The internet brought more than a lot than what it was predicted. Who would have thought the traditional brick and mortar casinos would leap online and conquer the web?

Many times, online casinos, also known as virtual casinos, offer odds and paycheck percentages comparable to real life casinos. Some online casinos claim higher payback percentages for slot machine games, and some publish payout percentage audits on their sites online. The rules of the game establish the payout percentage for the games.

Gamers get to play online casino games either through leasing or purchasing membership quality slots online in online casino sites through companies like Microgaming, Realtime Gaming, Playtech, International Game Technology, and CryptoLogic Inc.

Some casinos offer "live gaming" exclusively or as part of a wider offering. Popular casino games such as roulette and blackjack are dealt by real dealers in casino studios in a live online casino.
