Your Quick Guide to Gambling & Casinos in Missouri
Thirteen riverboat casinos from Kansas City to the Mississippi River towns. Eight online sportsbooks that went live in a single day this past December. Here is where, how and what you can legally gamble on in Missouri.
Gambling Options Available to You in Missouri
Missouri's gambling landscape runs on two rivers and a single 2024 ballot measure, with one clear line: real-money online casino play has not been authorized, but licensed online sports betting has been since December 2025.
Online Sports Betting
Legal statewide since December 1, 2025, after voters narrowly approved Amendment 2 in November 2024. Eight operators launched together on day one, tethered to the state's riverboat casinos or holding one of two untethered licenses. You must be 21 or older to bet.
Riverboat Casinos
Thirteen licensed riverboat casinos operate under the 1992 constitutional amendment that first authorized "gambling excursion boats" on the Missouri and Mississippi Rivers, from Ameristar St. Charles to Century Casino Caruthersville.
Daily Fantasy Sports
DFS has been legal and regulated in Missouri since 2016 under the Missouri Fantasy Consumer Protection Act. The Missouri Gaming Commission licenses operators, and around a dozen sites currently accept Missouri entries.
Prediction Markets
Platforms like Kalshi let Missouri players trade on real-world outcomes such as sports results and economic data under federal CFTC oversight rather than state gambling law.
Horse Racing
Pari-mutuel wagering has been constitutionally authorized in Missouri since the 1980s, but no track currently operates live racing in the state, so there is nowhere to bet on-site today.
Missouri Lottery
Running since 1986, the Missouri Lottery funds education and veterans' programs through scratchers, Powerball, Mega Millions and Pick games. Minimum age is 18.
Social Casinos
Social casinos let you play slots, blackjack, roulette and poker completely free, with no real money involved, a popular way to enjoy casino games in Missouri without any financial stakes.
Online Casinos
There are no legal real-money online casinos in Missouri. State law restricts games of chance to the 13 licensed riverboats, and no bill or ballot measure to authorize online casino gambling has advanced at the state level.
