An online casino, also called virtual casinos or Internet casinos, are internet versions of brick and mortar casinos. Online casinos allow gamblers from around the world to play and participate in casino games via the Internet. It is also a very popular form of internet gambling. The popularity of online casinos is due in large part to the fact that they are available twenty-four hours a day, seven days a week.

In Las Vegas, online casino gambling has gained a measure of popularity among the many other forms of casino gambling there are. Las Vegas is perhaps the foremost place to find a legal casino, and one of the most well known. Virtually every casino in Las Vegas can be found online. Many Las Vegas hotels offer online betting on their Las Vegas Hotels, and many shows, including Cirque du Soleil, have web sites that offer free video streaming to their guests.

Las Vegas is home to some of the most famous gambling games in the world. There are slots, blackjack, poker, bingo and many other types of gambling games. While it is difficult to give a complete list of all the available online casinos, Las Vegas is perhaps the best known gambling destination, and has even received some criticism from some quarters because of this. However, the increased popularity of Las Vegas slots and gaming tables has also increased its popularity nationwide, and casinos in almost all major cities throughout the United States are now offering gambling opportunities to internet gamblers.
