St. Jo Frontier is a riverboat casino on the Missouri River at St. Joseph, in the state's north-west corner. It rates 3.5 from more than 2,500 Google reviewers — the lowest score of any casino in Missouri, and it is worth being straightforward about that rather than talking around it.

What the property has instead of scale or polish is history.

One of the first

Missouri legalised riverboat gambling in 1993. St. Jo Frontier opened on 24 June 1994 as one of the original four casinos in the state — the first wave, before the industry became what it is now.

Three decades on it is the second-smallest casino in Missouri, which is the other half of the story. The market moved towards the large St. Louis and Kansas City resorts and this floor stayed roughly the size it always was.

What's on the floor

More than 400 slot machines and a small selection of table games, including Trilux Blackjack and Mississippi Stud.

Trilux is a blackjack side bet rather than a separate game, and Mississippi Stud is a poker-based table game against the house — a reasonable spread for a floor this size, but it is a handful of tables rather than a pit. Check the venue's site for the current table schedule before planning around a specific game.

The casino is operated by Affinity Gaming, which also runs Mark Twain Casino across the state at La Grange, and the two properties share a loyalty program and even a restaurant brand.

Dining

Three options: the Fireside Sports Bar & Grill, Winners Bar & Grill, and River's Edge Café, Buffet & Lounge.

There is no hotel on site. St. Joseph itself has accommodation a short drive away.

Tips before you go

You must be 21 to gamble, the minimum age at every Missouri casino.

The casino is not open 24 hours. It runs 10am to 2am Sunday through Thursday, and 10am to 4am on Friday and Saturday — the same schedule as its sister property at La Grange, and one of the more restricted in the state.

St. Joseph is about an hour north of Kansas City on I-29. If you are already in the metro, the Kansas City floors are considerably larger and open around the clock; this one makes sense if you are local to the north-west corner.

Nearby alternatives

South in the metro, Ameristar Casino Hotel Kansas City has 59 tables and an 18-screen cinema, and Bally's Kansas City is the compact near-downtown option. East across the state, Mark Twain Casino at La Grange is the same operator's other Missouri floor.
