If the casino were using 6 decks of cards, they will usually deal 4.0-4.5 decks and then place the entire 6-decks into the automatic shuffler for shuffling while continue to play with the second set of freshly shuffled 6-decks of cards. With an automatic shuffler, about 70-75% of the cards are dealt out before the cards are reshuffled.

First, let’s make sure you understand what a CSM is because players often confuse them with automatic shufflers. The latter have been around a long time in casinos.

Learn how to read a blackjack strategy chart and find examples of a 6 deck black jack strategy charts to use while playing online blackjack games. How Many Decks Are Used in Online Blackjack is a key question when playing blackjack and it’s extremely important to know the answer before playing. This is a question that has more than one answer, as there are several types available to play. Blackjack is typically played with six decks of 52 cards, although it can be played with just one or even more. The number of decks used by the dealer has a direct impact on the house edge. The house edge is just 0.17% when you play single deck blackjack versus 0.64% when six decks are used by the dealer. In fact, you will notice that when playing a single-deck game of blackjack many casinos only offer a 6:5 payout for blackjack, while multi-deck games offer 3:2. If you placed a $10 bet and got blackjack on a multi-card game with 3:2 payout you'd walk away with $15, whereas you'd only get $12 for a single-deck game with a 6:5 payout.

Usually a casino will use two sets of multiple decks of cards on a blackjack table.

While one set of cards are used to play the game the other set is being shuffled offline by the automatic shuffler. When the cut card appears, the round is completed and then the dealer will swap the cards-the just used multi-decks will be placed in the automatic shuffler to be shuffled while the shuffled decks that were in the machine are put into play. The purpose of the automatic shuffler is to eliminate the wasted time involved in having the dealer manually shuffle the cards (from the casinos perspective, time is money, so their hourly profit goes up when they eliminate the wasted time in manually shuffling the cards).

The odds against the player in blackjack do not change when an automatic shuffler is used on the table to shuffle the multi-decks of cards. If the casino were using 6 decks of cards, they will usually deal 4.0-4.5 decks and then place the entire 6-decks into the automatic shuffler for shuffling while continue to play with the second set of freshly shuffled 6-decks of cards. With an automatic shuffler, about 70-75% of the cards are dealt out before the cards are reshuffled. This is an important point to remember.

The CSM was invented primarily to discourage card counting at blackjack. But it also has a negative effect over average players as you will soon see.

A CSM is a combination automatic shuffler and dealing shoe. Casinos usually place 5 decks of cards into the CSM. After a betting round is completed, the dealer will scoop up the just played cards (discards) and instead of placing them into a discard tray will insert the cards back into the CSM for shuffling with the remaining 4.5 or so decks of cards. (Some casinos will place the discards from several rounds into a small discard tray and then scoop up the deck or so of discards and place them back into the CSM).

Do you understand the difference between a CSM and automatic shuffler? With the latter most of the cards are played (ca. 70%) before the discards and unplayed cards are reshuffled. With a CSM, the discards are immediately returned to the shuffler to be randomly mixed with the unplayed card. . It’s possible that a specific card from the round just played might wind up being dealt in the next round.

So do the odds change when a CSM is used? The answer is yes, they change very slightly in favor of the player with the house edge against a basic strategy player in a typical 6-deck game reduced by about 0.1%.

The reason the CSM causes the house edge to go down ever so slightly is because of a phenomena known as the “cut card effect” (this increases the probability slightly of getting tens and blackjack when a CSM is used).

Now before you rush out and play blackjack on a table that uses a CSM, listen to the rest of the story. Even though the house edge goes down slightly with a CSM, this is more than negated by the increased speed of the game. Remember with a CSM dealt game there is never any down for shuffling cards. So on average the casino can deal about an extra round or two per hour resulting in about 20% more hands played per hour with a CSM and because they have the edge against the vast majority of players who play blackjack their hourly revenue goes up by 20%. From the player’s perspective, you will lose 20% faster on average playing against a CSM dealt game compared to a game dealt manually or with an automatic shuffler.

Casinos love to spin the tale that the reason they use a CSM is to foil card counters.

Yet you will rarely see a CSM used at high limit tables where most of the pro card counters would play. The reason is that most high rollers who know nothing of card counting are suspicious of the CSM and they insist that blackjack should be played the old fashion way or they will take their business elsewhere.

So in most casinos you will find CSM’s on the main casino floor where the table minimums are lower. It’s here on the $5 and $10 tables where the casino grinds out it’s 20% more revenue per hour against average low stakes players.

Casinos also like CSM’s because it allows them to always have the edge just like they enjoy with all their games. By using a CSM, blackjack becomes virtually unbeatable much like roulette, baccarat, Three Card Poker and other table games.

CSM’s are not cheap. Casinos coast to coast have been testing them for the past several years. In some casinos the devices were removed because of player complaints or because the extra revenue didn’t justify the extra cost of these devices. Nevertheless, casinos keep putting CSM on their tables in the hopes that the playing public will get accustomed to them.

My advice is to stay away from any blackjack table that uses a CSM. If more players do this casinos will reluctantly have to remove the machines and return to the more player friendly automatic shufflers (or manual shuffles). Blackjack is tough enough to beat without introducing devices that cause average player’s to lose more quickly.

Single Deck Blackjack

There was a time that Las Vegas was flush with single deck blackjack games that paid 3-2 on an ace and a face. That is no longer the case. Most single deck blackjack games in Las Vegas only pay 6-5 on a natural.

El Cortez, located just east of the Fremont Street Experience downtown, is one of two casinos in Las Vegas that still spreads 3-2 single deck blackjack. The game is found at most of its tables. The minimum bet is usually $5, but peak hours may become $10. Players may double down on any two cards but not after splitting. The dealer hits soft 17. Split aces receive only one card each. Surrender is not permitted.

Silverton offers single deck blackjack. It is down to just one table at this locals’ casino located south of the Las Vegas Strip. The rules are a bit tighter here than they are at El Cortez. Players may only double down on 10 and 11 and not at all after splitting. The dealer hits soft 17. Re-split aces and surrender are not permitted. The minimum bet is usually $10.

Blackjack players willing to drive an hour will find a good single deck game in Mesquite. It is at Eureka Casino. Players may double down on any two cards and double after splitting. Like the Las Vegas single deck games, the dealer hits soft 17 and there is no surrender or re-split aces. The bet limits for this table are $10 to $100.

What Happened to 3-2 Single Deck Blackjack Games on the Vegas Strip?

Unlike real money blackjack tables online, there are very few 3-2 single deck blackjack games on the Las Vegas Strip these days. These casinos tightened up over the years. Single deck games became double deck or shoes with six or eight decks. The single deck games that remained started paying 6-5 on a natural.

Casinos bet on the fact that players would still give action to 6-5 single deck games with the attitude that they wouldn’t know how much that affected the odds or just not care. The belief among some gamblers was that 6-5 single deck is still better than a 3-2 game with more decks. Unless there are unusual rules, this is simply not the case.

What You Can Play Instead?

Players that do not have access to the 3-2 single deck games should choose double deck games. At Treasure Island, players will find a $10 double deck with double down before and after splitting. This game hits soft 17, however, for $25 the dealer stands on all 17’s. Most MGM properties offer the hit soft 17 game for $25 and stand on all 17 games for $50 or $100.

Single Deck Blackjack Games in Vegas

Even though there are no 3-2 single deck blackjack tables in Vegas, there are still plenty of one-deck tables. In this survey you will find all the casinos in Las Vegas that have single deck games.
