In the quiet microcosm of the casinos, a very discreet workshop guarantees the seamless electronic and technical operation of the machines. Located in the basements of the Café de Paris Monte-Carlo, a team of about fifteen technicians, mechanics, and electronics engineers work diligently to maintain, repair, and update the equipment, ensuring that no malfunction disrupts the gaming experience. Every morning, this team also counts the banknotes collected from the slot machines. This service, led by engineer Alexis Bettacchioli for over thirty years, is now unveiling its unique expertise for the first time.

Behind the scenes at casinos
“Every day, more than a million euros pass through here.” Alexis Bettacchioli, head of the Electronic Games Workshop at Monte-Carlo Société des Bains de Mer, starts his day with a routine. At 8 am, in accordance with strict security and control protocols, a manager, cashiers, and agents responsible for the automatic machines conduct the "handover.” They collect the money accumulated from slot machines and tables over the past 24 hours, then transfer it to the counting room for verification and recording.
Act II: Maintenance of electrical and electronic equipment.
Rigour at the heart of the game
All components, including specific locks, security modules, the interface with the Casino Management System, and client card readers, must be adapted before installation. This process typically takes several hours per machine.
Every day, the equipment is maintained. Today, gaming tables feature displays, card dispensers and shufflers, and chip sorters—all electrical devices used by gaming staff that require servicing or repairs.
This job is so specialised that it is almost unique in its kind within a casino. “We are almost the only ones in the world to have a workshop capable of handling everything. Elsewhere, casinos simply replace faulty modules. Here, we repair them, which extends the lifespan of the equipment, reduces costs, and aligns with an environmentally conscious approach.”
Constantly evolving expertise
These eco-responsible actions are ahead of their time, considering this service originated with the introduction of the first slot machines at the Casino de Monte-Carlo in 1931. Originally, it involved continuously adjusting the mechanical machines. Today, it requires repairing electronic modules and blending tradition with responsible innovation by emphasising skill transfer.
The service also features five 3D printers that run nonstop. “It began with a small, out-of-stock, and very costly plastic part. Now, we produce precisely tailored chip racks, supports for integrating modules, and small components for other S.B.M. services whenever we can assist."
Several technicians, mechanics, and electronics engineers at the "Unique Jeux" service have been with the company for over thirty years. Alexis Bettacchioli explains, "What motivates them is the diversity of problems they face: no two days are identical. One day, we might be inspecting an electronic board under a magnifying glass; the next, we could be setting up a new slot machine.”
“Every detail matters. A malfunctioning machine or a poorly kept table can erode a player’s trust. Our goal is to ensure trust and deliver a flawless experience. Even if someone leaves without winning, they should feel they enjoyed themselves and received entertainment worth their investment. That’s the essence of Monte-Carlo.” – Alexis Bettacchioli, Head of the Electronic Games Workshop at Monte-Carlo Société des Bains de Mer.
