Can Online Casinos Rig Blackjack?

Blackjack is one of the most popular casino table games and is played around the world both in brick-and-mortar casinos and online casinos. While many players enjoy the game for its entertainment value, there are always concerns about fairness and integrity. With online casinos becoming more prevalent, many players wonder if online casinos can rig blackjack games to their advantage.

Understand How Blackjack Works

Before we dive into whether or not online casinos can rig blackjack, it’s important to understand how the game works. In blackjack, players aim to get a hand that’s as close to 21 as possible without going over. The dealer deals two cards to each player and two cards to themselves, with one of their cards facing up.

The player can choose to “hit” or “stand” after seeing their cards, trying to get as close to 21 as possible without busting. If the player busts (goes over 21), they lose the hand. Once all players have finished their turns, the dealer reveals their second card and hits or stands according to set rules.

Online Casino Regulation

In order for an online casino to operate legally, they must be licensed by a reputable regulatory authority such as eCOGRA or the Malta Gaming Authority. These regulatory bodies ensure that online casinos operate fairly and transparently by conducting regular audits of game software and random number generators (RNGs).

RNGs are algorithms that determine which card is dealt next in a game of blackjack or any other casino game. They’re designed to ensure that each card has an equal chance of being dealt, regardless of what’s come before it.

PRO TIP:When playing blackjack online, always make sure the casino is licensed and regulated. This ensures that the games are fair and there is no risk of the casino rigging the game. Additionally, look for casinos that are independently audited by a third-party to ensure that their games are fair and random.

Potential for Rigging

While reputable online casinos are required by law to use RNGs, there’s always the potential for a rogue casino to rig games to their advantage. This is why it’s important to only play at licensed and regulated online casinos that have a proven track record of fairness and transparency.

One way that a rogue casino could rig blackjack is by using a biased RNG. For example, if the RNG is programmed to deliver more low-value cards than high-value cards, the dealer would have an advantage over the player. However, this type of behavior would be quickly detected during regulatory audits.

Another way that a rogue casino could rig blackjack is by manipulating the game software itself. For example, they could program the software to deal winning hands to specific players or increase the house edge on certain bets.


While there’s always the potential for a rogue online casino to rig blackjack games, reputable online casinos are required by law to use fair and transparent gaming practices. By playing at licensed and regulated online casinos with a proven track record of fairness, players can rest assured that they’re getting a fair shot at winning.
