me big dumb i dont know how to post videos if a mod can fix

(im glad this issue is finally getting some main stream attention)

Just put the Youtube video's alphanumeric found after the = sign or the / sign in the above option shown above to the left of the spoiler option which is left of the Twitter bird in the options above. The alphanumeric in your case is JQ20ilE5DtA

It is cool to finally see some mainstream video explaining it. Damn it was frustrating here in 2+2 threads years ago trying to say this could be done and several buttheads derailing threads saying it can't be done.

I know they're trying to do good here, but it seems like publishing the video is just going to notify a lot of prospective cheaters of new opportunities.

Correct me if I'm wrong but in order for this to work, you would have to somehow have access to the USB ports of the shuffling machines. Assuming you are colluding with the dealer or someone on staff, I guess it can be possible but highly unlikely to be successful long term.

The thing is, I have to imagine most big casinos are sophisticated and secure enough to prevent this from happening. There are likely a series of controls/safeguards in place to prevent someone like a dealer or casino employee from having easy access to the shuffling deck machines firmware. I would suspect that while it's possible to cheat, you would need several people on the staff "in on it" to fully carry this out in a place like Aria or Bellagio or something.

All that being said, I would probably never play in private or underground games for this very reason.

Pretty much, at that point(dealer/house compromised) it's easier just to introduce manipulated decks/IR camera tech/cheating devices

iirc back when the deckmate stuff first came out, it was also known that people pretty often used the usb ports for charging their phones without anyone stopping them

I have never seen a usb port on a shuffle machine used to charge a phone. Many if not most rooms have charging ports available but these are not the same and are not networked or connected to the one on shuffle machines.

The proposed way to cheat inthe video is possible but very difficult to pull off in a regulated casino. The video even says this. The video also contradicts itself in multiple places.

The method described in the video has been known here for years. It may have occurred in a cardroom in TX back in 2022 at Prime. But has never been known to happen in regulated casino or card room.

This method also has nothing to do with anything that OP posted

Much more likely to run into marked deck, hold card switching, collusion or one of the other cheating means that have been around many many years.

It seems trivial effort for a casino to take security measures to prevent the USB port from being accessed.

I don't play in casinos so can you explain to me why this port is even accessible to players, is there a reason why players need to use it?(someone mentioned phone charging which if so needs to be stopped given this vulnerability). If not then this port should surely be inaccessible to players.

I don't think it's been stated in any of the reports about this vulnerability, but I expect the port's purpose is for software updates and/or troubleshooting.

There is no legitimate reason for players to access it; at least not since USB charging ports have become popular on or near the top padded rail of tables.

But if you climb under a table -- then there it is on the side of the shuffle machine, open and vulnerable.

Agree there s no legit reason why player would need to access the usb but I have never seen a player plug into one either. And it isn’t like it is readily accessible. You are not going to nonchalantly plug in you phone so being noticed. But even if you did it takes more than that. How do you plan to reprogram the dm while in operation. Has the hash been moved to rom? Etc

All of this is possible but not easy. Effectively not possible wo inside man. You are much more likely to be cheated in a low tech old fashioned way. Casino cheating happens every day but this kind has never been seen.

After watching this video, I am less concerned about being cheated using this technique at a Las Vegas casino

It's not a practical approach even if you assume the shuffle machines haven't already been given extra protection.

Yeah seems near impossible to implement. Not that it would be easier but if you were going to get an inside person and attempt this you are better off trying penetrate one used for pai gow or some other jackpot game where you can hit one hand and get a 6 or 7 figure payout

So Robbi did cheat

I thought dealers mostly hand shuffled the deck anyway?

Not in casinos and not in years

Tobey Maguire insisted on Molly Bloom using his own Deckmate. Pretty easy to see why.

Until the end of her game, that would had to have been an original deckmate. It would also had to be in the New York game. Molly was arrested in 2013 but the deckmate 2 was not released until 2012. And few were available outside casinos initially.

Industry Standards in Casinos using DM2 should change because worldwide because of what's been exposed. Even if it's such a small risk why not create countermeasure to eradicate what's been exposed!

The following step would solve this:
Once the deck mate 2 has finished, the operator can pull the deck out, then rifle the cards just once before a cut each time deck is drawn from the DM2. This would eradicate the order of the known cards. Very simple step to implement.

Let's do it!

Maybe you didn't watch or understand the exploit/hack propely

Cutting doesn't solve anything the order of dealt cards is known and can be figured out after a cut!

They specifically designed and advertise the ability of the machine to create specific hands claiming it was so useful for duplicate bridge. Look at who leases them and see why they really did it.

Back when the original shuffler came out I worked a show with a 3 card poker tournament (pit game) sponsored by Shuffle Master. I asked the President of Shuffle Master if it could be used for a duplicate poker or bridge tournament, where the seed machine was doing a random shuffle, all the connected machines would do the same sequence. He said yes.

From Gemini, The company Shuffle Master developed its first automatic single-deck shuffler in 1989. It sold its first automatic shuffling machine to Bally's Casino in Las Vegas in January 1992, and the company went public that same year.

If a sorted deck was used then all the machines could put the cards into the same positions. But the key is all the decks have to start in the same order.

But since the original could not identify the specific card, if the starting order is unknown so is the final order.

The key is the original machine have no equipment to id cards so the starting and ending orders can’t be known unless the deck inserted is sorted. No cameras, no rfid, no scanner, etc.

This is why the original DM could only say if a fouled deck was short or long in cards. It could tell you if an extra card was present. The DM2 can tell which specific card is missing or if a certain card is duplicated.

So unless the dealer was order sorting the deck every time before putting deck in, there is no means to use the original DM to stack or know the deck.

This was a really well done video. A bit scary how it can be done.
