This reminds me of exploits we used to do to arcade cabinets back in Sydney in the 80's and 90s. The school gas heaters used to have what we called "clickers", piezoelectric ignition devices you could remove from the heaters.

You then took that clicker to your local arcade, and clicked one of the corners of the CRT, that would send a shock through the system and add credits to your game. I believe this was because the CRT was grounded on the same ground lines that the mechanism for physically checking a coin had gone through the system.

Suffice to say, they caught onto this over time, and added some form of an alarm into it. But up until then... Those were truly the best times.

This brings back a vague memory of smacking the side of a pinball machine just right and getting a free game. I bet it was the same concept.

You were likely causing the spring-loaded mechanism that detects a coin insertion to make physical contact.
