills that have died a Legislative death not advancing pretty far, but at the same time, Missouri is generally fairly Liberal on casino issues. In terms of overall politics, the major liberal areas are St. Louis and Kansas City with just about everything in between being generally Conservative.

Either way...
... Missouri has had licensed and regulated land casinos for quite some time, charitable gambling is permitted in limited ways and they also have a state lottery. All of these things would seem to come together in such a way that it might make sense for the state to allow online casinos in the same fashion that New Jersey does. In fact, the parent companies of a few of the New Jersey casinos also have casino presence in Missouri already.

Gambling.
572.020.
1. A person commits the crime of gambling if he knowingly engages in gambling.
2. Gambling is a class C misdemeanor unless:
It is committed by a professional player, in which case it is a class D felony; or
The person knowingly engages in gambling with a minor, in which case it is a class B misdemeanor.
Class C Misdemeanors, which would apply to mere players, are punishable by up to fifteen days in county jail as well as fines of up to $300.
Again:
This would apply to any form of gambling that is not specifically licensed and regulated by the State of Missouri.
Operators of illegal gambling activities could be found guilty of, “Promotion of Gambling,” and would face heftier charges than would mere players. Naturally, any online casino you’re going to find on this site is housed overseas, so they are going to be out of reach of Missouri law enforcement.
We would be quite surprised...
...if Missouri never comes around and decides to license and regulate online gambling as they have already passed a Daily Fantasy Sports bill and seem quite happy with collecting their share of the proceeds on that.
Players should have almost nothing to worry about:
because we have found no instance of anyone ever being arrested or prosecuted for acting as a mere player gambling online. In fact, players who lose money by way of unlawful gambling in this state technically have the right to sue whoever they lost the money to within three months, but even if such a player were to win, Missouri does not have the legal reach to enforce collection.
For these reasons, most of the online operators affiliated with us here that operate in the United States also do so in the Show Me State, and we have listed some of them below:
