Ameristar Casino Resort Spa St. Charles

It was one of the first two riverboat casinos in the state, and originally offered 24,500 square feet of gaming space with 52 blackjack and craps tables and 813 video poker machines.

Cruising was required until 1996, when a change in regulations allowed riverboat casinos in Missouri to be permanently moored.

Pinnacle Entertainment was acquired by Penn National Gaming in 2018, but it chose to sell 4 of Pinnacle's properties, Ameristar Casino Kansas City, Belterra Casino Resort & Spa, Belterra Park and Ameristar St. Charles to Boyd Gaming to ensure regulatory approval.

Many experts see a trend in casino consolidation, especially in markets such as Missouri, as a means of cutting costs.

The casino currently includes over 2,000 slot machines as well as table games and a poker room.
