Generally, the Arcade game maker underwrites (or participates somehow) in the jackpot for their own machines, so they'd be able to track if affiliated individuals (employees, ex-employees, etc.) were winners. Obviously, it gets more complex if the offending engineer were to tell someone else the secret, etc., but that's already getting into organized crime territory.
