Are CSMs Fair in Blackjack?

It is a question I hear fairly often: Are CSMs fair to use in blackjack? CSMs by the way are Continuous Shuffle Machines. Most blackjack players hate them. The ones that do not hate them learn to dislike them once they understand what they do. Blackjack players who count cards particularly hate them.

When a CSM is being used at a blackjack table, the dealer will collect all of the cards that were just used in the last round and pop them into the CSM. The CSM then immediately shuffles the just used cards back into the deck. At no point is there a stack of discards at a table that is using a CSM. It is the lack of discards and the constant shuffling that makes blackjack players hate CSMs.

But to answer the question, yes, CSMs are fair to use in blackjack. We may not like them, but there is nothing anywhere that says that they cannot be used. Sucks, right? Right.

Online blackjack players really do not have much to say on the idea of a constantly shuffled deck. But that is because the RNG used in online blackjack games creates an effect similar to a CSM. There are no discards in a game of online blackjack. At the beginning of a new round the RNG will pull at random the two starting cards of the player from all possible two starting cards; and will pull at random the dealer’s up card from all possible up cards for the dealer to have. Each card that is dealt is dealt from all possibilities. This is a similar effect to a CSM since the cards from a previous round are not removed from the possibilities.

Casinos can use that similarity as a means to back up the idea that it is fair for them to use a CSM. But at the end of the day, CSMs are fair game to be used in a casino no matter how much players do not like them.

Card Counting Tips: CSMs and RNGs

Well you have already had a basic explanation of how to begin card counting, but there are a few more things that you need to know before you reach your card counting glory.

There are also some blackjack games that you will want to avoid with card counting. Online blackjack and blackjack tables with Continuous Shuffle Machines. The reasons you want to avoid those blackjack games are very similar.

I will start with CSMs. CSMs are devices in which the cards from one round are fed into the device and the entire deck reshuffled before the next hand is dealt. Hence the continuous part.

This causes none of the cards that have been played to be discarded, and without discards there is nothing to count. Card counting is a way of keeping a loose running tab on the cards that have been played and removed from play under the remaining deck hits its reshuffle point. But since CSMs keep cards from being removed from play there is no point in trying to count them.

As for online blackjack, it is powered by a Random Number Generator. An RNG functions similarly to a CSM, but not exactly.

When an online blackjack game is created, its RNG is programmed with every possible outcome, such as all possible starting hands and dealer up card combinations. When a player clicks Deal, the RNG pulls from all possible starting hands and dealer up card combinations. This has an effect like a CSM because no cards are ever ‘discarded,’ it is possible for any of them to show up in the next rounds.

Because cards are not effectively discarded in a blackjack game with CSMs or RNGs card counting becomes useless in those games. It is best to stick with a standard game of blackjack in a brick and mortar casino—one without a CSM.

Blackjack with a Shoe vs. a CSM

A CSM is a Continuous Shuffle Machine. This is a device typically found in casinos on blackjack tables. And the purpose of this moderately sized device? To shuffle the cards after each round of blackjack.

On the surface a CSM may not seem all that bad, but it is a sneaky moderately sized device and does do something to your bankroll that is not pleasing.

What CSMs really do is speed up the rate of play, meaning that you will play more hands per hour at a blackjack table with a CSM than you would at a blackjack table with just an ordinary shoe.

A shoe is a small device, as compared to the moderately sized device that is a CSM, that shuffles multiple decks, usually six or more, before the first round. The dealer will then draw from the shoe until near the end of the deck when the cards must all be reshuffled and placed back in the shoe.

On average there will be 20% more hands per hour when playing at blackjack table with a CSM than when playing at a table with a shoe.

Now in blackjack, even when played with basic strategy, the house will still have the edge. On average players will only win 48% of the time and lose 52%.

Follow the theory and you will see that players stand to lose more hands than they win. So the more hands you play per hour increases the number of hands you lose per hour, and increase the amount of money the casino will make off of your blackjack game.

While casinos adore their moderately sized CSMs, it is better for a player’s blackjack odds to play at a table with a shoe. The sole reason for playing in a shoe game is because you are playing fewer rounds of blackjack per hour, which means you stand to lose less in an hour than you would at a table with a moderately sized CSM.

Blackjack Strategy and Odds for Shuffle Machines

A good many blackjack players do not think twice when in a brick and mortar casino about what sort of shuffling is happening at their table. This is especially true of novice players who do not understand how shuffling impacts their blackjack odds.

And it is true, something as with seemingly as little consequence as a shuffle machine can indeed impact a player’s blackjack odds—and not in a good way.

I will cover online blackjack first as it is the simplest. There is only one kind of ‘shuffling’ in online blackjack, and it is like a Continuous Shuffle Machine (CSM). This is because when the RNG goes to pull the cards for the next round, it is pulling from all possibilities. This means that no cards are ever discarded. Hence, why online blackjack ‘shuffling’ is like playing with a CSM.

