1. Choose one of the recommended casinos and open your account

I have gathered a list of several casinos that I recommend for you to use and apply this gaming system in practice.

I take this opportunity to remind you that not all casinos you see on the internet are reliable or offer trustworthy and properly audited gaming software.

I recommend that you use only one of the recommended casinos on this site, as I have tested them myself and applied the method in practice in all of them.

2.  Make a deposit between £150 and £750 and take advantage of the Bonus

After creating your account, it’s time to make a deposit. System 21 recommends depositing between £150 and £750 to take full advantage of the system. Depositing within this range allows you to maximize your potential earnings while managing your bankroll effectively. Additionally, many online casinos offer bonuses for new players, which you can use to increase your initial bankroll.

3. Log in and choose the Blackjack game (21)

After creating your player account and making your first deposit, it’s time to log in to the casino and look for the Blackjack game. There are several variants of the Blackjack game in casinos, but they all work the same way. Look for the Blackjack (21) game and join the game to start implementing the System 21.

4. Open the Blackjack Table and place it next to the game

Below you will find the Blackjack table I created for the application of the System 21 system. This table will help you decide what to do in each of the game’s moves.

This table allows you to always make the mathematically perfect move and try to gain an advantage over the Dealer.                             

This table is extremely easy to use. On the left side, you have your cards, and on top, the Dealer’s cards.

On the right side, you will find the legend regarding what you should do when the Dealer has a certain card and depending on the cards you have.

Example: If the dealer has an 8 and your two cards add up to 10, you should double your bet. If you have a pair of fours (4,4) and the dealer has a 10, you should ask for a new card.

And so on throughout the various moves that happen. If you ask for a new card, you should consult the table again to know exactly what to do.

Don’t forget to place the Blackjack table side by side with the game software. This way you can analyze more quickly what you need to do to always make the mathematically perfect move.

Consult the table with each move to know exactly whether to ask for another card, stand, surrender, or even double your bet.                                                                                                    

5. Apply the System 21 Method

The System 21 system logically involves not only the Blackjack table. This table helps you always make the mathematically perfect move, however, it’s also necessary to apply the System 21…

This consists of betting more money when you’re in a winning situation and less money when you’re in a losing situation.

Since you’ll never win every hand of the game, it’s important to apply these rules so that you have the best possible performance during the game:

Recommended Minimum Bet: £2

When you win a hand: Decrease £2 to the recommended minimum bet (never bet less than £2)

When you lose a hand: Increase £2

When you tie with the dealer: Increase £1

This means that when you start the Method, you’ll place a bet of £2 and ask for cards. If you win the bet, you’ll bet £2 again in the next hand. If you lose the bet, increase to £4 in the next hand. If you tie the bet, increase to £3 in the next hand.

As you apply the system in practice, you’ll realize that it’s important to gradually decrease the value of your bets as you win more and more hands.

It’s important to increase your bets by £2 when you’re in a sequence of several negative hands, so you can recover the money from all the non-winning hands more quickly. In the end, you’ll always end up beating the Dealer and the casino.

Final Thoughts

The System 21 system can be applied with higher values easily. If you make an initial deposit above £750, you can start your game with a minimum bet of £5 or £10 to scale your winnings more quickly.

However, don’t forget to apply the System 21 in the correct proportion. This means that if you make minimum bets of £10, when you lose, you should increase your bet by £20, that is, bet £30 on the next hand.

Logically, the more money you have in your bankroll available to play, the more money you will be able to win. 

While it’s perfectly possible to make a £50 profit in a few minutes with low-value bets, if you use higher minimum bets, you will triple or quadruple your profit in the same period.

However, it’s important that you’re not greedy and don’t try to win all the money in a single day.

Apply the System 21 in various casinos, and above all, the recommended casinos, which are the ones that offer the best conditions for you to apply this Blackjack system.

Good luck!
