Be sure to visit one of the best blackjack casinos, like Betsson, Lapalingo, or Dunder, if you want to make the best use of these tips!

Splitting 8s and Aces

If you want to know when to split and when to avoid splitting, you might want to read a thorough guide on this subject. However, there are two types of pairs that you should always split – no matter what the dealer has. If you have a pair of 8s or a pair of aces in your hand, you must always split them.

The reason why this is a must is that you’ll have fantastic offs of winning both hands simultaneously if you split them. Any card valued 10 or 11 (should you be lucky enough to get another ace) will give you a very strong and a massive chance at beating the dealer.


Sure, if the dealer has a 10-valued card on their first hand, you might want to rethink your strategy. In most cases, though, you’ll want to have a go at splitting. Many newcomers to the beautiful game of blackjack tend to make the terrible mistake of splitting 10s, as they think that they’re going themselves a favor by multiplying the odds, whilst splitting 8s might not be an intuitive play at all.

Veterans will tell you otherwise, though. Math proves why the RTP of blackjack is low if you’re a newcomer without proper strategic knowledge of the game.

Never Split 10s!

As we just said, splitting 10s is one of the worst mistakes that you can make as a new blackjack player. You can read our full blackjack basic strategy guide if you wish to learn why this isn’t a smart play. However, if you’re a season blackjack veteran, then you probably know why. Splitting 10s destroys a fantastic 20-valued hand, which is something that you’ll never want to do.

You can end up betting twice the amount of money that you were originally going to bet, and lose both hands instead of winning just one. Splitting 10s is actually a play that screams greediness. You need to play smart if you are to win. Not every large bet will translate into a smart play – this is something that you need to keep in mind if you want to make a killing in rewards in the long run.

Blackjack is a game of small and even wins, not a game of large profits. Split only when you need to – don’t do it out of greed.

Double Down on a 10 if the Dealer Has a 2

We just told you that splitting 10s is a terrible move. However, that doesn’t mean that you can’t take full advantage of a hand with a value of 10 (be it either a hard 10 or a soft 10). If the dealer has a 2, you’ll want to double down on your 10. You can turn that hand into an extremely profitable play if the dealer has a two, because chances are that the dealer will go bust, whilst you’re likely going to get a 20 or a 21 on your next card.


Basically, it’s smart to double down on a 10 because you have high chances of getting a fantastic hand whilst the dealer is highly likely not going to do anything but go bust. Always remember that, in blackjack, there are a ton of cards with a value of 10, plus a handful of cards with a value of 1/11 in the aces. Soft hands won’t help the dealer if they get a two, whilst hard values of 10 will prove to be detrimental for them.

Never Buy Insurance

Newcomers tend to fall victim to the insurance scam – and we’re not referring to traditional insurance scams performed by people who want to make some extra cash by throwing themselves in front of a bus. Buying insurance in blackjack is rarely a smart play. In fact, it’s one of the worst things you can do in the game.

It can be very tempting to buy insurance when you see that Ace on the dealer’s hand, but trust us – the odds of you putting that insurance to work are very low. In only 30% of occasions during a blackjack hand will your insurance prove to be useful. Do you really want to risk that extra cash for a 30% chance of you losing money?

We would rather stay with the 70% chance of us not losing against that ace on the dealer’s side. Sure, they will either end up with a blackjack or a solid soft hand. Still – it’s not worth the risk! 


Read the Rules – Play with Dealers that Stand at Soft 17

Any blackjack table will put the odds against you. There isn’t a single online casino or even land-based casino in which the player could put the odds in his favor. However, that doesn’t mean that you should play in any table regardless of the rules. Certain blackjack tables give the player far better odds than others – even when no strategy is being put into place.

That means that reading the rules can prove to be quite an effective strategy on its own. You don’t need to be a master of the game to know that some rules can prove to be catastrophic for the player in the long run.

The one that we mostly recommend our readers to watch out for is the rule that makes dealers hit at soft 17. If the dealer has a soft 17 and they can hit, they have a good chance of coming closer to 21 or even getting a better value than your own. Stick to playing in blackjack tables that offer the rule of the dealer standing at soft 17.

Your odds will be much better and you’ll need to take fewer risks in order to beat the house – especially if you already have an 18 on you!

Raise Your Bet When You Win

Although this might seem a bit intuitive at first glance, one of the best ways for you to play as a beginner is to only raise your stake whenever you win. There are gambling strategies and methods that recommend you to increase your wagers whenever you lose in order to attempt to get the money back, but those can be detrimental to your bank balance if you’re not an expert on the game.

If you don’t wish to stick to basic blackjack strategy and you would rather use more complex betting methods, it is recommended for you to be a bit more of an expert.

Newcomers that attempt to use methods such as the Martingale strategy or the Fibonacci strategy can end up losing quite a lot of money in the long run. However, if you stick to only raising your bets whenever you win, chances are that you will end up making far more money in the long run.

