alt Hacker NewsI fondly remember finding and exploiting a buggy slot machine on the night the Euro got introduced. A classmate (I never played slot machines) made some money but didn't understand what was going on. I observed and it became apparent (in my slightly intoxicated state) the machine would pay out 2 Euro coins where is should pay out 20 cents. And when playing a 1 Euro game, you would often "win" 80 cents. Pay-out immediately and you got 8 Euro. Of course after a few rounds, the 2 Euro coins ran out and it would do some RNG to pay out 1 Euro with 80% chance. Don't know if I tried feeding it back the 2 Euro coins, I recall just made enough to have a free new years eve

How did something like this not pass a Monte Carlo simulation, which I'd assume they'd conduct in an audit?
that was possibly just some attendant accidentally messing up which hopper they refilled (or with which coins), or someone screwed up the assignment on the control board which hopper was connected to which bus identifier.
Reminds me I gotta eventually write up what I found reverse-engineering the one armed bandit in my basement LOL
That reminds me of a vending machine ran into as a little kid. It was in a private place and it had an out of order sign posted. Being hungry and young, I plugged it back in so I could take my chances. Every time I put in a quarter, three or four would fall into the coin return. When it was time to leave, all of the pockets on my cargo shorts were bulging so much that I had to hold my shorts up.
