Online Casino games are mainly playable in the browser plugins like Flash, Macromedia Shockwave, or Java and require browser support for these plugins. Online casinos offer free credits or free chips on sign-up. Some casinos offer Live gaming, either exclusively, or as part of a wider online casino offering. In live online casinos, popular casino games such as roulette and blackjack are dealt by real dealers in casino studios, in an attempt to convey more of the atmosphere of a physical casino. Player actions in the game of blackjack may be transmitted to the dealer; in some online casinos more than one player may sit at a particular seat on the table, and in this case there is no interactivity between player and dealer, the question of the player’s requested the extra card that the dealer dealt and which chose to stand will be handled by the software. It is usual for the players to be able to observe a video feed of the action, and equally common for players to opt to turn it off, if they lack the bandwidth – as the cards are read by OCR and other technology, the video feed is only ever a visual cue. Some online casino games are Baccarat, Blackjack, Craps, Roulette, Online slot games, online poker, Keno Bingo and so on.
