Online casinos are now even more popular than brick and mortar casinos since players can enjoy the same games and win the same prizes without having to leave their home. The odds and payback percentages are pretty much the same as land casinos. Online casinos use software companies to power their games. These include companies like CryptoLogic Inc, International Game Technology, Microgaming, Playtech and Realtime Gaming.
There are generally three kinds of online casinos, download, mobile, and flash casinos. Flash casinos allow users to play without downloading anything. The game is played directly from the web browser. Mobile casinos allow game play through an HTML interface so players can use their iPod, iPad and iPhone to play. Download-based online casinos require a full download in order to play and wager on the casino games offered.
