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.
