So how does that deal with a hardware failure when your controller shorts and powers all the pins?

It's not so easy to run thousands of machines over decades with zero malfunctions. Obviously the code doesn't return million dollar payouts.

Have the number written on a 4 digit screen (or 5 or 6 if you want) like for clock or sport. Even with malfunction, it can't give more than $9999.
