A casino, also known as a gaming house or a gambling hall, is a place where people can play various games of chance for money or other rewards. Most of these games are conducted by employees known as croupiers, and the odds on each game are determined by statistical probability or by random number generators. Some casinos offer only table games, such as blackjack or roulette. Others have a mix of both table and slot machines. A few casinos focus on traditional Far Eastern games, such as sic bo, fan-tan and pai gow.

Gambling has been part of human culture for millennia, with evidence dating back as early as 2300 BC in China. More recently, the first modern casinos appeared in Atlantic City, New Jersey and on American Indian reservations, where they are not subject to state anti-gambling laws. Casinos are also found on cruise ships, in Las Vegas and on many international destinations, and they are also increasingly available online.

A casino is a tourist attraction for visitors and locals who seek excitement and fun. Some of the biggest casino resorts are located in exotic locations like Venice, Monaco and Singapore, with their glitzy surroundings and dazzling displays of lights and sounds. These casino hotels are also home to top-rated restaurants and nightclubs that feature popular DJs and local acts. Some of them also feature a golf course, rooftop pools and water slides. They also feature high-end spas where guests can relax and indulge in their favorite treatments.
