A "Game King" machine was most likely made by IGT, and Nevada regulations require that all machines made by any manufacturer licensed in Nevada must meet Nevada specs. Therefore, it's probably safe to say that the machines were honest when they left the manufacturing plant.

Of course, that can't prevent an unscrupulous casino from putting in a bogus program chip after it's delivered. But you have to ask yourself what the incentive would be? Most people will play regardless of how bad the payoff schedule is, so all they have to do is select payoff schedules with the expected hold that they want. Rigging machines will only result in bad word of mouth and a drop in business.

I doubt the machines were rigged, but, at the same time, I am a little leery about the regulation enforcement outside of Nevada.
