In August 2008, Prairie Band filed a lawsuit against Harrah's to enforce a non-compete agreement with Harrah's, after Harrah's involved itself in a proposed casino in Sumner County. Earlier that year, the Prairie Band Potawatomi Nation sued the state of Kansas in a bid to stop legislation that would allow four state casinos and slot machines at horse and dog tracks.

In April 2007, Harrah's Prairie Band Casino in Mayetta was the largest casino in Kansas. Management for Harrah's Prairie Band Casino-Topeka transferred to the tribe on July 1, 2007, which was ahead of the scheduled termination date by nine months. The new logo featured 'a flame, a traditional Potawatomi symbol, and a diamond to represent gaming.' The transition from Harrah's to the tribe took place on July 1, 2007, with the casino renamed Prairie Band Casino and Resort. In May 2007, the casino unveiled a new name and logo after it prepared to assume complete control from Harrah's. In May 2005, the casino announced that Harrah's would not be renewing its management contract, which expired in January 2008. It was the only of the four casinos in Kansas at the time that had a hotel. Highway 75 traveling north from Topeka read 'Harrah's Prairie Band Casino, 12 miles.' At the time, after opening, the 100-room hotel adjacent to the casino was 'generally full' with reservations recommended. When it opened on January 12, 1998, the entertainment complex was 63,000 square-feet. The casino and resort opened in 1998 as the first full-service casino in the state of Kansas. The casino also has three restaurants and 297 guestrooms. The casino is open 24 hours daily and has a 35,000-square-foot (3,300 m 2) casino, with 1,090 slot machines, a bingo hall and 31 table games. It was originally operated by Harrah's Entertainment under a management agreement with the tribe until July 1, 2007, when the tribe took over operations.
