How Much Does It Cost To Develop 21 Blackjack Game?


Blackjack 21 is a unique casino card game that is both a luck-based game and strategy-based game just like Rummy. Although it originated in France, the 21 Blackjack game can be played anywhere in the world now. This is possible due to 21 Blackjack game development that can be used to create an app. After hearing this, every entrepreneur would naturally question the “cost to develop 21 Blackjack game?”

How To Play 21 Blackjack Game

“How to play 21 Blackjack game”, will be a common search term for prospective app users. To raise awareness about the strategy behind this game, here are all the 21 Blackjack game rules and regulations.


The aim is to make a sum of 21 without going over this figure. However, you can’t let the dealer reach 21 before you!

Card Vaules


  • By default, dealers will provide each user with a card facing upwards in clockwise rotation, including themself.
  • However, all users except the dealer will receive a card facing upwards again for the second round.
  • In a live Blackjack 21 game, the player holds and conceals the cards. But, in most virtual games, cards are not concealed and are visible to everyone.


In the event that a player receives 21 points in two cards (an ace and a face card), the user has a ‘natural’ or “blackjack.” If the dealer does not have 21, they must pay 1.5x the player’s bet.
But, if the dealer has a ‘natural,’ they will collect all the bets of the players who don’t have a ‘natural.’


Initially, players will be given two cards. After this, they can choose to:

  • Hit- be given another card to get closer to attaining 21.
  • Stand- hold onto their remaining cards till the next round.
  • Occasionally players may exceed 21 when selecting a hit. By 21 Blackjack game rules the player would be “bust” and cannot continue playing.
  • Another exception exists as a “soft hand,” this is when users can count an ace as 1 and not 11 if they are about to become bust, allowing them to continue playing.

While all players have their cards faced upwards, the dealer will have their first card dealt upwards and the second card dealt downwards. Post dealing two cards to each player, the dealer must turn over the second card. If the dealer has a total of 16 or less, they must draw a card. If a sum of 17 or more is collected, the dealer must stand. At all points after this, dealer decisions are automatic, but users can choose their fate.

Split a Pair

When playing, users may receive identical cards in the first two hands. In such cases, the player may consider them as two different hands. The bet would be doubled, as the second card bears the same bet value.

As a result, players can alternate between their two hands at each turn. But, this could be a bane and not a boon if applied incorrectly.

Double or Nothing!

The ‘double down’ stance in the Blackjack 21 game is a possible opportunity to double your bet by 100%. However, one should be completely confident about their hand before doing so, as you are running the risk of losing twice as many chips as before. Here’s when to double down:

  • Total of 11
    When your two cards collectively create 11, you have a high chance of getting 21 or as close to it as possible. Hence, doubling down would be the desirable move to increase your profits.
  • Hard 9 or 10 (a hand without an ace)
    If you have cards that total a hard 9 to 10, and the dealer has a considerably lower total, you are in a position to double down!
    You are probably more likely to hit 21 or closer to it than the dealer, which is why it is a good option.
  • Soft Hand of 16 to 18
    A soft hand means that your hand comprises a card plus an ace. Now, remember that an ace could count as a 1 or a 11, depending on the need of the hour.
    This occasion is great to double down. Drawing a high card could be corrected by treating the ace as a one and not an eleven.

Never Double Down In These Circumstances!

Doubling your bet is not always the best option.

  • Dealer With an Ace
    Naturally, if the dealer has an ace or a face card, they are in a good place to hit Blackjack or close in on that number.
  • Sum of 11 or More
    Another situation in which you should avoid doubling down is if your cards total 11. The chances of going bust are too great, so the reality of losing your bet is also high.
  • Unsure
    Another instance where you need to think carefully is if you are unsure of the direction your fate may turn. It does not always go your way when you decide to double down. In many cases, players who frequently double down do not experience much success!
