An online blackjack game can be rigged in a number of ways. One way is to allow the dealer to shuffle the cards before each hand. This allows the casino to determine the order of the cards, which can help them to better predict which hands will be profitable. Another way that a casino could rig an online blackjack game is by allowing the player to see the card before it is dealt. This allows the player to know what card they are going to receive, which can help them to make better decisions with their cards. Finally, casinos could also manipulate the payouts in an online blackjack game.
By randomly selecting which hands are paid more than others, it is possible for a casino to give the illusion of being a fair game. However, this could actually be a form of rigging the game in favour of the casino. Ultimately, it is difficult to determine whether or not an online blackjack game is rigged. However, if you feel that you are being treated unfairly or that your chances of winning are decreasing, it may be worthwhile contacting customer service and asking them about your concerns.
