History of BlackJack

Game BlackJack came from old French game vingt-et-un (“twenty one”), though since that time it endured a lot of changes.

Nowadays BlackJack is one of the popular casino games, especially in American ones. Speaking about BlackJack profit, it has solely simple rules of game, dynamics and passion, which are always present at table for BlackJack.

At the beginning, it was considered that BlackJack as well as roulette and baccarat, has constant statistical preference to player, but as repeated scientific researches showed - it’s not true!

Firstly, every card changes the composition of the pack(shoe) in the online casino. It’s not difficult to guess, that the same card can’t come out of the pack (shoe) repeatedly. In accordance with it, counting cards, one can foresee next combinations with some exactness.

Secondly, some combinations of cards give advantages to online casino, others - to players. There is no secret that availability of great number of “tens” and aces is favourable to player and, on the contrary, small cards are favourable to online casino.

These checked facts can easily turn the advantage of casino into player’s preference. But it’s professional players’ ability to notice the changes of pack composition.

You have the unique set for playing BlackJack not only for pleasure, but for getting money!!!

Rules of BlackJack

The rules of the game BlackJack are rather simple: the player need to collect cards, the sum of the points will be closer to 21 (but not more)

If sum of points is more than dealer’s one (but less than 22), the player won. If player’s sum of points and the dealer’s one are the same, the player’s bet is returned to him (a draw). Otherwise, the dealer won.

Prize is paid 1:1

Each player gets two cards and one card is given to dealer and open. (In some game varieties dealer can get two cards - one openly, the second - “in secret”)

Having valued one’s own cards and dealer’s card, the player takes one of the following decisions:

  • Stay
  • Hit(One more)
  • Split
  • Double
  • Insurance
  • Surrender

Cards nominal in blackjack

Aces in BlackJack

Ace - 1 or 11 points (if counting ace for 11 points, the sum of cards is less than 21, the combination is called - Soft);

Tens and highcards

King, Queen, Jack and Ten - 10 points (let’s call them “tens”);


9,8,7,6,5,4,3,2 - by its nominal - 9,8,7,6,5,4,3,2 points accordingly.

Any “tens” (K,Q,J,10) and Ace give BlackJack in sum. This combination win in all cases (with the exception of the situation when dealer also has BlackJack).

BlacJack combination

BlackJack is paid 3:2

Sum in 22 points and more is bust and is lost in spite of cards, which has dealer.

How to take game decision

Stay - the player sees, that the sum of the cards, which he has got, is enough for successful game and he decides to take no more cards. Thereby, he passes the turn to the dealer (other players)

Hit(One more) - the player sees that getting sum of points is not enough or he decides to risk and takes one more card. After this a new sum is counted and a new game decision is taken.

Split - if the player has only two cards and they are the same by nominal (9 and 9, A and A, K and K, etc.), he can split cards, thereby turning one square into two. The given decision is required additional bet, which is equal to the initial one. Some casinos determine following limitations for Split:

  • After Aces split, only one card is given to each of them;
  • Split is allowed only once (if after cards split one of splitting cards got another one of the same nominal, a new split is not allowed);
  • It’s not allowed to double the bet after split;

Double (double down) - the player can double the initial bet and take only one card. Some casinos introduce limitations and allow Double only for 9,10 and 11 points.

Insurance - if dealer opened his card and it turned out ace, the player can insure against that dealer get Black Jack. Insurance is paid 2:1. Some casinos allow insurance when dealer has opened “tens”.

Surrender (pass) - the player can give up the game, having seen cards unpromising and strong dealer’s card. Thereby the half of the initial bet is lost. Some casinos allow to pass even when dealer has open Ace.

Basic strategy of Blackjack

Basic game strategy of blackjack was repeatedly counted mathematically. It’s the only one right decision in the game BlackJack on any online casino. It’s indisputable. Do not try to play without sticking to basic strategy.

Only strict following to the decisions of basic strategy of blackjack will reduce online casino advantage to minimum.

The founder of basic strategy (it is the same as strategy “Monte Carlo”) is considered Boldown. In the 50-eties, he with his colleagues has counted the most optimal variants of turns and published his works in one of the Americans magazines.

But the real upheaval in basic game strategy of blackjack, without doubt, made Edward O. Torp, who counted dozens millions of combinations and carried out the thorough analysis of situations when the player would most probably win and when he would lose.

Besides, Torp came to the conclusion that the probability of one or another combination changes with each card, which came out of the pack. (More detailed information about it is in the item "Cards counter")

Card counting

It is obvious that each card, which came out, changes the pack composition, that is it influences on combinations, which appear with more or less probability.

In order to know the pack composition it’s not necessary to count all cards, which came out in blackjack. It’s impossible to do. The basic systems of cards counting divide the pack into cards which are profitable to player and those ones which are advantageous to onlinle casino. There are a lot of differences in systems, but the scheme is the same.

In the system of cards counting by Stanford Vong (some sources give the authorship to Harway Dubner) “High-Low”, the pack (shoe) is divided into cards which are profitable to player - 10, Jack, Queen, King, Ace; and those ones which are advantageous to casino - 2,3,4,5,6. There is equal number of both types in the pack. In the beginning of the game the score is 0. When the card which is profitable to player came out, we should subtract 1 out of score. When the card which is profitable to casino came out, we should add 1. Cards 7, 8, 9 are not counted.

For example:

Cards came out 6 10 Jack 3 3 10 9 5
Count +1 -1 -1 +1 +1 -1 0 +1

Total general score will be: +1-1-1+1+1-1+0+1 = +1

It’s important to be able to distinguish between main score and true score.

Counting cards by system “High-Low”, we’ve got the information about main score and it’s rather important. But, on no account one cannot lean on this data playing game with some packs. The true score is important while playing game with some packs.

In order to determine true score, it is necessary to divide main score by the number of packs, which are left in the “shoe”. The number of packs one can determine visually or program Lazy BlackJack in online casino can do it.

If true score = +2, it makes sense to increase your bet a little, and, on the contrary, it is recommended to make minimum bets, having negative score.
