It is common practice for online casinos offering blackjack games to also offer you blackjack bonuses. Blackjack bonuses are essentially free money in exchange for signing up or blackjack that has been played already. Free money comes in the form of welcome bonuses, deposit bonuses, sign up bonus, refer a friend and loyalty points. Another way that casinos offer you free online blackjack games is by offering you practice play sessions, 1 hour of free play as well as just for fun games. Of course you can not win real money from these games.
Blackjack bonuses are a way of enticing you to play blackjack online for real money at their casino. However online casinos are not charities they are running a business and all businesses want to make money. By giving you free money you may well continue to play just at their casino but they are aware that there are other casinos offering similar or the same free blackjack play online and you may play at their casino. More importantly though you may be a blackjack bonus abuser, that's someone who plays the minimum amount to cash in the bonus hoping to make a profit. Obviously casinos do not like these players and have rules to try to prevent this happening.
Next whilst most casino games are a game of chance now there is no possible way that you can win, blackjack is just a little bit different. Blackjack is a not a game of chance but a game of skill and there before it is absolutely possible to win. Using correct blackjack strategy means that a player can reduce the casino's edge and sometimes get an advantage.
For these reasons any free blackjack money offered as an enticement to join the online casino has a wagering obligation attached and why this wager requirement generally has to be sent on games other than blackjack. Any free money offered has a wagering requirement attached. Generally the more generous the bonus, or if it's too good to be true it's likely that they will have imposed a larger wagering requirement for the bonus. Again blackjack is a game of skill and can be won and for this reason blackjack games either or not count at all or count as a very low percentage towards meeting the requirement. These requirements are structured and in place to offset the risk that a casino takes by offering bonuses to its players. The casinos are simply protecting themselves by ensuring that you spend some money on other games within the casino before you run away with your winnings.
Of course it's not guaranteed that you will win, you still need to learn basic strategy and learn how to manage your bankroll. But the casinos still need to protect themselves. They do not want players who are excellent at blackjack strategy, unemotionally attached to any losses made and counting cards at the same time. The online casino would lose the free money they had given you plus whatever you won. Whether you can card count online is debatable because the deck is shuffled after every hand in non live games and half way through live games, meaning that a count can not be kept. It is extremely illegally that using this card counting method in live or non live games you will gain an edge over the house.
In summary free online blackjack games do not really exist in the form of a blackjack bonus due to bonus seekers, bonus abusers and the ability to beat the house with basic strategy. It is possible to find a free game look out for offers such as "Win Real Money - NO Deposit Required" of course these are hard to come by and you often need to e-mail them instead of just signing up, so it makes it a little bit more difficult to acquire and there are still certain restrictions placed upon these bonuses before you could cash out any winnings. Make sure you read the terms.
