Blackjack is the traditional form of 21 that can be found in casinos all over the world. That includes online casinos, where it can be given additional side bets and gameplay elements that simply aren't possible at a physical table. In any form, blackjack remains extremely popular because it can be learned quickly and provides some of the most favorable odds of any casino game to those who master its basic strategy. As it doesn't need many fancy bells and whistles, it can be offered as a no download game rendered through Flash or Java for fast table game action.
Almost everyone is familiar with the basics of blackjack, where players try to get as close as possible to 21 without going over while also finishing with a better hand than the dealer. Every card is worth its printed value except for face cards, which all have a value of 10, and aces, which can be counted as one or 11 as needed. The dealer must stop at a particular value (usually 17) while the player can take as many cards as desired. Reaching a total of 22 or higher is called busting and automatically loses a player's wager; it pays all players still in the hand when a dealer does the same. A blackjack occurs when an ace and a 10-value card arrive on the first two cards and usually pays out at a higher rate than normal wins, which are paid at even money. Most games of blackjack have additional rules and player options that come into play in specific situations.
Blackjack is one of the most common games found in no download casinos because it doesn't need complex graphics or a complicated interface to play. No download blackjack operates in a browser window or a dedicated pop-up window and usually runs with little lag or delay. Some online casinos also offer live blackjack tables where the bets are made virtually but the cards are dealt by human dealers in front of cameras that send out live streaming video. Live blackjack tables are best played over faster internet connections to handle the video feeds, but otherwise play the same as other online games with the added perk of human interaction.