We do recommend lowering your stakes whenever you lose, as to avoid losing too much money and draining all of your bank balance. Raising your bets in a smart manner is basically a way of adapting the Martingale system to blackjack. If you wish to learn more about this brilliant betting system, you might want to check out our guide on the best roulette strategies that can help you get a strong grasp of the concept.

Stick to Blackjack Basic Strategy Guidelines

We’ve written a blackjack guide already, so you might want to check it out if you truly wish to understand all of the in and outs of one of the world’s most popular card games. The basic blackjack strategy gives you the best mathematical odds of winning at blackjack.

Every single play has been calculated by experts in the past, and they have thankfully shared their masterful knowledge with us mortals. That way, we know which bets we should make and when to take risks.

It’s a fantastic way to approach blackjack. Just remember that basic blackjack strategy guides aren’t flawless. Even when using a guide, blackjack is an unpredictable game that can be troublesome to understand. However, memorizing every play of a blackjack basic guide will give you the best odds of winning at the beautiful game.

You’ll find that some of the strategies that we’ve listed here form part of a major list of blackjack strategy guidelines that players can choose to follow in order to maximize their odds of winning at the game. We want you to make a killing in rewards after you finish playing, so stick to these guidelines to maximize your profits!

Use Betting Systems that are Proven to Work

Betting systems that are mainly used to play roulette, such as the Martingale system, can prove to be extremely effective when you take the challenge of playing blackjack online. You can check out our guide of the best roulette systems, found at The Casino Wizard, if you wish to find out which of these are suited to work in a roulette table.

You can’t expect to use the James Bond strategy in blackjack, of course, but systems such as the Martingale are perfectly suited to be used in tons of table games and even in certain online slots.

Once you’ve gained enough experience at the game, you can start mixing strategies with one another. Some players love to combine certain betting systems to see if a mix of two could yield better results. However, we do not recommend doing this if you’re a beginner. It can be difficult to determine which changes to make to a system if you wish for it to remain profitable!

Be sure to master these systems first by playing free roulette or free blackjack in any of your favorite online casinos. Most sites give you the option to try out certain games without spending a dime, but using virtual currency instead. Use the virtual cash to determine how much money you’re winning or losing before deciding which system to play with real cash.

Use the 1-3-2-6 Betting Strategy

Don’t be deceived by the name of this strategy; you don’t need to be a mathematical genius if you wish to make it work. In fact, the name just comes from the way you’ll be placing your bets when going on a winning streak at blackjack. This strategy was originally designed to work in roulette, poker, and baccarat.

However, players that manage to achieve a long winning streak in blackjack can adapt it to make it work fantastically well on this game, too. The strategy can actually be used on any game that pays even money.

You will need to assign a monetary value to a unit before we begin. Each unit will represent one number of the sequence of this method. Let’s portray this with an example, as it will help you get a better grasp of the system much quicker. We will assign a monetary value of €10 to each unit for this example.

With that in mind, picture the sequence at the name of this strategy: 1-3-2-6. The first bet will be worth €10 (one unit). Should you win, the next bet will be worth €30 (3 units). If you win once more, go for a €20 bet (2 units). Are you on a roll? Go for one more bet of €60 (6 units)!

This strategy is designed to profit from those times on which you’re on a roll. A loss using this system can hurt your pocket more than using any other system, but it’s a risk worth taking in most cases. The problem with this strategy is that its effectiveness completely depends on you being on a roll to win.

If you lose once, you’ll lose a lot of money (especially on the second and fourth bets!). Do you believe in luck and wish to give this system a go? Go for it! It’s really fun and extremely thrilling. Just be sure to set a limit to your bankroll in case you go on a streak of bad luck. It’s also a “temporary” strategy. You might want to change it if things go south.

Count Cards at Your Own Risk

Even though counting cards is a difficult system to master, some players can actually become really good at doing so. The problem with counting cards in land-based casinos is that every single establishment forbids you from doing so. As such, you can get into real trouble if you decide to try it. With that said, card-counting techniques are some of the best effective methods that you can use if you wish to make a profit while playing blackjack.

A professional card counter tends to predict which cards the dealer has or which cards are out of the game, further reducing the RTP of a game and, in extreme cases, even turning it in their favor. As you might imagine, however, it’s not possible to count cards in online casinos. Some games might allow you to do it, but it’s extremely difficult to keep a track of certain movements and draws when a game is fully digitalized.

Put Your Knowledge to the Test in the Best Blackjack Casinos

Now you know the best blackjack strategies in the world. This is going to give you a massive edge when gambling in online casinos, as you’ll be able to increase the RTP from 92% to almost 100%. Turning a disadvantageous game into one that you can honestly profit from goes a long way towards the betterment of your iGaming skills.
