Quick Takeaways
- Shuffling machines help casinos reset the deck more often and increase hands per hour.
- Frequent shuffling reduces the impact of deck composition changes that counters look for.
- For most players, the practical effects are pace, rhythm, and faster exposure per hour.

Why Casinos Care About Card Counting
Card counting is based on a simple concept:
deck composition changes as cards are dealt.
When the remaining deck becomes rich in high cards, a counter can:
- adjust bets
- and sometimes adjust plays
to gain a small advantage.
Casinos don’t want to rely only on surveillance or banning players.
Instead, they often use procedures that reduce the opportunity in the first place.

What Shuffling Machines Are (In Simple Terms)
A shuffling machine is a device that:
- shuffles cards faster and more consistently than a human dealer
- keeps the game moving with fewer pauses
- and can change how often the deck gets reset
Different casinos use different systems, but the effect is usually the same:
less time with a stable, deep shoe.
The Two Main Types of Shuffling Machines
1) Batch Shufflers (Between Shoes)
These machines shuffle a full stack of decks at once while the dealer is finishing a shoe or preparing the next one.
What it does:
- speeds up the shuffle process
- reduces downtime
- increases hands per hour
Counting can still exist in shoe play, but the table moves faster and resets more efficiently.
2) Continuous Shuffling Machines (CSMs)
This is the big one.
A CSM continuously mixes used cards back into the shuffle during play.
That means the deck is constantly being “reset” in the background.
Practical effect:
- the shoe never becomes meaningfully “rich” or “poor” in the way counters rely on
- because cards are constantly being reintroduced and reshuffled
This is why CSM tables are often described as “counter-unfriendly.”
How Shuffling Machines Reduce Penetration
Penetration is how deep into the shoe you get before a shuffle.
Deeper penetration gives the deck time to drift away from neutral, which is what advantage play relies on.
Shuffling machines (especially CSMs) reduce this effect by:
- creating earlier or more frequent resets
- preventing the deck from staying “stable” long enough to become exploitable

How Shuffling Machines Change the Game for Regular Players
Even if you never count cards, you will feel the difference.
1) Faster Pace (More Hands Per Hour)
Shuffling machines reduce downtime, which increases the number of hands dealt.
That can be fun, but it also means:
- more bets per hour
- faster swings
- and faster expected losses per hour (since more hands are played)
If you struggle with rushing or tilt, faster tables can be a negative.
2) Less “Rhythm” in Shoe Flow
Some players like the feeling of a shoe progressing naturally.
CSMs can feel different because:
- the deck doesn’t “develop” in the same way
- outcomes feel more random and less connected (even though blackjack is always probability-driven)
3) Fewer Opportunities for Advantage Play
If you’re a regular recreational player, this may not matter.
But it explains why:
- some strong players avoid CSM tables
- and prefer deep shoes with predictable shuffle points
Should You Avoid Shuffling Machines?
Not always.
For most players, the decision is about:
- table rules (3:2 vs 6:5, S17 vs H17)
- comfort and pace
- your ability to stay disciplined at higher speed
If the machine table has:
- good rules
- and a pace you can handle
…it can still be a solid choice.
But if the game is:
- very fast
- and your decisions get sloppy
…then the “efficiency” becomes a problem.
Mini FAQ: Shuffling Machines in Blackjack
1) Do Shuffling Machines Make Blackjack Worse Odds?
They don’t automatically change payout rules, but they can increase hands per hour and reduce advantage opportunities for counters.
2) What Is a Continuous Shuffling Machine (CSM)?
A machine that continuously mixes used cards back into the shuffle during play, limiting deck composition drift.
3) Can You Count Cards Against a CSM?
Not effectively in the traditional way, because the deck constantly resets.
4) Why Do Casinos Like Shuffling Machines?
They increase efficiency, reduce downtime, and reduce advantage play opportunities.
5) What Should Regular Players Do?
Prioritize good rules and a pace you can play accurately.
