“Discover the Electromechanical Secrets Behind Classic Pinball Machines”
For decades, pinball machines were the go-to source of fun and entertainment. But, beneath the glossy exterior and electronic sounds that have charmed generations, lies a complex and intricate array of electromechanical components. Join us as we take a look behind the scenes and uncover the hidden history of these wonderful machines.
Understanding Pinball Machine Mechanics
Before microcontrollers, video game companies relied on electromechanical components to devise complex play aspects and gameplay. With the help of a unique network of motors, switches, solenoids, relays, and more, a seemingly simple game of pinball came to life.
For a better idea of just how complicated pinball machine mechanics can be, consider a machine that supports a single player and a limited number of targets. When the ball strikes a target, it triggers a micro-switch – and that switch in turn prompts a relay to close a contact for a short period of time.
This contact then energizes a solenoid, leading to the score wheel spinning on by a few notches and granting the player ten points. To ensure the scoring wheel has been given enough time to rotate, companies included something known as a mechanical flip flop.
The Challenges of Designing Pinball Machines
Of course, designing pinball machines involves much more than setting up a few relay circuits here and there. From the score counter resetting at the start of the game to the counting of balls in play, a lot more goes into creating the complete pinball game experience.
When we consider the design of real games, things become even more complex with multiple players, bonus sequences (i.e. hit the red target three times to earn double scores for other targets), and a range of other features.
The Origins of the Pinball Machine
While today’s pinball machines don’t physically include pins, the original machines (which have to date been the most intricate examples of electromechanical assemblies) are thought to have acquired their name from the fact that they mimic ‘pin-balling’ – a game played with pins and balls.

Conclusion
Pinball machines have thrilled generations of people with their flashy façade and nostalgic sounds, but the real beauty lies beneath the surface – where an intricate array of electromechanical components work together to create a world of endless entertainment.
