A) Return rate of each casino game and other gambling

Among the many gambling games, online casinos boast an outstanding return rate (the percentage of the amount players spend on their hands).


Online casinos have a high return rate because they have a structure that can suppress "capital investment costs" and "labor costs", which are considered to be the largest expenses in company management, by completing the service on the Internet without having a store.


As you can see in the table, you can see at a glance that the return rate of online casino is overwhelmingly higher than general other gambling, but this fact is surprisingly unknown for generals.


・ Isn't online casino a scam?

・ Isn't it difficult to play?

・ How do I get started?


Like the above concerns, It may be another reason why the hurdle "looks high" for beginners who do not know anything.

B) Why we choose Blackjack in the many casino games

As mentioned earlier, online casinos offer high returns, but among them, blackjack and baccarat have the highest return rates.


It's a simple and obvious reason, but the high return rate of the base is a very important reason.


By applying a mathematical method (card counting) to this high return rate, it is possible to create a situation where the return rate exceeds 100% (= the amount returned is greater than the bet).

C) What is card counting?

Card counting is to predict the cards that are not yet in play (cards in the shooter) by recording all the cards that are in play and calculating.


The remaining cards in the shooter will change as the game progresses, and there is sometime an inclination to a certain card, so the idea of ​​card counting in blackjack is to definitely calculate that inclination and utilize it.


For example, suppose there are three J / Q / K cards each.


And, suppose JJQQQ comes out when you draw 5 cards.


Then, the next card you will draw will be one of JKKK (rest of cards).


So which card is likely to be the next card?


.....That's right.

Expecting K is the most probable in terms of probability theory (K will be drawn in 75%).


Simply put, this is card counting.

1. Why Blackjack


A) What kind of game is Blackjack?

Blackjack is a game in which cards other than the Joker are used, and the one (dealer or player), getting the total number of cards dealt is 21 or closer to 21, wins. (Lose if exceeding "21" as it is "Bust")

First of all, various cards are calculated as follows.



"10 / J / Q / K"

: Calculated as 1 or 11.

: Calculated as each number

: Calculated as 10


● Player's basic actions ●





: Draw another card

: Finish the action without drawing a card

: Double the bet amount and draw another card

: Divide the dealt cards into two and play each separately

● Dealer's basic actions ●


    After player's action, just draw a card up to getting dealer's total number of cards more than "16".

* The above rules may differ in each online casinos.

Let's play demo.


The dealer first deals two cards each, leaving one of the dealer's cards prone.


Then, player considers if draw or not, for the total number of cards to be closer "21".

In this case, player should draw a card because present total number of cards is still "11" ( 8 + 3 ), which means player calls "Hit".

After player's calling "Hit", dealer deals one more card.


Considering that it is now "19", player calls "Stand", because it is more likely to exceed "21" if more cards are drawn.


After player's action, dealer confirm prone card and draw a card up to getting dealer's total number of cards more than "16".

Dealer's cards are now "15", so dealer need to draw a card to exceed "16".


When the dealer draws a card, K (= calculated as 10) comes out, and the total number gets "25".
Since it exceeds "21", it becomes "Bust", which means 
player wins.


This is one game and will be repeated.

One more thing, dealer draws cards from the shooter being consisted of about 3 to 8 sets (1 set has 52 playing cards). The number of cards depends on each online casinos.


For example, Infinite Blackjack suitable Blackjack for PCS uses 8 sets (52 x 8) of cards as one shooter.


While one shooter has a huge number of cards, conversely, only that many cards will come into play, so we can probabilistically predict the next one card. Therefore, various strategies have been created.


The most famous method among the strategies is "Basic Strategy".

B) What is Basic Strategy?

By comparing the two cards dealt to player and the up card dealt to dealer, you probabilistically calculate and decide whether you should draw a card or compete with dealer with cards you already have, and the one summarized those logic is Basic Strategy.


In other words, when playing the game, if you play while looking at the table below, you will win only by that.


By playing games based on Basic Strategy, blackjack return rate without counting can further increase.

Basic Strategy Table.png

<How to use the table>

Check the number on dealer's up card and the numbers on player's card, and you make the next best choice.

C) Fatal shortcomings of Basic Strategy

First, there are four major ways to increase the return rate of Blackjack.


Use Basic Strategy

Do card counting

Control bet amount

Build logic optimized for each casino's Blackjack rules

Of the four, Basic Strategy in ① has some major shortcomings.


those are,,,


● Only the same play can be shown under any circumstances

● Not judge if you should bet strongly or not

● Only show hands based on general Blackjack rules

Then, Let's see the detail reasons.

Only the same play can be shown under any circumstances

This happens because Basic Strategy only shows the average value.


For example, Basic Strategy shows recommended plays that take "K" into consideration, despite the relative frequency of "K" being zero.

In other words, Basic Strategy can not show a best play according to a running play.


Consider the case which the dealer has "5" as up card and player has cards as a total number of "16".

Basic Strategyの表2.png

At this time, player should choose "Stand", in light of the table of Basic Strategies.


The reason why it is considered to be "Stand" in Basic Strategy is that 10 / J / Q / K calculated as 10, have a high appearance rate, so dealer is likely to be "Bust" in this situation.
(goes like 5 → 10 → 10, and it means a total number as "25", which is "Bust")


However, as the game approaches the end, there is a possibility that 10 / J / Q / K calculated as 10 get exhausted and the appearance rate can be extremely lower than usual.


At that time, if choose "Stand", it may not be the best hand.

To avoid this, 

Do card counting

would be a solution.

● Not judge if you should bet strongly or not

Basic Strategy only shows the next hand, there is no bet amount guide.


In general, the situation which many cards calculated as 10 came out (= the situation which there are few cards calculated as 10 in the shooter) is considered to be an advantageous situation for dealer, and conversely it is considered to be an advantageous situation for player when a lot of low cards (2 to 9) came out.

Strictly speaking, the favorable / disadvantageous situation changes from moment to moment depending on how many and which cards appeared.


Therefore, no matter how much the online casino and Blackjack use Basic Strategy, even if it is a high return rate, if the bet is not made when it should be bet, the profit amount will decrease greatly.


In the situation which you win three times when you bet $100 each and lose once when you bet $500, you will be in the red even if the winning percentage is high.

win rate x payout.png

To avoid this, 

Control bet amount

would be a solution.


● Only show hands based on general Blackjack rules

Blackjack rules vary slightly from casino to casino.

Here are some excerpts of parameters in the return rate due to differences in rules.


In this way, if the rules are different, the return rate also changes.

Each parameters are not so big, but when they are added together or we play longer, the results are greatly affected.

So, you can see that Basic Strategy created according to the general rules does not show the optimal play for you.

To avoid this,

Build logic optimized for each casino's Blackjack rules

would be a solution.
