Where To Play Blackjack Online

These are our favourite sites for Brazilian players to play blackjack-21 online:

While online blackjack-21 can seem a bit intimidating, the game is actually much simpler than it seems. Put simply, the goal in blackjack-21 is to attain cards that total closer to 21 than the dealer, without going over.

The first action to take place when you sit down at an online blackjack-21 table is to make a bet. Depending on the amount you have in your bankroll and the table you choose, you can bet anywhere from 50 cents to hundreds of reais on any given hand. While playing blackjack-21 online, you simply click on the denomination you want to bet and then put it in the middle of the table.

Here’s a hand of blackjack-21 in five simple steps:

1. Make your bet
2. Receive cards from the dealer. You’ll be dealt two cards, as will the dealer. One of the dealer’s cards will be face up.
3. Decide to hit (take another card), stand (decide to take no more cards), double down, or split. More on this step later.
4. Repeat until you’re satisfied with your cards’ total
5. Await dealer’s hand for result

How to Win at Blackjack-21

Manage Your Bankroll

This bears repeating for all types of online gambling – have a bankroll strategy and stick to it. In blackjack-21, we recommend ensuring that each individual bet represents – at most – 5% of your total bankroll. For example, if you have $100 to play with, we recommend playing $5 hands at most.

Never Chase Losses

Blackjack-21 in particular is a game of math. If you play wisely and follow sound strategy, you will gain the edge over the long term. Do not play recklessly and emotionally, and never abandon your strategy to win back anything you’ve lost.

Capitalize on Good Hands

Use splitting and doubling down to maximize your bet amount on good hands. In online blackjack-21, being aggressive is required at times. If one more ten would give you a winning hand, take a calculated risk and double down.

What is “Blackjack-21?”

Blackjack-21 is both the name of the game, and the name of a winning hand.

If any player – you or the dealer – receives an Ace and a ten-value card (i.e. a ten or a face card) as your initial two cards, this is called blackjack. In this instance, the player dealt the blackjack automatically wins this hand.

What is a Bust?

You’ll note that we keep mentioning not to go over 21. If your cards add up to more than 21, this is called a ‘bust’, and means you lose that hand and your bet.

If, once you and the dealer are done taking cards, you have a higher hand than the dealer and you didn’t go over 21, you win! Typically, you earn back your original wager, plus that same amount again. For example, if you wager $10 and win, you’ll be paid $20.

If, once you and the dealer are done taking cards, you end up with the same total, this is called a “push”. This is essentially a tie, and your original wager will be returned to you.

When to Hit, Stand, Double Down or Split

After the bets are placed and each player has received their two initial cards, you’ll have to choose whether you want to hit, stand, double down, or split. You’ll want to make this decision based on what’s in your hand, and what’s showing in the dealer’s hand.

When to Hit in Blackjack-21

“Standing” is choosing to receive no more cards from the dealer.

A player would “stand” when they’re confident they have a high enough hand to beat the dealer, typically on hands that total fifteen or more (depending on what the dealer is showing.)

When to Double Down in Blackjack-21

“Doubling down” is choosing to double your original bet and committing to receiving only one more card from the dealer.

As an example, a player should generally “double down” if their hand totals 10 or 11, as the odds of the next card being a ten or face card is in the player’s favor in the long run. Again, this will depend on what the dealer is showing as well as the casino’s dealer rules.


Remember – doubling down doubles a player’s bet, and they only get one more card. If the player gets a good card and win, they win double, but if they get a bad card and lose, they’ll lose double.

When to Split in Blackjack-21

A “split” is only an option when a player is dealt a pair. “Splitting” a pair turns the original pair into two separate hands, doubling the amount of hands the player has on the table and doubling the player’s current bet.

For example, if a player was dealt two 8s, they could split these. They would then have two hands worth 8 each, and receive an additional card for each hand. They’d then play these hands the same way they’d play one – choosing to hit, stand, double down, or even to split again.

Choosing when to split is a bit complicated, and depends on which pair you receive, and what the dealer’s showing. When you’re choosing to split, remember these three things:

  • Don’t split a winning hand. If you’re dealt two 10s, it’s tempting to double down, but don’t. If you’re dealt two 10s, you know you have twenty, which is likely a winning total. Hold tight.
  • Only split good cards. Remember, you’re turning these cards into new hands, so only split cards that you actually For example, if you’re dealt a pair of fours (a low, mathematically unfriendly card) there’s no point in splitting – you’ll just end up with extra hands full of fours.
  • Each time you split, your bet doubles. Just try to remember what you’re getting into – splitting doubles your potential winnings, but also your potential losses.


Different Types of Online Blackjack-21

When you decide to play blackjack-21 online, you have a host of options when it comes to the different variations of the game. Here are a few of the most popular options for Brazilian players, but rest assured, there are plenty of other games that follow the objective of blackjack-21.

There are also different payouts when a player hits 21. Whether it’s 5,6,7 card 21’s or three suited 7’s.

Live Dealer Blackjack-21

In this popular Blackjack-21 variation, players can enjoy a traditional casino experience while playing online as there is a live dealer in real-time dealing the cards. Live blackjack-21 is a great option for players that want the live casino experience with the convenience of playing from their laptop or mobile device.

European Blackjack-21

European blackjack-21 is a popular variation with minor differences from traditional real money blackjack-21. One central difference is it only played with two decks of cards, where others use six to eight decks. There’s no hole card in the European variation of the game and the dealer doesn’t receive a second card until the player has completed their hand. Doubling down is also limited. In European blackjack-21, players can only double down if they have a hand of 9 through 11.

Single Deck Blackjack-21

This version of blackjack-21 is only played with one deck. For years, single deck was the standard, but casinos began to mix in multiple decks to make card counting more difficult.
