St. Louis Area Casinos: The Complete List [2026 Guide]

This page is the St. Louis area's commercial casino registry, pulled from our statewide venue tracking of 13 licensed commercial casinos across Missouri, verified against Google Places data as of September 2026. Four of those 13 sit in the Greater St. Louis metro, and this guide covers all four with the rating, review-volume, and hours data we have on file.

The St. Louis Cluster

Casino	City	Google rating	Google reviews	Hours
Ameristar Casino Resort Spa St. Charles	St. Charles	4.2	14,857	Open 24 hours, every day
Horseshoe St. Louis	St. Louis	3.9	12,152	Not yet published on this listing
River City Casino	St. Louis	4.1	10,009	Not yet published on this listing
Hollywood Casino St. Louis	Maryland Heights	3.9	9,592	Not yet published on this listing

All four are commercial, state-licensed casino venues rather than sweepstakes-model platforms — a different category from the online operators covered elsewhere on this site. Ameristar Casino Resort Spa St. Charles is the only one of the four with confirmed round-the-clock hours in our data; the other three haven't had hours data published on this listing yet, and we'd rather say so than guess.

Highest-Rated: Ameristar St. Charles

At 4.2 stars across 14,857 Google reviews, Ameristar Casino Resort Spa St. Charles carries both the highest rating and the largest review count of the St. Louis cluster. It's also the newest addition to our tracking and doesn't yet have its own dedicated review page on this site — that's coming as we build out full venue profiles.

Most-Reviewed Runner-Up: Horseshoe St. Louis

Horseshoe St. Louis sits second by review volume at 12,152 reviews with a 3.9 rating. It's followed by River City Casino (10,009 reviews, 4.1 rating) and Hollywood Casino St. Louis in Maryland Heights (9,592 reviews, 3.9 rating). All three have full review pages on this site with more detail than fits in this list.

St. Louis in the Statewide Picture

Missouri's registry runs 13 licensed commercial casinos in total. St. Louis's four-venue cluster is tied with the Kansas City area (also four venues) for the largest concentration in the state; the remaining five are split across Southeast Missouri (two), Northern Missouri (two), and Central Missouri (one). If Kansas City is closer to you, our Kansas City venue and Harrah's North Kansas City pages cover that cluster.

Here's the full statewide registry for context, sorted by region:

Casino	City	Region	Google rating	Google reviews
Ameristar Casino Resort Spa St. Charles	St. Charles	St. Louis Area	4.2	14,857
Horseshoe St. Louis	St. Louis	St. Louis Area	3.9	12,152
River City Casino	St. Louis	St. Louis Area	4.1	10,009
Hollywood Casino St. Louis	Maryland Heights	St. Louis Area	3.9	9,592
Ameristar Casino Hotel Kansas City	Kansas City	Kansas City Area	4.1	16,435
Harrah's North Kansas City	North Kansas City	Kansas City Area	3.9	13,380
Argosy Casino Hotel & Spa Riverside	Riverside	Kansas City Area	4.1	10,099
Bally's Kansas City	Kansas City	Kansas City Area	3.6	6,994
Century Casino Cape Girardeau	Cape Girardeau	Southeast Missouri	4.0	3,533
Century Casino Caruthersville	Caruthersville	Southeast Missouri	3.7	2,637
Mark Twain Casino	La Grange	Northern Missouri	3.6	1,636
St. Jo Frontier Casino	St. Joseph	Northern Missouri	3.5	2,561
Isle of Capri Casino Boonville	Boonville	Central Missouri	3.8	3,863

By review count, the St. Louis and Kansas City clusters dominate the state: all four St. Louis venues and three of the four Kansas City venues top 9,500 Google reviews each, while the Southeast, Northern, and Central Missouri venues each sit under 4,000. That gap likely reflects metro population more than venue quality — a smaller-market casino with 1,600 reviews and a 3.6 rating isn't necessarily a worse experience than a big-metro venue with 14,000 reviews, just a less-visited one.

How We Source This Data

Every rating, review count, and hours line on this page comes from Google Places data pulled against each venue's listed business profile, cross-checked against the operator's own website where one is linked in the table above. We don't survey visitors ourselves for this page and we don't average in review sites beyond Google. That keeps the numbers narrow but verifiable — if a rating or review count on this page ever drifts from what you see searching the venue directly, the venue's own listing is the more current source, and we'll update ours on the next data pull.

What This Data Doesn't Tell You Yet

We're publishing exactly what we've verified and no more. Three of the four St. Louis venues don't have posted-hours data in our tracking yet, and we don't have amenity, parking, or dining data for any of them on this page. If you need same-day hours confirmation, call ahead or check the operator's own site — we'll add hours here once we've verified them directly rather than guess based on typical casino patterns.

No. These are commercial, state-licensed casino venues you visit in person.
