Rampart Casino, Casino at JW Marriott Las Vegas Resort, Nevada.

Rampart Casino is a gaming venue located within the JW Marriott Las Vegas Resort in the Summerlin area. The facility features a large gaming floor with slot machines, video poker stations, table games, and a separate bingo room for visitors.

The project was announced in 1996 as The Resort at Summerlin, developed by Seven Circle Resorts and designed by Paul Steelman. It opened on July 15, 1999, after delays including the 1999 Las Vegas flood, with a 286-room tower and casino. A second tower opened in January 2000, and the property was renamed The Regent Las Vegas. After Chapter 11 bankruptcy in November 2000, Hotspur Resorts bought it in 2001 and rebranded the hotel as JW Marriott; the casino became Rampart Casino in 2002 under Millennium Management Group.

The casino's name comes from the Rampart Casino branding adopted in 2002 by Millennium Management Group, which held a 10-year lease. The property appears in the first seven seasons of the CBS series CSI: Crime Scene Investigation as the casino owned by Sam Braun, father of character Catherine Willows. A sports betting center operates inside the casino.

The casino offers complimentary outdoor and indoor parking along with electric vehicle charging stations for guests. Service and gaming run around the clock, making the venue accessible at any time of day or night.

The Player Portal system lets members check their loyalty tier status and redeem accumulated points through computers or mobile apps. This digital platform provides each visitor with tailored offers based on their gaming behavior and preferences.
