Online casinos are, basically, the counterparts of real-life casinos that can be found in cities like Las Vegas and Atlantic City. They include basic casino games, like Craps, Blackjack and Roulette. You buy chips and play either against the house or against other opponents. Most of today's online casino games include software that you download onto your computer, creating an almost-real simulation of a casino table or setting.

Sports betting websites involve placing bets or making wagers about sporting events, such as football, baseball or hockey. The websites usually include all kinds of information about the sport, such as current player or team statistics, coach biographies, history and more. They have less flash than online casinos, and are designed more for utilitarian purposes.
