The Biggest Blackjack Mistakes to Avoid at Online Casinos

The advent of online gambling has made it more convenient than ever to play at the blackjack table, and unfortunately, easier to make blackjack mistakes. You can choose either the traditional video game-like virtual blackjack, or feel like you are at a real table with an interactive dealer.

Live dealer blackjack is the most realistic offering for an online casino game. Whatever version of blackjack you are playing online, it’s important to avoid common blackjack mistakes. Making blackjack mistakes can quickly burn a hole in your bankroll.

Being perfect and never making a mistake at the blackjack table is not possible.

The goal is to limit your blackjack mistakes to get the most out of your money. You can’t win every session, but avoiding common blackjack mistakes will facilitate more of them. By all means, if you aren’t looking to win money and just want to blow time, what do you care about making blackjack mistakes?


Online blackjack is different from some in-person blackjack tables. You won’t be able to find an online dealer that isn’t using a continuous automatic shuffler, most often with six or eight decks. They are becoming more common at land-based casinos, too, but there are still some traditional games available that don’t use a shuffler.

Why is this important? Counting cards at an online casino is a waste of time. You are going to use too much time and energy trying to count cards against the live dealer. Even if you have success, the online casino algorithm will pick up on what you are doing.

You aren’t the only one that may make blackjack mistakes. Blackjack dealer mistakes are something to watch out for online.

Some online casino operators may be shadier than others. This is why TheSportsGeek has compiled a list of the best and safest blackjack sites. Head below to find the top common blackjack mistakes to avoid.

Common Blackjack Mistakes

1. Betting on a Hunch/Not Using Basic Strategy

Betting on a hunch and pressing because you think you’re going to be lucky is not the best blackjack strategy. This goes for any form of gambling, but even more so blackjack because there are basic strategies that you can employ, unlike other casino games.


That you shouldn’t stand on a 16. Statistically, you are better off hitting a 16. This is no man’s land and it’s a tough spot to be in, but the math says to hit.

Do you have a hunch that a number is going to hit on roulette? Okay, fine, go ahead and have fun. However, with online blackjack, there is a basic strategy that you can follow. This doesn’t involve a faulty system or card counting.

Following basic strategy, which is following the math, is how you should be gambling on blackjack. This is not true for advantage players, but again, carding counts online is a lost proposition.

Print out a basic blackjack strategy cheat sheet or have one up on your screen while playing online blackjack. You may not feel comfortable doing this at your local casino, but it’s our secret online.

2. Betting at a Table With Poor Blackjack Rules

This can be applied to any casino, land-based or online. One of the dumbest things you can do is play a 6:5 table. These are not as common online, but they are out there.


Stay away from tables that pay out 6:5 for a blackjack. In other words, you are voluntary improving the house edge by 1.40% on a 6:5 table. Instead, search out online blackjack tables that only pay out 3:2 for a blackjack.

For sports bettors that go by American odds, the 3:2 translates to +150, and 6:5 pays out +120 for a blackjack. That should be the only convincing that you need for your next blackjack session. This brings us to our next point, which is prevalent in online casinos.

3. Playing Side Bets and Bonuses

The side bets and wild bonus bets that online casinos offer have terrible odds. This is one of the most common blackjack mistakes that gamblers make when making their bets. Yeah, sure the payouts and enticing, but that’s the point.

The casino is attempting to lure you in to make a bad bet, and online casinos are the worst offenders for side bet temptation.

Land-based casinos may have side bets, but online operators have the luxury of implementing different types of side bets quite easily into their software. They will continue to come up with new and attractive side bets, but be aware, that this is a big blackjack mistake.

4. Splitting Tens/Buying Insurance

This is another red flag that must be highlighted. Splitting tens for a chance at drawing two face cards to double up sounds awfully tempting. However, don’t do it and opt for the more conservative route.

The odds suggest that you should hit and play for a face card or another 10 being dealt.

It’s likely you’ll play at live dealer tables online where players will split their 10s. Don’t follow the crowd and follow our advice and the math. There are situations where you should hit, but this isn’t one of them.

Insurance? Again, the odds tell us to pass. If insurance didn’t work in the house’s favor, they would not be offering this option.

5. Chasing Your Blackjack Losses

This can get out of control in a hurry online. The accessibility of online gambling is a blessing and a curse. It’s great to be able to play blackjack at home, and even with a live dealer on your computer or cell.

If you are having a losing session, get off the online casino. Better yet, close the internet browser and do something else. Play with the dog, go for a walk, but don’t do anything gambling related if you’re on a cold run.

After you clear your head, this is when you can go back to playing blackjack. You may not have this opportunity if you blow your bankroll in one session.

6. Playing Blackjack at Unreputable Online Casinos

You want to get paid after you win at the blackjack table, right? The internet is cluttered with online casinos that only want to scam you for your hard-earned money.

There have been online blackjack scams, either rigged virtual games or shady dealers. From slow-paying, locking you out of your account, or rigged games, there are many scams that they can get you with online.

For the best blackjack sites, we highly recommend only wagering at the casinos from our list. This might be our most important advice for betting on blackjack online.


There are many benefits to playing blackjack online. Online operators are making it more convenient and intuitive than ever to provide a realistic experience. However, it’s important not to fall into a blackjack mistake that can derail your bankroll.

If you want to have the best experience possible, avoid these common blackjack mistakes to maximize your potential. There isn’t any shame in betting using basic strategy and following the math.
