Ameristar Casino Resort Spa St. Charles

Ameristar Casino Resort Spa St. Charles is a riverboat casino located on the Missouri River in St. Charles, Missouri, a northwestern suburb of St. Louis. It is one of several casinos in the greater St. Louis market. It is currently owned by Boyd Gaming. Ameristar attracts over 5.5 million visitors a year and is one of the most visited tourist attractions in Missouri.

History
The casino opened on May 27, 1994, then owned by Station Casinos under the name Station Casino 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. Due to regulations of that time, admission fees were charged, and gambling sessions were restricted to two-hour cruises with a $500 maximum loss per session. In late 1994, the casino was moved to a new boat, the Station Casino Belle. Cruising was required until 1996, when a change in regulations allowed riverboat casinos in Missouri to be permanently moored. For some time, two casinos were actually operating, one on the boat and another on a barge, until 1999, when the entire casino was consolidated to a barge, partially due to a regulation change which eliminated boarding restrictions. In October 2000, Station Casinos sold its Missouri properties, also including Station Casino Kansas City in the deal to Ameristar Casinos. In 2008, a major expansion of the property included a hotel, pool, and spa. In 2013, Ameristar Casinos was acquired by Pinnacle Entertainment. 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.
