How does online blackjack prevent card counting?

Introduction to Card Counting in Blackjack

Card counting is a technique that is used in blackjack in order to increase the player’s chances of winning. This technique involves keeping track of the cards that have already been dealt in order to determine which cards are more likely to be dealt in the future. By tracking which cards have already been dealt, the player can adjust their betting strategy to increase their chances of winning.

Card counting is not illegal, but it can be difficult to master and is generally frowned upon in live casinos. As such, online casinos have implemented various measures to prevent players from using this technique to gain an advantage.

How Does Online Blackjack Prevent Card Counting?

Online blackjack uses a variety of methods to prevent players from counting cards. These methods include:

  • Random Number Generators (RNGs)
  • Continuous Shuffling Machines (CSMs)
  • Multiple Decks

Random Number Generators (RNGs)

Random number generators (RNGs) are used to ensure that the cards are dealt randomly. This eliminates the ability for players to count cards, as there is no way for them to predict which cards will be dealt.

RNGs are also used to determine the outcome of other games such as roulette, slots, and baccarat. This ensures that the games are fair and that players have an equal chance of winning.

Continuous Shuffling Machines (CSMs)

Continuous shuffling machines (CSMs) are machines that are used to randomly shuffle the cards before each hand. This makes it impossible for players to count cards, as the cards are shuffled after each hand.

The use of CSMs also eliminates the need for manual shuffling, which can be time consuming and prone to mistakes. This makes the game faster and more efficient.

Multiple Decks

Some online blackjack games use multiple decks of cards. This makes card counting more difficult, as players have to keep track of multiple decks of cards at the same time.

Using multiple decks also increases the chances of the dealer having a blackjack, which can make the game more interesting and exciting.

Online blackjack has several advantages over playing in a live casino. These advantages include:
