I have stood on the studio floors in Riga and Malta. I have watched the “Mission Control” screens that monitor every dealer’s hand movement. The most common question I get at Casino545 is: “Is the wheel magnetized?” or “Did the dealer swap the card?”
The short answer is no, they are not using magnets. The long answer is more complex. They don’t need magnets to beat you; they have mathematics and pace. However, “glitches” do happen, and understanding the difference between a technical error and a rigged game is vital for your bankroll.
This article is a technical deconstruction of Live Dealer operations. We will look at the Game Control Unit (GCU), Optical Character Recognition (OCR), and the strict audit trails that major providers like Evolution and Playtech must maintain to keep their licenses.
The Brain of the Table: The Game Control Unit (GCU)
When you play Live Blackjack or Roulette, you are not just watching a video stream. You are interacting with a piece of hardware attached to every table called the GCU. It is about the size of a shoebox.
The GCU is the encoder. It digitizes the physical reality. When a card slides out of the shoe, it passes over a laser scanner. The GCU reads the barcode (or suit/rank image) and sends that data to your screen microseconds before you see the dealer place it on the felt.
The “Rigged” Myth: Players often scream “Rigged!” because the digital graphic of the card appears on screen before the card is fully visible on the table.
The Reality: This is latency. The data packet (3kb) travels faster than the high-definition video stream (5mbps). The system knows the card is the King of Hearts before the dealer has even let go of it.
Optical Character Recognition (OCR): How the Computer “Sees”
Live Roulette does not use a microchip inside the ball (usually). Instead, it uses advanced OCR cameras. These cameras track the ball’s velocity and the wheel’s rotor speed. Sensors detect exactly where the ball drops.
In 2026, the sensors are incredibly sensitive. If a dealer sneezes and vibrates the table, the system might trigger a “Void Spin.” This isn’t the casino trying to cheat you out of a win; it’s the safety mechanism kicking in. If the spin doesn’t match the expected deceleration curve, the software invalidates it to prevent players from cheating using prediction software.
The Shuffler: The Real “Black Box”
If there is a weak link in trust, it is the automatic shuffling machine (e.g., Shuffle Master). In manual shuffling, you can see the cards. In automatic shuffling, the cards disappear into a box.
These machines are audited. They use RNG (Random Number Generator) logic to ensure the clump of cards is mathematically random. However, deck penetration (how deep they deal before reshuffling) is a setting the casino controls.
The Counter-Measure: I always recommend playing at tables with Manual Shuffles where the dealer washes the cards on the table. It is slower, but it removes the “Black Box” paranoia. Evolution’s generic blackjack tables often use shoes; their VIP tables often use manual shuffles.

“Ghost Hands” and Video Freezes
A common scam complaint: “I had 20, the dealer had 16. The video froze. When it came back, the dealer had 21 and I lost.”
Is this intentional? Almost certainly not by the provider (Evolution/Pragmatic), but it could be a connection issue on your ISP or the CDN (Content Delivery Network).
However, the Audit Log is your protection here. Every single hand is recorded on the server. If the video fails, the game continues in the background. The server outcome is final.
How to audit this: Go to your “Game History” in the casino lobby. Replay the game round. Major providers allow you to watch the replay of the specific hand ID. If the replay shows the dealer drawing a 5, then the draw happened, regardless of your video lag.
The Dealer’s Ear: The Control Room
Dealers wear earpieces. They are not listening to music. They are listening to the Pit Boss or the Service Manager.
If a dealer makes a mistake—scanning a card twice, or paying the wrong position—the Control Room sees it instantly on their monitors. They speak to the dealer: “Stop. Call the Pit Boss.”
This is not “the casino deciding to stop a winning streak.” It is operational compliance. If they let a mistake slide, the Malta Gaming Authority can fine them millions. They would rather void your €10 bet than risk their license.
Are “Lighting” Multipliers Rigged?
Game shows like Lightning Roulette or Crazy Time use a hybrid system. The wheel is physical, but the Multipliers (500x, etc.) are digital RNG.
The RNG selects the lucky numbers before the ball lands. The physics of the wheel are real, but the bonus payouts are purely algorithmic. Is it rigged? No. Is it highly volatile? Yes. The math is designed so that the massive wins are paid for by the losing streaks of thousands of other players. It is not a rig; it is a very steep pyramid.
How to Spot a Fake Live Casino Feed
Believe it or not, pirate casinos stream recordings of live games. They take a video of a roulette wheel from 2024 and stream it in 2026, taking bets on the result.
The Chat Test: To verify you are live, type something specific in the chat: “Dealer, what time is it in London?” or “Dealer, please touch your left ear.”
In a real studio, the dealer will eventually respond or react to the chat flow. In a fake recorded stream, the dealer will ignore everything because they are just a video file.
Conclusion: The House Doesn’t Cheat, It Just Grinds
Evolution, Playtech, and Pragmatic Play are billion-dollar public companies. They do not need to rig a €50 blackjack hand. The risk-to-reward ratio is insane.
The game is “rigged” only in the sense that the odds are against you. The Green Zero is the rig. The 6:5 Blackjack payout is the rig. The machinery itself is audited, sealed, and watched by cameras 24/7. Don’t fear the magnet; fear the math.
Frequently Asked Questions (FAQ)
Can dealers control where the Roulette ball lands?
No. This is called “Sector Targeting,” and while some veteran croupiers can aim for a section, the varying rotor speed and lightweight Teflon balls used in modern online studios make consistent targeting physically impossible.
What happens if the scanner misses a card?
The system flags an error immediately. The round is paused. The Pit Boss enters the screen, checks the card, scans it manually, and the game resumes. If the error is unrecoverable, the round is voided and all bets are returned.
Are the cards in Live Blackjack different from real cards?
They are larger (to be seen on phone screens) and have barcodes on the side or corners for the GCU to read. Otherwise, they are standard material. They are destroyed and replaced regularly to prevent marking
Why does the dealer change every 30 minutes?
To prevent fatigue and collusion. A tired dealer makes mistakes. A dealer who stays at a table too long might develop a rapport with a player (“signaling”). Rotation ensures security.
Is Evolution Gaming rigged?
No. Evolution is audited by eCOGRA and Bureau Veritas. They operate in highly regulated markets like New Jersey, the UK, and Ontario. Any evidence of rigging would destroy their stock price and licenses globally
