Blackjack is one of the most popular card games. It has gained its popularity due to its simple rules and a variety of variants of the game. Blackjack is played at home with friends, in land-based and online casinos. Ethereum cryptocurrency casinos have also embraced the game.

For customers who are just diving into the world of cryptocurrency, we will tell you about one of the popular decentralised blockchain platforms – ETH.

Ethereum is an open-source decentralised blockchain platform on which developers can create and deploy smart contracts and decentralised applications (dApps). It was first launched in 2015 and its native cryptocurrency is Ether (ETH). The token is considered the second most popular after bitcoin and it is actively used by developers to implement it into online casinos.

This page presents the best sites for blackjack on Ethereum, how to play blackjack, choose a casino and become a customer.

Rules of the game

Blackjack is one of the most famous card gambling games. The popularity of the game is due to the simple rules that become clear after two or three hands. The birthplace of blackjack – France in the XIX century. Parisian gambling establishments at that time offered guests to play vingt-et-un – ‘twenty-one’ in French. The game was widely spread first to neighbouring European countries and then to other regions. Card games were in similar form in different parts of the globe, which eventually served as a quick adoption of the new gambling pastime.

Blackjack is popular on par with poker and does not give up its position. The game is played not only in casinos, but also in the evenings, gathering with friends or family. The secret of success is in the simple rules, as well as in its dynamism and fascination. To win, you must surpass your opponents by the number of points, but do not cross the threshold of 21.

The game starts with choosing the size of the bets and their placement. Then the dealer deals two cards face up to all players. The dealer also puts two cards to himself, but one of them is revealed. Next, the player can make several decisions:

  • stop, not taking an extra card, but staying in the game – usually the decision is made if the sum of points is close to 21;
  • to top up – ask for one more card;
  • double the bet and take one card from the deck;
  • split if there are two identical cards in hand;
  • refuse to continue, surrendering the cards and losing half of the bet.

After the players have finished, the dealer takes the cards until he has 17 or more. The croupier is not allowed to double, split or surrender, and all players win if the dealer loses. If a player has 21 points on the first hand, he wins the hand, the only exception being if the dealer has the same combination. A set of 21 points from two cards is called a natural or blackjack.

In the game, cards from two to ten are evaluated according to their value, that is, they give points in accordance with the number indicated on them. Jack, queen, king give the participant each ten points. Ace brings eleven points. If the combination on hands above the 21st, the ace will add one point. The suits in blackjack do not count.

Types of blackjack games with Ethereum

It is safe to say that blackjack does not go out of fashion due to the variety of such games and side bets that players can make. The variety and the element of players influencing the outcome, make 21 the perfect tool for betting in cryptocurrency. Let’s talk about the main versions of the game that blackjack casino sites support.

American blackjack is a variant of the game with six decks. In the rules of the game is the possibility of splitting the hand, if the player received at the first distribution of two cards of the same denomination, there is the possibility of doubling the bet. In American blackjack, there is a betting insurance if the dealer has collected a natural blackjack. The dealer uses a soft bet, he cannot complete cards if he has already collected 17 points.

European blackjack uses two to eight decks, so keeping track of the number of cards in a hand is almost impossible. In the European version of the game, there is no option to split the hand. The dealer takes a card on the soft 17 and stands on the hard 17. Players can double down on the hard 10 and take insurance. The game allows the use of betting strategies and tables.

In Blackjack Switch, players are dealt two hands instead of one. The player then has the choice of whether or not to switch the top cards. Since this increases the chance of getting a natural blackjack, payouts are 100% of your bet instead of 150% (3:2). An interesting rule of thumb is that if the dealer scores 22, it’s a draw instead of a loss. Keep this feature in mind when you play.

Of the other varieties of blackjack, we can highlight single and live blackjack. The former uses one deck rather than several. Since one deck is used, it is important to show more skill to get a good result. Here it is easier to track the movement of cards, as there are a limited number of them. In single blackjack, the return percentage reaches 99.5%, which means that the casino has an advantage of only 0.5%. The second type of game is live blackjack. It can be played according to different rules and its peculiarity is that the cards are dealt not by a programmed algorithm, but by a live dealer.

How to start playing blackjack on Ethereum

Blackjack sites on Ethereum are characterised by additional game features. They should be taken into account, because when you work with the portal for a long time, you may want to play other games. The higher the variety, the easier it is to find a suitable option. Blackjack sites for ETH are distinguished by a variety of bonus features and financial opportunities. All this should be studied before registering on the portal.

The very process of making a blackjack bet includes the following steps:

  • selecting a casino;
  • creating an account
  • account top-up;
  • selecting games from the general list;
  • placing a bet;
  • receiving winnings;
  • leaving a request for withdrawal.

