Frequently Asked Questions

Yes, System 21 is a system that allows you to always make the mathematically perfect play in the game of Blackjack.

It is completely free and available on this page for anyone who wishes to apply the concept in practice at one of the Recommended Casinos.

The system does not cost any money; it is entirely free, and you can use it as many times as you like, including recommending it to your friends.

£15 – £75: It’s not enough money to recover losses after a series of less favorable results.

£150: You have to make bets with much lower values, which hinders your chances of making money.

£240: The casino realizes that you are only trying to win bonuses. Withdrawals are too high.

£300 or more: Generally, people who follow the system to the letter actually make money.

That’s why I suggest an initial deposit of at least between £150 and £750, which, as explained in the Method demonstration, is the safest way for you to play and have a comfortable bankroll to apply the system in practice with guaranteed results.

The more money you put into a casino, the more bonuses you will receive, and the more money you will have available to apply the Blackjack system in practice.

This will allow you to place minimum bets with higher values and make more money in the same period of time.

There are several ways to withdraw money from online casinos, and you should choose the one that suits you best.

I recommend that you always opt for electronic wallet services like Moneybookers, Paypal, or Neteller, which allow you to transfer money to your bank account easily afterward.

You can also choose to make a bank transfer directly from the casino to your bank account if you prefer.

If you deposited with a Credit Card (VISA or MasterCard), you can also withdraw the money directly to your card.

All the Recommended Casinos on this site offer a bonus for new players, ranging from R$200 to R$5000, depending on the casino.

Check out the offers available on the site and take advantage of those that offer the best bonuses for you to start with the maximum amount of money possible.

This way, you’ll have a larger bankroll and will be able to make more money in the same amount of time.

The System 21 is timeless, meaning you can apply it whenever you wish. Also, recommend it to your friends, and don’t forget to apply the method in multiple casinos simultaneously.

This will help you spread out your money gains and remain unnoticed, which is important when applying this system in practice.



The System 21 is 100% safe and legal. Playing at online casinos is not illegal in Brazil, contrary to what many users believe.

The method itself is perfectly safe as well, since when applying the Method in practice, you are simply playing Blackjack perfectly and without tricks.

The perfect play in Blackjack only depends on you knowing in advance whether you should hit or stand, double your bet, split, or simply stay as is. This is not illegal; it’s just playing Blackjack.

This system is innovative and aims to help you understand which actions to take at certain moments in the game. You just have to use the chart and apply each of the tips whenever you are dealt cards.

By playing according to what the chart says and applying the right playing strategy (see how the Method works), you are mathematically advantaged over the Dealer, which is why you win. In addition to being safe and legal, System 21 is a system with guaranteed results!

Good luck with your bets!
