The best "dark pattern" trick from Las Vegas casinos may be to start pumping pure oxygen thru A/C around midnight, so guests would get some "high" boost, keeping them gambling harder and tirelessly all night long. I read about this many years ago in "Fools Die" by Mario Puzo, which of course is fiction, but I think there may be some truth in there (One of the characters in the book is mostly based on the author himself). Edit. Found an original quote from the book: Gronevelt was dressed to go down to the casino floor. He fiddled with the control panel that would flood the casino pits with pure oxygen. But it was still too early in the evening. He would push the button sometime in the early-morning hours when the players were tiring and thinking of going to bed. Then he would revive them as if they were puppets. It was only in the past year that be had the oxygen controls wired directly to his suite.

Building fires would sure be exciting!

  Ah! I don't think they need so much oxygen to be a fire hazard. People would start acting crazy, at least. I also wonder if they use to do the same - to some extend - in trains and airplanes, I always feel quite relaxed while traveling by them.

> One of the characters in the book is mostly based on the author himself Fun fact: Puzo had a serious gambling problem. He did most of his research for The Godfather while gambling in a Las Vegas casino (or several?) and interviewing the manager.

Casinos do not now nor have they ever pumped oxygen into their buildings. It's nothing more than a myth.

  This is true, however may be worth noting that I’m sure they (along with many large commercial buildings non-specific to casinos) control the carbon dioxide levels inside, and increase air exchange with the outside when necessary. High carbon dioxide levels do have a lethargic effect

    Any LEED certified building will do that.

    Lets not forget that casinos also allow smoking on the gambling floor, so excess air handling and filtration capacity is a necessity.
