It is a common trope in movies/tv for a character to be card-counting in a casino, but I think it is not possible to do anymore as casinos have all switched to multi-deck dealing systems, 6 or 8 decks, reshuffled halfway through. Do any casinos still do single deck blackjack ?

You actually can still count cards in 6-deck or 8-deck shoe games! Counters simply convert the "running count" to a "true count" by dividing by the estimated number of decks left in the shoe.
As for single-deck Blackjack, some casinos still offer it (especially in Las Vegas), but it's usually a trap. Most single-deck tables only pay 6:5 on a Blackjack instead of the traditional 3:2, which instantly wipes out any advantage from counting.
The real killer for card counting isn't multi-deck shoes—it's Continuous Shuffle Machines (CSMs), which feed used cards back into the machine after every single round.

Yes, absolutely—though they work a bit differently depending on where you play:
* Land-Based Casinos: Very common on low- to mid-limit Blackjack tables. Casinos use CSMs to speed up dealing (more hands per hour) and completely eliminate card counting. Higher-limit tables are usually where you'll still find traditional shoes or manual shuffles.
* Online (Digital / RNG) Blackjack: Software games use a digital equivalent of a CSM. The algorithm reshuffles the entire deck after every single hand, making card counting impossible.
* Live Dealer Online Games: Major providers (like Evolution or Pragmatic Play) usually use physical 8-deck shoes rather than CSMs. However, they set the cut card right around 50% penetration (halfway through the shoe), which stops card counters from getting a strong edge.
So whether it's a physical CSM on the floor, an algorithmic reset in digital games, or a shallow cut card in live streams, casinos keep card counting pretty well neutralized.

I think it doesn't work now. If we talk about online games, it definitely doesn't work, but in a live casino, I think nowadays security is at such a level that no amount of card counting will help you anymore.

I have no idea if casino is still use a single deck black jack but in general I doubt card counting is that profitable because they gona catch you sooner or later.

Even if you find one single deck blackjack, the casino will start counting… you. :ROFLMAO:

In any casino, they may not let you play blackjack if they notice that you know how to count cards. This may be grounds for a ban. You may be able to use your skill a few times, but in the long run it does you no good.

I dont think you can find any single deck games on the strip that use the "good" or more favorable odds.

Heard the Grand downtown offers $1 single deck but they shuffle after each hand.

guess you gotta get good enough to play at a high limit table with a traditional shoe !

6 or 8 decks is not the problem. Card counters do very well with that.
The problem now is the automatic shufflers that most casinos have implemented.

Most casinos don't. And if they do, they'll only have one single deck table on the whole floor, maybe two.
