The Hard Rock opened with a 28,000 sq ft (2,600 m²) casino, which included 800 slot machines.
By June 2005, the Hard Rock's Peacock Lounge had become one of the first venues in Las Vegas to use "smart" casino chips embedded with radio-frequency identification hardware.
As of September 2008, a $30 million poker room had been opened in the casino, replacing a cigar shop.
The poker room measured 7,000 sq ft (650 m²) and included 18 tables.
Following the resort's 2007-2010 expansion, the casino measured 61,704 square feet (5,732.5 m²).
Up to that time, the casino portion of the resort had not been a significant source of revenue.

In February 2010, the Hard Rock signed a deal to begin offering eDeck portable devices, created by Cantor Gaming.
The eDeck allowed customers to play gambling games in non-gaming areas of the resort such as bars, restaurants, and near the pool area.
Simultaneously, the Hard Rock launched an effort to attract Asian gamblers, a group who had frequently played at other resorts on the Las Vegas Strip.
The casino began offering popular Asian games such as baccarat, and the resort also scheduled several events to celebrate the Chinese New Year.
Later that year, modifications were made to table games and slot machines in an effort to appeal to local gamblers.
Cantor also began operating a sports book at the resort.
A high limit gaming area was added in 2012.
At the time, Asians made up 10 percent of the casino's clientele, and the Hard Rock hoped to increase the figure to 30 percent within a year.
