Although many online casinos offer the game of online blackjack, no one game is the same as another. Each game many offer different odds depending on the casino that it is offered at and also the version of the game. The one permanent feature of all blackjack games is the skill that is needed in deciding when to draw more cards and when to stand during the game. The skill is based on educated guesses that the player makes based on the cards in hand and the show card of the dealer. All other elements of the game are luck based as players can never predict what the initial cards will be or what further cards will be dealt. The combination of luck and skill make online blackjack the most exciting and fun of all the card games at the online casino whether players are playing for practice or real money.
