Pinball Roulette Machine
Automated Roulette game with a pinball-like plunger. The spring-loaded plunger is just a prop, though. An internal isolated launcher actually fires the ball, removing any possible “skill” element to make this purely a gambling game. Still cool.
There are a few old school bingo machines that also used a roulette wheel instead of bingo cards, so this is actually an old idea being re-imagined, but in those games, the plunger was real.
