A persistent Las Vegas myth has casinos pumping oxygen onto their floors to keep players alert and playing.
One of the most enduring myths of Vegas is that casinos pump oxygen onto casino floors to keep players alert and increase their playing time. Could this be true? How did this myth begin?

“The rumor regarding the pumping of oxygen into casinos is not true,” Tony Cabot, distinguished fellow in gaming law at the University of Nevada, Las Vegas, told Casino.org. There are many reasons for this. For one thing, the average Las Vegas casino has 1 million cubic meters of air. According to Arizona heating, ventilation, and air conditioning firm Parker & Sons, increasing the oxygen level by just a single percentage would require more than 40,000 cubic metres of oxygen gas each day. This would be an enormous expense. The oxygen itself isn’t flammable.This would violate all casino fire insurance policies, and if a fire were to occur, the investigation would lead to a public relations nightmare.

“Casinos do a number of things to encourage people to continue to play,” Cabot said. It’s just one of those myths about Las Vegas that people like to spread. It’s just one of those myths about Las Vegas that people like to spread.”

Author You Can’t Refuse

This myth springs from the fertile imagination of Mario Puzo, the late author of “The Godfather.”

In Puzo’s 1978 novel, “Fools Die,” casino owner Alfred Gronevelt places a regular 2 a.m. call to his building engineer “to pump pure oxygen through the casino air-conditioning system to keep the gamblers from getting sleepy.”

In the 45 years since the book’s publication, conspiracy theorists have circulated this fiction as fact. Some legitimate media outlets have also joined the conspiracy. One 2006 BBC article builds the myth up as true to make the point that “such psychological trickery would be banned in Britain.”

do fill the air with things to entice players to keep playing. This includes loud music, pleasant smells, and freezing AC. Cabot explained that clocks are not displayed in most casinos because they alert customers to the fact that it is time to leave. This would not be in their best interests. Cabot said that casinos sometimes make it difficult to find exits, but other times they don’t. But you’ll notice that the exits are such that they don’t allow visible light into where the players are playing.”Look for “Vegas Myths Busted” every Monday on