In online blackjack there is no choice on shuffling methods. Players just deal with the RNG and keep on playing. But players in brick and mortar casinos do have a choice. And often they make the wrong one.

When playing blackjack in a brick and mortar casino there are generally three different types of shuffling available: CSMs, non-continuous shufflers and hand shuffling.

For experienced blackjack players it is well-known that CSMs are the worst type of shuffling. Well, they are if you are a card counter as they make card counting impossible.

Sometimes novice blackjack players pick up on this, and so they deem CSMs as bad and avoid playing at tables that use CSMs. Good job, newbies!

However, a good many of them will play at tables with non-continuous shufflers. In truth, when you do not consider card counting, these are just as bad as CSMs. This is because all shuffle machines—CSMs and non-continuous shufflers—speed up the rate of play, and THAT is what hurts a player’s blackjack odds.

Both types of shuffle machines speed up the rate of play by around 20%. So say on average you play 100 rounds per hour; if you were playing with some sort of shuffler you would be playing 120 rounds per hour. The more rounds per hour you play, the more opportunities there are for you to lose money:

You are wagering $10 per game. If you lose 52% of the games—which does follow blackjack odds—you would lose $520. At a table with a shuffle machine you stand to lose $624 per hour.

It would be in a player’s best interest to include in heir blackjack strategy to not play at tables with shuffle machines. Why voluntarily hurt your blackjack odds like that?

Blackjack Odds of Winning and Losing

What makes blackjack one of the most popular casino games out there?

Simply put, it is the myth that blackjack is the one casino game in which the player can gain the edge and beat the house.

Truthfully that can happen. But it does not happen just from sitting down at the blackjack table or by logging in to your favorite online casino to play a few rounds. To beat the house at blackjack you must study the game, its rules and its strategies. It takes practice. And it also takes card counting.

So truth be told, online blackjack cannot be beat because a player cannot count cards. This is because the game functions similarly to a blackjack table with a CSM in a brick and mortar casino. A CSM is a Continuous Shuffle Machine, and it prevents any cards from being discarded because at the end of a round all the just-used cards are put in the little machine, the entire deck reshuffled and then the next round dealt.

So you must be playing blackjack in a brick and mortar casino—at a table without a CSM I might add—so that you can count cards. You also need to be playing according to basic strategy. Basic strategy drops the house edge to 0.5%. A skilled and practiced card counter can overcome the remaining 0.5% that is against them and then begin to tip the odds up to 1% in their favor.

So, yes, blackjack is a beatable casino game.

However, the majority of blackjack players will not spend the time to gain the necessary skill in card counting that is needed to overcome that last bit of the house’s edge. And still many others will not play according to basic strategy.

And while casinos to not want to seem like they are handing out money for free, they do not seem to mind the continued myth that blackjack is the beatable casino game. For them, it draws more and more new blackjack players that they wind up taking money from.

Even knowing that, players who want to become skilled at blackjack should still work and practice their blackjack strategy. Strategy is meant to improve blackjack odds. So even if you do not beat the house, you will lose less money with a sound blackjack strategy than if you did not have a blackjack strategy.

How Blackjack Odds Change

Because of the nature of the game, a player’s odds in blackjack are constantly changing. Well, they used to at least.

Because of the constant shuffling method of operation of a Random Number Generator (RNG) in online blackjack and the Continuous Shuffle Machines (CSM), the odds in those blackjack games stay pretty fixed. The reason for why the odds on those two types of blackjack stay the same, roughly, is because in regular blackjack the remaining deck changes.

A player’s blackjack odds traditionally shift throughout the course of the game. When a round ends, the cards that were just played are collected and set aside as discards. In other words, they are no longer in play.

With cards being removed from play it affects what the percentage of cards that are left in the deck. For example if there has been a run of low cards, it means that more low cards were being dealt and then removed from play at the end of each round. With those low cards gone, it leaves a greater number of high cards left to be dealt. A shift in cards like that is what causes the odds in blackjack to change.

When there has a been a run of low cards, like in the scenario above, the remaining high cards in the player’s favor, increasing the player’s blackjack odds. With high cards remaining there is an increased chance of being dealt a natural blackjack or having high double downs, both of which pay more and take away more from the house’s edge.

But when the run was a high card fun and the remaining deck is rich in low cards, it means a decrease in the player’s blackjack odds. This is because low cards favor the house and not the player. Dealers are more likely to hit to strong hands while a player busts or loses because of a stiff hand.

Because an RNG pulls from dealing outcomes that include all the cards in a deck it means that no cards are left out of the outcomes. This is similar to a CSM in that all cards are in play at all times.

This is can be good and bad. It is good because it means that the house does not have an advantage at times; but it is also bad because the player does not have an opportunity to have increased blackjack odds from discarded cards.