In detail, let’s break down the key points in choosing a playground, analysing the casino’s features, registering on the portal.

How to choose a reliable site for the game

Honest casinos with replenishment via Ethereum must operate under a licence, but this is not the only condition for choosing a reliable partner. When choosing a casino for betting on ETH, it is important to consider additional factors: security, reliability, reputation, the size of the player pool, the quality of the support service and the convenience of betting from mobile devices.

Licence

Like traditional casinos, gaming portals with ETH support are required to obtain a licence. It confirms the legal status of the project. Honest operators draw up documents in regulatory organisations of different jurisdictions. These can be offshore zones such as Curaçao, Gibraltar, Costa Rica, Isle of Man and others.

Regardless of the jurisdiction that issued the licence, the casino must post information about the document on its website. More trustworthy are the portals that have a licence validator. It is located at the bottom of the home page. Clicking on the verifier icon opens a page with all the information about the issued licence. Here you can find out the operator’s name, licence number, contacts and a link to the official website.

The presence of a licence gives a guarantee of client protection. If the casino violates the rights of users, they can appeal to the regulatory authorities, which is fraught with the revocation of the previously issued permit.

Safety

Honest Ethereum-based casinos are secure as they use encryption mechanisms. Casinos request less information from players than traditional bookmakers, with a better developed approach to security and protection of personal information.

Players’ opinions

When studying gaming portals, you can not ignore the opinions of previously registered users. The presence of a large number of complaints reduces the reputation and attractiveness of the casino. Most of the negative reviews are related to account verification, cutting limits and long withdrawals.

The presence of negative reviews should not discourage you completely. Problems in customer service can also occur at honest casinos if bettors have not carefully studied the user agreement. If you find complaints, then pay attention to the reaction of the casino administration. If the support service responds to negativity, it speaks about the care about users.

Gameplay

When choosing a casino on ETH with blackjack, it is important to pay attention to the variety of games, as this affects the player’s options if he decides to play other titles on the portal. Supporting cryptocurrency in blackjack does not prevent you from adding slots, cards, roulette and other table disciplines from well-known providers. The more games and the more diverse they are, the more interest users show in the project.

In addition to blackjack, a casino site can have:

  • online slots;
  • live casino
  • roulette;
  • crash games;
  • card and table games;
  • poker;
  • sports betting and cyber sports.

The top portals offer users more than 2000-3000 titles and up to 1000 events in the sports line, if the site has sports betting and cybersports.

Betting from a mobile phone

All modern gambling sites have in their arsenal adapted for smartphone screens mobile versions. It has a similar design, but the interface may differ. It is deliberately lightened, adapting to the small displays of smartphones with touch controls. They remove unnecessary banners from the screen or make them smaller, and all sections are placed in a hidden menu. The user calls it when the need arises. This is done for the convenience of players.

In terms of functionality, the mobile and desktop versions are no different. For the convenience of users, casino sites provide access to the mobile application. It can be downloaded to a smartphone with iOS and Android. The application allows you to save Internet traffic, since some of the information is already stored in the memory of the phone.

Customer support service

The level of support training at different casinos can vary greatly. On reliable gaming sites, fast and competent support is available for arising issues. They relate to registration, bonus activation, payment transactions and other aspects.

For a prompt response to questions from players, casinos create an online chat. It works around the clock. Thanks to modern technologies, passive support is built into the online chat, which reduces the load on operators and allows them to answer the most complex queries in more detail. In addition to online chat with the support team, players can use email and a hotline.

Advantages of cryptocurrency casinos over traditional ones

There are three main advantages of cryptocurrency casinos over traditional casinos: faster deposits and withdrawals, low casino advantage and bigger bonuses.

Cryptocurrency transactions are usually processed faster than traditional financial transactions. This allows for faster access to winnings. There is no exact transaction time, as the processing time is affected by the client’s status and the chosen withdrawal network. Regardless of the withdrawal method, 10-15 minutes is enough for the funds to arrive in the account. Another of the differences in the work of cryptocurrency casinos can be highlighted lower commissions.

Although the casino’s advantage is not determined by the method of financial transactions you use to manage your gambling budget, cryptocasinos offer more games with high RTP. This doesn’t just apply to blackjack, but also to the rest of the titles in the slot room. In slots, there are titles with a return rate of 96% and above. In card games, especially blackjack the casino advantage is not so high and in some games it is not more than 1%.

Using cryptocurrencies to accept bets, having its own token, allows the casino to provide more bonuses. This applies to the welcome reward and loyalty programme. In top casinos, cashback up to 15-20% is available, which is paid every week. Some casinos offer earnings on stacking, liquidity pooling and storing your own token.
