Fewer Decks = More Blackjacks. The main reason we say that fewer decks is better for players is that, in each deck, exactly 1/13 th of all cards are Aces.

In playing blackjack online one problem I often face is not knowing how many decks are being used. This is a particular problem with Real Time Gaming casinos. The help files often do not indicate this rule, as well as other rules, and customer support are notorious for giving incorrect information on their own rules. So I devised a test to help determine the number of decks. This test is based on the player’s first two cards and the dealer’s first two.
The following table shows the probability for various configurations of the initial four cards in blackjack. Note the probabilites for a suited pair. Of all the hands I feel this is the best to test for, given both it’s frequency and correlation to number of decks.4-Card Hand1 deck2 decks4 decks6 decks8 decks4 singletons0.6761100.636920.6185040.6125300.609573Non-suited pair0.3042500.2866140.2783270.2756380.274308Suited pair0.0477690.0695820.0765660.080006Two non-suited pairs0.0103720.0097710.0094880.0093970.009351Two suited pairs0.0002710.0005930.0007250.000796Two pair - 1 suited0.0032570.0047440.005220.0054553 of a kind - 3 suits0.0092200.0086850.0084340.0083530.0083123 of a kind - 2 suits0.0065140.0094880.0104410.0109103 of a kind - 1 suit0.0005270.0007730.0009094 of a kind - 4 suits0.0000480.0000450.0000440.0000440.0000434 of a kind - 2 suits (3&1)0.0000330.0000480.0000574 of a kind - 2 suits (2&2)0.0000170.0000370.0000450.0000504 of a kind - 3 suits0.0001360.0001980.0002180.0002274 of a kind - 1 suit0.0000010.0000020.000003Total11111
To determine the number of decks in an online blackjack game keep a tally of both the total number of hands played and the number of suited pairs. Only count a hands as a suited pair if the other two are singletons. For example one suited pair and one non-suited pair does not count. In a single deck game the ratio of suited pairs to total hands will obviously be zero. In double deck this ratio will be about 4.8%. In a 4-deck game the ratio increases to 7.0%. After that the differences are too subtle are to tell without a gigantic sample.
Of course if you ever notice three of the same card on the screen at once that rules out a double deck game immediately. Despite my lack of faith in customer support knowing their own rules I would suggest at least asking. If they give you an incorrect answer, and you can prove it, you may get some free money in your account as a way of thanks. This has happened to me several times.
Unfortunately it takes a fairly large sample size to have confidence in the number of decks between 2 and 4. After 250 hands the probability that the sample mean in a 2-deck game will be greater than 6.96% (the 4-deck theoretical mean) is 5.29%. Likewise the probability that the sample mean in a 4-deck game will be less than 4.78% (the 2-deck theoretical mean) is 8.76%. Increasing the sample size to 500 these numbers become 1.11% and 2.76%. At 1000 the numbers are 0.06% and 0.34%.Written by: Michael Shackleford
I had no idea that live blackjack online tables feature a “shoe” and not an automatic shuffle machine! I noticed it today when I checked my balance of my (almost forgotten) account at an online bookmaker that advertised their live casino games in their home page. I thought that maybe skillful gamblers can make money by card counting at these games, so I joined and tried my “luck”. The short answer is that card counters may be able to make money in the long run playing live blackjack online, but due to the slow speed of the games and the very bad penetration, they should better look for better investments elsewhere.
At first it was a pleasant surprise to find out that I could once again practice my card counting skills! It has been 10 years since the last time I visited a real casino and counted cards (read some stories about my blackjack career). Fortunately I still remembered the basic strategy and the Hi-Lo counting system, although I seem to have forgotten all the variations according to the true count. Anyway, long story short, I decided to sit down at one of those live blackjack tables, while I would be searching online for other card counters’ opinions related to these games.
It turns out that most of them complain about the speed of the games. True, just 20 hands had been dealt during the hour I spent playing live blackjack online. What is even worse is the fact that the 7-seat tables are usually full, even the ones of high stakes (50 euros minimum!). That really slows the game down.
Another discouraging fact is that players are only allowed to bet on their own hand or spot. At real casinos card counters usually bet the minimum on their hand when the odds are against them and place more bets (bigger as well) on other people’s hands when they have an edge versus the casino. In order to make money at blackjack, we need to increase our betting substantially when the “true count” number is more than two. At live blackjack online tables I wasn’t able to place bets to hands dealt next to me, or open another spot (or “box”).
To get you an idea, I would very much like to bet 5 euros per round when the casino’s edge is 0.5% against me (costing me about 2.5 cents per hand) and bet 50 euros at 3 different spots (for a total of 150 euros) when my edge is 0.5% against the casino (winning 75 cents per round). If the true count reached over 4 (more than 1% edge versus the casino), I would be willing to risk 300 euros on a single round for a nice 3-5 euros net profit in the long run!
True count is the number card counters calculate when they divide the “running count” by the number of the remaining decks. For example, if the running count is +8 and there are 4 decks still in the shoe, the true count is +2. Card counters use that number to decide how much money they would bet and whether they need to change the basic strategy. Hitting or standing on 16 against the dealer’s Ten is one of the changes that comes to mind.
Therefore, one of the most important parts of the game is knowing how many decks there are on the blackjack table. I estimated that it must have been 6 decks of cards at the table I was playing at. What’s even more important though is where the dealer places the cut card, which will signal the end of dealing the “shoe”. If they place the cut card towards the bottom of the shoe allowing 5 decks of cards to be dealt, the penetration is 16.6% (1/6) and is considered a favorable situation for the players. Depending on the penetration, the players’ edge vary accordingly.
Penetration is important because if the running count is, say 12 and the cut card is about to be dealt before the last remaining deck, we know that there are a lot of high-value cards (tens, kings, aces, etc.) in the remaining 52 cards. On the other hand, if the cut card is placed at the last 2 remaining decks, the high-value cards are scattered over 104 cards. For all we know, they can all be found at the last deck!
It turns out that when I compared casinos, most online casinos set the penetration of their live blackjack games at 50%! That means 3 decks of cards won’t be dealt out of 6! If the decks were 8, four decks wouldn’t be dealt! That is a very big disadvantage and combined with the slow speed of the games, it made me stand up and leave the table. Not before though I was dealt three 7’s!
The odds of that happening is 0.04%! Once upon a time when I was playing blackjack at brick and mortar casinos, I was dealt that very same hand twice the same night! The casino was offering a bottle of wine to any player hitting three 7’s, so I and my friend certainly didn’t leave the blackjack room empty-handed!Enjoying these posts?
