After all, he sees these lights blinking all the time!Īlthough incorrect, I can see why the reader jumped to the conclusions he did. He then assumed the reason for putting them out of order was to tighten them, and pointed out to me that my recent article on how difficult, time consuming and rare it is for a casino to tighten a machine must be a bunch of hogwash. One of my readers recently assumed the blinking lights meant the machines were being placed out of order. Most of us have figured this part out, but what about when you see either one or both of the lights blinking? If a player hits the “service” button, the top (white) light will turn on and remain on, signaling to the next slot host to walk by that the player needs attention. They just sit there for no apparent reason. Nine times out of 10, these lights are off. The bottom color actually indicates the default minimum denomination of the machine, usually red for dime and below denominations or yellow for quarters, and the top light is always white. Sometimes called tower lights or candles, they are white on the top and colored on the bottom. Virtually every machine has them – a cylindrical light placed dead center on top of the machine, with two colors stacked one on top of the other. Take those lights on top of the slot machines for instance. In fact, too many secrets can lead to a feeling of distrust, and casinos can ill afford to be labeled as untrustworthy in an economy like this. While I agree a measure of mystery lends to the superstitions that make gaming so much fun for so many people, it is certainly not necessary to keep everything a secret. This is where casinos, in my opinion, have somewhat failed themselves in recent times. Casinos aren’t allowed to keep secrets from the government and law enforcement, yet many seem to insist on keeping as much from the general public as possible.

Every state that allows a form of casino gaming also has a separate law enforcement division devoted entirely to ensuring those games are run honestly and legally. The casino industry is one of the most closely monitored and regulated industries in the U.S.
